Federal Employee Retirement Checklist: The 12-Month Countdown

Federal retirement is not a single decision — it is a 12-month process of verifications, elections, and filings that, done correctly, can add tens of thousands of dollars to your lifetime annuity and prevent catastrophic losses of FEHB, survivor benefits, or service credit. Done poorly, it produces regret that cannot be undone: a missed military buy-back that costs $200/month forever, a stale beneficiary designation that leaves the wrong person the TSP balance, or a delayed retirement application that pushes your annuity commencing date back months. This checklist walks through what to do in each of the 12 months before your retirement date, with statutory references to 5 USC § 8334 (military deposits), § 8342 (annuity computations), § 8401 et seq., § 8414 (FERS eligibility), § 8424 (commencing dates), § 8442 (TSP), § 8905 (FEHB), § 8701 et seq. (FEGLI); 5 CFR § 831, § 839, § 842, § 844, § 845, § 846, § 890; and the OPM Federal Employees Retirement System Handbook.

Why a 12-month countdown matters

Federal retirement is governed by statutory deadlines and processing timelines that an employee cannot accelerate at the end. Three timing pressures force a long runway:

• Military service credit deposits under 5 USC § 8334 and 5 CFR § 831.2103 typically take 3–6 months from submission of DD-214 to OPM interest calculation to final payment posting. Without the deposit posted before retirement, the time is not creditable.
• The SF 3107 retirement application should reach your agency HR 60–90 days before your retirement date. Late submission delays your annuity commencing date (5 CFR § 842.203), and you receive no annuity until processing completes — interim payments begin only after OPM receives the package.
• FEHB and FEGLI elections at retirement are irreversible. If your coverage is wrong at retirement, you cannot retroactively add it. The 5-year FEHB rule (5 USC § 8905(b)) cannot be satisfied retroactively.

OPM's average processing time for a FERS retirement is currently 50–70 days from agency separation to first full annuity payment. During the gap, you receive no income except any saved leave lump-sum payout. A 12-month runway lets you time your retirement date so the gap falls in a manageable month.

According to OPM's FERS Handbook, the most common cause of delayed first annuity payment is incomplete retirement application packages — missing DD-214s, unsigned survivor elections, or stale beneficiary forms. The 12-month checklist exists to catch these.

Month 12: Verify SCD and service computation

Your Service Computation Date (SCD) determines how many years of creditable service you have for retirement eligibility and annuity computation. The SCD for retirement (SCD-Ret) is different from the SCD for leave (SCD-Leave) — confusing, but they live in different systems. The SCD-Ret appears on your Personal Statement of Benefits from OPM, accessible via Services Online or your agency's HR system.

What to verify at Month 12:

• SCD-Ret reflects all creditable service: civilian service, military time (if bought back), redeposited refunded service, and any unused sick leave (under FERS, sick leave is credited in hours, converted to days, and added to service time but only for annuity computation, not eligibility — 5 USC § 8415(c)).
• No gaps from non-pay status exceeding 6 months in a calendar year (5 CFR § 831.301 — non-pay time over 6 months breaks creditable service continuity unless elected to be credited with deposit).
• Temporary time recredit if you had any non-deduction temporary service after 1988 (FERS). A deposit under 5 CFR § 842.305 may make it creditable.
• Sick leave balance — verify the balance your HR shows matches your own records. Under 5 USC § 8415(c), FERS sick leave is fully creditable (100%) for retirements on or after January 1, 2014. Earlier retirements receive 50% credit (or 25% if retired before October 28, 2009 — a transitional rule).

If your SCD-Ret is wrong, file a written request to your HR to correct it now. Post-retirement corrections are possible but slow — OPM must adjudicate the dispute, which can take 6–12 months and may delay your final annuity computation.

Month 11: Buy back military time

Military service performed before 1957 is fully creditable without a deposit. Military service performed after 1956 requires a military service deposit under 5 USC § 8334(a) and 5 CFR § 831.2103 to be creditable for FERS retirement. The deposit equals 3% of military base pay for service after 1956 (the FERS employee contribution rate during the military period), plus interest accruing from October 1, 1986 (or the date of FERS coverage, if later).

