“(7) If a person who, apart from this subsection, would be liable to a surcharge under subsection (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 dispatched, he shall not be liable to the surcharge….”
“(1) For the purposes of any provision of sections 59 to 70 which refers to a reasonable excuse for any conduct – (a) an insufficiency of funds to pay any VAT due is not a reasonable excuse…”
“If the exercise of reasonable foresight and due diligence and a proper regard for the fact that the tax would become due on a particular date would not have avoided the insufficiency of funds which led to the taxpayer’s default, then the taxpayer might well have reasonable excuse for non-payment, but that excuse would be exhausted by the date on which such foresight, diligence and regard would have overcome the insufficiency of funds.”
