Benefit in kind (BIK) refers to a tax on various perks that companies provide to their employees, such as company cars or medical insurance. The term “company car tax” specifically refers to a tax on the benefits of using a company car for business and personal use.

A key advantage of an electric company car is that employees can benefit from considerable savings on their company car tax. Company car tax on an electric vehicle is much lower than for petrol or diesel cars.

This guide will explain what benefit in kind (BIK) tax is and how to calculate company car tax. In addition, this guide will explain how drivers with a company car can reduce their company car tax when they have an electric vehicle.

How is company car tax calculated?

The amount of company car tax an employee pays is based on three main factors:

Company car tax is usually deducted from an employee’s gross monthly income pay.

Why is company car tax lower for electric car drivers?

As discussed above, BIK tax bands are calculated based on a vehicle’s carbon dioxide emissions.

Good news for EV drivers. Pure electric vehicles have zero exhaust emissions. Therefore, the BIK tax band on electric cars is very low (2%). 

BIK tax bands are expected to remain low for EVs. Between 2023-2025, the BIK tax for full-electric cars is expected to stay at 2%. This is significantly lower than the BIK rates for petrol and diesel vehicles – which can be as high as 37%.

How do you calculate company car tax?

The calculation for company car tax is as follows:

(P11D value of a car x BIK tax band percentage) x income tax bracket percentage

An example comparing company car tax on an electric and diesel car:

Let’s look at an example of the average company car tax for a pure electric car:

P11D value of a pure electric company car: 30,000.

BIK tax band of an electric company car: 2%.

Income tax bracket: 30%.

(30,000 x 0.02) x 0.30 = £270 a year of company car tax on an electric car.

Let’s look at an example of the average company car tax for a diesel car:

P11D value of a diesel company car: 30,000.

Average BIK tax band of a diesel car: 31%.

Income tax bracket: 30%.

(30,000 x 0.31) x 0.3 = £2790 a year of company car tax for a diesel car.

Use this HMRC calculator to figure out the amount of tax for your company car.

Is the BIK rate different for pure electric vehicles and hybrids?

Yes, the BIK tax rate is higher for hybrid cars than for pure electric cars. However, the BIK tax band is often lower; therefore, company car tax is often cheaper for hybrid vehicles than petrol or diesel vehicles.
