Benefit in kind – Private use of a company car: updated formula for 2023


The Royal Decree implementing the new reference CO2 emission for calculating the taxable benefit in kind for the private use of a company car in the hands of company directors and employees has been published in the Official Gazette on 16 December 2022.

For income year 2023, the following CO2 emission will be applied to the above taxable benefit in kind:

  • Petrol, LPG or natural gas cars: 82 g CO2/km (instead of 91 g CO2/km for income year 2022)
  • Diesel cars: 67 g CO2/km (instead of 75 g CO2/km for income year 2022)

Just as last year, the decrease of the reference CO2-emission is substantial. The increasing popularity of hybrid and electric cars results in a lower average emission of all cars driving in Belgium. Please be aware that, the lower the CO2-reference, the higher your taxable benefit in kind will be for CO2 emission cars.

Please note that the minimum taxable benefit in kind for a company car (i.e. EUR 1.400 for income year 2022) has not yet been communicated for income year 2023. There are no further changes to the lump-sum valuation method for the benefit in kind.

The above reference CO2 emission is effective as of 1 January 2023 and the corresponding benefit in kind should already be processed in the January payrolls.
