The company car and its BIK
Using a company car privately constitutes a benefit in kind (BIK), added every year to your taxable income. Its amount depends on the catalogue value, CO₂ emissions and the vehicle’s age. That is why an electric car, at the minimum CO₂ coefficient, shows the lowest BIK, a major tax lever.
Private leasing
On the private side, leasing (or long-term rental) lets you drive a recent car for an all-inclusive monthly fee (maintenance, insurance, road tax). The advantage is budget predictability; the drawback is that you own nothing at the end of the contract and the total cost often exceeds buying. And, unlike a company, a private individual cannot deduct anything.
Which trade-off?
Company or private, the right decision always comes down to the real cost: taxable BIK on one side, total leasing cost on the other. Estimate both before choosing.
Frequently asked questions
How is the company car benefit in kind calculated?
BIK = catalogue value × CO₂ coefficient × 6/7 × age coefficient, with a legal minimum (€1,690 for 2026). The CO₂ coefficient starts at 5.5% at the reference emission and ranges from 4% to 18%. The BIK calculator does the full computation.
Why does an electric car have the lowest BIK?
An electric car (0 g CO₂) benefits from the minimum 4% coefficient, which strongly reduces the taxable benefit compared with an equivalent combustion car.
Is leasing worthwhile for a private individual?
It offers a fixed, all-inclusive monthly budget, but you own nothing at the end and the total cost often exceeds buying. Unlike a company, a private individual cannot deduct lease payments. The leasing calculator estimates the total cost.
Company car or private car?
A company car is taxed via the BIK (and deductible for the employer); a privately leased car offers no deduction to an individual. The right choice depends on your status and mileage.
