The FERS Special Retirement Supplement Explained
The FERS Special Retirement Supplement (sometimes called the "FERS supplement" or SRS) fills the income gap between the day you retire and the day you can collect Social Security at 62. For employees who retire early with a full annuity, it can be worth hundreds of dollars a month.
- The supplement bridges income from retirement until age 62.
- It approximates the Social Security you earned during federal service.
- You must retire with an immediate, unreduced annuity to qualify.
- It is subject to the Social Security earnings test if you keep working.
Who qualifies
The supplement is paid to FERS retirees who leave with an immediate, unreduced annuity before age 62. The most common qualifying groups are employees who retire at their MRA with 30 years, at age 60 with 20 years, and special-provision employees (law enforcement officers, firefighters, and air traffic controllers) who retire under their earlier rules. Employees who retire under MRA+10 with a reduced annuity, and anyone who retires at 62 or later, do not receive it.
How it is estimated
The supplement approximates the portion of your age-62 Social Security benefit that you earned during your FERS-covered federal career. A simplified way to picture it: take your estimated Social Security benefit at 62, multiply by your years of FERS service, and divide by 40. So 30 years of FERS service would yield roughly 30/40 (75%) of that estimated benefit as the supplement.
The earnings test
Once you reach your MRA, the supplement is subject to the same annual earnings test that applies to early Social Security. If you take a post-retirement job and your earned income exceeds the annual limit, the supplement is reduced by $1 for every $2 over the limit. Importantly, the earnings test applies to wages and self-employment income — not to your annuity, TSP withdrawals, or investment income.
When it ends
The supplement automatically stops the month you turn 62, whether or not you actually file for Social Security at that time. It is meant only as a bridge. Many retirees use the years between retirement and 62 to decide when to claim Social Security, which can be delayed to 70 for a larger benefit.

Does the supplement increase with COLAs?
No. Unlike the FERS basic annuity, the Special Retirement Supplement does not receive annual cost-of-living adjustments.
Will working part-time reduce my supplement?
It can. Once you reach your MRA, earned income above the annual Social Security earnings limit reduces the supplement by $1 for every $2 over the limit.
Do law enforcement retirees get the supplement before MRA?
Special-provision retirees can receive the supplement before reaching their MRA, and the earnings test generally does not apply to them until they reach their MRA.
