A CVS receipt has 14 items on it. Three of them are HSA-eligible. The other 11 are not. How do you tell which is which without spending 20 minutes Googling each line?
Most people give up and either reimburse nothing or reimburse everything. Both are wrong. Reimburse nothing and you leave tax-free money on the table. Reimburse everything and you risk a 20% penalty plus income tax if the IRS audits you.
There is a faster way. Four tests, run in order, will tell you what counts on almost any receipt. Then a quick retailer cheat sheet covers the four stores where 80% of HSA-eligible purchases happen.
The 4 Quick Tests
Run a receipt line through these in order. Stop at the first "yes."
Test 1: Is it for medical care?
The IRS defines a medical expense as a cost for "diagnosis, cure, mitigation, treatment, or prevention of disease." That language comes straight from IRS Publication 502, revised for 2025.
A bottle of ibuprofen for a headache passes. A bag of chips does not. A blood pressure monitor passes. A bottle of shampoo does not.
The phrase "primarily to alleviate or prevent" is the test. If the item is "merely beneficial to general health," it fails.
Test 2: Would a doctor write a Letter of Medical Necessity?
Some items are dual-use. A treadmill could be exercise equipment or it could be cardiac rehab. A massage could be a spa day or it could be treatment for chronic back pain.
If a doctor would write a Letter of Medical Necessity for the item, it can qualify. The LMN turns a dual-use product into a documented medical expense. Keep the LMN with the receipt. No LMN, no eligibility for dual-use items.
See the full process in our Letter of Medical Necessity guide.
Test 3: Is it on the IRS-published eligible list?
Publication 502 lists hundreds of qualifying expenses by name. Acupuncture, ambulance, bandages, breast pumps, contact lenses, hearing aids, insulin, prescription drugs, wheelchairs. The list is long but not exhaustive.
Our master HSA-eligible expenses list cross-references Publication 502 with the post-CARES Act updates. Pub 502 still does not fully reflect those updates.
Test 4: Does the receipt itself flag it?
Major retailers now mark HSA and FSA-eligible items directly on the receipt. CVS, Walgreens, Target, and Amazon all use some form of indicator. If the retailer flagged it, you have a built-in audit trail.
The catch: retailer flagging is not perfect. Some stores overflag. Some underflag. Always sanity-check with Tests 1 through 3.
Retailer Quick Reference
Here is how each major retailer marks eligible items. Deep dives linked where available.
| Retailer | How Eligible Items Are Marked | Deep Dive |
|---|---|---|
| CVS | "F" prefix on each eligible line. "FSA SUMMARY" total at the bottom. Available on printed and digital receipts. | CVS receipt guide |
| Walgreens | FSA flag to the left of the line item. "TOTAL FSA ITEMS" summary at the bottom. | Walgreens receipt guide |
| Target | "F" or "FSA" indicator on the printed receipt and in the Target app order history. | Coming soon |
| Amazon | "FSA or HSA eligible" tag under each item on the product page and in Order Details. Summary box on the order page totals eligible items. | Amazon HSA guide |
The pattern across all four: a per-item flag plus a summary total. If a receipt shows the summary total, that is your fastest answer.
The 8 Tricky Categories
These are the categories where eligibility breaks intuition. Most reimbursement mistakes happen here.
1. Vitamins and supplements
Generally NOT eligible. Publication 502 specifically excludes "nutritional supplements, vitamins, herbal supplements" when taken for general health.
Exception: a doctor recommends them as treatment for a specific diagnosed condition. Prenatal vitamins during pregnancy, vitamin D for diagnosed deficiency, iron for diagnosed anemia. Requires LMN documentation.
2. Sunscreen
YES, SPF 15 or higher with "broad spectrum" labeling. The IRS treats sunscreen as preventive care against skin cancer and UV damage.
Lower SPF or tanning products do not qualify. Lip balm with SPF 15+ does.
3. OTC medications
YES, post-CARES Act. The CARES Act of 2020 removed the prescription requirement for over-the-counter drugs.
