HMRC Mileage Rates 2026-27 (from 6 April 2026)
From 6 April 2026 the car and van rate rose from 45p to 55p a mile for the first 10,000 business miles in a tax year - the first change since 2011. The 25p rate above 10,000 miles, 24p for motorcycles and 20p for bicycles are unchanged. These rates apply to sole traders and partnerships using simplified expenses, and to employees claiming tax relief on their own vehicle.
Important: These rates are used for Self Assessment simplified expenses claims for car, van and travel expenses. The 10,000-mile threshold is per tax year (6 April to 5 April) and covers all the cars and vans you use for business. Tax years up to 2025-26 use 45p for the first 10,000 miles; 2026-27 onwards uses 55p. The flat rates apply to cars regardless of fuel, including electric cars you own. Always keep detailed mileage records (dates, routes, business purpose) to support your claim.
How to Claim Your Mileage Allowance
Follow these steps to claim your business mileage tax relief on your Self Assessment tax return:
Keep Detailed Records
Maintain a record of all business miles, including dates, routes, starting points, destinations, and business purpose. You can use a mileage log book, spreadsheet, or specialist app.
Calculate Your Allowable Expense
Multiply your total business miles by the applicable HMRC AMAP rate for your vehicle type. If using a car or van for over 10,000 business miles in a tax year, apply 55p (45p before 6 April 2026) to the first 10,000 miles and 25p to miles above that.
Enter on Tax Return (Box 20)
Log into your Self Assessment tax return on the HMRC website. Under your sole trader income section, find box 20 (simplified expenses for cars and vans) and enter your calculated allowable expense.
Verify Your Tax Savings
HMRC will automatically calculate your tax relief based on your marginal income tax rate. For every pound claimed, you'll save between 0p and 45p in tax depending on your band.
Keep Evidence Safe
Keep your mileage records and vehicle logbook for at least 6 years in case HMRC requests evidence to support your claim. Be honest about business versus personal miles.
Frequently Asked Questions
What vehicle types qualify for AMAP?
The calculator covers cars, vans, motorcycles, and bicycles. Only mileage driven for business purposes (client visits, site work, travelling between locations for business) counts. Commuting to a regular workplace does not qualify.
How does the 10,000 mile threshold work for cars?
For cars and vans, HMRC applies 55p per mile (45p for tax years before 2026-27) to the first 10,000 business miles in each tax year, counting all the cars and vans you use for business together. Each mile above 10,000 is claimed at 25p. For example, 12,000 business miles in 2026-27 is 10,000 x 55p + 2,000 x 25p = £6,000. The count resets on 6 April.
Can I claim actual expenses instead?
Yes. You can choose to claim actual vehicle expenses (fuel, maintenance, insurance, depreciation) if they exceed the AMAP allowance. However, most self-employed traders find AMAP simpler and more generous. You cannot claim both in the same year.
How often do HMRC AMAP rates change?
Rarely. The car and van rate was 45p from 2011 until it rose to 55p from 6 April 2026, the start of the 2026-27 tax year. The 25p, 24p and 20p rates did not change. Claims for 2025-26 and earlier still use 45p for the first 10,000 miles, so pick the right tax year in the calculator. Check GOV.UK for the latest rates.
Do electric cars get 55p a mile?
Yes, if you own the car. The flat mileage rates apply regardless of fuel, so an electric car you own gets 55p for the first 10,000 business miles from April 2026, then 25p, exactly like petrol or diesel. The much lower Advisory Electric Rate is only for company cars.
What mileage evidence do I need?
HMRC expects you to keep records supporting your claim. A simple logbook with dates, destinations, and purpose is sufficient. For claims under £2,500, HMRC is less likely to challenge, but evidence is still advisable. For larger claims, detailed records are essential.
Can employees claim mileage allowance?
Employees can claim if their employer pays them less than the AMAP rate and they drive for work. The claim is made on Self Assessment. However, most employers either reimburse at AMAP or above, making an employee claim unnecessary.
