How does Benefit in Kind (BiK) affect electric cars?

Benefit in Kind (BiK), is often referred to as company car tax. But, the question is, does it affect EVs in the same way as other vehicles?

In this guide to BiK, we chat through:

What is Benefit in Kind tax?

Employees pay Benefit in Kind tax on benefits they get from their employer on top of their salary. HMRC treats the benefit separately from your salary, which means you pay the tax before it arrives in your bank account. Any driver who uses a company car for personal use pays BiK tax out of their monthly wage.

How is Benefit in Kind tax calculated?

Benefit in Kind tax is calculated based on two things: the car’s CO2 emissions and the car’s P11D value. The P11D value is the list price of your car, including VAT, combined with any delivery charges (but doesn’t include the car’s first registration fee or annual road tax).

What are the different Benefit in Kind tax rates?

The BiK rates are calculated based on the car’s CO2 emissions.

Here are the key things you need to know about the BiK rates:

Benefit in Kind remains low for EVs, with an increase of 1% year by year, up until 2027 when it will reach 5%. It will then increase by 2% year on year to 9% in 2029.

How does Benefit in Kind tax on an electric car compare with a hybrid or petrol car?

Though Benefit in Kind for electric cars is increasing over the next five years, it’s staying much lower for EVs than for petrol, diesel, and hybrid vehicles. For non-EVs, it’s increasing quite dramatically.
