Incidentals

Incidentals (or incidental expenses) are additional expenses incurred by a business traveler that are not included in the core cost of accommodation, transportation, or other trip elements. 

Unlike airfares or hotel room rates, incidentals arise from personal or work-related expenses during a trip. They may include in-room beverages, parking fees, taxis, tips, and other costs that are necessary or convenient during the trip but are not part of the travel policy arrangement. 

Incidentals are often tracked separately to ensure accurate expense management within the organization.

Organizations often establish policies outlining what qualifies as an acceptable incidental expense and set per diem limits or reimbursement procedures.
