G2: Discovery assessments

Relationship to enquiries 

 

“In essence, under the self-assessment scheme a taxpayer is obliged to make a tax return by the 31 January following the year of assessment and assess his own tax liability. HMRC can open an enquiry into the return (in which case the assessment remains subject to enquiry until the enquiry is closed by the issue of a closure notice), but unless an enquiry has been opened within 12 months after the filing date (referred to as the enquiry window), the assessment becomes final, subject only to the possibility of a discovery assessment under s. 29.” (Hargreaves v. HMRC [2014] UKUT 395 (TCC), §19).

 

Assessment issued within enquiry window

 

“Mr Laurie could have opened an enquiry into the 2011/2012 tax return since he was within the time limit set by Schedule 18 to do so. Instead he issued a discovery assessment under paragraph 41 of Schedule 18, relying on the circumstances in paragraph 43, namely that the company had carelessly or deliberately brought about an underassessment of tax.” (Easinghall Ltd v. HMRC [2016] UKUT 105 (TCC), §22).

Discovery assessments not an exception to any general rule

 

“The discovery assessment provisions are not an exception to any general rule.  They merely represent a part of the tax charging machinery which applies in particular circumstances where self-assessment, and the ability of HMRC to amend a self-assessment, is no longer applicable.  They fall to be construed accordingly.” (Clark v. HMRC [2017] UKFTT 392 (TC), §24, Judge Berner).

Relationship to enquiries 

- No assessment during enquiry window in reliance in s.29(5)

 

"[53] We can deal with this ground of appeal quite briefly.  We do not accept HMRC’s submissions or the views of the FTT in this case.  In our view, the legislation and its intended effect are clear.  Section 29(3) TMA states that the taxpayer “shall not be assessed” unless one of two conditions is satisfied.  In a case like the present where the condition in section 29(4) is not applicable, the words of section 29(3) amount to an unambiguous prohibition on any assessment being made while the conditions in section 29(5) have not been met.  We also agree with the FTT in Curtis at [87] that the validity of a discovery assessment must be tested at the time it is made.  The conditions in section 29(5) are temporal as is made clear by the words “at the time when”.  It follows that a discovery assessment made during the ‘enquiry period’ is invalid because the conditions in section 29(5) cannot be satisfied at that time.  As the FTT in Curtis pointed out, HMRC’s view would mean that the validity of an assessment would remain uncertain until the end of the enquiry period.  We do not accept that a discovery assessment issued during the enquiry period can exist in an indeterminate state like Schrödinger’s cat until the enquiry period ends." (Norton v. HMRC [2023] UKUT 48 (TCC), Judge Sinfield and Judge Paines)

"[71] On the facts of this case, Section 29(3) provides that Mrs Curtis shall not be assessed under section 29(1) unless one of the two conditions is satisfied. It is clear that the second condition was not satisfied at the time of the Assessment. It could not be satisfied at that time because the time for an officer of HMRC to give notice of an intention to open an enquiry into Mrs Curtis’ return had not expired. Mrs Curtis submitted her return on 19 May 2016. Mr Turnbull accepted that the effect of section 9A(2)(b) TMA 1970 was that HMRC had until 31 July 2017 to give notice opening an enquiry. Instead of opening an enquiry, HMRC chose to make a discovery assessment on 17 February 2017. In circumstances where HMRC cannot rely on the carelessness of the taxpayer, the question which arises is whether they can make a valid assessment before the “enquiry window” has closed.

...

[81] In our judgment, the scheme of section 29 is clear. It was not intended that HMRC should make a discovery assessment prior to the end of the enquiry window. It is implicit that the discovery required by section 29(1) is a discovery made after the closure of the enquiry window or after an enquiry has been opened and closed in circumstances where HMRC were not aware of the deficiency.

[82] Mr Turnbull made the point that what is postulated in section 29(5) is a hypothetical officer of HMRC. That is undoubtedly right (see HM Revenue & Customs v Lansdowne Partners [2011] EWCA Civ 1578). Further, the information available to the hypothetical officer at the relevant time, from which he could not reasonably have been expected to be aware of the deficiency, is the information specifically defined by section 29(6).

[83] It seems to us that the observations in Hankinson do not support HMRC’s arguments as to the validity of the Assessment in the present case. If anything, we consider that they support the invalidity of the assessment. If the Assessment should not have been made because neither of the conditions was satisfied, then it is invalid. HMRC’s argument rests on the proposition that an assessment which is invalid when made, can somehow be validated if, when the enquiry window closes, the taxpayer has not provided any information from which the hypothetical officer might reasonably be expected to know of the insufficiency of tax.

[84] In our judgment that proposition must be wrong. The condition in section 29(5) is looking back at the position when the enquiry window closed. Hence it refers to the time when the officer “ceased to be entitled” to open an enquiry. If Mr Turnbull was right, Parliament would have left open the possibility that such a date might be in the future. The wording would have been “ceases or ceased”.

[85] The purpose of the two conditions in section 29 is to protect both the taxpayer and HMRC. The taxpayer is protected from an assessment if he has not been careless and if in the course of making a return, or in the course of an enquiry into a return, he has made available information from which a hypothetical officer should reasonably be expected to be aware of the deficiency. HMRC are protected because they are entitled to make a discovery assessment if the taxpayer is careless in completing a return or if the taxpayer fails to provide information from which the deficiency should be apparent by the time the enquiry window closes. HMRC do not require that protection in a case where they are still entitled to open an enquiry.

...

[92] We are not satisfied that either of the conditions required by section 29(3) was satisfied and the Assessment was therefore invalid. There is no provision for an invalid assessment to be subsequently be validated. We have come to a different conclusion to that of the FTT in Tim Norton Motor Services, but the same conclusion as the Special Commissioner in Lee. Our conclusion on this issue is sufficient to dispose of the appeal." (Curtis v. HMRC [2022] UKFTT 172 (TC), Judge Cannan)

- No assessment during enquiry window in reliance in s.29(5)

Conditions tightened on move to self-assessment 

 

“Although 'discovery assessments' have a long history it is common ground that the circumstances in which they may be made were tightened on the introduction of self-assessment.” (Hankinson v. HMRC [2011] EWCA Civ 1566, §3).

 

“As I have already observed, apart from a closure notice, and the power to correct obvious errors or omissions, the only other method by which the Revenue can impose additional tax liabilities or recover excessive reliefs is under the new s 29. That confers a far more restricted power than that contained in the previous s 29… These provisions underline the finality of the self-assessment, a finality which is underlined by strict statutory control of the circumstances in which the Revenue may impose additional tax liabilities by way of amendment to the taxpayer's return and assessment.” (Tower MCashback LLP 1 v. HMRC [2010] EWCA Civ 32, §24)

Conditions tightened on move to self-assessment 

Best judgement

 

"[236]     Although paragraph 41 of schedule 18 does not in terms require a “best judgement” exercise, the requirement that the assessment is made “in the amount… which ought in his opinion be charged in order to make good to the Crown the loss of tax” in our view requires the officer to exercise judgement in the light of the circumstances in order to form a reasonable opinion that there has been a loss of tax and as to the amount of the tax loss.

[238]     This is clearly HMRC's own view. At paragraph 2030 of HMRC's Enquiry Manual, it sets out advice to its officers in raising discovery assessments and determinations as follows:

 “When a case comes before the tribunal you should at an early stage make sure that all assessments and determinations have been properly made for all years, including any necessary alternatives.

 You should always send a letter slightly in advance of the actual making of the assessments warning the taxpayer and agent of what you are doing, as well as stating that the assessments are to `prevent the loss of tax'. In an enquiry case the authority for raising assessments are TMA70/S29 or FA98/SCH18/Para41. Assessments must be to the best of your judgment. Information on which to base a judgment may be severely limited, but care should be taken in arriving at a figure, which will ideally be neither too low nor indefensibly high. Assessments must not be inflated grossly to try and frighten the taxpayer into co-operating or settling. Such tactics can, anyway, be self-defeating if the appeals come before the tribunal. If your estimates are ludicrously high the credibility of HMRC's case may be undermined. Your case will always be stronger if you can contend for confirmation of the amounts assessed rather than determination in lower figures.” (emphasis added)

[238]   And at EM3251:

 “Before an officer issues a discovery assessment they must first identify the quantum as accurately as possible to ensure that the correct amount of tax has been recovered.

However, there will be times when it is not possible to identify the quantum accurately. If this happens the officer can use their best judgment to calculate the amount of tax due and issue the assessment. Officers should keep a record of any reasonable inferences they make from the facts available at the time they make the assessment.” (Georgiou v. HMRC [2022] UKFTT 455 (TC), Judge McKeever)

Best judgement

Power to make discovery assessment

Income tax and CGT

"(1)     If an officer of the Board or the Board discover, as regards any person (the taxpayer) and a year of assessment—

(a)     that any income which ought to have been assessed to income tax, or chargeable gains which ought to have been assessed to capital gains tax, have not been assessed, or

(b)     that an assessment to tax is or has become insufficient, or

(c)     that any relief which has been given is or has become excessive,

the officer or, as the case may be, the Board may, subject to subsections (2) and (3) below, make an assessment in the amount, or the further amount, which ought in his or their opinion to be charged in order to make good to the Crown the loss of tax." (TMA 1970, s.29(1))

Amendment to deal with high income child benefit charge, gift aid and pensions charges

"(1)   In section 29 of TMA 1970 (assessment where loss of tax discovered), in subsection (1), for paragraph (a) substitute—

“(a) that an amount of income tax or capital gains tax ought to have been assessed but has not been assessed,”." (FA 2022, s.97, with retrospective effect for some assessments - see below)

Corporation tax

"(1)     If an officer of Revenue and Customs discovers as regards an accounting period of a company that—

(a)     an amount which ought to have been assessed to tax has not been assessed, or

(b)     an assessment to tax is or has become insufficient, or

(c)     relief has been given which is or has become excessive,

they may make an assessment (a “discovery assessment”) in the amount or further amount which ought in their opinion to be charged in order to make good to the Crown the loss of tax." (FA 1998, Sch 18, para 41(1))

SDLT

"(1)     If the Inland Revenue discover as regards a chargeable transaction that—

(a)     an amount of tax that ought to have been assessed has not been assessed, or

(b)     an assessment to tax is or has become insufficient, or

(c)     relief has been given that is or has become excessive,

they may make an assessment (a “discovery assessment”) in the amount or further amount that ought in their opinion to be charged in order to make good to the Crown the loss of tax." (FA 2003, Sch 10, para 28)

Discretion to assess

“We agree that there is nothing in paragraph 44 of the Schedule that specifically allows HMRC to suspend the imposition of penalties but, in our view, paragraph 46, by the use of the word “may”, allows them to do so. Paragraph 46 provides that HMRC have a discretion whether to assess a penalty and notify the person.” (Spring Capital Ltd v. HMRC [2017] UKUT 215 (TCC), §29, Judges Sinfield and Walters QC

More than one assessment possible in respect of the same tax year

 

“Nor do we consider that any assistance can be derived from the fact that more than one assessment may be made in respect of any given tax year.  In Cansick (Murphy’s Executor) v Hochstrasser (HM Inspector of Taxes) (1961) 40 TC 151, assessments for the years 1945-46 to 1947-48 had been made on the deceased taxpayer and discharged on appeal.  After an investigation additional assessments were made for those years.  It was argued for the taxpayer that only one additional assessment could be made and that the further assessments were therefore invalid.  That argument was rejected by Buckley J in the High Court.  Likewise in Vickerman (Inspector of Taxes) v Mason’s Personal Representatives [1984] STC 231, it was held that an assessment to recover tax which had been missed out of an earlier assessment by arithmetical error could be recovered by way of additional assessment.” (Clark v. HMRC [2017] UKFTT 392 (TC), §34, Judge Berner).
 

Power to make discovery assessment

- Discovery determination: corporation tax (error affects other company)

 

"(2)     If an officer of Revenue and Customs discovers that a company tax return delivered by a company for an accounting period incorrectly states—

(a)     an amount that affects, or may affect, the tax payable by that company for another accounting period, or

(b)     an amount that affects, or may affect, the tax liability of another company,

they may make a determination (a “discovery determination”) of the amount which in their opinion ought to have been stated in the return." (FA 1998, Sch 18, para 41(1))

- Discovery determination: corporation tax (error affects other company)

- Meaning of income which ought to have been assessed (previous law)

 

Does not mean amounts which ought to have been assessed to income tax

"[48] One way of avoiding the absurdity and injustice would be to read “income” as meaning “any amount liable to income tax” .  HMRC contend that this is the correct approach. The Respondent’s reasoning for seeking this interpretation is as a means of insuring other legislation has the benefit of that interpretation, however, we have not heard submissions on other legislation and for the purposes of this case, it is unnecessary for us to go beyond whether the legislation should be read in such a way as to make HICBC ‘income’ for the purposes of s29.  In addition the Tribunals in Wilkes and Haslam did consider the broader interpretation contended for by the Respondent, and we agree with their conclusion.  Neither Tribunal considered that this was an appropriate course for the reasons set out at paragraph 52(4) of Jason Wilkes..." (Box v. HMRC [2020] UKFTT 353 (TC), Judge Hudson)

Cannot be purposively interpreted to specifically include HICBC

"[50] In short, it seems to me that, were we to “rectify” section 29 of TMA 1970 as HMRC propose, we would be engaging in judicial legislation, not discharging our interpretative function. It may well be that, had Parliament considered the matter, it would have chosen to amend section 29 so as enable HMRC to make an assessment in respect of HICBC where no return had been delivered. However, we cannot be “abundantly sure” that that was Parliament’s intention, nor as to the substance of what Parliament would have enacted. I therefore consider that this ground of appeal fails." (HMRC v. Wilkes [2022] EWCA Civ 1612)

"[142] We do not think that the question of whether the principle in Inco Europe applies can be disassociated from the question of purposive construction. This is not just because both are principles of statutory interpretation. Rather, the underlying difficulty is what appears to have been an assumption by HMRC, possibly shared by the draftsperson of Schedule 1 to FA 2012, that s 29(1)(a) TMA was broad enough to catch “self-standing” income tax charges which are not charges on amounts of income. If, as we have held, that assumption was wrong on a purposive construction of the legislation, then it is very difficult to see how any error made by the draftsperson of Schedule 1 FA 2012 was the sort of slip that Lord Nicholls had in mind. This was not simply a case of Homer, in the shape of the draftsperson, having nodded (Inco Europe at p.589). Homer would have been under a material misapprehension." (HMRC v. Wilkes [2021] UKUT 150 (TCC), Falk J and Judge Herrington)

Current position

See the amendment made by FA 2022, s.97, above.

