“P may appeal against a decision of HMRC that a penalty is payable by P.”
“On an appeal under paragraph 13(1) that is notified to the Tribunal, the tribunal may cancel or affirm HMRC’s decision.”
“ Reasonable excuse (1) Liability to a penalty under any paragraph of this Schedule does not arise in relation to a failure to make a payment if P satisfies HMRC or (on appeal) the First-tier Tribunal or Upper Tribunal that there is a reasonable excuse for the failure. (2) For the purposes of sub-paragraph (1) – (a) an insufficiency of funds is not a reasonable excuse, unless attributable to events outside P’s control, (b) where P relies on any other person to do anything, that is not a reasonable excuse unless P took reasonable care to avoid the failure, and (c) where P had a reasonable excuse for the failure but the excuse has ceased, P is to be treated as having continued to have the excuse if the failure is remedied without unreasonable delay after the excuse ceased.”
“ Special reduction (1) If HMRC think it right because of special circumstances, they may reduce a 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 over-payment by another. ….”
“15 … (2) On an appeal …the tribunal may – … (b) substitute for HMRC’s decision another decision that HMRC had power to make. (3) If the tribunal substitutes its decision for HMRC’s, 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 16 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.”
“…to be special the event must be something out of the ordinary, something uncommon; …”
“[53.] We were not referred to (and could not find) any authority on the meaning of "special circumstances". Plainly it must mean something different from, and wider than, reasonable excuse, for (i) if its meaning were confined within that of reasonable excuse, paragraph 9 would be otiose, and (ii) because paragraph 9 envisages a reduction in a penalty rather than absolution, it must be capable of encompassing circumstances in which there is some culpability for the default: where it is right that some part of the penalty should be borne by the taxpayer. [54.] The adjective "special” requires simply that the circumstances be peculiar or distinctive. But that does not necessarily mean that the circumstances which affect all or most taxpayers could not be special: an ultra vires assertion by HMRC that for a period penalties would be halved might well be special circumstances; but generally special circumstances will be those confined to particular taxpayers or possibly classes of taxpayers. They must encompass the situation in which it would be significantly unfair to the taxpayer to bear the whole penalty.”
