Employees and directors who are provided with a company car and who also receive some or all of their private fuel from their employers are subject to the fuel benefit charge – on an all or nothing basis. The benefit charge is determined by applying a set multiple to the appropriate percentage for the car, based on its CO2 emissions.

The car fuel benefit charge multiplier will increase from £21,100 to £21,700 with effect from 6 April 2014, notwithstanding the actual fall in fuel prices in the current tax year, so this is another attempt to stop employers providing any private use fuel.
