Want to check on the status of your individual Illinois income tax refund? Just provide us with your Social Security number, first and last name. We'll look through our records and let you know if we've received your information from the Illinois Department of Revenue (IDOR). We cannot issue your refund until IDOR has sent us your processed refund information. Please include your email and/or mobile phone number so we can shoot you a message to let you know that your payment is on the way!
