Power to make determine tax due
​
"(1) Where it appears to the Board that a transfer of value has been made or where a claim under this Act is made to the Board in connection with a transfer of value, the Board may give notice in writing to any person who appears to the Board to be the transferor or the claimant or to be liable for any of the tax chargeable on the value transferred, stating that they have determined the matters specified in the notice." (IHTA 1984, s.221)
"(2) The matters that may be specified in a notice under this section in relation to any transfer of value are all or any of the following—
(a) the date of the transfer;
(b) the value transferred and the value of any property to which the value transferred is wholly or partly attributable;
(c) the transferor;
(d) the tax chargeable (if any) and the persons who are liable for the whole or part of it;
(e) the amount of any payment made in excess of the tax for which a person is liable and the date from which and the rate at which tax or any repayment of tax overpaid carries interest; and
(f) any other matter that appears to the Board to be relevant for the purposes of this Act." (IHTA 1984, s.221)
​
Transfers of value include those arising from conditionally exempt transfers and trees/underwood

(c) disposals on which tax is chargeable under section 126 of this Act,
or to the amounts on which tax is then chargeable." (IHTA 1984, s.221)
​
Determination to be based on return if correct, otherwise to best judgment
​
"(3) A determination for the purposes of a notice under this section of any fact relating to a transfer of value—
(a) shall, if that fact has been stated in an account or return under this Part of this Act and the Board are satisfied that the account or return is correct, be made by the Board in accordance with that account or return, but

(IHTA 1984, s.240(1))
​
"(1) The Board shall not take any legal proceedings for the recovery of any amount of tax or of interest on tax which is due from any person unless the amount has been agreed in writing between that person and the Board or has been determined and specified in a notice under section 221 above.
(2) Where an amount has been so determined and specified but an appeal to which this subsection applies is pending against the determination the Board shall not take any legal proceedings to recover the amount determined except such part of it as may be agreed in writing or determined and specified in a further notice under section 221 above to be a part not in dispute.
(3) Subsection (2) above applies to any appeal under section 222 above but not to any further appeal; and section 222 above shall have effect, in relation to a determination made in pursuance of subsection (2) above, as if subsections (4) to (4B) of that section were omitted." (IHTA 1984, s.242(1))

(a) the date on which the payment (or in the case of tax paid by instalments the last payment) was made and accepted, and
(b) the date on which the tax or the last instalment became due;
and at the end of that period any liability for the additional tax and any Inland Revenue charge for that tax shall be extinguished.

"(1) This section applies in a case within section 240(2) which involves a loss of tax in relation to a chargeable transfer, where—
(a) the lost tax involves an offshore matter, or
(b) the lost tax involves an offshore transfer which makes the lost tax significantly harder to identify.
(2) Proceedings for the recovery of the lost tax may be brought at any time not more than 12 years after the later of the dates in section 240(2)(a) and (b).
(3) Lost tax “involves an offshore matter” if it is charged on or by reference to property which is situated or held in a territory outside the United Kingdom at, or immediately after, the time of the chargeable transfer.
(4) Lost tax “involves an offshore transfer” if—
(a) it does not involve an offshore matter, and
(b) the property is transferred to a territory outside the United Kingdom at a relevant time.
(5) In subsection (4)(b) “relevant time” means a time after the chargeable transfer but before—

(a) HMRC was significantly less likely to become aware of the lost tax, or
(b) HMRC was likely to become aware of the lost tax only at a significantly later time.
(7) But proceedings may not be brought under this section if—

(b) an agreement to which the United Kingdom and that territory are parties, with or without other parties.
(9) This section is subject to any provision of this Act which allows for a longer period for the bringing of proceedings." (IHTA 1984, s.240B)
​
- Other cases (including no account delivered): 20 years
​
"(6) Subsection (7) applies to any case not falling within subsection (2) where too little tax has been paid in respect of a chargeable transfer, provided that the case does not involve a loss of tax brought about deliberately by a person liable for the tax (or a person acting on behalf of such a person).

