- Poland will introduce a mandatory e-invoicing system (KSeF) for most VAT taxpayers starting in 2026.
- KSeF aims to digitalize invoicing, improve accounting processes, and combat VAT fraud by enabling real-time verification of VAT settlements.
- The system is unique to Poland and not based on other EU e-invoicing systems.
- Invoices must be issued in a standardized XML format and sent to a central database, where they are stored for 10 years.
- Implementation will be phased: large taxpayers from February 1, 2026; most others from April 1, 2026; and the smallest taxpayers from January 1, 2027.
