Belgium to Implement Mandatory E-Invoicing for Domestic B2B Transactions in 2026

• Belgium will introduce mandatory e-invoicing for domestic B2B transactions in 2026.
• Businesses in Belgium will have to issue invoices electronically in a structured data format.
• The plan is to implement this obligation on January 1, 2026, after approval from the European Commission and Parliament.
• The e-invoicing mandate aims to reduce errors, costs, and fraud, and improve efficiency and transparency.
• The common European standard for e-invoicing, EN16931, will be used, but businesses can use another format as long as it follows the standard.
• Sending a PDF invoice by email will no longer be allowed for domestic B2B transactions.
• The mandate will apply to businesses established in Belgium or with a branch in Belgium.
• Businesses registered for VAT in Belgium but not established there will not be affected.
• The mandate only applies to domestic transactions, not cross-border transactions.
