Czech Companies Urged to Review Business Objects After NACE Update

The Czech NACE code update changes how companies classify their business activities. Although the renumbering is done automatically, it depends on the accuracy of your company’s current records. This is the right time to check that your trade licences, registry entries, and real operations all match. Fixing inconsistencies now helps you avoid issues later.

What does the Czech NACE code update involve?

The Czech Statistical Office (ČSÚ) is preparing a partial renumbering of NACE codes to align with revised classifications under NACE Rev. 2.1. Companies affected by the renumbering will receive a notification via their official data box, and the change will be processed automatically without requiring any submission or application.

However, the automatic change only works well if your records are already correct. If your Commercial Register, Trade Register, and founding documents don’t align, the new NACE code may no longer fit your real activity.

Why is this update important?

NACE codes are used in many areas: statistics, compliance reports, funding applications, and more. If they don’t match your actual activity, you could face:

• Incorrect tax or statistical reporting
• Problems with public tenders or EU funding
• Red flags in audits or legal checks

Most importantly, this update exposes old or unclear trade records. If your listed activities are too broad or vague, the newly applied code could be misleading.

How do I check if my company is affected?

Start by comparing three core documents:

1. Commercial Register – check the object of business field;
2. Trade Register – check your listed licences and any special permissions;
3. Deed of Incorporation (Articles of Association) – confirm the activity description matches the above.

Look for any gaps, outdated entries, or vague descriptions. Even if your business hasn’t changed, old language may no longer meet current rules.

How do NACE codes affect other filings?

NACE classifications can affect many external filings and obligations. For example:

• Statistical reporting submitted to authorities
• Environmental or safety obligations based on economic sector
• Sector-specific inspections or audits
• Eligibility for investment grants or subsidies

If your NACE code no longer reflects your core business, you could be excluded from these processes, or flagged for inconsistencies.

What should companies do now?

Companies should not treat this update as a passive process. Instead, they should take this opportunity to proactively validate the accuracy of their registered business activities. Legal, tax, and compliance teams should:

• Review the object of business listed in the Commercial Register, Trade Register, and Deed of Incorporation to confirm consistency.
• Ensure that trade licences list concrete activity fields, especially under the general free trade category.
• Verify that the assigned or upcoming NACE codes reflect the company’s real operational focus and are consistent across all corporate records.

Can companies correct this on their own?

Companies can handle this internally if they have access to legal, trade, and compliance expertise. However, errors in public records can lead to more serious issues if left unresolved. Many companies prefer to use expert support to avoid delays or rejections during updates.
