How Is an Inherited HSA Taxed to a Non-Spouse? (w/Examples) + FAQs

This article reflects federal rules as of June 2026 and covers tax year 2025 (filed in 2026). State conformity is addressed in its own section. Tax law changes — confirm current figures before you file.

Quick Answer

The full fair market value of the HSA becomes taxable income to a non-spouse beneficiary in the year the original owner dies. For 2025 deaths, the account stops being an HSA on the date of death, the entire balance is reported as ordinary income, and only qualified medical expenses the decedent owed (paid within one year) reduce that taxable amount.

A Death Benefit That Comes With a Tax Bill

When a non-spouse inherits a Health Savings Account, the account loses its tax shelter the moment the owner dies. The balance does not roll over, it cannot stay invested as an HSA, and it does not get a step-up in basis like a house or a brokerage account. Instead, the entire value lands on the beneficiary’s tax return as ordinary income for the year of death — and a large balance can push that heir into a much higher tax bracket in a single year.

The stakes are rising fast. HSA assets reached a record $147 billion across 39 million accounts by the end of 2024, and many savers now treat HSAs as a stealth retirement fund they never spend down. That means more accounts are passing to adult children and other heirs who have no idea a five- or six-figure tax hit is coming. Timing matters too: the income is taxed in the year of death, and the only relief — paying the decedent’s medical bills — expires one year after the date of death.

Why a Non-Spouse Inherits So Differently From a Spouse

The single most important fact in this entire topic is the identity of the beneficiary. Under Internal Revenue Code Section 223(f)(8), an HSA is treated one of three ways at death, and the gap between the options is enormous.

A spouse beneficiary gets the best deal in the tax code. The HSA simply becomes the surviving spouse’s own HSA, with no tax due, and they can keep using it for qualified medical expenses tax-free for the rest of their life. Nothing is reported as income.

A non-spouse beneficiary — an adult child, grandchild, sibling, parent, friend, or partner — gets the opposite treatment. The account ceases to be an HSA on the date of death. Its fair market value on that date becomes taxable income to the beneficiary, reported on the beneficiary’s own return for the year the owner died. The 20% penalty that normally hits non-medical HSA withdrawals does not apply at death, but the ordinary income tax does.

If the estate is the beneficiary (or no beneficiary was named), the fair market value is included on the decedent’s final income tax return instead of any heir’s return. This is a separate path with its own consequences, covered below.

What “Fair Market Value” Means and When It Is Measured

The taxable number is the fair market value (FMV) of the HSA on the date the owner dies, not the date the money is paid out and not the original contributions.

The HSA custodian (the bank or brokerage holding the account) reports this amount to the beneficiary and the IRS on Form 1099-SA, using distribution code 6 in Box 3 to flag a death distribution to a non-spouse. The consequence of ignoring this form is steep: the IRS receives a copy, so an unreported death distribution is one of the easiest mismatches for an automated notice (a CP2000) to catch, which adds interest and possible accuracy penalties.

A common misconception is that the heir only owes tax on what they actually withdraw, or that leaving the money in the account delays the tax. It does not. The income is locked in at death regardless of when — or whether — the beneficiary takes the cash out. What the reader should do: confirm the date-of-death FMV with the custodian in writing, because that exact figure drives the entire tax bill.

The One-Year Rule That Can Save You Money

There is exactly one lever a non-spouse beneficiary can pull to reduce the taxable amount. The beneficiary may reduce the taxable income by the amount of the decedent’s qualified medical expenses that were unpaid at death — but only if the beneficiary pays those bills within one year of the date of death, per IRS Publication 969.

This is genuinely useful and widely missed. If your late parent died with $6,000 in unpaid hospital, hospice, dental, or prescription bills, and you pay those bills out of the inherited funds within twelve months, you subtract that $6,000 from the taxable amount. The consequence of missing the one-year window is that the deduction is gone forever, and you pay tax on the full balance.

A frequent misconception is that the heir’s own medical bills qualify. They do not — only the decedent’s qualified medical expenses count. What the reader should do: gather every unpaid medical invoice in the deceased’s name immediately, pay them from the inherited money, and keep the receipts and proof of the date-of-death balance for your records.

