Until 31 May 2011 I was employed as loss adjuster for company A, and I drove 4,400 business miles in my own car for that company in 2011/12. I then joined rival company B and drove a further 8,080 miles on business, also in my own car, by 5 April 2012. Both companies paid me 40p per mile for those business journeys. Can I claim anything extra on my tax return?
Yes. The approved tax-free mileage rate for 2011/12 was 45p per mile, for the first 10,000 business miles. However, this mileage threshold applies per employment. As you held two jobs with completely separate employers in the year and drove less than 10,000 miles in each job, all your business mileage can be claimed at 45p per mile. You can claim £624 (5p x 12480 miles) on your tax return for 2011/12.
