I did more research online. It is said : Although I have my spouse and permanent house in NY, but since I work in CT, rent a apartment there and spend more than 183 days in CT plus have driver license registered in CT, have primary doctor in CT. So I am CT only resident. And my wife lives and works in NY. She is NY only resident.
We still can file as married jointly for federal return but when goes to state tax, I should file as CT residents only with CT and my wife can file as NY residents only with NY.
Can anybody tell me is that correct?
Thanks
