HMRC Mileage Rates Calculator UK 2026
Calculate your mileage claim for business travel using the official HMRC approved rates for 2026/27. Covers car (55p/25p), motorcycle (24p), bicycle (20p), and passenger allowances. See your tax relief at each rate.
HMRC's approved mileage allowance payment (AMAP) rate for cars is 55p per mile for the first 10,000 business miles in a tax year, then 25p per mile thereafter. If your employer pays less than these rates — or nothing at all — you can claim the difference as tax relief through your self-assessment return or form P87.
The first-10,000 car rate rose from 45p to 55p on 6 April 2026, the first change since 2011/12 and the end of a long-running complaint from motoring organisations that the rate had not kept pace with fuel costs. If you are claiming for 2025/26 or any earlier year, use 45p. Motorcycles still attract 24p per mile and bicycles 20p per mile, with no reduction after 10,000 miles. You can also claim 5p per mile for each passenger you carry on the same business journey, provided they are travelling for business purposes.
HMRC processed 740,000 mileage-related tax relief claims via form P87 in 2022/23 (HMRC Employment Income Statistics, 2024). This calculator applies the correct AMAP rates to your business miles and shows the tax relief you can claim at your marginal rate.
