The DFAS CRSC audit, explained

Information verified through September 3, 2026.

The answer up front

When the Defense Finance and Accounting Service (DFAS) says it is auditing your CRSC account, it means one of two entirely different things, and they point in opposite directions.

1. The retroactive audit. After your branch approves Combat-Related Special Compensation (CRSC), DFAS audits your account to work out what you should have been paid for prior months. This is the process that produces your back pay. DFAS states plainly that it "will audit your account to determine whether or not you are due retroactive payment," and that doing so "requires researching pay information from both DFAS and VA."
2. The periodic account audit. Separately, in DFAS's own words, it "also periodically audits CRSC and CRDP pay accounts to ensure that all adjustments were made correctly." That review can find that you were overpaid — which produces a debt letter.

Both letters look official and both mention an audit. If you are holding one, the first thing to establish is which one it is, because the retroactive audit needs patience and the debt letter needs a response inside 30 calendar days.

The retroactive audit: how DFAS builds your back pay

Your service branch decides which of your VA-rated conditions are combat-related and sets your CRSC start date. DFAS then has to convert that decision into money for every month since — and that is a manual job. From the DFAS processing-time page: "Retroactive computations require significant research and manual calculations. Our priority is to start your monthly payments, and then calculate and make any retroactive payment due. This may take 60 to 90 days after we receive all of the information."

Two practical consequences follow from that sentence, and they explain most of the anxious phone calls we field.

First, the monthly payment and the retro are separate jobs, done in that order. Your first monthly CRSC payment should be processed 60 days after DFAS receives the approval letter from your branch. The retroactive computation comes after. So the common experience — first CRSC deposit lands, no back pay attached — is the system working as designed, not a lost file.

Second, the audit crosses agencies. DFAS states that if it finds you are also due a retroactive payment from the VA, "we will forward an audit to the VA. They are responsible for paying any money they may owe you." One audit can therefore generate two payments from two agencies on two different timelines.

How far back it reaches is bounded. DFAS states the retroactive date "may go back as far as June 1, 2003," limited by your CRSC start date as awarded by your branch, your Purple Heart eligibility, your retirement date, and your retirement law. Disability retirees with fewer than 20 years of service are automatically limited to January 1, 2008. Layered on top of that, the Supreme Court's decision in Soto v. United States (No. 24-320, decided June 12, 2025) held that the Barring Act's six-year limit does not apply to CRSC — which is why retro figures since that ruling have gotten considerably larger. We covered that in the Soto decision and CRSC back pay.

The account audit: how an overpayment happens

Nothing about a CRSC debt implies wrongdoing. It is nearly always a timing artifact between two large agencies.

Here is the mechanism, in DFAS's framing. The law requires a retiree to waive gross DoD retired pay dollar for dollar against VA disability compensation — the VA waiver. When a VA rating changes, the waiver has to change with it. When the rating change is retroactive, the waiver has to change for prior months too, months in which retired pay has already been paid out at the old figure. DFAS puts it this way: because of the reporting lag between the two organizations, a rating change "nearly always creates a set of debits and credits that must be applied to prior months."

The scale is worth keeping in view. DFAS states it "receives an average of over 15,000 benefit changes each month from the VA," and that "less than 2% (on average) of those benefit changes result in a debt." A debt letter puts you in a small minority of a very large monthly volume — not in trouble.

If you get a debt letter, there are two separate lanes

This is the part almost nobody explains correctly, and getting it backwards costs people real money.

Lane 1 — Dispute the debt (hearing petition)

If you believe the debt is not valid, or the amount is wrong, or the proposed repayment schedule is unworkable, the mechanism is a written hearing petition. Under the DoD Financial Management Regulation, the petition must generally be filed no later than 30 calendar days from the mailing date of the debt notification, following the instructions in the notification letter. A timely petition matters for a concrete reason: it "will stay the beginning of collection procedures until the results of the hearing have been rendered," unless collection is judged necessary to protect the government's interests.

The first step is not the hearing itself. The debt collection office performs a reconsideration — an informal re-examination of the internal records — and issues written results. If the reconsideration validates the debt and you still disagree, you have 30 days from the date of that reconsideration letter to say you intend to proceed to a formal hearing before a hearing official.

Lane 2 — Ask the government not to collect (waiver)

A waiver is a different request entirely: you are not arguing the number, you are asking that a valid debt not be collected. It is filed on DD Form 2789, "Waiver/Remission of Indebtedness Application."

