There is a diesel supplement of 4% (2020-21: 4%) for all for all diesel cars that are not certified to the Real Driving Emissions 2 (RDE2) standard. The diesel supplement is removed altogether for diesel cars which are certified to the RDE2 standard. The maximum rate including any diesel supplement remains at 37%.

Car fuel benefit
£24,600 × ‘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.
