HMRC Mileage Calculator — Calculate Your Mileage Claim
HMRC Approved Mileage Rates
When you use your own vehicle for business travel, you can claim a mileage allowance at HMRC's approved rates — known as Approved Mileage Allowance Payments (AMAPs). These rates are designed to cover the full cost of using your vehicle: fuel, insurance, road tax, and wear and tear.
Current rates: 45p per mile for cars and vans for the first 10,000 business miles in the tax year, then 25p per mile after that. Motorcycles are reimbursed at a flat 24p per mile. Bicycles qualify at 20p per mile. If you carry a fellow employee as a passenger on a business journey, you can claim an additional 5p per mile per passenger.
If your employer reimburses you at less than the approved rate, you can claim Mileage Allowance Relief (MAR) on the shortfall through your self-assessment tax return. If your employer pays more than the approved rate, the excess is treated as a taxable benefit.
Commuting does not qualify. Travel between your home and your regular, permanent workplace is not classed as a business journey. Only trips to temporary workplaces, client visits, or travel between work sites are eligible.
What Counts as Business Mileage?
Business mileage covers travel to clients, customers, suppliers, and temporary workplaces — anywhere you travel in the course of your job rather than simply to your job. Travel between different work sites during the working day also qualifies. Your regular commute from home to your normal workplace does not count, even if your office is far away.
Frequently Asked Questions
What are the current HMRC mileage rates?
For cars and vans, the rate is 45p per mile for the first 10,000 business miles in a tax year, then 25p per mile after that. Motorcycles are 24p per mile and bicycles are 20p per mile, both at a flat rate regardless of distance. You can also claim an additional 5p per mile for each passenger who is a fellow employee travelling on the same business journey.
Does the 10,000 mile limit reset each year?
Yes, the 10,000 mile threshold applies per tax year (6 April to 5 April). At the start of each new tax year, your mileage count resets to zero and you go back to claiming at the higher 45p rate for cars and vans.
Can I claim mileage for my commute?
No. HMRC does not allow mileage claims for ordinary commuting between your home and your regular workplace. You can only claim for business journeys such as visiting clients, travelling between work sites, or going to a temporary workplace.
What if my employer pays less than the HMRC rate?
You can claim Mileage Allowance Relief (MAR) on the difference. For example, if your employer reimburses you at 25p per mile but the HMRC rate is 45p, you can claim tax relief on the 20p difference for each business mile. This is done through your self-assessment tax return.
Do I need to keep records of my mileage?
Yes. HMRC requires you to keep a log of business journeys including the date, destination, purpose of the trip, and miles travelled. You should keep these records for at least five years after the relevant tax year.
