Company car benefits are based on CO2 emissions data which has encouraged employees to choose diesel cars due to lower CO2 emissions. The government is trying to reduce the number of diesel cars and will increase the current 3% diesel supplement to 4% from 6 April 2018.

As previously announced radical changes to the company car benefit rules are being introduced in 2020. The benefit in kind for electric cars and hybrid cars with a range of 130 miles or more on the electric motor is being reduced to just 2%. That means that the taxable benefit for such a car with a list price of £30,000 would be just £600 a year. Where the employer allows staff to charge their own electric car at work there will be no taxable benefit.
