Mandatory B2B e-invoicing from 1 January 2028
The ZIERDED law sets mandatory B2B e-invoicing from 1 January 2028, with e-route provider requirements from 1 April 2027.
What changed and what to do
What changed
The ZIERDED law, adopted on 23 October 2025, sets the mandatory B2B e-invoicing start for 1 January 2028. Invoices will use the national e-SLOG standard or an EU-compliant syntax, sent through a registered e-route provider or PEPPOL. Requirements for e-route provider infrastructure apply earlier, from 1 April 2027. B2C and cross-border e-invoicing stay optional. An earlier 2025 proposal for a 2026 start was paused and is not part of the final law.
Who it affects
- VAT-registered businesses invoicing other businesses
- Accounting and invoicing software providers
- Companies that still send PDF invoices by email
What to do
Nothing needs to be filed today. Check whether your invoicing tool supports e-SLOG or PEPPOL and plan any move before 2028.
