Firefighter Disability Retirement Under FERS: Eligibility, Benefits, and How to Apply

When Injury Ends Your Line Career Before You Reach 20 Years

Federal firefighters who suffer an injury or develop a medical condition that prevents them from performing the rigorous duties of their position face a specific retirement question: what happens if you cannot stay in a 6(c) covered role but have not yet hit the 20-year or 25-year service threshold for a voluntary special provision retirement?

FERS disability retirement under 5 U.S.C. § 8451 exists for this scenario. It is a separate track from OWCP wage-loss compensation, with different eligibility rules, different benefit calculations, and different long-term implications.

Eligibility Requirements

To qualify for FERS disability retirement, you must meet all of these:

• At least 18 months of creditable civilian service under FERS
• A medical condition expected to last at least one year that prevents you from performing the essential duties of your current position (or any vacant position at the same grade or pay level, within the same agency and commuting area, to which you could be reassigned)
• The agency must confirm that it cannot accommodate you in your current position or reassign you to another position you are qualified for
• You must apply for Social Security disability benefits as part of the FERS disability application process

You do not need to be totally disabled. The standard is that you cannot perform the duties of your specific position — for firefighters, that means the rigorous physical requirements of fire suppression. A firefighter who can still work a desk job but cannot meet the physical standards for line duty may qualify.

How the Benefit Is Calculated

FERS disability retirement pays differently depending on your age:

Under age 62: If you are not eligible for an immediate voluntary FERS annuity, during the first 12 months you receive 60% of your high-3 average salary minus 100% of any Social Security disability benefit you are entitled to. After the first year, the benefit is 40% of your high-3 minus 60% of your Social Security disability benefit. If your earned annuity is higher than either calculation, OPM pays the earned annuity.

At age 62: OPM recomputes your annuity using service as if you had continued working until age 62, including time on the disability annuity rolls. Actual service in an enhanced firefighter position keeps the 1.7% rate; other service uses the standard 1.0% rate, or 1.1% if you have at least 20 years of service at age 62.

Disability Retirement vs. OWCP: The Key Differences

These are two separate programs that address overlapping situations. In most cases, you must elect either the FERS disability benefit or OWCP benefits; OPM allows an OWCP scheduled award to be paid with FERS benefits.

OWCP (FECA) pays 66.67% to 75% of basic pay, tax-free, for as long as the injury-related disability continues. It requires that the injury or illness be work-related. It does not require a minimum service period.

FERS disability retirement pays 60%/40% of high-3 (minus Social Security offsets), is taxable, and requires 18 months of service. It does not require the condition to be work-related — an off-duty car accident that leaves you unable to perform suppression duties qualifies.

For most firefighters with work-related injuries, OWCP pays more in the short term. OWCP benefits can change if your work capacity or eligibility changes. A FERS disability annuity may end before age 62 if OPM finds that you have medically recovered, restored earning capacity, or returned to an equivalent federal position; otherwise, OPM recomputes it at age 62 as a regular retirement annuity.

The First Responder Fair RETIRE Act (Public Law 117-225) can preserve enhanced coverage for a firefighter reappointed to a non-covered position after a qualifying duty injury or illness. The injury or illness must occur on or after December 9, 2024, directly result from duties in the covered position, permanently prevent useful and efficient service in that position without precluding continued federal service, and be certified by the employing agency. The employee must not already be eligible for immediate retirement or mandatory separation when injured, and must be reappointed without a break in service of more than three days to the same agency or an agency that regularly appoints to related supervisory or administrative positions. OPM published proposed regulations in July 2026. For eligible firefighters, staying in federal service in a non-covered role may be a better long-term outcome than disability retirement.

How to Apply

If you are still employed, contact your servicing HR office to start the application through OPM's Online Retirement Application (ORA); former employees apply to OPM through ORA. SF 3112 is the Documentation in Support of Disability Retirement Application, not the application itself. The package requires medical documentation supporting your claim and agency certification that it cannot accommodate or reassign you. If you have separated, OPM generally must receive your application within one year of separation.

OPM reviews the application and makes the final determination. Processing typically takes several months, and you can remain on OWCP wage-loss benefits during the review period.
