Two-Step Verification Guide

Why do I need to use a Security Code to sign into my MyTax Illinois account?

The security code is a security enhancement to help protect your account. When you first set up two-step verification, you can choose to receive this code by email to an address you provide,  by using an authenticator app, or via text message. A new code will be provided to you by the method you select each time you log in to MyTax Illinois. You may need to remove trusted browsers via Two-Step Security. You do not need a new code every time you log in to MyTax Illinois if you save a trusted browser.

This two-step verification ensures that only one user will have access to a username and password. If you have multiple users in your organization who need to log in to MyTax Illinois, please see Additional Logons below. If you are a tax professional who uses MyTax Illinois to access your client accounts, please see Third-Party Access below.

If you would like to set up a secondary method, such as a second email address, to verify your MyTax account, you can do so under “Manage My Profile” once you have logged in to your account.

  • If you can no longer use the method you have set up for receiving your security code, please contact us at or call Taxpayer Assistance at 1 800 732-8866 and select the appropriate tax type from the menu.
