Can I file a joint Georgia return if my spouse and I have different residency statuses?
Yes.
If one spouse is a full year resident and the other is a part-year resident, file as Part-year resident.
If one spouse is a full or part-year resident and the other is a nonresident, file as a Part-year resident and enter the Georgia residency dates 01/01 to 01/01 for the nonresident spouse.
