- is a resident of Illinois and files, or is required to file, a federal income tax return (regardless of net income or loss); or
- is a nonresident of Illinois but received income from Illinois sources which was not reported as pass-through withholding on Form IL-1120-ST, Form IL-1065, or Form IL-1041.

However, unrelated business taxable income, as determined under IRC Section 512, is subject to tax (without any deduction for the Illinois income tax) and must be reported on
Form IL-990-T, Exempt Organization Income and Replacement Tax Return, instead of Form IL-1041. For more information see
