- KSeF 2.0 introduces optional B2C e-invoicing, permanent offline invoicing mode, mandatory QR codes for offline invoices, updated invoice format, and postponed deadlines.
- Implementation starts with open testing on September 30, 2025; mandatory e-invoicing begins February 1, 2026 for large taxpayers and April 1, 2026 for others; small taxpayers are exempt until December 31, 2026.
- Mandatory for taxpayers with a registered office or permanent establishment in Poland; VAT registration alone does not trigger the obligation.
- KSeF covers VAT invoices, corrective invoices, self-billing, and VAT RR invoices (optional from April 2026); excludes internal, pro forma, and traditional debit/credit notes.
- Cross-border sales by Polish taxpayers must be reported in KSeF, and invoices must be provided to foreign customers with a QR code.
