Sorry to be a bother. I understand what you're saying, however, the instructions state: "In Column B for each line, include only the portion of an amount included in Column A of that line that is non-Illinois income or deduction, as determined using Illinois’ rules for sourcing income."
So, ultimately the instructions indicate that Illinois' sourcing rule is relevant here. It's saying that there are conditions under which income would be eligible, under their rules for sourcing income. I want to know if I am eligible because the income is actually being sourced in Illinois. Most of the people that file a CR, live in IL, and then physically go to another state to work for the day or week and then travel back. This is not the case for me. I cannot find Illinois’ rules for sourcing income anywhere, which the IL-1040 Schedule CR Instructions are referring to.
