“81. When considering a “reasonable excuse” defence, therefore, in our view the FTT can usefully approach matters in the following way: (1) First, establish what facts the taxpayer asserts give rise to a reasonable excuse (this may include the belief, acts or omissions of the taxpayer or any other person, the taxpayer’s own experience or relevant attributes, the situation of the taxpayer at any relevant time and any other relevant external facts). (2) Second, decide which of those facts are proven. (3) Third, decide whether, viewed objectively, those proven facts do indeed amount to an objectively reasonable excuse for the default and the time when that objectively reasonable excuse ceased. In doing so, it should take into account the experience and other relevant attributes of the taxpayer and the situation in which the taxpayer found himself at the relevant time or times. It might assist the FTT, in this context, to ask itself the question “was what the taxpayer did (or omitted to do or believed) objectively reasonable for this taxpayer in those circumstances?” (4) Fourth, having decided when any reasonable excuse ceased, decide whether the taxpayer remedied the failure without unreasonable delay after that time (unless, exceptionally, the failure was remedied before the reasonable excuse ceased). In doing so, the FTT should again decide the matter objectively, but taking into account the experience and other relevant attributes of the taxpayer and the situation in which the taxpayer found himself at the relevant time or times. 82. One situation that can sometimes cause difficulties is when the taxpayers asserted reasonable excuse is purely that he/she did not know of the particular requirement that has been shown to have been breached. It is a much-cited aphorism that ‘ignorance of the law is no excuse’, and on occasion this has been given as a reason why the defence of reasonable excuse cannot be available in such circumstances. We see no basis for this argument. Some requirements of the law are well known, simple and straightforward but others are much less so. It will be a matter of judgement for the FTT in each case whether it was objectively reasonable for the particular taxpayer, in the circumstances of the case, to have been ignorant of the requirement in question, and for how long. The Clean Car Co itself provides an example of such a situation.’”
“32. There are a great many HICBC cases being considered by the Tribunal at present. Many are determined against the taxpayer and a handful have been determined in the taxpayer’s favour. Judge Popplewell in particular appears to have determined a number of cases favourably to the taxpayer and it is on these judgments that the Appellant relies (the most recent is Mark Goodall v HMRC[2023] UKFTT 18 (TC) ) (“Goodall”). In that judgment Judge Poppelwell references his prior decision in Leigh Jacques v HMRC[2020] UKFTT 331 (TC) in which he reviewed the extensive case list on which HMRC rely in HICBC cases. 33. In each of the judgments Judge Poppelwell has concluded that a taxpayer is likely to have a reasonable excuse where: (1) The taxpayer was not under an obligation to complete a tax return up to the tax years prior to that in which the HICBC applied because, primarily, they were paid through PAYE and had no other income justifying a need to notify; (2) child benefit payments were received (either by the taxpayer or their partner) prior to the introduction of HICBC with no children being born post the introduction of the HICBC with the consequence that the application itself made no reference to HICBC (the child benefit claim form post the introduction of HICBC clearly sets out when the charge applies); (3) the taxpayer had not received notification from HMRC directly at any point prior to the contact which led to the issues of the tax assessment; but (4) acted promptly in ceasing to claim child benefit and engaged actively with resolving the historic tax liabilities as soon as HMRC did make contact.”
