An inherited HSA is taxed in one of two very different ways, and the gap between them can be tens of thousands of dollars. If your spouse inherits it, the account stays a health savings account and passes to them completely tax-free. If anyone else inherits it, the account stops being an HSA on the date you die and its full value lands in that person’s taxable income for one single year.
An inherited HSA is fully tax-free only when a spouse is the named beneficiary; the account simply becomes the survivor’s own HSA. A non-spouse beneficiary must include the entire fair market value as of the date of death in their gross income that year. There is no 20% penalty at death, but also no rollover and no way to spread the tax over time.
What happens to an HSA when the owner dies?
What happens to your HSA at death depends entirely on who you named as beneficiary. A surviving spouse keeps the account as their own HSA with no tax. Any non-spouse beneficiary receives the fair market value as ordinary taxable income in the year of death, with no penalty. If no beneficiary is named, the value is reported on your final income tax return through your estate.

A health savings account is the only account in the tax code that can be triple tax-advantaged: deductible going in, tax-free growth, and tax-free withdrawals for qualified medical expenses. That treatment is built around a living owner. When the owner dies, the IRS applies one of three outcomes based on the beneficiary designation on file with the HSA custodian. The table below shows the split that decides everything.
| Question | Spouse beneficiary | Non-spouse beneficiary |
|---|---|---|
| Tax on inheritance | None | Ordinary income tax on full fair market value |
| Can keep it as an HSA | Yes, it becomes their own HSA | No, the account stops being an HSA |
| Rollover allowed | Yes (it is treated as theirs) | No rollover, no stretch |
| When it is taxed | Only on later non-qualified withdrawals | All at once, in the year of death |
| 20% penalty | No | No (penalty is waived at death) |
If your spouse is the beneficiary: the HSA becomes theirs, tax-free
When a spouse is the named beneficiary, the inherited HSA becomes the surviving spouse’s own HSA on the date of death. There is no tax on the transfer and no distribution. The surviving spouse steps into the owner’s shoes: the money keeps growing tax-free, and withdrawals for qualified medical expenses stay tax-free for the rest of their life.
A spouse beneficiary is the only heir treated as if the account had always been theirs. The custodian re-registers the account in the survivor’s name, and nothing is reported as income. A surviving spouse can use the funds for their own qualified medical expenses, or for any purpose after age 65 by paying ordinary income tax on non-medical withdrawals, exactly as the original owner could.
Can my spouse continue and keep contributing to my HSA?
Yes. Because the inherited HSA becomes the surviving spouse’s own account, they can keep contributing to it, provided they meet the normal contribution rules on their own. Making new contributions requires the spouse to have their own qualifying high deductible health plan (HDHP) coverage. Using and holding the inherited balance does not require any coverage.
Owning and spending the inherited HSA carries no health-plan requirement; adding new money does. If the surviving spouse is covered by their own HDHP, they can contribute up to the annual limit and keep building the account. If they are not, the balance still stays fully theirs and fully tax-advantaged; it simply cannot grow through new contributions.
Does the HDHP requirement still apply to a surviving spouse?
Not for holding or spending the inherited HSA. The high deductible health plan (HDHP) rule that governs new HSA contributions is waived for the act of inheriting and using the account. A surviving spouse can keep the money, let it grow, and withdraw it tax-free for qualified medical expenses whether or not they carry HDHP coverage themselves.
If a non-spouse inherits your HSA: the tax cliff most people miss
If a non-spouse inherits your HSA, the account stops being an HSA on the date of death. The IRS treats the entire fair market value as of that date as ordinary income to the beneficiary in that tax year. A child, sibling, friend, or partner cannot keep it as an HSA, cannot roll it over, and cannot stretch the tax across future years.
This is the trap. Most people assume an HSA passes to their children the way a Roth IRA or a brokerage account might, with the tax handled gradually or barely at all. It does not. For any beneficiary who is not the spouse, the HSA ceases to exist as an HSA the moment the owner dies, and the full balance becomes taxable income in that single year.
Why the full fair market value is taxed in the year of death
The full fair market value is taxed because the HSA loses its tax shelter at death for a non-spouse. The account no longer qualifies as an HSA, so the value that was never taxed on the way in becomes ordinary income to the heir. The taxable amount is the fair market value as of the date of death, reported by the custodian and included in the beneficiary’s gross income.
Every deduction the owner took over the years was a promise to pay tax later, when the money left the account. For a spouse, later can be decades away or never. For a non-spouse, later arrives the instant the owner dies, and the custodian reports the date-of-death value for the beneficiary to include as income.
Do non-spouse beneficiaries pay a 20% penalty?
No. The 20% additional tax that normally applies to non-qualified HSA withdrawals does not apply at death. A non-spouse beneficiary pays ordinary income tax at their marginal rate on the fair market value, but the 20% penalty is waived. The tax hit is real, but it is income tax only, not income tax plus a penalty.
During life, spending HSA money on something other than medical care before age 65 triggers both income tax and a 20% penalty. At death, the penalty falls away for every kind of beneficiary. The cost is ordinary income tax at the heir’s marginal bracket, which for a large account is more than enough on its own.
