Millions of Americans claim Social Security before reaching full retirement age, and many of them keep working.
What a lot of those people don't realize is that the Social Security Administration can temporarily withhold part of their monthly benefit if their earnings climb above a set threshold.
This is called the retirement earnings test, and it trips up people every year.
Here's how it actually works, and what it does — and doesn't — do to your money.
In 2025, if you're below full retirement age for the entire year, the limit is $23,400.
Earn more than that, and SSA withholds $1 in benefits for every $2 you go over.
In the year you reach full retirement age, the limit jumps to $62,160, and the withholding is gentler: $1 for every $3 above the line.
Wages from a job and net self-employment income are what SSA looks at.
Pensions, annuities, investment dividends, and other retirement account withdrawals generally don't count toward the test.
Suppose you're 63 and collecting $1,800 a month.
You take a part-time job and earn $33,400 for the year — $10,000 over the lower limit.
SSA would withhold $5,000, which works out to roughly three months of benefits.
Once you hit full retirement age, the earnings test goes away entirely.
You can earn any amount, and your benefit is not reduced.
That's a fact many pre-retirees don't know, and it changes the math on whether to claim early while still working.
There's a second piece people miss: the withheld money isn't gone for good.
When you reach full retirement age, SSA recalculates your benefit upward to account for the months it withheld.
Over time, that can mean a higher monthly check than you'd otherwise have received.
If you can delay claiming until full retirement age, you skip the test altogether and avoid the withholding headache.
If you claim early because you need the cash flow, at least run the numbers first.
The easiest way to check where you stand is your my Social Security account online.
It shows your estimated benefit and lets you report earnings changes.
You can also call SSA directly, though hold times are notoriously long.
Track your year-to-date earnings, not just your salary.
Bonuses, overtime, and a second job all count.
If you're close to a threshold, ask your employer whether you can shift income into January.
And if you get a withholding notice, don't panic — it's usually a timing issue, not a permanent cut.
One more caution: the earnings test is separate from the taxation of benefits.
Even if your benefit isn't withheld, a portion of it can become taxable once your combined income passes certain levels.
Those are two different rules, and people mix them up constantly.
This isn't about scaring anyone away from working in retirement.
Staying employed can be good for your finances and your health.
It's about knowing the rule before the letter arrives.
The takeaway: the earnings test is temporary, and withheld benefits are largely restored later through a higher payment.
Final Thoughts
But the cash-flow hit in the short term is real, and it hits hardest for people who claim early and work full-time.
