How This Works

HMRC AMAP rates: cars/vans 45p/mile for first 10,000 business miles, then 25p/mile. Motorcycles 24p/mile. Bicycles 20p/mile. If your employer pays less than the approved rate, you can claim tax relief on the shortfall via Self Assessment or a P87 form. The relief is the shortfall multiplied by your income tax rate.

Business miles are journeys made in performance of your duties — travelling between different workplaces, visiting clients or suppliers, going to meetings at other sites. Your normal commute (home to your regular workplace) does NOT count as a business mile. If you work from home, travel from home to a temporary workplace can qualify. Keep a mileage log for every business trip — HMRC can request evidence.
