- Poland’s National e-Invoicing System (KSeF) is currently voluntary, with mandatory implementation delayed to 2026.
- New regulations clarify user access, authentication methods, and invoice verification, including mandatory QR codes and rules for invoices with attachments.
- From February 2026, authentication will be integrated with the National Electronic Identification Node, phasing out separate trusted electronic signature options.
- The latest regulations increase technical and process requirements for businesses and confirm KSeF’s central role in VAT control.
- Draft updates in November 2025 refine QR code requirements for invoices issued outside KSeF, narrowing when dual QR codes are needed.
