OPM Retirement Backlog 2026: The Complete Data Report

Last Updated: October 14, 2026 Reading Time: 14 min

Between October 2025 and September 2026, the federal retirement system absorbed the largest claims surge in its history, set an all-time backlog record, then cut that record by more than 86%. The last two legs were the steepest: August cut the pile 37.8% and September cut it another 42.9%, to 8,814, while the average wait fell to 66 days. OPM publishes this story one month at a time and explains none of it. This report assembles every month of fiscal year 2026, October 2025 through September 2026, adds two computed columns OPM does not publish, totals the year, and shows what the agency's own table does and does not account for. This is the FedTools Q3 2026 flagship data report, refreshed with the September release that closes the fiscal year.

The OPM Retirement Backlog, Month by Month (the table nobody else has)

FedTools 2026 compilation from OPM's monthly processing status report (table 1 of the September 28, 2026 document) and OPM's processing-times page. Digital share is computed by FedTools as digital claims received divided by total claims received. OPM publishes a digital-days column but no paper-days column; the only paper figures it has released are August's 150 days and September's 149, stated in each report's narrative.

Correction, September 30, 2026: the September 2025 claims-received figure is 7,095, not the 6,095 shown here since July; the inventory, processed, and days figures were unaffected. Bold marks series records (the 60-day March average remains the fiscal year's low; September's 66 ties November). The FY2026 totals are FedTools sums of the twelve monthly rows; the FYTD averages are OPM's own. August paper cases averaged 150 days and September's 149 per OPM's narrative.

Read down the columns and four separate stories emerge.

Story One: The Surge Was Bigger Than Any in History

The pre-surge system was small. September 2025's backlog of 23,552 was itself elevated; November 2024 had touched 13,844, an eight-year low, and the FY2024 backlog averaged about 16,083. OPM's own FY2025 edition of the processing table labeled the inventory column "Steady state goal is 13,000," according to the Congressional Research Service (IN12738, September 18, 2026); the FY2026 edition carries no such label.

Then the 2025 workforce reductions came due. About 154,000 employees ultimately took deferred resignation offers by OPM's later accounting (early 2025 reporting said 136,823, a figure some published analyses, including our own earlier tracker, still carry), and tens of thousands more left through VERA windows and RIFs. Deferred resignation deadlines converted into retirement applications on a schedule, and the receipts column shows it: 20,344 new claims in October, 23,393 in November, and an unprecedented 31,240 in February, five times a normal month.

For scale: the largest number of annuitants added to the retirement roll in a modern fiscal year was FY2013's 138,039 (a roll-additions measure, not applications received). FY2026 received 179,958 across the full fiscal year.

Story Two: The Processing Machine Actually Worked

The surprise of 2026 is that OPM's throughput rose to meet the wave. The processed column climbs from roughly 8,700 a month in the fall to 15,571 in January, a series record 22,237 in March, and 19,433 in May, nearly double the previous best May in the dataset era (10,954 in 2013). OPM processed 178,551 claims in FY2026, a FedTools sum of its twelve monthly rows. FY2025 had added 112,679 new annuitants to the roll; FY2026 processed far more than that.

Two mechanical changes drove it. The Online Retirement Application went from a third of new filings in October to 83.5% in September, and digital cases process faster at every point in the series. And on July 1, 2026, OPM ended paper retirement processing for more than 95% of applications, the "Last Day of Paper" after 65+ years, retiring a workflow that literally ran through a Pennsylvania limestone mine: 220 feet underground at Boyers, 221,000 square feet, 26,000 file cabinets, 400 million records, 500+ employees.

The digital transition shipped with three retiree-facing changes worth knowing:

1. A pre-retirement application: most paperwork completed before your separation date.
2. Concurrent processing: OPM starts review while your agency payroll closeout is still running, addressing part of the historical lifecycle that OPM reported at about 120 days from application start, including applicant, HR (about 60 days) and payroll (about 51 days) work.
3. A 7-day first-payment pledge: interim pay within a week of retirement for complete applications submitted by the separation date. OPM's processing-times page now lists interim pay at 6 days for September cases.

The July 1 release did not predict one thing. Paper did not stop. OPM received 1,540 paper claims in August (20.2% of intake) and 1,334 in September (16.5%), three months after the "Last Day of Paper." The digital share sat at 79 to 80 percent for three months, then reached 83.5% in September, still well short of the 95% the release described. The two figures may measure different things (the release describes what the online system can handle; the monthly report counts what actually arrived), but the plateau is real and it is why OPM still publishes a paper processing time.

Story Three: The Paradox That Ran Four Months and Stopped

From April through July the two headline columns moved in opposite directions. The backlog fell from 49,888 to 24,784 while average processing time climbed from 78 days to 109. Digital cases went from 34 days in February to 98 in July.

The working explanation was triage arithmetic. OPM cleared the clean, simple cases first, which is exactly what you want if the goal is shrinking the pile fast, and what remained was the residue of the buyout wave: applications with military service deposits, survivor elections, court orders, and incomplete records. About one in five applications arrives "unhealthy", missing documents or signatures, and many of those came from employees who departed quickly under VERA and deferred resignation without a normal pre-retirement documentation runway.

