Adjustment of regulations on cash registers in Poland

Starting January 1, 2027, invoices will no longer be issued through cash registers. Instead, they must be issued exclusively via the KSeF system- e-invoicing system.

To prepare for this change, the Ministry of Finance and Economy of Poland has published a draft regulation on the RCL website. From 2027, all references to invoices and cancelled invoices — including those in fiscal reports — will be removed from the regulation.

On June 9, the Ministry of Finance held open consultations on upcoming changes to KSeF. This was the first in a series of meetings, with more dates to be announced soon.

One key proposal is to keep tokens as a permanent login method for KSeF beyond December 31, 2026. The Ministry is also considering adding expiration dates for tokens, along with the option for automatic renewal.
