What is MyTax Illinois?

MyTax Illinois is a free online account management program that offers a centralized location, provided by the Illinois Department of Revenue, for businesses to register for taxes, file returns, make payments, and manage their tax accounts. Most of these features require the taxpayer to create a MyTax Illinois account. One exception is registering a new business, which must be done before you can create a username and password.

Individuals can file and/or pay their IL-1040, Individual Income Tax Return, with or without creating a MyTax Illinois account.

MyTax Illinois also contains other features that can be used without creating an account, such as looking up tax rates. For lists of these features, go to mytax.illinois.gov and use the “Individuals” or “Searches” panel.

If you have additional inquiries, you may submit them to the Questions, Comments, or Request form.
