Mileage log
For sole traders claiming business miles in a car or van
Log each business journey in your car or van. The log adds up your miles and works out the simplified mileage claim for the tax year you choose: 55p a mile for the first 10,000 business miles in 2026 to 2027 (45p in 2025 to 2026), then 25p. A journey that crosses the 10,000-mile line is split between the two rates.

Where the figures come from
A spreadsheet for organising your own figures. It isn't tax advice, isn't HMRC software and can't send anything to HMRC. Check every figure. Rates and thresholds are for the 2025–26 and 2026–27 tax years (you choose which on the Start sheet) and link to GOV.UK, checked on 18 Oct 2026. If you're not sure what applies to you, ask HMRC or an accountant. Sources and dates are on the Sources tab. Contains public sector information licensed under the Open Government Licence v3.0.
