When a company car is made available for the private use of an employee a 'benefit in kind' value is calculated in relation to the car, and the fuel if that is also provided for private use.

This calculator:

  • allows you to calculate the 'benefit in kind' value of a company car and, if appropriate the car fuel benefit
  • provides an indication of the Income Tax you would be liable to pay for the provision of company car and car fuel benefit

The calculator allows calculations for the years:

  • 2009 to 2010
  • 2010 to 2011
  • 2011 to 2012
  • 2012 to 2013
  • 2013 to 2014
  • 2014 to 2015

Note: There is currently an error in the calculator for 2014-15 for diesel cars with CO2 emissions figures higher than 200g/km. The calculator does not restrict the appropriate percentage to 35% and shows a charge based on a percentage of 38%. This error is being corrected and a revised calculator will be issued as soon as possible.

Information about forthcoming changes is available by following the link below:

If, when using the calculator, you:

  • still see the first screen after entering details into the calculator and pressing 'Next', please scroll to the top of the page to check that you have entered the details for the car and the dates it was available correctly and correct any errors before again pressing 'Next'
  • have difficulty accessing the individual glossary entries, click the 'Glossary' button to gain access to all entries
  • experience problems printing the results pages on the calculator, try setting the page orientation from portrait to landscape
  • encounter any other problems using the calculator, please let HMRC know by using their feedback form and selecting 'Looking for information on HMRC website' from the list
