- Poland’s National e-Invoice System (KSeF) will be implemented as scheduled, with no delays.
- The system is secure, ready, and will launch for large taxpayers (sales above PLN 200 million) on February 1, 2026.
- All other taxpayers must comply from April 1, 2026, except those with monthly invoiced sales below PLN 10,000, who join January 1, 2027.
- Only invoices count toward the PLN 10,000 threshold; consumer sales and simplified invoices up to PLN 450 are excluded.
- No penalties in 2026; sanctions begin January 1, 2027, for non-compliance. Errors can be corrected before penalties apply.
