Caution: DRAFT—NOT FOR FILING 

This is an early release draft of an Illinois Department of Revenue (IDOR) tax form or instructions, which 
IDOR is providing for substitute forms providers. Do not file draft forms and do not rely on draft forms 
and instructions for filing. We incorporate all significant changes to forms posted with this coversheet. 
However, unexpected issues occasionally arise, or legislation is passed—in this case, we will post a new 
draft of the form to alert users that changes were made to the previously posted draft.  

All forms and instructions have a page on our website at Tax Forms (illinois.gov) where you may see the 
final versions once they are released. Year-end income tax forms are usually released towards the end 
of January. 

If you wish, you can submit comments and questions to IDOR about draft or final forms and instructions 
at REV.VendorForms@illinois.gov. We will forward this information to the Office of Publications 
Management, where forms and publications are administered.
