Access path to procedures

Depending on the procedure of the electronic office you access, you can choose between the different identification systems available.

• Certificate or electronic DNI

  The electronic certificate is an electronic signature installed in the browser to guarantee identity and allows you to perform tasks without having to travel, such as accessing tax information, filing your tax return online, making payments, or requesting certifications directly through the Tax Agency website.

  The digital signature that includes the DNIe will allow you to carry out the same procedures as other types of electronic certificates, provided that the certificate has not expired.

  For more information about the electronic certificate and the DNIe consult the help on "Electronic certificates" and " DNI electronic ( DNIe )".

• Cl@ve Mobile

  It is an identification system that allows you to carry out procedures online based on agreed codes; specifically from the APP Cl@ve by scanning the QR code when selecting this access method, providing ID card either NIE and the requested verification data, confirming authentication also from the app or by requesting the access PIN be sent via SMS if you don't have the app installed.

• eIDAS - Access for EU citizens

  The EU Citizen Authentication System ( eIDAS ) allows citizens of one European Union country to use their national electronic ID to access public services in other member countries.

  Currently, to access the services of the State Tax Administration Agency through the eIDAS system, the EU citizen is required to have an identifier such as a DNI (National Identity Document), a NIE (Foreigner Identification Number) or a NIF L or NIF M (Tax Identification Number). This means that, although you can use your electronic ID from another EU country, you first need to have one of these Spanish identifiers to carry out procedures at the AEAT electronic headquarters.
