This calculator helps you to calculate the income tax benefit in kind charge on a company car that an employer provides for an employee. This charge is mainly based on the type of fuel the car uses and the level of CO₂ emissions for the car in grams per kilometre and its list price up to £80,000.

For example, you enter the list price of the car of £16,500. The employee made no contributions or private use payments, so those should be left blank. The car was first registered in 2006, so enter 2006 or later. Enter Petrol or Euro IV compliant because it is a petrol car. If the employer does not pay for the employee’s private fuel, check the ‘No’ button on the ‘Employer pays for private fuel?’ The answer will be a benefit charge of £4,455 on which tax will be payable at either 22% or 40% and the percentage of list price used will be 27%.
