How to Detect and Report Fake or Fraudulent Invoices in KSeF Before Payment

• The introduction of the National e-Invoice System (KSeF) aims to improve tax settlements but also creates new risks of receiving false or scam invoices.
• Businesses cannot reject invoices in KSeF before they are assigned to their account, increasing the risk of mistakenly paying for non-existent transactions.
• The presence of an invoice in KSeF does not have tax consequences until it is recorded in the company’s books.
• It is important to distinguish between accidental errors (e.g., wrong NIP) and intentional scams; only the former can be corrected with a corrective invoice.
• Warning signs of scam invoices include unknown issuers, transactions that never occurred, inability to contact the issuer, language errors, and unusually short payment deadlines.
