Quick answer: HSA qualified expenses are costs the IRS defines as payments for the diagnosis, cure, treatment, or prevention of disease under Publication 502, and that list is much wider than most people assume. Doctor visits, prescriptions, dental work, glasses, therapy, and most over-the-counter medicine and menstrual products all qualify. Cosmetic procedures, general wellness items like vitamins for health maintenance, and most gym memberships do not, and using HSA money on a non-qualified item before age 65 triggers income tax plus a 20% penalty.
What Counts as an HSA Qualified Expense?
An HSA qualified expense is any cost for medical care as defined in IRS Publication 502, which covers the diagnosis, cure, mitigation, treatment, or prevention of disease, or payments affecting a structure or function of the body. That standard is broader than “things a doctor prescribed.” It includes routine dental cleanings, contact lenses, hearing aids, acupuncture, and even certain home modifications made for a medical reason, like a ramp installed after a diagnosis that affects mobility.
The expense also has to be for you, your spouse, or a tax dependent, and it cannot be reimbursed by insurance or any other source. If your insurance pays part of a bill, only the portion you actually paid out of pocket is eligible. Before spending, it helps to understand HSA basics and how the account differs from a flexible spending account, since the two have overlapping but not identical eligible-expense lists.
The Full List of Common HSA Eligible Items
Most people underuse their HSA because they think it only covers big medical bills. In practice, the everyday categories below are all fair game with a valid receipt.
Medical care and provider visits
- Doctor, specialist, and urgent care copays and coinsurance
- Hospital services and surgery, including your deductible portion
- Diagnostic tests, bloodwork, and imaging (X-rays, MRIs, CT scans)
- Physical therapy, occupational therapy, and chiropractic care
- Acupuncture and mental health therapy or counseling
- Prescription medications and insulin
Dental and vision
- Cleanings, fillings, crowns, and orthodontics (braces and clear aligners)
- Eye exams, prescription glasses, contact lenses and solution
- LASIK and other corrective vision surgery
Devices and equipment
- Hearing aids and batteries
- Crutches, wheelchairs, and blood pressure monitors
- CPAP machines and supplies
- Breast pumps and lactation supplies
Mental health and substance use treatment
- Therapy and counseling sessions, including teletherapy platforms billed as medical care
- Psychiatric evaluations and medication management
- Inpatient or outpatient treatment for substance use disorder
- Smoking cessation programs and nicotine replacement products
If an item shows up on a retailer’s “FSA/HSA eligible” shelf tag or in an HSA provider’s eligible-expense tool, it almost always traces back to one of these Publication 502 categories.
Are Over-the-Counter (OTC) Items HSA Eligible?
Yes, most over-the-counter medicine and health products became HSA eligible without a prescription starting in 2020, when the CARES Act permanently removed the old prescription requirement. That single rule change quietly doubled the number of things people can buy with HSA dollars at a pharmacy checkout.
| OTC category | HSA eligible? |
|---|---|
| Pain relievers (ibuprofen, acetaminophen) | Yes, no prescription needed |
| Allergy, cold, and sinus medicine | Yes |
| Menstrual care products (pads, tampons, cups) | Yes, added by the CARES Act |
| Sunscreen (SPF 15+, broad spectrum) | Yes |
| First aid supplies (bandages, antiseptic) | Yes |
| Home COVID and flu test kits | Yes |
| Reading glasses | Yes |
The practical shift is at checkout. Many drugstores now flag eligible items automatically when you pay with an HSA debit card, and inventory feeds from retailers like CVS and Walgreens sync directly with major HSA card networks, so the swipe just works for most OTC purchases.
What HSA Funds Cannot Cover
HSA funds cannot cover expenses that are for general health and appearance rather than treating or preventing a specific medical condition. The IRS draws this line deliberately narrow, and it is the single biggest source of accidental non-qualified withdrawals.
- Cosmetic surgery or procedures not related to a deformity from a congenital condition, accident, or disease
- Teeth whitening
- Vitamins and supplements taken for general health, not a diagnosed deficiency
- Gym memberships and health club dues, unless prescribed for a specific condition with a Letter of Medical Necessity
- Most health insurance premiums (see the exceptions below)
- Non-prescription sunglasses that are not corrective
- Diaper and childcare costs for a healthy baby
A useful gut check: if a doctor would need to write a letter explaining why this specific product treats your specific condition, keep that letter with your receipts. Without it, a gym membership or a weighted blanket is a denial waiting to happen in an audit.
Can You Use HSA Funds for Insurance Premiums?
