“(7) If a person who apart from this sub-section would be liable to a surcharge under sub-section (4) above satisfies the Commissioners or, on appeal, a Tribunal that in the case of a default which is material to the surcharge – (a) the return or as the case may be, the VAT shown on the return was despatched at such a time and in such a manner that it was reasonable to expect that it would be received by the commissioners within the appropriate time limit, or (b) there is a reasonable excuse for the return or VAT not having been so despatched then he shall not be liable to the surcharge and for the purposes of the preceding provisions of this section he shall be treated as not having been in default in respect of the prescribed accounting period in question.”
"The right to deduct input tax was a fundamental principle of the common system of value added tax (VAT) established by the Sixth Directive and member states should not adopt measures designed to preserve the rights of the treasury which undermined the right to deduct VAT. However, the right to deduct did not arise as soon as a claim to deduct was duly made. Moreover, the proposition that the claim itself was entitled to the same protection from derogation by national legislation as an admitted or established right to deduct was not correct. It was settled law that there was a critical distinction between an unadjudicated claim to input tax and an admitted or established claim. Until the claim was accepted or established there was no right to payment. The right under art 17 to deduct input tax had to be exercised in accordance with art 18(1) and (2) and might give rise to a refund. However, it was clear that there was no right to a refund unless the right to deduct was exercised in respect of taxes actually due. Furthermore, as a matter of practical common sense, it was incumbent on the taxable person to satisfy the commissioners of his entitlement to a deduction. Fiscal neutrality required that that should be so and that repayments should not be made to a taxable person who had or showed no such entitlement. It was not sufficient merely to make a claim to be entitled or treated by the law as entitled to have the same protection. Accordingly, there was no prima facie duty on the part of the commissioners to repay input tax until the claim had been agreed or upheld. Capital One Developments Ltd v Customs and Excise Comrs[2002] STC 479 applied. Garage Molenheide BVBA v Belgium (Joined cases C-286/94, C-340/95, C-401/95 and C-47/96)[1998] STC 126 considered."
