Before we dive into the process, it's crucial to understand that mileage allowance is a tax-free payment made by an employer to an employee to cover the cost of travel in a personal car for business purposes. If you're self-employed, you can claim a proportion of your car running costs as business expenses. Here's how you can navigate the process of claiming mileage back from HMRC.

Understanding Mileage Allowance Rates

HMRC has set specific mileage allowance rates for different vehicle types. These rates cover all your vehicle's running costs, including fuel, insurance, servicing, and depreciation. It's essential to choose the correct rate for your vehicle, as you can only claim up to the approved amount.

Claiming Mileage Allowance for Employees

If your employer pays you a mileage allowance, you don't need to do anything else to claim your tax relief. The allowance is tax-free up to the approved amount. However, if you've received less than the approved amount, you can claim the difference using form P87.

To claim, you'll need to keep a record of your business mileage for at least six years. You can claim for the tax year in which the business travel occurred. If you're unsure about the process, consult your employer or a tax professional for guidance.

Claiming Mileage Allowance for the Self-Employed

If you're self-employed, you can claim a proportion of your car running costs as business expenses. You can either claim the actual costs or use the simplified flat rates. Using the flat rates is more straightforward, as you don't need to keep detailed records of your expenses.

To claim using the flat rates, multiply the business miles you've driven by the appropriate rate. For example, if you've driven 15,000 business miles in a car, you can claim (10,000 miles * 45p) + (5,000 miles * 25p) = £5,250.
