HMRC Mileage Rates 2026/27 Explained

If you're a sole trader or self-employed in the UK and use your personal vehicle for business, you can claim a mileage deduction on your Self Assessment tax return. HMRC sets approved mileage allowance payment (AMAP) rates that cover fuel, insurance, road tax, and wear and tear.

Current HMRC Mileage Rates

Vehicle	First 10,000 miles	Above 10,000 miles
Car or van	45p per mile	25p per mile
Motorcycle	24p per mile (flat rate)
Bicycle	20p per mile (flat rate)

If you carry a passenger who also needs to travel for business, you can claim an extra 5p per mile on top of the standard car rate.

How to Claim Mileage on Your Tax Return

Record every business journey: date, from, to, purpose, and miles driven
Keep a mileage log throughout the year (HMRC can request this)
Enter the total on your Self Assessment return (SA103F, Box 20 — Car, Van & Travel Expenses)
You can only claim AMAP rates OR actual vehicle costs — not both

What Counts as a Business Journey?

Travelling to a client's premises
Visiting a supplier or wholesaler
Going to a temporary workplace
Attending a business meeting or training course

Commuting does not count. Travelling between your home and your regular place of work is not a business journey.

AMAP vs Actual Costs

You have two options for claiming vehicle expenses:

Simplified (AMAP rates) — use HMRC's flat per-mile rates. No need to track fuel, insurance, or servicing separately. This calculator uses AMAP rates.
Actual costs — track every vehicle expense (fuel, insurance, road tax, MOT, servicing, depreciation) and claim the business-use proportion. More complex but can be higher if you drive a lot.

Once you choose a method for a vehicle, you must stick with it for that vehicle. You cannot switch between AMAP and actual costs.

Keep Records — HMRC Can Ask

HMRC requires you to keep mileage records for at least 5 years after the 31 January deadline for the relevant tax year. A mileage log should include the date, start and end points, purpose of the journey, and miles driven.

PocketReceipt's built-in mileage tracker logs all of this automatically — just tap to record each journey, and export a complete mileage report when tax time arrives.
