“… apart from a closure notice, and the power to correct obvious errors or omissions, the only other method by which the Revenue can impose additional 30 tax liabilities or recover excessive reliefs is under the new s29. That confers a far more restricted power than that contained in the previous s29.”
“…the word “discovers” does connote change, in the sense of a threshold 35 being crossed. At one point an officer is not of the view that there is an insufficiency such that an assessment ought to be raised, and at another he is of that view. That is the only threshold that has to be crossed. We do not agree that the lawyer, in Lord Denning’s example, would be regarded as having made a discovery any the less by waking up one morning with a different 40 7 conclusion from the one he had earlier reached, than if he had changed his mind with the benefit of further research. It is, we think, evident that the relevant threshold for there to be a discovery may be crossed as a result of a “eureka” moment just as much as by painstaking research.”
“228.In other words, from the first, we find Mr Clarke was of the view that as a matter of law, Mr Atherton’s self assessment did not include 30 the loss relief claim. It is clear from his letters and actions that he held this view despite the completion of box 20 and the fact that the self-assessment calculation incorporated the claim. 229.The evidence clearly shows that HMRC only realised that the self-assessment was insufficient following the decision in Cotter when it 35 was made plain that a claim for carried back losses which was included in a self-assessment was not a standalone claim, but simply an invalid claim leading to an insufficient self-assessment.”
“…[HMRC’s] understanding of the law up until Cotter led them to 20 conclude that the self-assessment in law was, or had to be treated as being, for£2 million and therefore was not insufficient despite in practice the self-assessment on its face including the invalid loss relief claim, and being expressed to be nil. Mr Clarke discovered in early 2014 that his view of the law was wrong and that the self-assessment 25 in law was for nil and was therefore insufficient.”
“For the purposes of this Act a loss of tax or a situation is brought about carelessly by a person if the person fails to take reasonable care 5 to avoid bringing about that loss or situation.”
