Objeto social (corporate purpose)

Do not confuse it with activity codes: the CNAE classifies your activity for statistical purposes, while the IAE heading defines it before the tax agency and is declared on modelo 036. The corporate purpose can be broad, but every activity you actually carry out must be registered with the tax agency.

In practice, the objeto social is drafted when preparing the articles and is reviewed by the registrar before the company is registered. You do not need to list every service: it is enough to set out the business sectors clearly. What does not work is a catch-all formula such as «any lawful activity», because the registry will not accept it.

Example: an IT consulting SL that, after a while, wants to sell hardware. If its corporate purpose only mentions consulting services, it will have to extend it with a notarial deed and registration before it starts selling. A typical mistake is copying template articles without reading them and finding the problem only when the bank or a client asks for the deed.

It is linked to the articles of association, the Registro Mercantil, the CNAE, and the epígrafe IAE. The corporate purpose does not change how the books are kept, but it should match what you actually invoice.
