How do I report tax fraud?

Tax fraud or misuse of licenses affects us all by providing an unfair advantage to tax cheaters. There are three different ways you may report this crime:

  1. Fill out a Fraud Referral Form online.
  2. Send your complaint in writing to:
    BUREAU OF CRIMINAL INVESTIGATION
    ILLINOIS DEPARTMENT OF REVENUE
    101 WEST JEFFERSON STREET
    PO BOX 19014
    SPRINGFIELD IL 62794-9014
  3. Call 1-800-CHEAT-11 (1-800-243-2811). Note: If our agents are unavailable when you call, you may leave a message. If you leave a message and require a response, please leave your contact information including a phone number where we can reach you.

Please note: Complaints regarding improper claiming of dependents, fraudulent activity by non-Illinois residents or other issues related to the federal income tax return should be reported to the Internal Revenue Service (IRS) at 1 800 829-1040 or www.irs.gov.

For Child Support call 1 800 477-4278 or visit www.childsupportillinois.com.
