If an employee spends less than the Per Diem rate on a hotel they must return the difference to the government. The second form of Per Diem is Meals and Incidentals (M&IE). M&IE Per Diem is designed to cover the cost of breakfast, lunch and dinner and other miscellaneous charges one might incur while on travel. M&IE Per Diem will be paid at a pro-rated rate if employee is on travel for part of a day. Employees are allowed to keep the entire M&IE Per Diem regardless of whether they spend all of it that day.
