Benefit in Kind for Cars


When organisations provide a benefit to their employees, HMRC class it as a Benefit in Kind (BIK). Cars fall into this too, so drivers need to pay something called Company Car Tax, also known as Benefit in Kind tax. When you quote for a car on our website, it’ll include the correct amount of Benefit in Kind. The amount is based on the CO2 emissions, any additional options, fuel types and value. It is also based on your income tax bracket.

For electric cars, Benefit in Kind tax is only 2% until 2025, rising by only 1% each year until 2028. This means you can make considerable tax savings when choosing an ultra low emission vehicles.

Although the idea of Benefit in Kind tax for company cars might sound confusing, fear not as experts in this area we have prepared a handy guide to help.

In this article we will cover:

What is Benefit in Kind?

Benefits in Kind applies to any benefits which you receive from your company in addition to your salary. These are sometimes called ‘perks’ and can include anything from private medical insurance that’s paid for by your employer, to childcare vouchers and company cars.

Not all benefits in kind are taxed. For example, subsidised public bus services or bicycles provided to an employee to and from their workplace do not trigger BIK tax.

As an employee, you need to pay tax on your company car if you or your family use the car privately in any capacity, this includes commuting. This tax is deducted by your employer through Pay As You Earn (PAYE).


What is P11D?

A P11D form is a HMRC document used by an employer to report certain expenses and benefits paid for or made available to employees. It is a form that needs to be submitted annually.

It gives HMRC details of any benefits in kind which are not included in the payroll and subject to PAYE and NIC (National Insurance Contribution) deduction throughout the year.

With this in mind, when we talk about P11D values below, you just need to remember that it means the value of the benefit which you have to pay tax on.


How is Benefit in Kind calculated?

Unless you use your company car solely for business purposes, not including commuting, it is classed as a BIK and therefore you need to pay tax on it.

How much tax you pay is dependent on the following:

For cars with more than 75g/Km CO2, the taxable benefit is calculated based on the higher value of either the gross salary sacrifice amount or the Benefit in Kind value.

For low emission cars (those with less than 75g/Km CO2), there are three main steps to calculating your BIK:
