Important E-Invoicing Milestones in 2026
Several major requirements took effect or entered a new phase during 2026. Check the complete official guidance before changing your invoicing process.
Belgium
Structured electronic invoices became compulsory on 1 January 2026 for nearly all domestic B2B transactions between Belgian enterprises liable to VAT. A normal PDF sent by email does not meet the structured-invoice requirement.

All affected businesses must be able to receive electronic invoices from 1 September 2026. Large and intermediate-sized businesses must also issue electronic invoices from that date; smaller businesses follow on 1 September 2027.

Mandatory KSeF issuance began for the largest businesses on 1 February 2026 and expanded on 1 April 2026. A temporary exception applies through 2026 to the smallest businesses below the stated monthly invoiced-sales threshold.
