How it works

Cars and vans: 55p a mile for the first 10,000 business miles in the tax year, then 25p. Motorcycles: 24p a mile.

The flat rate replaces fuel, insurance, repairs and other running costs for that vehicle. You can still claim parking, tolls and train fares on top.

You can’t use flat rates for a vehicle you’ve already claimed capital allowances on, and once you start using them for a vehicle you keep using them while it’s in the business. Keep a record of your business miles. It’s an estimate to help you see the size of the numbers, not tax advice.