- Meaning of income which ought to have been assessed (previous law)

- Retrospective effect of amendment to s.29 for certain types of assessment​ (HICB, gift aid, pensions)

 

"(3)  The amendments made by this section—
(a)  have effect in relation to the tax year 2021-22 and subsequent tax years, and
(b)  also have effect in relation to the tax year 2020-21 and earlier tax years but only if the discovery assessment is a relevant protected assessment (see subsections (4) to (6))." (FA 2022, s.97(3))

Relevant protected assessment (HICB, gift aid, pensions)

"(4)  A discovery assessment is a relevant protected assessment if it is in respect of an amount of tax chargeable under—
(a)  Chapter 8 of Part 10 of ITEPA 2003 (high income child benefit charge),
(b)  section 424 of ITA 2007 (gift aid: charge to tax),
(c)  section 205 or 206 of FA 2004 (pensions) but only where the section is applied by Schedule 34 to that Act, or
(d)  section 208, 209, 214, 227 or 244A of FA 2004 (pensions), including where the section is applied by that Schedule." (FA 2022, s.97(4))

Discovery assessment

"(9) In this section—

“discovery assessment” means an assessment under section 29(1)(a) of TMA 1970" (FA 2022, s.97(9))

Not retrospective for appeals raising validity issue before July 2021

"(5)  But a discovery assessment is not a relevant protected assessment if it is subject to an appeal notice of which was given to HMRC on or before 30 June 2021 where—
(a)  an issue in the appeal is that the assessment is invalid as a result of its not relating to the discovery of income which ought to have been assessed to income tax but which had not been so assessed, and
(b)  the issue was raised on or before 30 June 2021 (whether by the appellant or in a decision given by the tribunal)." (FA 2022, s.97(5))

"[31] While this ground put forward on 3 May 2020 is a challenge to the validity of the 2015/16 assessment, I cannot interpret it as a challenge on the basis that the 2015/16 assessment was invalid as a result of its not relating to the discovery of income which ought to have been assessed to income tax but which had not been so assessed.  The Appellant does not mention income at all; instead, he is clearly arguing that he considers the 2015/16 assessment to be invalid because HMRC were, he considered, relying on an out of date and “stale” discovery, i.e., that the assessment was raised too late.  Or, put another way, what the Appellant is saying is “You raised this particular assessment too long after you had found out all about my tax affairs, the discovery was too long ago”." (Beales v. HMRC [2023] UKFTT 386 (TC), Judge Bailey)

Must be some express reference by the Appellant or Tribunal

"[55] I consider that s97(5)(b) must be interpreted in a manner which does not result in this sub-paragraph being redundant, such that it must mean something more than that required by s97(5)(a), and that the express reference in s97(5)(b) to the issue being raised either by the appellant or the tribunal means that there should be some express reference which can be identified as a challenge based on the Wilkes issue, even if that challenge is imprecise (or even, potentially, a slightly inaccurate description of the point in dispute in Wilkes).  For this reason, I prefer the approach taken in Hexstall to that in Fera.  I do not accept that any appeal against the assessments (other than one which accepts the principle but challenges the computation) “must inherently be challenging the validity of the assessment and that must involve…whether the elements of …[s29(1)(a)]… were satisfied” (at [44] of Fera).  I have concluded, having reviewed all documentary evidence of the communications between the parties before 30 June 2021 (which for this purpose includes Mr Burchett’s call to HMRC in January 2021, his appeal to HMRC in April 2021 and the representations to the reviewing officer in May 2021), that the Wilkes issue had not been raised by Mr Burchett on or before 30 June 2021.  The discovery assessments are not therefore excluded from being relevant protected assessments by s97(5)." (Burchett v. HMRC [2024] UKFTT 121 (TC), Judge Zaman)

Cannot rely on HMRC's statement of case

"[28] The Appellant has argued that I should interpret HMRC’s summary of his grounds of appeal as demonstrating that HMRC understood him to be making a challenge that falls within the meaning of Section 97(5)(a) in respect of the assessments raised upon him.  However, as I have noted above, for an issue to fall within Section 97(5)(a), it must be an issue raised either by the Appellant or by the Tribunal.  The relevant text to be considered is what appears in the Appellant’s own letters and emails, not the responses sent by HMRC." (Beales v. HMRC [2023] UKFTT 386 (TC), Judge Bailey)

Not retrospective for appeals stayed before 27 October 2021 to address validity issue

"(6)  In addition, a discovery assessment is not a relevant protected assessment if—
(a)  it is subject to an appeal notice of which was given to HMRC on or before 30 June 2021,
(b)  the appeal is subject to a temporary pause which occurred before 27 October 2021, and
(c)  it is reasonable to conclude that the temporary pausing of the appeal occurred (wholly or partly) on the basis that an issue of a kind mentioned in subsection (5)(a) is, or might be, relevant to the determination of the appeal." (FA 2022, s.97(6))

 

"(8) For the purposes of this section an appeal is subject to a temporary pause which occurred before 27 October 2021 if—(a) the appeal has been stayed by the tribunal before that date,(b) the parties to the appeal have agreed before that date to stay the appeal, or(c)  HMRC have notified the appellant (“A”) before that date that they are suspending work on the appeal pending the determination of another appeal the details of which have been notified to A." (FA 2022, s.97(8))

 

"[66] I have decided that Mr Burchett’s appeal was not subject to a temporary pause which occurred before 27 October 2021.  I was not satisfied that HMRC and Mr Burchett had agreed before that date to stay the appeal, nor that HMRC had notified him that they were suspending work on the appeal pending determination of Wilkes." (Burchett v. HMRC [2024] UKFTT 121 (TC), Judge Zaman)

Notified

“notified” means notified in writing." (FA 2022, s.97(9))

Time of notice of appeal

"(7)  For the purposes of this section the cases where notice of an appeal was given to HMRC on or before 30 June 2021 include a case where—
(a)  notice of an appeal is given after that date as a result of section 49 of TMA 1970, but
(b)  a request in writing was made to HMRC on or before that date seeking HMRC’s agreement to the notice being given after the relevant time limit (within the meaning of that section)." (FA 2022, s.97(7))

- Retrospective effect of amendment to s.29 for certain types of assessment​ (HICB, gift aid, pensions)

Meaning of discover

Meaning unchanged by move to self-assessment 

 

“Although the conditions under which a discovery assessment can be made have been tightened in recent years following the introduction of the self-assessment regime, the meaning of the word 'discovers' in this context has not changed.” (Hankinson v. HMRC [2011] EWCA Civ 1566, §15).

 

“although the concept of “discovery” is carried over from the regime which applied before self-assessment, and still has the same wide meaning as before, the circumstances in which a discovery assessment may be made are now much more circumscribed…” (HMRC v. Household Estate Agents Ltd [2007] EWHC 1684 (Ch), §29(c)).

 

“It would be surprising, given the well-known interpretation of the word "discover" under the pre-self-assessment rules, if Parliament had intended that the same word should have a different meaning for the purposes of self-assessment. It would be expected that Parliament would have made such a change clear, but it did not do so.” (Blumenthal v. HMRC [2012] UKFTT 497 (TC), §159).

Meaning of discover

- General

“We consider that case law has shown that to be a ‘discovery’ within s 29 HMRC must prove the following (see Atherton [2017] UKFTT 831 (TC) at §206-218):
(a)    An HMRC officer has crossed a threshold from non-awareness to awareness of an insufficiency;
(b)   He acted reasonably when so doing;
(c)    HMRC as a body did not previously have the awareness of the insufficiency;
(d)   The assessment must be proximate to the discovery.” (Vowles v. HMRC [2017] UKFTT 704 (TC), §67, Judge Mosedale).

- General

- Discovers means “finds” or “satisfies himself” or "newly appears"

 

“In R v Comrs for the General Purposes of Income Tax for Kensington (1913) 6 TC 279 at 283, Bray J said that it meant 'comes to the conclusion from the examination he makes and from any information he may choose to receive' and Lush J said that it was equivalent to 'finds' or 'satisfies himself' (1913) 6 TC 279 at 290…” (Hankinson v. HMRC [2011] EWCA Civ 1566, §15).

 

“The word “discover” in section 19 does not mean “ascertain by legal evidence” but mean simply that the officer comes to his conclusion from the examination he makes and information which he receives…” (Martin v. HMRC [2015] UKUT 0161 (TCC), §31).

 

“The word “discovers” has a long history: it means that the officer “finds”, or “satisfies himself”, or that “it newly appears” to him, that there has been an undercharge; it is not necessary that the officer has discovered some new facts.” (Hargreaves v. HMRC [2014] UKUT 395 (TCC), §21(1)).

- Discovers means “finds” or “satisfies himself” or "newly appears"

- Information points in the direction of insufficiency (not more likely than not)

 

"[28] In Sanderson, Patten LJ described the power under section 29(1) in this way:

“The exercise of the section 29(1) power is made by a real officer who is required to come to a conclusion about a possible insufficiency based on all the available information at the time when the discovery assessment is made.”

We consider, with respect, that this test is in accordance with the earlier authorities. This passage describes the test somewhat briefly because, of course, that case concerned s 29(5) rather than s 29(1). Having reviewed the authorities, we consider that it is helpful to elaborate the test as to the required subjective element for a discovery assessment as follows:

“The officer must believe that the information available to him points in the direction of there being an insufficiency of tax.”

That formulation, in our judgment, acknowledges both that the discovery must be something more than suspicion of an insufficiency of tax and that it need not go so far as a conclusion that an insufficiency of tax is more probable than not." (Anderson v. HMRC [2018] UKUT 159 (TC), Morgan J and Judge Berner)

- Information points in the direction of insufficiency (not more likely than not)

Discovery refers to subjective view of officer

“That s 29(1) is dealing with the subjective views of the officer concerned is borne out by the consequence of the making of a discovery viz that he may make an assessment of the amount 'which ought in his … opinion' to be charged to make good the loss of tax.” (Hankinson v. HMRC [2011] EWCA Civ 1566, §17).

 

“It may be that he was slower and more cautious about forming this view than some other HMRC officers might have been, but it is his characteristics which matter for this purpose, not those of other officers. I see no reason to question the FTT’s judgment on this point.”  (Pattullo v. HMRC [2016] UKUT 270 (TCC), §62, Lord Glennie).

 

“s. 29(1) is concerned with the officer's subjective views…” (Hargreaves v. HMRC [2014] UKUT 395 (TCC), §21(1)).

 

 “… the first preliminary part of the test is no more than an assertion by the officer of a newly discovered insufficiency.” (R (oao Pattullo) v. HMRC [2009] CSOH 137, §104).

- Discovery refers to subjective view of officer

- Does not require discovery of new facts/includes discovery of new legal analysis 

 

“I can see no reason for saying that a discovery of undercharge can only arise where a new fact has been discovered. The words are apt to include any case in which for any reason it newly appears that the taxpayer has been undercharged, and the context supports rather than detracts from this interpretation.” (Cenlon Finance Co Ltd v. Ellwood 40 TC 176 at 204, Viscount Simonds with whom Lord Reid agreed)

 

“It is a mistake to say that everyone is presumed to know the law. The true proposition is that no one is to be excused from doing his duty by pleading that he did not know the law. Every lawyer who, in his researches in the books, finds out that he was mistaken about the law, makes a discovery. So also does an Inspector of Taxes.” (Cenlon Finance Co Ltd v. Ellwood 40 TC 176 at 207, Lord Denning)

 

“Of course, if there were any reason in the context for restricting the word 'discover' to the discovery of an error in face that restriction would necessarily receive effect, but in my opinion the context points, not to any such restriction, but, on the contrary, to so wide a meaning that the word ought to be held to cover just the kind of discovery which was made here, when the Special Commissioners found out that, by reason of a misapprehension of the legal position, certain of the profits chargeable to tax had been omitted from the first assessment.” (CIR v. Mackinlay’s Trustees 22 TC 305 at 313).

 

Equally applicable to mistakes as to the general law as to mistaken interpretations of a document 

 

“…although it is true that in that case he may not have been dealing with a mistake in the general law of the country as distinct from a mistake in the interpretation of a document. the case was rather on the border line. He was dealing with the proper application of Section 20 of the Income Tax Act, 1918, to the provisions of the particular deed to the exclusion of clause 15. But however that may be, I think the language of Lord Normand is applicable, and the reasoning is equally applicable to mistakes made with regard to the general law or rather, I should say, to the discovery of the effect of the general law upon a particular set of facts.” (Commercial Structures v. Briggs 30 TC 477 at 493).

 

Includes discovery based on “change” in law as a result of judicial decision 

 

“It is true that the result of this construction of Section 125 may of necessity, in some cases involve the taxpayer in the hardship that assessments made some years back may be affected or upset by additional assessments made in the light of some subsequent decision, perhaps of the House of Lords, but, none the less. I think that this is the proper construction of the Section.” (Commercial Structures v. Briggs 30 TC 477 at 493).

 

Arithmetical error in assessment 


“Simply as a matter of language, it seems to me that that provision covers, inter alia, an arithmetical error in the computation of tax. In such a case, I would have thought, the situation would be one where the assessment to tax was insufficient by reason of that error.” (Vickerman v. Mason’s Personal Representatives [1984] STC 231 at 234 ).
 

- Does not require discovery of new facts/includes discovery of new legal analysis 

- Not required to resolve every possible dispute
 

“Nor does s 29(1) require the officer to have considered every possible legal argument or to have resolved every possible dispute; the remarks of the Chancellor (Sir Andrew Morritt) in Revenue and Customs Commissioners v Lansdowne Partners Ltd Partnership [2012] STC 544, although directed towards the assumed awareness of the hypothetical officer in s 29(5), are in our view equally apt to describe the opinion of the actual officer for the purpose of s 29(1).” (Clark v. HMRC [2017] UKFTT 392 (TC), §15, Judge Berner).

- Not required to resolve every possible dispute

- Discovery may be a process

 

“The process of discovery, or coming to a realisation, or forming a view, whichever expression one chooses, is not always as simple as is suggested by the metaphor of crossing a threshold. There may be moments when the discovery of new information causes an inspector briefly to form a view that more tax is owing than has been assessed. But then he may reflect that perhaps he has been overhasty in coming to that conclusion, perhaps he needs more information, one more piece of the jigsaw. This may happen a number of times. It may not always involve the acquisition of further information. It may involve legal research, or further reflection on the legal research already carried out. Or it may simply be a question of taking more time to think; of lights coming on one by one until eventually it becomes clear; of weighing the matter up, sometimes coming to one view and sometimes another, until eventually coming down on one side or another. There is, to my mind, some force in Mr Anderson’s point about the danger of analysis by metaphor, but if the metaphor of crossing the threshold is to be used, then, while that moment may occur at the end of that process, there will be many points on the way to that threshold when discoveries are made, points become clearer and thoughts become more refined. There may even be hesitation on the doorstep, shifting forwards then back again before finally going in.” (Pattullo v. HMRC [2016] UKUT 270 (TCC), §44, Lord Glennie).

