Business Mileage Calculator for Sole Traders
As a sole trader, you can claim HMRC mileage for business journeys in your own vehicle at 55p per mile for the first 10,000 miles in 2026/27. Use the calculator below to estimate your claim from postcodes — no sign-up required.
How sole traders claim mileage
Sole traders use the HMRC simplified mileage rates on the Self Assessment tax return. You multiply qualifying business miles by the rate (55p up to 10,000, 25p above) and enter the total as a business expense. This reduces your taxable profit.
You can only use the simplified rate if you have not already claimed capital allowances for the vehicle. Once you choose the simplified rate for a vehicle, you must keep using it for as long as you use that vehicle for the business.
Which journeys qualify for a sole trader?
Your regular trip to a fixed base of business is ordinary commuting and cannot be claimed, even if you work there full time.
- Visiting clients, customers or suppliers
- Travelling to a job site or project location
- Trips to the bank or post office for business
- Collecting materials or equipment for a job
Worked example
A day like this, five days a week, adds up to roughly £90 a week or £4,680 a year — well within the 10,000-mile threshold at the 55p rate.
