Belgium: Law project to introduce a new e-invoicing mandate from January 2026

Belgian parliament expected to approve the law project proposed by the government in the coming months.

Belgian parliament expected to approve the law project

The Belgian government on 28 December 2023 proposed a new law requiring the use of e-invoices in business-to-business (B2B) transactions starting 1 January 2026 and modifying the value added tax (VAT) code to match. This proposal defines an electronic invoice as one issued in a government-approved structured format.

The government recommends using the PEPPOL-BIS format for these invoices and distributing them through the PEPPOL network. Invoices in PDF and other digital formats will no longer qualify as structured electronic invoices. The proposed invoicing system would apply to all taxpayers established in Belgium invoicing transactions taking place in Belgium to recipients VAT-registered in Belgium.

Exceptions may apply for those under simplified tax regimes, those in bankruptcy proceedings, and those making only exempt transactions without VAT recovery right. To ease the transition, the government plans to offer additional deductions to help businesses cover the costs of necessary e-invoice tools. The project is expected to be approved in the coming months.