Five things about waivers that get reported wrong

1. Military members have five years, not three. Civilian employees must file within 3 years of the date the erroneous payment was discovered. Military members — active, reserve, retired, and National Guard — have 5 years from that date. The timeframe cannot be extended or waived, and "discovery" means the date an appropriate official first determined the payment was erroneous, not the date you found out.
2. Remission is not available to you. The regulation is explicit: remission or cancellation "is limited to debts resulting from overpayments of active duty pay," and is "not available for debts resulting from overpayments of military retired pay." DD Form 2789 covers both waiver and remission, but for a retiree the waiver box is the live one.
3. Financial hardship is not a waiver argument. "Economic or financial considerations play no role in the determination of a waiver request." Hardship belongs in the repayment-plan conversation, where it is genuinely relevant. It does not win a waiver.
4. Not reading your account statement can disqualify you. The standard is whether collection would be "against equity and good conscience" with no fault on your part. Adjudicators have held that a waiver will not be granted where the debtor had records that, if reviewed, would have shown the overpayment, and failed to review them — that failure makes the debtor "partially at fault and ineligible." Your monthly Retiree Account Statement is that record. This is the single most practical reason to actually open your RAS in myPay each month.
5. There is a dollar threshold and an appeal route. For military debts of $10,000 or less, the DFAS debt management office decides. Above $10,000, the decision belongs to the Defense Office of Hearings and Appeals. A denial can be appealed, but the request goes to the debt management office, not directly to DOHA, within 30 calendar days of receiving the written denial (extendable up to 30 more days for good cause). After that, no appeal is accepted.

What this means for military retirees

Three things, in order of how often they bite.

A large retro is not automatically clean money. Post-Soto retroactive awards are bigger, and bigger awards mean bigger reconciliations in both directions. If a five-figure CRSC retro lands, expect DFAS and the VA to be squaring prior months for a while afterward. Set some of it aside until the account settles rather than treating day-one arithmetic as final.

Silence is the expensive option. DFAS lists three ways to handle a debt: pay in full, set up an installment plan, or have payments deducted from your CRDP or CRSC pay. Do none of them and the debt can become delinquent — interest begins 30 days from the date of the debt notification letter, and debts delinquent more than 120 days are transferred to Treasury for collection. Starting an installment plan does not concede anything about the debt's validity; it stops the bleeding while you work the other lanes.

An audit does not raise your CRSC on its own. This one costs people the most and is the least intuitive. DFAS is emphatic: increases to your CRSC award "are not always automatic." If the VA grants new service-connected conditions, DFAS cannot add them to your CRSC — "They determine which disabilities are combat-related, not DFAS." A new VA rating without a reconsideration request to your branch means a bigger VA check and the same CRSC check. That is what a reconsideration request is for, and it is worth checking which side of your computation is actually binding before you assume a new rating changes anything.

What you should do now

Whichever letter you are holding, the first move is the same: get the documents in front of you before you get on the phone.

• Your Retiree Account Statement (RAS) from myPay — the current one and, if you can pull them, the ones spanning the period in question. Look at gross retired pay, VA waiver, and CRSC as separate lines.
• Your branch CRSC approval letter, which carries the approved conditions, percentages, and start date DFAS is working from.
• Your VA decision letters, including the effective dates of every retroactive change. The effective date is where debts come from.
• The debt notification letter itself, if you have one — note the mailing date, not the date you opened it. Your 30-day petition window runs from the mailing date.
• Any audit worksheet DFAS provided. Read the whole thing, including any offsetting credit.

Then call DFAS Retired & Annuitant Pay at 800-321-1080, Monday through Friday, 8:30 a.m. to 4:30 p.m. Eastern, and ask three questions: what period the audit covers, what the offsetting credits are, and what the deadline on your specific letter is. Get the answers in writing where you can.

One timing note worth flagging: if you are eligible for both CRSC and CRDP, your annual Open Season election letter is calculated "using the most current information we receive from the VA and your Branch of Service at the time the letters are mailed" — and you cannot switch after the deadline "even if there is an increase or decrease to one or both of your entitlements." An unresolved audit sitting over a January election is worth a phone call before you send the form back. Our CRSC vs. CRDP comparison walks through that decision, and the CRSC calculator will get you a working estimate of both.

Frequently asked questions

The bottom line

The word "audit" is doing too much work here. One CRSC audit is the machinery that pays you what you are owed, and it is slow because it is manual — monthly payment first, retro 60 to 90 days behind it. The other is a routine reconciliation that occasionally produces a debt, and the debt is usually the mirror image of a credit somewhere else in the same file.

What actually decides how those letters turn out is unglamorous: read your RAS every month, know your approval letter's start date and conditions, and if a debt notice arrives, respond inside 30 days even if the only thing you do is start an installment plan while you work out whether the number is right.

If you would like a second set of eyes on an audit worksheet, a debt letter, or a retro that does not look like the math you expected, that is a short conversation and we are glad to have it. Flat fee, never a percentage, and nothing about the first call costs anything.
