The certified summary of federal service is the official record your agency puts together to verify every period of your federal career before you retire, and it becomes the primary evidence OPM uses to calculate your annuity. Your monthly benefit under CSRS or FERS depends directly on the length of creditable service shown on this form and on your highest three years of basic pay, so an error here shrinks your annuity or delays your first check. The agency drafts the form, but you are the one who has to catch mistakes before you sign.
What the Summary Records
The certified summary captures every period of creditable service used to determine both your eligibility to retire and the size of your annuity. That includes all civilian federal employment with beginning and ending dates, agency names, pay rates, and the type of appointment — career, career-conditional, term, or temporary.1Office of the Law Revision Counsel. 5 USC 8332 – Creditable Service It also notes whether retirement deductions were withheld from your pay during each period, because service without deductions may require a deposit before it counts.
Military service appears on the summary only if you have completed a military service deposit, the “buyback.” Active duty under honorable conditions is eligible, but the deposit must be paid in full before your retirement date for the time to count.2U.S. Office of Personnel Management. Federal Retirement
Part-time service is recorded with the exact number of hours worked so that prorated credit can be calculated. Your unused sick leave balance at retirement is also included and adds months of service credit to your annuity computation. Under CSRS, unused sick leave converts using a 2,087-hour work year, with eight hours of unused sick leave equal to one day of credit.3U.S. Office of Personnel Management. Credit for Unused Sick Leave Under the Civil Service Retirement System FERS employees receive the same benefit. One boundary to keep in mind: sick leave credit only increases the service used to compute your annuity, it cannot help you meet the minimum years needed to qualify for retirement in the first place.
Who Fills Out the Form
A common misconception is that the employee drafts the summary. In practice, your agency’s human resources office completes the form from official records and then sends it to you for review and signature.4U.S. Office of Personnel Management. Applying for Immediate Retirement Under the Civil Service Retirement System CSRS employees use Standard Form 2801-1 and FERS employees use Standard Form 3107-1.5U.S. Office of Personnel Management. Standard Form 2801 – Application for Immediate Retirement Your job is to examine every line, flag anything that looks wrong, and sign only your section. Do not sign where the certifying official signs.
After you sign, the certifying official compares the entries against your electronic Official Personnel Folder, individual SF-50 personnel action forms, and payroll archives. If something does not line up, the agency has to resolve it before signing off. That signature is the agency’s formal attestation that the service history is accurate, and the certified summary then travels with the rest of your retirement package to OPM.
How to Review Your Summary Line by Line
Read the form as if every line is worth money, because it is. Agencies sometimes miss short stints at other agencies or temporary appointments from decades ago, and if you sign off without catching an omission, correcting it after the package reaches OPM can take months.
Work through the summary looking for the following:
- Every appointment you held, in date order, with no gaps you cannot explain.
- The correct appointment type and retirement system code for each period.
- Accurate pay rates, especially for the three-year window that will produce your high-three average.
- Whether retirement deductions were withheld, and whether any required deposit has been paid.
- Military service, listed only if your buyback is complete.
- Part-time periods showing the correct hours.
- Your sick leave balance as of separation.
Leave Without Pay gets special treatment. Up to six months of LWOP in a given calendar year counts as creditable service without any additional payment. Any LWOP beyond six months in the same calendar year is not creditable, and unlike other gaps in deductions, you cannot make a deposit to recover it. Extended unpaid leave can permanently reduce your annuity, so confirm how the agency has coded these periods.
Deposits That Must Be Paid Before You Retire
Several types of service will only appear on your certified summary if you pay into the retirement fund first. Miss these deadlines and the uncredited service disappears from your annuity calculation.
Military Service Deposit
Under FERS, the deposit for military service equals 3 percent of your basic military pay for the period claimed, plus interest.6eCFR. 5 CFR 842.307 – Deposits for Military Service Interest begins accruing two years after you first become covered by FERS and compounds annually until you pay the deposit in full or your annuity starts, whichever comes first. For 2026, the applicable interest rate is 4.25 percent. The deposit must be completed before your retirement date.7Defense Finance and Accounting Service. Military Service Buy Back If you wait until the last year before retirement, the paperwork and payment schedule can easily run past your planned separation date.
