E-Invoicing / Europe / Belgium
E-Invoicing in Belgium
Structured B2B e-invoicing became mandatory January 1, 2026 for almost all transactions between Belgian-established VAT-taxable businesses. PDF invoices alone no longer satisfy the B2B requirement.
Regulatory status current as of September 2026. Requirements change frequently; confirm final obligations with the relevant tax authority and your legal/tax advisors.

Key data / ERP impacts
Businesses typically send and receive structured invoices through the Peppol network, typically using Peppol-connected invoicing or ERP software and a Peppol service provider.
Alternative arrangements may be used by mutual agreement where they comply with EN16931.
Data must strictly conform to the Peppol BIS Billing 3.0 schema or EN16931.
Peppol participant identifiers and buyer master data must be accurate so invoices can be correctly routed and processed.
How InTaxOps helps
InTaxOps helps you meet data conformity and mapping requirements so your Peppol or alternative connections work smoothly.
Common questions
Is there a central clearance portal in Belgium?
No — Belgium uses a decentralised model (often the 4-corner model via Peppol) rather than a central platform like Poland's KSeF.
Do we need Peppol connectivity?
Peppol is the default/reference network, but alternative arrangements may be used by mutual agreement where they comply with EN16931.
