You can use your HSA for your parents’ medical expenses tax-free if you provide more than half of their total support for the year. The HSA rules treat a parent as your dependent under a looser definition than the one on the front of your tax return: the usual gross income cap and joint-return restriction are waived, so a parent with Social Security, a pension, or part-time wages can still qualify. The support test is the one that actually decides it.
Why the HSA Dependent Rule Is Looser Than the Regular One
The HSA statute borrows the definition of “dependent” from Section 152 of the Internal Revenue Code, then strips away several of the usual restrictions. For HSA distribution purposes, you ignore the gross income test, the joint return test, and the citizenship or residency requirement.1Office of the Law Revision Counsel. 26 U.S. Code 223 – Health Savings Accounts IRS Publication 969 says the same thing in plainer language: qualified medical expenses include costs for any person you could have claimed as a dependent except for the fact that they filed a joint return, had gross income above the threshold, or you yourself could be claimed on someone else’s return.2Internal Revenue Service. Publication 969 – Health Savings Accounts and Other Tax-Favored Health Plans
That difference matters. Under the standard dependent rules, a parent’s Social Security check, pension, or part-time earnings could disqualify them. Under the HSA definition, none of that matters. A parent earning $40,000 a year can still be your HSA-eligible dependent as long as you provide more than half their total support.
Parents are also listed relatives under Section 152, so they don’t have to live with you. A parent in another state or in an assisted living facility still qualifies if you meet the support test.3Office of the Law Revision Counsel. 26 U.S. Code 152 – Dependent Defined
The Support Test
Since the relationship test is automatic for parents and the other tests are waived, the support test is where eligibility is won or lost. You must provide more than 50% of your parent’s total support for the calendar year. Support includes housing costs (rent, mortgage, property taxes, utilities), food, clothing, medical and dental care, transportation, and recreation.4Internal Revenue Service. Dependents
The IRS looks at the total cost of supporting your parent, not just what you pay directly. If your parent lives in a home you own rent-free, the fair market rental value of that housing counts toward what you contribute. If you pay their Medicare premiums, supplemental insurance, and out-of-pocket medical bills, all of it stacks up. Compare your total contributions against everything your parent spends or receives from every source, including their own Social Security, savings withdrawals, and money from siblings.
The math trips people up when a parent has significant Social Security income or retirement distributions. Even though those amounts don’t count against your parent under the gross income test (which is waived anyway), they do count as self-support when you’re calculating whether you provide more than half. If your parent receives $30,000 in Social Security and uses it to pay their own living expenses, you’d need to contribute more than $30,000 in additional support to clear the 50% bar.
When Siblings Share the Cost
Families often split the cost of caring for an aging parent among multiple children. If no single sibling provides more than half, a multiple support agreement under Section 152(d)(3) may help. Any sibling who individually contributes more than 10% of the parent’s support can be designated as the one treated as providing over half, as long as the group collectively provides more than 50%. Only one sibling per year can be designated, and only that person can use their HSA for the parent’s medical expenses tax-free.
What Counts as a Qualified Medical Expense
Confirming your parent qualifies as a dependent is only half the equation. Every expense you pay from your HSA must also meet the IRS definition of “medical care” under Section 213(d): costs for diagnosing, treating, or preventing disease, and expenses that affect a structure or function of the body.5Office of the Law Revision Counsel. 26 U.S. Code 213 – Medical, Dental, Etc., Expenses
Common qualified expenses include doctor visits, hospital bills, lab work, prescription drugs, dental cleanings and procedures, eyeglasses, hearing aids, and mental health treatment. Transportation costs that are primarily for medical care, such as mileage to a doctor’s office or airfare to a specialist, count too.
Nursing Home and Assisted Living
If your parent lives in a nursing home and the primary reason for being there is medical care, the entire cost, including room and board, qualifies. Assisted living is trickier. General housing costs like rent and meals at an assisted living facility typically do not qualify, but the portion attributable to medical or nursing care does. If your parent meets the IRS definition of chronically ill, meaning a licensed health care provider has certified they need help with at least two activities of daily living, or they require substantial supervision due to cognitive impairment, more of their assisted living expenses become eligible.
