“(1) Subject to the provisions of the Corporation Tax Acts, in computing the amount of profit to be charged under Case I or II of schedule D no sum shall be deducted in respect of ... (d) any sum expended for repairs of premises occupied, or for the supply, repairs or alterations of any implements, utensils or articles employed for the purposes of the trade or profession beyond the sun actually expended for those purposes; ... (f) any capital withdrawn from, or any sum unemployed or intended to be employed in the trade profession or vocation…”
"This was originally regulated by the Rules of schedule D of the 1842 Act which provided what deductions were, and what were not, to be allowed in the case of expenditure on plant”” and quoted the provisions of Rule 3 of schedule D of the 1842 Act. He did not consider the provisions relating to the prohibition of deduction for capital items. He continued, "
“The Rule only permits deduction of items “expended” for the supply repairs, or alteration of any implement, utensil or article to the extent of the sum actually expended”
"Now I think that Rule recognises that the repair of premises and the supply and repairs of implements etc are legitimate deductions from annual revenue, subject to this - and this seems to me and this seems to be what clause is specially designed to secure - that the allowance shall be no more than the average of the three preceding years."
"I think that the provision prohibition enjoined under section (d) is not against any deduction for recurring expenditure on repairs on and renewals, but is directed only against the deduction of a larger sum than is ascertained on a three year's average of such expenditure."
"These restrictions operate negatively: that is to say they are restrictions on an implicit right to deduct sums expended for repairs being of course sums which were wholly and exclusively laid out for the purposes of the trade... the effect of the words ... is to limit the deduction to sums actually expended during the relevant year of account ..."
"(a) the amount paid, or liable to be paid, is excessive by reason of a mistake in calculating the claimant’s liability to corporation tax, and (b) liability was calculated in accordance with practice generally prevailing at the time."
"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."
