The rates per business miles stay the same as last year;
Car: 45p for the first 10,000 business miles in a tax year, then 25p for each subsequent mile, for Tax purposes. 45p for all business miles for NIC’s.
Motorcycle: 24p for all business miles, for both Tax and NIC’s
Cycle: 20p for all business miles, for both Tax and NIC’s
You can pay your employees an ‘approved amount’ of Mileage Allowance Payments (MAPs) each year without having to report them to HMRC. To work out the ‘approved amount’, multiply your employee’s business travel miles for the year by the rate per mile for their vehicle.