Which Situation Applies to You?

The right path depends on who you are and how the account was titled. Use this to find your fit.

You are the surviving spouse: The HSA becomes yours, tax-free. Stop here — the non-spouse rules below do not apply to you.
You are an adult child, grandchild, sibling, or friend named as beneficiary: The full FMV is taxable income to you in the year of death. Read the worked examples and the one-year medical-bill section closely.
You are the executor and the estate is the beneficiary (or none was named): The FMV goes on the decedent’s final Form 1040, not on any heir’s return. See the estate section.
You are the HSA owner planning ahead: Your goal is to avoid leaving a tax bomb. See the “What to do next” steps on spending down and naming the right beneficiary.

Three Common Scenarios, Side by Side

Scenario 1: Adult Child Named as Beneficiary

Maria, age 48, is the named beneficiary on her late father’s $40,000 HSA. He died in March 2025. The full $40,000 becomes ordinary income on Maria’s 2025 return.

What Happens to the Account	Tax Result for Maria
Account stops being an HSA on the date of death	$40,000 added to her 2025 ordinary income
She finds $5,000 in unpaid medical bills and pays them within one year	Taxable amount drops to $35,000
No 20% penalty applies at death	She owes only ordinary income tax on $35,000

Scenario 2: The Estate Is the Beneficiary

David’s father never named a beneficiary, so the $25,000 HSA passes to the estate.

What Happens to the Account	Tax Result
FMV goes on the decedent’s final Form 1040	$25,000 taxed on the father’s final 2025 return
Estate distributes leftover cash to heirs	Heirs generally receive after-tax cash, not new taxable income
Final return often sits in a lower bracket	Tax may be lower than dumping it on a high-earning child

Scenario 3: A Six-Figure “Tax Bomb”

Priya, a high earner, inherits her aunt’s $150,000 HSA in 2025 with no unpaid medical bills to offset it.

What Happens to the Account	Tax Result for Priya
Full $150,000 added to her 2025 income	Stacks on top of her salary
Income pushes part of it into the 37% bracket	Tens of thousands in extra federal tax
No spreading allowed (unlike an inherited IRA)	Entire hit lands in one tax year

Worked Numeric Examples

Example A: A Modest HSA to an Adult Child

James inherits a $12,000 HSA from his mother, who died in 2025. James is single and his other taxable income is $60,000, putting his top dollars in the 22% federal bracket for 2025.

HSA fair market value at death: $12,000
Decedent’s unpaid medical bills James pays within one year: $2,000
Taxable inherited amount: $12,000 − $2,000 = $10,000
Federal tax at roughly 22%: $10,000 × 0.22 = $2,200

James keeps $9,800 of the inherited money after federal tax, and the $2,000 he spent on his mother’s bills was never taxed.

Example B: The Six-Figure Tax Bomb

Priya (from Scenario 3) inherits $150,000. She already earns $250,000, so the inherited HSA stacks on top and much of it falls in the 35% and 37% brackets.

HSA fair market value at death: $150,000
Unpaid decedent medical bills: $0
Taxable inherited amount: $150,000
Blended federal tax (roughly 36% across her top brackets): $150,000 × 0.36 ≈ $54,000

Priya nets about $96,000. Had her aunt instead spent the HSA down on her own medical and long-term-care costs while alive, that $54,000 federal hit could have been avoided entirely.

Example C: Comparing to an Inherited IRA

Carlos inherits both a $100,000 HSA and a $100,000 traditional IRA from a non-spouse relative in 2025.

The IRA generally lets him spread withdrawals over the 10-year payout window, softening the yearly tax bite.
The HSA gives no such option — the full $100,000 is taxed in 2025 alone.

This single difference is why advisors call the inherited HSA the harsher of the two accounts for non-spouse heirs.

How an Inherited HSA Compares to an Inherited IRA

Feature	Inherited HSA (Non-Spouse)	Inherited Traditional IRA (Non-Spouse)
When taxed	Full value in year of death	Spread over up to 10 years for most heirs
Penalty at death	No 20% penalty	No 10% early-withdrawal penalty
Way to reduce tax	Pay decedent’s medical bills within 1 year	Time withdrawals across the 10-year window
Stays tax-deferred?	No — account ends at death	Yes — until withdrawn within the window
Step-up in basis	No	No

The takeaway is that an inherited IRA gives an heir room to manage the tax over years, while an inherited HSA collapses the entire tax event into the year of death.

