Per Diem Schedules
Per diem schedules provide meal and lodging ceilings or allowances that are location driven. The system supports multiple per diem schedules, with each schedule handling multiple locations.
Typically, per diem schedules use the US government schedules. These per diem schedules are the shared responsibility of the Department of State (DOS), the General Services Administration (GSA), and the DOD Per Diem, Travel and Transportation Allowance Committee (Per Diem Committee).
- General Services Administration (GSA) — Provides rates for the continental US locations (CONUS). GSA updates the schedule once a year, usually in October, or as necessary.
- Department of State (DOS) — Provides rates for non-US overseas locations. DOS updates these rates monthly.
- Per Diem Committee — Provides rates for non-continental US and overseas non-foreign areas. This includes Alaska, Hawaii, Guam, and so on. The Per Diem Committee updates these rates monthly.
The Per Diem Committee simplifies the process by adding DOD military installations to the rate information from DOS and GSA. At the end of the month, the Per Diem Committee provides a new Outside Continental US (OCONUS) per diem schedule, which consists of DOS (non-U.S. overseas) and the Per Diem Committee (overseas US areas) per diem rates. Once a year or as necessary, the Per Diem Committee posts the Continental US (CONUS) per diem schedule, which includes the GSA per diem rates plus rates for military installations. They publish .pdf, text, and ASCII versions of these schedules on their Web site, http://www.defensetravel.dod.mil/perdiem/perdiemrates.html. Deltek Time & Expense with ESS accepts these files for import into per diem schedules.
