It depends. As a nonresident of Illinois, you must file a return for any taxable earnings that were derived from an Illinois source and it results in taxable income and tax liability. The regular exemption ($2,175) will be multiplied by the percentage of IL income against total income to determine if you have enough income to file. You can complete the Illinois return and if you don't have a tax liability you can choose not to file it or delete it (if you have not registered and/or paid for your TurboTax return).
A nonresident, you must file Form IL-1040 and Schedule NR if:
- you earned enough taxable income from Illinois sources to have a tax liability (i.e., your Illinois base income from Schedule NR, Step 5, Line 46, is greater than your Illinois exemption allowance on Schedule NR, Step 5, Line 50), or
- you want a refund of any Illinois Income Tax withheld in error. You must attach a letter of explanation from your employer.
NOTE: If you are a nonresident and your only income in Illinois is from one or more partnerships, S corporations, or trusts that withheld enough Illinois Income Tax to pay your liability, you are not required to file a Form
