Mileage Calculator FAQ
Everything you need to know about claiming business mileage, HMRC rules, and tax relief in the UK.
For cars and vans, the HMRC Approved Mileage Allowance Payment (AMAP) rate is 45p per mile for the first 10,000 business miles in a tax year, and 25p per mile thereafter. For motorcycles, the rate is 24p per mile. For bicycles, the rate is 20p per mile.
Yes. If your employer reimburses you at a rate lower than the HMRC AMAP rate, you can claim tax relief on the difference. For example, if your employer pays 30p per mile, you can claim tax relief on the remaining 15p per mile (for the first 10,000 miles).
Yes, HMRC requires you to keep accurate records of your business journeys. Your log should include the date, start and end locations, purpose of the journey, and the number of business miles travelled. This is essential for self-assessment or if HMRC requests evidence.
No. Ordinary commuting between your home and your permanent workplace is not considered business mileage and cannot be claimed. Business mileage only applies to journeys made in the performance of your duties, such as visiting clients or travelling between temporary workplaces.
