ELECTRONIC INVOICING
E-Invoicing
in Belgium
Format: Peppol

Where are we now?
In Belgium, e-invoicing is entering a new phase with the introduction of the mandatory B2B obligation from 1 January 2026. The adopted model is based on the PEPPOL network, which enables the direct exchange of structured electronic invoices between businesses, without routing through a centralised platform. All VAT-registered businesses must therefore be able to issue and receive invoices in a format compliant with the European standard EN 16931 (typically PEPPOL BIS 3.0 in XML).
Unlike other countries, Belgium has chosen a decentralised approach, in which the PEPPOL infrastructure is the primary channel for ensuring interoperability and process automation. PDF or paper invoices are no longer considered valid for domestic B2B transactions, marking a significant shift in administrative processes and company ERP systems. In the public sector (B2G), the obligation has already been in force for several years, based on the Mercurius platform integrated with PEPPOL. Looking ahead, Belgium plans to introduce e-reporting by 2028, with the aim of involving the tax administration directly in the data flow through the five-corner model, in line with European initiatives such as ViDA.
For businesses, adapting to the Belgian model means not only complying with a legal obligation, but also evolving towards more efficient, interoperable digital processes — ready for the future of tax compliance across Europe.
