Two-Step Verification Guide

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

The security code is a security enhancement to help protect your logon. 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 logon to MyTax Illinois if you save a trusted browser.

Note: If you choose to verify using an authenticator app, you may want to set up a secondary method to get your code. If you change phones, you will need to reconnect the authenticator app to MyTax Illinois.

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 logon to MyTax Illinois, see Additional Logons below. If you are a tax professional who uses MyTax Illinois to access your client accounts, 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 logon, you can do so under “Manage My Profile.”

If you did not receive your security code:

  • If you requested your code by email, check your Spam and Junk folders. You may also need to check with your IT department to ensure you are able to receive emails from Rev.DoNotReply@illinois.gov.
  • If you can no longer use the method you have set up for receiving your security code, contact us at Rev.MyTaxHelp@illinois.gov or call Taxpayer Assistance at 1 800 732-8866 and select the appropriate tax type from the menu.
