This move is part of the government's broader initiative to embrace the benefits of electronic invoicing and streamline administrative processes.
The country has already undertaken the necessary steps to request a derogation from the European Commission, in order to be allowed to deviate from the provisions in the VAT directive 2006/112/EC and introduce mandatory electronic invoicing (e-invoicing) for domestic taxpayers.
Scope of the obligation
Starting from the 1st of January 2026, VAT-liable companies with a VAT registration and establishment in Belgium are obligated to receive and send structured electronic invoices, leaving no room to refuse them.
Even if a business is not required to issue invoices under national regulations, it must take the necessary measures to process and settle electronic invoices. The obligation refers to domestic B2B transactions, issued under the Belgium VAT law. Cross-border transactions are out of scope.
In the light of the obligation the government also amends the definition of electronic invoices. The new definition emphasises structured electronic invoices, distinguishing them from simple PDFs sent via email. The focus is on automatic and electronic processing, aligning with the concept of "machine-to-machine" communication.
Electronic invoicing framework
To facilitate this transition, the government has introduced the use of the Peppol network. Connecting via Peppol offers interoperability advantages, eliminating the need for bilateral agreements between participants and providing a common standard for all. The network is already operating in the country as a primary delivery method in the Business-to-Government (B2G) e-invoicing obligations.
In order to meet even the most specific needs of the businesses the government has created the so-called “Dual-Track” approach, where the first track - default network and format, will be based on Peppol.
The second “track” will allow taxpayers to opt-out from the default network, based on mutual agreement, and use another means for e-invoicing, i.e. EDI.
Government incentives and available tax deductions
Belgium's government understands the challenges posed by the mandatory transition. To incentivise businesses, the government has introduced a tax initiative which will allow businesses to claim tax on particular e-invoicing implementations, subscriptions and consultancy costs.
