What to Actually Do If OPM Says You Were Overpaid

A monthly annuity payment feels like a settled fact, the same number, arriving reliably, for years. That reliability is exactly why an overpayment notice can be so disorienting when one finally shows up.

More Moving Parts Than Most Retirees Realize

A federal annuity calculation isn’t one number, it’s the output of several: service history, your high-3 salary, retirement system, survivor elections, former-spouse court orders, and military service credit, among others. An error in any single piece carries forward into every payment that follows it, often for years, since nothing about receiving the same check monthly signals that something upstream was wrong.

That’s the uncomfortable part of these cases. A retiree who’s received a stable, unchanged payment for a decade has every reasonable reason to assume it was correct from the start. That assumption, however reasonable, doesn’t automatically protect them once OPM catches its own error.

The Standard That Actually Matters

Federal law doesn’t treat every overpayment the same way. A waiver process exists, and two questions tend to drive the outcome: whether the retiree was actually at fault for the error, and whether forcing repayment would be against equity and good conscience given the full circumstances.

This isn’t a blanket “the government’s mistake, the government eats it” rule; waivers are fact-specific, not automatic. But one notable Merit Systems Protection Board decision found that repayment was outright unconscionable after an error sat undetected for many years through no fault of the retiree, and the debt was fully waived. That single case doesn’t guarantee any particular outcome, but it does prove the outcome isn’t predetermined the moment a notice arrives.

The Warning Signs Rarely Look Like a Big Number First

Before any large repayment demand, the actual first sign is usually smaller and easy to dismiss: a letter noting your payment amount is changing, a survivor benefit correction, a request for more documentation, or simply a check that doesn’t match what you expected. Any of those is worth stopping on, not ignoring.

This is also why keeping your own paperwork matters: retirement calculations, survivor elections, court orders, and any OPM correspondence. Those records are what let you actually verify a disputed number instead of just taking OPM’s version on faith.

If a Notice Actually Arrives

Don’t treat the number on the notice as automatically final. Ask OPM directly how it calculated the alleged overpayment, compare it against your own records, and pin down exactly when the error is claimed to have started. Consider honestly whether you had any real reason to suspect something was wrong at the time; that detail matters for a waiver request. If the amount is significant, get professional or legal guidance before agreeing to any repayment schedule; a notice states what OPM believes you owe, not whether that debt is actually enforceable as calculated.

Most retirees will never need any of this. But the protections exist precisely for the ones who eventually do.