Pre-1989 Non-Deduction Service
Federal civilian service performed before January 1, 1989 during which no retirement deductions were withheld can be credited under FERS only if you make a deposit. The amount is generally 1.3 percent of the salary you earned during that period, plus interest compounded annually from the midpoint of the service.8U.S. Office of Personnel Management. Creditable Service Skip the payment and the service will not count toward eligibility or your benefit amount.
Redeposits for Refunded Contributions
If you left federal service at some point and received a refund of your retirement contributions, you can redeposit that amount plus interest to restore the service credit. The same 4.25 percent interest rate for 2026 applies. Failing to redeposit means the refunded period is either excluded entirely or credited at a reduced annuity rate, depending on your retirement system and when the refund was taken.
Documents to Gather Before You Review
Even though your agency drafts the summary, assemble your own records well ahead of time so you can verify what the agency produces. Reviewing your electronic Official Personnel Folder a year or two before retirement is one of the simplest ways to catch missing records early. The eOPF gives you online access to your personnel forms and notifies you by email when new documents are added.9U.S. Office of Personnel Management. What Is the Electronic Official Personnel Folder (eOPF)?
- DD Form 214 for each period of military service you want credited.10National Aeronautics and Space Administration. How to Complete Retirement Forms
- SF-50 Notification of Personnel Action forms documenting every appointment, promotion, reassignment, and pay change throughout your career.
- Payroll records or earnings statements confirming when retirement deductions were or were not withheld.
- Receipts for any military service deposit or non-deduction service deposit you have already paid. Without proof, disputes over completion are much harder to resolve.
When to Start
Your agency needs about 60 days to process the retirement application before forwarding it to OPM, roughly 30 days for the human resources office and 30 days for the payroll office, and some agencies require more.11U.S. Office of Personnel Management. When Should I Complete My Retirement Application? If you have military deposits to complete, records to track down, or periods of non-deduction service to resolve, starting 12 to 18 months before your planned retirement date is not excessive. Deposits in particular must be paid in full before your last day, and the payment process itself can take several months.
What Happens After You Sign
Once OPM receives your complete package, current processing times for immediate retirements average about 71 days as of early 2026.12U.S. Office of Personnel Management. Retirement Processing Times Cases involving service at multiple agencies or unresolved deposit questions are the ones most likely to run longer.
You will not go without income during that stretch. OPM issues interim annuity payments, typically 60 to 80 percent of your estimated net annuity, beginning within about eight days of receiving your completed package.13U.S. Office of Personnel Management. Retirement Quick Guide Once OPM finalizes your annuity, you receive a lump-sum adjustment for the difference. Plan your finances around the interim figure, not the full estimated annuity.
OPM adjudicators independently review the certified summary, recalculate your creditable service and your high-three average salary, and arrive at your exact monthly annuity. The high-three is based on your highest basic pay over any three consecutive years of civilian service, weighted by how long you received each pay rate. Basic pay includes your base salary and locality pay but excludes overtime, bonuses, and cash awards. OPM can accept the certified service credit, adjust it, or deny credit for periods that do not meet statutory requirements.14Office of the Law Revision Counsel. 5 USC 8411 – Creditable Service The certified summary then remains the primary evidence supporting your annuity for the rest of your life as a retiree.
Recovering Missing Employment Records
Gaps in service history are common, especially for employees who worked at multiple agencies or held temporary positions decades ago. If your eOPF is missing records, start by contacting the human resources office of the agency where you worked during the missing period. Former agencies may still hold archived payroll data or SF-50s.
For military records, you can request verification from the National Personnel Records Center in St. Louis by submitting a Standard Form 180, either online through eVetRecs or by mail.15National Archives. Access to Official Military Personnel Files (OMPF) Provide as much identifying information as possible: full name used during service, service number, branch, dates of service, and Social Security number. Records affected by the 1973 fire at the NPRC may require reconstruction from alternate sources, which takes additional time. The NPRC also maintains Official Personnel Folders of former federal civilian employees whose service ended after 1951.16National Archives. National Personnel Records Center (NPRC) Reconstruction requests can take months, so start early rather than waiting until your retirement application is already in motion.
