Nová národní verze klasifikace ekonomických činností (CZ-NACE 2025)

The new national version of the classification of economic activities (CZ-NACE 2025)

As announced by the Czech Statistical Office (ČSÚ) on December 10, 2024, the update of the CZ-NACE classification (referred to as CZ-NACE 2025) was carried out in response to the European qualification issued based on the Commission Delegated Regulation (EU) 2023/137.

The primary reason for the reclassification of economic activities was the significant structural development of the economy since the last update in 2008, as well as technological advancements in certain economic areas, the increase in digitalization, globalization, and a greater emphasis on sustainability. The new classification aims to facilitate more accurate analyses and statistical data.

The overall characteristics of NACE remain fundamentally unchanged. The CZ-NACE 2025 classification continues to have five levels, similar to the CZ-NACE 2008 version, with the first four levels based on the international standard NACE Rev. 2.1 (CZ-NACE 2008 is based on NACE Rev. 2). The fifth (specifically national) level has been supplemented by certain activities where a more detailed classification is required for statistical purposes or where the subdivision of the fourth level was requested during the consultation process.

Among the main changes are alterations in the classification structure. For instance, the previous section J (Information and Communication) has been divided into a new section J (Publishing, Broadcasting, and Content Production and Distribution Activities) and section K (Telecommunication, Computer Programming, Consulting, Computing Infrastructure And Other Information Service Activities). This change naturally resulted in a code change for all subsequent sections. Another structural change is the abolition of division 45 (Wholesale and retail trade and repair of motor vehicles and motorcycles) and the reallocation of activities classified therein to other sections. Compared to CZ-NACE 2008, there are 15 new groups and 36 new classes, while 65 subclasses have been removed.

The implementation of the new CZ-NACE 2025 classification in the Business Register (RES) is scheduled to be completed by December 31, 2025, with the recoding process of economic activities already underway according to ČSÚ. From January 1, 2026, RES will provide codes according to the new version. Given the implementation schedule of the new classification, it is currently expected that dual coding according to CZ-NACE 2008 and CZ-NACE 2025 will be maintained in RES for the necessary period, likely for four years from the introduction of the new codes. Clear algorithms for code conversion in RES will be prepared within ČSÚ, and from January 1, 2026, outputs from RES will start being automatically provided to other public databases.

Businesses will be informed about the change in their CZ-NACE through digital services, with automatic notifications sent to their data mailboxes regarding the change in RES. For business with already registered data, the reclassification should not pose an increased administrative burden. Businesses can expect to receive reclassification information from mid-October 2025 to the end of 2025.

The valid version of the CZ-NACE 2025 classification and an overview of the main changes are available on the ČSÚ website at https://csu.gov.cz.

The primary task of RES and CZ-NACE codes is to provide central and harmonized support for the selection of statistical surveys by ČSÚ. However, CZ-NACE codes are also used in other areas and by other authorities, such as in the registration of new businesses and entrepreneurs, where they help identify the main economic activity of the enterprise, financial authorities use CZ-NACE codes to identify economic activities for tax purposes, and CZ-NACE codes may be used in public procurement to define the required activities and qualifications of suppliers.
