“a reasonable excuse should be judged by the standards of reasonableness which one would expect to be exhibited by a taxpayer who had a responsible attitude to his duties as a taxpayer, but who in other respects shared such attributes of the particular appellant as the tribunal considered relevant to the situation being considered”
“It is clear that, in enacting paragraph 16 of schedule 55, Parliament intended to give HMRC and, if HMRC’s decision is flawed, the Tribunal a wide discretion to reduce a penalty where there are circumstances which, in their view, make it right to do so. The only restriction is that the circumstances must be ‘special’. Whether this is interpreted as being out of the ordinary, uncommon, exceptional, abnormal, unusual, peculiar or distinctive does not really take the debate any further. What matters is whether HMRC (or, where appropriate, the Tribunal) consider that the circumstances are sufficiently special that it is right to reduce the amount of the penalty.”
“85. In our view, there is a reasonable relationship of proportionality between this legitimate aim and the penalty regime which seeks to realise it. The levels of penalty are fixed by Parliament and have an upper limit. In our view the regime establishes a fair balance between the public interest in ensuring that taxpayers file their returns on time and the financial burden that a taxpayer who does not comply with the statutory requirement will have to bear. 86. In view of what we have said about the legitimate aim of the penalty scheme, a penalty imposed in accordance with the relevant provisions of Schedule 55 FA 2009 cannot be regarded as disproportionate in circumstances where no tax is ultimately found to be due. It follows that such a circumstance cannot constitute a special circumstance for the purposes of paragraph 16 of Schedule 55 FA with the consequence that it is not a relevant circumstance that HMRC must take into account when considering whether special circumstances justify a reduction in a penalty.”
