Assumptions used
- HMRC approved mileage allowance payment (AMAP) rates for 2026/27: car or van 55p for the first 10,000 business miles then 25p, motorcycle 24p, bicycle 20p.
- Applies to a vehicle you own or lease personally — not a company car (company cars use HMRC advisory fuel rates instead).
- Passenger payments of 5p per mile per fellow employee can be paid tax-free by an employer, but no relief is available if they are not paid.
- The 10,000-mile threshold applies per tax year for each employment. If you have two or more separate, unassociated employments, each one has its own 10,000-mile band at the higher rate. Associated employments — broadly the same employer, or employers under common control — share a single 10,000-mile band between them (HMRC EIM31280).
- Mileage Allowance Relief reduces your taxable income — the cash you get back is the relief at your marginal rate of tax.
Not sure what mileage you can claim?
We'll email your figures along with the records HMRC expects you to keep — a claim needs mileage logs to support it. If you're claiming through Self Assessment or a P87, we can file it for you.

Estimate only, and relief depends on the journeys qualifying as business travel and on you holding records to support the claim. Excludes company cars and vans (use HMRC advisory fuel rates), ordinary commuting, and mileage already reimbursed as actual running costs. Claiming AMAP rates means you cannot also claim fuel, insurance, servicing or capital allowances for the same vehicle.