- Discovery may be a process

​- Difficult to challenge assertion of discovery

 

“[The taxpayer] described [s.29(1)] as a “loose and wobbly” provision, by which I understood him to mean that it is difficult in practice to challenge an officer's assertion that he has come to the view that there has been an undercharge.” (Hargreaves v. HMRC [2014] UKUT 395 (TCC), §21(1)).

​- Difficult to challenge assertion of discovery

Officer can re-discover what HMRC have already discovered

 

"[57] Of course (as the Supreme Court held in Tooth at [78] and [82]) it is entirely possible that the discovery made by Mr Pollitt could subsequently be made (again) by another HMRC officer. In such a case, the other HMRC officer could then raise the s29(1) assessment." (Brown v. HMRC [2024] UKFTT 245 (TC), Judge Aleksander)

However: 

“Mr Ashby’s discoveries do not matter if preceded by earlier discoveries made by others in HMRC, and in particular by Ms Naish, who was the officer who had previous responsibility for the investigation into Ms Vowles.  Mr  Ashby’s evidence did not make clear what was known to Ms Naish and when:  and it seems from the dates in the previous paragraph that Ms Naish could have discovered in mid-2012 the discrepancies which Mr Ashby assessed in November 2013.  HMRC have not satisfied the Tribunal, therefore, that the discovery took place later than mid-2012.” (Vowles v. HMRC [2017] UKFTT 704 (TC), §71, Judge Mosedale).

- Officer cannot re-discover HMRC have already discovered

Opinion of discovery must be reasonable

 

"[24]...We consider that the following propositions are now established by the various authorities: 

(1) s 29(1) refers to an officer (or the Board) discovering an insufficiency of tax;

(2) the concept of an officer discovering something involves, in the first place, an actual officer having a particular state of mind in relation to the relevant matter; this involves the application of a subjective test;

(3) the concept of an officer discovering something involves, in the second place, the officer’s state of mind satisfying some objective criterion; this involves the application of an objective test;

(4) if the officer’s state of mind does not satisfy the relevant subjective test and the relevant objective test, then the officer’s state of mind is insufficient for there to be a discovery for the purposes of subsection (1);

(5)  s 29(1) also refers to the opinion of the officer as to what ought to be charged to make good the loss of tax; accordingly, the officer has to form a relevant opinion and such an opinion has to satisfy some objective criterion;

...

[29] The authorities establish that there is also an objective test which must be satisfied before a discovery assessment can be made. In R v Bloomsbury Income Tax Commissioners, the judges described the objective controls on the power to make a discovery assessment. Those controls were expressed by reference to the principles of public law. In Charlton at [35], the Upper Tribunal referred to the need for the officer to act “honestly and reasonably”. 

[30] The officer’s decision to make a discovery assessment is an administrative decision. We consider that the objective controls on the decision making of the officer should be expressed by reference to public law concepts. Accordingly, as regards the requirement for the action to be “reasonable”, this should be expressed as a requirement that the officer’s belief is one which a reasonable officer could form. It is not for a tribunal hearing an appeal in relation to a discovery assessment to form its own belief on the information available to the officer and then to conclude, if it forms a different belief, that the officer’s belief was not reasonable." (Anderson v. HMRC [2018] UKUT 159 (TCC), Morgan J and Judge Berner)

“HMRC have a duty to exercise due care and diligence and come to a bona fide belief as to the amount of tax chargeable.” (HMRC v. Rogers [2009] EWHC 3433 (Ch), §19).

"[201] We consider that Mrs Morritt’s belief that Mr Batten’s liability to tax had been understated as a result of discovering the cessation of his full-time employment overseas was a reasonable one for her to make for the following reasons. 

...

[204] The fact that Mr Batten had ceased to be employed full-time overseas was therefore highly material to his residence position, albeit not determinative." (Batten v. HMRC [2022] UKFTT 199 (TC), Judge Bowler)

 

“The amount assessed must be based on known facts or on reasonable inferences drawn from known facts so that it can be said to be ‘fair’ (see Johnson v Scott (1978) 52 TC 383 per Walton J at 394, approved by the Court of Appeal at 403).” (Hull City AFC (Tigers) Ltd v. HMRC [2017] UKFTT 629 (TC), §71, Judge Gammie QC).

 

“The core of the Appellant’s case is that whatever Ms Lampard knew about the Bafana arrangements and the other participants in the Bafana Scheme, she did not know enough about Mr Anderson’s own involvement in the scheme to have a reasonable belief that he had been under-assessed for the 2008-9 tax year…The Appellant says that the discovery assessment was based on a suspicion not a belief.  A suspicion becomes a belief when it is based on logical conclusions derived from what is known. Our view is that even on the basis that all HMRC knew in early May 2012 was that the Bafana Scheme existed, that it was an orchestrated scheme, that its participants included Mr Anderson and that the scheme  had implementation issues, that was sufficient to form the basis of a “reasonable belief” that there had been an under-assessment. It was a reasonable and logical conclusion on the basis of what HMRC knew about the Bafana Scheme and Mr Anderson’s participation in it, that Mr Anderson had claimed losses derived from the scheme to which he was not entitled.” (Anderson v. HMRC [2016] UKFTT 565 (TC), §§65 – 66).

Opinion of discovery must be reasonable

- Failing to consider relevant explanations and evidence

 

"[52] There are also a number of relevant factors which the officer does not seem to have considered when reaching his conclusion. The fact that the RTI records showed that employees had been paid at the end of August, but no such payment had been made from the bank account. The logical conclusion was that it reflected cash which had not been banked. The fact that the appellant or its members had accounted for VAT and income tax on the additional takings. The fact that both the partnership accounts and the LLP balance sheet showed an increase in cash in hand. An analysis of the purchases which suggests that they supported the supply of meals to a greater extent than the additional £56,000 or so accepted by the officer as evidenced by credit card receipts.

[53] None of these matters is conclusive. Indeed, as Mr Ellis suggests, there may be explanations for them which are consistent with any additional cash having been received on non-scheme days. But none of them seems to have been considered, let alone discounted, by Officer Maddison when reaching his conclusion.

[54] He seems to have come to the decision that in the absence of dated and timed bills, there was nothing that the appellant could do to justify the additional cash takings. He did not seriously consider any other matters which could have supported the claim. And so he failed to consider the relevance of those other matters.

[55] For these reasons we do not consider that Officer Maddison arrived at an objectively reasonable opinion, on the basis of the information available to him, that the appellant had overclaimed an amount of support payment. And we therefore allow its appeal." (Cafe Jinnah LLP v. HMRC [2024] UKFTT 159 (TC), Judge Popplewell)

- Failing to consider relevant explanations and evidence

- Ascertaining an irrelevant matter is not discovery 
 

“It seems to me the learned Judge was there holding that the fact that the company in subsequent years had given further credit to those debtors was a matter irrelevant to be taken into consideration in ascertaining whether or not the debt was a bad debt several years earlier.” (Commercial Structures v. Briggs 30 TC 477 at 489 in relation to Halstead Ltd v. Birrell 16 TC 200).

[205] We can conceive of situations where a highly relevant factor is discovered but further discussions with the taxpayer and/or their advisers means that in fact it would not be reasonable to conclude that the factor meant that the taxpayer’s liability to tax had been under assessed.  The relevant issue then is the reasonableness of a subsequent discovery assessment raised by an HMRC officer, not whether a relevant discovery had been made.  However, that is not the situation here for the reasons we have explained." (Batten v. HMRC [2022] UKFTT 199 (TC), Judge Bowler)
 

- Ascertaining an irrelevant matter is not discovery 

Individual officer must make discovery (not a team)

 

"[50] This provision was considered in detail by the Supreme Court in HMRC v Tooth [2021] UKSC 17. At [68] the Supreme Court held that the provision operates by reference to the state of mind of a particular officer of HMRC, and not collective knowledge on the part of HMRC.

[51] We note in HMRC's manuals at EM3231 it says:

A discovery must be made by an individual officer. A discovery cannot be made by 'HMRC' or by a 'team' within HMRC."

We agree.

...

[62] Although Ms Aziz did not raise the possible application of s103(1) Finance Act 2020 in her submissions, we have considered whether it might apply to a discovery assessment. Section 103(1) provides that anything capable of being done by an officer of HMRC may be done by HMRC (including by means of a computer). Section 103(2) then goes on to list various provisions to which s103(1) can apply. This list is plainly not exhaustive, but it is interesting to note that although the list includes various provisions of TMA (including s30A), it does not include s29(1). We consider that the omission is deliberate, as the making of a discovery (and any consequential assessment) under s29 is evaluative, and must necessarily relate to the state of mind of an individual officer, rather than of "HMRC" as a collective entity. We find that s103(1) cannot apply to discovery assessments made under s29." (Brown v. HMRC [2024] UKFTT 245 (TC), Judge Aleksander)

Individual officer must make discovery (not a team)

- Discovering officer must make the assessment 

 

"[52] The drafting of s29(1) provides that if "an officer" makes a discovery, "the officer" may make an assessment. The use of the definite article carries with it the implication that where an HMRC officer makes a discovery, the power to make an assessment in respect of the discovery lies with that same officer, and (subject to what we say below in relation to s2(4) Commissioners of Revenue and Customs Act 2005) with no one else - and we so find." (Brown v. HMRC [2024] UKFTT 245 (TC), Judge Aleksander)

- Discovering officer must make the assessment 

- But may delegate sending the letter to another officer

 

"[135] [The taxpayer] points to the fact that while HMRC’s evidence was from Ms Frusher, the officer whose name appeared on the assessment was Sundri Felix and that Ms Frusher did not give any evidence about delegating the issuing of the assessment to Ms Felix. It is submitted the FTT failed to address the discovery question and made no determination of the issue. HMRC highlight the issue regarding the different officer name was only raised after the evidence had closed and that Ms Frusher was not cross-examined on the point.

[136] We agree with [HMRC's] submissions that Ms Frusher’s evidence, given on behalf of HMRC, was sufficient to prove 1) she had made a discovery and 2) that she had made the assessment.

[137] In the absence of any challenge regarding whether someone else had made the assessment, we consider it was open to the FTT to accept that evidence despite someone else’s name appearing on the assessment letter of the same date. The date of that letter (31 March), the same date Ms Frusher says she made the particular assessment, is entirely consistent with Ms Frusher delegating the sending of the actual letter to another officer (which is endorsed by s113(IB) TMA[5] and in the case-law (Burford v Durkin [1991] STC 7)). Where one officer gives evidence they have made the assessment, but a different officer’s name appears on the letter in which the assessment is sent, and there is no inconsistency with the legal framework regarding the issue by one officer of an assessment a different officer has made, there is no presumption that the evidence must set out that the issue of the assessment which the first officer had made was delegated to another officer." (HFFX LLP v. HMRC [2023] UKUT 73 (TCC), Mellor J and Judge Raghavan)

"[57]...We also recognise that an officer making an assessment under s29(1) can legitimately delegate the administrative task of notifying the assessment to the taxpayer to someone else within HMRC." (Brown v. HMRC [2024] UKFTT 245 (TC), Judge Aleksander)

- But may delegate sending the letter to another officer

- Or a new officer continue process begun by other officer

"(4) Anything (including anything in relation to legal proceedings) begun by or in relation to one officer of Revenue and Customs may be continued by or in relation to another." (CRCA 2005, s.2(4))

"[60] In other words, s2(4) would allow Mr Pollitt to begin the consideration of a case, making the discovery under s29(1) TMA, and then passing the case on to another officer to complete the exercise by making an assessment." (Brown v. HMRC [2024] UKFTT 245 (TC), Judge Aleksander)

- Or a new officer continue process begun by other officer

- Assessment invalid if not shown that officer who made assessment also made discovery or took over file from discovering officer

 

"[58]  However, in the circumstances of this case, we have no evidence as to the officer within HMRC who made the s29(1) assessment, and whether they made the assessment following their own "refreshed" discovery of Mr Brown's liability to HICBC.

...

[61] The only evidence before us relating to the making of the s29(1) assessment is the letter notifying Mr Brown of the assessment - which was signed by the "HICBC Team". We note that HMRC in their manuals state that an assessment under s29 cannot be made by a team, but only by an individual officer of HMRC (or the HMRC Board acting as such) - which is consistent with the Supreme Court's decision in Tooth. We have no evidence before us as to the circumstances under which the s29(1) assessment was made, and in particular whether the assessment was made by an identifiable individual officer, and whether he made a fresh discovery himself, or whether he took over Mr Brown's file from Mr Pollitt in exercise of the powers in s2(4) Commissioners of Revenue and Customs Act 2005.

...

[64] The onus of proof falls on HMRC to demonstrate that the requirements relating to the making of an assessment under s29(1) have been met. In the absence of any evidence about the officer who made the s29(1) assessment, they have failed to do so in this case, and we find that they have failed to meet the burden of proof that the assessments were validly made." (Brown v. HMRC [2024] UKFTT 245 (TC), Judge Aleksander)

- Assessment invalid if not shown that officer who made assessment also made discovery or took over file from discovering officer

Stale discoveries

 

"[76] In our judgment, contrary to the latter part of para 37 in the decision in Charlton, there is no place for the idea that a discovery which qualifies as such should cease to do so by the passage of time. That is unsustainable as a matter of ordinary language and, further, to import such a notion of staleness would conflict with the statutory scheme. That sets out a series of limitation periods for the making of assessments to tax, each of them expressed in positive terms that an assessment “may be made at any time” up to the stated time limit." (HMRC v. Tooth [2021] UKSC 17)

Stale discoveries

Valid assessment in respect of one matter cannot include another matter in the same tax year that could not be assessed separately

“There is in our view a further limitation on the scope of a discovery assessment.  It cannot extend to, and likewise an appeal against it cannot provide jurisdiction on the Tribunal in relation to, a loss of tax for which no valid assessment was capable of being made by reason of a specific prohibition under s 29, for example because that particular loss of tax was one of which the hypothetical officer in s 29(5) could have been reasonably expected to have been aware.  Thus, to adopt the example given by Mr Jones, if Loss of Tax A was precluded from being assessed under s 29, a discovery of Loss of Tax B, even in circumstances where Loss of Tax A could, on the basis we have outlined, fall within the scope of the assessment in relation to Loss of Tax B, it will not do so by virtue of s 29 itself.” (Clark v. HMRC [2017] UKFTT 392 (TC), §24, Judge Berner).

