More Americans are collecting Social Security while still clocking in somewhere, and a lot of them are about to get an unpleasant letter from the government.
It's called the earnings test, and it can temporarily reduce—or even pause—your monthly check if you're under full retirement age and earning too much.
Here's how it actually works in plain numbers.
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 $40,000 at your part-time job, and that's roughly $8,300 in benefits held back.
If you hit full retirement age sometime during 2025, the math is gentler.
The limit jumps to $62,160, and the withholding is $1 for every $3 above it—and it only counts earnings before the month you reach full retirement age.
The part that trips people up: only wages and self-employment income count.
Pensions, 401(k) withdrawals, rental income, dividends, and interest don't.
So a retiree pulling $30,000 from an IRA and $20,000 from a part-time job only gets dinged on the job income.
Once you reach full retirement age, Social Security recalculates your benefit upward to account for the months it didn't pay out.
Many retirees eventually recover most or all of it through a higher monthly check—but that takes years, not weeks.
There's a special rule for the first year you retire that can soften the blow.
If you retire mid-year and earn more than the annual limit, Social Security can pay you for any full month you didn't work and earned under a monthly threshold ($1,950 in 2025).
It's a niche benefit, but it saves some new retirees thousands.
The real question is whether working is even worth it.
For many people, yes—the extra wages often outweigh the temporary withholding, and the higher earnings can boost your future benefit calculation if they land among your top 35 earning years.
For others, cutting hours to stay under the limit makes more sense.
Practical moves: track your year-to-date earnings, not just your hourly rate.
Call Social Security if your income changes mid-year so they don't over-withhold.
And if you're close to full retirement age, do the calendar math—crossing that threshold mid-year changes which rules apply.
One more thing worth knowing: the earnings test vanishes entirely at full retirement age.
Work as much as you want after that, and your check keeps coming.
Our take: the earnings test isn't a punishment, it's a timing quirk that catches people who never got a clear explanation.
Final Thoughts
If you're planning to work and claim early, run the numbers before you file—a 20-minute call or a quick visit to ssa.gov could save you a year of confusing letters and a smaller-than-expected deposit.
