It depends. If you share your husband's state of residence, you will file a North Carolina nonresident return to get back all the taxes you paid to North Carolina. You only pay tax to your state of residence if there is a state tax there. You will allocate your North Carolina income as zero because of Military Spouse Residency rules. Here's an FAQ about this (click on the Joe and Mary example): https://ttlc.intuit.com/replies/3302300. You will also want to speak to your employer to fill out the correct forms so that you are only taxed in your home state and not North Carolina because of the MSRRA
However, if you do not share your husband's residency state then you will file a North Carolina resident return. North Carolina gives you the option to file either as married filing joint or married filing separately.
