  • IDOR Identifies Fraudulently Filed Individual Tax Returns

    ​The Illinois Department (IDOR) has recently identified a number of fraudulently filed Illinois Individual Income Tax returns. This did not result from a data breach within IDOR. Fraudulent activity is occurring nationwide due to personal information being sold on the internet's dark web. The fraudulent returns have been removed from taxpayers' accounts and those impacted are being notified. Impacted taxpayers are not required to take any additional action regarding their Illinois income taxes. IDOR will continue to monitor this situation internally. For more information about reporting and preventing identity theft, please visit IDOR's Identity Theft Information webpage.
