Belgian e-invoicing in 2026: a practical Peppol checklist
Since 1 January 2026, structured e-invoices are required for covered domestic B2B transactions between Belgian VAT businesses. A PDF by e-mail alone is not the structured invoice.
Belgium introduced mandatory structured electronic invoicing for covered domestic transactions between businesses subject to Belgian VAT from 1 January 2026. A PDF attached to an e-mail is not a structured e-invoice. The system is designed for software to exchange and process invoice data, generally through the Peppol network.
Check whether your transactions are covered
- The main obligation concerns domestic B2B transactions between Belgian businesses subject to VAT. Check the current official guidance for the precise scope and exceptions that apply to your business.
- Invoices to private consumers are outside this B2B sending obligation, but a business may still need to receive structured invoices from its Belgian suppliers.
- Cross-border transactions follow separate rules; do not assume the domestic Belgian requirement applies in the same way to every foreign customer or supplier.
- The Belgian tax administration has clarified that small-business VAT-franchise status does not by itself remove a business from the obligation when the relevant domestic B2B invoicing conditions are met.
Get ready to send and receive through Peppol
- Ask your accounting or invoicing software provider whether the system can both send and receive structured invoices, not only create a readable PDF.
- Confirm that your software supports the required structured format and Peppol exchange. The recipient must be able to process the invoice data automatically.
- Check your company details and customer records, including VAT numbers and Peppol addressing, with your accountant or service provider.
- Agree internally who checks incoming invoices, handles errors and matches them to orders and payments.
What changes in your daily workflow
The structured invoice is the legally relevant electronic document for transactions covered by the Belgian rule. You may also send a PDF or print view for readability, but that copy does not replace the structured invoice. Keep the original structured data and make sure the invoice remains readable and unchanged throughout the retention period.
A simple readiness check
Before your next Belgian business invoice, confirm that your software is connected for Peppol, your customer is identified correctly, the invoice data is complete and the structured document has been accepted for delivery. Test the incoming side too: ask a Belgian supplier to send a structured invoice and make sure your team can find, review and record it.
