Our guide to HMRC mileage claim in the UK

UPDATED NOV 4, 2021

Welcome to our guide on mileage claim & reimbursement in the United Kingdom. In this guide, you'll find a collection of articles to help you understand HMRC mileage claim rules and regulations. We love to help employees and self-employed individuals create tax-compliant documentation and maximise their savings, mileage allowances, and tax deductions.

How mileage reimbursement works is that some employees or self-employed individuals drive their own cars for personal and business purposes. Business purposes are normally tax-free and therefore one is entitled to receive reimbursement for mileage. Furthermore, companies need to compensate their employees tax-free for business costs incurred in personal vehicles. In many cases, this may also include the cost of gas, but also the cost of maintenance and repairs for the vehicle in question.

How to know if your trip qualifies for reimbursement?

It is simple - if your trip was for business purposes, then you are entitled to claiming mileage based on HMRC rules. What qualifies as a business trip is - you need to be somewhere else rather than the usual workplace to do your job (f.x. conferences or meetings not at your usual workplace), or the job cannot be completed unless a particular trip is made - f.x. picking up supplies for work. 

What does not qualify as a business trip is commuting from your home to your work, or trips that are personal and clearly not for business purposes.