The deposit process has four steps:

1. Obtain your DD-214 for each period of service. Order online from the National Archives if you do not have copies.
2. Submit Form RI 20-97 ("Estimated Earnings During Military Service") to your branch's finance office. They return an estimated earnings statement within 30–60 days.
3. Submit the estimated earnings to your agency HR with Form SF 3108 ("Application to Make Deposit"). OPM computes the deposit amount including interest and notifies your agency.
4. Pay the deposit via lump sum or payroll deductions. Payroll deductions must complete before your retirement date.

Worked example: a 4-year enlistment in 1988–1992 with average base pay of $18,000/year produces military earnings of approximately $72,000. The 3% deposit is $2,160. With interest accruing from October 1986 at variable rates (currently 2.75% in 2024, set annually under 5 CFR § 831.105), the total deposit is roughly $6,000–8,000. Buying back 4 years of service adds 4 × 1% × high-3 to your annuity — for a $120,000 high-3, that is $4,800/year, every year for life. Payback period: under 2 years.

If you do not buy back military time, the years are not creditable — but if you retire before age 62 and receive Social Security based on that military service, the years may count for Social Security computation only. The military deposit is one of the highest-ROI investments a federal employee can make.

Month 10: Review TSP contributions and catch-up

The 2024 TSP elective deferral limit is $23,000 (5 USC § 8442; IRC § 402(g)). Employees aged 50+ may contribute an additional $7,500 catch-up for a total of $30,500 in 2024. SECURE Act 2.0 added a "super catch-up" for ages 60–63 of $10,000 (indexed) beginning in 2025.

What to do at Month 10:

• Maximize contributions if you have not been doing so. Even a few months of higher contributions can compound meaningfully.
• Verify you are receiving the full 5% agency matching. FERS employees get: 1% automatic agency contribution + 100% match on first 3% you contribute + 50% match on next 2% = 5% agency contribution when you contribute at least 5%. Employees contributing less than 5% are leaving free money on the table.
• Confirm Roth TSP election if you want tax diversification. You can split contributions between traditional and Roth in any percentage.
• Review investment allocation. TSP Lifecycle (L) funds are age-appropriate target-date funds; many retirees shift toward more conservative allocations as retirement approaches. The G Fund (government securities) is risk-free but historically returns below inflation.
• Update Form TSP-3 beneficiary designation. This controls who receives your TSP balance at death. A divorce, marriage, or birth does not change your TSP-3 — only a new form does.

After retirement, you cannot contribute to TSP. So this is the last window to maximize tax-advantaged savings. The Roth TSP is particularly valuable for retirees expecting to be in a high bracket in retirement or anticipating tax increases.

Month 9: Update beneficiaries on TSP-3, SF 3102, FEGLI

Three beneficiary forms control who receives different federal benefits at your death. Each form is independent — updating one does not update the others.

Common beneficiary mistakes:

• Estate as beneficiary. Names the estate as TSP beneficiary, forcing the balance through probate. Direct individual beneficiaries avoid probate and give the surviving spouse more flexible options (a spouse beneficiary can keep the funds in a "Beneficiary Participant Account" with TSP).
• Ex-spouse still listed. Divorced years ago, never updated TSP-3. The ex-spouse inherits the TSP balance — there is no automatic update on divorce.
• Minor children as direct beneficiaries. A minor cannot manage TSP funds directly; a guardianship proceeding is required. Better: name a trust or an adult custodian under UTMA.
• No contingent beneficiaries. If the primary beneficiary predeceases you and you have not named a contingent, the funds pass to your estate.

Update all three forms at Month 9 — leaving time for any paperwork to be processed before retirement. Keep copies of all submitted forms.

Months 8–7: Counseling and the FEHB 5-year rule

Schedule retirement counseling through your agency HR or a contracted provider 6–8 months before retirement. The session should cover eligibility verification (5 USC § 8412–8414), high-3 computation (highest 3 consecutive years of basic pay — locality and within-grade increases count, bonuses generally do not), annuity estimates, survivor benefit election options (5 USC § 8340, § 8420), FEHB and FEGLI continuation rules, TSP withdrawal planning, and the FERS Special Retirement Supplement (5 USC § 8421). Bring your latest SF 50, TSP statement, Services Online annuity estimate, DD-214 if applicable, and FEHB enrollment code. If agency counseling is perfunctory, hire a private counselor with the Chartered Federal Employee Benefits Consultant (CFEBC) designation — fees of $300–600 typically pay back many times over in optimized elections.

