Understanding the Belgian Mandate

Belgium is transitioning to a mandatory structured e-invoicing model for all business-to-business (B2B) transactions. This mandate is a significant shift from traditional invoicing (paper or PDF) and requires a new approach to compliance.

• Mandatory Deadline: From January 1, 2026, all VAT-registered businesses in Belgium must be able to issue and receive structured electronic invoices for their B2B transactions.

• What is a "Structured E-Invoice"? A structured e-invoice is not a PDF file. It is a machine-readable data file, specifically an XML file, that must conform to the European Standard EN 16931 and the Peppol BIS 3.0 format. From the 2026 deadline, unstructured formats like paper invoices or PDFs sent via email will no longer be considered legally compliant for B2B transactions.
