HSA Prohibited Transactions: Rules, Disqualification, and Excise Taxes

HSA prohibited transactions are specific self-dealing arrangements between your Health Savings Account and a “disqualified person” under IRC Section 4975, and the consequences split sharply depending on who committed the violation. If you (the account holder) did it, the HSA loses its tax-exempt status retroactive to January 1 of that year and the entire balance becomes taxable income. If a different disqualified person did it, the account survives but that person owes an excise tax of 15% of the amount involved, rising to 100% if the transaction isn’t unwound.¹

The Four Categories of Prohibited Transactions

IRS Publication 969 identifies four types of dealings between an HSA and a disqualified person that are barred:²

Buying, selling, exchanging, or leasing property between you and the HSA. Selling your personal laptop to the HSA, or leasing office space from it, both qualify.
Lending money between you and the HSA. You cannot borrow from the account or pledge its assets as collateral.
Providing goods, services, or facilities between you and the HSA. Paying yourself to manage its investments is an example.
Transferring HSA assets for your personal benefit outside of paying qualified medical expenses.

The common thread is self-dealing. The rules cover indirect transactions structured to reach the same result, so routing a deal through a controlled entity does not sidestep them.

Who Counts as a Disqualified Person

A prohibited transaction only exists if the HSA is dealing with a disqualified person. The category is broader than most account holders assume:¹

You, the account beneficiary.
Your spouse, parents, grandparents, children, and grandchildren. Siblings, aunts, uncles, and cousins are not included.
Any fiduciary who exercises discretionary control over the HSA or its assets.
Corporations, partnerships, trusts, or estates in which disqualified persons hold 50% or more of the ownership interest.
Officers, directors, or 10%-or-greater owners of an entity that is itself a disqualified person.

If You Commit the Violation: Account Disqualification

When you personally engage in a prohibited transaction, the HSA stops being an HSA as of January 1 of that year, not the date of the transaction.³ A violation in November unravels the account for the whole calendar year. Contributions lose their deduction, distributions lose their tax-free treatment, and every dollar in the account is treated as if it were distributed to you on January 1.

The deemed distribution equals the fair market value of all assets on January 1 and is included in your gross income. On top of ordinary income tax, IRC Section 223(f)(4) imposes an additional 20% tax on the includible amount. Two exceptions apply: the 20% additional tax does not apply if you are age 65 or older, or if you are disabled as defined by the tax code.³

A concrete example. Your HSA held $15,000 on January 1, and you are under 65. You owe ordinary income tax on the full $15,000, plus a $3,000 additional tax. The funds do not physically leave the account, but they lose their shelter. The deemed distribution is reported on Form 8889 with that year’s return.

There is no correction window for the account holder. Unlike the excise-tax track described below, you cannot unwind the transaction and restore the HSA’s status.

If Someone Else Commits the Violation: Excise Taxes

When a disqualified person other than the account beneficiary engages in a prohibited transaction, the HSA keeps its tax-exempt status. The IRS assesses excise taxes on the person who committed the violation:¹

An initial tax of 15% of the amount involved, for each year or partial year in the taxable period.
A 100% tax on the amount involved if the transaction is not corrected before the IRS mails a notice of deficiency.

Correction means reversing the transaction as fully as possible and restoring the HSA to the position it would have been in had the transaction never occurred. The taxable period runs from the date of the transaction through the earlier of the notice of deficiency or the date the tax is assessed. Reporting is on Form 5329.

So a fiduciary or a family member who improperly deals with your HSA faces steep penalties, but the account itself is not destroyed. When the account holder commits the violation, no excise tax applies, but the HSA is gone for tax purposes.

Prohibited Transactions Are Not the Same as Non-Qualified Distributions

This is where most confusion sits. Spending HSA money on a vacation, a television, or medical bills for a non-dependent adult child is not a prohibited transaction. It is a non-qualified distribution: a withdrawal used for something other than a qualified medical expense. Non-qualified distributions are taxable and carry the same 20% additional tax under 65, but the account remains an HSA and remains usable for future qualified expenses.⁴

A prohibited transaction is a structural misuse of the account itself: lending from it, leasing to it, transferring its assets for your personal benefit outside the distribution process. Withdrawing money and spending it on the wrong thing costs you a penalty on that withdrawal. Using the account itself in a barred way costs you the account.

Collectible Investments Are Treated Separately

If your HSA buys a collectible, IRC Section 408(m) treats the purchase price as an immediate distribution. Covered items include artwork, rugs, antiques, gems, stamps, most coins, and alcoholic beverages. The purchase amount becomes taxable income, plus the 20% additional tax if you are under 65.⁵

Narrow exceptions exist for certain U.S.-minted gold, silver, and platinum coins, state-issued coins, and bullion of specified fineness held by a bank or approved trustee. Most HSA custodians limit you to mutual funds, ETFs, and similar instruments, so this trap is mainly a concern with self-directed HSAs that allow broader investments.

Mistaken Distributions Can Be Reversed, Prohibited Transactions Cannot

If you withdrew money from your HSA by mistake, you can return it by the tax return due date (without extensions) for the first year you knew or should have known the distribution was an error. When you meet that deadline, the distribution is not included in income, no 20% additional tax applies, and the repayment does not count against your annual contribution limit.⁶

The custodian is not required to accept the return and may ask for a written statement that the withdrawal was a mistake. If a Form 1099-SA was already filed, a corrected form should be issued.

This relief covers genuine errors, like withdrawing from the wrong account or pulling out more than the bill required. It does not fix prohibited transactions. Putting the money back after you lent yourself HSA funds or leased property to the account does not restore the account’s tax-exempt status.
