Hi,
I live in Indiana and do work as a consultant for a firm located in Illinois. 100% of my income is from this work. On the 1099-NEC I received from this firm, boxes 5-7 are blank. The Payer's address is located in Illinois but all of my work is done remotely from Indiana. I don't step foot out of state to perform my duties. Do I have to file a non-resident IL return?
Thanks!
