Let me add a little more clarity to my question.
I live and work overseas, and spend > 330 days a year outside the US. Our tax home is in Illinois and I'd like to NOT have to pay TT for the state return since my wife only receives SSDI and my income is negated by the bona fide presence test, which gives us a Federal AGI of $0.00.
So, I'm assuming that since IL is not a state that taxes SSDI payments, and our Federal AGI is $0.00, that I only have to file the 1040 and no IL state form...Right?
