Company Vehicle Benefit in Kind (BIK) 2020

Benefits in Kind (BIK) are benefits which directors or employees receive from employment which are not included in their salary or wages. Sometimes these are also called "perks" or "fringe benefits". A company car is seen as a major perk by the taxman: and as soon as you use it for a personal reason (including commuting), it is viewed as a taxable payment.

The below table illustrates rates for cars registered after 6th April 2020

To calculate how much tax you'd have to pay on a company car please use the method below:

  • Get your car's P11D value: list price combined with VAT, delivery, cost options, & registration.
  • Multiply the P11D value by the vehicle's company car tax rate (illustrated in the table above) to get your Benefit in Kind amount.
  • Multiply your Benefit in Kind amount by your personal tax rate to get your company car tax payable.
