How to Review Mileage Reimbursement Claims

A sound mileage review verifies that a claimed trip was business-related, that the distance and calculation can be followed, and that the same travel cost has not also been claimed in another form. It is a targeted evidence review, not an invitation to collect location history unrelated to work. Organizations should consult their applicable policy and jurisdiction for mileage rates, eligible travel, recordkeeping, and any local requirements; this guide does not prescribe a rate or determine eligibility under a particular rule.

Confirm trip purpose and eligibility

Read the stated business purpose and identify the work destination, date, and reason the employee traveled. Compare these details with the assignment, meeting, or other business context available to the reviewer. Apply the organization's policy to determine whether the trip type qualifies; do not infer eligibility from distance alone. If a journey includes both business and personal stops, ask for the business portion and the method used to separate it when policy calls for that distinction.

Reconstruct the claim from its supporting record

Check that the submission identifies the vehicle or method required by policy, travel date, origin and destination or other required route description, business purpose, and claimed distance. Review a contemporaneous mileage log, calendar or appointment context, route record, or other evidence the organization accepts. Compare the entered distance with a reasonable route estimate when appropriate, but recognize that route choice, closures, and stops may explain a difference. Record what evidence was actually reviewed instead of presenting an estimate as proof of the driven route.

Check arithmetic and overlapping costs

Recalculate the submitted distance using the rate applicable under the organization's policy for that trip and period. Confirm that units are consistent and that the amount follows the documented calculation. Then check whether fuel, rental, parking, tolls, or another travel charge is separately submitted in a way that the policy treats as overlapping or separately eligible. Do not assume that every additional travel cost is prohibited; compare each item with the applicable policy and retain the rationale.

Worked example: a client visit with a personal stop

An employee reports a round trip from the office to a client site and notes a personal errand on the return. The reviewer sees the meeting invitation, the date, a route description, and the employee's mileage log. The policy directs employees to exclude personal travel. The reviewer asks the employee to identify the business route and separate the personal detour; the employee provides the business distance and explains a road closure that accounts for a small route difference. The reviewer recalculates using the organization's applicable rate, checks that fuel was not also claimed contrary to policy, and records the review. If the employee cannot support the split, the item remains pending for clarification rather than being approved on an assumed distance.

Return, correct, or escalate with a clear reason

For a missing route, unclear purpose, or arithmetic error, return only the relevant question and say what record or correction is needed. Keep the original submission and corrected version traceable. Escalate questions about policy interpretation, suspected duplicate payment, or unusual route circumstances to the designated finance or policy owner. Where a jurisdiction-specific question affects the review, consult qualified internal guidance or the appropriate adviser; do not invent a local rule. Record the final distance, calculation, reviewer, and disposition.
