The OPM retirement backlog: what it means if you retire soon

1. Where the backlog stands now

If you’re planning to retire from federal service soon, the OPM retirement backlog is something you need to factor into your plans — not panic over, but plan around.

Here’s the current picture. The backlog of pending retirement claims at the Office of Personnel Management peaked this winter at a record 65,237 cases in February 2026 — up 88% from the previous October. Since then it has been falling: OPM has processed more cases than it received for two straight months, and by April 2026 the backlog stood at 49,888 — the first time below 50,000 since November 2025.

That’s genuine progress. But context matters: even after the decline, that April figure is the second-highest April backlog ever recorded, behind only April 2012. The improvement is real and the direction is right — the backlog is shrinking, not growing — but the system is still working through an extraordinary volume.

What caused it: roughly 317,000 federal employees left government in 2025. The deferred resignation wave, VERA and VSIP offers, and ordinary Baby Boomer retirements all landed at once. New retirement claims more than doubled year over year. At the same time, OPM itself lost about a third of its own workforce, including roughly 100 employees from the Retirement Services division that processes these very claims. More demand, less capacity.

2. The timeline nobody budgets for

Most federal employees picture retirement as a clean handoff: last paycheck, then first pension check. The reality is a multi-stage pipeline, and the OPM retirement backlog is only part of it.

Your retirement package moves through three stages before OPM ever finalizes your annuity:

Read the first two rows carefully. Before OPM even receives your file, it has typically spent around 111 days sitting at your agency’s HR office and your payroll provider. The “OPM backlog” headline numbers only count the third stage — but the delay starts long before that.

Add it up. The pre-OPM stages plus OPM’s own processing put a realistic digital timeline near five months and a paper timeline near seven. This is why the consistent advice from federal retirement experts is the same: plan for at least six months from your separation date to your first full, finalized annuity payment. Complex cases — military service buyback, court-ordered apportionment, law enforcement special provisions — can run longer still.

The OPM backlog headline only measures the final stage. Your retirement package spends roughly 111 days at your agency and payroll office before OPM ever sees it. The clock starts the day you separate — not the day OPM receives your file.

3. Interim pay: what you actually get while you wait

Here is the part that should lower the anxiety: you are not left with zero income while your case is processed.

OPM places every immediate-retirement applicant into interim pay status, typically within about a week of receiving the application. Interim pay is a placeholder annuity — OPM’s good-faith estimate of what you’re owed — paid while specialists do the full manual review of your records.

Two things to know about interim pay:

It’s partial. Interim pay runs roughly 60% to 80% of your expected final annuity. For a retiree expecting $4,500 a month, interim pay might land between $2,700 and $3,600 — a meaningful shortfall if your budget is sized to the full amount.

It under-withholds. Interim pay only withholds federal income tax. Your FEHB, FEGLI, dental, and vision premiums are not deducted during the interim period. That makes the interim check look a little larger than your true net annuity — but it’s temporary. When your case is finalized, those premiums all begin coming out, and OPM reconciles what you owed for the interim months.

When the case is finally adjudicated, OPM pays the full retroactive back-payment — every dollar of the gap between interim and final pay, for every month you were underpaid. You don’t lose the money. But the back-payment arrives as a single lump sum in one tax year, which can complicate that year’s taxes and even nudge you into a higher bracket. It’s worth anticipating — see how retirement income is taxed for how a large one-year income event interacts with your bracket.

4. What you can actually control

You cannot speed up OPM. But several things inside your control determine whether your case moves cleanly or gets stuck:

File digitally if you can. Covered above — it’s roughly half the processing time and fewer document errors.

Submit a clean, complete package. The single most common avoidable delay is a missing or unverified document. Every time OPM has to write back asking for something, your file effectively goes to the back of the line. Before you separate, make sure your eOPF is accurate, any service-credit deposits or military buyback are paid in full, and you have clean copies of your DD-214, marriage certificate, divorce decrees, and any court orders ready to submit with the application.

Lock down your survivor election before you separate. Survivor annuity decisions add review steps, and the election should be settled — not revisited mid-process.

Track your CSA number. About four to six weeks after separation, OPM assigns your Civil Service Annuitant claim number; it appears on any OPM correspondence. If you’ve heard nothing six weeks after separating, call your agency HR to confirm your package was actually transmitted — a file stuck at the agency stage isn’t even in OPM’s count yet.

Escalate when it’s genuinely stuck. OPM’s Retirement Information Center takes status inquiries. If your case has been pending more than six months, ask for an update. Your congressional representative’s office also has OPM caseworker liaisons and can sometimes move a genuinely stalled case.

The backlog is real, and it’s a developing story — House lawmakers have an open investigation into OPM’s handling of it. But for an individual retiree, the backlog is a planning problem, not a catastrophe. File digitally, submit a flawless package, build a six-month cash bridge, and the wait becomes something you’ve prepared for rather than something that blindsides you.
