Publication 1542: How Per Diem Rates Work for Travel Expenses

Per diem rates provide a standardized method for managing travel expenses, streamlining reimbursements without tracking individual costs. These rates simplify accounting and ensure compliance with tax regulations.

Qualifying Travel Scenarios

Eligibility for per diem rates depends on specific scenarios outlined by IRS regulations. Travel must be business-related and require an overnight stay away from the employee’s tax home. This typically involves sufficient distance and duration to necessitate rest, distinguishing it from commuting or short trips. For instance, a consultant traveling from New York to Los Angeles for a week-long conference qualifies due to the extended travel and overnight stay.

The business activity must directly relate to work duties, such as attending meetings, conferences, or training sessions. A sales representative visiting multiple client sites over several days would qualify since the travel supports their job. Personal travel or vacations, even during a business trip, do not qualify for reimbursement.

Geography also impacts eligibility. The General Services Administration (GSA) sets rates based on location, recognizing that costs vary significantly across regions. High-cost areas like San Francisco or Washington, D.C., have higher rates than smaller cities or rural areas, ensuring employees are compensated appropriately for the cost of living in their destination.

Meals and Incidentals Breakdown

Meals and incidentals constitute a major portion of reimbursable expenses. The GSA adjusts these allowances annually to reflect changing costs. For 2024, the per diem rate for meals and incidental expenses (M&IE) ranges from $59 to $79, depending on the destination. This variability ensures fair compensation without requiring employees to track every expense.

The M&IE rate covers meals and incidental costs such as tips, local transportation between lodging and dining locations, and luggage handling fees. These rates aim to cover reasonable expenses rather than luxury dining. For example, an employee attending a conference in New York would qualify for the higher end of the M&IE rate due to the city’s higher costs.

Employers can reimburse at the full per diem rate or a reduced percentage, depending on company policies. For instance, some organizations reimburse 75% of the rate on travel days to account for reduced meal needs due to travel schedules. This flexibility allows businesses to align reimbursement strategies with their budgets while adhering to IRS guidelines.

Lodging Rate Breakdown

Lodging rates, established annually by the GSA, reflect economic conditions and regional cost differences. For 2024, rates range widely, with high-demand cities like San Francisco reaching $318 per night and more modest locations as low as $98. These rates account for factors such as seasonal fluctuations and local economic conditions. For example, lodging costs may spike during peak tourist seasons or major events, and GSA adjustments accommodate such variations.

Employers can reimburse up to the maximum GSA rate or implement a capped allowance to encourage cost-effective accommodation choices. This flexibility helps maintain travel budgets while providing fair compensation for lodging.

Employer Reimbursement

Employer reimbursement for travel expenses must align with company policies and IRS regulations. Many employers choose per diem reimbursement to simplify processes and avoid tracking individual expenses. Properly structured per diem payments are excluded from income and payroll taxes under IRS rules, provided they meet the requirements of an accountable plan. These requirements include a business connection for the expenses, substantiation within a reasonable period, and the return of any excess reimbursement.

Employers must also adhere to Generally Accepted Accounting Principles (GAAP) when recording reimbursements. According to GAAP, travel expenses should be recorded in the period they are incurred, ensuring accurate financial reporting. Establishing robust internal controls is essential to prevent fraudulent claims and streamline reimbursement processing.

Documentation Requirements

Maintaining proper documentation is essential for compliance with IRS regulations when using per diem rates. While per diem rates eliminate the need to track individual expenses, businesses must still substantiate that the travel occurred and was business-related. This includes documenting the time, place, and purpose of the travel under IRS accountable plan rules.

Employees should submit detailed itineraries, including dates, locations, and the nature of the business activity. For example, an employee attending a client meeting in Chicago should provide meeting agendas or email confirmations. While lodging receipts are not required for per diem reimbursements, they can serve as supplementary evidence during audits. Standardized expense reports help ensure consistent recordkeeping.

Digital tools like Concur or Expensify can enhance documentation efforts by allowing employees to log travel details and upload supporting documents in real time. These platforms integrate with accounting systems, reducing administrative burdens while maintaining compliance.

Filing Procedures

Accurate and timely filing is critical for processing per diem reimbursements. Under an accountable plan, per diem payments are excluded from taxable income if they meet substantiation and excess reimbursement return requirements. Non-compliance can result in payments being classified as taxable wages, subject to income and payroll taxes.

Employers should establish clear policies for submitting and approving per diem claims. These policies should include deadlines, required documentation, and an approval process. For example, employees might be required to submit expense reports within 30 days of their trip, with supervisors reviewing claims before forwarding them to accounting.

Per diem payments must also be accurately reported on financial statements. Under GAAP, these expenses should be recorded as travel costs in the appropriate accounting period. Regular reconciliation of per diem payments with the travel budget helps monitor spending and identify cost-saving opportunities. By implementing efficient filing procedures, businesses can ensure compliance, streamline operations, and maintain transparency in reimbursement practices.
