- Full separation of invoicing and cash registers: Poland plans to eliminate the ability to issue invoices via fiscal cash registers, restricting them strictly to recording sales supported by fiscal receipts, in line with the KSeF e-invoicing model.
- Alignment with KSeF architecture: The reform ensures that all invoices will be issued through the National e-Invoicing System (KSeF), reinforcing centralized, structured e-invoicing and improving control and consistency in VAT reporting.
- Implementation timeline: The draft regulation was announced on 25 May 2026, with adoption targeted for Q4 2026 as part of Poland’s broader preparation for mandatory KSeF rollout.
