Work miles could mean
tax back.

Use your own car for work and get paid less than 55p a mile? See the tax you can claim back for every open year, check your mileage log against HMRC’s evidence rules, and get the right form and deadline.

Check your figures, see how to claim, and keep a clear plan for each year.
