First Time Filers

To file online, use a tax professional or tax preparation software. All you need is a valid Illinois driver’s license number or an Illinois identification card number.  

If you do not use one of these methods, you can download the tax return from our website and file a paper return.

Note: If this is the first year you are filing a Form IL-1040, your refund will be issued as a paper check.


Before You Begin

  • Complete your federal income tax return, federal Form 1040
  • Gather your W-2(s) and 1099(s) and any other tax-related documents
