- From 2026, most taxpayers in Poland must issue and receive structured invoices via the KSeF system.
- KSeF automates invoice processing but does not verify the substantive accuracy of invoices (e.g., dates, amounts, NIP).
- Errors in invoices can result in loss of VAT deduction rights and, in severe cases, criminal liability.
- The Ministry of Finance confirms KSeF 2.0 is ready and provides technical and user support.
- KSeF functions mainly as a hub for transmitting and archiving invoices, not for checking their correctness.
