FERS Disability Retirement While Still Working: Active Employee Filing Guide

Filing While You Are Still on the Federal Payroll

You do not need to wait until you are separated from service to start a FERS disability retirement application. In fact, filing while you are still an active employee is strategically stronger than waiting — you have direct access to your supervisor for SF 3112B, your agency HR can initiate the reassignment search, and the entire package can be submitted electronically through the Online Retirement Application (ORA) portal by your agency's payroll office.

The basic sequence for an active employee filing:

1. Request reasonable accommodation through your agency's EEO or HR office and document the interactive process
2. If accommodation fails, HR conducts the formal reassignment search within your agency, grade, and commuting area
3. Compile your application: SF 3107, SF 3112A through 3112E, your physician's clinical narrative, and proof of SSDI filing
4. Submit the complete package through your agency HR, which forwards it electronically to OPM

Your agency continues paying you until your effective retirement date. If OPM has not yet decided your claim when you separate, you transition to interim pay status until adjudication is complete.

The Critical Difference: Active vs. Post-Separation Filing

The one-year filing deadline under 5 U.S.C. § 8453 only applies to employees who have already separated from service. If you are still employed, there is no external deadline — but there are practical ones. A progressive medical condition that is degrading your attendance, performance, or conduct may lead your agency to initiate a medical separation or adverse action. If that happens and you have not yet filed, you start the one-year clock from your separation date.

For employees who have been separated for more than 31 days, the filing process changes substantially. Your former agency may no longer have your personnel records readily available. You must submit SF 3107 and SF 3112A directly to OPM's Retirement Operations Center in Boyers, Pennsylvania, while coordinating with your former supervisor and HR to send their portions (SF 3112B, D, and E) separately to OPM.

Protective Filing: Securing Your Timeline

If you have been separated and the one-year deadline is approaching but your application package is incomplete — your physician has not finished the clinical narrative, or your former supervisor has not returned SF 3112B — you can submit a protective filing.

A protective filing means sending SF 3107 and SF 3112A directly to OPM before the deadline expires, even though the supporting forms are not yet complete. OPM accepts incomplete applications for the specific purpose of preserving your filing date. Once the application is logged, OPM sends requests for the missing documentation to you and your former agency.

The key requirements for a valid protective filing:

• SF 3107 must be completed and signed with your personal information, service history, and survivor benefit elections
• SF 3112A must include your narrative statement of disability — even a preliminary version that describes your condition and its impact on your duties
• Proof of SSDI filing should be included if available (SSA-16 receipt or application confirmation)
• Submit via certified mail, return receipt requested, so you have proof of the date OPM received it

The five-day mailing presumption under OPM regulations means that if you mail your application and OPM receives it within five days of the postmark, the postmark date counts as the receipt date. But certified mail with tracking eliminates any ambiguity.

Can You File for FERS Disability After Termination?

Yes. An employee who is terminated, removed for cause, or medically separated retains the right to file for FERS disability retirement as long as the application reaches OPM within one year of the separation date. The reason for separation does not disqualify you from disability retirement — what matters is whether you can demonstrate that a medical condition prevented useful and efficient service in your position of record before or at the time of separation.

Employees who are terminated while on extended Leave Without Pay (LWOP) face the same deadline. The clock starts from the effective date on your SF-50 separation action, not from your last day physically at work.

What Not to Do

Two actions can permanently derail a pending or potential FERS disability claim:

Do not submit a standard voluntary retirement application while a disability claim is pending. OPM treats a standard retirement application as a voluntary withdrawal of the disability claim. If you qualify for both, file the disability application and let OPM determine which calculation is more favorable.

Do not withdraw your SSDI application. The statutory requirement to apply for SSDI is non-negotiable for FERS disability applicants under age 62. If you withdraw the SSDI application for any reason, OPM must dismiss your FERS disability retirement claim.

The FERS Disability Retirement Guide walks through both active-employee and post-separation filing paths with a deadline tracker and protective filing checklist.
