A person has a company car for a few years and reimburses his employer for all private mileage.
During the 2011/12 tax year, he decides to stop reimbursing his employer and suffer tax on fuel benefit instead.
The new arrangement starts on 1 July 2011.
My question is, can the fuel benefit be pro rated to take account of the period he was still reimbursing his employer? There is no box on the P11D to state when fuel benefit starts, and the software I am using to create the P11D will not let me enter a date in the "fuel benefit started" box unless the car benefit starts on the same date!
Am I missing something?
