Question: how far do you have to be away from home to get per diem?
Answer: A per diem is money that you get to spend on food and other incidentals (including tips and phone calls). If you are away on travel for more than 12 hours and more than 50 miles from home, then you are eligible for 3/4 per diem. If you are away less than 12 hours, you do not get per diem.
