I have a similar problem but I live overseas.
I am not an accountant. But I came across this link . Which states, according to my understanding, that even if you do not live in Illinois , you still have to pay taxes according to some rules specified in the link.
Here is a quote from this link:
"As a nonresident you are required to file Form IL-1040, Individual Income Tax Return, 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 is greater than your Illinois exemption allowance on Schedule NR), or
- you want a refund of any Illinois Income Tax withheld in error. If your employer withheld Illinois tax from your pay in error, you must attach Form W-2c, Corrected Wage and Tax Statement, or a letter from your employer, on company letterhead, to your Form IL-1040 to verify that Illinois tax was withheld in error."
Please advise.
