- Press briefings addressed misinformation about the National e-Invoice System (KSeF) and aimed to provide accurate information.
- From February 1, 2026, the largest companies must issue invoices via KSeF; smaller companies follow in April 2026, and all others by January 2027.
- KSeF is built on Polish infrastructure, uses advanced encryption, meets critical infrastructure security standards, and has passed extensive cybersecurity testing.
- The system is not a surveillance tool; it does not expand data access for authorities, only changes data processing methods.
- KSeF data is not publicly available and is processed under strict controls.
