How HMRC Mileage Allowance Works

1

Track your miles

Record every business mile you drive. Start and end odometer readings or GPS tracking both work.

2

Calculate your allowance

45p per mile for the first 10,000 and 25p per mile after. This covers fuel, insurance, and wear and tear.

3

Deduct from profit

Your mileage allowance is subtracted from gross income before tax is calculated, reducing your bill.
