I have a client that was transferred to Georgia at the beginning of 2019.  She has an apartment and bought a car in Georgia.  Her husband and three children live in their home in California and won't move to Georgia until all of kids are out of school.  I'm not sure how to go about preparing this return.

Her gross income in box 1 of the W-2 is $299,365.  The California income in box 16 is $156,326.  The Georgia income in box 16 is $241,741.  The math doesn't work but her company says income was apportioned and wouldn't necessarily match gross.  Hmmm.  California will of course want to tax the entire amount since her family and real estate is in California and there should be a tax credit for tax paid to another state. I guess I should file a non resident return for Georgia.  Should I just ignore the California income in box 16 and then she will pay taxes on the gross plus have to pay Georgia taxes on the$241,741.

Am I making this more confusing than it is?
