Frequently Asked Questions
What is the HMRC approved mileage rate?
For the 2024/25 tax year, HMRC allows 45p per mile for the first 10,000 business miles in a car or van, then 25p per mile thereafter. Motorbikes are 24p per mile and bicycles 20p per mile.
How do I calculate my mileage expenses?
Enter the number of miles driven for business purposes and the applicable rate per mile. The calculator multiplies these together to give your total claimable expense.
Can I use a custom mileage rate?
Yes. If your employer uses a different reimbursement rate, simply enter that custom rate per mile instead of the HMRC standard rate.
Do I need receipts to claim mileage?
HMRC does not require fuel receipts for mileage claims, but you should keep a mileage log recording dates, destinations, and business purposes for each trip.