Valid assessment in respect of one matter cannot include another matter in the same tax year that could not be assessed separately

No discovery assessment if return in accordance with practice generally prevailing

Income tax and CGT

"(2)     Where—

(a)     the taxpayer has made and delivered a return under section 8 or 8A of this Act in respect of the relevant year of assessment, and

(b)     the situation mentioned in subsection (1) above is attributable to an error or mistake in the return as to the basis on which his liability ought to have been computed,

the taxpayer shall not be assessed under that subsection in respect of the year of assessment there mentioned if the return was in fact made on the basis or in accordance with the practice generally prevailing at the time when it was made." (TMA 1970, s.29(2))

Corporation tax

"No discovery assessment for an accounting period for which the company has delivered a company tax return, or discovery determination, may be made if—

(a)     the situation mentioned in paragraph 41(1) or (2) is attributable to a mistake in the return as to the basis on which the company's liability ought to have been computed, and

(b)     the return was in fact made on the basis or in accordance with the practice generally prevailing at the time when it was made." (FA 1998, Sch 18, para 45 - read with para 42, below)

SDLT

"(5)     No assessment may be made if—

(a)     the situation mentioned in paragraph 28(1) or 29(1) is attributable to a mistake in the return as to the basis on which the tax liability ought to have been computed, and

(b)     the return was in fact made on the basis or in accordance with the practice generally prevailing at the time it was made." (FA 2003, Sch 10, para 30)

Burden on taxpayer to demonstrate error and generally prevailing practice 

 

“The burden of proving the existence of the error and a generally prevailing practice rests on the taxpayer.” (Hankinson v. HMRC [2011] EWCA Civ 1566, §19).

 

“…it seems clear to me as a matter of general principle that the burden of proof must rest on the party who asserts that there has been an operative mistake in the return, and that the return was in fact made in accordance with the generally prevailing practice. That party will inevitably be the taxpayer, not HMRC. In other words, the burden lies on the taxpayer to establish that para 45 [of FA 1998, Sch 18] applies, not on HMRC to establish that it does not apply.” (HMRC v. Household Estate Agents Ltd [2007] EWHC 1684 (Ch), §45, query whether the result is the same for TMA 1970 s.29(2)).

 

Error relates to the undercharge not the discovery 

 

“ ‘the situation mentioned in subsection (1)’ is the fact that there has been an undercharge, not the officer's discovery of that fact. It makes sense to say that the undercharge is attributable to an error in the return; it makes no sense to say that the officer's discovery of the undercharge is attributable to the error in the return.” (Hargreaves v. HMRC [2014] UKUT 395 (TCC), §21(3)).

Prevailing practice must be sufficiently precise

 

“A practice within para 45(b) must be capable of being readily ascertained; otherwise it could not be one that was capable of general acceptance. And in order to be readily ascertainable, the practice must have substance (in the sense of not being inchoate), and be sufficiently precise and devoid of uncertainty as to its application. In particular, such a practice would not exist if it was equivocal or dependent on the ascertainment of facts, except where the criteria for its application by reference to the facts were themselves understood with a sufficient degree of precision so as the make the practice one that can be readily applied in any given case.” (Boyer Allan Investment Services Ltd v. HMRC [2012] UKFTT 558 (TC), §34).

 

Prevailing practice must be long-established, readily ascertainable, and accepted by HMRC and taxpayers 

 

“Without attempting to give an exhaustive definition, it seems to me that a practice may be so described only if it is relatively long-established, readily ascertainable by interested parties, and accepted by HMRC and taxpayers' advisers alike…” (HMRC v. Household Estate Agents Ltd [2007] EWHC 1684 (Ch), §58).

 

“The same quality of clarity and precision must be present in the understanding of HMRC and taxpayers and their advisers alike. It is not enough that an interested party be able to ascertain from HMRC what its approach to a particular issue might be. It must be possible to demonstrate that the same answer to the enquiry would be given by the broad community of tax professionals engaged in a particular area.” (Boyer Allan Investment Services Ltd v. HMRC [2012] UKFTT 558 (TC), §38).

 

“We construe s 29(2) as a protection to the taxpayer from an assessment where the Revenue have changed their mind on a doubtful point in a sense adverse to the taxpayer. It would in our judgment go too far to construe it, as [the taxpayer] urged us to do, as a bar on the Revenue from raising a discovery assessment in particular circumstances where they had not publicly adopted a practice. We agree that a practice generally prevailing has to be a practice, or agreement, or acceptance over a long period whereby the Revenue agreed or accepted a certain treatment of sums in particular circumstances. In the circumstances of this case, for there to have been such a practice, the Revenue would have had to have agreed or accepted that a consideration such as that received by the appellant from Fortuna was to be treated for tax purposes as having been capital and not income. There was no evidence of such a practice.” (Rafferty v. HMRC [2005] STC (SCD) 484, §114).

 

Unnecessary to agree legal basis for practice

 

“We agree that if there is a sufficiently precise practice that is adopted and followed by both taxpayers as a general matter and HMRC, then the underlying rationale for any particular party deciding to adopt such a practice, or to act or omit to act, is not relevant. What matters is that there is a mutual understanding to proceed in a particular way in particular defined circumstances. There does not need to be an identical thought process on all sides in arriving at the settled practice.” (Boyer Allan Investment Services Ltd v. HMRC [2012] UKFTT 558 (TC), §42).

 

Practice of not taking a particular point/argument requires the prior identification of that point

 

There is a distinction between a practice that particular amounts are deductible for tax purposes, which necessarily includes the practice of not taking any argument in favour of non-deductibility (identified or unidentified), and a situation where HMRC’s view on deductibility is unsettled, but there is a settled practice of not raising a particular argument in favour of non-deductibility. In the latter case a practice can only arise if the point or argument has first been identified by HMRC.

 

“A practice not to take a particular point, therefore, must have as its foundation the identification of that issue before the practice is adopted.  Merely failing to take a point is not enough, as the taxpaying community would not be able to discern anything as a matter of practice from such an omission.” (Boyer Allan Investment Services Ltd v. HMRC [2012] UKFTT 558 (TC), §107).

 

Required longevity related to manner of communication

 

“A new practice that is published will be unlikely, in our view, to require the same degree of longevity as might be required for an unpublished practice. Although each case will depend on its own facts we can envisage that an unpublished practice of the Revenue might take longer to seep into the collective consciousness of tax advisers generally.” (Boyer Allan Investment Services Ltd v. HMRC [2012] UKFTT 558 (TC), §36).

 

Publication of practice unnecessary

 

“But publication is not a necessary ingredient. A practice, albeit unpublished, will be equally ascertainable if it can be readily discovered from enquiry of HMRC themselves or from advice sought from a practitioner in the field, particularly where the practice arises in a specialised area.” (Boyer Allan Investment Services Ltd v. HMRC [2012] UKFTT 558 (TC), §35).

 

Not opening enquiries can be evidence of practice

 

“The failure to open an enquiry can obviously be based on a settled practice; indeed that would be a most likely outcome of the application of such a practice.” (Boyer Allan Investment Services Ltd v. HMRC [2012] UKFTT 558 (TC), §113).

 

Practice by custom/usage

 

“It is of course the case that, in order to be generally prevailing, the practice must have been capable of being identified by taxpayers when making their returns (although it is not necessary that a taxpayer has identified the practice). An internal practice adopted by HMRC, however precise in its terms, will not be generally prevailing until such time as it can be identified with sufficient precision by taxpayers and their advisers. We do not consider that communication as such is required. As custom can arise by usage, so too a practice can become generally prevailing merely by general adoption, irrespective of any actual communication. But there must still be the necessary quality of precision in the manner in which the practice is generally adopted and applied.” (Boyer Allan Investment Services Ltd v. HMRC [2012] UKFTT 558 (TC), §37).


Practice by mere inactivity

 

“We consider that mere inactivity can, in appropriate circumstances, give rise to a practice. This may be the product of a conscious response to a particular issue or a defined set of circumstances, or it may simply arise as a result of repetition of an omission to act in a different way, provided that the omission to act is based on a consideration of the issue, such as the applicability of a relevant statutory provision, or of the circumstances. But such an omission must also be capable of articulation in the same way as a positive act. It must have both clarity and substance. Its parameters must be clearly defined so that the general acceptance amounts to the same unequivocal understanding.” (Boyer Allan Investment Services Ltd v. HMRC [2012] UKFTT 558 (TC), §41).
 

No discovery assessment if return in accordance with practice generally prevailing

- Taxpayer does not need to know it was the practice generally prevailing

 

"[63]...A taxpayer might expressly invoke a particular PGP in a tax return or have it expressly in mind when making that return. Such a taxpayer would be making a return “on the basis of” the PGP. A different taxpayer might not expressly invoke a PGP and might not even be aware of it when preparing a return. However, that taxpayer’s return might nevertheless be “in accordance with” the terms of that PGP if it complied with the requirements of the PGP. The word “or” ensures that both taxpayers are entitled to the benefit of s29(2)." (Hargreaves v. HMRC [2022] UKUT 34 (TCC, Edwin Johnson J and Judge Jonathan Richards)

- Taxpayer does not need to know it was the practice generally prevailing

- Nature of HMRC's checks on returns do not prove practice

 

"[70] We have already explained, in paragraph [64] above, why we reject Mr Hargreaves’ argument that there was a PGP as to the “submission” of returns that stood separate from the practice HMRC employed in scrutinising them. In a similar vein, we reject Mr Hargreaves’ argument that HMRC’s practice in checking returns demonstrated that there was a PGP to the effect that claims to non-residence based on day-count would inevitably be accepted. It was a relevant factor, and one that the FTT had in mind because the FTT referred to HMRC checks of self-assessment returns at [40] of the Decision. However, the nature of HMRC’s checks was certainly not dispositive. Even if there was no PGP, so that all claims to residence fell to be determined by application of a multi-factorial assessment, it would still make sense for HMRC to identify obviously debatable cases by considering whether the day-counts set out in IR20 had been exceeded." (Hargreaves v. HMRC [2022] UKUT 34 (TCC, Edwin Johnson J and Judge Jonathan Richards)

- Nature of HMRC's checks on returns do not prove practice

- Can be based on HMRC's guidance, but T must have acted fully in accordance with guidance

 

"[147] It was argued for the appellant that the best evidence of HMRC's practice was the contemporaneous guidance and publications such as the documentation produced by AMPS. I agree primarily because there was very little other evidence. As can be seen, Mr Last’s evidence was very scant and amounted to saying that his predecessor had spoken to others in the industry.

...

[155] I agree with Mr Platnauer that in the Relevant Years HMRC did not have a policy or practice of accepting that the transfer of an asset would be a “contribution paid” under the legislation where it simply followed an offer to pay a monetary amount. On the contrary HMRC have set out clearly in both versions of the 2009 guidance that that was not sufficient to achieve a monetary contribution. A debt had to be created and there had to be agreement between the Scheme Administrator and the employer before there was any off set.

[156] Furthermore, there should not be any material difference between the valuations. As can be seen from the AMPS documentation that had been discussed with the industry representatives at some length in the period 2007 to 2009 (see in particular paragraphs 46, 49 and 51 above).

[157] On the facts found the appellant did not implement the three step process in the manner set out either in the 2009 Guidance or as recorded in the AMPS documentation." (Killik & Co LLP v. HMRC [2023] UKFTT 653 (TC), Judge Anne Scott)

- Can be based on HMRC's guidance, but T must have acted fully in accordance with guidance

- Exception only applies to self assessment return (not certain pensions issues)

 

"[130] I agree with [HMRC] that there is nothing absurd in those provisions applying only in the context of self-assessment. Those who drafted Reg.14 did not need to exclude section 30(1B) TMA because, self-evidently, it has no application to RAS claims.    

[131]  In summary, what Reg.14 does is to provide a mechanism for assessing, the time limits for doing so and the dates from which interest on those assessments run. It is neither futile nor absurd.

[132] Therefore I find that the appellant’s primary position that a return under section 8 or 8A should be read as a claim being made for RAS cannot be a remedy for any shortcomings in the interaction between the legislative provisions." (Killik & Co LLP v. HMRC [2023] UKFTT 653 (TC), Judge Anne Scott)

- Exception only applies to self assessment return (not certain pensions issues)

Further conditions to be satisfied if taxpayer submitted return

Income tax and CGT

"(3)     Where the taxpayer has made and delivered a return under section 8 or 8A of this Act in respect of the relevant year of assessment, he shall not be assessed under subsection (1) above—

(a)     in respect of the year of assessment mentioned in that subsection; and

(b)     in the same capacity as that in which he made and delivered the return,

unless one of the two conditions mentioned below is fulfilled.

 

(4)     The first condition is that the situation mentioned in subsection (1) above was brought about carelessly or deliberately by the taxpayer or a person acting on his behalf.

 

(5)     The second condition is that at the time when an officer of the Board—

(a)     ceased to be entitled to give notice of his intention to enquire into the taxpayer's return under section 8 or 8A of this Act in respect of the relevant year of assessment; or

(b)     in a case where a notice of enquiry into the return was given—

(i)     issued a partial closure notice as regards a matter to which the situation mentioned in subsection (1) above relates, or

(ii)     if no such partial closure notice was issued, issued a final closure notice,

the officer could not have been reasonably expected, on the basis of the information made available to him before that time, to be aware of the situation mentioned in subsection (1) above." (TMA 1970, s.29(3) - (5))

Corporation tax

"(1)     The power to make—

(a)     a discovery assessment for an accounting period for which the company has delivered a company tax return, or

(b)     a discovery determination,

is only exercisable in the circumstances specified in paragraph 43 [careless or deliberate] or 44 [not apparent from return] and subject to paragraph 45 [prevailing practice] below." (FA 1998, Sch 18, para 42(1))

SDLT

"(1)     If the purchaser has delivered a land transaction return in respect of the transaction in question, an assessment under paragraph 28 or 29 in respect of the transaction—

(a)     may only be made in the two cases specified in sub-paragraph (2) and (3) below, and

(b)     may not be made in the circumstances specified in sub-paragraph (5) below.

(2)     The first case is where the situation mentioned in paragraph 28(1) or 29(1) is attributable to fraudulent or negligent conduct on the part of—

(a)     the purchaser,

(b)     a person acting on behalf of the purchaser, or

(c)     a person who was a partner of the purchaser at the relevant time.

