FERS Disability Retirement 2026: Rules, Pay, and How to Apply

Last Updated: March 29, 2026 Reading Time: 8 min

If a medical condition makes it impossible to do your federal job, FERS disability retirement exists for exactly this situation. It's not workers' comp. It's not SSDI. It's a separate OPM-administered benefit that pays you a percentage of your high-3 salary and lets you keep your FEHB.

But the process is slow, the rules are specific, and most employees don't understand how the payments actually work. Here's everything you need to know.

Key Takeaways

• FERS disability retirement requires just 18 months of creditable service, not the 5 years needed for a regular pension.
• Year one pays 60% of your high-3 average salary (minus Social Security disability). Year two onward pays 40% of your high-3 (minus 60% of SSDI).
• You don't need to be totally disabled. You just need to be unable to do the duties of your specific position.
• Your agency must confirm it can't reassign you to a vacant position at the same grade and pay.
• At age 62, your disability annuity automatically converts to a regular FERS pension.
• OPM processing takes 6 to 12 months. Plan your leave and finances accordingly.

Who Qualifies for FERS Disability Retirement

You're eligible if you meet all four conditions:

1. At least 18 months of creditable civilian service. This is much lower than the 5-year requirement for a regular FERS pension. Even relatively new employees can qualify.

2. A medical condition that prevents you from doing your job. The condition must be expected to last at least one year. It can be physical (back injury, heart condition, autoimmune disease) or mental (PTSD, major depression, anxiety disorder). OPM requires medical documentation from your treating physician.

3. Your agency can't accommodate you. Your agency must certify that it has considered reassigning you to a vacant position at the same grade and pay within your commuting area, and that no such position exists (or that you've declined a reasonable offer).

4. You apply within one year of separation. If you're still employed, your agency can submit the application on your behalf. If you've already separated, you have 12 months from your separation date to file.

One thing that trips people up: you don't need to be unable to work at all. If you're a GS-13 criminal investigator who can no longer do fieldwork due to a knee injury, you may qualify even though you could work a desk job at a different agency. The standard is your specific position, not all work.

How FERS Disability Pay Works

The payment formula changes after the first year and again at age 62:

Period	Payment Formula	Example (High-3: $80,000)
Year 1	60% of high-3, minus 100% of SSDI	$48,000 minus SSDI
Year 2 through age 62	40% of high-3, minus 60% of SSDI	$32,000 minus 60% of SSDI
Age 62+	Converts to regular FERS annuity	1% x high-3 x total service years

The Social Security offset matters. If you're also receiving Social Security Disability Insurance (SSDI), that amount gets subtracted from your FERS disability payment. In year one, it's dollar-for-dollar. After year one, 60% of your SSDI gets subtracted.

If your SSDI benefit is large enough, your FERS disability payment could be very small or even zero. But you're still considered a disability retiree for purposes of FEHB continuation and other benefits.

Example with SSDI:

A GS-12 employee with a high-3 of $75,000 and SSDI of $2,200/month ($26,400/year):

• Year 1: $45,000 (60% of high-3) minus $26,400 (SSDI) = $18,600/year from FERS plus $26,400 SSDI = $45,000 total
• Year 2+: $30,000 (40% of high-3) minus $15,840 (60% of SSDI) = $14,160/year from FERS plus $26,400 SSDI = $40,560 total

You must apply for Social Security disability when you apply for FERS disability retirement. OPM requires it. Even if SSDI denies you, you need to show you applied.

The Application Process

FERS disability retirement involves three parties: you, your agency, and OPM. Here's the timeline:

Step 1: Gather medical documentation. Get a detailed statement from your physician describing your condition, how it prevents you from performing your job duties, and the expected duration. Generic letters don't cut it. OPM wants specifics about which job functions you can't perform and why.

Step 2: Notify your agency. Your HR office prepares the agency portion of the application (SF 3112 series). This includes a description of your position, confirmation that accommodation or reassignment isn't possible, and your service records.

Step 3: Submit to OPM. The complete package (your application, medical documentation, and agency documentation) goes to OPM's Retirement Services. As of 2026, processing takes 6 to 12 months due to the record backlog at OPM.

Step 4: Wait. During processing, you have options:

• Use your sick leave and annual leave
• Go on Leave Without Pay (LWOP)
• Be separated by your agency (benefits are retroactive if approved)

Step 5: OPM decision. If approved, benefits are retroactive to the day after your last day of pay. If denied, you can request reconsideration within 30 days.

What Happens to Your Other Benefits

FEHB: You keep your health insurance at the regular employee premium rate, same as any retiree. You must have been enrolled for the 5 years immediately before retirement (or since your first opportunity to enroll).

