How the AMAP mileage claim is worked out
HMRC's Approved Mileage Allowance Payments let you claim a fixed rate per business mile instead of tracking actual fuel and running costs. For a car or van, the rate is 45p per mile for the first 10,000 business miles in the tax year, dropping to 25p per mile after that. Motorcycles are a flat 24p per mile and bicycles a flat 20p per mile, neither has a mileage threshold. You can also claim an extra 5p per mile for each passenger who is a fellow employee travelling with you on a business journey. If your employer pays you less than the AMAP rate per mile, you can claim Mileage Allowance Relief (MAR) on the shortfall, the difference between what AMAP allows and what you were actually paid, through a tax return or a P87 form.
