If you currently use a company car as a work benefit, you are liable to pay tax on it. Company car tax or benefit in kind (BiK) car tax is paid by employees, who are given a company car for personal use, including commuting. This is often through the use of a company car but it can also be a personal or leased car that is paid for by your employer.
How is BiK calculated
Benefit in kind car tax is calculated based on 3 variables:
- P11D value of the car - the list price of your vehicle
- CO2 emissions - the amount of CO2 your car emits
- Income tax band - your personal income tax rate
Benefit in kind (BiK) car tax = P11D value of car x BiK band x income tax rate
In order to make the calculations, you will also need to ascertain the BiK banding of your car. BiK tax bands are based on your car’s CO2 emissions. If you are unsure of your car’s CO2 emissions, HMRC provides a tool where you can check the car fuel and CO2 emissions of all vehicles.

BiK on electric company cars
There is a reduced BiK rate if you have an electric company car. In fact, electric cars enjoy some of the lowest benefit in kind rates. Currently, the benefit in kind (BiK) rate for electric cars is 2%. This rate is set to continue into 2024/2025.
However, the UK government did announce that the rate will increase by 1% in the next 3 consecutive years.
Read our separate guide on compary car tax on electric cars.
BiK on hybrid company cars
For hybrid company cars, the BiK car tax is determined in a similar fashion to conventional vehicles. Since hybrids usually have lower CO2 emissions than petrol cars, you can expect the BiK rate to be lower.
If the car's CO2 emissions are between 1 and 50 g/km, then your benefit in kind rate is based on the vehicle's ‘electric range’ or zero emission mileage figure (see table above).
Low BiK cars
If you are wondering how to make the most out of your benefit in kind tax, it would depend heavily on the kind of car you drive.
For instance, electric cars will give you the lowest BIK as they have the lowest CO2 emissions. Electric models like the Renault Twizy with a £12,000 list price or a SEAT Mii Electric with a list price of £23,000 (lower than average market price on most car models) can also help you keep your benefit in kind tax down.
