Travel Stipends - What Are They & What Are The Requirements?


A travel stipend (AKA Per Diem) is a fixed sum of money given by an employer to an employee to cover travel-related expenses, such as lodging, meals, and transportation. These are offered for work-related business travel under an accountable plan, making them tax-free to a point.  

The IRS distinguishes between accountable and non-accountable plans to determine the tax treatment of employee travel stipends. For a stipend to be non-taxable, it must be part of an accountable plan that follows specific rules for business connection, substantiation, and returning excess funds. 
Accountable plan (non-taxable)
To be considered an accountable plan, the stipend or reimbursement must satisfy three requirements: 
  • Business connection: The expense must be incurred for a legitimate business purpose while the employee is performing their job.
  • Substantiation: The employee must provide proof of the expenses, such as receipts, detailing the amount, time, place, and business purpose, within a reasonable period of time (e.g., 60–120 days).
  • Return of excess funds: The employee must return any stipend amount that exceeds their substantiated expenses within a reasonable period. 
If a plan satisfies these criteria, the travel stipends or reimbursements are not considered taxable wages to the employee and do not need to be reported on their W-2. 
Non-accountable plan (taxable)
If a stipend or reimbursement arrangement fails to meet any of the three rules for an accountable plan, it is treated as a non-accountable plan. 
  • Taxable wages: Payments under a non-accountable plan are considered taxable wages, subject to income tax withholding, Social Security, and Medicare taxes.
  • W-2 reporting: The company must include the travel stipend amount in the employee's gross income on their W-2 form.
  • No expense reporting: The company does not require employees to report how they spend the money or return any unused portion.

Sources:  Many companies use the GSA Rates to simplify travel reimbursements/stipends.  The GSA Rates help to ensure that the stipends are non-taxable under the IRS rules if structured as an accountable plan.  You can review the standard rates for the city you're traveling to on the GSA site here: 

If you're a whiz at taxation laws and you don't break out into a cold sweat when tax time comes around, you're probably in the clear, but if any of the above information seems new to you or even a bit confusing its best to consult a professional.
