Retirees earning over $24,480 in 2026 lose $1 in Social Security per $2.

Thousands of Americans are discovering the hard way that taking a job in retirement can quietly slash their Social Security checks if they claim benefits early.

The problem stems from a little-known rule called the earnings test, which withholds money from Social Security payments when retirees work and collect checks before their full retirement age. In 2026, anyone under the full retirement age of 67 will lose $1 in annual benefits for every $2 earned above $24,480. Those who reach their full retirement age in 2026 can earn up to $65,160 before any withholding kicks in, after which the penalty drops to $1 for every $3 earned until they hit their birth month. The rule exists to prevent people from claiming benefits while still earning full-time wages, but it can land retirees in a financial squeeze if they didn’t plan for it.

The impact depends on how much you earn and what other income you have. If your job pays enough to cover living expenses, the earnings test may not matter. But if you rely on Social Security to cover a big chunk of monthly bills, the lost income could force tough choices—like cutting spending or dipping into retirement savings sooner than expected. The good news is that once you reach full retirement age, the test no longer applies, and the Social Security Administration recalculates your benefits to account for any withheld payments. Still, the adjustment doesn’t happen automatically, so retirees need to plan ahead.

To avoid surprises, experts recommend estimating how much you might lose under the earnings test and adjusting your budget accordingly. The limits change every year, so checking the 2027 thresholds before January can help you prepare. For those already working in retirement, the key is to weigh whether the extra paycheck outweighs the risk of reduced benefits. With many Americans behind on retirement savings, every dollar counts—and the earnings test is one more factor to factor into the math before clocking back in.
