Mandatory e-invoice in Poland from 2023

The new system will start operating in January 2022. It will be voluntary at the beginning, but starting January 1st, 2023, it will be obligatory.

Let us remind you, the National System of e-Invoices (KSeF) is intended to be an ICT system for receiving and storing structured invoices. After entering the invoice data, it will assign a unique identification number to the document and verify the compliance of the data contained in such an invoice with the structured invoice template. The invoice is to be considered as issued and delivered on the day the system assigns an identification number to the document.