Can a non-spouse roll over or stretch an inherited HSA?
No. A non-spouse cannot roll an inherited HSA into their own HSA and cannot stretch the tax over future years. Unlike an inherited IRA, which a non-spouse can draw down across a 10-year window under the SECURE Act, the HSA gives the beneficiary zero flexibility: the entire fair market value is income in the year of death, full stop.
This is the sharpest reason the inherited HSA is harsher than almost any other retirement account. When a non-spouse inherits a traditional IRA today, they generally have 10 years to withdraw the balance, spreading the taxable income across multiple years and brackets, as our guide to what to do with an inherited IRA explains. The HSA has no such window: no beneficiary account, no withdrawal schedule, no 10-year spread. An inherited IRA is a slope the heir can walk down; an inherited HSA is a cliff they fall off all at once.
How a large HSA can bump your heir into a higher tax bracket in one year
Because the entire value lands in one tax year, a large inherited HSA stacks on top of the heir’s normal income and can push part of it into a higher marginal bracket. It can also raise their modified adjusted gross income enough to trigger Medicare IRMAA surcharges, reduce Affordable Care Act premium subsidies, or expose other income to the 3.8% net investment income tax.
The 2026 brackets show how quickly this compounds. A single heir already earning $180,000 sits in the 24% bracket, which runs up to $201,775 for 2026. Inherit a $90,000 HSA and roughly $22,000 of it is taxed at 24%, but the rest is pushed into the 32% and 35% brackets. Because it all arrives at once, none of it can be shifted to a lower-income year.
| 2026 marginal rate | Single taxable income | Married filing jointly |
|---|---|---|
| 22% | Over $50,400 | Over $100,800 |
| 24% | Over $105,700 up to $201,775 | Over $211,400 up to $403,550 |
| 32% | Over $201,775 | Over $403,550 |
| 35% | Over $256,225 | Over $512,450 |
| 37% | Over $640,600 | Over $768,700 |
The second-order effects matter as much as the bracket. A spike in gross income can cross the $200,000 single or $250,000 joint threshold for the 3.8% net investment income tax, and because Medicare uses a two-year lookback, it can raise the heir’s IRMAA surcharges two years later. For an heir buying coverage on the ACA exchange, one large inclusion year can wipe out the premium subsidy entirely.
Will your state tax it too?
Often, yes. In most states the inherited HSA inclusion follows federal treatment, so the beneficiary owes state income tax on top of the federal bill. In the handful of states that do not conform to federal HSA rules, such as California and New Jersey, HSA balances are already treated as taxable, and the death inclusion is taxed at the state level as well.
This layer is almost entirely missing from the usual explainers, and it can add several thousand dollars. A non-spouse heir in a high-tax state can face a combined federal and state marginal rate well above 40% on the inherited amount. Where the heir lives, not where the owner lived, usually drives the state tax result, so a child in California can owe state tax even if the parent lived in a no-income-tax state.
The one lever a non-spouse has: the 12-month medical-expense offset
A non-spouse beneficiary can reduce the taxable amount by the deceased owner’s qualified medical expenses that were incurred before death and paid within 12 months of the date of death. The heir subtracts those payments from the fair market value before reporting the rest as income. It is the only lever available, and in practice it usually offsets only a small slice of a large account.
The offset sounds generous until you read the fine print. It covers only the decedent’s own qualified medical expenses, only those incurred before death, and only those actually paid within one year of the death. It does not cover the heir’s medical expenses or future care. For a modest account with large final medical bills, it can matter. For a six-figure HSA, it rarely moves the needle.
Which bills qualify for the offset
Only three conditions all have to be true. The expense must be a qualified medical expense of the deceased owner, it must have been incurred before the owner’s death, and it must be paid within 12 months after the date of death. Final hospital, hospice, and physician bills for the owner are the typical qualifiers. The heir’s own costs and any post-death expenses never count.
- Gather the deceased owner’s unpaid qualified medical bills that were incurred before death.
- Pay them within 12 months of the date of death and keep the receipts.
- Subtract the total paid from the fair market value of the HSA.
- Report only the remaining amount as taxable income.
How to report an inherited HSA on your taxes
The HSA custodian reports the date-of-death fair market value to the beneficiary on Form 1099-SA, using the distribution code for death. A non-spouse beneficiary reports the taxable amount on Form 8889 and carries it to their Form 1040 as other income, after subtracting any qualifying 12-month medical-expense offset. A surviving spouse reports nothing, because the account simply becomes theirs.
What happens if no beneficiary is named?
If no beneficiary is named, or the named beneficiary has died, the HSA typically passes to the owner’s estate. The fair market value as of the date of death is then included on the deceased owner’s final income tax return rather than on a beneficiary’s return. The account still loses its HSA status, and the money can be delayed by probate before it reaches heirs.
This is the worst of both worlds: the tax bomb still detonates, and the funds are dragged through the estate. Because the inclusion lands on the decedent’s final return, it can push that final year of income into higher brackets. Naming even one individual beneficiary avoids the estate path and keeps the account out of probate, so the beneficiary form is worth checking today.
