Belgium E-Invoicing Compliance Overview
As of January 1, 2026, Belgium requires all VAT-registered businesses (except micro-enterprises) to issue and receive structured electronic invoices in B2B transactions; B2G e-invoicing has been mandatory for years. To comply, companies must adopt the EN 16931 invoice data model and exchange documents over the Peppol network, while also meeting archiving rules to ensure long-term integrity and accessibility.
