“(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 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, 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…”
“(1) For the purpose 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; and Where reliance is placed on any other person to perform any task, neither the fact of that reliance nor any dilatoriness or inaccuracy on the part of the person relied upon is a reasonable excuse.”
“…if the exercise of reasonable foresight and of 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 default, then the taxpayer may well have a reasonable excuse for non-payment, but that excuse will be exhausted by the date on which such foresight, diligence and regard would have overcome the insufficiency of funds.”
