Why did the rate change from 45p to 55p?
The first 10,000 business miles in a car or van pay 55p a mile for the 2026/27 tax year, up from 45p before 6 April 2026. Miles after 10,000 stay at 25p. Motorbikes pay 24p a mile.
Can I claim mileage and also fuel and repairs?
Not for the same vehicle. The flat rate is instead of claiming the actual running costs. Pick one method for each vehicle, and keep to it.
Which trips count as business miles?
Driving for the business, such as to a customer, a supplier or a property you let. Ordinary travel between home and a regular place of work is not a business trip.
When does the 10,000 miles start again?
Each tax year, which runs from 6 April to 5 April. Use the box for miles already claimed if you are part way through the year.
