The benefits of Poland’s new national invoicing system


Tax refund will be shortened by 20 days, from 60 to 40.


Invoices will be stored in the Ministry of Finance database, preventing damage or loss.

Accelerated turnover:

Structured invoices can be received and processed faster and more accurately, leading to timely or early payment.


Structured invoices give taxpayers the full benefits of end-to-end process automation.


Mutual settlements and invoice booking are more manageable on the Krajowy System e-Faktur platform.

Fewer obligations:

Taxpayers will not have to manually store invoices, as the administration will automatically archive them for 10 years.

Less data to be sent to the tax authorities:

Taxpayers will not have to generate audit files (JPK_FA), as these will be available for authorities in the system.
