We have a home in NJ and I commute to NY for my Job. Mid way in 2008 my wife took a job in NC. We are keeping the NJ house and the place of residence and are renting in NC.

How do I handle the NY, NC, NJ state taxes as it relates to filing status? We plan to file jointly for federal. Is there an advantage to file as Married-filing separately for her NC state return and my NY state return? If we file jointly in all the states, will my income be a taxed in NC and her income taxed in NY?

Any help in pointing me in the right direction would be a help.
