e-lnvoicing in Belgium is a national e-invoicing system based on the Peppol framework, enabling e-invoice exchange between sellers and buyers in the standardized Peppol BIS format. Currently, B2B Belgium e-invoicing follows a 4-corner model wherein the supplier transmits invoice data to buyers via an Access Point, without the government being involved in the data transmission. The government gets updated only during periodic VAT return filing.
However, as the country transitions towards mandatory near real-time VAT e-Reporting from Jan 1, 2028, both sellers and buyers will be required to submit e-invoice data to the Belgian tax authority, FPS Finance, turning the 4-corner into a 5-corner model. In contrast, B2G e-invoices in Belgium already route through the central Mercurius portal before reaching the public sector buyer.
Belgium e-invoicing requires VAT-registered businesses to exchange e-invoices through the Peppol network, with VAT e-Reporting planned for 2028.
| Requirement | What it involves |
|---|---|
| Applicable Transactions | B2B and B2G transactions. Excludes B2C, intra-EU supplies and VAT-exempt transactions. |
| Applicable Documents | Sales invoices, credit notes, and debit notes |
| Invoice Format | Peppol BIS Billing 3.0 (EN 16931) |
| Receiving Invoices | In-scope B2B businesses must be able to receive Peppol e-invoices |
| VAT e-Reporting | Near real-time reporting by supplier and buyer. Planned from 1 January 2028. |
| B2G Invoicing | Invoices exchanged via Peppol and routed through the Mercurius platform |
