How to Issue Invoices for Local Government Units in KSeF: Minister’s Clarifications for 2026

  • The Minister of Finance and Economy clarified how to issue structured invoices for local government units (JST) using the National e-Invoicing System (KSeF).
  • There is no obligation to fill in the “Podmiot3” (recipient) field when issuing invoices to JST; KSeF does not require or verify this section.
  • The lack of a system requirement for “Podmiot3” may cause inconsistencies, errors, and interpretation disputes between JST, suppliers, and KSeF.
  • The Ministry recommends, but does not mandate, that commercial software integrated with KSeF suggest filling in “Podmiot3” when JST is the buyer.
  • JST and suppliers must agree on invoicing practices, which may require using NIP or internal IDs for subordinate units, potentially complicating document flow and internal settlements.
