Illinois Tax Season Update

The Illinois Department of Revenue began accepting 2020 state individual income tax returns on Friday, February 12th, the same day as the federal Internal Revenue Service. Please note that the filing and payment deadline for 2020 income tax returns (IL-1040) originally due April 15, 2021, was extended to May 17, 2021.

After filing your state income tax with the Illinois Department of Revenue, you can check the status of your refund with the 'Where's My Refund' application available on MyTax Illinois.

Once your return is processed at the Illinois Department of Revenue, the information is sent to the Illinois Office of Comptroller, at which time your refund will be issued. You can check the status of your tax refund payment at Find My Refund. We appreciate your patience during this process.