(3)     The second case is where the Inland Revenue, at the time they—

(a)     ceased to be entitled to give a notice of enquiry into the return, or

(b)     completed their enquiries into the return,

could not have been reasonably expected, on the basis of the information made available to them before that time, to be aware of the situation mentioned in paragraph 28(1) or 29(1)." (FA 2003, Sch 10, para 30)

Relevant year of assessment

"(9)     Any reference in this section to the relevant year of assessment is a reference to—

(a)     in the case of the situation mentioned in paragraph (a) or (b) of subsection (1) above, the year of assessment mentioned in that subsection; and

(b)     in the case of the situation mentioned in paragraph (c) of that subsection, the year of assessment in respect of which the claim was made." (TMA 1970, s.29(9))

Conditions do not apply to counteraction of double taxation relief avoidance arrangements

"(7A)     The requirement to fulfil one of the two conditions mentioned above does not apply so far as regards any income or chargeable gains of the taxpayer in relation to which the taxpayer has been given, after any enquiries have been completed into the taxpayer's return, a notice under section 81(2) of TIOPA 2010 (notice to counteract scheme or arrangement designed to increase double taxation relief)." (TMA 1970, s.29(7A))

No statutory obligation to consider conditions before assessing

“HMRC cannot have an obligation to investigate whether the taxpayer has been guilty of negligence or fraud before issuing the assessment, especially where s 29 does not, on its face, impose such an obligation.” (Hankinson v. HMRC [2011] EWCA Civ 1566, §24).

 

“If neither [condition] is fulfilled, the assessment should not have been made and will be invalid. And that is so whether the officer had formed the view that the conditions were fulfilled (and turns out to be wrong) or whether he has not considered them at all.” (Hankinson v. HMRC [2011] EWCA Civ 1566, §27 quoting Upper Tribunal with approval).

 

“…it is not necessary before HMRC can invoke the power in s. 29 for an officer to consider whether either or both of the conditions in s. 29(4) and s. 29(5) have been fulfilled. Unlike s. 29(2), s. 29(4) and s. 29(5) are not concerned with the officer's subjective views, but with the objective facts: has there been fraud, or negligence, or was the information objectively insufficient…” (Hargreaves v. HMRC [2014] UKUT 395 (TCC), §21(6)).
 

Objection that conditions not met must be made in statutory appeal

"(8)     An objection to the making of an assessment under this section on the ground that neither of the two conditions mentioned above is fulfilled shall not be made otherwise than on an appeal against the assessment." (TMA 1970, s.29(8))

Exception for assessment arising out of a claim for overpaid tax under schedule 1AB

"(1)     This paragraph applies where—

(a)     a claim is made under this Schedule,

(b)     the grounds for giving effect to the claim also provide grounds for a discovery assessment or determination on the claimant in respect of any chargeable period, and

(c)     such an assessment or determination could be made but for a relevant restriction.

(2)     “Discovery assessment or determination” means—

(a)     an assessment under section 29(1), or

(b)     a discovery assessment or discovery determination under Schedule 18 to the Finance Act 1998 (company tax return etc).

(3)     The following are relevant restrictions—

(a)     the conditions in section 29(3) to (5),

(b)     the restrictions in paragraphs 42 to 45 of Schedule 18 to the Finance Act 1998, and

(c)     the expiry of a time limit for making a discovery assessment or determination.

(4)     Where this paragraph applies—

(a)     the relevant restrictions are to be disregarded, and

(b)     the discovery assessment or determination is not out of time if it is made before the final determination of the claim." (TMA 1970, Sch 1AB, para 6)

For corporation tax see FA 1998, Sch 18, para 51E and 51F to the same effect.

Exception for discovery determination to give effect to assessment/determination on another company

"(2)     Those restrictions do not apply to an assessment or determination which only gives effect to a discovery determination duly made with respect to an amount stated in another company's company tax return."  (FA 1998, Sch 18, para 42(2))

Exception for capital loss avoidance and double tax relief avoidance

"(2A)     Those restrictions, other than the restriction in paragraph 45 [prevailing practice], do not apply so far as regards any income or chargeable gains of the company in relation to which the company has been given, a notice within sub-paragraph (4) after any enquiries have been completed into the return (so far as relating to the matters to which the notice relates).

(4)     A notice is within this sub-paragraph if it is—

(a)     a notice under section 184G or 184H of the Taxation of Chargeable Gains Act 1992 (avoidance involving capital losses), or

(b)     a notice under section 81(2) of TIOPA 2010 (schemes and arrangements designed to increase relief)."  (FA 1998, Sch 18, para 42(2A) and (4))

Further conditions to be satisfied if taxpayer submitted return

Condition 1: Loss of tax etc brought about carelessly or deliberately

 

Income tax and CGT

"(4)     The first condition is that the situation mentioned in subsection (1) above was brought about carelessly or deliberately by the taxpayer or a person acting on his behalf." (TMA 1970, s.29(4))

Corporation tax

"A discovery assessment for an accounting period for which the company has delivered a company tax return, or a discovery determination, may be made if the situation mentioned in paragraph 41(1) or (2) was brought about carelessly or deliberately by—

(a)     the company, or

(b)     a person acting on behalf of the company, or

(c)     a person who was a partner of the company at the relevant time." (FA 1998, Sch 18, para 43)

SDLT

"(2)     The first case is where the situation mentioned in paragraph 28(1) or 29(1) is attributable to fraudulent or negligent conduct on the part of—

(a)     the purchaser,

(b)     a person acting on behalf of the purchaser, or

(c)     a person who was a partner of the purchaser at the relevant time." (FA 2003, Sch 10, para 30)

Relevant behaviour must bring about the insufficiency in the assessment etc.

"[80]...The FTT concluded that Mr Hargreaves was in breach of duty in failing to take further advice from PwC prior to submitting the Return with the claim to be non-resident. The question which then arises is what would have happened if Mr Hargreaves had complied with his duty, and had sought and obtained the required further advice from PwC. That in turn raises the question of what advice PwC would have given in this hypothetical situation. By way of example, if PwC could legitimately (ie. non-negligently) have advised Mr Hargreaves that, despite the change in circumstances, it would still be appropriate for him to submit the Return with a claim to be non-resident, that would support Mr Hargreaves’ argument that the Situation was not attributable to the negligence found against him by the FTT..." (Hargreaves v. HMRC [2022] UKUT 34 (TCC, Edwin Johnson J and Judge Jonathan Richards)

"[119] The insufficiency in the assessment must be “brought about”, that is, caused by 25 the relevant carelessness. If the assessment to tax (as contained in the self-assessment tax return) states the wrong figure as to the tax payable and the wrong figure is stated as a result of carelessness, then the insufficiency in the assessment to tax is brought about by that carelessness. The question as to whether something is “brought about” and whether that happened as a result of carelessness is also dealt with in section 30 118(5) which provides that a relevant situation is brought about carelessly by a person if the person “fails to take reasonable care to avoid bringing about” that situation. This subsection makes the perhaps obvious point that a failure to take care to avoid a situation amounts to carelessly bringing about that situation. In other words, carelessness can take the form of omissions as well as positive acts." (HMRC v. Hicks [2020] UKUT 12 (TCC), Morgan J and Judge Brannan)

Onus on HMRC 

 

“The onus is on HMRC to establish negligence.” (Hargreaves v. HMRC [2014] UKUT 395 (TCC), §21(4)).
 

The assessment is only valid to the extent that the loss of tax is attributable to careless or deliberate behaviour

“There is no general power to raise assessments under s 29 and, in the case of s 29(4), the power that exists is limited to making good a loss of tax that is brought about by careless behaviour.” (Bubb v. HMRC [2016] UKFTT 216 (TC), §45).
 

See further G4: Time Limits

Condition 1: Loss of tax etc brought about carelessly or deliberately

Condition 2: Information in return not sufficient to make officer aware of loss of tax

 

Income tax and CGT

(5)     The second condition is that at the time when an officer of the Board—

(a)     ceased to be entitled to give notice of his intention to enquire into the taxpayer's return under section 8 or 8A of this Act in respect of the relevant [year of assessment; or

(b)     in a case where a notice of enquiry into the return was given—

(i)     issued a partial closure notice as regards a matter to which the situation mentioned in subsection (1) above relates, or

(ii)     if no such partial closure notice was issued, issued a final closure notice,

the officer could not have been reasonably expected, on the basis of the information made available to him before that time, to be aware of the situation mentioned in subsection (1) above." (TMA 1970, s.29(5))

Corporation tax

"(1)     A discovery assessment for an accounting period for which the company has delivered a company tax return, or a discovery determination, may be made if at the time when an officer of Revenue and Customs—

(a)     ceased to be entitled to give a notice of enquiry into the return, or

(b)     in a case where a notice of enquiry into the return was given—

(i)     issued a partial closure notice as regards a matter to which the situation mentioned in paragraph 41(1) or (2) relates, or

(ii)     if no such partial closure notice was issued, issued a final closure notice,

they could not have been reasonably expected, on the basis of the information made available to them before that time, to be aware of the situation mentioned in paragraph 41(1) or (2)." (FA 1998, Sch 18, para 44(1))

SDLT

"(3)     The second case is where the Inland Revenue, at the time they—

(a)     ceased to be entitled to give a notice of enquiry into the return, or

(b)     completed their enquiries into the return,

could not have been reasonably expected, on the basis of the information made available to them before that time, to be aware of the situation mentioned in paragraph 28(1) or 29(1)." (FA 2003, Sch 10, para 30)

Time when officer ceased to be able to enquire: amendment only extends the enquiry window in relation to matters in the return to which the amendment relates or affects

 

“The effect of the amendment and S 9A(2)(c) TMA was to extend the enquiry window to 31 October 2009 but only in relation to anything in the return ‘to which the amendment relates or which are affected by the amendment’.” (Miesagaes v. HMRC [2016] UKFTT 375 (TC), §21).

Purpose of rule


“It seems to me that its purpose is to simplify and bring about early finality of assessment to tax, based on an assumption of an honest and accurate return and accompanying documentation by the taxpayer.” (Langham v. Veltema [2004] EWCA Civ 193, §31 - query how the return can be accurate if an assessment is otherwise justified).

Negative formulation (office could 'not' be expected to be aware) not relevant

"[43] Mr Goldberg also argued that the authorities to date have ignored a crucial aspect of s29(5). Section 29(5) is expressed in the negative asking whether the hypothetical officer could not have been reasonably expected to have a particular level of awareness. That, he argued is a very different question from asking whether the hypothetical officer could reasonably have been expected to have the requisite awareness. Moreover, he argued that the difference was deliberate: Parliament consciously wished to make it “hard” for HMRC to make discovery assessments since the self-assessment regime envisaged that HMRC should be opening enquiries under s9A of TMA in cases where they had concerns about a taxpayer’s self-assessment. Accordingly, Mr Goldberg’s submission was that Parliament had deliberately provided for s29(5) to permit the making of a discovery assessment only where the hypothetical officer could not have had any reasonable doubts as to the correctness of a taxpayer’s self-assessment on the basis of the information specified in s29(6).

[44] We reject that argument. Auld LJ considered and rejected a variant of it in paragraph [35] of his judgment in Langham v Veltema as follows:

"35. Accordingly, I do not agree with Mr. Sherry that the Commissioners, in considering whether the Inspector could not have been reasonably expected to be aware of the insufficiency, were entitled to take into account what enquiries he could reasonably have been expected to undertake from the information provided to him under section 29(6) and what he could have reasonably learned from them. The fact that the statutory test is framed in the negative, that the Inspector could not have been reasonably expected to have been aware of the insufficiency, does not, in my view, affect the subject matter of the objective awareness with which the provision is concerned, actual insufficiency."" (Hargreaves v. HMRC [2022] UKUT 34 (TCC, Edwin Johnson J and Judge Jonathan Richards)

Condition 2: Information in return not sufficient to make officer aware of loss of tax

- Aware of an insufficiency/undercharge

Awareness relates to insufficiency not discovery of insufficiency 

 

“Both s. 29(4) and s. 29(5) use the same language as s. 29(3) in referring to “the situation mentioned in subsection (1) above”. [HMRC] submitted that this referred to the fact of the undercharge, and had nothing to do with the officer's discovery of the fact. I accept this submission which seems to me plainly to be right as a matter of language.” (Hargreaves v. HMRC [2014] UKUT 395 (TCC), §21(6)).

 

Burden of proof on HMRC (but not likely to be relevant) 

 

"[203] With respect, we think it would have been preferable if the FTT had simply considered the evidence in relation to the information made available to the hypothetical officer which it summarised at [93]-[101] and, applying the objective test in section 29(5), reached its conclusion without reference to the burden of proof."  (HMRC v. Hicks [2020] UKUT 12 (TCC), Morgan J and Judge Brannan)

“…it seems to me that the burden of establishing that [43] or [44] apply must rest on HMRC, because in the absence of any evidence of fraud or negligent conduct ([43]), or of material to satisfy the test of objective non-awareness ([44]), there would be no basis for a conclusion that either of those paragraphs applied, and nothing to displace the general rule that discovery assessments may not be made. I would add, however, that in relation to [44] the question is unlikely to be of much practical significance, because the nature of the enquiry is an objective one and the return and accompanying documents which have been submitted to HMRC should always be available.” (HMRC v. Household Estate Agents Ltd [2007] EWHC 1684 (Ch), §48).

 

“…although the onus under s. 29(5) is on HMRC as it is under s. 29(4), in practice the question is unlikely to be of much practical significance, because the return and accompanying documents in fact submitted to HMRC should always be available and the nature of the enquiry is an objective one.” (Hargreaves v. HMRC [2014] UKUT 395 (TCC), §21(8) – see also §24(1) “common ground”).

 

“…the burden of proof of establishing that the condition contained in section 29(5) is satisfied lies on HMRC.” (Blumenthal v. HMRC [2012] UKFTT 497 (TC), §166).

 

Awareness is an objective question 

 

“The subjective opinions of the assessing officer or the Board about fulfilment of the conditions have no part to play in the operation of s 29.” (Hankinson v. HMRC [2011] EWCA Civ 1566, §§27 - 28).

 

“The test is both an objective and a negative one.” (HMRC v. Household Estate Agents Ltd [2007] EWHC 1684 (Ch), §29).

 

“Unlike s. 29(2), s. 29(4) and s. 29(5) are not concerned with the officer's subjective views, but with the objective facts: has there been fraud, or negligence, or was the information objectively insufficient“(Hargreaves v. HMRC [2014] UKUT 395 (TCC), §21(6)).

