The draft law on B2B e-invoicing in Belgium was published on 28 December 2023, approved by the Chamber of Representatives in February 2024 and published in the Official Gazette after the King's signature.
The proposed law will become mandatory for all companies, both issuing and receiving electronic invoices, starting from 1 January 2026.
How will the implementation of B2B e-invoicing take place in Belgium?
No definite timetable has yet been set for implementing B2B eInvoicing in Belgium. What is known is that it will start in January 2026 and that the implementation will be gradual, in accordance with the turnover of the taxpayers.
- Large taxpayers with a turnover exceeding €9 million.
- Medium-sized taxpayers with a turnover ranging from €7 million to €9 million.
- Small taxpayers with a turnover of less than €7 million.
B2G e-invoicing: Background and Current situation
E-invoicing in Belgium has undergone significant developments in recent years, driven by the European Directive 2014/55/EU.
The Flemish region led the implementation in 2016 by adopting e-invoicing in all its public institutions, marking the beginning of a country-wide transition process.
In 2018, this obligation was extended to the federal level for contracts above €135,000, becoming mandatory for all federal authorities in 2019.
Implementation process of B2G e-inovicing in Belgium
In 2020, e-invoicing was gradually implemented in all Belgian federal government entities. On 9 March 2022, e-invoicing became mandatory in Belgium for all public sector entities and their associated bodies, both federal and regional.
Starting from 1 November 2022, companies participating in public contracts outside the European Union are required to use electronic invoicing within six months of the regulation's publication.
Belgian companies involved in public contracts above 30,000 euros will have to adopt e-invoicing within 12 months of the publication of the regulation, with effect from 1 May 2023.
The third phase, originally scheduled for November 2023, has been postponed to March 2024 and will cover the remaining public contracts (below €30,000). It should be noted that contracts under €3,000 may be exempt from this obligation, depending on the policies of each government agency.
How to exchange e-invoices in Belgium?
In order to send electronic invoices to public administrations, taxpayers can use the centralised Mercurius platform, which is connected to the PEPPOL network. The mandatory format is PEPPOL BIS and electronic signatures are not required.
In Belgium, B2B e-invoicing will follow the same model as in the B2G area, aiming for a 5-corner PEPPOL model that includes near real-time electronic reporting, replacing the annual customer list report.
Connection via PEPPOL ensures interoperability, eliminating the need for individual agreements between participants and establishing a common standard for all users.
