As from July 1st, 2026, a surcharge for CO₂ emissions will be applied to the rates of the kilometer charge in Flanders. To determine the CO₂ emission class of a vehicle, use our CO₂ emission class calculator
Since 1 January 2026, electronic invoicing is mandatory in Belgium.
This implementation means that when a vehicle subject to the kilometer charge drives in Wallonia, an electronic invoice will be sent in the name of SOFICO, without this implying any direct payment on your part.
This change concerns only the format of the invoice and does not modify the payment procedures for the kilometer charge.
For Flanders and the Brussels-Capital Region, no change occurs: the documents and payment procedures remain identical to those applied until 2025.
In practice, there is therefore no double invoicing. The payment procedures for the kilometer charge thus remain strictly unchanged for the user.
