Information on the box from the previous year’s Renta return

To request the Income Tax return reference, you must provide the amount from box 505 of the submitted 2023 Income Tax return.

Box 505 of the 2023 Income Tax Return corresponds to "General taxable base subject to tax" and not to any other amount or to the result of the return.

If you did not file a IRPF return for the 2023 financial year, or if the amount is 0.00, you must provide the last five digits of the IBAN code of a bank account in which you are listed as the holder.

If an error appears regarding the box format, we remind you that in the field for box 505 you must enter the whole number without any sign, separated by a comma (,) from the decimals , for example 12006.63.