Generally no, but there are four real exceptions where HSA funds can pay insurance premiums directly, and people miss all four.
| Premium type | HSA eligible? |
|---|---|
| COBRA continuation coverage | Yes |
| Health coverage while collecting unemployment | Yes |
| Medicare Part B, Part D, and Medicare Advantage premiums (after 65) | Yes |
| Qualified long-term care insurance (up to an age-based dollar limit) | Yes, limited |
| Medigap (Medicare supplement) premiums | No |
| Standard employer-sponsored premiums while actively working | No |
| Marketplace or ACA premiums for a plan outside COBRA or unemployment coverage | No |
This is where the account gets genuinely powerful once you stop working. Someone who retires at 63 can pay COBRA premiums straight from the HSA, and once HSA rules on Medicare kick in at 65, Part B and Part D premiums become fair game too, even though new contributions to the account stop once you are enrolled in Medicare.
HSA Eligible Expenses vs FSA: What Is Different
HSA and FSA eligible-expense lists are nearly identical because both follow IRS Publication 502, but the accounts behave differently around that list. An FSA is use-it-or-lose-it each plan year (with a small grace period or carryover some employers offer), while an HSA balance rolls over forever with no deadline to spend it. That difference changes strategy more than eligibility does: FSA holders should spend down aggressively before year-end, while HSA holders can let receipts sit for years and reimburse themselves later, which is the basis of the shoebox strategy below. For the full breakdown, see our HSA vs FSA eligibility differences guide, including who is allowed to have each account type at all.
HSA Debit Card vs Pay-and-Reimburse: Which Should You Use?
Both are legitimate ways to spend HSA funds, and the right choice depends on whether you want to spend the money now or invest it. Swiping the HSA debit card at the point of sale is the simplest option for everyday copays and pharmacy runs. But the more sophisticated move, and the one most HSA providers never explain clearly, is to pay medical bills out of your regular checking account, invest the HSA balance instead, and reimburse yourself years later.
Here is why that works: the IRS lets you reimburse yourself for a qualified expense at any point in the future, with no deadline, as long as the expense happened after the HSA was opened and you kept the receipt. So if you pay a $500 dental bill out of pocket today and let that $500 stay invested in your HSA for 15 years, a modest 7% average annual return turns it into roughly $1,380 tax-free before you ever ask for it back. You are not just deferring a reimbursement, you are compounding tax-free growth on money you were always entitled to withdraw.
This only works if you actually keep the receipts, which is the next problem to solve.
How to Keep Receipts and Records for HSA Withdrawals
Keep every medical receipt indefinitely, not just for the current tax year, because the IRS can ask you to substantiate an HSA withdrawal from any year you are still holding a reimbursement claim against. The “shoebox” is the folk name for this habit: a literal or digital folder where you drop every Explanation of Benefits, pharmacy receipt, and paid invoice the moment it arrives.
- Photograph or scan every receipt the same day you pay, and store copies in at least two places (a labeled email folder plus a cloud drive works fine)
- Note the date, amount, patient name, and what the expense was for directly on the file name
- Keep the Explanation of Benefits (EOB) from your insurer alongside the receipt when insurance covered part of the bill
- Track reimbursed vs. unreimbursed expenses in a simple spreadsheet so you know your running “banked” total
If your current provider charges a monthly maintenance fee just to hold your balance while you are trying to build this kind of long-term reimbursement strategy, that fee quietly erodes the exact compounding this tactic depends on. A no-fee provider like Lively is worth a look if your current account charges monthly upkeep. Here is our full review.
Can You Use HSA Funds for a Spouse or Dependents’ Expenses?
Yes, you can use your HSA to pay qualified medical expenses for your spouse and anyone you claim as a tax dependent, even if they are not covered by your HDHP. This surprises a lot of account holders. The eligibility test is about tax dependency, not insurance enrollment. A parent with family HDHP coverage can use HSA funds for a child’s braces even if that child is on a different insurance plan, as long as the child is still claimed as a dependent on the parent’s tax return.
One nuance: if your dependent turns 26 and ages off your health plan but you can still legally claim them as a tax dependent (uncommon, but possible for a full-time student or someone with a qualifying disability), their expenses may still be eligible. Check dependency status against IRS rules each year, not against your insurer’s coverage cutoff.
What Happens If You Use HSA Funds for a Non-Qualified Expense?
If you spend HSA money on something that is not a qualified medical expense before age 65, the withdrawal is taxed as ordinary income and hit with an additional 20% penalty on top of that. The math gets painful fast. Say you withdraw $2,000 from your HSA to cover a non-medical expense, and you are in the 24% federal tax bracket. You owe $480 in income tax, plus a $400 penalty, for a total of $880 in taxes and penalties on a $2,000 withdrawal, leaving you with $1,120 of actual spending power. That is a worse outcome than just using a regular savings account.
