About Poland E-Invoicing

Poland's mandatory KSeF (Krajowy System e-Faktur) regime was signed into law by the President on 27 August 2025 after multiple delays. The new FA(3) schema replaces FA(2) from 1 February 2026. The rollout is phased: 1 February 2026 — large taxpayers (2024 gross sales > PLN 200M); 1 April 2026 — all other VAT-registered taxpayers (excluding micro-entrepreneurs); 1 January 2027 — micro-entrepreneurs (monthly sales < PLN 10,000). To soften the transition, penalties are deferred until 1 January 2027 (an 11-month soft landing). Four executive regulations were finalised in December 2025, covering KSeF usage, exemptions and SAF-T/invoicing amendments. Bank transfer ID references become mandatory from 1 August 2026. The 'Offline24' mode is now a permanent feature, allowing invoice upload by the next business day. A QR code is mandatory on paper or PDF representations. Foreign businesses with a Polish fixed establishment are in scope; VAT registrations without physical presence may not fall under the mandatory regime. Free interfaces and APIs are available to taxpayers.
