- The Ministry of Finance launched the Certificate and Authorization Module (MCU) in the National e-Invoice System (KSeF) in early November, allowing taxpayers to apply for invoice issuer certificates.
- From February 1, 2026, these certificates will enable authentication, offline invoice issuance, and QR code generation in KSeF.
- The next implementation steps include releasing the KSeF 2.0 taxpayer application for testing on November 3 and for pre-production on November 15.
- Applications for KSeF certificates can be submitted from November 1, 2025, via MCU, with specific requirements for individuals and entities, including the use of electronic signatures or seals.
- For legal entities, using a qualified electronic seal is recommended for easier authentication and certificate acquisition.
