What are my rights during an audit and who may represent me?

You have the right to

  • fair, equitable, courteous, and professional treatment during the audit process.
  • an accurate determination that the correct amount of tax has been reported and paid, including overpayments, underpayments, and any errors made.
  • understand why we might request additional information, how this information will be used, and what will happen if you fail to furnish it.

You may represent yourself, or you may be represented by your employee, accountant, attorney, or any other person whom you have authorized to represent you in matters before the Illinois Department of Revenue (IDOR). Note: You must have a completed and approved power of attorney for any authorized representative on file with IDOR. For more information, visit our power of attorney web page.

If you have additional inquiries, you may submit them on the Questions, Comments, or Requests form.
