How an HSA Can Help Pay Your Medicare Costs in Retirement
By Tyler Haskell, CFP®
When people think about Medicare, they often assume that once they turn 65, their healthcare costs are over.
Unfortunately, that’s not true.
Even with Medicare, you’ll likely have expenses such as:
- Medicare Part B premiums (Maybe IRMAA surcharges if you’re over the income limit)
- Medicare Part D premiums
- Medicare Advantage copays
- Medicare Supplement premiums
- Deductibles
- Coinsurance
- Dental, vision, and hearing expenses
- And many more
The good news is that if you’ve been contributing to a Health Savings Account (HSA), you may already have one of the best tools available to help cover those costs.
What Is an HSA?
A Health Savings Account (HSA) is available to individuals enrolled in a qualifying High Deductible Health Plan (HDHP).
HSAs offer one of the best tax advantages available because they provide:
- A tax deduction when you contribute
- Tax-deferred growth
- Tax-free withdrawals for qualified medical expenses
Many financial professionals refer to HSAs as having a “triple tax advantage.”
Can You Keep Your HSA After Medicare?
Yes.
One of the biggest misconceptions I hear is that people lose their HSA once they enroll in Medicare.
That’s not true.
Once you enroll in Medicare, you can’t make new HSA contributions, but the money already in your HSA remains yours forever.
You can continue investing it, allow it to grow, and use it later for qualified medical expenses.
What Medicare Expenses Can an HSA Pay For?
Your HSA can generally be used tax-free to pay for:
✅ Medicare Part B premiums
✅ Medicare Part D premiums
✅ Medicare Advantage premiums
✅ Deductibles
✅ Copays
✅ Coinsurance
✅ Dental care
✅ Vision care
✅ Hearing aids
✅ Long-term care costs
One important exception:
Medicare Supplement (Medigap) premiums are NOT qualified HSA expenses and cannot be paid tax-free from an HSA.
Why This Matters
Let’s say you’ve accumulated:
$10,000 in an HSA.
Instead of paying your Medicare costs from your checking account each year, you could use HSA dollars.
Since qualified withdrawals are tax-free, you’re effectively paying those medical expenses with pre-tax money.
That’s a tremendous benefit during retirement.
Think About It This Way
Many retirees budget for:
- Travel
- Food
- Housing
But healthcare is one of the biggest retirement expenses.
Having an HSA dedicated to medical costs can make those expenses much easier to manage.
One Strategy I Recommend
If you’re still working and eligible to contribute to an HSA, consider paying your current medical expenses out of pocket if you can comfortably afford to do so.
Why?
It allows your HSA investments to continue growing tax-free for future healthcare expenses in retirement.
Many people think of their HSA as another checking account.
I prefer to think of it as a Healthcare Retirement Account.
Don’t Forget About Medicare Enrollment
One important rule:
Once you enroll in any part of Medicare, you’re generally no longer eligible to contribute to an HSA.
If you’re planning to delay Medicare because you’re still working, make sure you understand how your Medicare enrollment date affects your HSA contribution eligibility.
This is one of the most common mistakes I help clients avoid.
My Advice
If you’re in your 50s or early 60s and have access to an HSA, don’t overlook it.
It can become one of the most tax-efficient ways to pay for healthcare in retirement.
By planning ahead, you can reduce the impact of Medicare premiums, copays, and other healthcare expenses while preserving more of your retirement savings.
Don’t Forget to Spend Your HSA During Retirement
Here’s another point that often surprises people.
An HSA is one of the best retirement accounts while you’re alive because you can use it tax-free for qualified medical expenses.
However, if you leave your HSA to anyone other than your spouse, the tax benefits largely disappear.
If your spouse inherits your HSA, it simply becomes their HSA, and they can continue using it tax-free for qualified medical expenses.
But if your children or another non-spouse beneficiary inherit your HSA, the account generally loses its HSA status. The remaining balance becomes taxable income to the beneficiary in the year they inherit it.
That’s why I often tell clients:
“Your HSA is one retirement account you really do want to spend during your lifetime.”
