Deductible mileage 101 (U.K.)

If you use your car, van, motorcycle, or bicycle for business purposes, you should track your miles. Why? Because driving for business or work is a tax-deductible expense.

The HM Revenue & Customs (HMRC) allows you to write off business drives and permits you to use whichever reliable method you prefer to maintain your mileage log. This includes a paper mileage log, a spreadsheet on a computer, or using a mileage tracking app like MileIQ. 


Mileage Allowance Relief

The Mileage Allowance Relief provides tax relief for employees who use their personal car, van, motorcycle, or bicycle for business purposes. To calculate your Mileage Allowance Relief, track your business mileage for the tax year and multiply it by the applicable rate.

The current HMRC approved mileage allowance payment rates for 2023 are shown in the Business Mileage Rates table below.

Please Note: The Mileage rate does not change each year, however, the fuel reimbursement rate is updated annually


If your employer doesn’t pay you a mileage allowance, you can claim the full approved amount of Mileage Allowance Relief.

If your employer pays you a mileage allowance, but it is less than the approved amount, you can claim Mileage Allowance Relief on the difference.

If your employer pays you more than the approved amount, you’ll have to pay tax on the difference.
