The appropriate percentages are frozen at current rates until 5 April 2025. Thereafter 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.

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 37%.

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.
