Meal tips incurred by the traveler are included in the subsistence allowances. Housekeeping tips are not allowed. Tips for handling baggage at common carrier terminals and tips for the handling of baggage when arriving at or departing from the place of lodging can be claimed separately and must be itemized under the “Other Expense” section of the travel reimbursement form.
Reimbursable gratuity or tips must be considered reasonable for items that are not already covered under subsistence. Excessive tips will not be reimbursed. A reasonable tip would be one that a prudent person would give if traveling or conducting personal business and expending personal funds.
For additional information on tips, please review the Travel Manual, Section 6.5 on Tips.
