How We Calculate This
This calculator applies HMRC approved mileage allowance payment (AMAP) rates to your business miles to calculate the tax-free amount you can claim.
HMRC AMAP rates
- Cars and vans: 55p per mile for the first 10,000 miles, then 25p per mile (55p rate from 6 April 2026)
- Motorcycles: 24p per mile (flat rate, all miles)
- Bicycles: 20p per mile (flat rate, all miles)
- Passenger supplement: 5p per mile per fellow employee carried in a car or van (employer-paid journeys)
The 10,000 mile threshold
The 10,000 mile threshold applies per tax year (6 April to 5 April). Once you have claimed 10,000 miles in a tax year, all subsequent miles are claimed at the lower 25p rate. The calculator tracks how many of your first 10,000 miles have already been claimed.
Tax relief calculation
Tax relief = Total mileage allowance x Your marginal tax rate. The mileage allowance reduces your taxable profit, so your actual tax saving depends on whether you pay basic rate (20%), higher rate (40%) or additional rate (45%) income tax.
Frequently Asked Questions
From 6 April 2026 (tax year 2026/27) the approved mileage allowance payment (AMAP) rates are: cars and vans 55p per mile for the first 10,000 business miles per tax year and 25p per mile thereafter; motorcycles 24p per mile (all miles); bicycles 20p per mile (all miles). An additional 5p per mile can be claimed for each fellow employee carried as a passenger on a shared business journey in a car or van. The 55p rate is the first increase to the car/van rate since 2011 (the over-10,000-mile, motorcycle, bicycle and passenger rates are unchanged).
Yes, but you must choose between claiming mileage allowance OR actual vehicle costs, not both. If you use the simplified mileage method, you claim the HMRC rates and cannot also claim for fuel, insurance, repairs, etc. If you use the actual cost method, you calculate what percentage of your total vehicle costs relate to business use. Once you choose a method for a vehicle, you must stick with it for that vehicle.
Business miles include travel to temporary workplaces (client sites, job locations), travel between job sites during the day, trips to builders merchants or suppliers, and travel to training courses. Commuting from home to a permanent workplace does not count. For tradespeople, most site visits count as business miles since each client site is a temporary workplace.
Keep a log of every business journey including: date, start and end locations, purpose of the journey, and miles driven. You can use a paper logbook, spreadsheet, or a mileage tracking app. HMRC may ask to see your records, so keep them for at least 5 years after the 31 January Self Assessment deadline for that tax year.
Tax relief reduces your tax bill by the mileage allowance multiplied by your marginal tax rate. For basic rate taxpayers (20%), £5,000 of mileage claims saves £1,000 in tax. For higher rate taxpayers (40%), the same £5,000 saves £2,000. Self-employed tradespeople deduct mileage as a business expense on their Self Assessment tax return, reducing taxable profit.
