- Poland’s Ministry of Finance launched the KSeF 2.0 Pre-production (Demo) Taxpayer Application on 15 November 2025.
- The pre-production environment allows testing with real authentication credentials and fictional invoice data, simulating conditions for February 2026.
- Key features include issuing, receiving, and viewing invoices, searching and downloading invoices, generating official receipts, QR code access, token management, and permission management.
- All invoice data in the pre-production environment must be fictional, and data is periodically deleted; permissions and certificates do not transfer between pre-production and production environments.
- The pre-production application may differ from the final version, with ongoing optimizations until the official launch on 1 February 2026.
