Can I Claim Mileage Tax Relief for Working at Multiple Sites?
If you use your own vehicle to travel between different work locations, you may be eligible for a mileage tax rebate. This applies whether you're a construction worker moving between sites, a nurse visiting patients, or a tradesperson working on various jobs. In this guide, we'll explain when mileage becomes tax-deductible, what counts as a temporary workplace, and how to claim your rebate.
What qualifies as business mileage?
Business mileage includes any travel you do for work that is not part of your normal commute. You can usually claim tax relief if:
You travel between different job sites
You move between temporary workplaces
You use your own car or van for these journeys
You cannot claim for travel between home and a permanent office or site.
What is a temporary workplace?
HMRC considers a site temporary if you:
Work there for less than 24 months
Expect to be assigned elsewhere once the job ends
For example, a tradesperson working at a new housing development for 8 months, or a care worker visiting different patients in their homes.
How much can I claim?
If your employer does not reimburse you, or pays you less than the full approved rate (currently 45p per mile for the first 10,000 miles), you may be able to claim tax relief on the shortfall.
Typical mileage rebates range from £300 to £2,500 depending on your job, miles travelled, and how many years you’re claiming for.
Do I need to track every trip?
Not necessarily. If you have a general work pattern or regular route, services like TaxBax can estimate your mileage based on job type and number of days worked.
How do I claim?
You can claim mileage tax relief directly from HMRC, or use a rebate service like TaxBax to handle the process. Most people are eligible to claim back up to 4 years.
