Characteristics of the electronic invoice in Belgium

The use of electronic invoices in Belgium was adopted in 2013, at which time the government declared e-Invoices had the same validity as paper invoices.

In the public sector, it is mandatory for all federal and central administrations to receive e-Invoices. This obligation applies to suppliers of such public entities in several regions (Brussels, Flanders, Wallonia). Now, the obligation to issue e-Invoices has been extended to all suppliers of public administrations. 

The Belgian Finance Minister has unveiled a series of measures for a tax reform in the country, including the mandatory use of B2B electronic invoicing and electronic VAT reporting.

Common questions

Electronic invoices issued to the public sector can be sent following the PEPPOL model. The federal government has a central reception platform called MERCURIUS connected to the PEPPOL network. All the public entities in the country -centralized and decentralized- can us this platform. However, they may also choose to have a direct connection with PEPPOL.

Currently, it is only mandatory for all public administrations and their suppliers in Flanders and Brussels.
