Updated July 28, 2026. Quick answer: Withheld benefits are not forfeited. When you reach full retirement age your benefit is recomputed to credit the months in which benefits were withheld, which permanently raises the payment from that point on. The earnings test is a deferral, not a penalty — and being told it is a penalty causes people to make genuinely bad decisions about working.
What actually happens to the withheld months
Claiming before full retirement age applies a reduction based on the number of months of early claiming. If the earnings test withholds benefits for some of those months, they are taken back out of that count at full retirement age. The reduction shrinks. The higher payment continues for life.
So the common framing is wrong in a way that costs people money. “I will lose my benefits if I keep working” leads to people turning down work or filing at a worse time. The accurate framing is that benefits are postponed and returned in a higher monthly amount later.
Where it applies and where it stops
| When | Does the earnings test apply? |
|---|---|
| Before the year you reach full retirement age | Yes, at the lower exempt amount |
| In the year you reach it | Yes, but on a much more generous basis |
| From the month you reach it | No. It stops entirely |
Note the last row carefully: the test stops from the month you reach full retirement age, not at the end of that year. Earnings after that month do not affect your benefit at all, however large.
The exempt amounts are wage-indexed and change annually, so no figures appear here.
No dollar amounts appear on this page, deliberately. The earnings-test exempt amounts are wage-indexed under 42 U.S.C. §403(f)(8)(B), the benefit formula bend points reset every year under §415(i), and full retirement age is a schedule that varies by birth year under §416(l). Any figure printed in an article is wrong within a year. Take current figures from the Social Security Administration directly, and take your own numbers from your Social Security statement.
