It is quite normal practice for employees to be reimbursed at a reasonable mileage rate for business use of their own vehicles. The income tax and national insurance contributions (NICs) position is as follows:
|A statutory system of Approved Mileage Allowance Payments (AMAPs) applies for employees using their own vehicles for business journeys, as follows:
|Cars and vans:
on the first 10,000 miles in the tax year
on each additional mile above this
45p per mile
25p per mile
||24p per mile
||20p per mile
Unless the employee is reimbursed at a rate higher than the AMAP, the payments do not need to be reported on a P11D. If the employer pays less than these rates, it is possible for the employee to claim income tax relief for the shortfall.
Rates of up to 5p per mile, per passenger, are also tax and NICs free when paid for the carriage of fellow employees on the same business trip. This also covers volunteers who drive for hospital car services etc, even though they are not strictly employees.
