Disclaimer

UK Mileage Calculator provides general calculations based on published HMRC mileage rates. It is not HMRC, and the results are not tax, accounting or legal advice.

Journey eligibility matters

The calculator does not determine whether a journey is ordinary commuting, private travel or qualifying business mileage. Enter only mileage that qualifies under the rules that apply to you.

Self-employed users

Simplified vehicle expenses have eligibility conditions. For example, the method may not be available for a vehicle where capital allowances or certain actual vehicle costs have already been claimed. Limited companies cannot use the self-employed simplified-expenses scheme.

Employee relief

The Mileage Allowance Relief and tax-saving figures are estimates based on the reimbursement and tax rate entered. Your actual entitlement and tax saving can depend on your full circumstances and how a claim is made.

Check important claims

Before submitting a tax return or tax-relief claim, compare the result with current GOV.UK guidance or obtain professional advice where necessary.
