Mandatory KSeF for Transactions with Local Governments: Invoicing Rules and Ministry Clarifications for 2026

  • The Ministry of Finance clarified rules for invoicing local government units (JST) using the National e-Invoicing System (KSeF).
  • KSeF does not require or verify the completion of the “Podmiot3” (recipient) field when JST is the buyer; only the JST as “Podmiot2” (buyer) must be indicated.
  • There is no obligation to fill in the “Podmiot3” field for invoices issued to JST.
  • This lack of system enforcement may lead to inconsistencies, errors, and disputes in financial processes between JST, suppliers, and KSeF.
  • JST and suppliers must agree on how to properly issue invoices, especially regarding the identification of subordinate units.