Long-Term Care Insurance Premiums
Premiums for a qualified long-term care insurance policy are eligible, but only up to age-based limits the IRS adjusts annually.
Regular Health Insurance Premiums
Paying a parent’s regular health insurance premiums from your HSA is not allowed and triggers the same tax and penalty consequences as any other non-qualified withdrawal. The statute permits only a few narrow premium categories: COBRA continuation coverage, long-term care insurance within the age limits, and health plan premiums while receiving unemployment compensation.1Office of the Law Revision Counsel. 26 U.S. Code 223 – Health Savings Accounts
Expenses That Never Qualify
Cosmetic procedures don’t qualify unless they correct a deformity from a congenital condition, accident, or disease. General-purpose vitamins and supplements are excluded. A gym membership or weight-loss program only qualifies if a physician prescribes it to treat a specific diagnosed condition.
What Happens If Your Parent Doesn’t Qualify
If your parent fails the support test, any HSA money you spend on their care is treated as a non-qualified distribution. Two layers of tax follow. First, the entire amount is added to your taxable income for the year and taxed at your ordinary rate, up to 37% at the top federal bracket in 2026.6Internal Revenue Service. Federal Income Tax Rates and Brackets
Second, if you’re under 65, the IRS adds a 20% penalty tax on top of the income tax. A $5,000 non-qualified distribution for someone in the 24% bracket would generate $1,200 in income tax plus a $1,000 penalty, so $2,200 lost on money that was supposed to be tax-free.1Office of the Law Revision Counsel. 26 U.S. Code 223 – Health Savings Accounts
The 20% penalty disappears once you turn 65, become disabled, or in the event of death. After 65, non-qualified distributions are still taxed as ordinary income, but without the extra penalty. Your HSA essentially works like a traditional IRA at that point.1Office of the Law Revision Counsel. 26 U.S. Code 223 – Health Savings Accounts
You report all HSA distributions on Form 8889, which you file with your tax return. Part II of the form calculates taxable distributions and the 20% additional tax on line 17b.7Internal Revenue Service. Form 8889 – Health Savings Accounts
Other Ways to Help a Parent With Medical Costs
When the support test is out of reach, you still have options.
Gift the Money Instead
Rather than pulling from your HSA, give your parent cash to pay their own medical bills. For 2026, you can gift up to $19,000 per person per year without triggering any gift tax reporting requirements. Married couples can give $38,000 combined to a single recipient.8Internal Revenue Service. Frequently Asked Questions on Gift Taxes Your parent then pays from their own account and may be able to claim a medical expense deduction on their own return if they itemize.
Your Parent’s Own HSA
If your parent is covered by a high-deductible health plan and isn’t claimed as anyone’s dependent, they can open and fund their own HSA. For 2026, the contribution limit is $4,400 for self-only coverage or $8,750 for family coverage, and anyone 55 or older can add an extra $1,000 catch-up contribution.9Internal Revenue Service. Revenue Procedure 2025-19 There is a hard stop: once your parent enrolls in any part of Medicare, they can no longer contribute to an HSA. They can still spend existing HSA funds on qualified expenses, but new contributions end the month Medicare coverage begins.
Claiming Their Medical Costs on Your Tax Return
Separately from the HSA question, you may be able to deduct your parent’s medical expenses on your own Schedule A as an itemized deduction. The medical expense deduction uses a slightly broader version of the dependent test: nontaxable Social Security benefits don’t count toward the gross income threshold, which makes more parents eligible. The deduction applies to unreimbursed medical expenses that exceed 7.5% of your adjusted gross income.10Internal Revenue Service. Topic No. 502, Medical and Dental Expenses Between a relatively high standard deduction and the 7.5% AGI floor, this deduction only helps if your combined medical costs are substantial. In years with major expenses like surgery or a nursing home stay, it can produce meaningful tax relief.