How to avoid the HSA tax bomb
The owner controls the outcome while alive. Naming a spouse as primary beneficiary erases the tax entirely. With no spouse, the two effective moves are to spend the HSA down on medical care during life or to name a charity that receives the balance tax-free. Coordinating HSA drawdown with a broader retirement tax plan keeps the account from becoming a one-year income spike for your heirs.
Everything about the inherited HSA problem is decided before death, which is the good news. These are the levers an owner can pull, in rough order of impact.
Name your spouse as primary beneficiary
If you are married, naming your spouse as the primary HSA beneficiary is the single cleanest fix. It converts the account into their own HSA at your death with zero tax and full flexibility. Confirm the designation directly with your HSA custodian, because a beneficiary form filed years ago may still name an estate, an ex-spouse, or no one at all.
If you have no spouse: spend the HSA down while you’re alive
Without a spouse to inherit tax-free, drawing the HSA down during retirement is often the most tax-efficient path. Reimbursing yourself for qualified medical expenses is tax-free, and after age 65 you can withdraw for any purpose by paying only ordinary income tax, with no penalty. A smaller balance at death means a smaller inclusion for your heirs.
After age 65 an HSA behaves much like a traditional IRA for non-medical withdrawals: the money comes out at ordinary income rates. That flexibility makes the HSA a candidate to draw down deliberately in lower-income years, alongside decisions about Roth conversions and the timing of Social Security. Reimbursing yourself for qualified medical expenses converts a future tax bomb into present-day tax-free benefit.
Consider naming a charity to zero out the tax
Naming a qualified charity as the HSA beneficiary can eliminate the income tax entirely. A charity receiving the HSA balance owes no income tax on it, so the full fair market value goes to the cause rather than partly to the IRS. For charitably inclined owners with no spouse, this can be a cleaner outcome than leaving the account to children who would face a full ordinary-income inclusion.
Should you leave an HSA to your children?
Usually the HSA is one of the least tax-efficient accounts to leave to children. A child inheriting an HSA takes the entire fair market value as ordinary income in one year, with no penalty but no stretch. If you want to leave assets to children, a Roth IRA or taxable brokerage account is generally friendlier, and the HSA is better spent down or directed to a spouse or charity.
None of this means an HSA is a bad account to own. During life it remains one of the most powerful tax shelters available, and how it compares to other retirement buckets is covered in our look at the HSA versus a Roth IRA and how the HSA works as a retirement account in 2026. The point is simply to build the exit plan while you can still choose it.

Frequently asked questions
Can my spouse continue my HSA after I die?
Yes. A surviving spouse who is the named beneficiary keeps the HSA as their own account with no tax. They can spend it tax-free on qualified medical expenses, let it grow, and even keep contributing if they have their own high deductible health plan coverage. The spouse is the only beneficiary who steps directly into the owner’s position.
Do non-spouse beneficiaries pay taxes on inherited HSAs?
Yes. A non-spouse beneficiary must include the HSA’s full fair market value as of the date of death in their gross income for that year, taxed at their ordinary marginal rate. The amount can be reduced only by the deceased owner’s qualified medical expenses paid within 12 months of death. There is no rollover and no way to spread the tax.
Can a non-spouse roll over inherited HSA funds into their own HSA?
No. Only a surviving spouse can treat an inherited HSA as their own. A non-spouse cannot roll the funds into their own HSA and cannot stretch the tax across years the way an inherited IRA allows under the 10-year rule. The account ceases to be an HSA at death and its value is fully taxable that year.
Is there a 20% penalty for non-spousal inherited HSA distributions?
No. The 20% additional tax on non-qualified HSA withdrawals is waived at death for every type of beneficiary. A non-spouse still owes ordinary income tax on the fair market value, but not the 20% penalty. So the cost is income tax at the heir’s marginal bracket, without the extra penalty that would apply during the owner’s life.
Can HSA funds be used to pay medical bills after death?
In a limited way, yes. A non-spouse beneficiary can reduce the taxable inclusion by paying the deceased owner’s qualified medical expenses that were incurred before death, as long as they are paid within 12 months of the date of death. This does not cover the heir’s own medical bills or any expenses incurred after the owner died.
What happens if I forgot to name a beneficiary?
If no beneficiary is on file, the HSA usually passes to your estate, and the fair market value is included on your final income tax return instead of a beneficiary’s. The account still loses its HSA status, and the funds may be delayed by probate. Checking and updating your beneficiary form with the custodian avoids both the estate inclusion and probate.
Does an HSA avoid probate?
Yes, when a beneficiary is named. An HSA with a valid beneficiary designation passes directly to that person outside probate, similar to a retirement account. If no beneficiary is named, the account typically falls into the estate and can be subject to probate. Naming a beneficiary is what keeps the HSA out of the probate process.
Is an HSA a good account to leave to children?
Generally no. A child who inherits an HSA takes the entire fair market value as ordinary income in a single year, with no penalty but no stretch and no rollover. Roth IRAs and taxable brokerage accounts are usually far friendlier for children. For most owners the HSA is better spent down during life or left to a spouse or a charity.