 

But perhaps not completely objective 

 

"[169] Although the FTT incorrectly considered that it was reasonable “to assume that the hypothetical officer will be likely to be in a similar position [to that of the actual officer] by [the summer of 2014]”, the FTT noted the acknowledgement of the Court of Appeal in Sanderson at [25] that “…there would inevitably be points of contact between the real and hypothetical exercises which sub-ss 29(1) and (5) involve [although] the tests are not the same.”(HMRC v. Hicks [2020] UKUT 12 (TCC), Morgan J and Judge Brannan)

"To the untutored mind, that reference to “the officer” would appear to be a reference back to the officer (“an officer”) mentioned at the beginning of subsection (5) who, at the cut-off date, ceased to be entitled to give notice of his intention to enquire into the taxpayer’s return. In other words, it is a particular individual, not an abstract hypothetical officer with the knowledge and expertise mentioned in Charlton nor an average or reasonable officer riding the fiscal equivalent of the Clapham omnibus.” (Pattullo v. HMRC [2016] UKUT 270 (TCC), §79, Lord Glennie, did not base his decision on this view, however)

 

“The hypothetical officer is not a hypothetical officer in a vacuum but rather one who is standing in the shoes of the actual officer or in this case, a reasonable officer at Salford.” (Freeman v. HMRC [2013] UKFTT 496 (TC), §52).

 

Relevance of burden of proof terminology 

 

“Awareness is a matter of perception and of understanding, not of conclusion. I wish, therefore, to express doubt as to the approach of the Special Commissioner in Corbally-Stourton v Revenue and Customs Comrs [2008] STC (SCD) 907 and of the Outer House in R(on the application of Patullo) v Revenue and Customs Commissioners [2010] STC 107, namely, that to be aware of a situation is the same as concluding that it is more probable than not.” (HMRC v. Lansdowne Partners Ltd Partnership [2011] EWCA Civ 1578, §70).

 

“The Upper Tribunal noted that the test was one of awareness, a matter of perception and understanding, and not one of certainty or probability (paragraph 92); and not one of conclusion. However, a state of awareness, understanding or perception seems to be the result of the application of the test rather than the test itself (cf paragraph 58). Moreover, it is difficult to see why a conclusion is excluded from a state of awareness. One plus one equals two. Two is the result of adding one to one. It is a conclusion. Knowing that one plus one makes two is a state of awareness. We agree, however, that the awareness of a hypothetical officer is not to be measured by probabilities. Probability is normally deployed to determine facts. The deemed awareness of the hypothetical officer is determined by reference to the s 29(6) information available, the attributes he is deemed to have, and the thought processes with which he is imbued.” (Pattullo v. HMRC [2014] UKFTT 841 (TC) §71).

 

“In our view, although Mr Stewart had indicated as early as October 2007 the probability that he would be making assessments under the relevant statutory provisions, this did not amount to a conclusion that it was probable that there was an insufficiency; it was not until November 2009 that he had the information enabling him to make a reasonable calculation of the amount of the insufficiency.” (Thomas v. HMRC [2016] UKFTT 133 (TC), §96).

 

Aware of actual insufficiency rather than possibility/need for further enquiries 

 

“…it is plain from the wording of the statutory test in s 29(5) that it is concerned, not with what an Inspector could reasonably have been expected to do, but with what he could have been reasonably expected to be aware of. It speaks of an Inspector's objective awareness, from the information made available to him by the taxpayer, of “the situation” mentioned in s 29(1), namely an actual insufficiency in the assessment, not an objective awareness that he should do something to check whether there is such an insufficiency …” (Langham v. Veltema [2004] EWCA Civ 193, §33).

 

“Had he applied his mind to the question, his experience of other EBTs, and indeed common sense, might well have led him to doubt the correctness of the self-assessment and to open an enquiry; but that is a very different thing from saying that he should be regarded as knowing, or as having inferred, what such an enquiry would probably have revealed.” (HMRC v. Household Estate Agents Ltd [2007] EWHC 1684 (Ch), §40).

 

“ ‘Awareness’ refers to the officer's awareness of an insufficiency in the self-assessment return, rather than an awareness that he should do something to check whether there is an insufficiency. It is not enough that the officer should realise that he should make further enquiries;” (Blumenthal v. HMRC [2012] UKFTT 497 (TC), §167(1)).

 

Constructive awareness/inference of insufficiency is sufficient

 

“Such provision for awareness of insufficiency "on the basis" of the specified information or from information that could reasonably be expected to be inferred therefrom does not, in my view, denote an objective awareness of something less than insufficiency. It is a mark of the way in which the subsection provides an objective test of awareness of insufficiency, expressed as a negative condition in the form that an officer "could not have been reasonably expected … to be aware of the" insufficiency. It also allows, as section 29(6) expressly does, for constructive awareness of insufficiency, that is, for something less than an awareness of an insufficiency, in the form of an inference of insufficiency.” (Langham v. Veltema [2004] EWCA Civ 193, §34).

 

“Section 29(5) allows for constructive awareness of insufficiency, that is, for something less than an awareness of insufficiency, in the form of an inference of insufficiency…” (Blumenthal v. HMRC [2012] UKFTT 497 (TC), §167(6)).

 

Unnecessary to be able to quantify the tax loss 

 

“It is not necessary for the officer to arrive at a precise calculation; the information available will frequently be insufficient to achieve anything other than an approximation. However, it is necessary for the officer to be able to arrive at the view that income or gains are attributable to the particular year so that the loss of tax can be sufficiently identified for the purposes of s 29(1) TMA 1970. There is a difference between knowing that a person is potentially assessable and having a sufficient basis to enable the HMRC officer to arrive at a reasonable estimate of the alleged loss of tax for the year in question.” (Thomas v. HMRC [2016] UKFTT 133 (TC), §93).

 

“…the test in s 29(5) is not that the officer should be able to quantify the potential tax loss, only that he/she could be reasonably expected to be aware of the potential tax loss.” (Ive v. HMRC [2014] UKFTT 400 (TC), §35(2)).

 

No account taken of what enquiries the officer could reasonably be expected to undertake 

 

“…account should not be taken of what enquiries the Inspector could reasonably have been expected to undertake from the information supplied to him under s 29(6) and of what he could have reasonably learned from such enquiries” (HMRC v. Household Estate Agents Ltd [2007] EWHC 1684 (Ch), §32(b)).

 

Sufficient that the information justified the assessment 

 

“I do not suggest that the hypothetical inspector is required to resolve points of law. Nor need he forecast and discount what the response of the taxpayer may be. It is enough that the information made available to him justifies the amendment to the tax return he then seeks to make. Any disputes of fact or law can then be resolved by the usual processes.” (HMRC v. Lansdowne Partners Ltd Partnership [2011] EWCA Civ 1578, §56 – the lack of indication that rebates of management fees to partners had been treated differently to those paid to non-partners did not stop the officer having awareness).

 

“It is scarcely surprising that HMRC’s confidence that the Scheme did not work increased over time. However, in this case that was largely attributable not to additional material information, but to the detailed research and efforts of HMRC which were co-ordinated by Officer Boote… On the facts in this case, the hypothetical officer had sufficient information available (taking into account section 29(6)) at closure of the enquiry window to make it reasonable for him to have been justified in raising an assessment for the insufficiency. The central issues, relating to section 730 and trading, were not matters of such complexity that the disclosure did not achieve this result.” (Hicks v. HMRC [2018] UKFTT 22 (TC), §§119…121, Judge Thomas Scott).


“In our view, section 29(5) requires that a taxpayer should make sufficient disclosure in order to enable an officer to make an informed decision whether an insufficiency existed sufficient to justify, in the words of Moses LJ, the exercise of the power to raise a discovery assessment under section 29(1).” (Blumenthal v. HMRC [2012] UKFTT 497 (TC), §173).

 

Or not:

 

“HMRC may have sufficient disclosure to raise a discovery assessment because of a ‘possible insufficiency’ (see [25] of Sanderson) under s 29(1) but that disclosure may be insufficient to protect a taxpayer from such an assessment because the disclosure did not create awareness of an actual insufficiency.” (Miesegaes v. HMRC [2016] UKFTT 375 (TC), §97 relying on Sanderson, CA).

 

Level of legal understanding 

 

“Whether it is put as a characteristic of the ordinarily competent HMRC officer, or as part of the knowledge and understanding which the Charltonesque hypothetical officer would bring to bear on an examination of the tax return, I agree with the observations of the FTT at paras 74 and 77. I would not expect the hypothetical officer as early as 31 January 2006 to have any real understanding of the arcane world of CRCs. Some might have been aware of SHIPS – SI had begun investigations into SHIPS in 2004 – but investigation into CRCs was lagging behind the investigation into SHIPS.” (Pattullo v. HMRC [2016] UKUT 270 (TCC), §82, Lord Glennie).

 

“The officer must be assumed to have such a level of knowledge and understanding that would reasonably be expected in an officer considering the particular information provided by the taxpayer.” (HMRC v. Charlton [2012] UKUT 770 (TCC), §58).

 

“So the hypothetical officer is in general taken to understand the law as it relates to the facts disclosed by the taxpayer…It is also clear that the hypothetical officer is not deemed to consult with more specialist colleagues even if, in the real world, it might be supposed that that is what an HMRC officer considering the taxpayer’s return would do:  Charlton  at [53].” (Miesegaes v. HMRC [2016] UKFTT 375 (TC), §§82…88)

 

“In argument before us [HMRC] came close to suggesting, as we understood it, that a hypothetical officer could not be expected to understand complex or specialist areas of tax law. We disagree. If the disclosure (factual and technical) is adequate in the circumstances of the case, a hypothetical officer can reasonably be expected to be aware of an insufficiency even in a complex case or one involving specialist technical knowledge. If the disclosure is inadequate then it is fair that a hypothetical officer could not reasonably be expected to be aware of insufficiency in such a case. That is the balance that section 29(5) strikes.” (Blumenthal v. HMRC [2012] UKFTT 497 (TC), §179).

 

“However, an HMRC officer, in order, ever, to become aware of an insufficiency of tax must have some general knowledge of tax law and practice. We do not consider that it is reasonable to expect him to be aware of the arcane world of capital redemption contracts or that they are specifically mentioned in the HMRC Manual.“ (Pattullo v. HMRC [2014] UKFTT 841 (TC) §74, upheld on appeal – see above).

 

Unlikely possibilities arising from facts which would not lead to insufficiency of tax block awareness 

 

“…however unlikely it may have been as a matter of practical common sense, it was a course of action legitimately open to the trustees, and there were therefore circumstances in which the Company could properly have deducted the £60,000 in computing its Sch D profits. Since the Company computed its profits on the basis that the £60,000 was deductible, and since no relevant adjustment was made to reverse that deduction in the tax computation submitted to the Inspector, he was entitled to proceed on the basis that the Company's self-assessment was correct.” (HMRC v. Household Estate Agents Ltd [2007] EWHC 1684 (Ch), §39).

 

Substantive taxing provisions not to be interpreted as requiring officer to make any factual presumptions 

 

“[The taxpayer] submitted that the structure of s 43 of the Finance Act 1989 is such that the Inspector was required to proceed on the footing that the £60,000 was not deductible unless the Company provided evidence of the payment of actual emoluments within the requisite period. I do not agree. As I have already pointed out, it was possible (if unlikely) that the trustees had in fact used the £60,000 to pay actual emoluments before the date when the Company's return for 1999 was submitted, and in submitting the return as it did the Company was in effect representing that this was indeed what had occurred. The Inspector was in my view clearly entitled to accept this representation at face value, in the absence of anything in the documents supplied with the return to show that it was wrong.” (HMRC v. Household Estate Agents Ltd [2007] EWHC 1684 (Ch), §42).

 

Too much information may block awareness unless relevance explained 

“The information contained in the additional material may have been fully covered within the return or, alternatively, there may be so much material that the Inland Revenue officer 'could not have been reasonably expected, on the basis of the information made available to him before that time, to be aware'(new Section 29(5) TMA 1970,) of the particular point of liability, unless the taxpayer or agent had explained its relevance. Where voluminous information beyond the accounts and computations is sent with the return, therefore, it is recommended that there should be a brief indication of the relevance of the material.” (Tax Bulletin 23 (1996)).
 
“Information will not be treated as being made available where the total amount supplied is so extensive that an officer "could not have been reasonably expected to be aware" of the significance of particular information and the officer's attention has not been drawn to it by the taxpayer or taxpayers representative.” (Statement of Practice 1/06).

 

“In our view, the Statement of Practice is not inconsistent with the case law. We agree that, in context, the Statement of Practice insists on sufficient disclosure necessary to disclose an insufficiency but is also warning taxpayers not to "bury" relevant information in a mass of disclosures. This seems to us a perfectly reasonable point to make and we agree that the officer is not required to find a needle in a factual haystack.” (Blumenthal v. HMRC [2012] UKFTT 497 (TC), §190).

 

Complex legal issues may block awareness 

 

“I wish to leave open the possibility that, even where the taxpayer has disclosed enough factual information, there may be circumstances in which an officer could not reasonably be expected to be aware of an insufficiency by reason of the complexity of the relevant law.” (HMRC v. Lansdowne Partners Ltd Partnership [2011] EWCA Civ 1578, §69).

 

"[197] In a relatively simple case, where the legal principles are clear, it would be sufficient for a taxpayer simply to give a full disclosure of the factual position. The return must also make clear what position the taxpayer is adopting in relation to the factual position (e.g. whether a receipt was not taxable or whether a claim for relief was being made).

[198] But there may be other cases where the law and the facts (and/or the relationship between the law and the facts) are so complex that adequate disclosure may require more than pure factual disclosure: namely some adequate explanation of the main tax law issues raised by the facts and the position taken in respect of those issues.

[199] Plainly, the greater the level of disclosure, the greater the officer's awareness can reasonably be expected to be. If a disclosure on a tax return includes all material facts and, in complex cases, an adequate explanation of the technical issues raised by those facts and the position taken in relation to those issues, it would be reasonable to expect an officer to be aware of an insufficiency. What constitutes reasonable awareness is linked to the fullness and adequacy of the disclosure – the expertise of the hypothetical officer remains that of general competence, knowledge or skill which includes a reasonable knowledge and understanding of the law." (HMRC v. Hicks [2020] UKUT 12 (TCC), Morgan J and Judge Brannan)

“We respectfully agree with Moses LJ that the possibility should remain open that mere factual disclosure may not, in some cases involving complex issues of law, be sufficient…But there may be other cases where the law and the facts (and/or the relationship between the law and the facts) are so complex that adequate disclosure may require more than pure factual disclosure: namely some brief explanation of the main tax law issues and the position taken in respect of those issues. An officer is not required to play "spot the [fiscal] ball" in complex cases.” (Blumenthal v. HMRC [2012] UKFTT 497 (TC), §§173…177).

