The annual benefit for company cars is based on a percentage of the list price. The percentage rate is dependant on the level of CO2 emissions. The rate is 5% for emissions to 50g/km, 9% for emissions 51-75g/km, and 13% for emissions 76-94g/km. The rate increases by 1% for each additional 5g/km above 94g/km to a maximum rate of 37%, reached at 210g/km or more.
There is a diesel supplement of 3% for all bands, subject to a maximum rate of 37%.
Car fuel benefit
£22,100 × ‘appropriate percentage’ (percentage used to calculate the taxable benefit of the car for which the fuel is provided).
The charge is proportionately reduced if provision of private fuel ceases part way through the year. The fuel benefit is reduced to nil only if the employee pays for all private fuel.
