Since January 2017, it is compulsory to send e-invoices to the Flemish Regional Government!
The Belgian Federal Government actively receives e-invoices. Increasingly more government bodies will incorporate compulsory digital invoicing into their tenders. E-invoicing will become compulsory in November 2018, at the latest (november 2019 for certain types of receivers).
The other regional governments in Belgium will also be in a position to receive e-invoices in the near future.
The first town/city authorities and municipalities will be in a position to receive e-invoices as of 2017 and the system will become compulsory across the board as of November 2019.
