“(1) An enquiry under section 12AC(1) of this Act is completed when an officer of the Board by notice (a "closure notice") informs the taxpayer that he has completed his enquiries and states his conclusions. In this section "the taxpayer" means the person to whom notice of enquiry was given or his successor. (2) A closure notice must either- (a) state that in the officer's opinion no amendment of the return is required, or (b) make the amendments of the return required to give effect to his conclusions. (3) A closure notice takes effect when it is issued. (4) Where a partnership return is amended under subsection (2) above, the officer shall by notice to each of the 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. (5) The taxpayer may apply to the tribunal for a direction requiring an officer of the Board to issue a closure notice within a specified period. (6) Any such application is to be subject to the relevant provisions of Part 5 of this Act (see, in particular, section 48(2)(b)). (7) The tribunal shall give the direction applied for unless satisfied that there are reasonable grounds for not issuing a closure notice within a specified period.”
“(1) The company may apply to the tribunal for a direction that an officer of Revenue and Customs gives a closure notice within a specified period. (2) Any such application is to be subject to the relevant provisions of Part 5 of theTaxes Management Act 1970 (see, in particular, section 48(2)(b) of that Act). (3) The tribunal shall give a direction unless satisfied that an officer of Revenue and Customs has reasonable grounds for not giving a closure notice within a specified period.”
“…Schedule 18, is, I believe, constructed so as to produce a reasonable balance. It imposes obligations on companies to make self-assessments of their own corporation tax liabilities. It gives to the Revenue substantial powers to investigate returns and self-assessments which companies make. Conversely one would expect, and in my view one finds in para 33, a protection for companies that wish to question whether in their particular circumstances the use by the Revenue of some of their Sch 18 powers is, or continues to be, justified.”
“… I see no reason why alternative conclusions should not be stated in a closure notice with the amendment necessarily giving effect to the Revenue’s preferred conclusion. Indeed, if they considered that an individual was liable either to income tax on a trading profit or to capital gains tax, it would seem to be essential that they could keep both options open. There is no need for the appeal system to allow scope for such alternative contentions when they are not stated in the closure notice.”
“It is implicit in the powers given to the general or special commissioners to give a direction requiring the issue of a closure notice, and as part of that ‘reasonable balance’, that a closure notice can be required notwithstanding that the officer has not pursued to the end every line of enquiry or investigation – what is required is that he should have conducted his enquiry to a point where it is reasonable for him to make an informed judgment as to the matter in question, so that, exercising such judgment, he can state his conclusions and make any related amendments to the taxpayer’s return. The exercise of that judgment may require the officer to express his conclusions in broad terms, or even express alternative conclusions [referring to D’Arcy at [12]…”
“…should not be taken as an encouragement to officers of HMRC to draft every closure notice that they issue in wide and uninformative terms. In issuing a closure notice an officer is performing an important public function in which fairness to the taxpayer must be matched by a proper regard for the public interest in the recovery of the full amount of tax payable. In a case in which it is clear that only a single, specific point is in issue, that point should be identified in the closure notice. But if, as in the present case, the facts are complicated and have not been fully investigated, and if their analysis is controversial, the public interest may require the notice to be expressed in more general terms. As both Henderson J and the Court of Appeal observed, unfairness to the taxpayer can be avoided by proper case management during the course of the appeal.”
