What is BIK tax?

If you're lucky enough to be supplied with a company car then you could be liable to pay a charge known as Benefit in Kind (BIK) tax. The amount you're required to pay will depend on three things:

  • Price of your vehicle (P11D value)
  • Your annual earnings
  • CO2 emissions of the vehicle

As with all taxes, the rules change often. Recent changes from 6th April 2020 aim to provide the most accurate possible calculation of emissions.

It’s important to know that the smallest change to the options on a vehicle, even something as seemingly insignificant as adding mats, can impact the amount of tax that needs to be paid. If you're in any doubt about the rate that will apply to your chosen vehicle, be sure to get in touch with HMRC to confirm.

How is BIK tax calculated?

BIK tax is calculated by using your car’s P11D value and its BIK tax band. If you don't know these, use the HMRC tax calculator to work out how much you will pay on a company car.

For example, an Audi A4 with a P11D value of £30,000 and emissions of 130g/km would have a BIK tax band of 25%. The BIK would be 25% of £30,000 (£7,500) and this would be charged at the marginal rate of tax – either 20% or 40%, making the annual charge £1,500 or £3,000 respectively.

What affects BIK?

Different factors can affect BIK tax, such as your fuel choice and your mileage. If you aren’t sure how much you should pay, use the HMRC calculator.

BIK tax for vans

Tax on your van depends on whether you use it purely for business or for both business and personal reasons.

If you are an employee and regularly use your van for private use, then you must pay BIK tax.

Vans currently have a flat rate of BIK which is £3,430. If your company also pays for your fuel, usually with a fuel card, there is an additional BIK standard value of £655. Zero emission vans pay 60% of the rate, meaning an employee is liable to pay £2,058.

Employees also pay a percentage of the BIK value based on their own personal tax obligations. If you pay 20% tax, you pay 20% of the BIK value. Standard tax payable on a van is therefore £686 which is just £57.17 per month. The same applies to the fuel benefit tax and for zero emission vehicles.

BIK tax for electric cars and hybrids

The Government introduced new BIK savings on efficient battery electric cars and plug-in hybrids from 6th April 2020 in a bid to increase the uptake of fully electric cars among fleets.

Company car drivers will now pay 0% tax on pure electric vehicles (EVs) throughout 2020/21.
