“(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 despatched, he shall not be liable to the surcharge . . .”
“ References to service by post Where an Act authorises or requires any document to be served by post (whether the expression “serve” or the expression “give” or “send” or any other expression is used) then, unless the contrary intention appears, the service is deemed to be effected by properly addressing, pre-paying and posting a letter containing the document and, unless the contrary is proved, to have been effected at the time at which the letter would be delivered in the ordinary course of post.”
“You must make sure that your VAT return is received and any payment clears HMRC’s bank account by the due date shown on the return. If you fail to do this you could be liable to a default surcharge (see paragraph 21.2.2 below).”
“The penalty is for failure to file and pay by the due date, not for delay after the due date.”
