- Poland will implement mandatory e-invoicing via the KSeF system in phases starting February 2026.
- Large businesses (sales over PLN 200 million in 2024) must use KSeF from 1 February 2026; all other businesses from 1 April 2026.
- Businesses with monthly invoiced transactions under PLN 10,000 are exempt from issuing via KSeF until end of 2026, but must receive invoices through the system from February.
- No penalties for incorrect KSeF use until the end of 2026; extensive consultations and support activities are ongoing.
