"Where a person has failed to make any returns required under this Act (or under any provision repealed by this Act) or to keep any documents and afford the facilities necessary to verify such returns or where it appears to the Commissioners that such returns are incomplete or incorrect, they may assess the amount of VAT due from him to the best of their judgment and notify it to him."
"19. In my view carelessness can be equated with “negligent conduct” in the context of discovery assessments undersection 29 Taxes Management Act 1970 . In that context, negligent conduct is to be judged by reference to the reasonable taxpayer. The test was described by Judge Berner in Anderson (deceased) v Revenue and Customs Commissioners[2009] UKFTT 206 at [22], cited with approval by the Upper Tribunal in Colin Moore v Revenue and Customs Commissioners[2011] UKUT 239 (TCC) : “ The test to be applied, in my view, is to consider what a reasonable taxpayer, exercising reasonable diligence in the completion and submission of the return, would have done. ” 20. I am satisfied that the effect of paragraph 18 is to remove the liability of a taxpayer to a penalty where: (1) a return is completed and lodged by an agent, and (2) an inaccuracy in the return is the result of something done or omitted by the agent, but (3) the taxpayer took reasonable care to avoid that inaccuracy. 21. What is reasonable care in any particular case will depend on all the circumstances. In my view this will include the nature of the matters being dealt with in the return, the identity and experience of the agent, the experience of the taxpayer and the nature of the professional relationship between the taxpayer and the agent. In my view, if a taxpayer reasonably relies on a reputable accountant for advice in relation to the content of his tax return then he will not be liable to a penalty under Schedule 24 . 22. I am fortified in these conclusions in relation to paragraph 18 by the content of the HMRC Compliance Handbook at CH84540 which states in relation to paragraph 18 as follows: “ A person cannot simply appoint an agent and deny responsibility for their tax affairs. The person still has a duty to take reasonable care, within their ability and competence, to make sure that what they are signing for is correct. The person has to show that they took reasonable care, within their ability and competence, to avoid default by their agent. This will include l making sure that they give the agent all relevant information with which to work . l implementing the professional advice received, and not neglecting some vital step l checking the agent’s work to the extent that the person is able to do so. For example, an ordinary person cannot be expected to challenge specialist professional advice on a complex legal point. But they ought to be able to recognise the complete absence of a major transaction. A person saying and meaning ‘I leave it all to my agent’ is hardly taking care, let alone reasonable care, over their obligations or the work of their agent. .. The person has an obligation to choose an adviser who is trained and competent for the task in hand ... The benchmark is a person who goes to an apparently competent professional adviser l gives the adviser a full and accurate set of facts l checks the adviser’s work or advice to the best of their ability and competence and l adopts it. The person will then have taken reasonable care to avoid inaccuracy on the part of themselves and their agent. ” 23. At one extreme is an error of omission, for example failing to declare a source of income. In those circumstances it seems to me that a taxpayer will almost always be expected to identify the error. At the other extreme an error might involve wrongly construing a complex piece of legislation. In those circumstances the possibility of a penalty may still arise because of the carelessness of the agent, but the taxpayer’s liability to a penalty might well be excluded on the basis that he took reasonable care but did not identify the error. 24. I agree with the general thrust of the guidance given in the HMRC Compliance Handbook. In particular that a taxpayer cannot simply leave everything to his agent. A taxpayer must certainly satisfy himself that the agent has not made any obvious error. That might involve the taxpayer seeking to understand the basis upon which an entry on his return has been made by the agent. However in matters that would not be straightforward to a reasonable taxpayer and where advice from an agent has been sought which is ostensibly within the agent’s area of competence, the taxpayer is entitled to rely upon that advice. At the heart of this issue is the extent to which a taxpayer is required to satisfy himself that the advice he has received from a professional adviser is correct. The answer to that will depend on the particular circumstances of the case."
