What's NOT HSA Eligible: 12 Items That Trigger a Penalty

A 20% Penalty on One Side, $600 in Missed Tax Savings on the Other

The IRS hits non-qualified HSA spending with a 20% penalty plus income tax. Most HSA blog posts cover the eligible side. The ineligible side and the grey-area side cost people more money.

Direction one: you swipe the debit card on something that looks medical but is not. The IRS treats it as a non-qualified distribution. You pay income tax plus a 20% penalty.

Direction two: you skip a $1,500 ergonomic chair because you assume it is not eligible. One doctor's letter would have made it fully tax-free.

Both mistakes come from the same root cause. Most people treat HSA eligibility as a fixed list. It is not. It is a function of medical necessity, documentation, and what you are willing to ask for.

The IRS Rule That Defines HSA Eligibility

The master rule lives in IRC Section 213(d), which defines medical care as amounts paid "for the diagnosis, cure, mitigation, treatment, or prevention of disease." Treasury Regulation 1.213-1(e)(1)(ii) narrows that further: care must be "primarily for the prevention or alleviation of a physical or mental defect or illness."

That regulation does a lot of work. General wellness fails this test. Treatment of a diagnosed condition passes. The same gym membership can be ineligible for one person and eligible for another. The difference is the diagnosis and the documentation.

IRS Publication 502 is the canonical list of medical expenses. It is not exhaustive, but it is the closest thing to an official answer. When you see "consult Pub 502" in HSA content, this is the document.

12 Items That Are NOT HSA Eligible (But People Assume They Are)

Here are the most common items people swipe HSA cards on by mistake. Each one trips up plan holders at tax time.

1. Gym Memberships

General fitness use is not eligible. Even if your doctor says exercise is good for you, that is not enough.

The exception: a Letter of Medical Necessity (LMN) for a diagnosed condition can make the membership eligible. Common qualifying conditions are obesity, hypertension, and type 2 diabetes. General "I want to be healthier" does not qualify.

2. Daily Multivitamins

Standard multivitamins are not HSA-eligible. They fail the "primarily for treatment" test. General wellness does not count.

The recognized exception is prenatal vitamins. The IRS treats those as eligible without a prescription. Other vitamins require a prescription tied to a diagnosed deficiency.

3. Toothpaste, Mouthwash, and Cosmetic Dental Products

General oral hygiene is not medical care. Toothpaste, floss, and mouthwash are personal care, not treatment.

The line gets blurry on the cosmetic side. Whitening strips and cosmetic dental products are clearly out. See HSA dental and vision rules for what dental work does qualify.

4. Cosmetic Procedures

This is the biggest category of mistakes. IRC Section 213(d)(9) excludes cosmetic surgery and similar procedures from medical care, unless the procedure is necessary to ameliorate a deformity arising from a congenital abnormality, an injury from an accident or trauma, or a disfiguring disease.

Not eligible:

• ●Botox for wrinkles
• ●Hair restoration for cosmetic baldness
• ●Breast augmentation for cosmetic reasons
• ●Teeth whitening
• ●Plastic surgery for cosmetic purposes

The exception in the statute itself: cosmetic surgery IS eligible if it is necessary to ameliorate a deformity arising from, or directly related to, a congenital abnormality, a personal injury resulting from an accident or trauma, or a disfiguring disease. Reconstructive surgery after a mastectomy is the classic example. A nose job because you do not like your nose is not.

Botox is a special case. Botox prescribed for a diagnosed medical condition (chronic migraine, severe hyperhidrosis, cervical dystonia, blepharospasm, certain bladder conditions) is eligible as treatment under §213(d), not as cosmetic surgery. Bring the prescription and the diagnosis (typically with an LMN). Botox for wrinkles or other cosmetic use stays excluded.

5. Marriage Counseling

Couples therapy without a medical diagnosis is not eligible. The IRS does not treat relationship counseling as medical care.

Individual mental health therapy IS eligible. See HSA mental health expenses for the full breakdown. The distinction matters at audit time.

