OFFICIAL MILEAGE RATE INCREASES TO 55p
The announcement sees the official rate increase from 45p to 55p for the first 10,000 miles, with no change to the 25p rate above this mileage threshold.
This is the first rise in 15 years and what this means is for the self-employed, you just need to use the higher rate of 55p when preparing your 2026/27 tax return next year – no action is needed until then.
For employees, your employer is not obliged to pay the higher rate, and not all will do so. In this case, you can claim a refund from HMRC – to get tax relief on the difference between what your employer pays you and the 55p rate. However, this is only tax relief, at 20%, 50% or 45% – not the full 100% amount of the difference.
