- Four executive regulations were signed regarding the functioning of the National e-Invoice System (KSeF), specifying rules for its use, notification templates, exceptions to structured invoice requirements, simplified invoice issuance, and detailed JPK_VAT data.
- Specific cases exempt from issuing structured invoices in KSeF include toll road services, passenger transport services documented by tickets, air traffic control services, certain VAT-exempt financial and insurance services, and self-billing by foreign entities without a Polish NIP.
- From February 1, 2026, simplified invoices issued in KSeF must include the issuer’s NIP; this is not required for simplified invoices issued outside KSeF to consumers.
- The regulations clarify technical limitations and special cases where structured invoices are not required, and adjust rules for VAT-exempt transactions and foreign buyers.
