CH160950 - Reasonable excuse: case law on how to consider reasonable excuse

The Upper Tribunal’s comments in the case of Christine Perrin [2018] UKUT 156 [TC], provide guidance on how the tribunal would approach reasonable excuse.

The following comments are therefore an authority on reasonable excuse.

The correct test for “reasonable excuse”

“69. Before any question of reasonable excuse comes into play, it is important to remember that the initial burden lies on HMRC to establish that events have occurred as a result of which a penalty is, prima facie, due. A mere assertion of the occurrence of the relevant events in a statement of case is not sufficient. Evidence is required and unless sufficient evidence is provided to prove the relevant facts on a balance of probabilities, the penalty must be cancelled without any question of “reasonable excuse” becoming relevant

70. Assuming that hurdle to have been overcome by HMRC, the task facing the FTT when considering a reasonable excuse defence is to determine whether facts exist which, when judged objectively, amount to a reasonable excuse for the default and accordingly give rise to a valid defence. The burden of establishing the existence of those facts, on a balance of probabilities, lies on the taxpayer. In making its determination, the tribunal is making a value judgment which, assuming it has (a) found facts capable of being supported by the evidence, (b) applied the correct legal test and (c) come to a conclusion which is within the range of reasonable conclusions, no appellate tribunal or court can interfere with.

71. In deciding whether the excuse put forward is, viewed objectively, sufficient to amount to a reasonable excuse, the tribunal should bear in mind all relevant circumstances; because the issue is whether the particular taxpayer has a reasonable excuse, the experience, knowledge and other attributes of the particular taxpayer should be taken into account, as well as the situation in which that taxpayer was at the relevant time or times (in accordance with the decisions in The Clean Car Co and Coales).”

The ‘Four-Stage Test’

The judgement in Perrin continues:

“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.”

The Upper Tribunal commented in Marlow Rowing Club v Revenue & Customs, [2020] UKUT 20 (TCC)

“As is clear from the approach to the question of reasonable excuse in Clean Car and indeed in Perrin, the judgment of whether a taxpayer has a reasonable excuse will depend on the evaluation of the particular facts relevant to the taxpayer’s circumstances. There is no benefit in focussing on a selection from the multitude of FTT decisions on reasonable excuse, each of which will turn on their facts, to extract more specific points of principle.”
