After age 65, your HSA acts like a traditional IRA for non-medical spending: you pay ordinary income tax but face zero penalties.
If you’re 65 or older, your HSA becomes much more flexible—but it does not become unrestricted. In 2026, the core rule remains the same: HSA distributions used for qualified medical expenses are tax-free, while nonqualified withdrawals are taxable. What changes after age 65 is the 20% additional tax on nonqualified withdrawals; that extra tax no longer applies once you reach 65.
That makes the HSA a valuable retirement planning tool, especially when used correctly for Medicare premiums, long-term-care costs, and carefully documented reimbursements. CMS also updated the 2026 Medicare premium amounts, and the IRS updated the 2026 HSA limits and long-term-care premium caps.
Key Takeaways
- After age 65, nonqualified HSA withdrawals are still taxable, but the 20% additional tax is gone.
- The IRS allows HSA funds for Medicare and other health care coverage if you are 65 or older, but not for Medigap premiums.
- For 2026, the standard Medicare Part B premium is $202.90 per month.
- If you must buy Part A, the 2026 monthly premium is $311 or $565.
- If you are enrolled in Medicare, your HSA contribution limit becomes zero starting with that month.
- There is no blanket “stop contributions 6 months before Medicare” rule. The real issue is your actual Medicare effective date, including retroactive Part A coverage if you enroll after 65. (medicare.gov)

The Age 65 Rule: What Actually Changes
Turning 65 does not change the basic tax-free HSA rule. It changes the penalty structure.
Before 65, a nonqualified HSA withdrawal is generally hit with ordinary income tax plus the 20% additional tax. After 65, the 20% additional tax disappears, but ordinary income tax still applies if the withdrawal is not for qualified medical expenses. That is why the HSA becomes more flexible after 65, but not “free money.”
Medicare Premiums You Can Pay With HSA Funds
The IRS says HSA funds can be used for qualified medical expenses, and Pub. 502 specifically treats Medicare Part A, Part B, and Part D premiums as medical expenses in the right circumstances. Pub. 969 also says that, for HSA purposes, you may use tax-free distributions for Medicare and other health care coverage if you are 65 or older, except for Medicare supplemental policies such as Medigap.
Generally HSA-eligible premium uses
- Medicare Part A premiums, if you are voluntarily buying Part A.
- Medicare Part B premiums.
- Medicare Part D premiums.
- Other Medicare-related coverage premiums if they fit the IRS rule for people age 65 or older and are not Medicare supplemental coverage.
The Medigap trap
Medigap premiums are not qualified HSA medical expenses. The IRS guidance is explicit: Medicare supplemental policies, such as Medigap, are excluded from the HSA premium rule. If you take HSA money for Medigap, the withdrawal is taxable; after age 65, it is still not subject to the 20% additional tax.
The Updated “Shoebox Strategy” for Retirees
The so-called shoebox strategy is really a recordkeeping strategy. You pay the medical expense out of pocket, save the documentation, and later reimburse yourself from the HSA for the exact qualified amount. The IRS rules focus on whether the expense was incurred after the HSA was established, whether it was qualified, and whether it was already reimbursed or deducted elsewhere.
Practical correction: The IRS rules do not create a blanket yearly reimbursement deadline inside the HSA rules. In practice, delayed reimbursement works because the tax treatment depends on the qualifying expense and your records, not on when you pull the money out.
How to do it correctly in 2026
- Pay the premium or medical bill. Keep the invoice, premium notice, or other proof of the expense.
- Keep your HSA records together. The IRS says you should be able to show that the distribution was used exclusively for qualified medical expenses and was not previously reimbursed.
- Reimburse yourself from the HSA for the exact qualified amount. If the expense qualifies, the distribution is tax-free.
- Report the HSA correctly on Form 8889. Form 8889 is the form that reports HSA contributions and distributions and calculates any taxable amount. (irs.gov)
Why the Age 65 HSA Rule Still Matters
Here is a simple, illustrative comparison using a 24% federal tax rate and no state tax. This is just a planning example, not a tax rule. The numbers are based on the IRS rule that a nonqualified HSA withdrawal after age 65 is taxable but not subject to the 20% additional tax.
| Scenario | Gross amount | Tax effect | Net spendable amount |
|---|---|---|---|
| Qualified HSA medical expense | $10,000 | Tax-free if qualified | $10,000 |
| Nonqualified HSA withdrawal after 65 | $10,000 | Ordinary income tax only | $7,600 |
| Taxable IRA/401(k) withdrawal needed to net $10,000 | $13,157.89 | 24% federal tax only | $10,000 |
If you want maximum flexibility in retirement, the HSA is still one of the best accounts you can have—because qualified medical spending stays tax-free, and even nonqualified spending after 65 avoids the 20% penalty.
