"credit for so much of his input tax as is allowable under section 26, and then to deduct that amount from any output tax that is due from him." 61. Section 25 (3) VATA 1994 provides: "if either no output tax is due at the end of the period, or the amount of the credit exceeds that of the output tax then… the amount of the credit or, as the case may be, the amount of the access shall be paid to the taxable person by the Commissioners…." 62. Section 26 (1) and (2) VATA 1994 provide, in summary, that the amount of input tax for which a person is entitled to credit at the end of any VAT period shall be the amount attributable to taxable supplies made or to be made by the taxable person in the course or furtherance of his business. 63. Regulation 29 VAT Regulations provide for late claims in respect of input tax and for claims for input tax in the absence of a VAT invoice. Regulation 29 provides as follows: 1) Subject to paragraphs (1A) and (2 below, and save as the Commissioners may otherwise allow or direct either generally or specially, a person claiming deduction for input tax under section 25 (2) of [VATA 1994] shall do so on a return made by him for the prescribed accounting period in which the VAT became chargeable…. 2) At the time of claiming deduction of input tax in accordance with paragraph (1) above, a person shall, if the claim is in respect of— (a) a supply from another taxable person, hold the document which is required to be provided under regulation 13 [i.e. a VAT invoice] provided that where the Commissioners so direct, either generally or in relation to particular cases or classes of cases, a claimant shall hold or provide such other . . . evidence of the charge to VAT as the Commissioners may direct. (3) Where the Commissioners are satisfied that a person is not able to claim the exact amount of input tax to be deducted by him in any period, he may estimate a part of his input tax for that period, provided that any such estimated amount shall be adjusted and exactly accounted for as VAT deductible in the next prescribed accounting period or, if the exact amount is still not known and the Commissioners are satisfied that it could not with due diligence be ascertained, in the next but one prescribed accounting period. (4) Nothing in this regulation shall entitle a taxable person to deduct more than once input tax incurred on goods imported or acquired by him or on goods or services supplied to him.* [*Regulation 29 (4) applies with effect from1 April 2009 and, therefore, does not apply to the claims which form the subject matter of this appeal.] 64.Section 121 (2) Finance Act 2008 provides that a trader may make a claim before1 April 2009 for VAT periods ending before1 May 1997 if the claimant held the required evidence in a prescribed accounting period ending before1 May 1997 . 65. Neither party was, rather oddly, able to produce the relevant VAT legislation in respect of exemption and zero-rating as it applied to the relevant to share issues in 1987 to 1989. However, with a little rummaging through the old books, we were able to ascertain the applicable legislation, as follows. 66.
