- In 2026, businesses with monthly sales documented by invoices not exceeding 10,000 PLN (gross) can issue invoices outside the KSeF system.
- The 10,000 PLN limit includes only gross sales from invoices that must be issued in KSeF; certain invoices and receipts are excluded.
- Excluded from the limit: invoices issued via cash registers, receipts up to 450 PLN with buyer’s NIP, invoices for non-taxpayers, and simplified invoices (e.g., tickets, VAT-exempt financial services).
- After exceeding the 10,000 PLN limit in a given month, all invoices must be issued in KSeF from that point onward.
