For those who need to travel for business the term per diem may arise. Per diem is a Latin term meaning “per day” or “for each day.” It is a daily allowance to cover expenses when traveling for work and will vary with employers as to what is covered. A fixed per diem helps reduce the administrative costs of preparing a detailed expense report with supporting receipts to document amounts spent. The General Services Administration (GSA) is an independent agency of the United States government that establishes per diem rates for the lower 48 Continental United States (CONUS). These rates are the maximum allowances that federal employees are reimbursed for expenses incurred while on official travel. Many organizations will follow or use these rates as guidelines, since expenses will vary depending on the location of travel.
