In this section, you'll find information about FERS eligibility, annuity estimates, military service credit, TSP contributions, and the retirement application process.
Am I eligible to retire? What is my Minimum Retirement Age (MRA)?
Under FERS (the Federal Employees Retirement System) you can retire on an immediate, unreduced annuity at MRA with 30 years, age 60 with 20 years, or age 62 with 5 years. Your MRA is 55-57 depending on birth year. MRA+10 allows retirement with 10-29 years but with a permanent reduction unless postponed.

Can I get an annuity estimate for a specific retirement date?
Run estimates yourself anytime in your agency's retirement system (e.g., GRB, FedHR Nav Platform). For a counselor-verified estimate (recommended 1-2 years out), submit a retirement services ticket with your target date and any military service.

How do I buy back my military service time?
Request estimated earnings from your branch's pay center via form RI 20-97 with your DD-214, submit to HR for a deposit calculation (generally 3% of military basic pay plus interest for FERS), then pay via payroll deduction or lump sum before retiring.

What happens to my unused sick leave when I retire?
Unused sick leave is added to your service time for the annuity computation (not eligibility). FERS retirees get full credit; roughly 174 hours equals one month of additional service credit.

How do I change my TSP (Thrift Savings Plan) contribution amount or percentage?
How much will my military deposit cost and is it worth it?
Generally, 3% of military basic pay plus accrued interest starting a few years after hire—so it costs more the longer you wait. Usually worthwhile since it counts toward eligibility and computation, but military retired pay generally must be waived for it to count.

How do I verify my Service Computation Date is correct?
Your SCD (Leave) appears in Block 31 of your SF-50; note it can differ from your retirement SCD. Pull SF-50s from eOPF and compare to your service history; open a Records ticket if something's off.
Resources: eOPF
How do I request copies of my SF-50s to document federal service?
Current employees can log into eOPF and download them directly. If you can't access eOPF or documents are missing, submit a Records request.

How do I take a TSP loan?
Am I eligible for TSP catch-up contributions?
Can I roll over an old 401(k) into my TSP?
What survivor benefit options do I have at retirement?
FERS lets you elect a full survivor annuity (50%, costing 10% of your annuity), partial (25%, costing 5%), or none—electing less than full for a spouse requires notarized consent. This election also determines if your spouse can keep FEHB after your death.

Am I eligible for the FERS Special Retirement Supplement?
The supplement approximates Social Security earned as a FERS employee, paid to those retiring on an immediate, unreduced annuity before age 62 (e.g., MRA+30 or 60+20, not MRA+10). It ends at 62 and is subject to an earnings test.

I retired months ago - why is my OPM retirement package still in interim pay?
OPM pays interim annuity payments while it finalizes your case, then pays any accrued difference retroactively. Processing time varies with case complexity. Check status at OPM Services Online.

How do I apply for a refund of retirement contributions if I leave federal service?
Submit form SF-3106 to OPM after being separated at least 31 days. Taking a refund voids your right to an annuity for that service unless later redeposited with interest.

How does part-time service affect my annuity calculation?
Part-time service counts fully toward eligibility, but the annuity is prorated based on hours worked vs. full-time hours over your career. Your high-3 salary uses full-time equivalent rates.

Does temporary or seasonal service count toward retirement?
It depends on timing and whether deductions were taken. Non-deduction service before 1989 can be credited by paying a deposit; most post-1988 temporary service is not creditable for FERS.

How do I designate beneficiaries for my TSP and FERS contributions?
TSP beneficiaries are designated online at tsp.gov (paper TSP-3 in limited cases). For FERS lump-sum contributions use form SF-3102. Without a designation beneficiary, funds follow the statutory order of precedence.

What forms make up the retirement application package and what's the timeline for submitting it?
The retirement application is built around Standard Form 3107 (FERS) or Standard Form 2801 (CSRS), now submitted through OPM's Online Retirement Application (ORA), which walks you through benefit elections like survivor benefits, health and life insurance continuation, tax withholding, and direct deposit. ORA prefills key records such as your service history and high-3 salary, though TSP and Social Security benefits require separate applications. OPM recommends starting the process with your HR office at least 60 days before your retirement date — and if your package is complete by your separation date, OPM has committed to paying eligible retirees within seven days of retirement.

I'm a FERS employee planning to retire at the end of next year. When should I submit my retirement application, and what steps should I take now to make sure my annuity payments aren't delayed?
OPM recommends submitting your completed retirement application to your agency's HR office at least 60 days before your planned retirement date. In the meantime, verify that all your federal service is documented in your personnel folder and request an annuity estimate from HR so you can plan for the interim payment period. Also confirm your eligibility to continue health and life insurance coverage into retirement — generally you must have been enrolled for five years immediately before retiring. Finally, consider retiring at the end of the month so your annuity begins the first day of the following month.

I'm separating - what do I need to do before my last day?
Submit your resignation/retirement in writing, complete the agency clearance process, and review the exit checklist covering lump-sum annual leave, FEHB/FEGLI continuation options, TSP, and final LES/W-2 address.
