Key Takeaways
- You can use HSA funds for your spouse's or tax-dependent children's medical expenses without penalty, but not for adult children, parents, or other family members.

- The IRS defines a tax-dependent as someone you claim on your tax return who lives with you and meets income and relationship tests.
- Your HSA custodian (the bank or administrator) does not police who you pay — the IRS enforces the rules through your tax return.
- Retirees over 65 can withdraw HSA money for anyone's medical expenses without penalty, but still owe income tax on non-may have access to withdrawals.
Who Counts as a may have access to Dependent for HSA Purposes
The IRS allows you to use HSA money for medical expenses of your spouse and your tax-dependent children. A tax-dependent is someone you claim on your federal tax return — typically your children under 19, or under 24 if they are full-time students. If your adult child does not meet the age and income tests to be claimed as a dependent, you cannot use your HSA to pay their medical bills without triggering taxes and penalties.
Parents, siblings, grandchildren, and in-laws do not count, even if you help support them or they live in your home. The IRS is strict about this: the person must be listed on your Form 1040 as a dependent. If you are unsure whether someone qualifies, check your most recent tax return or ask a tax preparer before you spend the HSA money.
What Happens When You Use HSA Money for a Non-Dependent
If you withdraw HSA funds to pay for someone else's medical care and that person is not your spouse or tax-dependent, the IRS treats the withdrawal as a non-may have access to distribution. You owe ordinary income tax on the full amount you withdrew, plus a 20 percent additional penalty. That penalty is separate from the income tax — it is a flat 20 percent on top of whatever your tax bracket is.
Example: You withdraw $2,000 from your HSA to pay your adult daughter's dental work. If you are in the 22 percent tax bracket, you owe $440 in income tax plus $400 in penalty, for a total of $840 in taxes on a $2,000 withdrawal. Your HSA custodian does not stop you from making the withdrawal, but when you file your tax return, you must report it as a non-may have access to distribution on Form 8889, and the IRS will assess the penalty.
How Your HSA Custodian Handles Withdrawals
Your HSA custodian — the bank, insurance company, or third-party administrator holding your account — does not verify who you are paying before you withdraw money. They process the withdrawal based on your request. The IRS does not require custodians to police the purpose of withdrawals or ask for receipts at the time you take the money out.
This means you can withdraw HSA funds and pay anyone you want. The enforcement happens later, on your tax return. When you file Form 8889 (HSA Deduction and Distributions), you report whether each distribution was for a may have access to medical expense. If you report a non-may have access to distribution, you owe the tax and penalty. If you do not report it and the IRS audits you, they will assess the penalty retroactively, plus interest.
The Special Rule for Retirees Over 65
Once you turn 65, the penalty for non-may have access to HSA withdrawals goes away. You can withdraw money from your HSA for any reason — medical or not — and you only owe income tax on the amount, no 20 percent penalty. However, this does not mean you can use HSA money tax-free for someone else's medical bills. You still owe income tax on the withdrawal.
The advantage at 65 is that your HSA becomes more like a traditional IRA: you can use it for anything without penalty, but non-medical withdrawals are taxable. If you withdraw $5,000 for your adult son's surgery at age 67, you owe income tax on that $5,000, but no additional penalty. Many people use this flexibility to spend down their HSA in retirement for any healthcare cost, including long-term care or insurance premiums.
Paying Medical Bills for Your Spouse
Your spouse's medical expenses are always may have access to, regardless of whether you file taxes jointly or separately. You can use your HSA to pay for your spouse's doctor visits, prescriptions, dental work, vision care, mental health treatment, and other medical costs. You do not need to claim your spouse as a dependent — the rule is based on marital status, not tax-dependent status.
If you are divorced or separated, you can no longer use your HSA for your ex-spouse's medical bills. The may have access to status ends when the marriage ends. If you are married but file taxes separately, your spouse still counts as may have access to for HSA purposes, even though you do not claim them as a dependent on your return.
Medical Expenses That may have access to, Regardless of Who Pays
The IRS has a specific list of what counts as a may have access to medical expense. Whether you are paying for yourself, your spouse, or a tax-dependent child, the expense must be on this list. may have access to expenses include doctor and dentist visits, prescription drugs, mental health treatment, physical therapy, hearing aids, glasses and contact lenses, and most medical equipment and supplies.
Non-may have access to expenses include cosmetic surgery (unless it is reconstructive after an injury), gym memberships, vitamins and supplements (unless prescribed by a doctor for a specific condition), and over-the-counter medications (unless prescribed). If you are unsure whether a specific expense qualifies, check IRS Publication 502 or ask your HSA custodian before you withdraw the money.
Frequently Asked Questions
Can I use my HSA to pay my parent's medical bills?
No, unless your parent is claimed as a tax-dependent on your return. If you support your parent and claim them as a dependent, you can use your HSA for their medical expenses. If you do not claim them as a dependent, any HSA withdrawal to pay their medical bills triggers income tax plus a 20 percent penalty.
What if I pay someone else's medical bill and they reimburse me later?
If you withdraw HSA money to pay a non-dependent's medical bill and they pay you back, you still owe taxes and penalties on the original withdrawal. The reimbursement does not change the tax treatment. To avoid this, have the non-dependent pay their own bill directly, or do not use HSA money for their expenses.
Can I use my HSA for my adult child's medical bills if I help support them?
Only if you claim them as a tax-dependent on your return. Helping support someone does not make them a dependent for HSA purposes — they must meet the IRS tests for dependent status, which usually means they are under 19 or under 24 if a full-time student, and their income is below a certain threshold.
Do I have to report HSA withdrawals to the IRS every year?
Yes. Your HSA custodian sends you a Form 1099-SA each year showing all distributions. You report this on Form 8889 when you file your tax return. You must indicate whether each distribution was for may have access to medical expenses. Non-may have access to distributions are subject to income tax and the 20 percent penalty.
What if I made a withdrawal for someone else and did not report it correctly?
Contact a tax professional or the IRS to amend your return. Filing an amended return (Form 1040-X) is better than waiting for an audit. If the IRS discovers unreported non-may have access to distributions, you will owe the tax, the penalty, and interest on top. Amending voluntarily may reduce or eliminate the interest.
