The OPM Retirement Backlog Just Jumped 20%. Retiring at Year-End? Read This First.

If you've got December 31 circled on your calendar, I need you to hear this before you hand in your paperwork. Your federal employee retirement doesn't actually “start” the day you walk out the door. It starts the day OPM finishes your file. And right now, OPM just started falling behind again.

For seven straight months, the retirement backlog was shrinking. Folks were celebrating. Then October happened. The inventory jumped from 8,814 claims to 10,606, a 20% increase in a single month, according to OPM data reported by FedSmith. That's the first monthly increase since February.

And here's the thing: we haven't even hit the busy season yet. The year-end retirement wave hasn't landed. So let's talk about what this means for you, and what you can do this week so a government processing delay doesn't turn into a personal cash flow crisis.

What Just Happened at OPM (In Plain English)

Here are the October numbers, straight up:

• 10,329 new retirement claims came in during October.
• 7,004 claims were processed. That's down 47% from September and the lowest monthly total since January 2025.
• Average processing time rose to 73 days, up from 66 in September.
• Digital applications averaged about 59 days. Paper applications averaged about 150 days.

Read that last line again. Paper took more than twice as long. Same retirement, same rules, same OPM. The only difference was how the file arrived.

Now layer in history. January is consistently the month when the backlog spikes hardest. In January 2015 the inventory jumped 94%. In January 2025 it jumped 68%. Starting from roughly 10,000 claims, even an “ordinary” January could push the pile up fast. If you're retiring at the end of December, your file is walking straight into that wave.

This is not me trying to scare you. This is me telling you what the numbers say so you can plan around them like the professional you are.

Why the Wait Hits Your Wallet (And Why Nobody Explains It)

Let me be direct. The system was not designed to explain itself to you. Your agency HR office will help you fill out the forms. They will not sit down and walk you through what your bank account looks like in February, March, and April while OPM works through the stack. That's not their job. But it is your money.

While your file is pending, OPM typically pays interim pay, an estimated partial annuity. OPM reports that interim pay is set up in an average of about 6 days once a complete package arrives. That's the good news.

Here's the part nobody talks about:

• Interim pay is an estimate, and it's usually less than your full annuity. Your full amount (plus any back pay owed to you) comes after final adjudication.
• The FERS Supplement is usually not included in interim payments. If you're retiring before 62 and counting on that supplement to bridge you to Social Security, you may not see it until your case is finalized.
• “Complete package” is doing a lot of heavy lifting. A missing signature, an unresolved military deposit, or a gap in your service history can stall everything.

So picture this. Imagine a postal employee, we'll call her Denise, who retires at the end of the year assuming her first full check will land in February. Her interim pay comes in noticeably smaller than her estimate, her supplement doesn't show up for months, and she's already committed to a home repair based on her “full” number. Nothing is wrong with her retirement. Everything is wrong with her timing assumptions.

That's the cost of not knowing. Not a bad investment. A bad assumption.

Your Year-End Federal Employee Retirement Checklist

If you're retiring in the next 60 days, here's what I'd want you to do, in this order:

1. File digitally if your agency allows it

OPM's Online Retirement Application is the single biggest lever you control. The data shows digital claims moving in roughly 59 days versus about 150 for paper. Ask your HR or the Postal Service's HR Shared Service Center whether your application can go through the online system.

2. Get your file clean before it leaves your agency

Request a copy of your service history now. Check every period of service, especially military time, part-time service, and any refunded deposits. Fixing a problem before submission is days. Fixing it after OPM flags it can be months.

3. Build a cash cushion for 3 to 5 months

The full retirement process commonly runs 3 to 5 months from separation to a finalized annuity. Plan your budget around your interim number, not your estimate. Your lump-sum annual leave payout (paid by your agency, not OPM) can be a big help here if you don't spend it on the first thing that catches your eye.

4. Don't plan on the FERS Supplement in month one

Treat it as a pleasant surprise if it arrives early. Treat it as normal if it doesn't.

5. Have a TSP withdrawal plan before you need it

Your TSP can bridge a processing gap, but how you pull from it matters: which balance you tap, the tax withholding, and whether a one-time withdrawal or installments fit better. Make those choices on purpose, not in a panic in March.

The Real Enemy Isn't OPM

I'll defend OPM a little here. They're processing thousands of complex files with rules written across decades. The backlog is real, but it's predictable. And predictable problems are plannable problems.

The real enemy is the gap between what you've earned and what you've been told. Federal employees have earned one of the most powerful retirement packages in America, and the biggest threat to collecting it isn't the government. It's not knowing how to maximize what you actually have, including how to get from your last paycheck to your first full annuity without stress.

After 20, 30, or 40 years of service, you deserve a retirement that starts on your terms, not on a backlog's terms. Education is the weapon here. Once you know the timeline, the weight lifts. You stop refreshing your bank app and start actually enjoying the fact that you're retired.

So, Have You Run Your Numbers?

Here's my challenge for you this week: write down what you'd live on if interim pay were your only federal income for four months. Can you cover it? If the answer is “I'm not sure,” that's not a character flaw. It just means it's time to get clear.

Frequently Asked Questions

How long is the OPM retirement backlog right now?

At the end of October 2026, OPM's retirement inventory stood at 10,606 claims, up 20% from September. The average processing time was 73 days, with digital applications averaging about 59 days and paper applications about 150 days.

What is OPM interim pay?

Interim pay is an estimated, partial annuity OPM pays while your retirement application is being finalized. It is usually less than your full annuity, and the difference is generally paid as back pay once your case is completed.

Is the FERS Supplement included in interim pay?

Usually, no. The FERS Supplement is typically not paid until OPM finalizes your retirement, so retirees under 62 should not count on it during the first few months.

Is it a bad idea to retire on December 31?

Not necessarily. A December 31 retirement can make sense for your leave payout and annuity timing, but those files enter OPM during its busiest season. If you retire at year-end, file digitally if possible, submit a clean package, and budget for several months of interim pay.

How can I speed up my federal retirement processing?

File through OPM's Online Retirement Application if your agency supports it, verify your service history before you submit, and resolve military deposits or service gaps in advance. Complete, accurate, digital packages move fastest.
