In Paul Nowak v HMRC [2019] TC7307 an engineer's claim for travel expense was disallowed: he worked on different contracts not a single contract covering multiple different workplaces. A discovery assessment was allowed on the basis that his accountant had acted carelessly.

The FTT found that the taxpayer was engaged on a separate contract for each job. The only evidence to suggest that each site was a temporary workplace is the fact that Weir paid lodging allowances and mileage allowances without deduction of tax: this was not sufficient on its own to satisfy it that the sites were temporary workplaces. 

The FTT was satisfied that the incorrect claim was brought about by carelessness on the part of the appellant’s accountants whom the appellant had told about the arrangements pursuant to which he was employed. HMRC are therefore entitled to make Discovery assessments for the earlier years under s29 TMA 1970.
