8,000 work miles a year is worth about £2,240

Over 4 tax years at the basic rate. Move the sliders to match your job.

HMRC allows 55p a mile for the first 10,000 miles from April 2026 (45p in the 4 years you can claim now) and 25p after that. You get tax back on the gap between that and what your employer pays you.
