My sister works as a TSA screener at the airport. Now they send her out to different states doing the same thing Transportation Security Administration. Gets free room and board so much money for food plus per diem. She made about 14000.00 in per diem and 38000.00 in groos wages. Now does she have to claim the per diem on her federal taxes. She lives in Tennessee. She makes different amounts of per diem per state. Thank You Judy
