Individuals who are domiciled in PA or who are statutory residents of PA are subject to PA personal income tax on income, regardless of where the income was earned. Both residents and statutory residents may qualify for credits against tax paid to other states on income earned outside of PA.
Individuals who are neither domiciled in PA nor have statutory residency in PA are taxed only on income from sources within PA and cannot qualify for PA credits against taxes paid to other states.
