It’s quite common for retirees to experience a sense of boredom after leaving the workforce. Once you hand in your ID badge and shut down your work computer for the final time, those first few mornings of “What now?” can feel unexpectedly difficult.
However, this empty space can also open the door to new opportunities for enjoyment. Research suggests that retirees who remain physically and socially active are less likely to experience post-retirement blues and may even enjoy longer lives.
Beyond the obvious health advantages, staying active can also have financial benefits. It can help reduce taxes on income sources such as Social Security benefits and Medicare premiums. With 2026 IRMAA surcharges increasing and standard deductions for seniors evolving, your daily activities could play a role in managing taxable income.
Here’s how retirees can use an active lifestyle to navigate the 2026 tax environment while making their leisure activities financially beneficial.
Things to do in retirement: How to stop boredom
The Centers for Disease Control and Prevention notes that maintaining physical activity in retirement can help prevent or manage chronic conditions such as heart disease, stroke, Type 2 diabetes, and certain cancers. Activities like swimming or pickleball can also improve sleep quality and support mental well-being.
But physical exercise is just one way to stay engaged and healthy in retirement:
Volunteering and charitable activities: According to America’s Health Rankings, roughly one in four adults aged 65 and older volunteers each year. Regular volunteering is linked to reduced risks of cognitive decline, dementia, and depression.
“Unretirement”: Surveys indicate that about one in eight older adults have returned—or plan to return—to work in 2026. Re-entering the workforce can restore a sense of purpose and help maintain mental sharpness.
New ventures: Nearly 30% of Americans in their 70s are running their own businesses, while many others use this stage of life to explore new hobbies or develop new skills.
If you’re wondering about the practical payoff beyond health, the answer may lie in your tax return. Staying active—whether through work, volunteering, or hobbies—can also serve as a smart tax strategy.
1. Lower 2026 IRMAA (Medicare premiums) and Social Security taxes
The income-related monthly adjustment amount (IRMAA) is an additional charge applied to Medicare Part B and Part D premiums. It is calculated using your modified adjusted gross income (MAGI) from two years earlier. For 2026, the Social Security Administration uses 2024 tax return data to determine IRMAA charges.
An active retirement can help reduce these costs in several ways:
Reduce MAGI through part-time work. Continuing with consulting or part-time employment can allow you to delay withdrawals from taxable accounts like traditional IRAs or 401(k)s. This may keep your income below 2026 IRMAA thresholds (starting at $109,000 for individuals and $218,000 for couples).
Minimize taxes on Social Security benefits. Earning modest income instead of taking large withdrawals from retirement accounts can reduce the taxable portion of Social Security benefits, potentially keeping it within the 0% to 50% range instead of the 85% bracket.
Lower healthcare and insurance expenses through wellness. Regular exercise improves overall health, which may reduce medical costs. Lower expenses can mean fewer withdrawals from retirement savings, ultimately lowering taxable income.
Wellness perks in Medigap plans. Some Medicare supplemental plans or Medicare Advantage options include free gym memberships or fitness discounts, offering tax-free benefits.
2. 2026 HSA preservation and utilization
A Health Savings Account (HSA) can be a valuable financial tool for retirees who maintain an active lifestyle. Since HSA funds can be used tax-free for qualified medical expenses, they can effectively support many health-related activities.
Unlike a 401(k), an HSA does not require minimum distributions, allowing the balance to grow tax-free over time.
Here are examples of HSA-eligible expenses that benefit active retirees:
Active vision and hearing. Items such as prescription sports eyewear, contact lenses, and hearing aids help maintain participation in social and physical activities.
Exercise-related equipment (with conditions). While general gym memberships are not covered, a doctor’s letter of medical necessity for conditions like obesity or hypertension may allow HSA funds to cover fitness trackers or specialized equipment.
Active recovery needs. Over-the-counter medications, first-aid supplies, allergy treatments, and even sunscreen (SPF 15 or higher) qualify as HSA-eligible expenses without a prescription.
