10p mileage allowance increase
The government has announced a 10p increase to the amount of tax relief drivers can claim when they use their own cars for business journeys. What's the full story?
The mileage allowance has been set at 45p per mile for the first 10,000 miles since 6 April 2011. Trade unions have been campaigning for an uplift, and today, a long overdue increase has been confirmed. The mileage allowance has been increased by a modest 10p per mile for the first 10,000 miles, bringing it to 55p per mile, with all other rates remaining static.
The increased rate is also being backdated to 6 April 2026. Where an employer reimburses an employee for the cost of using their own car for business journeys, the mileage allowance sets the amount that can be reimbursed tax-free. Whereas if an employer either does not reimburse employees, or reimburses them at a lower rate, then tax relief on the difference can be claimed.
