Belgium Mandates Structured Electronic Invoicing for B2B Transactions Starting January 2026

• From January 1, 2026, Belgium mandates electronic invoicing for all B2B transactions between Belgian VAT-liable entities.
• The Royal Decree of July 14, 2025, confirms this obligation and defines technical requirements.
• Peppol BIS is the default standard for electronic invoices, but other formats are allowed if they meet European standards.
• The obligation applies if the supplier and recipient are VAT-registered businesses in Belgium and the transaction occurs in Belgium.
• Invoices to private consumers can still be issued on paper or in other formats.
• New administrative fines for non-compliance are introduced: 1500 euros for a first offence, 3000 euros for a second, and 5000 euros for subsequent offences.
• Existing penalties for incomplete or incorrect invoices apply to e-invoices.
• There is a risk of VAT deduction denial if invoices are not in the proper electronic format.
• New VAT rounding rules for electronic invoices start in January 2026, allowing rounding only on the total VAT amount.
• Companies need to adapt invoicing systems and accounting processes to comply.
