KSeF Errors Require Corrections, Not Deletions

• KSeF has no “delete” option; if an invoice is wrong or entered by mistake, it must be corrected with a correcting invoice in KSeF.
• Even technical errors, test uploads, or mistakes made before mandatory KSeF dates still require formal correction.
• Sending the same transaction twice can create a double-invoice risk, and under VAT rules this may trigger tax on both invoices.
• KIS says duplicate KSeF invoices should be corrected “to zero” and linked by their KSeF identification numbers.
• KSeF does not replace VAT invoicing rules; it reinforces them, so taxpayers must fix errors properly rather than look for workarounds.
