Question
Help me understand IL / WI reciprocity: Taxpayer lives in IL, worked in WI, why wouldn't the WI taxes be fully refunded?
I have a client with a W2 where he paid $1479 in Wisconsin taxes but he was a full-year resident of Illinois. I would think that because of the reciprocity agreement between the states he would be refunded the entire $1479 on the WI return. But, he is only being refunded $480.
