My son in law worked in Indiana temporarily for 7 months in 2011 for his Georgia employer. His employer withheld Indiana taxes and I assume issued him an IN W-2 (haven't seen it yet but his Georgia W-2 does not have all his income.) His wife remained here in Georgia and we consider this to be his tax home and are deducting the temporary living expenses. For Georgia filing, do we treat him as a full year resident or part year resident?
