Penalty for HSA Withdrawal: 20% Cost, Exceptions, and Reporting

The penalty for an HSA withdrawal used on anything other than a qualified medical expense is a 20% additional tax, charged on top of the regular income tax you’ll already owe on that money.¹ For someone in the 24% federal bracket, that combination costs 44 cents on the dollar. The 20% penalty disappears once you turn 65, become disabled, or die, though ordinary income tax still applies to non-medical use.

What the 20% Penalty Actually Costs

Two things happen when you pull HSA money and don’t spend it on qualified care. The non-qualified amount is added to your gross income for the year, taxed at your marginal rate, just like wages.² On top of that, the IRS applies a 20% additional tax on the same amount.¹

The math gets painful quickly. Take $5,000 out for a non-medical reason while you’re in the 22% bracket, and you’ll owe $1,100 in income tax plus a $1,000 penalty. That’s $2,100 gone from a $5,000 withdrawal. In the 32% bracket, the same withdrawal costs $2,600. Depending on income, the effective rate on a non-qualified distribution runs from roughly 30% to over 50%.

A mixed withdrawal is treated proportionally. If you pull $6,000 and can document $2,500 in qualified medical expenses, only the remaining $3,500 is subject to income tax and the 20% penalty. That makes it worth the paperwork to separate the two even when a single transaction covers both.

When the 20% Penalty Doesn’t Apply

Three circumstances remove the 20% penalty, even when the money isn’t spent on medical care.¹

You turn 65. From that point on, your HSA functions much like a traditional IRA for non-medical spending: income tax still applies, but the extra 20% is gone.
You become disabled. A physical or mental condition that prevents substantial work activity waives the penalty on distributions. Keep physician documentation.
You die. The penalty doesn’t apply to post-death distributions, though what happens next depends on who inherits the account; a surviving spouse can treat it as their own HSA, while anyone else triggers immediate taxation of the full balance as ordinary income.

Each of these waives only the 20% add-on. Any dollar not spent on qualified medical expenses is still taxed as ordinary income.

What Counts as a Qualified Medical Expense

You can withdraw HSA funds at any time for any purpose; the tax treatment is driven entirely by how the money is used. Qualified medical expenses come out tax-free and penalty-free. The IRS defines them broadly as costs for the diagnosis, treatment, prevention, or cure of disease, and treatments affecting any structure or function of the body.³ Deductibles, copays, prescriptions, dental and vision care, and mental health treatment all fit.

A few recurring trip-wires:

Cosmetic procedures generally don’t qualify.
Most over-the-counter supplements don’t qualify.
Most insurance premiums don’t qualify. The exceptions are long-term care insurance (subject to age-based limits), COBRA, coverage while receiving unemployment, and Medicare Part B, Part D, and Medicare Advantage premiums at age 65 and up. Medigap premiums are specifically excluded.⁴

Two timing rules decide whether an expense qualifies at all. An expense counts only if it was incurred after your HSA was established.⁴ Bills from before you opened the account can never be reimbursed tax-free. There’s no deadline on the other end, though. You can pay a $5,000 medical bill out of pocket today, let the HSA grow for ten years, and then reimburse yourself tax-free, as long as you’ve kept the receipt.

Your custodian doesn’t police what you spend distributions on. That’s your job. If the IRS asks, you need records showing each withdrawal matched a qualifying expense.

Returning a Mistaken Withdrawal

If you take a non-qualified distribution by accident, you may be able to put the money back and avoid the penalty. The IRS allows repayment of a distribution made due to a “mistake of fact due to reasonable cause,” with a deadline of April 15 of the year after you first knew, or should have known, about the mistake.⁵ When the custodian accepts the return, the distribution shouldn’t appear on your Form 1099-SA.

This isn’t a general refund right. The agency expects a real mistake, not a reconsidered spending decision. A debit card misfire or a withdrawal based on a billing statement later corrected is the kind of situation it’s built for. Pulling cash to buy furniture and returning it after reading about the penalty is not.

A Mistake That Can Destroy the Whole Account

A prohibited transaction is in a different category from a non-qualified withdrawal. Using your HSA as collateral for a loan, or engaging in self-dealing with the account, can disqualify the HSA entirely. The account is treated as ceasing to exist on January 1 of the year the prohibited transaction happened, and the full balance is treated as a distribution.⁶ The whole balance hits your income, and the 20% penalty applies to all of it in one year. On a $30,000 account, that can easily exceed $15,000 in combined tax and penalty.

Routine use won’t put you here. The risk comes from treating the HSA as a general-purpose asset to borrow against or transact with. Keep activity to contributions, investments inside the account, and distributions for expenses.

How the Penalty Gets Reported

Your custodian sends Form 1099-SA for any year with a distribution. Box 1 shows the gross amount; the custodian can’t tell qualified from non-qualified use, so nothing is broken out.⁷

You separate the two yourself on Form 8889, filed with your 1040.¹ Part II handles the calculation:

Line 14a: total distributions, matching Box 1 of the 1099-SA.
Line 14b: rollovers to another HSA or timely-returned excess contributions, which aren’t taxable.
Line 15: the amount spent on qualified medical expenses.
Line 16: the taxable portion (14a minus 14b minus 15), added to income.
Line 17a: the box to check if an exception applies (age 65, disability, or death).
Line 17b: the 20% additional tax, calculated on any taxable amount from Line 16 not covered by an exception.

Form 8889 is required any year you take a distribution, even if every dollar was qualified.¹ Skipping it or understating the non-qualified portion can bring an audit, back tax, the 20% penalty, and interest.

State Tax Is a Separate Question

Everything above is federal. Most states follow federal rules and treat qualified distributions as state-tax-free too. A small number of states don’t recognize the HSA tax benefits at all; in those states, contributions are taxed as income, earnings inside the account are taxed annually, and distributions don’t get federal-style treatment. If you live in one of them, add the state cost to the calculation before you decide whether a non-qualified withdrawal is worth taking.
