Millions of Americans claim Social Security the moment they turn 62, then pick up a part-time job to make ends meet.
What many don't realize is that the Social Security Administration can claw back part of those benefits if their earnings cross a certain line.
It's called the retirement earnings test, and it trips up hundreds of thousands of filers every year.
If you claim benefits before your full retirement age, which ranges from 66 to 67 depending on your birth year, the SSA withholds $1 in benefits for every $2 you earn above an annual limit.
For 2025, that threshold sits at $23,400.
Earn $33,400 at your old job, and roughly $5,000 of your benefits gets withheld.
The numbers change in the year you actually reach full retirement age.
The limit jumps to $62,160 for 2025, and the withholding rate softens to $1 for every $3 earned above that line.
Once you hit full retirement age, the test disappears entirely.
You can earn any amount and keep every dollar of your benefit.
The part that catches people off guard is what happens to the withheld money.
When you reach full retirement age, the SSA recalculates your monthly benefit upward to account for the checks it withheld.
So a retiree who lost $6,000 to the earnings test could see a meaningful bump in their permanent monthly payment.
There's a reason this rule generates so much confusion.
The Social Security statement and online calculators don't always flag it clearly, and many people assume "retirement" means they're done working.
In reality, the test only counts wages and self-employment income.
Pensions, investment dividends, IRA withdrawals, and rental income don't count toward the limit.
Only earnings before the month you reach full retirement age are subject to the test.
If your birthday lands in June, income from July onward is exempt for that year, which can create a planning opportunity for anyone close to the threshold.
For households weighing whether to work while collecting early benefits, the math often favors waiting or reducing hours.
Someone earning $40,000 part-time could lose a chunk of benefits now, only to have it restored later.
The break-even point depends on how long they expect to draw benefits and whether they need the cash today.
The SSA does offer relief in one case: if your benefits were wrongly withheld, you can request a waiver or file an appeal.
Overpayments can also be repaid gradually.
But the cleaner strategy is to report estimated earnings to the SSA early, so withholding is handled correctly from the start.
Anyone nearing 62 who plans to keep working should run the numbers before filing.
A short delay in claiming, paired with even modest continued earnings, can change the lifetime payout by tens of thousands of dollars.
The earnings test isn't a penalty so much as a timing mechanism, but it only helps if you understand it before the first check arrives.
Our take: the earnings test rewards patience more than it punishes work.
If you can hold off claiming until full retirement age, you sidestep the withholding entirely and lock in a larger check for life.
Final Thoughts
For anyone who needs income now, at least walk into the decision with clear eyes about what those early checks really cost.
