What is KSeF?

What is KSeF?

Krajowy System e-Faktur is a central platform of the Ministry of Finance that enables issuing and storing invoices in a uniform electronic format.

The only legally valid form of an invoice is a document saved as an XML file and registered in the system. Each invoice receives a unique identification number that confirms its validity. A printout from a fiscal printer or a PDF sent by email is only a visual representation of the invoice - it does not constitute a legal document.

When does KSeF become mandatory?
