MyTax Illinois was developed, with your security in mind, to file your tax returns, make payments, and view your account information in a safe and secure manner. If you use MyTax Illinois to file a tax return, you should be aware that information received by the Illinois Department of Revenue from returns filed under the Illinois Income Tax Act and the Retailer's Occupation Tax Act (as well as most other Revenue Acts) is confidential. Accordingly, we will not disclose your tax return and account information except as required by law. However, if you choose to allow others access to your MyTax Illinois account, you do so at your own risk.
We protect the confidentiality of the tax information you provide.
MyTax Illinois requires a valid email address. We use your email address for Illinois Department of Revenue purposes only. This may be to send your authorization code when you sign up, to act as your signature on a return, or to verify your account. We do not share your email address with others or sell it for any purpose.
Note: You are not required to activate a MyTax Illinois account to file your Form IL-1040. However, if you do not activate an account, you still will be required to provide a valid email address and IL-PIN.
If you choose to activate your MyTax Illinois account, you should be the “master”, or primary user. Do not allow a tax preparer, accountant, or another person to be the “master” user on your account.
