“the last day of the period of 2 years beginning with the date specified in or for the purposes of column 4 of the Table (that is to say, the last date on which payment may be made without incurring a penalty).”
“(1) A penalty is payable by a person (“P”) where P fails to pay an amount of tax specified in column 3 of the Table below on or before the date specified in column 4. … (4) In the following provisions of this Schedule, the “penalty date”, in relation to an amount of tax, means the day after the date specified in or for the purposes of column 4 of the Table in relation to that amount.”
“In approaching s 59C(2) it is essential, in my view, to bear in mind that it can only come into play when tax has remained unpaid during at least 28 days from the due date. It seems to me that this inquiry which the subsection requires to be made is whether this state of affairs remains in existence on the day after that period has expired. That being the inquiry, I take the view that it has to be answered in respect of a particular point of time, not in respect of the whole of an additional period. In my view that point of time, as a matter of language, is at any time on 29 February. I accept of course that when one is addressing the continuance or otherwise of a state of affairs which has existed during a previous period, that means in practice that one must look to the first moment of the day in question.”
“It is clear from the decision of the High Court that the default (failure to pay tax) has to be tested at a particular moment in time - namely the start of the day following the due date. If the tax is (sic) not been paid by the start of the following day, then there is a default, and a surcharge is payable - even if the tax is paid later on that day. The corollary must be that if the tax is paid by the start of the day following the relevant date, then there is no default, and no surcharge is payable - even if the tax is later refunded by HMRC.”
“The purpose of the surcharge is plainly to encourage taxpayers to pay their tax liabilities on time and to deter late payment.”
