Belgium: Mandatory e-Invoicing in 2026 and e-Reporting in 2028

Preparing Business Systems for Belgium’s Peppol-Based Mandate 

As of January 2026, Belgium requires companies registered for VAT in the country to issue and receive structured electronic invoices for their B2B transactions.

The transition is not just about the e-invoicing requirement. It also anticipates the next regulatory step: a near real-time e-reporting model, scheduled for 2028, which reinforces the role of Peppol, the EN 16931 formats, and the ability to exchange data with structure, traceability, and validation. That framework was already defined in greater detail when the mandatory use of B2B electronic invoicing in Belgium was confirmed, and now the focus is on how to implement it in daily operations.

This video goes beyond the regulation itself, breaking the topic down into concrete decisions regarding Peppol connectivity, format conversion, integration with systems such as SAP, Oracle, or Microsoft Dynamics, and the automation of tasks that often continue to cause friction when data is poor or processes rely on too much manual intervention. For groups with a presence in multiple countries, it also helps situate the Belgian case within a broader strategy for multinational compliance.
