FERS Annuity Supplement: Eligibility, Earnings Test & Calculation Explained

The FERS Annuity Supplement, also known as the Special Retirement Supplement, provides early retirees with additional income before they become eligible for Social Security. This benefit is available to certain federal employees who retire under specific conditions, such as reaching the Minimum Retirement Age (MRA) with at least 30 years of service or at age 60 with 20 years of service. The supplement is calculated based on an estimate of what the retiree would receive from Social Security, adjusted for their years of service under FERS. It's important to note that the supplement is subject to an earnings test, reducing the benefit if the retiree's income exceeds a certain threshold.
