Mileage tax relief

Mileage tax relief is a deduction you can claim on your yearly tax return for any mileage you’ve driven for business purposes. If you use your personal vehicle for business-related driving, you will be eligible to claim mileage tax relief.

Note that if your employer reimburses you for your business mileage at the approved HMRC mileage rates, you are won’t eligible to claim mileage tax relief.

If you are reimbursed by your employer at lower rates than the HMRC approved, you will be able to claim the difference as tax relief on mileage. For example, if you receive 20p per mile, instead of the standard 45p, you will be eligible to claim mileage tax relief at 25p per mile.

Your tax relief on mileage is based on the HMRC approved mileage rates. The rates currently are:

45p per business mile for cars and vans, up to 10,000 miles
25p per mile for over 10,000 miles for cars and vans
24p per business mile for motorcycles
20p per business mile for bicycles

The approved HMRC rates have been unchanged for the past 13 years, so you can use these rates to claim mileage for the previous year too. Calculate the tax relief on mileage by multiplying all business miles you’ve driven throughout the year by the corresponding rates.
