Per Diem refers to a daily allowance given to employees to cover expenses incurred while traveling for work. This typically includes meals, lodging, and incidental expenses. Per diem rates are often set by government agencies (like the U.S. General Services Administration (GSA) for federal employees) and vary based on the location and time of year, reflecting local cost-of-living differences. Employers may choose to follow these rates or establish their own.

Per diem payments are generally non-taxable if they do not exceed federal limits and if employees provide documentation of the time, place, and business purpose of the travel. However, any excess over the allowed rate may be considered taxable income.
