Section Voucher Audit

Why Audit Before AO Submission

The Approving Officer carries pecuniary liability for fraud or negligence in payments per MCO 4650.39AMCO 4650.39A. MCO 4650.39A An AO who certifies a defective voucher carries personal exposure. Section-level audit before AO submission protects both the Marine and the AO.

A voucher submitted to AO with errors returns to the Marine for rework. Each return cycle adds days. Each day the voucher does not pay, the GTCC ages.

The 5-Day Traveler Rule

Per JTR, the Marine submits the travel voucher within 5 working days of return from TDY. DoD JTR Ch 2 The section voucher audit fits inside that window. Audit on day 3 or 4 of return so the Marine has time to fix errors before the day-5 submission.

The 3-Day AO Settlement Window

Per current DTS process, the AO acts on the voucher within 3 working days of receipt. Disbursing settles paid vouchers per the established cycle. A voucher sitting at AO past 3 days warrants a poke from the Marine or section leader.

The AO role leaf inside this topic carries the AO-side checklist.

Pre-AO Audit Checklist

Audit each line of the voucher against the following.

• Trip dates match the orders.
• Authorization number on the voucher matches the original DTS authorization.
• Lodging within the per diem ceiling for the location, with justification attached if exceeded.
• Mileage calculation matches the JTR rate for the official distance.
• Per diem days correctly counted (departure and return days at 75 percent default).
• Rental car charged only when authorized.
• Receipts attached for all expenses over the receipt threshold (verify current threshold with S-1).
• All meals correctly accounted (proportional or M&IE, no double-claim).
• Split disbursement set ON.
• Trip purpose statement matches authorization.

A clean checklist is the basis for sending. A flagged item routes back to the Marine for fix before submission.

Common DTS Rejection Patterns

The AO returns vouchers for specific reasons. Walk the section through the patterns so Marines fix at draft.

A section that never sees these patterns has not run the audit cadence.

Receipt Documentation Standards

Required receipts.

• Lodging at any rate.
• Air, rail, or commercial transportation.
• Rental car when used.
• Any single expense over the receipt threshold (verify current threshold with S-1, the figure has shifted over the years).
• Unusual expenses requiring justification.

Receipts attach as legible scans or photos in DTS. Crumpled or unreadable receipts return at AO review.

When Receipts Are Lost

If a receipt is lost or damaged.

• The Marine submits a Lost Receipt Statement per DTS guidance.
• Attaches whatever proof exists (credit card statement, hotel folio printout, email confirmation).
• AO accepts at the AO's discretion. AO carries liability if the substitute proof is weak.

A pattern of lost receipts at one Marine warrants a coaching conversation. Receipts are routine documentation.

Section Voucher Tracker

Maintain a section-level travel voucher tracker.

Pull the tracker weekly. Surface unsubmitted vouchers past day 5 of return. Surface vouchers stuck at AO past day 3.

Common Audit Failures

• Audit deferred until AO already returned the voucher. Section discipline arrives too late.
• Receipt review skipped. AO catches the gap, voucher returns.
• Lodging over ceiling without justification. AO cannot approve without the attached statement.
• Marine submits independently without section eyes. Audit cycle never runs.

Where to Go Next

• TAD coaching for the trip-cycle context that produces the voucher.
• DTS oversight for the system mechanics.
• Claim disputes for when the voucher pays wrong.
• AO role for the SNCO or officer in the approving authority seat.
