David Goodall, who was the technical specialist for car benefits at HMRC until last year, has joined fuel and mileage audit company TMC.

He takes the role of head of tax and policy advice. TMC captures and audits fuel and mileage reports for over 100,000 UK business drivers.

As technical specialist, Mr Goodall was responsible for defining HMRC’s official view on the way the law on company car and fuel benefits is applied. Goodall wrote the technical guidance on car benefits in the Employment Income Manual; and wrote additional internet material for fleet users. He was also responsible for the HMRC car and car fuel benefit internet calculator.

"This is a very significant move for TMC," said Paul Jackson, managing director of TMC. "There is increasing pressure on businesses to comply with the letter of car and fuel benefit law and no-one knows the rules better than David. His knowledge is an invaluable asset to our customers and to TMC itself."

Mr Goodall said: "I’m very pleased to be joining TMC at this time. Businesses need to be aware that HMRC is now very focused on the way they record and check mileage claims. They can expect to be challenged over any errors or omissions in their records that might have led, even inadvertently, to underpayments of tax on cars or fuel."
