Brussels, 30 June 2026 – Belgium’s B2B e-invoicing mandate has been live for six months, but the next phase is already confirmed: from 1 January 2028, Belgian businesses will be required to report invoice data to the tax authority in near real time. This Belgium e-reporting 2028 Peppol obligation operates through a 5-corner Peppol model, in which the Belgian tax authority (FOD Financiën / FPS Finance) becomes the fifth corner of the network. The framework is aligned with the EU’s ViDA Digital Reporting Requirements and positions Belgium as an early adopter of continuous transaction controls at national level.
What is near real-time e-reporting?
Near real-time e-reporting means that invoice data is automatically transmitted to the tax authority at or near the moment of invoicing. Businesses do not need to file a separate report: data flows through the Peppol network as invoices are sent and received.
This replaces the current system of periodic customer listings submitted to FPS Finance. From January 2028, those periodic filings will be replaced by a continuous data stream via Peppol.
What is the 5-corner model?
Belgium’s current e-invoicing mandate uses the standard 4-corner Peppol model: sender (corner 1) → sender’s Peppol Service Provider (corner 2) → receiver’s Peppol Service Provider (corner 3) → receiver (corner 4). The 5-corner model adds a fifth participant: the Belgian tax authority. Invoice data is simultaneously forwarded to the tax administration as invoices flow through the network.
This architecture — also referred to as Continuous Transaction Controls (CTC) — closely mirrors the design the EU is considering under ViDA for cross-border B2B transactions from 1 July 2030. Belgium is implementing the model domestically ahead of the EU-wide harmonisation deadline.
What does this mean for your business?
For businesses already connected to the Belgian Peppol network via a certified Peppol Service Provider, the 2028 transition will in most cases be a technical update handled by the Service Provider. However, two actions are worth taking now.
Ask your Peppol Service Provider about 2028 readiness. Confirm that your Service Provider has a roadmap for the 5-corner transition before January 2028. Reliable providers communicate this proactively. If you do not yet have a Peppol Service Provider for the Belgian market, use our comparison tool to identify suitable options.
Verify your invoice data quality. Near real-time reporting leaves no margin for incomplete or inaccurate invoice fields: discrepancies become immediately visible to the tax authority. Check that your ERP or accounting software outputs all required fields correctly and completely.
Non-established businesses with Belgian customers. The 2028 e-reporting obligation applies to Belgian-established suppliers. Non-established VAT-registered businesses are not in scope for the reporting requirement, but must still be able to receive e-invoices from Belgian customers. Monitor developments closely as ViDA may extend reporting requirements to non-established businesses in subsequent phases.
Connection to ViDA
Belgium’s 5-corner model is architecturally aligned with the EU’s Digital Reporting Requirements (DRR) under ViDA, which mandates real-time reporting for intra-EU B2B transactions from 1 July 2030. Belgium goes a step further by also applying the model to domestic B2B transactions from 2028, making it one of the first EU member states to implement a ViDA-compatible continuous reporting model at national level.
