Non-resident or Part-Year Resident?

[paultavi]

My filing status is Married Filing Jointly for Federal Tax Purposes.  We have a home in Indiana, where I consider myself a resident (what I stated on the Federal form).  However, the majority of my time is spent in Illinois (Chicago), where I have an apartment and work full-time.  Am I considered a Non-Resident or Part-Year Resident?  I just started to do my Illinois state return and am confused by the question "Did you make money in Illinois in 2025 but never live there?"  Technically, no, because I did "live" there.  Not sure then whether to answer Yes or No.

They want to know if you have Illinois source income (which you do) but were not a domiciliary of Illinois (which you are not - you are domiciled in Indiana). So, the answer is "Yes".

Thank you for clarifying that (and for the link).  Appreciate the quick reply.
