How to Apply for FERS Disability Retirement
Before You Touch a Single Form
The application itself is the last step, not the first. Before you fill out SF 3107 or any part of the SF 3112 series, three things need to happen — and if they don't, OPM will send your package back incomplete.
Request reasonable accommodation. File a formal written request with your agency's Reasonable Accommodation Coordinator or HR office. The agency must engage in an interactive process to explore whether modifying your duties, equipment, schedule, or work environment would let you keep performing your job. Document everything. Informal "light duty" arrangements don't count — OPM needs a paper trail showing formal accommodation was attempted and either failed or was denied.
Wait out the reassignment search. If accommodation in your current position isn't feasible, HR must search for a vacant position at the same grade, pay level, and commuting area where you could perform the essential functions. If they find one and you decline it, you lose eligibility. If nothing suitable exists, HR certifies that on SF 3112D.
Apply for SSDI. Every FERS disability applicant under age 62 must file for Social Security Disability Insurance. You need proof of filing — an SSA-16 receipt or application notice — before OPM will process your retirement claim. Apply online at ssa.gov or at your local SSA office. OPM doesn't wait for SSA's decision, and an SSDI denial won't kill your FERS application (the two programs use completely different legal standards).
The Forms You Need
Your application package has two main components:
SF 3107: Application for Immediate Retirement
This is the general retirement application that every federal retiree fills out — voluntary or disability. It captures:
- Your personal information and service history
- Survivor benefit elections (if you're married, your spouse must sign SF 3107-2 to waive or reduce the survivor annuity)
- FEGLI life insurance continuation choices
- Direct deposit information
SF 3112 Series: Disability-Specific Forms
Five forms, each completed by a different person:
SF 3112A — Applicant's Statement of Disability. This is your narrative. Describe your medical condition, when symptoms began, how they affect specific duties listed in your position description, what accommodations you've tried, and why you can no longer perform useful and efficient service. Be concrete — "I cannot stand for more than 15 minutes, which prevents me from conducting the 2-hour field inspections listed in my PD" is far stronger than "my back hurts and I can't do my job."
SF 3112B — Supervisor's Statement. Your immediate supervisor fills this out. It covers your performance ratings, attendance patterns, any documented performance deficiencies, and what accommodations the agency attempted.
SF 3112C — Physician's Statement. Your treating doctor provides the clinical narrative — diagnosis, prognosis, treatment history, and a detailed explanation of how your condition limits your ability to perform specific job functions. This is the single most important document in your package. A one-paragraph note saying "patient is disabled" will get denied. OPM needs a clinical nexus: a documented link between your medical findings and the physical or cognitive demands in your position description.
SF 3112D — Agency Certification. HR certifies the results of the accommodation and reassignment process.
SF 3112E — Disability Retirement Application Checklist. The agency's HR specialist uses this to confirm every piece of the package is assembled before submission.
Where to Submit
If you're still employed (or separated 31 days or less): Submit the entire package to your agency's HR office. Since July 2026, agencies process and submit retirement files electronically through OPM's Online Retirement Application (ORA) portal.
If you've been separated more than 31 days: Submit SF 3107 and SF 3112A directly to OPM's Retirement Operations Center in Boyers, Pennsylvania. Coordinate with your former supervisor and HR to have them complete SF 3112B, 3112D, and 3112E and send those directly to OPM as well.

The One-Year Deadline
If you've already separated from federal service, your complete (or protective incomplete) application must reach OPM within one year of your separation date. This deadline is statutory under 5 U.S.C. § 8453 — OPM has no authority to grant extensions.
If you're running up against the deadline and can't get all forms completed, submit what you have. A protective filing with just SF 3107 and SF 3112A preserves your timeline. You can submit the remaining documentation afterward.
What Happens After Submission
OPM logs your application and issues a CSA claim number. If you've separated and aren't receiving regular pay, you may be placed in interim pay status — partial annuity payments while OPM reviews your case. As of mid-2026, OPM's average processing time is approximately 108 days for retirement cases generally, though disability claims with complex medical records can take longer.
OPM's Disability Division reviews your medical and administrative evidence. They may contact you or your agency for additional information. If approved, you're transitioned to the disability retirement roll with retroactive back pay covering any gap between your last paycheck and the annuity start date.
If denied, you have 30 days to request reconsideration. If OPM upholds the denial, you can appeal to the Merit Systems Protection Board within 30 days.
Common Filing Mistakes
Relying on diagnosis alone. OPM doesn't approve applications because you have a medical condition. They approve when the evidence shows that condition prevents you from doing your specific job. Every document in your package should connect clinical findings to position description duties.
Skipping the accommodation paper trail. Even if your supervisor informally agreed to reduce your workload, OPM needs formal documentation. No paper trail means no evidence that accommodation was attempted and exhausted.
Withdrawing your SSDI application. If you withdraw your SSDI filing for any reason, OPM is legally required to dismiss your FERS disability retirement application. File for SSDI and leave it pending, regardless of whether you think you'll qualify.
Missing the one-year deadline. If you've separated, the clock is running. Don't wait until your former agency completes its paperwork — file a protective application directly with OPM.
The FERS Disability Retirement Guide includes document assembly trackers, physician collaboration templates, and a protective filing checklist designed to prevent these mistakes before they happen.
