Why job changes affect your mileage claim
Many employees switch roles during the year, especially in sectors like construction, healthcare and sales. Each employer may pay different mileage rates. If either pays below HMRC’s approved rate, you can claim tax relief on the difference.
How HMRC rates apply
HMRC’s approved rates are 45p per mile for the first 10,000 miles and 25p after that. These apply across your total mileage for the year, regardless of how many jobs you have.
Example of mileage across two jobs
Imagine you drive 3,000 miles for one employer who pays 20p per mile and 4,000 miles for another who pays nothing. In total, you are short 45p on 4,000 miles and 25p on 3,000 miles. That is £2,025 of mileage underpaid. At 20 percent tax relief, you could claim £405.
Backdating your claim
If you changed jobs in previous years and never claimed, you can backdate mileage relief for up to four tax years. This can add up to thousands of pounds in refunds.
