When Social Security checks are trimmed for people who keep working, only one kind of income is measured. The agency’s retirement earnings test looks at wages and net self-employment earnings, and it leaves out pensions, annuities and investment income. A retiree under full retirement age can have a sizable pension and a brokerage account without either one costing a dollar of benefits.

The Social Security Administration spells this out on its page on receiving benefits while working. It says the agency counts only the wages from a job or the net profit from self-employment, and that bonuses, commissions and vacation pay count too. Pensions, annuities, investment income, interest, veterans benefits and other government or military retirement benefits do not.

What counts toward the limit and what does not

SSA’s April 2026 working-beneficiary booklet repeats the same split and adds capital gains to the list of income the agency does not count. The federal rule that defines earnings for the test, 20 CFR 404.429, is the regulation that defines what earnings mean for the test.

A retiree under full retirement age who has a pension and investment income should look at only the paycheck side before worrying about the test. A $40,000 pension plus $15,000 in dividends adds nothing to the number SSA compares with the limit. A part-time job paying $30,000 does.

The self-employed get one more point in their favor. SSA’s page counts net profit from the business, not gross receipts, so the expenses of running a small shop, a farm stand or a side trade come off before the comparison with the limit. Veterans benefits and other government retirement benefits also stay outside the count, which matters for retirees who draw several checks.

The 2026 limits and how much gets withheld

For 2026, the limit is $24,480 for anyone under full retirement age all year, according to SSA’s earnings test table. SSA withholds $1 in benefits for every $2 earned above that amount. In the year a person reaches full retirement age, the limit is $65,160 and the rate is $1 withheld for every $3 above it, counting only earnings in the months before the birthday month.

The limits rise with wages. The same table lists $23,400 and $62,160 for 2025, so the 2026 figures are $1,080 and $3,000 higher. Anyone who planned work around last year’s numbers has more room this year.

SSA’s booklet gives two worked examples. A person who files at 62 in January 2026 with a $600 monthly benefit and earns $26,080 is $1,600 over the limit, so SSA withholds $800. A person who reaches full retirement age in November 2026 and earned $68,520 from January through October is $3,360 over the higher limit, so SSA withholds $1,120.

The booklet also describes a monthly rule for people who retire partway through a year. A person is considered retired in any month with earnings of $2,040 or less, and the agency’s page says the special rule lets SSA pay a full benefit for any whole month it considers a person retired, no matter what the year’s earnings add up to.

That matters for someone who earns heavily early in the year and then stops. The booklet’s example is a person who retires at 62 on October 30, 2026 after earning $45,000 and then works part time at $500 a month. That person is still paid for November and December under the monthly rule.

Withheld money is not simply gone

Benefits held back by the test are not lost for good. SSA says it will recalculate the benefit at full retirement age to give credit for the months it reduced or withheld payments because of excess earnings. The booklet puts it plainly: the benefit will increase at full retirement age to account for the benefits withheld.

The booklet’s own example shows the scale. A $910 monthly benefit with 12 months withheld becomes $975 after the recalculation. Still, a higher check later is no help to someone who needed the money in the year it was withheld, which is why the planning happens before the first payment.

When the test stops mattering

Starting with the month a person reaches full retirement age, earnings no longer reduce benefits, SSA says, no matter how much is earned. Full retirement age depends on birth year, according to SSA’s age-reduction page: 66 for people born 1943 to 1954, rising in two-month steps to 66 and 10 months for 1959, and 67 for anyone born in 1960 or later.

The page also shows what filing early does to a check. A person born in 1960 or later who claims at 62 gets a retirement benefit reduced by 30 percent. Add the earnings test on top, and a worker who claims at 62 and keeps a full-time job can see a benefit that is both permanently smaller and temporarily withheld.

For someone with a pension and investments who wants to keep a modest job, the answer to the earnings question is therefore narrow. Only the work income counts, the 2026 limit is $24,480 until the year full retirement age arrives, and the pension and the portfolio sit outside the test.

Working before full retirement age with a pension on the side?

The risk for someone under full retirement age is claiming at 62 and then taking a job that pushes wages past $24,480. Benefits get withheld, the 30 percent early-claiming cut stays, and the pension that never counted toward the test gives no warning either way.

The Social Security Claiming & Family Benefits Kit puts the 2026 earnings-test rules next to a claiming calculator (Excel) for claiming age, break-even and survivor benefits. Its Part 4 is titled “Still Working? The Earnings Test,” and the spousal and survivor sequencing worksheets cover the households where two benefits are in play.
