Mileage claim calculator
Enter your annual business miles in a car or van to see your HMRC mileage claim: 55p a mile for the first 10,000 business miles, then 25p (35p from 6 April 2027). It also shows a rough tax saving at the 20% basic and 40% higher rates.
This is record-keeping information, not tax advice. Check GOV.UK for your own situation, or ask an accountant.
How the claim is worked out
For 2026–27, GOV.UK lists approved mileage rates for cars and vans of 55p a mile for the first 10,000 business miles in the tax year and 25p for each business mile over 10,000 (GOV.UK). The same figures are the simplified expenses rates for sole traders (GOV.UK).
From 6 April 2027 the rate for business miles over 10,000 rises from 25p to 35p (GOV.UK: Budget 2026). Tick the box to see the 2027–28 figure. For example, 12,000 business miles comes to £5,500 plus £500, so £6,000, at the 2026–27 rates, and £5,500 plus £700, so £6,200, from 6 April 2027.
About the tax saving figure
The tax saving is a rough guide only: it’s the claim multiplied by 20% and by 40%, the basic and higher rates listed on GOV.UK: Income Tax rates and allowances. What you actually save depends on your income and tax band, and it doesn’t include National Insurance.
- Employees: if your employer pays you a mileage allowance, GOV.UK says to take that away first. Relief is on the difference. See the Mileage Allowance Relief guide.
- Scottish taxpayers: Scottish Income Tax has different bands and rates, so the 20% and 40% figures won’t match yours (GOV.UK: Scottish Income Tax).
- Motorcycles and bicycles: this calculator is for cars and vans. The rates are on the HMRC mileage rates 2026–27 page.

Questions
How is an HMRC mileage claim worked out?
Multiply your first 10,000 business miles in the tax year by 55p, and each business mile over 10,000 by 25p. From 6 April 2027 the rate over 10,000 miles is 35p. So 12,000 miles is £6,000 now and £6,200 from 6 April 2027.
Is the tax saving figure what I’ll actually save?
No, it’s a rough estimate: the claim multiplied by 20% or 40%, before National Insurance. Your real saving depends on your income and tax band, and employees should take off any mileage allowance their employer pays first. Scottish rates differ.
Does the calculator work for motorbikes or bicycles?
No, it’s for cars and vans. GOV.UK lists 24p a mile for motorcycles and 20p for bicycles, whatever the mileage.
