I had been working as a contract to hire, working for Company A, employed by Company B. I was then directly hired by Company A, all within a tax year.
Shortly after the transition, it was found that my address had been misrecorded as being in GA (where Company A also has an office,) and as such they almost withheld GA income tax. (I am in TN, where there is no personal state income tax.) This prompted me to check my records for Company B, and I found that they had withheld, and already remitted, quite a few months of GA Income tax.
Since I have no tax liability in my home state, I did not file a state return for the 2016 tax year, so my home state has no interest in reclaiming those funds.
Beyond calling the GA Dept. of Revenue, I am at a loss...
Clarifying Edit: I did not work in or travel for work to GA during this employment, I did, however, travel to GA at my own expense during the interview process.
