Company Car Tax Calculator: UK

Calculating your company car tax can be a tricky task, as you’ll need to know the Co2 and the P11d values of the vehicle, along with your tax band. Luckily we have a solution to help.

We've teamed up with Comcar to build the below calculator that allows you to work out everything you need to know about company car tax and any tax implications of driving a company car.

How does our Company Car Tax Calculator work?

Our Company Car Tax Calculator takes into account various factors to provide you with an accurate estimate of your tax liability. Here's how it works:

  1. Vehicle details: Begin by entering the details of the company car you drive or are considering. This includes the make and model as well as the fuel type, then click Go. You can then select the exact edition of the car you have for even more accurate results.
  2. Employee contributions: You can then enter any employee contributions that you make to your company car, such as any capital contribution up to the maximum of £500. Any initial payment by the driver will reduce the price of the car for tax purposes applied to that driver. There’s also the option to add any payments made for private use. If your employer requires an annual private use contribution towards the car, enter the amount to reduce the payable tax.
  3. Add extra vehicle options: The Add Vehicle Options button allows you to mention any optional extras that have been fitted to the basic vehicle, such as driver assistance systems, interior equipment, paint, seats, wheels, warranty and more. This is because company car tax considers the fully configured vehicle, and these optional extras can affect the price. Once done, click Quick Tax Calculation.
  4. Tax calculation: Once you have entered all the required information, our calculator will generate a detailed breakdown of your company car tax liability via vehicle benefit tax and fuel benefit tax figures across the upcoming tax year periods. This includes things like the P11D value, percentage charge, Benefit in Kind amounts, tax payable at the basic rate and tax payable at 40%.
  5. View the effect on net pay: There’s also the option to find out how a company car will alter your net pay. Here you can enter your annual salary and add any contributions as well as the vehicle registration date, and the calculator will give you a figure on how much additional tax you can expect to pay from the use of the vehicle. You can change the data to show a breakdown for different tax years too for a thorough tax breakdown and detailed forecast. The calculator will give you a “Total on payslips” figure too, so you can see exactly how much you’ll be taking home each year after tax.
  6. Make an enquiry: After reading through a full breakdown of the assumptions used in our calculations, including the value of the car, CO2 emissions, fuel consumption, non-taxable items and more, you can send a Calculation Enquiry if there is something you don't understand or think might be incorrect. Alternatively, you can click to calculate tax on another car model instead.
