If there is a third certainty in life, it is surely that all matters relating to taxation will be horribly complicated.
Company car tax is no exception, and when changes are made to the system on a seemingly annual basis and the tax bands themselves are fiddled with just as often, the complexity of it all spirals out of control.
However, the reason why Her Majesty’s Revenue and Customs (HMRC) charges tax on the car your employer makes available to you is at least easy enough to understand. A company car is a benefit second only to the salary you are paid and HMRC therefore sees it as a taxable one. It calls it a ‘benefit in kind’, a term applied to any taxable perk or incentive other than your basic salary.
So if you run a company car, you will have to pay a certain amount of tax. A company car is defined as one that is made available to you by your employer and that you are allowed to use personally outside of working hours, as well as for work. HMRC considers your commute to and from work to be personal use.
Calculating the amount of tax you’ll be liable to pay appears daunting at first, but it is actually reasonably straightforward. We’ll take a closer look at that later on. But put simply, the calculation is based upon the value of the car, your salary, the car’s CO2 emissions and the type of fuel it runs on. CO2 is the primary factor here because the government wants to incentivise us all to drive cleaner cars. Therefore, the lower the car’s CO2 emissions, the less tax you pay, all other things being equal.
In recent years, there have been significant changes to the way company car tax is structured. Diesel cars are subject to a 4% surcharge because they emit more nitrogen oxide, which is harmful on a local level. This was increased from 3% in April this year as part of the government’s efforts to discourage us from driving diesels. Meanwhile, electric and hydrogen fuel cell cars are no longer exempt from company car tax, although they do sit in a much lower tax band.
