How GSA per diem works for small businesses

Trip logic

• Match a destination rate when available.
• Pick the lodging season that matches the travel month.
• Multiply lodging by the number of reimbursable nights.
• Apply 75% M&IE on the first and last day of travel.
• Use the standard CONUS rate only when the traveler or approver selects it intentionally.

Policy reminder

Your internal policy should define who approves exceptions, when receipts are required, and whether actual lodging is capped at the rate table or reimbursed separately.
