How can I ensure that my foundation’s travel expenses remain “reasonable and necessary”? - Exponent Philanthropy

How can I ensure that my foundation’s travel expenses remain “reasonable and necessary”?

To ensure your foundation’s travel expenses comply with IRS regulations, Exponent Philanthropy recommends adopting a clear travel and expense reimbursement policy that:

  • Encourages cost-effective travel choices.
    The IRS requires that foundation travel expenses not be “lavish or extravagant.” Trustees and staff should opt for reasonable transportation and lodging.

  • Defines eligible travel activities and sets limits.
    Your policy should specify which types of activities are reimbursable—such as board meetings, site visits, or conferences—and outline any limits on the number of trips per year.

  • Clarifies which expenses are and aren’t reimbursable.
    For example, the foundation may cover coach airfare but not first-class, or allow reimbursement for meals but not alcoholic beverages.

  • Applies the policy uniformly to all representatives of the foundation.
    The policy should apply to anyone incurring expenses on the foundation’s behalf—but not their spouses, dependents, or other family members. The foundation cannot legally reimburse travel for these “disqualified persons” unless they are also conducting official foundation business.

  • Outlines required documentation and approval processes.
    Specify what documentation is needed (e.g., itemized phone bills for long-distance board calls) and who is responsible for reviewing and approving reimbursement requests.

As an alternative to reimbursing actual expenses, the IRS permits foundations to use per diem allowances for meals and lodging to simplify recordkeeping.

Keep in mind that special rules may apply to certain expenses, such as car allowances, security costs, and international travel. Always consult your foundation’s attorney when drafting or updating your travel reimbursement policy.
