Working Part Time in Retirement: How It Changes Social Security, Taxes, and Withdrawals
The word retirement suggests a clean break. You stop working. You switch to withdrawal mode. Your days become your own. In practice, more retirees are blurring that boundary every year, and often for reasons that have nothing to do with running out of money.
According to the Bureau of Labor Statistics, about 38 percent of Americans in their late 60s and early 70s are either working or actively looking for work — up from 28 percent in the early 2000s. Some work because they need the income. Others work because staying engaged, learning new skills, and maintaining social connections improves their quality of life.
Whatever the reason, part-time work in retirement changes the financial picture in ways that are easy to underestimate. The paycheck is visible. The hidden effects on Social Security, Medicare premiums, tax brackets, and portfolio withdrawals are not.
The Upside Is Real
A retiree who earns $18,000 a year from a part-time job from age 62 to 70 can reduce portfolio withdrawals by $144,000 over those eight years. That money stays invested and grows. By age 75, that same retiree might have $200,000 more in their portfolio than someone who never worked in retirement, assuming a 6 percent return. The gap widens from there.
How part-time work affects Social Security benefits
If you claim Social Security before your full retirement age (FRA) and keep working, the Social Security Administration applies an earnings test. In 2026, the limit is $22,320 per year for beneficiaries under FRA. For every $2 you earn above that limit, Social Security withholds $1 from your benefits.
That sounds harsher than it is. The withheld benefits are not lost. They are added back later after you reach FRA, with a small adjustment that accounts for the delay. The net effect is usually neutral or slightly positive — you receive the same lifetime benefits, just shifted to a later date. But the cash-flow effect matters. A retiree who expects $1,800 a month in Social Security and earns $30,000 at a part-time job will see roughly $3,840 of those benefits withheld for the year. That is $320 a month less in hand today, recouped later.
Full Retirement Age vs. Earnings Test
In the year you reach FRA, the earnings limit jumps to $59,520 for 2026, and the penalty drops to $1 withheld for every $3 earned above the limit. Once you hit your FRA birthday, the earnings test disappears entirely. You can earn any amount without losing a dollar of Social Security.
For retirees who want both the Social Security income and a part-time paycheck, the cleanest approach is often: delay Social Security to FRA or later, earn part-time income freely, and treat the delayed Social Security as a higher guaranteed benefit starting at a known date.
Our guide on maximizing Social Security benefits covers the claiming tradeoffs in more detail. The key point for part-time workers: if you plan to work past 62, delaying Social Security is almost always better than claiming early and dealing with the earnings test.
How part-time work affects taxes
Part-time income is taxable. That is obvious. What is less obvious is how part-time earnings cascade into other tax effects.
First, earned income fills the lower tax brackets, which means every dollar you withdraw from a traditional IRA or 401(k) after the part-time paycheck is taxed at a higher marginal rate. If you earn $20,000 from a part-time job and withdraw $30,000 from a traditional IRA, you pay taxes on $50,000 of ordinary income. Without the job, the same IRA withdrawal might be partly taxed at zero percent (within the standard deduction).
Second, earned income can make Social Security benefits taxable. If your combined income — adjusted gross income plus nontaxable interest plus half of Social Security benefits — exceeds $25,000 (single) or $32,000 (married filing jointly), up to 85 percent of your Social Security becomes taxable. Part-time earnings push you above those thresholds faster.
Third, Medicare IRMAA surcharges are based on modified adjusted gross income from two years prior. A year with unusually high earnings can trigger higher Part B and Part D premiums two years later, even if your income dropped back to normal.
The point is not that part-time work is bad. The point is that the net benefit of working is lower than the gross paycheck suggests. A retiree earning $25,000 from a part-time job might keep only $17,000 after counting the increased taxes on IRA withdrawals and Social Security. That is still a positive number, but knowing the real net helps with planning.
Net Income Example: Part-Time Work in Retirement
Scenario: Married couple, age 64. Husband earns $22,000 at a part-time job. Wife has no earned income. They withdraw $35,000 from traditional IRAs.
Without the job: IRA withdrawal of $35,000. Tax on ordinary income: roughly $2,600.
With the job: $22,000 earnings + $35,000 withdrawal = $57,000. More Social Security becomes taxable. Tax roughly $5,900.
Net from the job after tax increase: $22,000 minus $3,300 extra tax = $18,700.
Still positive. Still worthwhile for many retirees. But it is 15 percent less than the headline paycheck, and that gap matters when you are deciding how many hours to work.
The portfolio benefit of working longer
The most powerful effect of part-time work in retirement is not the paycheck itself. It is the reduction in how much you need to withdraw from your portfolio and how many years of withdrawals you skip.
Every year you work in early retirement is a year your portfolio stays invested. Over a five-year period, that difference compounds significantly. A retiree who avoids withdrawing $25,000 a year for five years preserves $125,000 of principal plus the growth that money would have generated. At a 6 percent return, that is roughly $42,000 in additional gains over a decade beyond the $125,000.
Sequence-of-returns risk also decreases. The early years of retirement are the most dangerous because a market downturn combined with withdrawals damages the portfolio permanently. Part-time income that covers basic expenses means you do not have to sell portfolio assets during a bear market. That timing advantage alone can add years of longevity to a withdrawal plan.

