The FERS Annuity Supplement is essentially bonus money on top of your federal pension that you can receive before Social Security kicks in. Often called the “bridge payment” or “special annuity supplement,” it is designed to bridge the gap between your retirement date and age 62, when you become eligible for Social Security.
Because Social Security is a core income source for federal employees, retiring at age 57 can leave a significant income gap. The FERS Annuity Supplement fills that gap, providing a monthly payment from the day you retire until you turn 62. But to get the most out of this benefit, you need to understand who qualifies, how it is calculated, and the rules that govern it.
Who Qualifies for the Supplement?
To qualify for the FERS Annuity Supplement, you must be eligible for an immediate, unreduced pension. For most federal employees, this means reaching your Minimum Retirement Age (MRA)—which is typically 57—with at least 30 years of service. Alternatively, you can qualify if you retire at age 60 with at least 20 years of service.
Special provision employees, such as law enforcement officers and firefighters, have different rules. They qualify as long as they meet the requirements for a normal special provision retirement, which is typically age 50 with 20 years of service, or any age with 25 years of service.
How the Supplement is Calculated
The amount you receive from the FERS Annuity Supplement is based on your years of federal service and your projected Social Security benefit at age 62. The formula takes your years of service, divides it by 40, and multiplies that percentage by your age 62 Social Security benefit.
For example, if you have 20 years of service, 20 divided by 40 is 50%. If your projected Social Security benefit at age 62 is $2,000 a month, your supplement would be 50% of that, or $1,000 a month. This means you would receive an extra $12,000 a year from retirement until age 62. The more years of federal service you have, the larger your supplement will be. If you have 40 years of service, you would receive your entire age 62 Social Security benefit amount as your supplement.
The Earnings Limit
One of the most important rules to understand about the FERS Annuity Supplement is the earnings limit. If you retire and only receive passive income—such as your pension, TSP withdrawals, or rental income—your supplement will not be affected. However, if you go back to work and earn a salary or wages, you are subject to the earnings test.
For 2026, the earnings limit is approximately $24,000. If your earned income exceeds this limit, your supplement will be reduced by $1 for every $2 you earn over the limit. For example, if you earn $34,000 from a part-time job, you are $10,000 over the limit, which means your supplement for the following year will be reduced by $5,000. If you earn enough, your supplement could be reduced to zero. Note that for special provision employees, this earnings test does not apply until they reach their MRA (typically age 57).
Common Mistakes to Avoid
When planning for the FERS Annuity Supplement, there are a few critical mistakes you must avoid. First, remember that the supplement stops at age 62—it is a hard stop, regardless of whether you choose to delay Social Security. If you plan to delay Social Security until age 65 or 70, you need to prepare for the income gap that will occur between age 62 and when your Social Security begins.
Second, be aware that the supplement does not receive Cost of Living Adjustments (COLAs). The amount you receive when you retire is the amount you will receive until age 62, so you must account for inflation in your budget. Finally, remember that the supplement is fully taxable. The gross amount you calculate will be reduced by taxes, so be sure to plan your strategy based on the net amount you will actually receive.
