How is the Mileage Allowance Relief Calculated?

Mileage claims are calculated by multiplying your business-related mileage throughout the tax year with the applicable HMRC mileage rate.

For example, 

You have driven 12,000 business miles over the tax year using your own car.

10,000 * 45p = £4,500

2,000 * 25p = £500

Total you can claim = £5,000

What Records are to be Kept for Mileage Allowance Relief?

In order to claim mileage allowance, individuals must keep accurate records of all business-related travel, including the following:

  • Date of travel
  • The start and end address of each trip, including postcodes
  • Number of miles traveled
  • The purpose of the journey.

These records will be needed if the individual is ever audited by the HMRC.

How to Claim Mileage Allowance Relief?

Once you have calculated your mileage expenses and have all the necessary documentation, you can claim the mileage allowance through a Self-Assessment tax return.

By filling out the tax return and including the mileage allowance as a claim, you will be able to deduct that expense from your taxable income and potentially lower the amount of tax you owe.
