Millions of Americans claim Social Security before their full retirement age and keep working.
What many don't realize is that the Social Security Administration can temporarily withhold part of those benefits, based on a formula most people have never read.
It's called the earnings test, and it surprises retirees every tax season.
In 2025, if you're below full retirement age for the entire year, Social Security withholds $1 for every $2 you earn above $23,400.
Earn $43,400 at your part-time job, and that's $20,000 over the limit — meaning $10,000 of your benefits get held back.
The year you reach full retirement age, the math loosens up.
The limit jumps to $62,160, and the withholding drops to $1 for every $3 above it.
Once you hit full retirement age, the test disappears entirely.
You can earn any amount with no withholding at all.
Different rules apply if you're self-employed, since the SSA looks at your net earnings from self-employment rather than a W-2.
The part that trips people up: this isn't a permanent loss.
When you reach full retirement age, the SSA recalculates your monthly benefit upward to account for the money that was withheld.
Over time, many people get most or all of it back through higher checks.
A retiree expecting $1,800 a month who suddenly sees $900 withheld may scramble to cover rent or groceries.
That's why financial planners often suggest waiting to claim if you plan to keep working steadily.
There are also special monthly limits in the first year you retire, which can help people who stop working mid-year.
And if your benefits are withheld, your overall taxable income drops too, which can slightly soften the blow at tax time.
One more wrinkle: if you're receiving benefits and your earnings change, you're supposed to report it.
The SSA cross-checks with the IRS, and an unreported raise can trigger an overpayment notice later — a letter nobody enjoys opening.
The takeaway for anyone eyeing an early claim: run the numbers before you file.
If you're earning a solid paycheck, waiting a few years can mean a bigger check for the rest of your life.
Our take: the earnings test isn't a penalty so much as a timing mechanism, but it catches people off guard because nobody explains it at the counter.
Final Thoughts
If you're planning to work and claim at the same time, talk to a tax professional or use the SSA's own calculator first — an hour of homework now beats a surprise letter later.
