Business woman with her new company car will now have to pay benefit in kind company car tax

Company cars are taxed as a benefit in kind

IF YOUR business provides your employees or directors with a car for business and private use, it is taxed – provided the employee or director earns £8500 or more per year.

This is known as company car tax.

Private use includes commuting – and the car merely has to “be available to you” for private use.

Company car tax is sometimes called benefit-in-kind tax (BiK in shorthand).

The taxman believes you are getting an additional benefit outside of work from work-supplied equipment, so he taxes you on it.

The amount of company car tax you pay is broadly determined by:

  • The list price of the car and any accessories fitted to it.
  • The car’s carbon dioxide (CO2) emissions.
  • The type of fuel the car uses.
  • The highest rate of income tax you pay (20% or 40%).

Generally, the higher the CO2, or list price, or your income tax, the higher your company car tax bill will be.

So a low-emission cheaper car will be more tax-efficient than an expensive and less economical model.

In broad terms the CO2 emissions and list price (P11D) determine the benefit in kind charge. This amount is added to your earnings as a cash value and then taxed as part of your overall income. Depending on your level of income, some of this will be taxed at 20%, and some at the higher 40% rate.