The Medicare Contribution Myth: What to Stop, and When
A common mistake is to think you must stop HSA contributions six months before Medicare Part A starts. That is not the IRS rule. The actual rule is simpler: once you are enrolled in Medicare, your HSA contribution limit becomes zero starting with that month.
The planning trap is that Medicare Part A can be retroactive for up to 6 months if you sign up after age 65, and it cannot start earlier than the month you turned 65. That means contributions made during the retroactive Part A period can become excess contributions. (medicare.gov)
Bottom line: Don’t use a blanket six-month HSA stop rule. Use your actual Medicare effective date, then back into the retroactive Part A window if you enrolled after 65. (medicare.gov)
2026 HSA Contribution Limits if You Are Still Eligible
If you are 65+ but not yet enrolled in Medicare, and you still meet the HSA eligibility rules, you may continue contributing. For 2026, the IRS says the HSA contribution limits are $4,400 for self-only coverage and $8,750 for family coverage.
| 2026 HSA coverage type | Maximum annual contribution |
|---|---|
| Self-only HDHP coverage | $4,400 |
| Family HDHP coverage | $8,750 |
The contribution limit drops to zero once Medicare enrollment begins, so timing matters.
Long-Term Care Premiums and Spousal Expenses
The IRS also updates the age-based limit for qualified long-term care insurance premiums each year. For taxable years beginning in 2026, the limits are as follows.
| Attained age before year-end | 2026 LTC premium limit |
|---|---|
| 40 or less | $500 |
| More than 40 but not more than 50 | $930 |
| More than 50 but not more than 60 | $1,860 |
| More than 60 but not more than 70 | $4,960 |
| More than 70 | $6,200 |
Those limits are indexed and can change again in future years.
What about a spouse or dependent?
Pub. 969 says qualified medical expenses can include those of you, your spouse, and your dependents. But there is an important Medicare caveat: if you are under 65, Medicare premiums for a spouse or dependent who is 65 or older are generally not qualified HSA expenses. If you are 65 or older, the Medicare premium rule is much broader, but Medigap is still excluded.
Forms and Recordkeeping You’ll Actually Use
For HSA distributions, the trustee reports the withdrawal on Form 1099-SA, and HSA contributions are reported on Form 5498-SA. You generally report HSA contributions, distributions, and any taxable amount on Form 8889 with your federal return. (irs.gov)
The IRS also emphasizes recordkeeping: keep proof that the expense was qualified, that it was not previously reimbursed, and that the distribution was used exclusively for the qualified medical expense.
Frequently Asked Questions
Can I use HSA funds to pay Medicare premiums if they come out of Social Security?
Yes, if the premium itself qualifies under the HSA rules. The payment channel does not change the underlying tax rule; the key is to keep your premium records and HSA records together so you can show the expense was qualified.
Can I use HSA funds for Medigap?
No. Medigap is specifically excluded from the HSA premium rule.
If I’m over 65, is a nonqualified HSA withdrawal still penalized?
It is still taxable as ordinary income, but the 20% additional tax no longer applies after age 65.
Can I still contribute to an HSA after I enroll in Medicare?
No. Beginning with the first month you are enrolled in Medicare, your HSA contribution limit becomes zero. If Medicare enrollment is retroactive, contributions made during the retroactive period can be excess contributions. (medicare.gov)
What is the 2026 standard Medicare Part B premium?
The standard Part B premium is $202.90 per month for 2026.
Conclusion
For 2026, the big HSA planning points after age 65 are straightforward: nonqualified withdrawals lose the 20% penalty, Medicare premiums can often be paid tax-free if they qualify, Medigap is still excluded, and HSA contributions stop once Medicare enrollment begins. The most important planning mistake to avoid is relying on an outdated “stop contributions six months early” rule instead of using your real Medicare effective date and retroactive Part A timing.
