Electronic filing of form 143

If you have an electronic certificate, DNI or you are registered in the Cl@ve PIN system, you can file form 143 electronically.

A request for each deduction to which you may be entitled must be filed and, in the case of dependent ascendants or descendants, a request for each ascendant or descendant who gives entitlement to the deduction.

Enter the type of deduction and the type of application. The modality selected at the time of presentation can only be modified during January. Remember that in collective applications for large families only ascendants must be entered as applicants, except in the case of orphaned siblings of parents, in which case the applicants will be. Therefore, children should not be included in the early payment applications for large families.

The other details that must be added to the advance payment request are as follows:

• The applicant's details, in the case of an individual application, or the one designated as the first applicant, if it is a collective application. In this section, the Regime or Mutual Society must be indicated, except for taxpayers who receive unemployment benefits or pensions from social welfare schemes or similar schemes who must tick the box "Not listed."
• In the case of collective applications, the data of the other applicants who also have the right to deduction.
• The IBAN code of the bank account for the payment of which the beneficiary of the advance payment of the deduction is the holder.
• The information requested in each type of application for the large family or the disabled ascendant or descendant that generates the right to deduction.

Once the application has been completed, click on "Validate."

Review the tax return details and click on "Sign and Send." A new window will appear to confirm the presentation, tick the "OK" box and click "Sign and Send."

If the submission is correct, the filing receipt will be displayed confirming the recording of the application in the register and providing the CSV (Secure Verification Code) that allows the receipt to be recovered through the E-Office's Electronic Document Verification Annex.
