    Questings

    Why is the Illinois Department of Revenue (IDOR) sending me this letter?

    We want to protect you and your identity. This is a safeguard to prevent someone from using your identity to file a false tax return to get a refund.

    Why was my return selected for additional review?

    We received an Illinois Individual Income Tax Return, filed with your Social Security number (SSN) or Individual Taxpayer Identification number (ITIN), requesting a refund. In order to protect your identity, we are requiring you to verify your information to ensure we issue the refund to the correct person.
