When a car is provided by an employer to an employee or director and the beneficiary also uses the car for private purposes a taxable benefit in kind (BIK) is generated. This benefit in kind is subject to withholding taxes. The taxable value of the benefit is added to the taxable remuneration, the total is subject to withholding taxes. Benefits in kind are normally taxed on their market value. With regard to company provided cars the value is determined on a lump sum basis.
As of January 1, 2012 the taxable benefit is determined based on the catalogue value and the CO2 emission of the car. As of May 1, 2012 the benefit is amortized based on the age of the car. Per year the taxable benefit is reduced with 6% (with a maximum reduction of 30%, i.e. as of 5 years). The catalogue value is the actual value of the new car including the price of the options and the actually paid VAT. Discounts are not to be taken into account. However, promotional discounts which are published and applicable to everyone can be taken into account. As of January 1, 2017 the disallowed expense amounts to 40% instead of 17% in case the employer intervenes in the fuel costs and/or provides a fuel card.
For cars whose NEDC emissions are known, the NEDC value is taken into account; for cars whose emissions are known but not NEDC, the WLTP value is taken into account; and for electric cars, the 0 emissions are taken into account.
For hybrid cars with a battery capacity of less than 0.6 kWh per 100 kilograms of car weight purchased after 1 January 2018, the benefit will be calculated from 2020 on the CO2 emissions of the corresponding petrol or diesel model.
For purely electric cars, the benefit is always calculated at 4% of the catalogue value.
BIK = catalogue value x age ratio x (5,5 + (0,1 x (CO2-emission - reference emission))) x 6/7 [1]
