Many companies have recognised the value of providing a company car as part of employee benefits. This can be an appealing perk for both employers and employees, as the vehicle can be used for personal and business purposes. However, this benefit comes with tax obligations, which we’ll explain in this blog.

Company Car Overview

When your employer provides a company car, HMRC treats this as a Benefit in Kind (BiK). This means that even if the car is only used for commuting, you will be liable to pay tax on this benefit.

What is a Benefit-in-Kind (BiK)?

A Benefit-in-Kind refers to non-cash perks provided by your employer, such as the use of a company car, which are subject to tax in addition to your salary.

Factors Affecting the Tax You Pay

The tax owed for a company car depends on several factors:

  • The list price of the car as stated by the manufacturer (P11D value).
  • Your annual income.
  • The type of fuel used by the car and its carbon dioxide (CO2) emissions.

Diesel vehicles are subject to a 4% surcharge, whereas petrol and electric vehicles do not attract this extra charge.

Company Car Tax Bands for 2024/25

The tax payable on your company car is determined by its “company car tax band,” which is based on the vehicle’s CO2 emissions. Below is a table outlining the BiK tax bands for non-electric cars for the 2024/25 tax year.

How to Calculate Company Car Tax

To calculate the tax you owe on your company car, follow these steps:

  1. Find the car’s P11D value, which includes the list price, delivery fees, and the first year’s road tax.
  2. Multiply the P11D value by the appropriate BiK rate based on the car’s CO2 emissions.
  3. Apply your income tax rate to the result.

Example of Company Car Tax Calculation

Let’s say you drive a Mercedes C-Class with a P11D value of £40,000 and CO2 emissions of 147g/km. Based on the table, the BiK rate for this car in the 2024/25 tax year would be 34%. The taxable amount is:

£40,000 x 34% = £13,600

If you fall into the higher income tax bracket of 40%, your tax liability would be:

£13,600 x 40% = £5,440

If you’re still uncertain, you can use HMRC’s online calculator to work out the exact tax payable for your specific company car.

Reducing Your Tax Liability

The government is actively promoting the use of electric vehicles by offering lower tax rates compared to petrol and diesel cars. Below is a table that shows potential tax savings for different types of vehicles:

As demonstrated, opting for an electric vehicle such as the Tesla Model 3 can lead to significantly lower tax compared to hybrid, petrol, or diesel options.

Conclusion

When choosing between an electric, hybrid, petrol, or diesel vehicle, it’s essential to consider the tax implications. Your income tax bracket also affects the overall tax payable on your company car, so it’s important to calculate potential costs in advance.