Where part-time work fits in different retirement phases
Go-go years: work for engagement and portfolio protection
In early retirement, part-time work can serve as a bridge. It covers basic expenses while you delay Social Security, delay RMDs, and give your portfolio more growth years. The social and mental health benefits are real too. Many retirees who take consulting, teaching, or service roles in their 60s report higher satisfaction than peers who stop working entirely.
Slow-go years: work for optionality
By the mid-70s, the nature of work often changes. Physical demands decrease. Consulting or mentoring roles become more common. The income is lower, but the tax complexity is also lower because the retiree is likely past FRA and past the earnings test. At this stage, work is optional. The portfolio income is usually sufficient, and the job is a choice rather than a necessity.
No-go years: the earnings limit becomes moot
In late retirement, paid work is uncommon. But the financial lesson from decades of part-time work is already baked in: the portfolio is healthier because withdrawals were lower for many years, and the retiree has more flexibility for care costs, housing changes, and unexpected expenses.
When part-time work does not make sense
Part-time work is not always the right answer. A few situations where it works against the plan:
- Health constraints. If work accelerates health decline or makes it harder to manage existing conditions, the income is not worth the tradeoff.
- High tax bracket now, low expected spending later. A retiree with a large traditional IRA, a pension, and generous Social Security benefits may not benefit from adding earned income to an already-full tax picture.
- Caregiving obligations. If a retiree is already providing unpaid care for a spouse or parent, adding paid work can create unsustainable pressure.
- Portfolio is already too large. Some retirees face the opposite problem: they have more than enough to support their spending, and the main concern is RMDs and taxes. Additional earned income only worsens that problem.

Bottom line
Part-time work in retirement is not about avoiding retirement. It is about adding flexibility to a plan that otherwise depends entirely on portfolio withdrawals. Every year of earned income is a year of portfolio preservation, delayed Social Security, and reduced sequence risk.
But the tax effects are real. The Social Security earnings test is manageable. Medicare premium surcharges are avoidable with planning. And the net benefit of working is lower than the gross paycheck, but still positive for the vast majority of retirees.
- Part-time income in your 60s is most valuable when it lets you delay Social Security and reduce portfolio withdrawals.
- The Social Security earnings test withholds benefits temporarily, but they are returned later with an adjustment.
- Run the numbers with and without part-time income so you know the real net benefit before you commit to a schedule.

Frequently asked questions
Can I work part time while collecting Social Security?
Yes. If you are under full retirement age and earn above $22,320 (2026 limit), Social Security withholds $1 in benefits for every $2 earned. Those benefits are restored later. Once you reach FRA, there is no earnings limit.
Does part-time work affect Medicare premiums?
Indirectly. Medicare IRMAA surcharges are based on modified adjusted gross income from two years prior. A year with high part-time earnings plus IRA withdrawals could push your MAGI into a higher IRMAA bracket.
How much can a retiree earn without paying taxes on Social Security?
If your combined income (AGI + nontaxable interest + half of Social Security) is below $25,000 (single) or $32,000 (married filing jointly), your Social Security benefits are not taxed. Part-time earnings add to AGI and can push you past these thresholds even if the job pays modestly.
