Belgium’s government confirmed on its official e-invoicing page on 19 March 2024 that non-established VAT-registered entities in Belgium are excluded from the e-invoicing mandate. However, the legislation has yet to be amended to include this decision.

Starting 1 January 2026, all Belgian companies subject to VAT will be required to use structured electronic invoices for transactions with one another. These invoices are seamlessly exchanged directly between the software systems of both businesses.

Earlier, the Belgian parliament passed the Law of 6 February 2024 on 20 February 2024, which made electronic invoicing mandatory for domestic business-to-business (B2B) transactions from 1 January 2026. Only taxpayers involved in VAT-exempt transactions, bankrupt taxpayers, and foreign taxpayers registered for VAT in Belgium are exempt from this mandate.
