Retirement today looks very different from what it used to be. For many people, it’s no longer about stepping away from the workforce completely. Instead, it’s about finding balance earning some extra money, staying mentally active, and enjoying a sense of purpose. Across the United States, a growing number of retirees are taking up part-time or freelance roles. Some drive for ride-share apps, while others offer consulting services, teach part-time, or work in local businesses a few days a week.
The reasons are practical as well as personal. With the rising cost of living, groceries, and healthcare, many retirees feel the need for extra income to maintain their lifestyle. Others simply enjoy the rhythm of work, the chance to socialize, and the satisfaction of contributing their skills. In many ways, part-time work has become a smart financial and emotional strategy for retirees who aren’t ready to fully “clock out.” However, before taking that job or gig, it’s important to understand how it might affect your Social Security, taxes, and Medicare costs. Earning even a small amount can change how much you pay or how much you keep.

How Social Security Treats Your Work Income
The Social Security Administration (SSA) allows you to earn money while collecting benefits, but there are limits if you start before your full retirement age (FRA). If you earn more than the allowed amount, part of your benefit may be temporarily withheld.
| Retirement Age Rules (2025) | Details |
|---|---|
| Full Retirement Age (FRA) | 66 for those born 1943-1954; 67 for those born 1960 or later |
| Earnings Limit Before FRA | $22,320 per year; $1 withheld for every $2 earned above this limit |
| In Year You Reach FRA | $59,520 limit; $1 withheld for every $3 earned above this threshold |
| After FRA | No limit; you can earn any amount without a reduction in benefits |
If your benefits are temporarily reduced due to excess earnings, don’t worry the withheld amount isn’t lost. Once you reach full retirement age, Social Security recalculates your benefits and adds back what was withheld, increasing your future payments.

The Tax Side of Working in Retirement
Even after you retire, the IRS doesn’t completely retire from your life. Income from a part-time job or side business is still taxable, and that includes both federal income taxes and payroll taxes for Social Security and Medicare. Many retirees are surprised to find that earning a modest income can also make part of their Social Security benefits taxable.
The IRS uses something called “combined income,” which includes your adjusted gross income, nontaxable interest, and half of your Social Security benefits. Depending on how much you earn, up to 85% of your Social Security may be taxed.
| Filing Status | Combined Income Range | Taxable Portion of Benefits |
|---|---|---|
| Single | $25,000-$34,000 | Up to 50% taxable |
| Single (above $34,000) | – | Up to 85% taxable |
| Married Filing Jointly | $32,000-$44,000 | Up to 50% taxable |
| Married (above $44,000) | – | Up to 85% taxable |
If you’re 73 or older, there’s another tax layer to consider Required Minimum Distributions (RMDs) from retirement accounts like IRAs or 401(k)s. These distributions are taxable and could push you into a higher bracket, especially when combined with part-time income. To avoid surprises, it’s smart to plan your withdrawals and estimated tax payments carefully or consult a tax advisor using resources on the IRS website.
How Medicare Costs Could Rise If You Earn More
One area retirees often overlook is how part-time work affects Medicare premiums. If your income increases, your Medicare Part B and Part D costs might go up because of something called the Income-Related Monthly Adjustment Amount (IRMAA). This applies to higher-income retirees.
In 2025, individuals earning more than $103,000 and couples earning more than $206,000 will pay higher premiums. It’s important to remember that Medicare looks at your tax return from two years prior, so your 2023 income affects your 2025 premiums. That means even a one-time consulting project or investment gain can raise your costs later. You can verify premium brackets and details on Medicare.gov.
The Real Rewards Go Beyond the Paycheck
While the financial benefits of part-time work are clear, there’s also an emotional and social upside that can’t be ignored. Many retirees say working a few days a week helps them stay mentally sharp and connected to others. It offers a sense of identity and purpose something that can fade after leaving full-time work.
Staying active has been linked to lower rates of depression and better overall health among older adults. Beyond money, these intangible benefits are what make post-retirement work truly valuable. It’s a way to stay relevant, useful, and connected in a world that still has much to gain from your experience.
Smart Tips Before You Start Working Again
Before you commit to part-time work, take time to plan ahead. A little preparation can help you keep more of what you earn and avoid benefit reductions later.
- Know the earnings test: If you’re under FRA, calculate how much work income might reduce your Social Security benefits.
- Delay your benefits if possible: Waiting until full retirement age or later can permanently increase your monthly check.
- Watch your tax bracket: Extra income might push you into a higher bracket or affect Medicare surcharges.
- Do what you love: The best part-time jobs are those that keep you happy and fulfilled, not just busy.
Real-Life Example
Imagine Retiree A, age 64, who claims Social Security early and earns $30,000 a year from a part-time job. The 2025 earnings limit is $22,320, so they go over by $7,680. Social Security will withhold $3,840 of their benefits that year. Meanwhile, Retiree B, age 68, earns the same $30,000 but is past full retirement age. Their benefits aren’t reduced at all, though their higher income may make a bigger portion of those benefits taxable.
Working after retirement doesn’t mean giving up your freedom it can enhance it. Whether it’s to stay active, make ends meet, or keep your mind sharp, a part-time job can bring both financial stability and emotional fulfillment. Just take the time to understand how Social Security, taxes, and Medicare interact with your new income. With smart planning, you can enjoy the best of both worlds: extra earnings and a rewarding retirement.
