I lived in WV until October 9th. It was then that I sold my home and moved to PA. I worked in WV until August 24th and started a job in PA on August 26th. Between August 26th and October 9th I was commuting from WV to PA and had WV taxes taken out of my paycheck in PA. On October 9th I changed my residency with my employer's payroll department and had only PA taxes coming out of my paycheck for the remainder of the year. WV state income instructions say a person is a full time resident if person "maintains a physical presence in WV for more than 183 of the taxable year, even though he/she may also be considered a resident of another state" but then also that a person is a part-time resident if "changes hes/her residence from WV to another state during taxable year". I'm confused, please help and say how certain you are in your answer :). Thanks!!

To be safe, report your worldwide on the WV tax return, and also claim credit for taxes paid to PA.
