On April 26, 2024, the Polish Ministry of Finance announced the new official implementation date for mandatory e-invoicing via KSeF during a press conference. The new timeline is as follows:
- 1 February 2026 – for taxpayers whose turnover exceeds PLN 200 million (approx. EUR 46 million) in the preceding year.
- 1 April 2026 – for all other taxpayers.
The Ministry of Finance emphasized that an earlier implementation date for the mandatory KSeF would not be feasible due to findings from an external technical audit. Consequently, the KSeF system will require a comprehensive architectural rebuild.
Further information concerning technical specifications and necessary legal amendments will be published in the coming months.
