The Evidence on Working in Retirement: How the Social Security Earnings Test Actually Works

For millions of Americans approaching their sixties, the decision to transition into retirement is no longer a hard stop. Many prefer a phased approach, maintaining part-time work, consulting roles, or transitioning to less demanding careers. Yet, a significant psychological and financial barrier stands in their way: the pervasive fear that earning a paycheck will result in permanently slashed Social Security benefits.[1]

This anxiety is rooted in the Social Security Retirement Earnings Test (RET), a policy that temporarily withholds benefits for individuals who claim early while continuing to work. The prevailing narrative among early retirees is that these withheld funds are permanently lost to the government—a misconception that dramatically alters labor decisions and pushes capable adults out of the workforce.[3]

The evidence, however, reveals that the RET is not a penalty, but rather a deferral mechanism. According to the Center for Retirement Research at Boston College, the reduction in benefits is frequently mischaracterized as a tax. In reality, the government withholds the money in the short term and pays it back incrementally once the worker reaches their Full Retirement Age (FRA).[3]

The mechanics of the 2026 earnings test are precise. For individuals who will be under their Full Retirement Age for the entire year, the annual earnings limit is set at $24,480. For every $2 earned above this threshold, the Social Security Administration withholds $1 in benefits.[5]

If a 64-year-old retiree with a $21,600 annual benefit earns $34,480 in 2026—exactly $10,000 over the limit—the agency will withhold $5,000 for the year. This is typically executed by halting monthly checks entirely until the $5,000 balance is satisfied, after which normal payments resume for the remainder of the year.[1][5]

The critical turning point occurs at Full Retirement Age, which is 67 for anyone born in 1960 or later. At this milestone, the earnings test disappears entirely, allowing unlimited income with no withholding. More importantly, the Social Security Administration recalculates the monthly benefit, permanently increasing future payments to credit the retiree for the exact number of months that were previously withheld.[1][5]

Despite this mathematical reality, behavioral economists note that the psychological friction remains high. Studies by the Center for Retirement Research demonstrate that workers have a remarkably poor grasp of this tradeoff. When presented with standard explanations, many older adults still choose to exit the workforce entirely rather than face the temporary cash-flow disruption.[3]

This premature exit from the labor force carries profound implications, not just for personal finances, but for neurological health. A persistent claim in gerontology is that employment protects older adults from cognitive decline. However, earlier studies relied heavily on correlational evidence, leaving it unclear whether working preserved cognition, or if cognitively healthy people simply chose to work longer.[2]

A landmark April 2026 working paper from the National Bureau of Economic Research (NBER) provides causal evidence to settle the debate. By analyzing local labor market shocks—instances where jobs disappeared due to macroeconomic shifts rather than individual health—researchers isolated the specific impact of employment on the brain.[2]

The NBER data reveals that negative shocks to local labor demand result in substantial declines in cognitive test scores. Specifically, a 10-percentage-point drop in a local area's employment-to-population ratio was associated with a cognitive decline of roughly 0.19 standard deviations among adults approaching retirement.[2]

These protective benefits of employment were most heavily concentrated among men aged 51 to 64. The researchers concluded that remaining in the workforce during these critical pre-retirement years actively delays the onset of age-related cognitive decline and dementia, which currently affects over 6 million Americans.[2]

Transparent uncertainty remains regarding how these cognitive benefits apply across different demographics. The NBER methodology proved less effective at measuring outcomes for women in the same age bracket. Researchers hypothesize this is because women are more heavily concentrated in sectors like healthcare and education, which are less sensitive to the industrial labor shocks used to measure the data.[2]

Beyond cognitive preservation, the macroeconomic argument for keeping older adults in the workforce is gaining traction. Policy analysts at The Heritage Foundation argue that the earnings test is an outdated relic of the Great Depression, originally designed to push older workers out of the labor force to free up jobs for younger citizens.[4]

Today, the U.S. economy faces the exact opposite problem: a structural shortage of skilled labor. Critics argue that by functioning as a perceived 50 percent marginal tax on earnings, the RET actively suppresses economic output and exacerbates labor shortages, suggesting that abolishing the test entirely would boost both personal incomes and overall economic growth.[4]

For those navigating the current system, financial planners emphasize the importance of the "first-year rule." Retirees who leave their primary careers mid-year often have earnings that already exceed the annual limit. The Social Security Administration accommodates this by applying a monthly test—$2,040 in 2026—allowing new retirees to receive full checks for the remainder of the year provided their monthly income stays below that threshold.[1][5]

While the earnings test itself does not permanently destroy wealth, workers must still navigate genuine tax traps. Earning a paycheck while collecting Social Security increases a household's combined income, which can trigger federal income taxes on up to 85 percent of their Social Security benefits and potentially impose surcharges on Medicare premiums.[1]

Ultimately, the evidence strongly supports the value of phased retirement. The combination of delayed portfolio drawdowns, continued employer-subsidized health insurance, and measurable cognitive protection outweighs the temporary friction of the earnings test.[2][6]

The challenge for retirees is shifting their perspective from short-term cash flow to long-term lifetime value. By understanding that withheld benefits are merely deferred and reinvested into a higher baseline payout at age 67, older adults can safely remain in the workforce without fear of penalizing their future.[3][6]
