In the event that you do not file a tax return IRPFABBR corresponding to the 2024 fiscal year or if the amount is 0.00 you must indicate the last five digits of the code as a verification data IBAN of a bank account in which you are listed as the account holder.

If you have any questions about how to access the confirmed draft or the submitted 2024 Income Tax return, we recommend that you follow the steps detailed in the help section "How to obtain a copy of the 2024 Income Tax return" under "Income Tax - Technical Help".

Remember that you must provide the amount corresponding to the tax return that was finally filed; if the Administration has carried out a subsequent settlement, you must provide the corresponding information from box 505.

If an error appears regarding the format of the box, we remind you that in the field intended for box 505 you must indicate the whole number without any sign, separated by a comma (,) from the decimals, for example 20724.15 as shown in the images.
