- Until December 31, 2026, invoices outside KSeF are allowed if monthly sales on such invoices do not exceed 10,000 PLN.
- All taxpayers must receive invoices via KSeF from February 1, 2026, with some exceptions and transitional periods.
- The Director of the National Tax Information clarified that issuing an invoice outside KSeF does not automatically block the right to deduct VAT.
