I plan to file a joint federal return, it seems we must use the same filing status for NY and NJ state tax. Am I correct to assume I need to do the following for state returns:
- A joint nonresident for NY
- For NJ, I'm full-year resident and my spouse is part-year resident. If we file a joint resident return for NJ, we will also need to include the income my spouse received from Seattle, which is 18% of my spouse's annual income. Since WA doesn't have income tax, can we file NJ return separately? If it's possible, he is a part-year NJ resident, so he doesn't need to include the income received after he moved out.
