The penalty for an HSA withdrawal used on anything other than a qualified medical expense is a 20% additional tax on the non-qualified amount, on top of regular income tax at your marginal rate.1Internal Revenue Service. Instructions for Form 8889 For someone in the 24% federal bracket, that combination costs 44 cents on every dollar. The 20% penalty disappears once you turn 65, become disabled, or die, but the income tax on non-medical use still applies.
How the 20% Penalty Is Calculated
Two things happen when you pull HSA money out for a non-qualified reason. The withdrawal gets added to your gross income for the year, taxed like wages at your marginal rate.2Office of the Law Revision Counsel. 26 U.S. Code 223 – Health Savings Accounts Then the IRS adds a separate 20% penalty tax on that same amount.
The math surprises people. Withdraw $5,000 for a non-medical purpose in the 22% bracket, and you owe $1,100 in income tax plus a $1,000 penalty. That’s $2,100 gone from a $5,000 withdrawal. At the 32% bracket, the same $5,000 costs you $2,600. Effective rates on non-qualified HSA distributions land somewhere between 30% and over 50%, depending on income.
The penalty applies only to the non-qualified portion of a withdrawal, not the whole thing. If you pull $6,000 and can document $2,500 of qualifying medical spending, only the remaining $3,500 is taxed and penalized. Careful recordkeeping pays off even on mixed withdrawals.
When the 20% Penalty Doesn’t Apply
Three exceptions waive the additional 20% tax, though ordinary income tax still applies on any non-medical use.1Internal Revenue Service. Instructions for Form 8889
- You reach age 65. Non-medical withdrawals still count as ordinary income, but no penalty is added. From that point on, the HSA behaves much like a traditional IRA for non-medical spending.
- You become disabled. If a physical or mental condition prevents you from engaging in any substantial work activity, the penalty is waived on distributions. Expect to need physician documentation.
- You die. The penalty doesn’t apply to distributions after the account holder’s death.
These exceptions only remove the extra 20%. If the money isn’t spent on a qualified medical expense, it’s still taxable income in the year of the distribution.
What Counts as a Qualified Medical Expense
The cleanest way to avoid the penalty is to keep withdrawals inside the qualified-expense line. The IRS defines qualified medical expenses broadly as costs for the diagnosis, treatment, prevention, or cure of disease, along with treatments affecting any structure or function of the body.3Internal Revenue Service. Topic No. 502, Medical and Dental Expenses Deductibles, copays, prescriptions, dental work, vision care, and mental health treatment are all in.
Common categories that don’t qualify: cosmetic procedures, most over-the-counter supplements, and most health insurance premiums. The premium rule has real exceptions worth knowing. HSA funds can pay for long-term care insurance (subject to age-based limits), COBRA continuation coverage, health insurance during unemployment, and Medicare premiums once you’re 65.4Internal Revenue Service. Publication 969 – Health Savings Accounts and Other Tax-Favored Health Plans The Medicare exception covers Part B, Part D, and Medicare Advantage premiums, but not Medigap.
Timing rules matter too. An expense only qualifies for tax-free reimbursement if you incurred it after your HSA was established. Bills predating the account never qualify. On the other hand, there’s no deadline for reimbursing yourself: you can pay a medical bill out of pocket now, let the HSA grow for years, and take a tax-free distribution later. That works only if you still have the original receipt, so keep bills and explanation-of-benefits statements indefinitely.
Your custodian doesn’t verify what you spend distributions on. If you’re audited, the burden is on you to prove each withdrawal covered a qualifying expense.
Fixing a Mistaken Withdrawal
If you accidentally take a non-qualified distribution, you may be able to return the money and skip the penalty. The IRS allows repayment of distributions made because of a “mistake of fact due to reasonable cause.” The deadline is April 15 of the year after you first knew or should have known the distribution was a mistake.5Internal Revenue Service. Link and Learn Taxes – Distributions From an HSA When a custodian accepts the repayment, the distribution shouldn’t appear on your Form 1099-SA at all.
This isn’t a change-your-mind provision. The IRS expects a genuine mistake, not regret about a spending choice. A debit card that processed a non-medical purchase by accident, or a withdrawal based on a billing statement that was later corrected, is the sort of situation this rule is meant for. Withdrawing cash to buy furniture and returning it three months later because you learned about the penalty likely won’t fly.
Prohibited Transactions: The Worst-Case Scenario
The 20% penalty is painful. A prohibited transaction is worse. Using your HSA as collateral for a loan, or engaging in certain self-dealing transactions, can disqualify the entire account. When that happens, the HSA ceases to exist as of January 1 of the year the prohibited transaction occurred, and the full balance is treated as a distribution.6Office of the Law Revision Counsel. 26 U.S. Code 4975 – Tax on Prohibited Transactions The whole balance gets added to your income and hit with the 20% penalty in one year. On a $30,000 balance, the combined bill can easily top $15,000.
Normal use won’t produce a prohibited transaction. The risk shows up when people get creative, such as pledging the account as security for a margin loan or lending themselves money. Keep the account limited to contributions, investments held inside it, and distributions for expenses.
Reporting the Withdrawal on Your Tax Return
Your HSA custodian sends you Form 1099-SA showing total distributions in Box 1. The custodian doesn’t know how you spent the money, so the form reports gross amounts without splitting qualified from non-qualified.7Internal Revenue Service. Instructions for Forms 1099-SA and 5498-SA
You handle the split on IRS Form 8889, filed with your Form 1040.1Internal Revenue Service. Instructions for Form 8889 Part II asks for total distributions, then how much went to qualified medical expenses, and the difference becomes the taxable amount. The 20% additional tax is calculated on that taxable amount unless you check the box indicating an exception applies (age 65, disability, or death).
If you took any HSA distribution during the year, Form 8889 is required, even if every dollar went to qualified medical care. Skipping it, or understating the non-qualified amount, can trigger an audit, an assessment of the unpaid tax and 20% penalty, and interest on both.
A Note on State Taxes
Everything above is federal. Most states follow the federal treatment, so qualified distributions are also free of state tax. A small number of states don’t recognize the federal HSA tax benefits at all. In those states, contributions are taxed at the state level, earnings inside the account are taxed annually, and distributions don’t receive the federal treatment. If you live in one of those states, add the state tax cost into any withdrawal decision.
