Use your HSA as a tool for retirement savings

A health savings account (HSA) is a great way to help you prepare for future health care costs and retirement while saving on taxes.

August 19, 2025 | 3-minute read

Boost your retirement income with a health savings account

Many people see their HSA only as a way to pay for qualified medical expenses, such as doctor visits or prescriptions. But it can also be a long-term investment vehicle that can play an even greater role in your overall wealth and retirement strategy:

  • You can use your HSA with other retirement accounts to maximize your after-tax retirement income. 
  • Saving in an HSA for retirement gives you a tax-advantaged account dedicated to future medical expenses. 
  • That means you won’t have to dip into other accounts intended for cost-of-living expenses.

There is no “use-it-or-lose-it rule.” The money in your health savings account is yours, even if you change jobs or retire.

Get ahead on taxes in more ways than one

Unlike other accounts, an HSA is one of the only savings vehicles that offers triple tax advantages, making it an effective savings and investment account. You can:

  • Contribute money on a before-tax basis through payroll deduction. 
  • Grow your savings tax-free (interest and investment earnings are not taxed). 
  • Withdraw money income tax-free for qualified medical expenses.

With a 401k, you’ll generally pay taxes when you withdraw funds. But if you use HSA funds for qualified medical expenses, it’s generally income tax-free. Plus, once you turn 65, you can use your HSA for non-qualified expenses. You’ll pay ordinary income tax on those funds, but the 20% tax penalty no longer applies.

Maximize your savings by investing

Investing HSA dollars has many potential tax benefits, giving you another way to save for long-term health care expenses and financial goals. Once your HSA reaches a certain balance, typically $2,000, you can choose to invest a portion of it in one of 2 ways:

Option 1: Optum Bank self-directed mutual funds

Choose from more than 30 mutual funds that average a 4-star Morningstar rating and offer some of the lowest expense ratios in the industry, including life-stage funds. Our asset allocation calculator can help you decide which funds are right for you.

Option 2: Betterment digitally managed investments

Betterment helps take the guesswork out of investing your HSA. Based on your investment goals, it recommends a personalized portfolio of low-cost, exchange-traded funds (ETFs). It also helps keep your HSA investments on track through auto deposits and automated rebalancing. 

There’s more. If you’re saving your HSA for retirement, Betterment can help you manage your investments alongside your other retirement accounts, helping maximize your after-tax retirement income.

Save even more with catch-up contributions

Once you turn 55, you can contribute an additional $1,000 every year to your HSA. This is called a catch-up contribution. If you and your spouse are both 55 or older, you can each contribute an additional $1,000. Your spouse will just need to open their own HSA for their portion. 

Your HSA contributions can really add up. If you can contribute $3,000 a year, you’d get over $1,000 in tax savings. Do that for 5 years, and you’d have $15,000 in your account plus more than $5,000 in tax savings.*

Hank saves for retirement with an HSA

Hank is 60 and preparing for retirement. For the past 5 years, he’s been contributing the maximum amount allowed by the IRS. See how fast his account balance has grown and how much he’s saved on taxes.**

In the past 5 years, Hank contributed a total of $39,500 and saved over $14,870 on taxes.

HSA accounts and Medicare

Health care costs are one of the top financial worries in retirement, especially for people with health conditions. The good news is that the benefits of an HSA don’t stop when you retire.

While you can no longer contribute to your HSA after enrolling in Medicare, you can still use your HSA funds income tax-free to pay for qualified medical expenses. You can also use your HSA to pay for Medicare premiums and qualified out-of-pocket expenses for:

  • Part A (hospital and independent care)
  • Part B (doctor and outpatient care)
  • Part D (prescription drugs)

Note that Medicare does not cover hearing aids or vision, dental or nursing home care.

You can use the money in your HSA like a retirement savings account to pay for qualified medical expenses anytime. But once you turn 65, you can withdraw HSA funds to pay for nonqualified expenses without paying a penalty. You’ll just need to pay ordinary income tax on that amount.

If Medicare is in your future and you have an HSA, there are rules you need to know. Following them can help you save time and avoid tax penalties. For guidance specific to your health care and retirement planning needs, talk with a financial professional or visit the Social Security Administration website.
