- Poland’s KSeF (National E-Invoicing System) will become mandatory in phases starting February 2026, covering both VAT active and exempt entities for B2B and B2G transactions; B2C e-invoicing remains optional.
- KSeF 2.0 introduces legislative and technical changes, including support for optional B2C invoicing, offline invoicing capabilities, and clearer rules for cross-border and complex business scenarios.
- Four offline modes are supported to address connectivity and system issues, allowing invoice submission flexibility.
- New QR code requirements are introduced to ensure invoice authenticity and access, especially for invoices exchanged outside KSeF.