In August the pattern broke. Average time fell to 79 days, digital cases to 70, and the paper remainder came in at 150. The digital series now reads 34 (February), 96 (June), 98 (July), 70 (August). OPM has not explained the reversal any more than it explained the climb; the spring mechanics above were the working hypothesis, and OPM has neither confirmed nor rejected them. What the data does say is that the divergence we projected to persist into early 2027 did not survive past July.

The practical translation is unchanged: the single biggest thing you control is filing a complete, digital application. Our OPF review checklist covers the documents that make a file "healthy," and OPM's own error data says missing FEHB enrollment history is the top defect.

Story Four: The Record Drop, and What OPM Did and Didn't Say

Between the July and August reports the backlog fell by 9,357 cases, or 37.8%, from 24,784 to 15,427. That was the largest single-month percentage decline in the FY2026 series through August; the next largest by percentage were July (26.8%) and May (22.7%), and May's 11,341 cases remains the largest fall by count. FedSmith characterized it as the biggest monthly drop in 14 years. We cannot check that against OPM's own archive, because opm.gov serves only the current fiscal year's table, so we scope the record to the FY2026 series and attribute the longer claim.

The August report says nothing about it. Its narrative consists of three bullets: the agency is still receiving many claims on paper, it received 7,618 new claims of which 6,078 were digital and 1,540 paper, and digital cases were processed in 70 days versus 150 for paper. No press release followed. The Director Kupor quote that has circulated alongside the August numbers ("faster decisions, better service, greater transparency") comes from the July 1 "Last Day of Paper" release, ten weeks earlier.

So the obvious question is whether the drop is real or a change in how OPM counts. The table lets you check. A backlog should equal the prior month's backlog plus claims received minus claims processed. For August that arithmetic gives 24,784 + 7,618 − 15,281 = 17,121. OPM published 15,427. The difference, 1,694 cases, is unaccounted for by the published flows.

FedTools 2026 analysis of OPM's table 1. Expected backlog = prior month's published backlog + total claims received − total claims processed. OPM does not publish a reconciliation.

The gap is chronic. It averages 1,417 cases a month across the eleven transitions from November through September, the median is 1,576, and September's 1,466 is an ordinary month. Add the October transition (558 cases, from the September 2025 baseline) and the full fiscal year sums to 16,145 cases, which is more than the entire remaining backlog of 8,814. Cases leave OPM's inventory through some channel the monthly table does not show (withdrawals, cancellations, transfers to disability or death processing, and corrections are the usual candidates), and they have done so at a steady rate since October.

That is exactly why neither the August nor the September drop should be dismissed as a reporting artifact. Published receipts and processing account for 7,663 of August's 9,357-case decline (81.9%) and 5,147 of September's 6,613 (77.8%). The rest is the same unreconciled residual that appears every month. The drops are real; the flows OPM publishes explain most of them; and the part they do not explain is no larger than usual.

The fiscal-year version of that arithmetic is worth adding up. OPM received 179,958 claims in FY2026 and processed 178,551, a net +1,407 on published flows. Yet inventory fell 14,738, from 23,552 to 8,814. On the flows OPM publishes, the pile should have grown slightly. On the published flows, the whole fiscal-year cleanup sits in a 16,145-case residual that the monthly table does not reconcile, visible only when you add up the twelve rows OPM publishes one at a time. That residual rests on the September 2025 opening inventory of 23,552, which comes from OPM's FY2025 edition of the same report (row Sep-25, archived copy linked under the table above).

FedTools 2026 analysis: ending inventory ÷ that month's claims processed, from OPM's table 1. Bold marks the series high and low. The September figure is 0.57 using the trailing three-month processing average of 15,450, lower than the series-method 0.67 because September's output was the lowest since June.

OPM's pending pile is now worth about two thirds of a month of its own output: 8,814 pending against 13,227 processed in September is 0.67 months, down from 1.01 in August. In November 2025 it was five and a half months. Note that February, the record backlog month, was not the worst month by this measure; November was, because the surge arrived before the throughput did.

The paper remainder

OPM publishes the digital inventory, so the paper inventory is total minus digital. It peaked at 37,655 in February and stood at 2,911 in September, a 92.3% collapse. But paper fell only 21.7% in September while digital fell 49.6%, so paper's share of what is left rose again, from 24.1% to 33.0%.

At September's processing rates the digital pile is 0.50 months of work; the paper pile is 2.10 months. Combine that with the 149-day paper average and the conclusion for anyone still holding a paper application is plain: you are in the slow lane, and it is getting relatively slower as the digital cases drain out around you.

The Backlog Ended. Can OPM Hold It?