At Month 7, verify the FEHB 5-year rule under 5 USC § 8905(b) and 5 CFR § 890.302: you must have been continuously enrolled in FEHB (as the enrollee, not as a family member) for the 5 years immediately before retirement. Any break in coverage — even a 1-day gap — can disqualify you. Confirm your enrollment is at Self Plus One or Self and Family if your spouse needs survivor continuation; Self Only at retirement means the surviving spouse cannot continue FEHB. Review plan options during Open Season (mid-November to mid-December); FEHB premiums are projected to rise 5–7% annually. Exceptions under 5 CFR § 890.302(b) exist but are narrow (e.g., military activation). If you are within 5 years of retirement and not enrolled, enroll in the cheapest Self Only plan immediately and upgrade to Self Plus One before retirement.

The FEHB 5-year rule is the single most common reason retirees lose health coverage in retirement. Unlike other rules, it cannot be cured retroactively — the 5 years must actually pass with continuous enrollment.

Months 6–5: FEGLI review and annuity estimate

FEGLI (Federal Employees' Group Life Insurance, 5 USC § 8701 et seq.) has four coverage tiers: Basic (annual basic pay rounded up to next $1,000 plus $2,000, costing 2 cents per $1,000 per pay period with the agency paying ⅔); Option A ($10,000 flat); Option B (1–5 multiples of annual basic pay, with cost rising sharply with age — at 60+, Option B costs 10× what it costs at 35); and Option C (1–5 multiples for spouse and children). At retirement, you can continue Basic (with reduction) at no cost if you had coverage for 5 years; the death benefit declines 2% per month starting at age 65, dropping to 75% by default or 50% with higher premiums. Options A/B/C continue only if elected before retirement and paid by you.

Common planning move at Month 6: comparison-shop private term life insurance. If you are healthy, private term is often 50–80% cheaper than FEGLI Option B for the same death benefit. A 20-year term policy for $500,000 usually beats FEGLI Option B at 5× salary, especially after age 55. You can also convert FEGLI to private insurance without underwriting within 31 days of separation under 5 CFR § 870.802.

At Month 5, get a precise annuity estimate — not the ballpark from Services Online, but a complete computation including the survivor election reduction (5% for partial 25%, 10% for full 50%), the FERS Special Retirement Supplement under 5 USC § 8421 if retiring before age 62 with 30+ years, net annuity after federal tax withholding (unless you file Form W-4P), and estimated COLAs based on CPI-W projections. Use the FERS Federal Pension Estimator to run scenarios with multiple retirement dates — retiring 90 days later can change your high-3 if a pay raise falls within the new period. Also model the survivor scenario: what happens to household income if you die first, if your spouse dies first, or if both live to 90?

Month 4: Plan tax strategy

Federal annuities are taxable as ordinary income for the portion attributable to government contributions (5 USC § 8331 note; IRC § 72). The employee contribution portion — the money you paid in over your career — is returned tax-free under the "Simple Life Expectancy" method described in IRS Publication 721. Key tax planning items at Month 4:

• Estimate federal and state tax liability for the year of retirement. A retirement date early in the calendar year often produces a lower-income year — a good Roth conversion opportunity.
• State of residence — nine states have no income tax; many states exempt federal annuities. Relocating at retirement can save 5–10% of gross income annually.
• TSP tax treatment — review traditional vs. Roth split, plan withdrawal sequence to minimize bracket creep.
• Annual leave lump-sum payout — capped at 30 days for most employees (5 USC § 6304(d)), 60+ for SES. Taxed as ordinary wages in the year received.

Unused sick leave is not paid out as a lump sum — it is added to your service computation date for annuity purposes only. If you expect a major tax event (large TSP withdrawal, large annual leave payout), talk to a tax professional about estimated tax payments to avoid underpayment penalties.

