Generally, if you qualified for a federal Earned Income Tax Credit (EIC), you also qualify for the Illinois EIC. You must complete
Schedule IL-EIC, Illinois Earned Income Credit, to figure your credit amount.
We will review the EIC you claim and we may ask you to provide additional information such as:
- your city-, state-, or county-issued professional license, registration, or certification (if required for your occupation)
- sales, business, or withholding tax registration forms
- your federal return
- your federal Schedule C or Schedule C-EZ
- your federal Form 8867 (if you used a paid preparer to file your return)
- documents you used to calculate your business income and expenses (ledger, spreadsheet, journal, sales slips, receipts, etc.)
Please do not attach this information to your originally-filed Form IL-1040, Individual Income Tax Return. If necessary, we will send you a letter requesting additional documents in order to verify your EIC.
