Starting March 1, 2025, self-employed individuals and businesses in Spain must review and, where appropriate, update their economic activity code according to the new National Classification of Economic Activities (CNAE-2025). This update must be reported to Social Security before June 30, 2025. Failure to do so can lead to contributions, benefits access, and regulatory compliance complications.

In this article, we’ll explore in detail what this update entails, who it affects, how to complete it, and the consequences of not complying with this obligation within the established deadline.

Deadline for update

The deadline for reporting the new CNAE-2025 code to Social Security is June 30, 2025. This update is mandatory for all self-employed individuals and companies registered before January 16, 2025. For new registrations after that date, the CNAE-2025 code must be reported at the time of registration.

What is the CNAE and why is it important?

The CNAE (National Classification of Economic Activities) is a system that classifies economic activities in Spain. This code influences aspects such as:

  • Social Security contributions: determines the contribution bases and rates for work-related accidents and occupational diseases.
  • Access to aid and subsidies: some aid is linked to specific sectors identified by the CNAE.
  • Administrative management: facilitates the organisation and accuracy of data in administrative records.

How do I perform the update?

Updating your CNAE code is done through the Social Security Importass portal. The steps are as follows:

  • Access Importass with your digital certificate, Cl@ve, or via SMS.
  • In your Personal Area, select the “Self-Employment Information” option.
  • Review your current CNAE code.
  • If necessary, select the new CNAE-2025 code that corresponds to your activity.
  • Confirm and save the changes.

In cases where the CNAE-2009 code directly corresponds to the new CNAE-2025 code, Social Security will update it automatically. However, it is advisable to verify that the information is correct.

Consequences of not performing the update

Failure to update your CNAE code can lead to various complications:

  • Contribution errors: An incorrect classification can affect the contribution bases and applicable rates.
  • Problems with Social Security coverage: especially in cases of work-related accidents or occupational diseases.
  • Difficulties accessing aid or subsidies: If you are not correctly classified, you could be excluded from certain sectoral aid.
