In brief

• From 1 January 2027, only the PKD 2025 classification will apply.
• Entrepreneurs with old codes in the registers may update them free of charge, by submitting a request themselves.
• Automatic conversion in CEIDG and KRS may not correctly cover all entries.

Is an entry from 2025 enough?

Not entirely. Currently, entrepreneurs may use both PKD 2007 codes and the new PKD 2025 codes in the registers (Od 2027 r. obowiązkowe stosowanie kodów PKD 2025.

The transitional period ends on 31 December 2026, and from the following day only the new classification will apply ([Nowa klasyfikacja PKD 2025.

What to do if the entry contains old codes?

Simply submit a request to update the entry. The change is free of charge and can be carried out independently. There is no need to wait for the CEIDG or KRS system to convert the data automatically, because that conversion may happen later, and not all entries will be transferred correctly.

Who is affected by the obligation?

The change concerns entrepreneurs whose entries in the registers still contain PKD 2007 codes. The new classification itself applies from 1 January 2025, so companies that operated under the old codes had time to adapt earlier.

Why shouldn't you delay?

If the change is not made before the end of the year, the data in the registers may, once the old codes are phased out, stop reflecting the company's actual activity. Practical questions and answers on this topic have been prepared, among others, by the editors of GazetaPrawna.pl.