6. Diet Food and Weight Loss Programs (For General Wellness)

Weight Watchers, Noom, Jenny Craig. Not eligible if you are using them for general wellness.

They become eligible only with a Letter of Medical Necessity for a diagnosed condition. Obesity, type 2 diabetes, and hypertension are the most common qualifying diagnoses. Even then, only the program fee is eligible. The food itself is generally not.

7. Maternity Clothes

Clothing is clothing. The IRS does not care that it stretches over a pregnant belly. Not eligible.

Same rule applies to nursing clothes and postpartum support garments not prescribed by a doctor. Any "needed because of pregnancy" apparel falls in the same bucket. See the full HSA pregnancy eligible expenses guide for what does qualify.

8. Babysitting and Childcare

Childcare is not a medical expense. Even if you hired the babysitter so you could go to a medical appointment.

The IRS draws a hard line here. Childcare expenses might be eligible for the Dependent Care FSA or the Child and Dependent Care Tax Credit. They are not eligible for an HSA.

9. Health Insurance Premiums (Most of Them)

This one surprises people. Your regular health insurance premiums are not HSA-eligible.

The four exceptions:

• ●COBRA continuation coverage premiums
• ●Medicare Parts A, B, C (Medicare Advantage), and D premiums for the account holder once age 65 or older. Medigap (Medicare Supplement) premiums are NOT eligible. See HSA after 65
• ●Qualified long-term care insurance premiums, up to age-based annual dollar limits set by IRC §213(d)(10) (with 2026 dollar amounts updated by Rev. Proc. 2025-32). The limit increases as the insured ages
• ●Health insurance premiums while receiving unemployment compensation

Marketplace premiums while you are employed? Not eligible.

10. Funeral and Burial Expenses

Funeral, burial, and cremation costs are not medical care under Section 213(d). Not eligible.

This catches people during difficult times. Worth knowing in advance.

11. Doula Services

This is the most ambiguous item on the list. The IRS has not issued formal guidance approving doulas as medical care providers.

Some HSA administrators reimburse doula services with a Letter of Medical Necessity. Many do not. If you plan to use HSA funds for a doula, call your administrator before booking. Get the answer in writing.

I am being honest about the ambiguity. Anyone who tells you doulas are clearly eligible or clearly not eligible is overstating the law. Default treatment in the absence of administrator approval and documentation: not eligible. The risk of an unsupported reimbursement is the 20% penalty plus tax on the distribution if you are under 65.

12. Cord Blood Storage (For General Future Use)

Banking cord blood "just in case" is not eligible. The IRS treats general future-use storage as a personal expense, not medical care.

The IRS has not issued formal published guidance on cord blood storage. Some HSA administrators allow it with documented medical need (a sibling with a diagnosed treatable condition like leukemia, for example); many do not. Without a specific documented medical need, treat it as not eligible.

The Grey Area: Items Eligible with a Letter of Medical Necessity

Here is the part most people do not know exists. A Letter of Medical Necessity from a licensed provider can move many "no" items into the "yes" column.

The LMN works because of the same rule that excludes general wellness. IRC Section 213(d) and Treas. Reg. 1.213-1(e)(1)(ii) require care to be for "prevention or alleviation of a physical or mental defect or illness." When a doctor documents that a specific item treats your specific diagnosed condition, that condition is met.

Items that commonly become eligible with an LMN:

A few of these need extra explanation.

Special diet costs. You cannot expense the full grocery bill. Only the difference between the cost of the special version and the cost of the standard version is eligible. If gluten-free bread costs $7 and regular bread costs $4, you can expense $3. Save the receipts for both.

Hot tub or swimming pool. This sounds aggressive but the IRS has allowed it for diagnosed conditions like arthritis. Under IRS Publication 502 and Treas. Reg. 1.213-1(e)(1)(iii), when a capital improvement also increases the value of your home, the eligible medical expense is the cost of the improvement MINUS the increase in your home's fair market value. If a hot tub costs $8,000 and increases your home's value by $3,000, the eligible amount is $5,000. If the home value increase equals or exceeds the cost, none of it is eligible. You need a real estate appraisal to defend the number, and the medical necessity has to be documented by a physician.