 

Uncertain area of law may block awareness unless taxpayer discloses its view of the law

 

“But what if the law is unclear rather than complex?  The Chancellor in Lansdowne  at [56] (cited also in Charlton at [52] and Sanderson  at [23])  said that an HMRC officer is not required to resolve points of law.  What does this mean for a taxpayer who has completed his tax return fully disclosing all relevant facts but on a particular view of the law which others might interpret somewhat differently?  Does that mean the hypothetical officer is not fixed with an awareness of the insufficiency (should the taxpayer’s view prove to be wrong) because the hypothetical officer is not required to resolve an uncertain question of law?  We think that the answer may be that where interpretation of the law is uncertain, the taxpayer needs to disclose not only the law on which he relies but his view of the law.” (Miesegaes v. HMRC [2016] UKFTT 375 (TC), §84).

 

Not required to state that the return is doubtful 

 

“We should also add, at this point, that section 29(5) does not require a taxpayer to state or imply that his or her return is or may be doubtful or incorrect.” (Blumenthal v. HMRC [2012] UKFTT 497 (TC), §185).

 

But a contrary view can be found:

 

“The full factual position would have included a statement that the petitioner was part of such a scheme and a full statement of the legal position would have included a statement of doubt or a statement that a contrary position to the HMRC was being insisted upon together with a clearer picture of the operation of the scheme.” (Re Pattullo [2009] CSOH 137, §115).
 

- Aware of an insufficiency/undercharge

- Hypothetical awareness of income tax insufficiency not enough if there is also a CGT insufficiency 

 

"[55] HMRC take the diametrically opposite view. They reason that s29(1) permits HMRC to make a discovery assessment if they “discover” that, among other matters, any income or capital gains have not been assessed. Therefore, when s29(5) asks about the awareness of a hypothetical officer of the “situation mentioned in subsection (1)”, that is a reference back to “any” income tax or CGT not being assessed. Since the hypothetical officer could not have been aware that there was any insufficiency as regards Mr Hargreaves’ self-assessment to CGT (because Mr Hargreaves had not completed the capital gains pages of the Return), HMRC argue that they would not be precluded from making a discovery assessment as regards both income tax and CGT even if (which they do not accept) any insufficiency of income tax was readily apparent from the face of the Return.

[56] We do not regard this point as straightforward and, for reasons that we have given, it is not necessary to our conclusion. We consider that some support for HMRC’s approach can be found in paragraphs [46] and [47] of the judgment of Arden LJ (as she then was) in Hargreaves v HMRC [2016] EWCA Civ 174 where she said:

Draconian effect of tiny error?

46. Mr Goldberg submits that the power to make a [discovery assessment] is penal in its effect. He submits that, if the taxpayer makes a small mistake, the door is open to HMRC to reopen the computation of all tax for the relevant period. This is because "the situation mentioned in subsection (1) above" (used in subsections (2) and (5)) is that "any income which ought to have been assessed to income tax" has not been assessed. Thus, if the taxpayer had treated income of £100 as not liable to tax, and HMRC assesses the full £100 to tax but HMRC can show that the conduct condition is met only in respect of £50, then on a literal reading of section 29 it would appear to follow that the whole of the assessment meets the conduct/officer condition and is validly made. This is a startling conclusion.

47. I do not consider that this difficulty exists. I accept the submission of Mr Nawbatt that, once HMRC have shown that the conduct/officer condition is met, the taxpayer can show that the amount assessed is excessive. The position under section 29 is analogous to that where an assessment is made under section 36 TMA on the grounds of the taxpayer's fraudulent or negligent conduct…

[57] In this passage, Arden LJ does not expressly accept the premise of Mr Goldberg’s argument set out at [46] of the extract. She states only that its effect was not “draconian” because if HMRC made the assessment of £100 the taxpayer would be entitled to appeal to the FTT and seek to establish that the assessment was excessive. However, it might be expected that, if she disagreed with the premise of Mr Goldberg’s submission, she would have said so. Accordingly, we prefer HMRC’s submission set out in paragraph [55] above to Mr Hargreaves’ competing submission set out in paragraph [54].

These subsections are exhaustive 

 

“It seems to me that the key to the scheme is that the Inspector is to be shut out from making a discovery assessment under the section only when the taxpayer or his representatives, in making an honest and accurate return or in responding to a section 9A enquiry, have clearly alerted him to the insufficiency of the assessment, not where the Inspector may have some other information, not normally part of his checks, that may put the sufficiency of the assessment in question.” (Langham v. Veltema [2004] EWCA Civ 193, §36).

 

“The sources of information referred to in section 29(6) [as amplified by section 29(7)] are the only sources of information to be taken into account in deciding whether an officer ought reasonably to have been aware of the actual insufficiency.” (Blumenthal v. HMRC [2012] UKFTT 497 (TC), §167(5)).

 

"In Veltema and Household Estate Agents, it is made clear that the only information which should be treated as being available to the inspector for the purposes of Section 29(5) was that listed in Section 29(6). But the tail piece of Section 29(6) speaks of what it would have been reasonable to expect the officer objectively to have been aware of on the basis of that information. In determining what it is reasonable to expect of an officer some knowledge must be attributed to him: he must have some awareness of the rules of elementary arithmetic, some knowledge of tax law, and some general knowledge. All of those he must be treated as applying and determining what it is reasonable to expect of him.” (Corbally-Stourton v. HMRC [2008] UKSPC 00692, §56; approved in Re Pattullo [2009] CSOH 137, §105).

 

Composition of the tax return (s.29(6)(a))

 

“‘return’ includes any statement or declaration under the Taxes Acts” (TMA 1970, s.118(1)).

 

“I have already concluded that the information contained in the letter dated 30 August 2006 and its accompanying documents are to be seen as part of the return.” (Spring Salmon & Seafood Ltd v. HMRC [2014] UKUT 488 (TCC), §43 – a letter was sent enclosing short form tax returns, financial statements and a corporation tax computation).

 

Previous returns and partnership returns

 

See s.29(7)(a), set out above.


Not a trust return

 

“…as a matter of purposive interpretation, if Parliament had intended the contents of a relevant trust return to be deemed to be known to the HMRC officer considering the taxpayer’s tax return, then it could have said so.  Parliament did say so in respect of (a) the taxpayer’s previous two tax returns and (b) the partnership return of any partnership to which the taxpayer belonged.” (Miesegaes v. HMRC [2016] UKFTT 375 (TC), §51).

 

Information whose relevance is inferred

 

Information rather than a document

 

“We do not think a tax return can be regarded as ‘information’:  it is the contents of a tax return which amounts to information.  This is borne out by the structure of s 29 which refers to information ‘contained’ in a return.” (Miesegaes v. HMRC [2016] UKFTT 375 (TC), §29).

 

Infer existence and relevance

 

“In this case, however, even if the existence of the trust tax return ought to have been inferred, there was nothing in the appellant’s tax return which suggested that the trust tax return would have an explanation of the entries on the taxpayer’s return.  The weakness in the appellant’s case is that even if it was a reasonable inference that the Settlement would have submitted a tax return, there was nothing in the appellant’s tax return from which the hypothetical officer should reasonably have inferred the existence of the white space disclosure made in the trust tax return...It would have been mere speculation on the part of the hypothetical officer, and not an inference, that the white space disclosure existed and was relevance” (Miesegaes v. HMRC [2016] UKFTT 375 (TC), §§44…48).

 

Taxpayer notifies relevance (d(ii))

 

“…it is open to the taxpayer or agent to write to the Inland Revenue explaining the existence and relevance of any particular material for the purposes of making an adequate disclosure.” (Tax Bulletin 23 (1996)).

 

Information that may or may not exist not to be attributed until actually supplied 

 

“in circumstances such as this the valuation might not in fact support the figure in the taxpayer’s tax return. In that event, in my judgment on the true construction of section 29(6)(d)(i) the Inspector is not to have attributed to him the further information that he would actually have obtained if he had asked for that valuation, unless and until it is produced to him.” (Langham v. Veltema [2004] EWCA Civ 193, §51, Arden LJ whose approach was preferred by Henderson J in HMRC v. Household Estate Agents Ltd [2007] EWHC 1684 (Ch), §32(b)).

 

Conclusions based on information also available 

 

“…it is difficult to see why a conclusion is excluded from a state of awareness.” (Pattullo v. HMRC [2014] UKFTT 841 (TC) §71).

Quantum of assessment

Quantum of assessment

Assessment must be for the amount that “in the opinion” of the officer ought to be charged to make good the loss of tax

 

“However, in the course of writing up the Reasons accompanying the Directions released on 1 June 2016, we also decided that a prior question to be answered was whether all the assessments had been made in the amount(s) which, in the opinion of the officer making them, ought to be charged in order to make good to the Crown the loss of tax.” (Bell v. HMRC [2016] UKFTT 785 (TC), §79, Judge Walters QC)
 

- Assessment must be for the amount that “in the opinion” of the officer ought to be charged to make good the loss of tax

- Burden of proof on HMRC

 

“This is an issue which the burden of proof lies on HMRC.” (Bell v. HMRC [2016] UKFTT 785 (TC), §79, Judge Walters QC)

- Burden of proof on HMRC

- Generous degree of flexibility

 

“In the absence of some record in the mind or in the books of the taxpayer, it would often be quite impossible to make a correct assessment. The assessment would necessarily be a guess to some extent, and almost certainly inaccurate in fact. There is every reason to assume that the legislature did not intend to confer upon a potential taxpayer the valuable privilege of disqualifying himself in that capacity by the simple and relatively unskilled method of losing either his memory or his books…The application of the [relevant provision permitting a best of judgment assessment to be made] is not, in my opinion, excluded as soon as it is shown that an element in the assessment is a guess and that it is therefore very probably wrong. It is prima facie right - and remains right until the appellant shows that it is wrong. If it were necessary to decide the point I would, as at present advised, be prepared to hold that the taxpayer must, 'at least as a general rule', go further and show, not only negatively that the assessment is wrong, but also positively what correction should be made in order to make it right or more nearly right. I say 'as a general rule' because, conceivably, there might be a case where it appeared that the assessment had been made upon no intelligible basis even as an approximation, and the court would then set aside the assessment and remit it to the commissioner for further consideration.” (Trautwein v Federal Commissioner of Taxation (1936) 56 CLR 63 at 87 cited in Bi-Flex Caribbean Ltd v Board of Inland Revenue (1990) 63 TC 515)

- Generous degree of flexibility

- Intelligible basis of approximation required

 

“The question therefore arose whether all the assessments in this case have been made on an intelligible basis as an approximation - and it was for HMRC to show that they have. Mr Bell's case, of course, is that they have not.” (Bell v. HMRC [2016] UKFTT 785 (TC), §82, Judge Walters QC).

- Intelligible basis of approximation required

- Assessment discharged if not intelligible basis

 

“We concluded, following the third hearing, that were we to find that those assessments had not been made on an intelligible basis, even as an approximation, it would follow that they had not been properly made in the exercise of the power provided by section 29 TMA and that we should be bound to set them aside, and remit the matter to HMRC for further consideration - involving, presumably, the making of fresh assessments made on an intelligible basis.” (Bell v. HMRC [2016] UKFTT 785 (TC), §85, Judge Walters QC).

- Assessment discharged if not intelligible basis

No intelligible basis if no correlation between information HMRC relied on to increase profits and assessed increase

 

“Officer Turner was unable to show the Tribunal what evidence of 'actual deposits' supported the figures in the schedule referred to in the previous paragraph…Because of this, we have concluded that HMRC has failed to discharge the burden of proof on them of showing that the assessments… [have]been 'made on an intelligible basis, even as an approximation'.” (Bell v. HMRC [2016] UKFTT 785 (TC), §§102 - 103, Judge Walters QC).

- No intelligible basis if no correlation between information HMRC relied on to increase profits and assessed increase

- Unreasonably large assessments intended to frighten the taxpayer to cooperate are invalid

 

"In our judgement when the figure of 50% net profit margin was adopted by the respondents, that could not possibly have been a fair inference and/or a judgement which could properly be characterised as “best”. We are entirely satisfied that if any judgement whatsoever was brought to bear upon this issue, it certainly cannot be described as “best”. It smacks of being a situation where, because the appellant had been uncooperative and was sticking his head in the sand, the respondents decided to issue assessments almost “in terrorem”,in a bid to persuade the appellant to engage properly in the matters under review. The assessments would certainly meet that description if the appellant’s assertion that he is in receipt of DWP benefits and is somebody without any or any significant means, proves to be true. In our judgment the amounts charged by the assessments are so unreasonable that (a) no reasonable officer could hold that opinion when issuing the assessments, and/or (b) that same would properly make good the loss of any tax that was properly due. Rather the primary purpose was to frighten the taxpayer into responding to requests for information. It follows that the assessments were not authorised by s29 TMA." (Cussens v. HMRC [2019] UKFTT 543 (TC), §28, Judge Geraint Jones QC).

- Unreasonably large assessments intended to frighten the taxpayer to cooperate are invalid

Human rights

 

No discovery assessment to tax same profits twice (breach of human rights)

 

“Taking all of this into account, and recognising the high hurdles that Mr Fessal has to surmount, we think that, on balance, he has satisfied us that the provisions of section 29 TMA prior to any A1P1 override are not consistent with his rights under the A1P1 and that the aggregate amount of tax which is payable under the two assessments which are the subject of this appeal should be reduced to reflect that… Section 29 TMA could just as easily be construed on the basis that the A1P1 override is not a pre-condition to assessment but instead simply amends the quantum of the assessment that HMRC is empowered to make.  In other words, the A1P1 override means that the powers of the relevant representative of HMRC are to make an assessment in an amount which the relevant representative considers to be necessary to make good the loss of tax but only to the extent that the assessment does not lead to a breach of the taxpayer’s A1P1 rights by disregarding, in the assessment, any tax which has already been paid on the same profits, albeit in respect of a different tax year.  That would be the more natural way of construing section 29 TMA in the light of the injunction in section 3 HRA and we therefore adopt it.” (Fessal v. HMRC [2016] UKFTT 285 (TC), §§64…67)
 

Human rights

Certain PAYE-related assessments to be in accordance with generally prevailing practice

 

"(1)     This section applies if—

(a)     an assessment to income tax is made as respects relevant income (with or without other income), and

(b)     the assessment is made after the end of the period of 12 months following the tax year for which it is made.

(2)     In so far as it relates to relevant income, the assessment is to be made in accordance with the practice generally prevailing at the end of that period.

