CSRS Retirement Planning Timeline: What to Do 12 Months, 6 Months, and 90 Days Out

Retiring under CSRS takes longer to prepare than most employees expect — not because the paperwork is overwhelming, but because the dependencies have long lead times. A military deposit calculation can take 6 months. An unresolved service discrepancy from 1982 can add another 3 months of back-and-forth with HR. If you discover these issues at the 90-day mark when you're trying to submit your ORA application, you're either delaying your retirement date or accepting a permanently reduced annuity.

Here's the timeline that gives each step enough runway.

12 to 24 Months Before: The Audit Window

Request a service history audit from your HR office. This generates your SF 2801-1 (Certified Summary of Federal Service) — the master document that lists every period of creditable service, every break, and every deposit obligation. Review it line by line against your own records.

This is where you catch problems that take months to fix:

• Temporary service from the late 1970s or early 1980s that was never transferred between agencies
• Military service that appears credited but has no deposit record
• A break in service coded at 400 days when it was actually 350 (the difference between CSRS and CSRS Offset classification)
• Part-time service periods with incorrect schedule fractions

Initiate any civilian deposits or redeposits. Submit SF 2803 through your HR office. OPM calculates the amount owed — principal plus compound interest — and sends the bill back. Processing takes 6 to 12 months. Interest compounds on December 31 each year, so starting in January versus October can save you a full year of interest charges.

Start the military deposit process. Request Form RI 20-97 from your military branch's finance center and gather your DD Form 214. The military finance center verifies your earnings history, your HR office calculates the deposit, and you pay through your agency's payroll office. Every step has its own processing time.

12 Months Before: Estimates and Elections

Get a formal annuity estimate. Your benefits specialist runs the computation using your verified service record and projected High-3 salary. If you're CSRS Offset, request two estimates: pre-62 (full annuity) and post-62 (with the offset reduction). The difference is the income gap you need to plan around.

Identify your High-3 window. For most CSRS employees retiring after a full career, the High-3 is the last three years. But check — an earlier 36-month window can produce a higher average if your pay history includes a demotion, transfer, or reduction. A few hundred dollars in High-3 difference multiplied by 2% per year of service beyond 10 years adds up.

Begin the survivor annuity analysis. Run the cost of the full survivor election (55% to your spouse, approximately 10% reduction to your annuity) against alternatives. If you're leaning toward anything less than full coverage, your spouse needs time to understand the implications and sign the notarized consent form (SF 2801-2).

6 Months Before: Benefits Coordination

Verify your FEHB enrollment continuity. You need 5 years of continuous FEHB enrollment (or continuous coverage since your first appointment, if less than 5 years) to carry health insurance into retirement. Check your enrollment history — a gap, even a short one during a break in service, can disqualify you.

Evaluate FEGLI continuation options. Compare the cost of the 75%, 50%, and No Reduction options for Basic coverage against your actual insurance needs. The 75% reduction makes Basic coverage free after age 65 but reduces it to 25% of the original face value. If you need lifetime coverage at the full amount, the No Reduction option costs $2.25 per $1,000 of coverage per month after age 65 — do the math on whether that's competitive with private term life.

Set up your ORA digital credentials. Register on OPM's Online Retirement Application platform. Log in, verify that your pre-populated payroll data is accurate, and test the document upload function. Don't wait until the 90-day submission window to discover a data error in the system.

Research your Social Security position (Offset employees). Create or verify your my Social Security account at ssa.gov. Pull your estimated benefits at age 62, Full Retirement Age, and 70. Model the OPM offset reduction against each claiming scenario to determine your optimal filing strategy.

90 Days Before: Application Submission

Submit your retirement application through ORA. Complete every section, upload all supporting documents, and submit. Your HR office begins its review and certification process (averaging 60 days). The earlier you submit, the more runway HR has before your separation date.

Confirm your separation date. The optimal date is the last day of a pay period or the last day of a month. Here's why:

• Federal pay runs in biweekly pay periods. Retiring on the last day of a pay period means a clean final paycheck with no partial-period complications.
• Your voluntary CSRS annuity generally commences on the first day of the month after separation. A three-day rule can make it commence the day after separation (or pay ceases) if you were in pay status for three days or fewer in the retirement month.
• A December 31 separation generally produces a January 1 commencing date; the first COLA is prorated based on that commencing date. HR can model specific separation dates.

Your HR office can confirm the specific optimal dates for the calendar year.

30 Days Before: Cash Bridge and Logistics

Fund your cash bridge. Transfer 3 to 6 months of living expenses into a liquid savings account. The gap between your last paycheck and OPM's first interim payment averages 111 to 120 days, during which you may have no annuity or interim retirement payments.

Set up BENEFEDS direct billing. Your dental and vision premiums (through BENEFEDS) cannot be deducted from OPM interim payments. Arrange direct-billing before your separation to avoid coverage cancellation.

Adjust your TSP elections. If you're planning post-retirement TSP withdrawals, verify that your distribution method (monthly payments, single withdrawal, or combination) is set up in your TSP account. Note that TSP withdrawals cannot begin until your agency reports your separation to the TSP — a process that can take 30 to 60 days.

Collect your documentation. Ensure you have personal copies of:

• Your annuity estimate (from the 12-month mark)
• The signed and notarized SF 2801-2 (if applicable)
• Your DD Form 214 and RI 20-97 military deposit confirmation
• Your FEHB enrollment verification
• Your FEGLI continuation election (SF 2818)

After Your Last Day

Monitor the processing pipeline. Your HR office reviews and certifies the service record (about 60 days), then the payroll provider processes final pay and transmits the package to OPM (another 51 days). When OPM receives the package, you'll get a CSA number — your permanent retirement account identifier.

Verify your annual leave payout. The lump-sum payment for unused annual leave is calculated at the basic-pay rate in effect at separation, with applicable pay adjustments during the projected leave period. It's taxable income in the year of separation, so factor it into your tax planning.

Watch for the first interim payment. OPM targets disbursement within 7 days of receiving your certified package. If you don't see a payment within two weeks of getting your CSA number, contact OPM's Retirement Information Office.
