Belgium’s 4-Corner eInvoicing Model: What Businesses Need to Know for 2026 Compliance

  • From January 1, 2026, B2B eInvoicing is mandatory in Belgium for businesses established and VAT registered there.
  • Belgium uses a decentralized 4-corner model via certified Peppol Access Points (PAPs), not a government clearance platform.
  • The model involves the supplier’s system, supplier’s PAP, customer’s PAP, and customer’s system, ensuring secure and compliant invoice exchange.
  • Businesses must ensure their ERP systems connect to PAPs and comply with Peppol BIS 3.0, requiring coordination between tax, finance, and IT teams.
  • The 4-corner model will also support future eReporting obligations, so early preparation is advised.
