NederlandsE-invoicing in Belgium
Belgium now requires electronic invoicing for domestic B2B transactions. Since January 1, 2026, most businesses established in Belgium must issue and receive e-invoices instead of traditional paper or PDF invoices.
The reform is designed to help reduce the VAT gap, streamline invoicing processes, and modernize the way businesses securely exchange invoices.

Frequently asked questions
Is e-invoicing mandatory in Belgium?
Yes. Structured B2B e-invoicing has been mandatory for all domestic transactions between Belgian VAT-registered businesses since January 1, 2026. This follows the existing B2G mandate, which has been in place for several years.
What is e-invoicing in Belgium?
E-invoicing in Belgium refers to the use of structured electronic invoices that can be automatically processed by accounting or invoicing software. Unlike a PDF sent by email, a structured e-invoice contains invoice data in a standardized machine-readable format.
Since January 1, 2026, structured e-invoicing has been mandatory for domestic B2B transactions between Belgian VAT-registered businesses. In practice, invoices are generally exchanged via the Peppol network in Peppol BIS format, unless both parties agree to another channel that complies with the European standard EN 16931.
This B2B requirement builds on Belgium’s existing B2G e-invoicing obligations, where electronic invoicing is already required for many invoices sent to public authorities.
Is Peppol mandatory in Belgium?
Peppol is the default and highly recommended network for the Belgian mandate. Businesses may agree to use other channels, such as EDI, provided they meet European standards.
