As part of its drive to encourage green motoring, the government has introduced a new emissions test, as well as new car benefit percentages. The scale of charges for working out the taxable benefit for an employee who has use of an employer provided car is computed by reference to bands of CO2 emissions multiplied by the original list price of the vehicle. The maximum charge is capped at 37% of the list price of the car.
In 2017, the government announced that cars registered from April 2020 will be taxed based on the Worldwide harmonised Light vehicles Test Procedure (WLTP). Legislation has now been passed to amend the previously planned benefit percentages for 2020/21 through to 2022/23.
