Protecting Illinois Taxpayers

Our enhanced efforts to protect Illinois taxpayers from identity theft and tax fraud have proven to be highly successful. We will continue to combat the criminals attempting to steal your identity to file fraudulent tax returns while making every effort to get your tax refund to you as quickly as possible.

Please remember, filing your return electronically and requesting direct deposit is still the fastest way to receive your refund. You can file for free using MyTax Illinois, our online account management program for taxpayers. For more information, go to mytax.illinois.gov or visit our website.
