About the UK Mileage Allowance Calculator
HMRC's approved mileage allowance payments (AMAP) are 45p a mile for the first 10,000 business miles in a tax year and 25p after that for cars and vans, 24p for motorcycles and 20p for bicycles. Employers can pay these tax-free.
If your employer pays less, you can claim Mileage Allowance Relief on the difference through form P87 or Self Assessment. If they pay more, the excess is taxable. Driving to your normal workplace is commuting and does not count.