Federal vs. State: Does Your State Tax This Too?

Start with the federal rule: the FMV is federal ordinary income to the non-spouse beneficiary. Then ask the separate question of whether your state taxes it, because state treatment is not automatic.

Most states with an income tax start from federal adjusted gross income or federal taxable income, so the inherited HSA amount usually flows through and is taxed at the state level too. A handful of states — notably California and New Jersey — never recognized HSAs as tax-favored to begin with, which creates its own quirks for residents.

If you live in a no-income-tax state — Florida, Texas, Tennessee, Nevada, Washington, Wyoming, South Dakota, or Alaska — there is no state income tax on the inherited HSA, and the answer is simply “your state does not tax this.” That is a complete and valuable answer, not a gap.

The Forms and Where the Numbers Go

Form 1099-SA — What the Custodian Sends You

The HSA custodian issues Form 1099-SA for the year of death, showing the gross distribution in Box 1 and a distribution code in Box 3. For a non-spouse death distribution, the code is 6. The custodian sends a copy to the IRS, so your return must match it.

Form 8889 — Where the Income Lands for a Non-Spouse

A non-spouse beneficiary reports the taxable death distribution on Form 8889, Part II, reducing it by any of the decedent’s qualified medical expenses paid within one year, then carries the taxable amount to Schedule 1 (Form 1040) as “Other income.” If you are unsure how the parts connect, see a guide on how to fill out Form 8889 before you file. The consequence of skipping Form 8889 is an IRS notice, since the 1099-SA already told them the money moved.

The Decedent’s Final Return — When the Estate Inherits

If the estate is the beneficiary, the FMV is included on the decedent’s final Form 1040, again reduced by qualified medical expenses paid within one year of death. The executor handles this, and Publication 559 covers the final return of a decedent.

Deadlines, Costs, and Timing

Three clocks matter for a non-spouse heir. First, the tax is reported on the return for the year of death, due the following April 15 (April 15, 2026, for a 2025 death). Second, the one-year window to pay the decedent’s medical bills runs from the exact date of death — miss it and the offset vanishes. Third, custodians often require death-distribution paperwork within a set period, sometimes by year-end, so contact them quickly.

On cost, a straightforward inherited-HSA filing is often doable with DIY software for the price of the software. A six-figure balance, an estate as beneficiary, or multiple states usually justifies a CPA or tax attorney, which can run a few hundred to a few thousand dollars but can easily save more than that in avoided mistakes.

Mistakes to Avoid

Assuming the money is tax-free because no penalty applies. The 20% penalty is waived at death, but ordinary income tax still applies to the full balance.
Thinking you only owe tax on what you withdraw. The entire FMV is taxed in the year of death whether or not you take the cash out.
Missing the one-year medical-bill window. Pay the decedent’s unpaid qualified bills within twelve months or lose the only available deduction.
Trying to roll an inherited HSA into your own. Only a spouse can do this; a non-spouse rollover is not allowed and would create extra problems.
Using your own medical expenses to offset the income. Only the decedent’s qualified medical expenses reduce the taxable amount.
Ignoring Form 1099-SA. The IRS gets a copy, and an unreported death distribution triggers an automated notice with interest.
Forgetting the state tax. Many states tax the inherited amount along with the federal return, so plan for both bills.
Letting a high-earning child inherit a large HSA by default. Naming a lower-bracket heir or the estate can sometimes lower the total tax.

Do’s and Don’ts

Do confirm the exact date-of-death fair market value in writing — why: it is the precise number your tax bill is built on.
Do gather and pay the decedent’s unpaid medical bills within one year — why: it is the only legal way to shrink the taxable amount.
Do set aside cash for the tax before spending the inheritance — why: the bill can be tens of thousands of dollars at once.
Do check your state’s treatment — why: most states tax it too, and the state bill surprises people.
Do call a CPA for a six-figure balance — why: bracket and estate planning can save real money.
Don’t assume it works like an inherited IRA — why: there is no 10-year spread, so the full amount hits in one year.
Don’t withdraw slowly to “delay” the tax — why: the tax is set at death regardless of withdrawal timing.
Don’t discard medical invoices in the decedent’s name — why: they may be your only deduction.
Don’t ignore the custodian’s deadline — why: late paperwork can complicate or delay your access to the funds.
Don’t file without Form 8889 — why: omitting it almost guarantees an IRS notice.

