Millions of Americans claim Social Security before their full retirement age and keep working.
What many don't realize is that the program can temporarily hold back part of those benefits through something called the retirement earnings test.
It's not a penalty you lose forever, but it can catch people off guard when a smaller deposit lands.
If you're below full retirement age and still earning money, Social Security withholds $1 in benefits for every $2 you earn above an annual limit.
In the year you actually reach full retirement age, the rules loosen: the cap jumps to $59,520, and the withholding drops to $1 for every $3 above it.
Once you hit full retirement age, the test disappears entirely, no matter how much you earn.
Wages, self-employment income, and bonuses all count.
Pensions, investment income, and most retirement account withdrawals generally don't.
That distinction matters for retirees who are drawing from a 401(k) while also working part-time.
Say you're 63, collecting $1,800 a month, and you take a part-time job paying $34,000 a year.
You're roughly $11,680 over the 2024 limit, so Social Security withholds about $5,840, or a little over three months of checks.
Your benefits aren't gone, they're deferred.
That's the part people miss: the withheld money isn't forfeited.
When you reach full retirement age, Social Security recalculates and increases your monthly benefit to account for what was held back.
Over a long retirement, many people come out ahead.
But if you need every dollar now to cover rent or groceries, a smaller check can hurt in the short term.
First, figure out your full retirement age, which ranges from 66 to 67 depending on your birth year.
Second, estimate your annual earnings before you claim, and run the numbers through the SSA's earnings test calculator.
Third, if you're close to a threshold, you might time a raise, bonus, or extra shift to stay under the cap.
Fourth, if you started benefits and regret it, you can sometimes withdraw your application within 12 months and repay what you received.
One more wrinkle: only earned income counts.
If you're living off savings, a pension, or investment dividends, the earnings test doesn't touch your check.
That's why two retirees with identical benefits can see very different deposits.
The rule is also why some financial planners suggest delaying your claim if you plan to keep working.
Waiting until full retirement age removes the withholding entirely and typically locks in a larger monthly payment for life.
Our take: the earnings test isn't a trap, but it's poorly explained, and that silence costs people money.
Before you claim early and clock in for a paycheck, spend twenty minutes with the calculator.

Knowing your number beats being surprised by a smaller deposit.
