Mandatory electronic invoicing in Belgium from 2026: what you need to know

B2B electronic invoicing becomes mandatory in Belgium

From January 1, 2026, all VAT-registered businesses in Belgium will be required to send and receive their invoices in a structured electronic format via the PEPPOL network. This obligation covers B2B (business-to-business) transactions and follows the already existing requirement for B2G (business-to-government) transactions.

What is PEPPOL?

PEPPOL (Pan-European Public Procurement OnLine) is a standardized European network for exchanging electronic business documents. It ensures that invoices are transmitted securely, in a standardized and compliant manner.

Unlike a simple PDF sent by email, a PEPPOL invoice is a structured document (UBL format) that can be automatically processed by accounting software. This means:

• Fewer errors from manual data entry
• Faster processing of invoices
• Automatic and compliant archiving
• Interoperability with all business partners across Europe

Who is affected?

All VAT-registered businesses in Belgium are affected, regardless of their size:

• Self-employed professionals
• SMEs
• Large corporations
• Liberal professions

The only exceptions are flat-rate schemes and small businesses exempt from VAT.
