My friend has been slapped with a big (£10k+) tax bill from 2008-2011 for car fuel. I'll preface this by saying that I've advised him to get an accountant to fight his corner urgently. Wondered if any MN tax experts can give me a steer in the meantime. He's distraught.
The crux of the matter is that during those years his regular base for work was home but he traveled about once or twice a week to the company HQ 150 miles away. The fuel for those trips was paid for by the company and the mileage was all documented at the time. HMRC are now saying that his regular base for work was the HQ and so the journeys from home are treated as private mileage with any fuel provided taxable. He's since left the company.
Personally, I think there is a case to argue and that, if the company confirm he was home-based, he would not be liable.
Any thoughts?
