Structured e-invoices are mandatory between businesses
VAT-registered businesses established in Belgium must exchange structured electronic invoices with each other, in practice through the Peppol network. A PDF sent by email is no longer a valid invoice between businesses. The three-month grace period ended in late March 2026. For SMEs and the self-employed, e-invoicing costs qualify for an increased deduction until 2027.
In practice, the invoice becomes a data file that moves from one software package to another through a certified provider, with no re-keying. Credit notes follow the same rule. Invoices to private individuals and foreign businesses are not covered by the obligation. The second stage, real-time reporting of invoice data to the tax authorities, is planned for 2028.
Applies to: Every VAT-registered business that invoices other businesses.
