Federal Retirement Planning
Waiting on OPM: How to Plan for the Cash-Flow Gap in Your First Months of Retirement
OPM retirement processing time is the stretch between your last federal paycheck and your first full FERS annuity payment. While you wait, you'll usually get a partial "interim" payment. Planning for those months ahead of time can help you retire without the stress of watching your checking account.
The Short Answer
How Long Does OPM Take to Process a Federal Retirement?
According to OPM, immediate retirement claims processed in August 2026 took an average of about 79 days. Interim pay took an average of about 6 days after OPM received a complete retirement package from the agency. Those figures leave out deferred and postponed retirements, and they change every month.
An average is still just an average. Your case could take longer or go faster, depending on how complete your paperwork is, how quickly your agency sends it over, and how complicated your service history is. We suggest planning for a gap of several months and treating a quicker finish as a bonus.
Two Numbers That Get Confused
- 1 Processing time is the average number of days OPM took to finish the cases it completed in a given month.
- 2 Inventory or backlog is how many claims are still waiting. OPM reported about 15,427 claims in inventory at the end of August 2026. Other groups publish their own counts using different methods, so those numbers aren't directly comparable.

How It Works
The Four Stages Between Your Last Day and Your Full Annuity
Your Agency Finishes Its Part
Your HR office and payroll provider review your application, add your final pay and service records, and send the package to OPM. Delays here don't show up in OPM's numbers, and this is often where a case slows down.
OPM Starts Interim Pay
Once OPM has a complete package, it usually starts monthly interim payments. OPM describes these as roughly 60 to 80 percent of your finalized net annuity for most people. It's an estimate meant to tide you over, not your real benefit.
OPM Finalizes Your Case
OPM confirms your service credit, survivor elections, and pay history, and then calculates your actual annuity. If you're eligible for the FERS supplement, it's determined as part of this step too.
Full Payments and a Catch-Up
Full annuity payments begin, and OPM reconciles what it already paid you. You may receive a back payment. Health premiums that weren't deducted during interim pay are withheld at this point, going back to your annuity start date, so that catch-up check may be smaller than you expect.

What May Arrive, and When, During Processing
Each piece of money comes from a different place on its own schedule. Seeing them side by side can help you work out how much of the gap you'll need to cover yourself.
| Income or Benefit | Who Handles It | Typical Timing | Worth Knowing |
|---|---|---|---|
| Final paycheck | Agency payroll | Normal pay cycle | Covers your last pay period worked |
| Unused annual leave payout | Agency payroll, not OPM | Often within one to two pay cycles, per OPM | Paid as a lump sum and taxable; unused sick leave isn't paid out |
| Interim annuity | OPM | Begins after OPM has a complete package | Roughly 60 to 80 percent of final net annuity for most people |
| FEHB coverage | OPM | Continues during interim pay, if eligible | Premiums withheld retroactively once the case is final |
| FERS supplement (if eligible) | OPM | Usually after your case is finalized | Generally applies to eligible immediate retirees under 62 |
| TSP withdrawals | TSP | After your separation is reported | Separate from OPM; taxes and possible penalties depend on account type and age |

Cash Flow Comes First
Three Ways to Bridge the Gap
This is where our cash-flow-first approach to federal retirement planning becomes practical. The goal is simple: know which dollars will pay which bills while OPM finishes its work. Every option below has trade-offs, and what fits depends on your own situation.
Build a Bucket 1 Cash Reserve
Setting aside several months of essential spending in cash before you retire can keep you from selling investments at a bad moment. Holding cash has a cost of its own: it can lose ground to inflation. Our bucket strategy guide explains how this fits into a longer-term plan.
Plan Around Your Leave Payout
An annual leave lump sum can cover part of the gap. Because it's taxable and lands in your retirement year, your retirement date can change your tax bill. A December versus January date is worth talking through, and our FERS retirement timing guide walks through those trade-offs.
Use the TSP Thoughtfully
Once you've separated, the TSP can be a source of cash in the meantime. Withdrawals from traditional balances are taxable, and depending on your age at separation, a penalty may apply. Large withdrawals early on can also raise your taxes. Our TSP rollover options guide compares the choices.
Where Social Security Fits
Social Security is handled by SSA, not OPM, and runs on its own timeline. If you're retiring before you plan to claim, the FERS supplement may help fill part of that space for eligible retirees. If you're not sure how the two work together, start with our explainer, Do federal employees get Social Security?, and our overview of federal retirement benefits.
Before You Submit
A Paperwork Checklist That May Help Reduce Delays
Missing or incomplete paperwork is one of the most common reasons a case slows down. Going through this list with your HR office several months before your retirement date may help, though no checklist can guarantee a timeline.
Common Questions
OPM Retirement Processing FAQs
How long does it take OPM to process retirement paperwork?
For immediate retirement claims processed in August 2026, OPM reported an average of about 79 days, and interim pay started in about 6 days on average once OPM had a complete package. Your own timeline could be longer or shorter, and OPM updates these numbers every month.
What is the current OPM retirement backlog?
OPM reported about 15,427 retirement claims in inventory at the end of August 2026. Other organizations publish their own counts with different methods, so compare numbers carefully and check OPM's monthly report for the latest figure.
How much is interim retirement pay?
OPM describes interim pay as roughly 60 to 80 percent of your finalized net annuity for most people. It's an estimate, and OPM reconciles it once your case is final, which may include a back payment and retroactive health premium deductions.
Does my health insurance continue while OPM processes my retirement?
According to OPM, FEHB coverage continues during interim pay for retirees who are eligible to carry it into retirement. Premiums aren't taken out of interim payments. OPM withholds them retroactively once processing is complete.
Why is OPM taking so long to process my retirement?
Common reasons include missing documents, unresolved service deposits, complicated service histories, and delays before your agency sends the package to OPM. Retirement volume also changes through the year, which can affect how long OPM takes.
What is the best month for a federal employee to retire?
There isn't one best month for everyone. End-of-year dates are popular because of how leave and pay periods fall, but they also mean more people are retiring at once, and the tax effect of your leave payout depends on which year it lands in. Your retirement date works best as part of a broader cash-flow and tax plan.
