I have two clients who are US citizens, but live abroad. Both work remotely and both had state income withholding for the state that they had previously been a resident of. I would like to file state returns so they can get a refund of the money that was erroneously withheld. I have no problem generating a state return for a resident or a non-resident getting no refund. But I'm not sure what I'm missing in order to file a non-resident state return for a refund. Any ideas? The states are GA and KS, if that helps.
