New CO2 contribution: what you need to know

For 2024, the Belgian government decided to reduce the CO2 solidarity contribution that employers pay for company cars. These changes are an effort to reduce CO2 emissions and encourage green mobility. In this article, we discuss the main changes this new scheme has.

For cars with internal combustion engines (diesel/gasoline) ordered after July 1, 2023, CO2 contribution rates have increased significantly. The contribution is calculated based on the vehicle's CO2 emissions. Until June 30, 2023, the standard rates applied, but from July 1, 2023, these rates are multiplied by an increase factor:

01.07.2023x 2,25
01.01.2025x 2,75
01.01.2026x 4,00
01.01.2027x 5,50

In addition, the minimum contribution will also increase:

From:Minimum contribution (before index):
01.07.2023€ 20,83 (€31,34 after index)
€ 23,41
€ 25,99
01.01.2027€ 28,57
01.01.2028€ 31,15

This means that cars with combustion engines will contribute significantly more to the CO2 contribution.

Impact on employers and company fleet

These changes will affect employers. They will bear higher costs for offering combustion-engine company cars because of increased CO2 contributions. In addition, the tax advantages for internal combustion engine cars is being phased out, further reducing the attractiveness of these vehicles for employers.

Plug-in hybrids and EVs pay minimum rate

But there is good news because for plug-in hybrids and electric cars, even those ordered after July 1, 2023, will remain at the indexed minimum of 31.99 euros in 2024. They will also enjoy an indexed minimum in the following years.

Buying an electric car also remains interesting for its many tax advantages such as the new bonus up to 5,000 euros for the purchase of an EV or the tax deductions for installation of a publicly accessible charging station. 

Consider an electric car

Choosing environmentally friendly vehicles such as full electric cars is now driven not only by ecological reasons, but also by financial incentives. EVs not only offer a more advantageous option under current regulations, but also contribute to a greener future.
