Electric company cars: 5× more tax-efficient!

In Flanders, “very favourable” is an understatement: until the end of the year, fully electric vehicles are completely exempt. That means €0 registration tax and €0 annual road tax. For cars with high engine power, this easily translates into hundreds or even thousands of euros saved. 

Brussels and Wallonia have been slightly less generous, applying the minimum rate for both taxes. Since 1 July 2025, a new registration tax calculation has been introduced, also affecting electric vehicles. From now on, factors such as CO₂ emissions, technology and weight play a role. The first two do not apply to EVs, or even work in their favour — but weight becomes a crucial factor, especially if you're planning to order a heavy electric SUV …

The calculation is complex, so we’ll spare you the details. Want to know how much road tax you’ll pay for your (electric) car? You can run a simulation here. 

New rules in Flanders as of 1 January 2026? 

Flanders plans to abolish tax exemptions for electric cars, although rates will likely remain lower than for comparable fuel cars. Vehicles registered before that date would keep their exemptions. The exact legislation is still unclear, and organisations like EV Belgium have already expressed strong opposition. So… to be continued! 

The solidarity contribution is a fixed social contribution paid by the employer based on the vehicle’s CO₂ emissions. For petrol and diesel vehicles, it was significantly increased in 2023. Electric vehicles are emission-free, so employers pay the legal minimum — resulting in substantial monthly savings and a significantly lower TCO (Total Cost of Ownership) for your fleet. 

To stimulate electric company cars, charging stations on company premises were 150% deductible until 31 August 2024. That period is over, but a 100% tax deduction remains highly attractive. Even better: charging stations installed at employees’ homes can also be treated as a deductible business expense. 

All electricity used to charge company cars — at the office, at home or at public charging points — is tax-deductible as a professional expense. 
Reimbursing home charging sessions to employees can also be done in a tax-friendly way through the home charging allowance, based on official CREG tariffs. 

The BIK (Benefit in Kind) is the taxable benefit employees receive when they are allowed to use their company car privately. 
The calculation takes into account the catalogue value, the age of the vehicle and its CO₂ emissions. Since electric cars are emission-free, the minimum rate of 4% applies. 
For employees, this means a very low taxable amount, and therefore more net salary.

In other words: those who don’t switch are missing out. Instead of seeing electrification as a forced transition imposed by the government, you can also view it as a massive gift: more net salary for employees and significant tax benefits for companies — not to mention lower maintenance costs, (green) insurance premiums and other advantages. 

Are there any downsides? Not if you choose a complete charging solution from Q8. 
With our charging stations and charging card, you can charge your (company) car at home, at the office and on the road across Europe. Electric driving becomes a seamless experience and as a fleet manager, you have a single platform to manage invoicing and reimbursements. 

As we all know, Belgian tax rules can change almost as quickly as the weather. 
Between the moment we write this article and the moment you read it, some rules or rates may have changed again. So always check the official government websites for the most up-to-date information, or consult a specialist!
