Some actions in MyTax Illinois require pop-ups to be enabled in your browser. For example, the Help Menu will open in a new browser window to display help options. Or, if you are trying to view returns, letters, and documents, they will open in a new browser window. To allow pop-ups in your browser, please see your browser’s help menu for instructions.
Note: If you see a screen that says “Retrieving your letter…” and has a countdown, click on the link that says “If your letter does not open automatically, click here.”
If you have successfully enabled pop-ups in your browser and are still having trouble accessing these MyTax Illinois features, you can call us at 1 800 732-8866 or 217 782-3336 or email us at REV.TA-Sales@illinois.gov.
