- From February 2026, Polish VAT taxpayers will be required to use the National e-Invoice System (KSeF) for invoicing. A new regulation by the Minister of Finance and Economy will govern the use of KSeF, including permissions, authentication, invoice marking, and technical requirements. The regulation is currently undergoing public consultations and inter-ministerial agreements. The need for this regulation arises from changes to the VAT Act, which mandates the use of KSeF starting February 2026.
