What if I need to correct or change my IL-1041?
If you need to correct or change your return after it has been filed, you must file a Form IL-1041-X, Amended Illinois Fiduciary and Replacement Tax Return. If you file the IL-1041-X on or before the automatic extended due date, mark the form "CORRECTED" at the top and show the changes. Any correction made may cause a recalculation of penalties and interest. For more information, please see Form IL-1041-X Instructions.
