Hi, I have a question regarding my GA state tax return. I lived in GA and all my income is from GA. My wife is a CA resident and all her income is from CA. We filed a joint return for our federal tax. But I want to file my state tax return separately since my wife is a nonresident and has no income from GA. To properly file my state tax return, I prepared a "mock" federal tax return with only my GA income to get my federal adjusted gross income that will be used for my state tax return (following this article). My question is which federal tax return copy should I include in my state tax return. My actual federal tax return (filed jointly with my wife's CA income) or my "mock" federal tax return (filed separately with my GA income only to get the AGI)? Thank you.