​
IHT paid in accordance with prevailing view of the law: no further tax can be demanded​
"Where any payment has been made and accepted in satisfaction of any liability for tax and on a view of the law then generally received or adopted in practice, any question whether too little or too much has been paid or what was the right amount of tax payable shall be determined on the same view, notwithstanding that it appears from a subsequent legal decision or otherwise that the view was or may have been wrong." (IHTA 1984, s.255)
​
- Must be view of the law that is viewed generally as being likely to be correct or adopted in practice, rather than simply well known
"[86] In my view:
(1) It is likely that, in choosing to use the term "received" the legislature intended s 255 to apply where the relevant view of the law is viewed generally (by relevant persons) as being correct or, at least, likely to be correct, and not merely where the view of the law is well publicised and generally known to relevant persons. That is a well-known and understood meaning of "received" when applied, in effect, to a state of knowledge or way of doing something. I note HMRC's contention that the legislature would have used the term "accepted" (or something similar) if this test was meant to have the meaning I ascribe to it. However, I consider that this interpretation reflects a natural, plain meaning of "received" (as in "received wisdom") whereas HMRC's interpretation does not sit well with any natural meaning of the term. It would be an odd use of language to refer to a well-publicised view of the law which is accessible and known to relevant persons by using the one word reference to a "received" view of the law.
(2) (a) I do not accept that applying the received test in this way involves any particular difficulty as it requires consideration of the relevant persons' subjective views of the relevant view of the law; that can be determined by an objective assessment of the available evidence such as commentary in the textbooks and other published materials and the actions of relevant persons, and (b) As Mr Ewart said, it is reasonable to suppose that the legislature intended to set the bar somewhat higher than would apply on HMRC's interpretation, given that the effect of s 255 applying may be that tax is due at a higher or lesser amount than would be due on the correct view of the applicable law. It would be very surprising if the effect of this provision were that HMRC could, in effect, override the law as correctly interpreted, if their official view is not in accordance with that, simply where that official view is published and widely known, even if it were thought generally by relevant persons to be incorrect.
(3) As the parties were agreed, the adopted test requires consideration of what course of action people took, in real life situations, as regards the relevant view of the law. On its natural meaning, the term carries the connotation that the view of the law must be taken on board in a positive sense that it is used, followed, or acted in accordance with in a way which shows it was viewed as correct or highly likely to be correct. To my mind, as Mr Ewart submitted, taking a course of action which it is thought would achieve the desired result without falling within the parameters of the relevant view of the law, thereby avoiding a potential conflict with HMRC, does not amount to adopting that view in the required positive sense the use of that term implies. The same point made in (2)(a) applies here also and similarly to the point made in 2(b), given the nature and effect of the provision, I consider it reasonable to suppose that the legislature did not intend HMRC's view of the law to override the actual law unless relevant persons generally acted on it on the basis it is correct/highly likely to be correct.
(4) Overall, whilst there may be some overlap between the two tests, essentially the difference appears to be that (a) the focus under the received test is on whether the relevant view of the law is generally accepted by relevant persons as correct/highly likely to be correct as a theoretical matter of intellectual analysis, and (b) the focus under the adopted test is on whether the relevant view of the law is accepted as correct/highly likely to be correct by relevant persons as demonstrated by the actions they take in practice."

- Insufficient evidence that practitioners agreed with HMRC's stated view or adopted it in practice
"[90] I do not accept, however, that the evidence demonstrates, as HMRC submitted, that by 2013 the majority of practitioners agreed with the stated view albeit that they evidently gave it consideration when advising taxpayers how to conduct their affairs. There is little evidence that the stated view was accepted as correct or likely to be correct and/or as an authoritative statement of the law. Rather, the weight of opinion appears to have been that the correctness of the stated view was doubtful.
...
[102] It is not reasonable to make an assumption that the stated view was adopted in practice from the fact that there is little other evidence of taxpayers adopting an inconsistent view:
(1) I note that Mr Ryder only has one example, other than the Barclays case, of a taxpayer initially adopting a position which was contrary to the stated view, and I accept that the evidence establishes that (a) practitioners would advise taxpayers to make disclosure to HMRC if they took a course of action contrary to a published view, such as the stated view, if that occurred in relation to an event requiring an account to HMRC, (b) HMRC would be likely to pick up any instances of a contrary view being taken when a report was made to them for IHT purposes, and (c) due to the nature of his position Mr Ryder would be likely to be aware of relevant challenges by taxpayers.
(2) However, overall the evidence of the witnesses is that (a) the addition of property was a rare occurrence. Non-domiciled settlors were routinely advised to contribute property to their settlements before they became deemed domiciled and the "entry charge" which would apply in many instances was a disincentive, and (b) even if there was an addition of property, that would not necessarily require an account to be made for IHT purposes if the view was taken that, contrary to the stated view, it was relevant property. On that basis, it cannot be assumed that the absence of known challenges to the stated view demonstrates that it was being adopted in practice.
(3) I note that before 2006 settlors could add property into many settlements without an entry charge and there is some evidence that this was not a frequent occurrence. However, I do not consider that it can be assumed that the stated view was, as HMRC submitted, the main or a significant factor in influencing individuals not to add property before 2006, given that the evidence is that (a) there are other reasons influencing individuals' relevant choices as to how to deal with their valuable assets (see the evidence of Ms Chamberlain in particular), (b) the precise extent to which property was added is simply not known, and (c) the rarity of additions of property, whether before or after 2006, was at least to some extent because settlors were advised to and did add property whilst they were non-domiciled. For the reasons already given, on the correct interpretation of s 255, advising on and/or taking that course of action of itself that does not show that the stated view was adopted in practice.
(4) I accept that, as HMRC submitted, it is reasonable to assume that advisers/taxpayers would act on the basis of advice given in the leading textbooks which discussed the stated view. However, for the reasons already set out, the comments made in the textbooks do not demonstrate that the majority of authors regarded the stated view as correct/likely to be correct and to the extent authors gave advice on action to be taken, such action does not amount to the adoption of the stated view in practice."
