Calculate Tax on Employees' Company Cars

As an employer, if you provide company cars or fuel for your employees’ private use, you will need to work out the taxable value so you can report this to HM Revenue and Customs (HMRC). 

‘Private use’ includes employees’ journeys between home and work, unless they are travelling to a temporary place of work.

Work Out Taxable Value 

You can calculate taxable value using commercial payroll software.

Or you can use HMRC’s company car and car fuel benefit calculator (external link) if it works in your browser.

Using the HMRC calculator 

Choose fuel type ‘F’ for diesel cars that meet the Euro 6d standard (also known as Real Driving Emissions 2). Choose type ‘D’ for other diesel cars.

Choose type ‘A’ for all other cars.

For electric cars and other cars with CO2 emissions of 75 grams per kilometre or less, answer ‘no’ to the question ‘is the car provided via an optional remuneration arrangement?’.

You can check a car’s CO2 emissions (external link).

Work Out the Value Manually 

You can also work out the value manually on P11D working sheet 2 (external link). You will have to use this method if both of the following apply during the tax year you’re reporting on:

  • the car was unavailable for at least 30 consecutive days 
  • you were providing fuel for private use, but stopped doing this
