- From February 1, 2026, certain transactions will not require structured invoices in the KSeF system, as specified in a new regulation by the Minister of Finance and Economy.
- The regulation lists cases of properly documented goods deliveries or services where issuing structured invoices is not mandatory, but allows for optional issuance in some cases.
- The legal basis is Article 106s of the VAT Act, effective from February 1, 2026, which empowers the minister to define such exceptions.
- The KSeF 2.0 system is fully prepared and tested for launch on February 1, 2026, with technical support and a helpline available for users.
