What does a company car
really cost you in 2026?
Autofiscaliteit works out the full tax bill of a company car: deductibility, benefit in kind, disallowed expenses and the CO₂ contribution to social security. For one car or for your whole fleet.
Enter a car or pick one from the catalogue of 163 models. You immediately see what it costs per year, how that develops up to 2031, and how it stacks up against the alternatives.
Free, and calculating works without an account. Registering is only for saving.
What you can do with Autofiscaliteit
Six parts, from a quick calculation for a single car to managing an entire fleet. Start wherever you like.
Work out one car
Pick a model, adjust the costs and see the deduction percentage, the benefit in kind, the disallowed expenses and the total annual cost straight away. No account needed.
Go to the simulatorCatalogue of 163 models
Electric, hybrid and combustion, with consumption, range, boot volume and towing capacity. Filter by make, body style or drivetrain and see the tax consequences per model.
Browse the catalogueCandidates side by side
Seven weighted criteria, from four-year cost to practical usefulness, with a chart and a verdict of accept, consider or reject. Every decision is kept.
Compare candidatesTrack your fleet
See per car when the deduction drops and what that costs, with a replacement calendar towards 2028. Necessary, because a car that is still deductible today will not be in two years.

Every parameter is open: reference CO₂, minimum benefit in kind, social security index, regional rates and charging rates. Each figure carries its legal source and how firm it is.
View the parametersWhat exactly gets calculated
The tax cost of a car is not one number but a stack of levies that each follow their own rules. This is what the calculation engine works through.
- Deductibility in corporate tax
- The gram formula, the phase-out calendar and the taper for electric cars, all hanging on the date of your order form.
- Benefit in kind
- List price, age and CO₂ percentage, with the statutory minimum and the employee's own contribution built in.
- Disallowed expenses
- The non-deductible share of the costs plus 17% or 40% of the benefit, depending on whether you provide a fuel or charge card.
- CO₂ solidarity contribution
- The monthly employer contribution to the NSSO. Your order date decides whether the multiplier applies, the contribution year decides how heavily it weighs.
- VAT deduction
- The 35% flat rate or actual business use, always capped at the statutory half.
- Registration and road tax
- The regional levies for Flanders, Wallonia and Brussels, flagging where a scale has never been officially published.
- Charge point and home charging
- The cost deduction on a charge point, the investment deduction and the amount you may reimburse tax free under the CREG rate.
- The fake hybrid test
- Too little battery per hundred kilograms or too many emissions, and your plug-in hybrid is taxed like a combustion car.
Why your order date now decides everything
Deductibility does not depend on when you drive but on when you sign. The percentage tied to your order period stays with the car for its whole life, so a signature one month late costs you years. Below, per order period, what electric and combustion each yield.

What counts is the date on the order form or lease contract, not the day the car is delivered. Keep that document: it is the only proof of your regime.

Frequently asked questions
Is this really free?
Yes. Every part is free, with no trial period and no limit on the number of cars. There is a page where you can contribute voluntarily, but nothing sits behind a paywall.
Do I need an account?
Not to calculate. The simulator and the catalogue work right away. A free account is only needed to save cars, put candidates side by side and track your fleet.
Where do the figures come from?
The tax parameters come from the Belgian official gazette and the circulars of the federal finance service, and are open on the parameters page with the legal source for each figure. Where a figure comes from a secondary source or is not yet final, that is stated explicitly.
Can I base my decision on this?
As a starting point yes, as an end point no. The calculation is informative and not tax advice. For a concrete file your bookkeeper or a certified accountant should still look at it, certainly with light commercial vehicles, foreign plates or split financial years.
What happens to my data?
Your cars and decisions are strictly walled off per company, enforced in the database itself and not just in the web page. Anyone calculating without an account leaves nothing behind at all: that calculation happens in your browser.
