Cars/vans: 45p for the first 10,000 miles, 25p after. Guidance only, not tax advice.
HMRC approved mileage rates
If you use the simplified mileage method, you claim a flat rate for every business mile instead of adding up the actual running costs of your vehicle:
| Vehicle | First 10,000 miles | Over 10,000 miles |
|---|---|---|
| Car or van | 45p | 25p |
| Motorcycle | 24p | 24p |
| Bicycle | 20p | 20p |
Worked example
You drive 12,000 business miles in your van: 10,000 × 45p = £4,500, plus 2,000 × 25p = £500. Total claim = £5,000.
Keep a simple log of your business journeys — date, destination and miles — to back up your claim.
