“ 23 (1) Liability to a penalty under any paragraph of this Schedule does not arise in relation to a failure to make a return if P 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 P's control, (b) where P relies on any other person to do anything, that is not a reasonable excuse unless P took reasonable care to avoid the failure, and (c) where P had a reasonable excuse for the failure but the excuse has ceased, P is to be treated as having continued to have the excuse if the failure is remedied without unreasonable delay after the excuse ceased.”
“4 The Act does not say what is meant by a reasonable excuse, and it does not specifically exclude (as other similar legislation does) reliance on a third party from amounting to a reasonable excuse. 5 I cannot, however, see how the failure of the landlord, his solicitors or HMRC to advise Mr Ryan that he should submit a return could conceivably amount to a reasonable excuse. A landlord has no obligation of that kind to his tenant, particularly so when the tenant is represented by a solicitor; and, even if there were an obligation on a landlord's solicitor to advise an unrepresented tenant to submit a return (which I very much doubt) it would be a professional discourtesy for the landlord's solicitor to offer Mr Ryan such advice if he had a solicitor of his own. It may well be correct, as he contends, that HMRC knew of Mr Ryan's existence, and that he had set up in business, but I do not understand how that could impose on them the duty (as Mr Ryan's argument implies) to make a prompt enquiry into his affairs in order to advise him of any requirements imposed on him which he had not then observed. That is not, and never has been, HMRC's function. Moreover, as s 76(3) makes perfectly clear, stamp duty land tax is a self-assessed tax; the obligation to calculate and declare his liability is placed firmly upon the taxpayer. 6 On the other hand I have to agree with Mr Ryan that if he was represented in the transaction by a solicitor, he should be entitled to expect the solicitor not merely to advise him of his obligation to submit a return but to perform the obligation for him. But that is not the same as saying that he has a reasonable excuse, within the meaning of the legislation. The plain purpose of the legislation is to encourage the prompt submission of returns by imposing penalties on those who submit them late. The penalty is imposed on the person concerned, and not upon his solicitor or any other representative. The purpose of the legislation would be defeated if a penalty could be escaped by the expedient of placing the blame on a dilatory solicitor. If Mr Ryan believes he has been let down by his solicitor, his remedy is to take the matter up with the solicitor.”
