FERS Special Retirement Supplement: Complete Guide

What is the FERS Supplement?

The FERS Special Retirement Supplement (SRS) is a monthly payment for certain federal employees who retire under FERS before age 62. It approximates the Social Security benefit you earned during your federal service, bridging the gap until you become eligible for Social Security at age 62.

Who is eligible?

• Employees retiring at their FERS Minimum Retirement Age (MRA) with 30+ years of service.
• Employees retiring at age 60 with 20+ years of service.
• Special-category employees (law enforcement, firefighters, air traffic controllers) retiring under their mandatory rules.
• Employees retiring under discontinued service or early-out (VERA) — supplement begins at MRA.

MRA + 10 retirements and deferred retirements are not eligible for the FERS Supplement.

How is the FERS Supplement calculated?

OPM uses a simplified formula:

Only civilian federal service under FERS counts toward the "years of FERS service" factor. Military service, even if bought back for retirement, does not increase the FERS Supplement. Years are rounded down to whole years.

Example. Estimated Social Security benefit at 62 is $1,600/month, and you retire with 25 years of FERS service:

The earnings test

Starting the year you reach MRA, the FERS Supplement is subject to the Social Security earnings test. For each $2 of earned income above the annual limit, your supplement is reduced by $1. Only wages and self-employment income count — pensions, TSP withdrawals, interest, and dividends do not.

OPM sends an annual survey (RI 92-22) to report prior-year earnings. Reductions apply the following July. Special-category retirees are exempt from the earnings test until they reach MRA.

When the supplement ends

The FERS Supplement stops the month you turn 62, regardless of whether you actually claim Social Security. It does not receive annual COLAs.

Planning tips

• Model post-retirement work carefully — even modest wages can wipe out the supplement.
• Coordinate the supplement with TSP withdrawals and any spousal Social Security strategy.
• Confirm your MRA and years-of-service counts with your HR office before retiring.
