- In 2026, taxpayers with monthly sales documented by invoices not exceeding 10,000 PLN can issue invoices outside the KSeF system.
- The 10,000 PLN limit includes only gross sales documented by invoices that must be issued in KSeF, excluding certain types like consumer invoices, cash register receipts, and simplified invoices.
- The limit does not include sales documented by cash register reports, undocument sales, or invoices issued on request to non-taxpayers.
- After exceeding the 10,000 PLN limit in a given month, invoices must be issued in KSeF from that point onward.
