FERS Annuity Supplement and Divorce: What OPM v. Moulton Changed

What the FERS Annuity Supplement Is and Why It Matters in Divorce

The FERS Annuity Supplement is a temporary monthly payment that bridges the gap between federal retirement and Social Security eligibility. It's paid to FERS employees who retire before age 62 with immediate, unreduced benefits — such as those retiring at their Minimum Retirement Age with 30 years of service, or law enforcement officers and firefighters retiring under special provisions.

The supplement approximates the Social Security benefit the retiree earned during their federal career. It stops at age 62, when the retiree becomes eligible for actual Social Security benefits.

For many early retirees, the supplement adds several hundred to over a thousand dollars per month to their income. In a divorce, whether this money is divisible — and under what conditions — has been one of the most contested questions in federal retirement law for the past decade.

OPM's 2016 Policy Reversal

For nearly 30 years, OPM's position was straightforward: the FERS Annuity Supplement could only be divided in a divorce if the court order expressly directed its division. If the COAP was silent on the supplement, the retiree kept 100%.

In 2016, OPM quietly changed course. The agency adopted a new interpretation: any court-ordered division of the "basic annuity" automatically applied to the FERS supplement as well — even if the order never mentioned it. OPM applied this retroactively, reducing retirees' supplements and, in some cases, demanding repayment of amounts previously distributed in full.

This created chaos for retirees who had negotiated divorce settlements years earlier based on OPM's original interpretation. A court order that explicitly addressed only the basic pension was now being used to take a portion of the supplement — a benefit that both parties may have assumed was excluded.

The Moulton Decision: October 2025

On October 10, 2025, the U.S. Court of Appeals for the Federal Circuit issued its ruling in OPM v. Moulton, rejecting OPM's 2016 policy outright.

The court held that under 5 U.S.C. §§ 8421(c) and 8467(a), OPM may apportion the FERS Annuity Supplement only when the court order expressly and explicitly provides for its division. The court found that OPM had exceeded its authority by reading the supplement into orders that were silent on the subject.

OPM did not appeal the decision before the December 23, 2025 deadline. The ruling is final and binding.

What Moulton Means Going Forward

The practical impact is clear:

If your COAP does not mention the FERS Annuity Supplement, OPM cannot divide it. The retiree retains 100% of the supplement, and the former spouse receives nothing from this income stream.

If your COAP explicitly provides for division of the supplement, OPM will divide it. The Moulton decision didn't say the supplement is never divisible — it said OPM needs explicit authorization from the court order.

For existing court orders already in effect: Retirees whose supplements were being divided under OPM's 2016 policy on silent-order grounds may be entitled to have the division reversed and back payments refunded. The specific procedure depends on whether the retiree filed a timely challenge to OPM's determination.

For new divorces being negotiated: Attorneys on both sides now know that the supplement must be explicitly addressed in the COAP. A former spouse who wants a share of the supplement needs the order to say so in clear terms. An employee who wants to retain the supplement should verify that the COAP is silent on it — or explicitly excludes it.

The Supplement Earnings Test Complicates Things Further

The FERS supplement is subject to an annual earnings test that mirrors Social Security's. If the retiree earns more than the exempt amount in post-retirement employment, the supplement is reduced by $1 for every $2 of excess earnings. The exempt amount for 2026 is $24,480.

Only earned income counts toward this test — wages and net self-employment income. TSP withdrawals, investment income, pension payments, alimony, and Social Security benefits are excluded.

When a court order does divide the supplement, the earnings test creates a secondary issue: the retiree's post-retirement work can reduce or eliminate the supplement entirely, which directly reduces the former spouse's monthly payment. This potential reduction should be addressed in the settlement negotiations, either through a floor amount or through a separate provision that adjusts the pension share to compensate.

Drafting the Court Order After Moulton

Post-Moulton, the COAP should include one of two explicit statements:

1. If the former spouse should receive a share: "The former spouse is entitled to [percentage/amount] of the employee's FERS Annuity Supplement under 5 U.S.C. § 8421."

2. If the supplement is excluded: "The FERS Annuity Supplement under 5 U.S.C. § 8421 is not subject to division and shall remain the sole property of the employee."

Either way, the order should also address how the earnings test reduction affects the former spouse's share — or explicitly state that the supplement division is independent of any earnings-test reduction.
