A worldwide technology outage is causing disruption to some State of Illinois online systems.  We are aware of this issue and are diligently working on restoration.

Power of Attorney Information

Please note, if you are acting in a fiduciary capacity for a taxpayer who is unable to execute a Power of Attorney and need to represent a taxpayer before the Department, do not submit Form IL-2848. Instead, you must complete Form IL-56, Notice of Fiduciary Relationship.

In order to protect the confidentiality of tax information, we require tax practitioners, preparers, etc., to have been designated as third-party designee on a tax return on file with the Department before discussing the return with any representative. This authorization will allow you to answer any questions that arise during the processing of your return, call us with questions about your return, and receive or respond to notices we send.

If you have not been appointed as third-party designee or if you are required to perform acts beyond a third-party designation, you must be authorized as a taxpayer’s representative on Form IL-2848, Power of Attorney.
