“ (1) P is liable to a penalty, in relation to each tax, of an amount determined by reference to – (a) the number of defaults that P has made during the tax year (see sub-paragraphs (2) and (3)), and (b) the amount of that tax comprised in the total of those defaults (see sub-paragraphs (4) to (7)) (2) For the purposes of this paragraph, P makes a default when P fails to make one of the following payments … in full on or before the date on which it becomes due and payable – (a) a payment under PAYE regulations; (b) a payment of earning-related contributions … … (3) But the first failure during a tax year to make one of those payments … does not count as a default for that tax year. … (8) For the purposes of this paragraph – (a) … (b) A default counts for the purposes of sub-paragraphs 4 to 7 even if it is remedied before the end of the tax year.”
“ (1) If HMRC think it right because of special circumstances, they may reduce the penalty under any paragraph of this Schedule. (2) In sub-paragraph (1) "special circumstances” does not include – (a) ability to pay, or (b) the fact that a potential loss of revenue from one taxpayer is balanced by a potential overpayment by another.”
“(3) …the tribunal may rely on paragraph 9 – (a) to the same extent as HMRC (which may mean applying the same percentage reduction as HMRC to a different starting point), or (b) to a different extent, but only if the tribunal thinks that HMRC’s decision in respect of the application of paragraph 9 was flawed. (4) In sub-paragraph (3)(b) “flawed” means flawed when considered in the light of the principles applicable in proceedings for judicial review.”
“… Special circumstances are either: · uncommon or exceptional, or · where the strict application of the penalty law produces a result that is contrary to the clear compliance intention of that penalty law.”
