Calculate your approved mileage allowance payment using HMRC’s 2025/26 rates. Whether you’re employed (claiming from your employer or HMRC) or self-employed (deducting from profit), this calculator shows exactly what you’re entitled to.
HMRC mileage rates 2025/26
HMRC sets “Approved Mileage Allowance Payment” (AMAP) rates — the maximum amount that can be paid tax-free. These rates have not changed since 2011 despite significant increases in fuel and running costs.
| Vehicle | First 10,000 miles | Over 10,000 miles |
|---|---|---|
| Cars and vans | 45p per mile | 25p per mile |
| Motorcycles | 24p per mile | 24p per mile |
| Bicycles | 20p per mile | 20p per mile |
| Passengers (additional) | 5p per mile per passenger | 5p per mile per passenger |
Self-employed people can either use the simplified mileage method (45p/25p HMRC rates) or claim actual costs (fuel, insurance, tax, MOT, depreciation — in proportion to business use). For most people with modern cars, the mileage method is simpler and often more generous. Once you choose actual costs for a vehicle, you must continue with actual costs for that vehicle’s lifetime.
Employees: claiming Mileage Allowance Relief (MAR)
If your employer pays you less than the HMRC approved rate, you can claim the difference (called Mileage Allowance Relief or MAR) as a tax deduction via Self Assessment or a P87 form. For example: if your employer pays 25p per mile and you drive 8,000 business miles, you’re paid £2,000 but the HMRC approved amount is £3,600 — you can claim relief on the £1,600 shortfall. At 40% tax, that’s £640 back.
If your employer pays more than the HMRC approved rate, the excess is taxable as income and must be declared.
