Client's home state is IL. He is on military orders in PA. His income is W2 from Army and rental house in IL. Spouse has IL income and PA income. IL does not tax military income and he can use his home state for tax purposes. I believe the spouse can as well, but she did pay taxes into PA on her W2. Would I do IL tax return and PA non resident? Wasn't sure if anyone was familiar with military taxes or not. Any guidance is greatly appreciated.
