Frequently asked questions
How do I calculate my mileage tax rebate?
Our mileage rebate calculator uses HMRC-approved rates to estimate how much tax relief you could claim based on your job, mileage, and employer reimbursement.
Can I claim mileage tax relief if I don’t have exact records?
You do not need a formal logbook to start. A reasonable, honest estimate of your business miles is enough for us to begin, and we will tell you what HMRC needs to support it. Rotas, job sheets, appointment lists and payslips showing mileage payments all help.
How much tax back can I get for mileage in the UK?
It depends on your business miles, what your employer reimbursed and your tax band. Relief is worth your marginal rate of tax on the gap between the HMRC approved rates and what you were actually paid. The average rebate value across our claims is £3,000.
Who can use the mileage rebate calculator?
Anyone. It is built for employed, PAYE workers who use their own car or van for work travel and are paid less than the approved rates. It is free and there is nothing to sign.
Can I backdate my mileage claim using this calculator?
Yes. Enter a single year, then use the four-year figure as a rough guide if your mileage and employment were similar in earlier years. Claims can normally be backdated four tax years, and we check each year individually before we file.