Our July version of this report modeled three scenarios for reaching the 13,000 steady state OPM's FY2025 table had labeled as its goal (per CRS), landing between September 2026 and January 2027. The August data made the scenario table obsolete, and the September report, which arrived September 28 rather than the early-October date we expected, answered the question outright: the backlog is 4,186 cases below that benchmark. The honest statement is narrower than "normal": 8,814 is the lowest reading in the FY2026 series, and OPM publishes nothing older than the current fiscal year to compare it with. The benchmark was OPM's own, by CRS's reading of the FY2025 table, and the system is now under it. The remaining questions are different ones:

• Does 66 days hold? It fell 43 days in two months with no stated cause, and it is not the year's low: March read 60. Two months is a direction, not a floor.
• Does the paper tail keep the average elevated? September's processed paper cases averaged 149 days and paper is now a third of the pile at 2.1 months of work; while paper cases remain a sixth of intake the blended figure will sit above the digital one.
• Does an FY2027 separation wave reset the math? Receipts have normalized to 7,600 to 10,500 a month, near the pre-surge range; September's 8,080 sits inside it. A new VERA round or the January retirement wave would push the pile back up faster than OPM's smaller staff can clear it. The October row, the first month of FY2027, is due in early November and is the first test.

That last point still rides under the optimism. GAO reporting shows OPM cut Retirement Services staffing by roughly 16% during the period the backlog fell, and 41% of OPM's under-30 staff separated between December 2024 and March 2026. The clearance surge outran the staffing loss on the strength of digital processing; the steady state now has to be held by the smaller staff through Open Season and the January retirement wave.

What This Means If You're Retiring in the Next Year

Add the stages, but treat them as averages: ~111 days of agency HR and payroll processing (OPM's January explanation) plus about 56 days at OPM for a digital case at September's pace is roughly five and a half months; paper cases run closer to eight and a half. Your own file can land on either side. The interim pay bridge covers 60 to 80 percent of your estimate in the meantime, with only federal tax withheld, and OPM's processing-times page now lists interim pay at 6 days for September cases.

Survivors wait on a different clock. OPM reports September processing of 35 days for survivor annuity applications and 129 days for survivor lump-sum claims, both up from August (32 and 109). If you are claiming a survivor annuity, plan around the 35 days; if you are claiming a lump-sum survivor benefit, plan around the 129.

File digitally and file complete. The 93-day gap between digital (56 days) and paper (149 days) in September understates the real difference, because incomplete files are what populate the slow tail. Use the pre-retirement application, and verify your record against the OPF checklist months before your date, especially FEHB enrollment history and any military deposit documentation.

Pick your date with the queue in mind. A December 2026 or January 2027 retirement lands your application in a system that closed FY2026 with less than a month of inventory; the open question is whether the January wave refills it. An end-of-year retirement also stacks the usual annual-leave-payout advantages on top; the FERS Retirement Calculator prices the annuity by retirement date, and the Federal Leave Optimizer schedules the leave you would otherwise carry into the payout.

If you're already in the queue, September's processed digital cases averaged about eight weeks at OPM, which is an average, not a promise for a file already in the queue. Status silence past three months on a file you know was complete is worth a written status request through the Retirement Services portal.

Frequently Asked Questions

How big is the OPM retirement backlog right now?

8,814 pending claims at the end of September 2026, down 42.9% from August's 15,427 and down 86.5% from February's all-time record of 65,237. That is below the 13,000 figure OPM's FY2025 processing table labeled its "steady state goal," according to the Congressional Research Service (the FY2026 table dropped the label), and the lowest reading in the FY2026 series.

How did FY2026 finish?

OPM received 179,958 retirement claims and processed 178,551 across the twelve months from October 2025 through September 2026, a FedTools total of OPM's monthly rows. Digital filings were 55.0% of receipts and 53.7% of the claims cleared. OPM reports a full-year average of 79 days overall and 62 days for digital cases.

Is 66 days the fastest OPM has processed claims?

No. September's 66-day average ties November 2025 and sits above March 2026's 60 days, the FY2026 low. It is the second-best month of the fiscal year, not the best, and OPM publishes only the current fiscal year's table, so nothing before October 2025 can be compared. OPM's September report, like August's, offers no explanation for the improvement.

How long will my retirement application take in 2026?

Plan on about 56 days at OPM for a digital application and 149 for the remaining paper cases, based on September 2026 data, plus roughly 111 days of agency HR and payroll processing before OPM receives your file. Those are dated stage averages, not a guarantee: roughly five and a half months end to end for a digital case and closer to eight and a half for paper if every stage ran at its average, with interim payments of 60 to 80 percent bridging the gap. OPM's processing-times page, now labeled for cases processed in September 2026, reports interim pay arriving in about 6 days.

What changed with OPM's "Last Day of Paper"?

On July 1, 2026, OPM ended paper-based retirement processing for more than 95% of applications after 65+ years. The Online Retirement Application processed over 155,000 applications in its first year. New with the transition: a pre-retirement application you complete before separating, concurrent processing while payroll closeout runs, and a pledge of a first interim payment within 7 days for complete applications. Paper has not vanished: 1,334 paper claims, 16.5% of September's intake, still arrived three months later (1,540 and 20.2% in August).

Does OPM's arithmetic still not add up?

No, and September is an ordinary month for it. August's 15,427 plus 8,080 received minus 13,227 processed leaves 10,280, but OPM published 8,814, a 1,466-case difference. The same gap appears in every month of FY2026 and totals 16,145 cases across the fiscal year, more than the entire remaining inventory.
