E-invoicing in Belgium: End of the grace period and full enforcement of the mandate now in effect

As of the second quarter of 2026, Belgium has ended the general tolerance period for mandatory e-invoicing, requiring all VAT-registered businesses, including those under the small business VAT exemption, to fully comply with exchanging structured electronic invoices.
The obligation extends even to businesses that only invoice private individuals but receive invoices from Belgian suppliers, mandating their ability to handle electronic invoices.
Limited exceptions remain until June 30, 2026, for self-billing functionality not yet implemented by software providers, and on a case-by-case basis for exceptional and demonstrable technical issues, requiring individual review by tax authorities.

Effective April 1, 2026, Belgium’s B2B e-invoicing grace period ended, making full compliance mandatory for all VAT-registered businesses, with the exception of self-billing invoices which receive an extended tolerance until June 30, 2026.
Non-compliance with the e-invoicing mandate carries significant financial penalties up to €5,000, in addition to existing invoicing rule penalties and potential commercial and cash flow issues due to invalid or undelivered invoices.
Businesses must ensure their systems are fully configured for issuing and receiving B2B invoices in PEPPOL BIS format via the PEPPOL network, with thorough validation of scope, e-invoice accuracy, VAT treatment, and reporting crucial for compliance and future readiness.
