IAE classification for advertising services companies and platforms

The Directorate General of Taxes (DGT) has issued a relevant ruling regarding the nature of advertising services and the operation of digital platforms to determine their correct classification within the Economic Activities Tax (IAE).

What the DGT has ruled

The inquiry raised whether the activity of operating platforms for third parties should be considered professional or business-related. Following the analysis, the DGT has established that legal entities performing activities classified in the second section of the tariffs must register under the corresponding activity in the first section (business).

Specifically, the resolution details the following registration criteria:

• Advertising services carried out through computer networks must be registered under group 844 of the first section.
• If the activity includes web page design, registration must be carried out under group 845 of the first section.

The authority emphasizes that the nature of the activity will depend on the provider's conditions and the manner in which the services are executed.

What this means for you

This ruling has a direct impact on companies operating in the digital environment. If your company provides electronic advertising services or manages the operation of platforms, you should not opt for professional classification but must register under the business section of the IAE.

An error in choosing the IAE group or section can lead to inconsistencies in the activity declaration and potential requests for information from the Tax Administration. The distinction between group 844 and 845 will depend strictly on whether the service is limited to advertising or also encompasses web design.

What should be done

It is necessary to analyze the business model and the technical execution of the services offered by your company to ensure that the IAE registration is correct. Since the nature of the activity is conditioned by the way services are provided, it is recommended to verify whether your main activity is advertising management or interface design to avoid classification errors. Each operational situation must be evaluated to determine the exact group that corresponds to your business model.
