Mileage allowance relief calculator

If you use your own car, van, motorbike or bicycle for work journeys and your employer pays you less than HMRC's approved rate a mile, you can claim tax relief on the difference. Enter your business miles and what your employer pays. The calculator shows the relief for this tax year and for as many as 4 years before it.

How this was worked out

1. 2026/27: approved mileage rates
2. Approved amount: 6,000 miles × 55p + 0 miles × 25p = £3,300.00
3. Your employer paid: 6,000 miles × 25p = £1,500.00
4. You can claim: £3,300.00 − £1,500.00 = £1,800.00
5. Tax relief: £1,800.00 × 20% basic rate = £360.00
6. 2025/26: approved mileage rates
7. Approved amount: 6,000 miles × 45p + 0 miles × 25p = £2,700.00
8. Your employer paid: 6,000 miles × 25p = £1,500.00
9. You can claim: £2,700.00 − £1,500.00 = £1,200.00
10. Tax relief: £1,200.00 × 20% basic rate = £240.00
11. 2024/25: approved mileage rates
12. Approved amount: 6,000 miles × 45p + 0 miles × 25p = £2,700.00
13. Your employer paid: 6,000 miles × 25p = £1,500.00
14. You can claim: £2,700.00 − £1,500.00 = £1,200.00
15. Tax relief: £1,200.00 × 20% basic rate = £240.00
16. 2023/24: approved mileage rates
17. Approved amount: 6,000 miles × 45p + 0 miles × 25p = £2,700.00
18. Your employer paid: 6,000 miles × 25p = £1,500.00
19. You can claim: £2,700.00 − £1,500.00 = £1,200.00
20. Tax relief: £1,200.00 × 20% basic rate = £240.00
21. 2022/23: approved mileage rates
22. Approved amount: 6,000 miles × 45p + 0 miles × 25p = £2,700.00
23. Your employer paid: 6,000 miles × 25p = £1,500.00
24. You can claim: £2,700.00 − £1,500.00 = £1,200.00
25. Tax relief: £1,200.00 × 20% basic rate = £240.00
26. Total relief: £360.00 + £240.00 + £240.00 + £240.00 + £240.00 = £1,320.00

Was this right and useful?

Yes No

What the calculator assumes

• You are an employee using your own vehicle, not a company car, and you do not fill in a Self Assessment tax return.
• You drove the same business miles, were paid the same rate a mile and paid the same rate of Income Tax in every year you claim for.
• The miles are work journeys only. Your normal commute does not count.
• You paid at least as much Income Tax as the relief in each of those years.
• The rates of tax are this year's. Some Scottish rates were a little different in earlier years.

How the relief works

HMRC sets an approved amount a mile that covers the cost of owning and running a vehicle. For a car or van it is 55p a mile for the first 10,000 business miles in the 2026/27 tax year, and 25p a mile after that. In earlier tax years the first 10,000 miles were paid at 45p. The rate is 24p a mile for a motorbike and 20p for a bicycle.

If your employer pays less than that, the gap is called mileage allowance relief. It comes off the pay you are taxed on, so you get back the gap multiplied by your rate of Income Tax. With the example figures above the calculator, the relief is £360 for this tax year and £1,320 with the four years before it. If your employer pays the full approved amount or more, there is nothing to claim.

Which journeys count

Business miles are journeys you make for your job, such as visiting patients, clients or other sites. Travel between home and your normal place of work is commuting and never counts. A trip to a temporary place of work, such as a site you go to for a short project, can count.

You cannot claim for fuel, repairs, vehicle tax or an MOT on top of the rate a mile, because the approved amount already covers them.

How to claim

You can claim yourself with HMRC's online service on GOV.UK. You need a mileage log for each year: the reason for every journey and the postcodes where it started and ended. For this tax year HMRC usually changes your tax code; for earlier years it changes your tax code or sends you a refund. If you fill in a Self Assessment tax return, you claim on the return instead.

The uniform tax rebate calculator works out another claim many of the same workers can make. To see your pay after tax, use the take-home pay calculator, and the tax code checker explains the new code HMRC gives you after a claim. NHS staff can see their pay for each band on the NHS pay calculator, and the money guides cover other ways tax works on pay.

What it leaves out

• Company cars, where you can only claim for fuel you paid for yourself.
• Passenger payments and other travel costs, such as parking or tolls.
• Years in which you paid less Income Tax than the relief.

Official guidance

• Claim tax relief for your job expenses: vehicles you use for work on GOV.UK
• Expenses and benefits: business travel mileage for employees' own vehicles on GOV.UK
