2021 Guide: UK Tax on Company
Cars Explained

Company vehicles are subject to various and specific tax regulations. Find out here exactly how to calculate your company car tax and how to pay it.

Calculating Company Car Tax in the UK

As it stands there are two parts to calculating UK company car tax. The first part is what the company pays. The second part is what the employee pays. These amounts are dependents on the car’s value, CO2 emissions and the employee’s income-tax bracket.

The amount of company car tax paid by the company is determined by the car’s P11D value and its CO2 emissions.

For employees calculating car tax is a little more complicated. The amount of tax an employee pays is the P11D value multiplied by the Benefit-in-Kind band multiplied by the employees tax bracket (P11D value) x (BiK band) x (tax bracket).

P11D & Tax on Company Vehicles

When it comes time to calculate company car tax it is important to become familiar with P11D. The P11D form is completed by the employer and given to HMRC for company car tax purposes. This form tells HMRC how much National Insurance a company needs to pay for all the benefits and expenses they provided during the year. This includes any cash benefits like interest-free loans, private healthcare and of course, company cars.

Further detailed information regarding P11D forms and calculating company car tax can be found here.

Company Car Tax For UK Employers Explained

If you are an employer who provides a company car benefit to your employees you must report the car or fuel costs to HMRC. All employers are responsible for paying a tax on company vehicles if these benefits are provided as part of a salary sacrifice arrangement.

A salary sacrifice arrangement is an agreement between a company and employee to reduce an employee's entitlement to cash pay in return for a non-cash benefit, like a company car.

Companies need to report to HMRC if they:

  • Provide employees with company cars used for private journeys
  • Provide or pay for fuel for private journeys

Things to keep in mind regarding tax on company vehicles: company cars face variable tax rates which are based on their CO2 emissions. Company vans and light commercial vehicles are categorized into one classification for calculating company car tax.

Company Car Tax for Employees
Explained: BIK

If an employee or their family uses a company vehicle for personal use they are required to pay a tax on company car usage. This company car tax is referred to as a BIK tax, or Benefit in Kind tax. HMRC views any private usage of a company car as a taxable benefit. This includes using the vehicle for commuting to work.

The company car tax calculations are dependent on the employee’s earnings, the cost of the car, and the amount of carbon dioxide emissions (CO2) comes out of the vehicle's exhaust.

Exemptions From Tax on Company Vehicles

Some employees are exempt from paying BIK taxes on their company vehicles. If you drive a company car, as opposed to a company van, you may be exempt from company car tax if you are:

  • A Partner of a Partnership or a Limited Liability Partnership (LLP)
  • A proprietor of your own business
  • Driving a company car that is adapted for mobility and disability reasons
  • Driving a company car used purely for business reasons in which the car is usually left on the business property overnight and on weekends
  • Driving a company car that is a pool car

Tax on Company Cars vs Company Vans

Most of the rules are the company car tax rules are the same for vans as they are for cars. However, there are a few more exemptions for vans. As with a company car, employees do not have to pay a tax on company vans if the vehicle is used only for business purposes or is a pool van.

According to HMRC a business journey is considered a trip that is made as part of work, like traveling between appointments or a trip to a temporary workplace. HMRC says that a van can be used for private journeys by the employee if the trip is insignificant. Employees will not be required to calculate company car tax on trips that include stopping to purchase a coffee or newspaper on the way to a job.

How to calculate UK company car tax

Employers are required to provide their employees with a copy of the P11D form by July 6, following the end of the tax year. Employees are suggested to to keep those forms as they may be needed to complete a tax return or to claim a repayment of tax.

The amount of tax on company vehicles an employee pay depends on:

  1. The employees income tax band
  2. The vehicle’s CO2 emissions
  3. List price of the vehicle, cost of delivery, VAT and any optional extras
  4. What type of fuel the vehicle takes
  5. How often the employee uses the vehicle

How it works:
The company car tax is calculated by determining the P11D value. This value is the sum of the vehicle’s list price and extra costs (excluding road tax or first-year registration fees) multiplied by the BiK band percentage. The amount paid is that sum multiplied by the employees income tax band 20%, 40% or 45% for residents of England and Wales. Or multiplied by 19%, 20%, 21%, 41% or 46% for residents of Scotland.

Allowance for Taxes on Company Car

Instead of a company car, some employees are given a company car allowance. A company car allowance is a cash allowance that is added to the annual salary of the employee.

This allowance allows the employee to buy or lease a vehicle themselves. Company car allowances are not subjected to company car taxes. Instead the money is taxed at the normal income tax rate.

Fuelling Your Company Car

In addition to the company car some businesses will cover the cost of fuel as well. This fuel benefit is taxed separately from the company car tax. Further information on company car tax explained and how to calculate fuel tax can be found on the HMRC government website.

Company car tax code

What is a company car tax code?

This is the tax imposed on any company, on employees. However, they are different types of taxes in different regions. This type of tax is cut depending on the employees' tax bracket, which is then multiplied by the P11D value and lastly multiplied by the benefit in kind.

What does the car tax code look like?


It contains a tax code which the company gives its employees and a cut from one’s personal earnings, which is also referred to by HMRC as a benefit in kind, depending on the salary an employee gets. There is a group rate off that shows the cut you will get from your salary; the higher your salary is, the higher the tax charged.

Why is the company car tax code important?

The car tax code is very important as the company's value and benefits determine the tax. It helps in estimating the tax expected to be cut to save on financial use.
