You’ll pay tax if a company car is given to you or your family to use privately, including for commuting.
You pay tax on the value of the company car, which depends on things like how much it would cost to buy and the type of fuel it uses. Its value is reduced if you have the car part-time or you pay something towards its cost.
If your employer pays for fuel you use personally and not for your job, you’ll pay tax on this separately.
