Car benefit charge

Appropriate percentage for calculating the taxable benefit of petrol, hybrid, electric, bi-fuel and other alternatively fuelled company cars.

The appropriate percentages were frozen between 2022/23 and 2024/25, after which the percentages for cars with emissions of less than 75 g/km will rise 1% each year for three years, up to a maximum of 5% for electric cars and 21% for other ultra-low emission cars. The percentage for all other cars will increase by 1% in April 2025, up to the maximum of 37%, and will then be frozen for two further years.

In 2028/29 the percentages for zero emission cars will increase to 7%, with the percentages for all cars with emissions between 1 and 50 g/km increasing to 18% regardless of their zero emission range, and the percentages for all other cars increasing by 1% up to a maximum of 38%.

In 2029/30 the percentages for zero emission cars will increase to 9%, with the percentages for all cars with emissions between 1 and 50 g/km increasing to 19% regardless of their zero emission range, and the percentages for all other cars increasing by 1% up to a maximum of 39%.

Where a CO₂ emissions figure is not a whole number it should be rounded down to the nearest whole number, and if an electric range figure is not a whole number it should be rounded up to the nearest whole number.

All cars propelled solely by diesel are subject to a 4% supplement unless they meet the Real Driving Emissions Step 2 (RDE2) standard. However, the maximum appropriate percentage cannot exceed the maximum rates noted above.

Under the legislation governing Optional Remuneration Arrangements, for agreements made from 6 April 2017 if a cash allowance is offered but a company car is selected, should the CO₂ emissions of the company car exceed 75 g/km, the car benefit charge will be the greater of the annual cash allowance and the cash equivalent of the company car. When calculating the cash equivalent to be compared against the cash allowance employee contributions should be ignored.

Similar rules apply for salary sacrifice, where the amount of salary sacrifice would be compared against the cash equivalent of the company car.
