FERS Retirement Application Process: From SF 3107 to Your First Annuity Check

The Process Has Five Distinct Phases

Applying for FERS retirement isn't a single event — it's a sequence of handoffs between you, your agency's HR office, the payroll provider, and OPM. Understanding who does what (and when) prevents the most common source of anxiety: the feeling that your application has disappeared into a void after you separate.

Here's what actually happens, in order.

Phase 1: Pre-Filing Preparation (12–3 Months Out)

Before you touch SF 3107, there's groundwork that determines how smoothly everything that follows will go.

12 months out: Download your entire electronic Official Personnel Folder (eOPF) and audit it. You're looking for complete SF-50 coverage — every appointment, promotion, reassignment, and change in retirement coverage should have a corresponding personnel action. Gaps in the SF-50 sequence are the single most common cause of adjudication delays because OPM cannot verify your service computation date without them.

6 months out: If you have military service, request your Estimated Earnings Statement (RI 20-97) from the military pay center and pay your post-1956 military service deposit in full to your agency's payroll office. Also resolve any outstanding civilian service deposits or redeposits for temporary or non-deduction service. These deposits must be completed before your separation date — there is no post-separation payment option.

3 months out: Schedule your pre-retirement counseling session with your agency HR office. They will generate SF 3107-1 (Certified Summary of Federal Service), which summarizes your civilian and military service, coverage codes, and sick leave balance. Review it line by line against your eOPF records.

Phase 2: Filing the Application

Since OPM's "Last Day of Paper" on July 1, 2026, the Online Retirement Application (ORA) portal is the primary filing method. Over 95% of retirement applications now flow through ORA, where the form fields mirror the paper SF 3107 sections — identifying information, service history, marital status, survivor election, insurance continuation, and direct deposit details.

Your agency HR specialist initiates the ORA case, and you complete your sections digitally. You still need physical documents for certain attachments: DD-214s, notarized SF 3107-2 (if applicable), certified divorce decrees, and the paid-in-full receipt for military deposits. These get scanned and uploaded to the ORA case or transmitted separately by your HR office.

If you're one of the limited cases still filing on paper — typically due to specific agency HR systems that haven't fully migrated — the same forms apply, but processing times are significantly longer (156 days average versus 98 for digital).

Phase 3: Separation and Payroll Handoff

On your separation date, your active pay status terminates. Within the first 30 days post-separation, your payroll provider (the National Finance Center, DFAS, or your agency's internal payroll) processes your final paycheck, including your lump-sum annual leave payout.

Between days 30 and 45, the payroll office generates and transmits your Individual Retirement Record (IRR, also known as SF 3100) to OPM. The IRR documents your complete service history, salary history, and cumulative retirement deductions. It's the authoritative record OPM uses to calculate your annuity — and it's produced by payroll, not by you or your HR office.

This step is completely outside your control, which is why it's important to know the timeline. You cannot call payroll and speed it up. But you can verify before separation that your payroll records match your eOPF, so the IRR is generated from accurate data.

Phase 4: OPM Intake and Interim Pay

Once OPM receives your application package and the IRR from payroll, several things happen in quick succession:

• OPM assigns you a Civil Service Annuitant (CSA) claim number
• You receive a letter with instructions to create a Retirement Services Online account (via Login.gov)
• OPM initiates interim payments, typically within 7–15 days of intake

Interim payments run at approximately 60–80% of your estimated net annuity. They exclude your Special Retirement Supplement (SRS), state tax withholdings, and certain insurance deductions. This is not a penalty — OPM simply cannot calculate these components accurately until full adjudication is complete. Plan for this gap by building a cash reserve before separation.

Phase 5: Adjudication and Finalization

An OPM legal administrative specialist audits your entire service record: verifying the high-3 average salary, applying sick leave credits, confirming survivor benefit elections, and computing the final annuity amount. For digital claims, this process averages 98 days from submission. The current pending inventory (as of July 2026) is about 24,784 claims, down from a peak of 65,237 in February 2026.

Once finalized, OPM issues a retroactive adjustment payment covering the difference between your interim payments and your actual annuity. Your regular monthly annuity payments — at the full calculated amount — begin after finalization. If you're eligible, the SRS also starts at this point.

What You Can Actually Control

Most of the post-separation process is out of your hands. What you can control is the quality of the package that goes in. Applications with complete documentation, accurate service histories, and properly notarized forms clear adjudication faster than those missing even one attachment.

The FERS Retirement Application Guide structures this preparation into a chronological pre-filing audit — checking your eOPF, verifying your service computation date, and assembling supporting documents in the order your agency and OPM will need them.
