Beginning with the 2011 IL-1040, if you want to allow another person to discuss this return with the Illinois Department of Revenue, the box in Step 13 of the return will need to be checked, and the name and telephone number of the designee needs to be printed. The authorization will allow the designee to answer any questions that arise during the processing of the return, call with questions about the return, and receive or respond to notices we send. The authorization will automatically end no later than the due date for filing the following tax return. You may revoke the authorization at any time by calling or writing us.
