Liable persons 19 1 Where under this Part— a a reporting cryptoasset service provider or self-certification provider is made liable to a penalty, and b the reporting cryptoasset service provider or self-certification provider is a partnership or trust, the liability to the penalty falls upon a liable person of the reporting cryptoasset service provider or self-certification provider. 2 In paragraph (1), “ liable person ” means, in relation to— a a partnership, a partner of the partnership, b a trust which is not a collective investment scheme, a trustee of the trust, or c a trust which is a collective investment scheme, a trustee, manager or operator of the scheme. 3 In this regulation, “ collective investment scheme ” means any arrangements that are a “collective investment scheme” within the meaning of the Financial Services and Markets Act 2000 . Reasonable excuse 20 1 Liability to a penalty under this Part does not arise if the person satisfies an officer of Revenue and Customs or, on an appeal notified to the tribunal, the tribunal that there is a reasonable excuse for a failure to do anything required to be done under the applicable regulation. 2 For the purposes of this regulation neither of the following is a reasonable excuse— a that there is an insufficiency of funds to do something; b that a person relies upon another person to do something. 3 If a person had a reasonable excuse for a failure but the excuse has ceased, the person is to be treated as having continued to have the excuse if the failure is remedied without unreasonable delay after the excuse ceased. Duplication of liability to penalties 21 1 A UK reporting cryptoasset service provider cannot be liable to penalties under any two or more of regulations 11 (failure to apply due diligence procedures), 12 (failure to comply with record-keeping requirements), and 15 (inaccurate or incomplete reports) in respect of the same act or omission. 2 Where, apart from paragraph (1), a UK reporting cryptoasset service provider would be so liable, the UK reporting cryptoasset service provider is liable to a penalty in respect of that act or omission under whichever of regulations 11, 12, or 15 is, in the opinion of an officer of Revenue and Customs, correct or appropriate in the circumstances. Assessment of penalties by HMRC 22 1 An officer of Revenue and Customs may make an assessment imposing a penalty under any of regulations 11 to 18 and setting it at such amount as, in the opinion of the officer, is appropriate. 2 Notice of an assessment of a penalty under this regulation must— a be given to the person liable to the penalty, b state the date on which it is issued and the time within which an appeal against the assessment may be made, and c in the case of an assessment of a penalty under regulation 11, 12, 14, 15, or 16, state the calendar year in respect of which the penalty is assessed. 3 Subject to paragraph (4), after a notice of assessment of a penalty under this regulation has been given, the assessment must not be altered except on appeal. 4 If it is discovered by an officer of Revenue and Customs that the amount of a penalty under regulation 14(b), 16(b), 17(b) or 18(b) which has been assessed under this regulation is or has become insufficient, the officer may make an assessment in a further amount so that the penalty is set at the amount which, in the opinion of that officer, is appropriate. Time limit and treatment of penalties 23 1 An assessment of a penalty under regulation 12, 14, 16, 17, or 18 must be made within the period of 12 months beginning with the date on which the person became liable to the penalty. 2 An assessment of a penalty under regulation 11, 13, or 15 must be made— a within the period of 12 months beginning with the date on which the inaccuracy, incompleteness or failure first came to the attention of an officer of Revenue and Customs, and b within the period of 6 years beginning with the date on which the reporting cryptoasset service provider or self-certification provider became liable to the penalty. 3 A penalty assessed under regulation 22 is due and payable at the end of the period of 30 days beginning with the day on which notice of assessment is issued. 4 A penalty assessed under regulation 22 is to be treated for all purposes as if it were tax charged in an assessment and due and payable. Right to appeal against penalty assessments 24 An appeal may be brought against a penalty assessment under regulation 22— a on the grounds that liability to a penalty under any of regulations 11 to 18 does not arise, or b as to the amount of a penalty assessed under any of regulations 11 to 18. Procedure on appeal 25 1 Notice of an appeal under regulation 24 must— a state the grounds of appeal, and b be given— i in writing; ii before the end of the period of 30 days beginning with the date on which notice of the assessment under regulation 22(2) was issued; iii to HMRC. 2 Subject to paragraph (3), the provisions of Part 5 of the Taxes Management Act 1970 relating to appeals have effect in relation to an appeal against an assessment under regulation 22 as they have effect in relation to an appeal against an assessment to income tax. 3 On an appeal under regulation 24 that is notified to the tribunal, the tribunal may— a if it appears that no liability to a penalty has arisen, set the assessment aside, b if the amount assessed appears to be appropriate, confirm the assessment, c if the amount assessed appears to be excessive, reduce it to such other amount (including nil) as the tribunal considers appropriate, or d if the amount assessed appears to be insufficient, increase it to such amount not exceeding the permitted maximum as the tribunal considers appropriate. Part 4 Supplementary Anti-avoidance 26 If— a a person enters into any arrangements, and b the main purpose, or one of the main purposes, of entering into the arrangements is to avoid any obligation under these Regulations, these Regulations are to have effect as if the arrangements had not been entered into.
