Poland Launches KSeF Certificates Module to Streamline Electronic Invoicing and Authorizations

  • Poland’s Ministry of Finance has launched the Certificates and Authorizations Module (MCU) in the KSeF electronic invoicing system.
  • MCU allows companies to manage authorizations, apply for, and download electronic identity certificates for KSeF use.
  • From November 1, 2025, new authorizations can only be granted via MCU; KSeF 1.0 can no longer be used for this purpose.
  • KSeF 2.0 and mandatory electronic invoicing will be required for large businesses from February 1, 2026, and for all other taxpayers from April 1, 2026.
  • Small transaction taxpayers and flat-rate farmers have later deadlines, with electronic invoicing required from January 1, 2027, and April 1, 2026, respectively.
