What Is the FERS Supplement and How Does the Earnings Test Work?
Quick answer
The FERS Special Retirement Supplement is a bridge payment OPM makes to federal employees who retire with an immediate, unreduced annuity before age 62. It approximates the Social Security benefit you earned during federal service, and it stops permanently at 62 whether or not you claim Social Security then. Beginning the year you reach your Minimum Retirement Age, the supplement is subject to the same annual earnings test that applies to early Social Security. In 2026 the threshold is $24,480, and OPM reduces the supplement by $1 for every $2 of earnings above it. The critical detail is what counts: only earned income, meaning wages and net self-employment income. TSP withdrawals, your FERS annuity itself, rental income, dividends, capital gains, and Roth conversions are not earned income and do not reduce the supplement by a dollar. Despite a 2025 proposal to eliminate it for future retirees, the supplement remains in law.
Not every federal retiree gets the supplement. It goes to those who retire with an immediate, unreduced annuity before 62, which generally means reaching your Minimum Retirement Age with 30 years of service, or age 60 with 20. If you take a deferred retirement, or leave under MRA+10 with a reduced annuity, you do not receive it at all.
Special provision retirees under 6(c), including Border Patrol agents, CBP officers, federal firefighters, and air traffic controllers, are treated differently. They receive the supplement immediately at retirement even if they separate well before their MRA, and the earnings test does not apply to them until they actually reach MRA.
The mechanics lag by a year. OPM surveys supplement recipients annually about the prior year's earnings, and any reduction is applied going forward. That means a year of heavy consulting income does not hit your cash flow immediately, which is exactly why it surprises people when it does.
The supplement survived the 2025 reconciliation fight. The House-passed version of H.R. 1 would have eliminated it for employees retiring after a future date. The Senate removed that provision, and the law as enacted left the supplement intact. Similar proposals can return, which is an argument for modeling your plan without assuming it is permanent.
If you plan to work part time after retiring, the $24,480 threshold is a real planning number, not a footnote. Earning $44,480 costs you $10,000 of supplement.
The supplement ending at 62 does not mean you should claim Social Security at 62. Those are two separate decisions and the income gap between them is often the best conversion window you will ever have.
Because TSP withdrawals do not count as earned income, drawing from the TSP is a different decision from taking a job, even when the dollar amounts match.
- Assuming the supplement continues past 62 or converts into Social Security automatically. It simply ends.
- Believing TSP withdrawals or a Roth conversion will reduce the supplement. They do not. Only earned income does.
- Taking a post-retirement consulting role without modeling the $1 for every $2 clawback above the annual limit.
- Assuming a deferred retirement or an MRA+10 retirement qualifies. Neither does.
- Building a retirement projection that treats the supplement as guaranteed for life rather than as a bridge that terminates on a known date.