(3)     “Relevant income” means income which—

(a)     has been taken into account in the making of deductions or repayments of tax under PAYE regulations, and

(b)     was received not less than 12 months before the beginning of the tax year in which the assessment is made." (ITEPA 2003, s.709)

Certain PAYE-related assessments to be in accordance with generally prevailing practice

Alternative assessments

 

HMRC entitled to issue alternative assessments against the same taxpayer

 

“In those circumstances the inspector of taxes decided to put in alternative assessments. In one he was assessing on the basis that the gains were part of income, and on the other he was assessing on the basis that they were capital gains for the purposes of the Capital Gains Tax Act 1965. He was following a practice which, so far as income tax is concerned, has long been accepted as being a sensible and proper way of dealing with difficult cases.” (Bye v. Coren [1986] STC 393 at 394 per Lawton LJ).

 

“Nor do we see any good reason why the use of alternative assessments should be restricted to circumstances where the charging provisions are wholly distinct. As with direct taxes, alternative assessments for VAT provide in appropriate cases a practical and workable machinery for the ultimate recovery of the tax properly due.” (University Court of the University of Glasgow v. CEC, 20 February 2003, CSIH, §16, Lord Hamilton).

 

HMRC entitled to issue alternative assessments against different taxpayers

 

“In cross-examining Mr Kane, Mr Gordon sought to show that by keeping the determinations in force at the same time as making the discovery assessment, Mr Kane had not come to a settled view as to the liability of Operations to SDLT…I do not consider that the making of a discovery assessment in circumstances where the identity of the person or entity liable to tax remains uncertain, but where there is certainty in the view that one of the relevant parties is so liable, can be regarded as failing to meet the conditions in para 28(1) Sch 10. Nor in my view does it suggest that the officer is not acting honestly and reasonably. Transactions or schemes may work in alternative ways; see Howard Peter Schofield v Revenue and Customs Commissioners [2011] UKUT 306 (TCC) at [34]. It is entirely understandable for HMRC to seek to keep their respective options open; the outcome may remain uncertain until the matter is determined, as illustrated by the conclusions in this decision.” (Crest Nicholson (South East) Ltd v. HMRC [2017] UKFTT 136 (TC), §§255…257, Judge John Clark).

 

“Furthermore, in cases where the position is uncertain, it is entirely appropriate for HMRC to proceed on alternative bases.  The case law establishes quite clearly that HMRC is entitled to issue alternative assessments in order to prevent loss of tax properly payable (see Bye v Coren [1986] STC 393, and Lord Advocate v McKenna [1989] STC 485, 61 TC 688).  We see no reason why HMRC should not be entitled to conduct enquiries and require returns from several potential taxpayers in relation to the profits of the same business.” (AEI Group Ltd v. HMRC [2015] UKFTT 290 (TC), §72, Judge Greenbank).

 

Not open to HMRC to issue one assessment that is paid and then another in respect of the same matter on a different basis

 

“It seemed to be suggested by Mr Nimmo Smith, on the authority of Lord Keith's observations in Bird's case [1988] STC 312 at 321–23, [1988] 2 WLR 1237 at 1249–52 and in particular [1988] STC 312 at 323, [1988] 2 WLR 1237 at 1252, that the Revenue should have elected and chosen at the stage of issuing the notices of alternative assessments, the particular assessment which they intended to insist on. If that be the suggestion we reject it without hesitation. The facts in Bird's case and Garvin's case were completely different to those in the present case. Garvin's case was dealing with a situation where the taxpayer had already been assessed to and paid capital gains tax on the sale of certain shares and he was thereafter charged with income tax on the proceeds of sale thus resulting in double taxation. In Bird's case Lord Keith was agreeing that it was not open to the Revenue to subject a taxpayer to two different charges to tax in respect of the same receipt. These two cases were not concerned with alternative assessments. The very fact that they are alternative in this case, demonstrates that the Revenue will not sue for payment of tax on more than one of them.” (Lord Advocate v. McKenna [1989] STC 485 at 491 per Lord Allanbridge).

 

Alternative assessments only if mutually exclusive

 

“The key distinction with McKenna is that in that case it was a matter of agreement that the various assessments were mutually exclusive: tax was only payable on the same sum once…Collection of PAYE and NIC on payments to employees is not an alternative to self-assessed corporation tax in another entity. They are not mutually exclusive. There is no double taxation on the same income.” (James H Donald (Darvel) Ltd v. HMRC [2017] UKFTT 446 (TC), §§52…53).
 

Alternative assessments

Partnership statements (discovery amendments)

 

“(1)     Where an officer of the Board or the Board discover, as regards a partnership statement made by any person (the representative partner) in respect of any period—

(a)     that any profits which ought to have been included in the statement have not been so included, or

(b)     that an amount of profits so included is or has become insufficient, or

(c)     that any relief or allowance claimed by the representative partner is or has become excessive,

the officer or, as the case may be, the Board may, subject to subsections (3) and (4) below, by notice to that partner so amend the partnership return (including anything included in the return by virtue of section 12ABZB(7)(b) (amendment of partnership return following reference to tribunal)) as to make good the omission or deficiency or eliminate the excess.” (TMA 1970, s.30B(1) – (2)).

 

Meaning of profits

"“profits”—

(a)     in relation to income tax, means income,

(b)     in relation to capital gains tax, means chargeable gains, and

(c)     in relation to corporation tax, means profits as computed for the purposes of that tax;" (TMA 1970, s.30B(9))

Notice of amendment to be given to nominated partner even after the partnership ends

 

“So our finding is that even after the partnership ceased to exist, Mr Bintliff remained the nominated partner in relation to the returns made by the partnership. This means that HMRC were right to give the notice of amendment to Mr Bintliff.” (Phillips v. HMRC [2009] UKFTT 335 (TC), §98).

 

Consequential amendments to partner's tax returns

 

"(2)     Where a partnership return is amended under subsection (1) above, the officer shall by notice to each of the relevant partners amend—

(a)     the partner's return under section 8 or 8A of this Act, or

(b)     the partner's company tax return,

so as to give effect to the amendments of the partnership return." (TMA 1970, s.30B(2))

Assessment time limits apply to consequential amendments


“The death of a partner does not have any time limit consequences for amendments to a partnership statement. But you should treat it as triggering the Section 40 time limits in respect of any consequential amendments required under Section 30B(2) for that partner. In cases where the partnership position has not been finalised a consequential amendment to a deceased partner’s self assessment may become necessary under Section 28B(4) where a Section 12AC(1) enquiry notice has been issued or Section 30B(2) where a discovery amendment has been or may be made under Section 30B(1). In the latter circumstances you should make any Section 30B(2) amendment to the deceased partner’s self assessment within three years of 31 January next following the year of assessment in which the partner died otherwise it will be time-barred.” (EM7301).

No determination if return was in accordance with practice generally prevailing

"(3)     Where the situation mentioned in subsection (1) above is attributable to an error or mistake as to the basis on which the partnership statement ought to have been made, no amendment shall be made under that subsection if that statement was in fact made on the basis or in accordance with the practice generally prevailing at the time when it was made." (TMA 1970, s.30B(3))

Conditions for making amendment

"(4)     No amendment shall be made under subsection (1) above unless one of the two conditions mentioned below is fulfilled.

 

(5)     The first condition is that the situation mentioned in subsection (1) above was brought about carelessly or deliberately by—

(a)     the representative partner or a person acting on his behalf, or

(b)     a relevant partner or a person acting on behalf of such a partner.

 

(6)     The second condition is that at the time when an officer of the Board—

(a)     ceased to be entitled to give notice of his intention to enquire into the representative partner's partnership return; or

(b)     in a case where a notice of enquiry into that return was given—

(i)     issued a partial closure notice as regards a matter to which the situation mentioned in subsection (1) above relates, or

(ii)     if no such partial closure notice was issued, issued a final closure notice,

the officer could not have been reasonably expected, on the basis of the information made available to him before that time, to be aware of the situation mentioned in subsection (1) above.

 

(7)     Subsections (6) and (7) of section 29 of this Act apply for the purposes of subsection (6) above as they apply for the purposes of subsection (5) of that section; and those subsections as so applied shall have effect as if—

(a)     any reference to the taxpayer were a reference to the representative partner;

(b)     any reference to the taxpayer's return under section 8 or 8A were a reference to the representative partner's partnership return; and

(c)     sub-paragraph (ii) of paragraph (a) of subsection (7) were omitted." (TMA 1970, s.30B(4) - (7))

"“relevant partner” means a person who was a partner at any time during the period in respect of which the partnership statement was made." (TMA 1970, s.30B(9))

Exception where grounds for amendment arise out of a claim for overpaid tax

"(1)     This paragraph applies where—

(a)     a claim is made under this Schedule,

(b)     the claimant is one of two or more persons carrying on a trade, profession or business in partnership,

(c)     the grounds for giving effect to the claim also provide grounds for amending, under section 30B(1) (discovery of loss of tax from partnership), a return made by the partnership or any of the partners in respect of any period, and

(d)     such an amendment could be made but for a relevant restriction.

(2)     The following are relevant restrictions—

(a)     the conditions in section 30B(4) to (6), and

(b)     the expiry of a time limit for making an assessment under that section.

(3)     Where this paragraph applies—

(a)     the relevant conditions are to be disregarded, and

(b)     the amendment is not out of time if it is made before the final determination of the claim." (TMA 1970, Sch 1AB, para 7)

Successor of partner

"(10)     Any reference in this section to the representative partner includes, unless the context otherwise requires, a reference to any successor of his." (TMA 1970, s.30B(10))

Partnership statements (discovery amendments)

- Can be used to amend allocation of profit between partners as well as the overall profit

 

"[401] We go further in reaching this conclusion addressing points raised before us.  Section 12AB requires each partner's share of the income to be stated in the partnership statement which forms part of the required return. Section 30B(1) then addresses the position of a discovery of insufficient profits (defined as set out by Judge Fairpo) as regards a partnership statement. The officer may then "make good the deficiency".  A purposive reading of these words enables us to conclude that "making good" the deficiency is wide enough to encapsulate both increasing the amount of "profit" share of partner A and decreasing the "profit" share of partner B.   This reading does not require us to go beyond the words of the legislation in order to conclude that an adjustment mechanism is contained within s30B TMA.    

[402] The structure of the TMA partnership tax provisions is not left with the lacuna HMRC have identified as existing under the Appellant's approach; i.e. the need for HMRC to raise discovery assessments against each individual who had been allocated too little, with no apparent means of correcting the position for the individuals who had been allocated too much (and had paid too much tax).     

[403] We therefore conclude that s30B can be used to make amendments to the allocation of profit between partners as well as amendments of the overall profit." (Boston Consulting Group UK LLP v. HMRC [2024] UKFTT 84 (TC), Judge Bowler)

Pensions: unauthorised payments and scheme sanctions

 

Current position

See the amendment made by FA 2022, s.97, above, which has retrospective effect for some assessments relating to pensions charges.

Not income

 

“An unauthorised payment is not to be treated as income for any purpose of the Tax Acts” (FA 2004, s.208(8)).

 

Companies may be assessed under s.29(1)(a) but not individuals

 

r.4

 

“(1) Section 29(1)(a) of TMA (assessment where loss of tax discovered) applies with the following modification in relation to an assessment to tax under case 1, 2 or 3. 
(2) After “any income” insert— “, unauthorised payments under section 208 of the Finance Act 2004 or surchargeable unauthorised payments under section 209 of that Act or relevant lump sum death benefit under section 217(2) of that Act”. (SI 2005/3454, r.9).

 

“Although that would appear to be an apt provision in this case, it does not apply as regulation 9 restricts the application of the modified s 29 TMA to particular cases, of which Cases 1 and 2 are relevant, as they relate to assessments in respect of unauthorised payments charges and unauthorised payments surcharges.  But those cases apply only where the person liable to the charge is a company (Table 2 in regulation 4 of the 2005 Regulations).  They can have no application where, as in this case, the person assessed is an individual.” (Clark v. HMRC [2017] UKFTT 392 (TC), §14, Judge Berner).

 

Individuals may be assessed under s.29(1)(b)

 

It is not clear why s.29(1)(b) is applicable, but it appears to have been common ground in the following case. XX

 

“In consequence [of restricting r.9 to companies], the relevant limb of s 29(1) is not s 29(1)(a), but s 29(1)(b).  Section 29(1)(a) does not apply because the modification by the 2005 Regulations does not have effect in this case, and there can be no discovery of income as such; by s 208(8) FA 2004, an unauthorised payment “is not to be treated as income for any purpose of the Tax Acts”. (Clark v. HMRC [2017] UKFTT 392 (TC), §15, Judge Berner).
 

But regulation 4 provides a freestanding assessment power for scheme sanction charge

"[39] Regulation 9 does, therefore, give rise to some difficulties for HMRC’s interpretation of Regulation 4. However, our task is to construe Regulation 4 and not to provide a comprehensive explanation for why Regulation 9 is drafted as it is. Our overall conclusion is that Regulation 4 provides a free-standing power to assess the scheme sanction charge arising in these proceedings. We express our conclusion in this limited way since we do not need to decide whether Regulation 4 sets out a freestanding power to assess in all cases (and indeed, as we have noted, determining the source of the power to assess in Cases 1 to 3 is not straightforward given the provisions of Regulation 9).

[40] Our conclusion accords with the ordinary meaning of Regulation 4, as applied to the scheme sanction charge, and avoids what we regard as the illogical outcome for which BFL argues under which, despite Parliament having legislated to impose a scheme sanction charge, HMRC would lack a practical power to assess that charge in many cases...." (HMRC v. Bella Figura [2020] UKUT 120 (TCC), Nugee J and Judge Richards)

Assessment for time limits purposes

"[41(2)] ... A “standalone” assessment of the scheme sanction charge under Regulation 4 remains an “assessment” for the purposes of s34 and s36 of TMA and so remains subject to the time limits set out in those provisions." (HMRC v. Bella Figura [2020] UKUT 120 (TCC), Nugee J and Judge Richards)

Consequential claims for relief or allowance

 

See Chapter C3: Time Limits and late claims

Transfer of allowance to spouse or civil partner

"Where an assessment is made on any person in a case falling within section 36(1) or (1A) or 36A the fact that the person's liability to income tax or total income for any year of assessment is assessed as greater than it was previously taken to be shall not affect the validity of any deduction from net income or tax reduction made in the case of that person's spouse or civil partner by virtue of section 39, 51 or 52 of ITA 2007; and the entitlement in that case of the first-mentioned person for the year in question to any deduction from net income or tax reduction shall be treated as correspondingly reduced." (TMA 1970, s.37A)
