Poland Activates “Report Abuse” Button in KSeF 2.0 to Flag Suspect Invoices
Poland’s Ministry of Finance has activated a new functionality within the KSeF 2.0 Taxpayer Application enabling taxpayers to report invoices they suspect are fraudulent or abusive.
The feature, launched on 24th April 2026, introduces a formal mechanism for users to flag transactions directly within the national e-invoicing system.
The functionality is embedded in the invoice management workflow. Taxpayers can log into the KSeF 2.0 application, navigate to the invoice list, select a specific document and use the “Report Abuse” option.
Users are required to indicate the reason for the notification, provide a justification and confirm submission to the tax administration.
From a system design perspective, this represents an additional control layer within Poland’s centralised clearance model. While KSeF validates and stores structured invoices at the point of issuance, the new feature enables recipient-driven risk signalling post-clearance, addressing cases where fraudulent or suspicious activity may not be identifiable through automated validation rules alone.
The introduction of the reporting function forms part of the ongoing KSeF 2.0 development roadmap, and reflects feedback from businesses seeking stronger mechanisms to manage invoice-related fraud risks within the system.
The update confirms continued expansion of KSeF functionality beyond core clearance processes.
