Confused about joint state filings with spouse in different states
I have a follow-up question:
My husband lives and works in PA, so his state income is apportioned entirely to PA. I live in NJ, and work in Pa. My income is apportioned entirely to NJ, with no income to PA (at least none was apportioned to PA. We want to file joint state returns to be consistent with our Federal filing, however, when I did the taxes, it appeared that we owe taxes in NJ and PA. I believe one of us would be considered a non-resident, so I am thinking taxes should not be owed to both states, only one. Can we file a joint return for federal taxes and separate returns for state taxes? If not, who would be the non-resident? How can we achieve the greatest benefit from our joint filing given the aforementioned example?