After age 65, that 20% penalty disappears. Non-medical withdrawals are still taxed as ordinary income, but the account effectively converts to behave like a traditional IRA for anything you did not spend on medical care. That is why financial planners increasingly treat the HSA as a stealth retirement account: worst case after 65, it is taxed like a 401(k) withdrawal; best case, every dollar spent on qualified medical expenses (including HSA rules on Medicare premiums) comes out completely tax-free.
| Withdrawal timing | Used for qualified medical expense | Used for non-qualified expense |
|---|---|---|
| Before age 65 | Completely tax-free | Ordinary income tax plus 20% penalty |
| Age 65 and older | Completely tax-free | Ordinary income tax only, no penalty |
That table is the whole reason people say an HSA is the only account that is triple tax-advantaged going in, growing, and coming out, as long as you stay inside the qualified expense list. Miss the list before 65 and you lose the third leg of that advantage.
Do State Taxes Change Which HSA Expenses Qualify?
The federal list of HSA qualified expenses is the same no matter where you live, but a couple of states do not follow federal tax treatment of HSA contributions and growth, which affects your state tax bill even though it does not change what you are allowed to buy. California and New Jersey are the two well-known holdouts: both tax HSA contributions as regular income at the state level and tax investment growth inside the account each year, even though the federal government treats that same money as tax-free. Residents of those two states still get the full federal tax break and still follow the same eligible-expense list everywhere else in this guide, they just owe state tax on contributions and earnings that federal filers in other states do not. If you live in California or New Jersey, plan for a state tax line item on HSA growth and check with a tax professional before assuming your HSA is tax-free at the state level too.
How Contribution Limits Affect What You Can Spend
Your eligible expense list does not change based on how much you have contributed, but knowing the 2026 limits matters for planning how aggressively to bank receipts versus spend as you go. For 2026, the IRS allows $4,400 in HSA contributions for self-only coverage and $8,750 for family coverage, plus a $1,000 catch-up contribution if you are 55 or older. Someone maxing out a family contribution and paying medical bills out of pocket while investing the HSA balance is running the long-game version of this account; someone using it more like a debit account for routine copays is running the short-game version. Both are valid, and the eligible-expense rules are identical either way.
FAQ
Is toothpaste or mouthwash HSA eligible?
No. General oral hygiene products like toothpaste, floss, and mouthwash are considered general health items, not treatment for a specific condition, so they are not HSA eligible even though dental treatment itself is.
Can I use my HSA for my gym membership?
Only with a Letter of Medical Necessity from a doctor tying the membership to treatment of a specific diagnosed condition, such as obesity or a cardiac rehabilitation plan. Without that documentation, gym dues are not qualified.
Are prenatal vitamins HSA eligible?
Yes. Prenatal vitamins are treated differently from general multivitamins because they support a specific, IRS-recognized condition, pregnancy, so they qualify without a prescription.
Can I use HSA funds for my pet’s medical bills?
No, veterinary care for a pet is not a qualified medical expense under Publication 502, even though the same kind of care for a service animal that assists a person with a diagnosed disability can qualify.
Do I need a prescription to buy OTC medicine with my HSA?
No, not since 2020. The CARES Act permanently removed the prescription requirement for over-the-counter drugs and added menstrual care products to the eligible list without a doctor’s note.
What if I accidentally use my HSA card for something non-qualified?
Report it and correct it the same tax year if possible. Some HSA providers let you repay the account directly to reverse the mistake before it is reported as a distribution; if that window passes, it gets taxed as a non-qualified withdrawal on your return, and you should still keep documentation of the error for your tax preparer.
Are health insurance premiums ever HSA eligible?
Only in specific cases: COBRA premiums, premiums while collecting unemployment, Medicare premiums (Part B, Part D, Medicare Advantage) after 65, and limited long-term care insurance premiums. Standard employer or marketplace premiums while actively insured do not qualify.
Can HSA funds pay for LASIK or other elective vision surgery?
Yes, LASIK and other vision-correction surgery are qualified medical expenses even though they are elective, because they correct a diagnosed vision condition rather than altering appearance.
How long do I have to reimburse myself for a qualified expense?
There is no deadline, as long as the expense was incurred after your HSA was established and you keep the receipt. You can pay a medical bill in 2026 and reimburse yourself from the HSA in 2040 if you still have the documentation.
Is adult orthodontia HSA eligible?
Yes. Braces and clear aligners qualify for adults the same way they do for children, since the IRS treats orthodontic treatment as dental care regardless of the patient’s age.
Does my HSA cover a home genetic or DNA test kit?
Only if the test is ordered by a physician for a specific diagnostic purpose. A general ancestry or wellness DNA kit purchased directly from a retailer without a medical reason typically does not qualify.
