To correct, complete, or modify the self-assessments filed for 2024 personal income tax, once the necessary modifications have been made in the "Modify 2024 Income Tax Return Already Filed" section of Renta Web, select the corrective self-assessment option.
Generally, you don't need to enter any data manually, as Renta Web automatically retrieves the receipt numbers, the income previously computed in each case, and any previously agreed refunds, and displays the corrective self-assessment result.