FEGLI: Basic life insurance continues into retirement with the standard post-retirement reduction schedule. Optional coverages can continue if you were enrolled at separation.

TSP: Your TSP balance stays yours. You can leave it invested, withdraw, or roll it over. No new contributions are allowed since you're no longer on payroll.

Social Security: Your disability time counts as creditable service for Social Security purposes. You must apply for SSDI as part of the FERS disability process.

Sick leave: Unlike regular retirement, unused sick leave is NOT added to your service credit for disability retirement. It's used during the application waiting period or forfeited.

The Age 62 Conversion

At age 62, your FERS disability annuity automatically converts to a regular FERS retirement annuity. The formula changes to:

1% x high-3 average salary x total years of service

Here's the important part: your total years of service includes the time you spent on disability retirement. If you became disabled at age 45 with 15 years of service and your disability lasted until age 62, you get credit for those 17 years on disability. That gives you 32 years of total service.

At 62 with 20+ years, the multiplier bumps to 1.1%, so:

1.1% x high-3 x 32 years = 35.2% of your high-3 salary

For someone with an $80,000 high-3, that's $28,160/year as a regular FERS annuity, which then receives annual COLA adjustments.

The high-3 used at conversion is your high-3 at the time of disability retirement, not your high-3 at age 62. It doesn't get adjusted for inflation during the disability period.

Earning Capacity and Working While Disabled

You can work in the private sector while receiving FERS disability retirement, but there's a ceiling. If your earnings from outside employment exceed 80% of the current salary for your former position, OPM considers your earning capacity restored and terminates your disability annuity.

"Current salary" means whatever your former position pays now, not what it paid when you left. So if your old GS-12 position now pays $85,000, the threshold is $68,000.

OPM requires an annual earnings report. If you exceed the 80% threshold in any calendar year, your disability annuity is terminated. You can then apply for a regular deferred FERS annuity at MRA.

Many disability retirees work part-time or in lower-paying roles to stay under this threshold. That's allowed and common.

FERS Disability vs. Workers' Compensation (OWCP)

These are different programs with different rules:

Feature	FERS Disability	OWCP (Workers' Comp)
Administered by	OPM	Department of Labor
Injury requirement	Any medical condition	Must be work-related
Pay rate	60%/40% of high-3	66.7% or 75% of pay
Duration	Until age 62 (then converts)	Until recovery or retirement
FEHB	Continues at employee rate	Continues at employee rate
Tax status	Taxable income	Tax-free
Can receive both?	Generally no. You choose one.	Generally no. You choose one.

You can't usually receive both OWCP and FERS disability payments for the same condition. If you're on OWCP and switch to FERS disability retirement, the FERS disability period counts as creditable service for your eventual age-62 conversion. Many employees on long-term OWCP eventually find it beneficial to switch to FERS disability retirement before age 62 to maximize their regular annuity at conversion.

Calculate Your Disability Retirement Pay

Your FERS disability payment depends on your high-3 average salary. Use our FERS Retirement Calculator to find your high-3, then apply the 60% (year one) or 40% (year two onward) formula.

For the age-62 conversion estimate, the High-3 Calculator helps you pin down your exact high-3 from your highest 36 consecutive months.

Frequently Asked Questions

How much does FERS disability retirement pay?

In the first year, you receive 60% of your high-3 average salary minus 100% of any Social Security disability benefit. After year one, it drops to 40% of your high-3 minus 60% of your Social Security disability benefit. At age 62, it converts to a regular FERS annuity based on your actual years of service.

Do I need to be permanently disabled to qualify for FERS disability retirement?

No. You need to be unable to perform the duties of your specific position due to a medical condition expected to last at least one year. You don't need to be totally disabled. If you could do a different job but can't do yours, you may still qualify.

How long does OPM take to process a disability retirement application?

OPM currently takes 6 to 12 months to process disability retirement applications. During this period, you may use sick leave and annual leave, go on LWOP, or be separated. If approved after separation, benefits are retroactive to the day after separation or the day after pay ended, whichever is later.

Can I work a private-sector job while receiving FERS disability retirement?

Yes, but with limits. If your earnings from outside employment exceed 80% of the current salary for your former position, OPM will restore you to earning capacity and your disability annuity stops. You must report your earnings annually.

What happens to my FEHB if I'm on FERS disability retirement?

You keep your FEHB coverage as long as you were enrolled for the 5 years immediately before retirement (or since your first opportunity to enroll). This is the same rule as regular FERS retirees. You pay the same employee share of premiums.
