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.

Individuals

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 Illinois logon is improved and now available for taxpayers who file a simple return. To file a non-login return, the user must have submitted a previous year Form IL-1040, Illinois Individual Income Tax Return with IDOR. See MyTax Illinois Functions below for additional standards to file a non-login return. To create a logon for MyTax Illinois, the user must have previously filed a Form IL-1040.
