From tax rules to market trends: everything you need to know about your company car, whether you're still driving it or saying goodbye.
A company car is a car provided by your employer, often including a fuel card, for both commuting and private use. For tax purposes, the government considers this a taxable benefit in kind. The exact cost for you in 2026 depends on CO2 emissions, catalogue value and fuel type.
For years, the company car has been a fixed part of the Belgian salary package. For many employees and self-employed professionals, it is an attractive way to combine mobility with tax optimisation. However, legislation is changing rapidly, and with full electrification by 2026, choosing a fossil-fuel company car is becoming increasingly expensive. That is why more and more drivers are considering selling their car and switching to an alternative, such as an electric model or the mobility budget.<br><br>Opkoper Bedrijfswagen helps you with this: request a <a href='#'>free valuation</a> and find out what your company car is worth today.
A company car is a vehicle purchased or leased by a company and made available to an employee or director. It may be used for professional journeys, but also privately; in Belgium, the distinction makes no difference for tax purposes. The term covers both passenger cars and light commercial vehicles registered in the company's name.
For self-employed professionals, the company car is often both a work tool and a status symbol. Executives tend to drive more luxurious models, while sales representatives focus mainly on economy and reliability. What all company cars have in common: they represent a significant value that you can cash in at any time through a targeted sale.
The benefit in kind is added to your gross salary monthly and taxed. For years, the formula was: catalogue value × CO₂ percentage × 6/7 × age coefficient. From 2026, the age factor disappears and only CO₂ emissions remain decisive. Concretely: a diesel car with 120 g CO₂/km and a catalogue value of €35,000 cost an average of €200 per month in extra taxes in 2025; in 2026 this could rise to €280.
For electric company cars, the benefit remains limited: only 4% of the catalogue value must be declared as an employee. Those who receive a private charging station from work pay no extra tax on that either. This makes choosing an electric company car increasingly attractive, while at the same time increasing the resale value of existing diesel and petrol cars on the second-hand market.
For companies, tax deductibility is crucial. Since 2020, a phase-out scheme applies: cars with high CO₂ emissions are becoming less and less deductible. Diesels and petrol cars newly purchased from 2026 are even 0% tax deductible, unless they are plug-in hybrids with low CO₂ emissions. Only fully electric company cars can still count on a full 100% deduction.
This is turning the second-hand company car market upside down. Many companies are already disposing of their polluting models and switching to emission-free alternatives. This shift is creating a growing supply of affordable, well-maintained company cars on the used car market. For self-employed professionals and SMEs that need one or two cars, this is a unique opportunity.
The popularity of the company car remains undiminished. According to data from the FPS Finance, there are almost 1.5 million salary cars on Belgian roads, together accounting for about 30% of the vehicle fleet. The average catalogue value of a new company car is around €38,000, but on the second-hand market you often pay half that for a three- to five-year-old model.
Demand for small company cars, such as the Volkswagen Polo or the Audi A1, is increasing. Self-employed professionals who only need a car for short trips are increasingly leaving larger models aside. At the same time, robust vans such as the Mercedes Vito or the Ford Transit remain indispensable for construction workers and installers. The market value of your car today therefore depends strongly on the type, age and mileage.
More and more entrepreneurs and employees are choosing to sell their company car for various reasons. Perhaps your business is closing, you are switching to a mobility budget, or you simply want to avoid your car losing further value as regulations tighten. Especially with the upcoming tax reform, it may be wise to part with a diesel or petrol car before 2026.
The best time to sell your company car is usually in early spring. In February, demand for used company cars peaks: many companies purchase their annual fleet then and buyers are willing to pay a bit more for a good example. Conversely, it usually doesn't pay to sell in October, when the market is traditionally calm.
