Agencia Tributaria (AEAT) Electronic Office: Who Qualifies and What You Get

Learn how to manage your tax filings and electronic notifications through the official Spanish tax portal.

The Agencia Tributaria (AEAT) Electronic Office is a digital platform used to manage tax obligations and communications with the Spanish tax authorities.

Who it's for

This service is available to all tax residents in Spain and all registered companies operating within the country.

What you get

The portal provides a way to handle various tax duties online. You can submit tax filings, manage corporate tax matters, and receive official electronic notifications.

What it costs you

While using the portal itself does not have a direct fee, you must possess a digital certificate (Certificado Digital) or a Cl@ve PIN to access the services and identify yourself securely.

The catch to know

You must check your portal regularly. Any official notifications sent to your account are legally considered "read" 10 days after they arrive, even if you never actually log in to view them.

How to apply

  1. Obtain a digital certificate (Certificado Digital) or a Cl@ve PIN.
  2. Visit the official portal.
  3. Log in using your digital credentials.
  4. Navigate to the specific tax service you need to use.
