Poland KSeF update following the January 16 press conference
On January 16, the Polish Ministry of Finance held a press conference dedicated to the National e-Invoicing System, known as KSeF. The session provided additional insight into the government’s approach to mandatory structured e-invoicing and addressed several concerns raised by businesses and software providers.
Ministers Marcin Łoboda and Zbigniew Stawicki underlined that KSeF plays a central role in Poland’s broader digitalisation strategy for tax and invoicing processes. The authorities positioned the system as a long-term foundation rather than a short-term compliance exercise, building on earlier updates to the KSeF roadmap and transition planning, as outlined in Poland KSeF update for February 2026.
Public consultation results reflected in KSeF design
One of the key messages from the press conference was the outcome of the public consultation process. According to the Ministry, approximately 98 percent of the submitted comments have been incorporated into the current version of KSeF.
This confirmation is intended to reassure companies that practical feedback from the market has materially influenced both technical and procedural aspects of the system. The Ministry stressed that the consultation was not a formal exercise but a genuine input mechanism to improve usability and feasibility, particularly as KSeF evolves towards its 2.0 architecture.
No penalties until the end of 2026
A critical clarification for businesses concerns enforcement. The Ministry confirmed that no penalties will be imposed for incorrect use of KSeF until the end of 2026.
This transition period is designed to give companies sufficient time to adapt their internal processes, update ERP integrations, and stabilise data quality without immediate financial consequences. The authorities emphasised that the absence of penalties does not remove the obligation to prepare, especially in light of upcoming structural changes such as the planned shutdown of KSeF 1.0, explained in Poland confirms KSeF 1.0 shutdown timeline ahead of KSeF 2.0.
Focus on support and gradual adoption
The press conference also highlighted the government’s intention to support businesses throughout the rollout. By allowing a penalty-free period, the Ministry aims to encourage early adoption while acknowledging the complexity of system changes required on the company side.
This approach signals a shift towards gradual adoption and controlled stabilisation, rather than strict enforcement from day one. For many organisations, this provides room to test scenarios, train users, and fine-tune invoice flows, including new functionalities such as invoice attachments under KSeF 2.0, as detailed in Poland KSeF 2.0 update on invoice attachments.
What this means for companies operating in Poland
Although penalties are temporarily suspended, KSeF remains a mandatory system with far-reaching impact on invoicing processes. Companies should use the extended transition period to ensure technical readiness, align master data, and review internal controls related to invoice issuance and receipt.
Waiting until enforcement becomes strict increases the risk of operational disruption once KSeF is fully embedded in daily business processes and integrated with core ERP and tax reporting systems.
Key takeaways
Changes companies need to implement or prepare for include:
- Treating KSeF as a structural change to invoicing processes, not a temporary compliance step
- Using the penalty-free period until the end of 2026 to test integrations and stabilise operations
- Reviewing data quality and invoice content to align with current and upcoming KSeF requirements
- Coordinating early with ERP and e-invoicing solution providers to avoid last-minute pressure ahead of KSeF 2.0
