I started 2017 working in PA as a non-resident, Jan-Sep, then returned to "home" and worked in WI 9/25/17 thru the end of the year. I'd like to file separated in PA.

My PA W2 includes taxes for both PA and WI.  Although I was married the entire year, we were "separated" while I was working the job in PA.  However, to file as separated the question asks where I lived the last six months of 2017.  I was working out-of-state for 38 weeks (yeah, one week shy of qualifying for moving expenses) but finished the year in Wisconsin.  Can I still file as separated and get most of the taxes paid in PA back?
