What if I need to correct or change my Form IL-990-T?

If you need to correct or change your return after it has been filed you must file Form IL-990-T-X, Amended Exempt Organization Income and Replacement Tax Return, for the appropriate tax year. Any correction made may cause a recalculation of penalties and interest. For more information refer to the Form IL-990-T-X Instructions for the tax year you wish to amend.
