The Social Security earnings test punishes working retirees far less in the year they reach full retirement age than in the years before it. For 2026, someone who hits full retirement age during the year can earn up to $65,160 before any benefits are touched, and above that line the agency withholds just $1 for every $3 earned. That is nearly triple the exempt amount and half the bite of the harsher rule that applies to younger claimants. The distinction is worth real money to anyone still drawing a paycheck while easing toward retirement.
Two earnings limits, and why the gap between them is so large
Social Security runs two different versions of the earnings test depending on how close a beneficiary is to full retirement age. A person who is under that age for the entire calendar year faces the strict version: for 2026 the exempt amount is $24,480, and the agency deducts $1 in benefits for every $2 earned above that limit. That rule can wipe out a large share of a modest benefit for a retiree who is still working most of a full-time job.
The year a worker actually reaches full retirement age, everything loosens. The exempt amount jumps to $65,160, and the withholding rate drops to $1 for every $3 over the line. Only earnings in the months before the birthday month count, not the whole year’s wages, which shrinks the exposure even further for someone who reaches that milestone partway through the year. The age at which full retirement is reached is now 67 for people born in 1960 or later, so the higher limit lands squarely on the last stretch of many careers.

How the $1-for-$3 math plays out on a real paycheck
Social Security’s own illustration shows how modest the hit can be. A worker entitled to $800 a month who reaches full retirement age in August and earns $66,000 in the seven months from January through July is $840 over the $65,160 limit. That triggers a withholding of only $280 across those seven months, leaving $5,320 of the $5,600 in benefits intact. From the birthday month forward, earnings no longer matter at all, no matter how high the salary climbs.
Contrast that with the under-full-retirement-age rule on similar earnings. A retiree who stays under full retirement age all year and earns roughly $33,400 against the $24,480 limit loses $4,460 of a $9,600 annual benefit, because the deduction runs at $1 for every $2 over. The same paycheck that barely dents a check in the full-retirement-age year can swallow nearly half of it a year or two earlier, which is why the timing of the milestone carries so much financial weight.
A crucial point is that the earnings test counts only wages and net self-employment profit. Social Security does not count pensions, annuities, investment income, interest, or veterans and other government retirement benefits when tallying earnings against the limit. A retiree living largely on portfolio income and a pension can have substantial cash flow and still face no reduction at all, since none of it is the kind of earned income the test measures.
A separate rule can spare a mid-year retiree even more. In the first year benefits are claimed, Social Security applies a special monthly earnings test: any month in which earnings fall below a monthly limit — one-twelfth of the annual figure, or about $5,430 in the full-retirement-age year — counts as a retired month, and a full benefit is payable for it no matter how high earlier months ran. Someone who sells a business or leaves a high-paying job partway through the year can therefore collect checks for the remaining months even after annual earnings blew past the yearly cap, because the test switches from the twelve-month total to the month-by-month figure. The rule applies for only that one transitional year, then the ordinary annual limit takes over.
Why withheld benefits are not lost for good
The word “holds back” in the rule is literal, and it matters. Money withheld under the earnings test is not a permanent penalty. Once a beneficiary reaches full retirement age, Social Security recalculates the monthly benefit to give credit for the months in which payments were reduced or withheld. The effect is a permanently higher check going forward that gradually returns the withheld dollars over the rest of retirement.
That reframes the earnings test from a tax into something closer to a forced deferral. A retiree who keeps working through the full-retirement-age year is trading a temporary reduction for a larger lifetime benefit, not simply forfeiting the money. Whether that trade is worthwhile depends on cash-flow needs and how the higher recalculated benefit stacks up against the years of full paychecks that produced the withholding in the first place.
The practical takeaway is that the year of full retirement age is the safest year to combine work and Social Security. The exempt amount is at its highest, the withholding rate at its gentlest, only pre-birthday earnings count, and anything withheld comes back later. For a worker weighing one more year on the job against starting benefits, that convergence is the strongest argument the rules offer for doing both at once.
