How does the Mileage Tax work?

Log all business-related miles traveled in your own vehicle (commute doesn't count).

Apply the 45p rate for the first 10,000 miles.

Apply the 25p rate for any miles thereafter.

Subtract any mileage payment your employer has already made.

The difference is your unclaimed relief, which reduces your taxable income.

Calculated instantly with up-to-date HMRC thresholds. Our engine ensures 100% accuracy for the current tax year.

Pro Tip: Keep your receipts!

Business Miles: This only applies to travel between workplaces or for specific business trips.

Vehicle Types: Different rates apply for motorcycles (24p) and bicycles (20p).

Keeping a Log: You must keep a record of dates, destinations, and distances for every trip.
