A company car is any vehicle (car, van or motorcycle) which is provided to employees by a business. An employee can use the vehicle for business and personal travel.

This article covers

Some businesses include a company car as part of the overall remuneration package for their employees. However, HMRC considers the private use of a company car to be a benefit in kind and is, therefore, taxed as part of the employee’s overall income from employment. The value of the company car benefit in kind (BiK) which is also known as the BiK cash value, is used to calculate the amount of Income Tax the employee must pay and the National Insurance contributions the employer makes to HMRC.

The BiK cash value is calculated using a number of variables, starting with the manufacturer’s list price for the vehicle. The fuel type and carbon dioxide emissions (CO2) are also considered and these determine the BiK percentage which is published by HMRC every tax year. Each tax year, HMRC also adds 4% to the BiK percentage based on other emission factors such as if the vehicle uses diesel fuel.

The overall BiK calculation provides a cash value for the individual vehicle which is included on the employee’s P11D form each tax year. The maximum amount the BiK value can be is 37% of the vehicle list price.

List Price of Vehicle x BIK percentage = BIK cash value

The government wants to encourage electric and ultra-low-emission vehicles and for this reason, the BiK percentage is reduced for vehicles with low and ultra-low emissions. For the 2019/20 tax year, HMRC determined the BiK percentage for these vehicles to be 16% (increased from 13% in 2018/19).

The list price includes the manufacturer’s standard accessories for the vehicle, number plates, and its delivery, with VAT added. Any optional extras, such as metallic paint or higher specification wheels, regardless of the cost, must also be included in the list price.

If any modifications are made to the vehicle, such as fitting an enhanced multimedia system which wasn’t provided by the manufacturer, then these must also be added to the list price, even if the modification is made after its delivery. If any modifications are made in the middle of the tax year, the list price increase will still apply for the whole tax year.

If you make any additional accessory modifications after delivery, which are worth less than £100, then you don’t need to add them to the list price. In contrast, if the accessory was included by the manufacturer before the car was delivered, the cost is included in the list price.

The following example shows the tax liabilities for employers and their employees for a diesel car and an electric car using the manufacturer’s list price and the BIK percentage published by HMRC for the 2019/20 tax year:

For companies with a sole Director and Shareholder, or companies with a small number of employees, it might not be tax efficient to offer a company car. Sometimes claiming mileage for business-related travel is a better option. Crunch clients can find out more about recording and claiming mileage related business travel here.

Our article on company cars can give you a little extra information on whether it’s better for you to choose a company car or to opt for mileage.

For businesses with a higher number of employees, a company car might be necessary because of the employee’s role, such as sales. In this case, it’s wise to consider the fuel type of the vehicle offered to see if it’s for a low or ultra-low emission vehicle.

The tax advantages of providing low or ultra-low emission vehicles are, however, diminishing. The table below shows the benefit in kind cash value of the vehicles from our earlier example for the 2017/18 and 2019/20 tax years and how this has increased.

Car List price CO2 (g/km) 2016/17 BiK Cash value 2019/20 BiK Cash value % Increase in BiK Cash value
Seat Leon (diesel) £25,230 112 £6,055 £7,5691 25%
Seat Leon (petrol) £24,235 112 £5,089 £6,301 24%
Nissan Leaf (electric) £26,490 0 £2,384 £4,328 78%

It’s important to consider different options when deciding to offer or take a company car. What was once regarded as a perk of the job has been firmly in HMRC’s sights to increase its tax revenues for the last 15 years. It’s a good idea to seek advice from your accountant in deciding the best option for your company and personal tax circumstances. If you are a Crunch customer please speak to your client manager.
