What is MyTax Illinois and how do I access it?

MyTax Illinois, available at mytax.illinois.gov, is a free online account management program offered by the state of Illinois to provide a centralized location for users to file returns, renew licenses, register for accounts, make payments, review correspondence, and generally manage their accounts. MyTax Illinois is utilized by the Illinois Department of Revenue (IDOR), the Illinois Department of Employment Security (IDES), and the Illinois Liquor Control Commission (ILCC). A user must create a logon to access most MyTax Illinois features, but some functions are available without creating a logon.

Most users of MyTax Illinois are individuals filing returns and making payments for Illinois Individual Income Tax. The option to file an Illinois individual income tax return without a MyTax account is improved and now available for taxpayers who file a simple return. To create a logon for MyTax Illinois, these users must have previously filed a Form IL-1040, Illinois Individual Income Tax Return, with IDOR. We encourage individuals to take the time to create a logon for MyTax Illinois as doing so allows the user to access more functionality. Logon users may file an original Form IL-1040 and access a host of features explained in MyTax Illinois Functions below.

To be able to create a logon for MyTax Illinois, a business must already have been registered with one of the Illinois state agencies listed above. If you need to register your business, you can do so using MyTax Illinois by selecting “Register a New Business (Form REG-1)” in the Register panel on the MyTax Illinois homepage and complete Form REG-1, Illinois Business Registration Application. You can then select “Sign Up” on the MyTax Illinois homepage to create your logon. Contact our Central Registration Division at 217 785-3707 for information or assistance with registering your business.

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.

To create a MyTax Illinois account, you must

• already be registered with IDOR, IDES, or ILCC to do business in Illinois if you are a business or have a recent history of filing individual income tax returns if you are an individual;
• have a tax account type currently available in MyTax Illinois; and
• know the specific business or individual identification information required for activation.

No. Activation is based on your Social Security Number (SSN) if you are a sole proprietor or your Federal Employer Identification Number (FEIN) for all other businesses. This means that all the tax types under your FEIN or SSN will be in one MyTax Illinois Account. If you get a new FEIN, you will need to re-register your business which will require you to sign up for a new MyTax Illinois Account.

If there is not yet an active MyTax Illinois account for the business, you will be considered the “Master User.” The master user has the ability to allow access to others.

IDOR transfers most requests only once a day. However, “Maintain Locations” requests and changes that the master user initiates for logon purposes (e.g. adding new logons or adjusting settings and passwords for existing logons) occur within a minute or two. Requests that are retrieved only once a day will have a status of “Pending” at the time they are made (e.g. payments or a tax return). Requests will have a status of “Completed” once they are retrieved. It takes up to five business days for balances to be updated in MyTax Illinois after payment requests are completed.

Yes. Many notices issued by IDOR are available to view, download, and print from your account in MyTax Illinois. Login to your MyTax Illinois account and select the “Action Center” section to view your letters.
