Working out your company car tax in the UK
There’s no need for a desk calculator or complicated percentage charts. Our easy-to-use company car tax calculator above helps you estimate how much tax is due on any car, covering the 2026/27, 2027/28 and 2028/29 tax years.
The company car tax calculator shows the tax payable at the 20% and 40% income tax rates. You can also explore the effect of the company car on take-home pay by entering a salary in the section marked ‘Earnings’. The calculator estimates the net salary after taking account of benefit-in-kind (BIK) tax.The calculator can also show the additional fuel benefit tax that may apply if your employer pays for fuel used on private journeys.

Considering an EV through salary sacrifice?
If you are considering an electric car through a salary sacrifice scheme, you can use this calculator to estimate the company car tax element. Your full monthly cost also depends on the salary you give up, the effect on Income Tax and National Insurance, and what your scheme includes. Your salary sacrifice quotation will show the estimated effect on your take-home pay.
The calculator also provides information about your chosen car, including its official fuel economy or electric range, acceleration and NCAP safety rating, where available. So, it’s more than just a company car tax calculator – it helps you compare your options and choose the right company car.
