How Social Security Disability Affects Your FERS Retirement Benefits
TFDR Editorial ·
The SSDI Requirement
When you apply for FERS disability retirement, you are also required to apply for Social Security Disability Insurance (SSDI) benefits. This is not optional — it's a condition of receiving FERS disability retirement.
How the Offset Works
Your FERS disability retirement benefit is reduced (offset) by a portion of your Social Security disability benefit:
- First 12 months: Your FERS benefit (60% of high-3) is reduced by 100% of your SSDI benefit
- After 12 months: Your FERS benefit (40% of high-3) is reduced by 60% of your SSDI benefit
What If SSDI Is Denied?
If your SSDI application is denied, you must provide OPM with proof that you applied and were denied. Your FERS disability benefit will not be offset, meaning you'll receive the full 60%/40% without reduction. However, you should continue to pursue SSDI through the appeals process.
The Guaranteed Minimum
Federal law provides a guaranteed minimum annuity. Your total FERS disability benefit cannot be reduced below a certain floor, even after the Social Security offset is applied. This protects annuitants from receiving an unreasonably low payment.
CSRS Offset Employees
If you are a CSRS Offset employee, different rules apply. The offset calculation considers your entitlement to Social Security disability payments, and there are special provisions if your Social Security benefit is less than the CSRS offset amount.
Planning Ahead
Understanding these offset rules before you file helps you plan financially. Many federal employees are surprised by how much their FERS disability payment is reduced by SSDI. Working with a financial advisor who understands federal benefits can help you prepare for the actual income you'll receive.
