Invoice Format

EN16931 (Peppol BIS 3.0)

Belgium introduced mandatory structured B2B e-invoicing from 1 January 2026 for transactions between VAT-registered businesses established in Belgium. This requirement builds on existing B2G e-invoicing rules in public procurement and forms part of Belgium’s broader move toward the digitalisation of VAT processes. Under the mandate, businesses must issue and receive structured electronic invoices, typically exchanged via the Peppol network and compliant with the European standard EN 16931. The reform aligns with wider EU developments, including the VAT in the Digital Age (ViDA) initiative, which aims to support the harmonisation of digital VAT reporting across Member States. The introduction of structured e-invoicing is intended to improve efficiency through automation, reduce errors linked to manual processing, and support more effective VAT control and fraud prevention.