Month 3: Submit the SF 3107 retirement application

SF 3107 (Application for Immediate Retirement) is the formal retirement application for FERS employees. The full application package includes:

1. SF 3107 — Application for Immediate Retirement (employee data, beneficiary elections, signature).
2. SF 3107A — Survivor Benefit Election (if married, must be completed with spousal notarized signature if electing less than full 50% survivor).
3. SF 3118 — FERS Transfer Information (if you transferred from CSRS to FERS).
4. Certified Summary of Federal Service — agency-prepared document verifying your SCD-Ret, creditable service, and high-3.
5. DD-214s if military service is being credited.

Submit the package to your agency HR at least 60 days before your retirement date. The agency has 30 days to certify and forward to OPM under 5 CFR § 842.204. OPM then takes 30–60 days to process and begin annuity payments.

Critical: specify your retirement date precisely. Your annuity commencing date is the first day of the month after you separate. If you retire June 30, your annuity begins July 1 and is paid at the end of July — meaning you receive no annuity in July (you receive your first check at the end of August, for July's annuity). Plan cash flow accordingly. Many retirees set the date for the last day of a pay period that maximizes accrued annual leave.

You cannot un-submit the application after the retirement date passes. Withdrawal before the effective date is permitted, but after the date, you are retired.

Months 2–1: Finalize, separate, and bridge the gap

At Month 2, the retirement is locked and the focus shifts to logistics. Complete any handover documentation your position requires; submit your final timesheet; confirm with HR that your retirement package has been received and forwarded to OPM with a tracking number; and notify your supervisor in writing. Federal agencies need time to backfill; many request 60–90 days notice, but there is no statutory minimum. At Month 2 also finalize any open-season plan changes (Open Season runs mid-November to mid-December) and update your address with HR so your final W-2, SF 50, and OPM retirement packet reach you.

At Month 1, finish clearance debriefings (security-cleared employees must surrender badges and equipment), submit outstanding travel reimbursement vouchers, return property (laptops, phones, keys, parking permits), and confirm your annual leave balance for the lump-sum payout under 5 USC § 6304(d) (capped at 30 days for most employees, 60+ for SES). Set up Services Online access — your OPM retirement account is accessed through Services Online, not your agency HR system; you will receive a CSA claim number once OPM begins processing. File for Social Security 3–4 months before your claiming date if applicable.

Plan for the annuity gap — the 30–90 day window between separation and first annuity payment. Have cash reserves; TSP withdrawals and final paycheck lump sums typically arrive within weeks of separation. After separation, OPM mails a Welcome Letter with your claim number, initial annuity computation, and any deposit requests. Review it carefully — errors in OPM's initial computation are common and far easier to correct within the first 30 days than years later.

Common mistakes and how to avoid them

The Federal Employees Retirement System Act was designed to be navigable without an attorney, but most retirees make at least one of these mistakes:

• Leaving military time unbought. The deposit seems small but the annuity boost is large — typically a 5–10× return over a retiree's lifetime.
• No beneficiary updates after divorce/remarriage. TSP-3, SF 3102, and FEGLI 2823 must all be re-filed. Federal law will pay whoever is on the form.
• Delaying the SF 3107. Submitting weeks before retirement guarantees a long annuity gap. Submit 60–90 days out.
• Self-only FEHB at retirement — surviving spouse loses FEHB. This single mistake has caused more financial hardship than any other retirement-planning error in the federal workforce.
• Choosing no survivor benefit — sometimes appropriate (spouse has own substantial federal benefits), but often chosen to maximize monthly annuity without modeling the survivor scenario.
• Forgetting the MRA+10 age reduction — retiring at MRA (57) with less than 30 years means a 5% per year reduction.
• Not tracking the FERS Supplement end. The Supplement stops at age 62 — many retirees budget as if it continues.

Takeaways

Federal retirement is a 12-month project, not a one-day decision. The SCD verification, military deposit, FEHB 5-year rule, and beneficiary forms all have long lead times and cannot be retroactively fixed. The SF 3107 application must reach OPM with enough runway to avoid a long annuity gap. The survivor benefit election and FEHB enrollment level at retirement are irreversible. Use the FERS Federal Pension Estimator calculator early and often — running scenarios with different retirement dates, survivor elections, and TSP withdrawal rates is the only way to see how the pieces interact. Treat the 12-month countdown as a project with deadlines: assign each item a date, follow up weekly, and document every submission. The annuity you receive for the next 30 years depends on what you do in these 12 months.