Pros and Cons of Being a Non-Spouse HSA Beneficiary

Pro: You receive the full account value as an inheritance — why: even after tax, it is a meaningful windfall.
Pro: No 20% HSA penalty applies at death — why: unlike a living non-medical withdrawal, death distributions skip the penalty.
Pro: Decedent’s medical bills can reduce the tax — why: paying them within a year is a clean, legal offset.
Pro: No probate delay when you are the named beneficiary — why: the account passes directly to you outside the will.
Pro: The cash is liquid and immediately usable — why: you are not locked into a payout schedule.
Con: The entire balance is taxed in one year — why: a large HSA can spike you into a top bracket.
Con: No tax-deferred growth continues — why: the account’s shelter ends at death.
Con: No step-up in basis — why: unlike inherited stock or property, nothing resets to current value.
Con: State tax often piles on — why: most income-tax states follow the federal inclusion.
Con: No way to spread the income — why: unlike an inherited IRA, there is no multi-year window.

What to Do Next

Get the date-of-death balance in writing from the HSA custodian and request the death-distribution forms.
Collect every unpaid medical bill in the decedent’s name and pay the qualified ones within one year of the date of death.
Set aside cash for the tax — estimate it at your top federal bracket plus your state rate before spending the rest.
Report it correctly: non-spouse heirs use Form 8889; an executor reports an estate beneficiary on the decedent’s final Form 1040.
Call a professional if the balance is large, the estate is the beneficiary, or more than one state is involved — that is when a CPA or estate attorney earns their fee.

Frequently Asked Questions

Is an inherited HSA taxable to a non-spouse? Yes. The full fair market value on the date of death is ordinary income to the non-spouse beneficiary for that tax year, reduced only by the decedent’s qualified medical expenses paid within one year of death.

Does a non-spouse pay the 20% HSA penalty? No. The 20% additional tax does not apply to death distributions. The beneficiary still owes ordinary income tax on the full taxable amount, but the penalty is waived.

When is the inherited HSA taxed? In the year the owner dies. The income is locked in on the date of death, regardless of when the beneficiary actually withdraws or spends the money.

Can a non-spouse roll an inherited HSA into their own HSA? No. Only a surviving spouse can treat an inherited HSA as their own. A non-spouse cannot roll it over; the account ends at death.

What reduces the taxable amount for a non-spouse? The decedent’s unpaid qualified medical expenses. If the beneficiary pays those bills within one year of the date of death, that amount is subtracted from the taxable income.

Does my state tax an inherited HSA? Usually yes, if your state has an income tax. Most states start from federal income, so the amount flows through. No-income-tax states like Florida and Texas do not tax it.

What form reports an inherited HSA? Form 8889 for a non-spouse beneficiary. The custodian first issues Form 1099-SA with distribution code 6, and the taxable amount carries to Schedule 1 of Form 1040.

What if no beneficiary was named? The estate inherits it. The fair market value is included on the decedent’s final Form 1040 rather than on any heir’s personal return.

Is an inherited HSA better or worse than an inherited IRA? Worse for tax timing. An inherited IRA can be spread over a 10-year window, while an inherited HSA is fully taxed in the single year of death.

Do I get a step-up in basis on an inherited HSA? No. Unlike inherited stock or real estate, an HSA receives no step-up. Its full date-of-death value is taxed as ordinary income.

Can I use my own medical bills to offset the tax? No. Only the decedent’s qualified medical expenses, paid within one year of death, reduce the taxable amount. Your own medical costs do not count.

How much tax will I owe on a large inherited HSA? It depends on your bracket. Because the full balance stacks on your other income in one year, a six-figure HSA can be taxed largely at the 32%, 35%, or 37% federal rates for 2025.
