Poland has updated its e-invoice regulations under the National System of e-Invoices (KSeF), introducing a phased implementation timeline based on sales value, with full compliance required by April 2026. Key provisions include extended deadlines for issuing simplified invoices, offline invoicing flexibility until December 2026, and voluntary consumer invoicing. The amendments aim to ensure a smoother transition for businesses and small taxpayers while enhancing inclusivity for non-taxable entities.

The Ministry has unveiled significant updates to the mandatory National System of e-Invoices (KSeF) law, introducing a new structured invoicing framework. These changes aim to revolutionize how businesses handle invoicing, ensuring a phased and systematic transition into the future of digital finance.
Summarized phased implementation timeline for KSeF:
- The adoption of KSeF will be based on the sales value achieved in 2025, allowing businesses to adapt gradually.
- The deadline for issuing invoices through fiscal cash registers and simplified invoice processing has been extended to July 2026.
- Small Taxpayer Considerations: Small taxpayers will have the option to issue invoices in the current format until September 2026.
- Offline Invoicing: All taxpayers can issue invoices offline through a simplified process until the end of 2026, providing flexibility during the transition.
- Voluntary Consumer Invoicing: issuing consumer invoices via KSeF will remain voluntary, allowing businesses to choose the best fit for their needs.
Therefore, the deadlines are:
- February 1, 2026: The obligation will cover entrepreneurs whose sales value (including tax amount) exceeded PLN 200 million in 2025.
- April 1, 2026—the obligation will cover other entrepreneurs regardless of the sales value.
- until July 31, 2026—no obligation to provide the KSeF number in payments (also in the case of the split payment mechanism).
- possibility of issuing invoices using cash registers No penalties for failure to comply with KSeF obligations (including failure to issue an invoice in KSeF).
- until September 30, 2026—the possibility of issuing invoices in the current form for so-called "digitally excluded" taxpayers (with a small scale of activity)
- until December 31, 2026, the ability to issue invoices offline for all taxpayers.
The amendments also focus on inclusivity, ensuring that non-taxable entities can access invoices issued within the KSeF system. This provision aims to make the system more user-friendly and inclusive for a broader range of stakeholders. Businesses are encouraged to prepare for these changes and leverage the phased timelines and transitional provisions to ensure compliance.
