НКИД 2025 Update in Bulgaria: What Companies Must Know

Bulgaria introduced a new National Classification of Economic Activities (НКИД 2025) on 1 January 2025. The National Statistical Institute (NSI) developed this system, which aligns closely with the European NACE Rev.2.1 classification. Companies should review their listed codes in the Commercial Register or Articles of Association and update them if necessary.

What Was the Previous Framework?

Before 2025, Bulgaria used НКИД 2008, based on NACE Rev.2. Companies could enter their НКИД code in the Commercial Register or Articles of Association, although the law did not require it. Many companies chose to include the code because EU funding programmes, grants, and subsidies often demanded it. Clerks at the register did not check whether the declared code matched the company’s real activity, so outdated or incorrect entries remained.

What Has Changed in 2025?

The 2025 update introduced Bulgaria’s version of NACE Rev.2.1, as required by Delegated Regulation (EU) 2023/137. Several important changes followed:

• Closer EU alignment: НКИД 2025 fully matches NACE Rev.2.1 and the global ISIC Rev.5, which ensures international comparability.
• Restructured sectors: The former sector J covering Information and communication now splits in two. Sector J focuses on Publishing, broadcasting, and content production, while sector K addresses Telecommunications and IT services. As a result, later sectors shifted their letter codes.
• Greater detail: Certain fields now use finer classifications. For instance, digital services and intermediation activities in transport gained more specific categories.
• Clearer notes: Updated methodological notes and a correspondence table now guide companies when switching from НКИД 2008 to НКИД 2025.

Examples of Continuity

Most codes remain identical to their European NACE counterparts. For example:

• A1.1.1: Growing of cereals (except rice), leguminous crops and oil seeds.
• C27.4: Manufacture of electric lighting equipment.

Although the overlap is nearly complete, some explanatory notes changed. Companies should therefore verify that their chosen code still fits their activities.

Why Does This Matter for Companies?

The НКИД code is still optional in company records. However, if a company declared one under the old system, leaving it outdated creates risks. Incorrect codes can cause problems when applying for EU funds, create inconsistencies in official records, and delay administrative procedures.

Practical Steps for Companies

Companies should act early to avoid confusion:

• Review the correspondence tables between НКИД 2008 and НКИД 2025 published by the NSI.
• Confirm that their main business activity matches the new explanatory notes.
• Update the Commercial Register and Articles of Association if the code has changed.
• Use the correct version of the code when applying for EU funding or subsidies.
• Inform relevant teams so that all internal documents reflect the updated system.