Tylenol, Advil, Allegra, Pepcid, Nyquil, Monistat, Prilosec OTC. All eligible without a prescription as of January 1, 2020. This applies to HSAs, FSAs, and HRAs. See our CARES Act OTC explainer for the full list.
Note: Publication 502 still says OTC drugs without prescription are not deductible for the itemized medical deduction. The HSA rules are different. Pub 502 is the eligibility list, but HSA OTC rules come from the CARES Act, not Pub 502.
4. Gym memberships
NOT eligible by default. Publication 502 is explicit: "health club dues" do not qualify.
Exception: a doctor prescribes specific exercise for a diagnosed condition like obesity, hypertension, or cardiac rehab. Requires LMN. Even then, only the medical portion may qualify, not general fitness use.
5. Massage therapy
Depends on the diagnosis. A massage for stress relief or general wellness does not qualify. A massage for documented chronic back pain, post-surgery recovery, or fibromyalgia can qualify.
LMN required. Keep the prescription and the receipt together.
6. Special diet foods
Partially eligible. You can claim the cost difference between the special food and the standard version.
Gluten-free bread that costs $7 versus regular bread that costs $3 means $4 is HSA-eligible per loaf. Requires a diagnosed condition (celiac, in this case) and physician documentation. See HSA myths and what is NOT eligible for more partial-eligibility cases.
7. Electric toothbrushes and waterpiks
Usually NOT eligible. Standard dental hygiene is general health, not medical treatment.
Exception: prescribed for diagnosed periodontal disease or orthodontic care. LMN required. The receipt alone does not make it eligible.
8. Cosmetic items
NOT eligible. Botox for wrinkles, teeth whitening, hair removal, cosmetic surgery.
Exception: reconstructive surgery after an accident, disease, or birth defect qualifies. Botox prescribed for chronic migraines or hyperhidrosis qualifies with LMN. The test is whether the item treats a medical condition or improves appearance.
When You Are Not Sure
Save the receipt anyway. Storage is cheap. Penalties are not.
Mark borderline items as "needs review" rather than guessing. If the item is dual-use, ask your provider for an LMN at your next visit. The LMN does not have to be obtained at the time of purchase. It just needs to exist before you claim the expense.
If you reimburse yourself and later find the item was not eligible, repay the HSA before the tax-filing deadline. That avoids the 20% penalty. Document everything.
Common Receipt Types and What to Save
Different receipts need different levels of detail. Here is what to keep.
| Receipt Type | What to Save | Why |
|---|---|---|
| Pharmacy (prescription) | Full receipt with Rx number, drug name, date | IRS wants to see the prescription detail, not just a dollar amount |
| Hospital or ER | Itemized bill plus the EOB | The bill shows charges, the EOB shows what insurance covered |
| Explanation of Benefits (EOB) | Save with the matching provider bill | The EOB is your proof of out-of-pocket cost |
| Dental | Itemized statement with procedure codes | Cleanings and fillings qualify, cosmetic whitening does not |
| Vision | Receipt for exam, glasses, contacts, surgery | All qualify. LASIK qualifies in full |
| Online order (Amazon, etc.) | Order detail page showing FSA/HSA tag | The product page is your eligibility proof |
The rule: keep enough detail to prove what was purchased and that it was medical. A credit card statement showing "CVS $47.83" is not enough. The itemized receipt is.
For tax filing, you report HSA distributions on Form 8889. You do not submit receipts with the form. You keep receipts in case of audit. The IRS recommends keeping them for at least three years after the tax return is filed. Keep them longer for distributions tied to prior-year expenses.
How Tripl Catches This For You
Tripl's receipt parser reads every line item, the retailer's FSA flag, and the summary totals at the bottom. It auto-categorizes the expense. Prescription, OTC med, sunscreen, dental, vision, durable equipment. Then it pulls the eligible dollar amount the retailer printed.
Items the parser is sure about get marked eligible or ineligible automatically. Items in the gray area get flagged "needs review" so you decide once and move on. The receipt image stays attached to the record for audit defense.
No more reading 30 receipts at year-end. No more re-googling "is electric toothbrush HSA eligible" for the fifth time. Snap, forward, or upload a receipt and Tripl handles the rest.
