Getting ready for the Belgian B2B mandate?

The Belgian Federal Public Service Finance has you covered for all your questions

The Belgian Federal Public Service Finance has published some initial guidance in anticipation of the B2B e-invoicing mandate, which will take effect on January 1, 2026.

The newly released guidance, presented as an FAQ, answers critical questions about the upcoming e-invoicing mandate in Belgium. It covers the definition of a structured electronic invoice, required formats, processes for sending and receiving these invoices, and information on excluded transactions. The guidance is available in Dutch and French and aims to help businesses prepare for the new requirements.

These questions range from the basics (‘What is an electronic invoice?’) to more technical questions (‘What is the ‘authenticity of the origin’ of the invoice?’).
