Reclassification of the Codes of Activity for Your Business (CAE Rev.3 - CAE Rev.4)

Starting on January 1st, 2025, the new Classification of Economic Activities (CAE Rev.4) will come into effect.

As part of the Information System for the Portuguese Classification of Economic Activities (SICAE), the primary and secondary economic activities of economic operators will be reclassified according to the new Codes of Activity CAE Rev.4 codes, replacing the current version, CAE Rev.3.

Until November 30, 2024, companies and entrepreneurs operating in Portugal must confirm or update their economic activity based on the new table. For this purpose, an online survey, developed by INE, is available at ircae.ine.pt. The response is confidential and mandatory.

How to respond:

1. Access IRCAE.INE.PT using your Tax Authority (AT) credentials – NIF and your Finances portal password.

2. Review the current CAE codes (CAE Rev.3) and select the CAE Rev.4 codes that best match your current business activities. Some reclassifications will be direct, and you will see a screen like this, where you can download your new codes.

3. For situations where reclassification is necessary, follow these steps:

a. Choose the status of your activity. If it was closed or suspended in 2024, choose "Em atividade."

b. Confirm your current activity code.

c. Clarify if the corresponding codes in the new classification apply to your activity. In this example, the previous classification had one code for both activities, but in the new version, they are split. Since the business focuses on accounting and fiscal consultancy, without review or audit activities, you should select accordingly:

‍

d. Confirm that no other activities are included.

‍

e. Review the summary of the new classification.

‍

f. The email field is not mandatory.

‍

g. Submit by clicking “Entregar.”

h. After submitting your response, you can download a summary/receipt in PDF format.
