Belgian car tax calculators 2026

The benefit in kind is the flat amount added to your taxable pay when you have a company car. It depends on the list price, the CO2 emissions and the age of the vehicle: enter these three figures.

A benefit in kind is not a deduction from pay: it is a taxable base. What you really pay is the benefit in kind multiplied by your marginal rate. Conversely, a self-employed person who deducts their car expenses saves the corresponding tax.

Director at 50%, BMW X1 sDrive18i (€41,000, 143 g)€2,249/year

When a company provides a car, part of the benefit in kind is added back to its taxable profit: 17%, or 40% if it also covers the fuel. The calculator quantifies the disallowed expense and the corresponding corporate income tax.

Every company car provided to an employee costs the employer a monthly contribution to the NSSO, which depends on CO2 emissions and, since 2023, on a multiplier that climbs every year. Enter the CO2 figure and the order date.

Since the 2021 reform, deductibility depends first on the order date: CO2 table before July 2023, gradual phase-out afterwards, 0% for a combustion car ordered from 2026. Electric cars stay at 100% up to orders placed in 2026.

On a car, VAT is never 100% recoverable: the VAT Code caps it at 50%, and only if VAT was actually invoiced. The calculator applies the exact rule to your price.

A PHEV whose emissions exceed the legal threshold loses its tax advantages: its CO2 is multiplied by 2.5 for the benefit in kind and it is deducted like a combustion car. Enter the WLTP figures and the calculator decides.

Three regions, three formulas. Enter the car’s characteristics: the calculator gives the registration tax of your region and compares it with the other two, for a new vehicle as for a used one.

New Golf 1.5 TSI (8 fiscal hp, 96 kW, 125 g) in Brussels€634.89

In Brussels and Wallonia, road tax depends on your fiscal horsepower. Electric cars pay the minimum, except in Flanders where the exemption ended for registrations from 2026.

Fiscal horsepower is not DIN horsepower: it depends on displacement and sets the road tax and part of the registration tax. Enter the displacement, the result is immediate.

Energy is often the second-largest item after depreciation. Real consumption, kilometres per year, price per litre or per kWh and share of home charging: the calculator projects the cost over your holding period, inflation included.

A loan costs its interest; a lease costs the gap between the rentals and the value financed. The calculator limits both to your actual holding period, as the TCO engine does.

Depreciation is the largest cost item of a car. AutoCalcul’s used-car valuation engine starts from an age curve calibrated on the Belgian market, then adjusts it for mileage, powertrain, body type, brand and condition.
