On January 16, the Ministry of Finance of Poland held a press conference on the implementation of the KSeF National e-Invoice System, which is is a tool for issuing, sending, receiving, and storing structured invoices.

The obligation to issue invoices in the KSeF will be introduced in stages:

– from April 1, 2026, it will apply to other businesses.

Until the end of 2026, taxpayers whose transactions documented by invoices do not exceed a total gross monthly sales value of PLN 10,000 (EUR 2,300) will be exempt from the obligation to issue invoices in the KSeF.
