From 1 January 2009 HMRC have issued revised fuel rates for car users.

These rates apply when:

employees are reimbursed for business travel in their company cars; or
employers require that employees repay the fuel element of private motoring.
The rates can also be applied to calculate the deemed VAT input tax (included in the fuel element), in mileage rates paid to employees for the business use of their own cars.

The new rates per mile are:

1400cc or less: Petrol 10p, Diesel 11p, LPG 7p.

1401cc to 2000cc: Petrol 12p, Diesel 11p, LPG 9p.

Over 2000cc: Petrol 17p, Diesel 14p, LPG 12p.
