Turning 65 with an HSA: Key Decisions Aetna Employees Should Understand

Healthcare Provider Update: Healthcare Provider Information for Aetna Aetna, part of the CVS Health family, has been a key player in the Affordable Care Act (ACA) marketplace, providing health insurance plans to individuals and families. However, significant changes are on the horizon for 2026, as Aetna will exit the ACA marketplace in 17 states, impacting approximately 1 million members. This withdrawal is attributed to the company's challenges in maintaining competitiveness and providing value in a rapidly evolving healthcare landscape. Potential Healthcare Cost Increases in 2026 As the healthcare landscape shifts, substantial premium hikes are anticipated for those enrolled in ACA marketplace plans, with projections of up to 75% increases in out-of-pocket costs due to the potential loss of enhanced federal subsidies. In some states, insurers have filed for rate increases exceeding 60%, driven by surging medical costs and the expiration of premium tax credits established under the American Rescue Plan. For Aetna's former members, this change further complicates their healthcare landscape as they seek new insurance options amid heightened financial pressures. Click here to learn more

1. How Health Savings Accounts (HSAs) function as you approach Medicare eligibility at age 65.

Things Retirees Should Know About Managing Their HSA at Age 65

An important long-term planning tool for many households nearing retirement—especially those transitioning from Aetna—is the Health Savings Account (HSA). Tax-deductible contributions, tax-deferred growth, and tax-free withdrawals for approved medical costs are the three major tax advantages HSAs provide. However, the rules shift as you approach Medicare eligibility, making it essential to understand how HSAs work alongside Medicare and retirement income planning.

“Most people underestimate the strategic value of their HSA in retirement,” observes Brent Wolf, CFP®, Wealth Enhancement. An HSA can evolve from a simple spending bucket into a meaningful tax planning tool after age 60 for many who spent years in the Aetna workforce.

“For high-income earners, an HSA can function like a stealth IRA—one you can tap tax-free when you plan carefully,” Brent explains. However, proper coordination becomes increasingly important as you transition to Medicare.

Prior to Age 65: Eligibility and Contributions

HSA contributions are only permitted during months in which you qualify as an eligible individual, which generally requires coverage under a high-deductible health plan with no disqualifying insurance.

The 2026 HSA contribution limits are $4,400 for individuals and $8,750 for families, and individuals age 55 or older may make an additional $1,000 catch-up contribution before year-end. ¹

One of the most flexible aspects of HSAs is the lack of an IRS time limit for reimbursing qualified medical expenses, ²  as long as those expenses were incurred after the HSA was opened and have not been paid elsewhere. This gives retirees—Aetna professionals included—the ability to withdraw funds tax-free years later by retaining receipts.

This flexibility can be especially valuable when coordinating retirement income strategies, Medicare IRMAA thresholds, Social Security taxation considerations, and Roth conversions.

Medicare Changes the Rules at Age 65

Medicare enrollment becomes a major turning point in HSA planning. Once enrolled in any Medicare coverage—such as Part A—you can no longer make contributions to your HSA. Additionally, Medicare Part A is often applied retroactively for up to six months, which affects HSA eligibility during those months.

To prevent “excess contributions,” many retirees—including those leaving Aetna—choose to stop HSA contributions several months before Medicare begins to account for this retroactive enrollment.

Even after enrolling in Medicare, you may continue using your HSA tax-free to pay for eligible expenses, including premiums for Medicare Advantage (Part C), Part B, and Part D.

After 65: Expanded Withdrawal Options

After turning 65, the 20% penalty no longer applies to HSA withdrawals used for non-medical purposes. Instead, these withdrawals are taxed as ordinary income—similar to IRA distributions. Meanwhile, withdrawals used for qualified medical expenses remain tax-free.

“An HSA offers flexibility for retirees with adequate liquidity,” Brent notes. Aetna retirees may find an HSA helpful as either a tax-free medical expense tool or a supplemental income source.

Estate Planning Considerations

HSAs carry unique rules when passed to beneficiaries. If the spouse is named as the beneficiary, the account becomes the spouse’s own HSA and retains its tax-advantaged treatment.

If the beneficiary is anyone else, the HSA ceases to exist upon the account holder’s death, and the fair market value becomes taxable income that year.

“Make sure your beneficiary designations align with your overall estate plan if your HSA may outlive you,” advises Brent. This helps confirm the account is handled according to your intentions.
