Disability Retirement for Federal Employees: Filing and Benefits

Federal disability retirement is a monthly annuity paid by the Office of Personnel Management to civil servants whose medical condition prevents them from performing the duties of their job. It covers employees under both the Federal Employees Retirement System (FERS) and the older Civil Service Retirement System (CSRS). FERS employees qualify with 18 months of creditable civilian service; CSRS employees need five years.¹² The bar for approval is lower than most applicants assume: you don’t have to prove you can’t work at all, only that you can’t perform at least one essential function of your specific position, and that your agency can’t accommodate or reassign you.

Who Qualifies

Two things have to be true at once. You need the minimum service, and you need a qualifying medical condition.

The service thresholds are 18 months of creditable civilian service for FERS and five years for CSRS.¹² The condition itself must be expected to last at least one year.³

OPM applies an occupational standard, not a total-disability standard. You qualify if a disease or injury prevents you from rendering useful and efficient service in your current position, meaning you can’t perform at least one essential function of the job or your attendance has become too unreliable to meet the position’s demands.² The condition doesn’t have to be work-related, and a pre-existing condition that worsens during federal service counts.

Your agency plays a gatekeeping role. Before OPM will approve a claim, the agency has to certify that it tried to accommodate you in your current role and that it looked for a vacant position at the same grade or pay level in your commuting area for which you’re qualified.⁴ Temporary light duty or modified duty does not count as a reasonable accommodation for this purpose.³

What You File

The core of the application is the SF 3112 package, which bundles your statement of disability (SF 3112A), your supervisor’s statement (SF 3112B), your physician’s statement (SF 3112C), the agency certification (SF 3112D), and a checklist (SF 3112E).⁵⁶⁷

FERS employees have one extra requirement that CSRS employees do not. You must apply for Social Security Disability Insurance with the Social Security Administration and give OPM proof that you did so.⁴ Whether the SSA approves or denies the SSDI claim doesn’t affect OPM’s decision, but skipping the SSDI application or withdrawing it will cause OPM to dismiss your disability retirement application outright.

The physician’s statement is where most weak applications fail. A general letter saying you “can’t work” isn’t enough. Your doctor needs to tie clinical findings and diagnostic results to the specific duties in your position description, describe your functional limitations concretely, and state that the condition is expected to last at least a year. If your job requires standing for extended periods, the documentation should explain why your condition prevents that specific activity rather than describing your health in general terms.

Where and When to Submit

If you’re still on your agency’s rolls, the entire package goes to your Human Resources office, which adds agency records and forwards everything to OPM.⁴ If you’ve been separated from federal service for more than 31 days, send it directly to OPM.

The deadline is firm. Your application must reach OPM within one year of your separation date.⁸ The only waiver available is for applicants who were mentally incompetent to file during that window. Not knowing the rule, or simply running late, does not qualify.⁴

When OPM receives your application it assigns a seven-digit civil service claim number preceded by “CSA,” which you’ll use in every future communication about your annuity.⁹ OPM’s published processing time for approved immediate retirements, including disability cases, is about 71 days after receipt.¹⁰ That figure reflects processing after OPM has already made the medical determination; complex or disputed cases can take considerably longer to reach a decision.

What It Pays

FERS

The FERS disability annuity is tiered and uses your high-3 average salary, which is the highest average basic pay over any three consecutive years of your federal career.¹¹

For the first 12 months, you receive 60% of your high-3, reduced by 100% of any SSDI benefit you receive for the same period.
From month 13 until age 62, the annuity drops to 40% of your high-3, reduced by 60% of any SSDI benefit.
At age 62, OPM recalculates your benefit as an earned retirement annuity, crediting the disability years as though they were years of actual service.

The floor matters: after the SSDI reduction, your disability annuity can never fall below what the standard FERS retirement formula would pay based on your actual years of service.¹¹

CSRS

CSRS uses the standard CSRS annuity formula but with a guaranteed minimum, so employees with shorter careers still receive a meaningful benefit.² Because CSRS employees generally don’t pay into Social Security, there is no SSDI offset. If you have substantial service, you receive whichever is higher: the disability minimum or your earned annuity under the regular formula.

Cost-of-Living Adjustments

CSRS disability retirees get the full CSRS COLA every year. FERS disability retirees get an exception to the usual FERS rule that no COLA is paid before age 62: they receive annual COLAs at any age. For 2026, the CSRS COLA is 2.8% and the FERS COLA is 2.0%.¹² Adjustments are applied in December, and the adjusted payment arrives in January.

Keeping Health and Life Insurance

FEHB coverage carries into disability retirement only if you’ve been continuously enrolled for at least the five years immediately before you retire; if your entire federal career was shorter than five years, being covered for all of it usually satisfies the rule.¹³ The government keeps paying its share of the premium after you retire. If you were covered under a spouse’s plan and never enrolled in FEHB yourself, you can’t sign up at retirement and bring the coverage with you.

The same five-year rule applies to Basic and Optional FEGLI. You have to be enrolled at retirement and have been covered for the five years before it (or for your full period of service if shorter).¹⁴ OPM cannot waive the requirement. If you dropped coverage at some point, you may only be able to convert to an individual policy.

Staying Eligible After Approval

Approval is not permanent. OPM monitors whether you’ve recovered or regained the ability to earn a living, and two triggers can end your annuity.

The first is the 80% earnings threshold. If your wages or self-employment income in any calendar year reach 80% of the current salary of the position you retired from, OPM treats your earning capacity as restored, and payments stop 180 days after that calendar year ends.¹⁵ The measure is against the position’s current salary, so pay raises after your retirement raise the target too. If your earnings later drop below 80% and you haven’t actually recovered medically, OPM will restore the annuity the following January.

The second trigger is medical. OPM can require updated medical information or a reexamination every year until you turn 60.³ If OPM determines you’ve recovered, your annuity ends either when the government reemploys you or one year after the recovery finding, whichever comes first.¹⁵

Expect a periodic questionnaire, Form RI 30-1, asking about your employment, current earnings, and medical condition. You have 90 days to return it, along with updated clinical findings and a prognosis from your physician. Miss the deadline and OPM can suspend your payments until the information arrives.¹⁶

If Your Application Is Denied

A denial is not the end. You have 30 calendar days from the date of OPM’s decision letter to request reconsideration in writing, including your name, address, date of birth, claim number, and the basis for disagreement.¹⁷ This is the moment to add stronger medical evidence, updated physician statements, or clarifications aimed at whatever OPM said was missing. OPM can extend the 30-day window if you weren’t notified of it or circumstances beyond your control kept you from filing.

If reconsideration also fails, you generally have 30 days to appeal to the Merit Systems Protection Board. That proceeding works like a hearing before an administrative judge who takes evidence and makes an independent decision.

Expedited Processing for Terminal Illness

Applicants with a life expectancy of one year or less, or with certain severe conditions such as ALS, metastatic cancer, end-stage renal disease, or class IV cardiac disease, may qualify for expedited review. The agency’s retirement counselor flags the case for OPM’s disability branch at submission with a special cover sheet. Fast-tracking doesn’t waive any eligibility requirement; the same service and timeliness rules still apply.³
