Steps to Register with the Tax Agency

• Where to get it: You can download model 030 from the electronic headquarters of the Tax Agency.
• Information required: You will need to provide personal data, such as your name, address in Spain, and the reason for registration.

3. Submit the Declaration

The submission of model 030 can be done in two ways:

• In person: By going to the office of the Tax Agency corresponding to your place of residence.
• Online: If you have a digital certificate or Clave PIN, you can submit the model online through the electronic headquarters of the Tax Agency.

Required Documentation

To complete the procedure, you will need to present the following documentation:

• Filled-out Form 030.
• NIE or identification document.
• Proof of residence in Spain (such as a rental contract or utility bill in your name).
