"The bank account does not appear in our database" when requesting the reference number

If you did not submit the return in the previous year or the amount in box 505 of Income 2021 is zero (0.00), it is essential that we identify you with the last 5 digits of the code IBAN of a bank account of which your Banking Entity will inform us that you are the owner.

The system will automatically detect by your NIF / NIE if this is your situation and will request the last 5 digits of your IBAN :

If the account you provide us has not been informed by the Banking Entity in its annual information return, you will not be able to request the reference number online. In that case, consult with the entity itself so that it informs the AEAT of the information.

The alternatives in this case are:

• Registration in Cl@ve . You can do it online via video call or by requesting an invitation letter from the system. After receiving it, from the Electronic Headquarters of the AEAT you have the option to register by indicating the CSV provided in the letter.
• Request an electronic certificate to carry out online procedures that require identification. It will be necessary to prove your identity at registration offices.