Special education tuition. Revenue Ruling 70-285 set the framework, and Revenue Ruling 78-340 applied it directly to learning disabilities. School tuition for a child with a diagnosed learning disability can be eligible if the school's primary purpose is alleviating the condition, the child has a formal medical diagnosis, and a physician has recommended the school. This is narrow. A regular private school does not qualify just because it has small class sizes.

How to Get a Letter of Medical Necessity for HSA Expenses

The LMN process is simpler than people think. Five steps.

• ● Schedule a doctor visit. Bring the item or service in question. If you want a standing desk for back pain, bring documentation of the desk and your symptoms.

• ● Doctor writes the letter. The letter needs four elements. The medical condition, the recommended treatment, why this specific item treats the condition, and the duration of need. Most doctors have done this before.

• ● Submit to your HSA administrator. Most accept PDFs through their member portal. Some require an attestation form alongside the letter. Check before submitting.

• ● Save the LMN with your records. This is critical. If the IRS audits your HSA distributions, the LMN is your defense. See Form 8889 audit guidance for what records they ask for.

• ● Renew annually if treatment is ongoing. An LMN typically covers 12 months. If you need the item or service longer, get a new letter at your annual physical.

What HSA Eligibility Mistakes Actually Cost You

Here is what the LMN system is worth in real dollars.

A diagnosed back-pain sufferer spends $2,500 on an ergonomic chair, a sit-stand desk, and a lumbar support pillow.

Without an LMN: $0 of that is HSA-eligible. All paid with after-tax dollars.

With an LMN: $2,500 fully tax-free withdrawal from the HSA.

At a 24% federal bracket, that LMN is worth $600 in real tax savings. The doctor visit copay to get the letter might cost $50. Net benefit: $550 on a single conversation with your doctor.

Now run the same math on a $4,000 hot tub for diagnosed arthritis (eligible portion depends on the home value increase). Or $1,200/year in massage therapy for chronic pain. Or special education tuition that runs $15,000/year.

The numbers add up across years. A family that learns the LMN system early can move tens of thousands of lifetime dollars from after-tax to tax-free. See the common HSA mistakes that cost thousands for more patterns to avoid.

The Reframe: HSA Eligibility Is Not a Fixed List

Most HSA content treats eligibility as a fixed list. Look it up, check the box, move on.

That framing misses how the system actually works. Eligibility comes down to three things. The IRS definition of medical care, the documentation you can produce, and whether you ask your doctor for a letter.

The people who get the most out of their HSA are not the ones with the highest balance. They are the ones who understand the LMN process and use it. That is the real edge. The same logic powers the delayed reimbursement strategy: if the receipt is documented and the expense is qualified, the tax-free withdrawal is yours whenever you want it.

If you have not done a receipt audit recently, the mid-year HSA check-in is a good place to start. Swipe your debit card a lot? The HSA debit card opportunity cost guide covers what gets penalized when records are missing.

HSA Not Eligible FAQs

What happens if I use my HSA for something not eligible?

You owe ordinary income tax on the amount plus a 20% penalty if you are under 65. After 65 the penalty disappears but you still owe income tax. The penalty applies even if the mistake was honest.

Can I get an LMN after I already paid for something?

Sometimes. Some administrators accept retroactive LMNs if the condition existed at the time of purchase. The doctor has to confirm the item was treating it. Many administrators refuse. Get the letter first when possible.

Do I need to send the LMN to the IRS?

No. You keep the LMN with your records. You only produce it if the IRS audits your HSA distributions. The audit is what makes the documentation matter.

Are over-the-counter items eligible without an LMN?

OTC drugs are eligible without a prescription under the CARES Act of 2020 (which restored pre-2011 treatment), and menstrual care products were newly added as qualified medical expenses by the same law. General wellness items like daily multivitamins still require a prescription or an LMN tied to a diagnosed deficiency.

Is teeth whitening ever eligible?

No. Teeth whitening is treated as cosmetic regardless of why you want it. Restorative dental work like crowns, fillings, and root canals is eligible.
