“Every person who- (a) is chargeable to income or capital gains tax for any year of assessment and (b) has not received a notice under section 8 of this Act requiring a return for that year of his total income and chargeable gains, shall, subject to subsection (3) below, within six months from the end of that year, give notice of the Board that he is so chargeable.”
“If any person, for any year of assessment, fails to comply with subsection (1) above, he shall be liable to a penalty not exceeding the amount of tax- (a) in which he is assessed under section 9 or 29 of this Act in respect of that year, and (b) which is not paid on or before 31 January next following that year.”
“(1) Liability to a penalty under any paragraph of this Schedule does not arise in relation to a failure to make a return if the person 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 the person’s control, (b) where the person relies on another person to do anything, that is not a reasonable excuse unless he/she took reasonable care to avoid the failure, and (c) where the person had a reasonable excuse for the failure but the excuse has ceased, he/she is to be treated as having continued to have the excuse if the failure is remedied without unreasonable delay after the excuse ceased.”
“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, decide 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.”
