Costco HSA Eligible Items and How to Read the Receipt

Costco's pharmacy site now says it accepts FSA and HSA cards "at every register, not just in the pharmacy." Costco's customer service payment page still lists only three counters.

The receipt is a different story. A Costco receipt is itemized. It does not flag what qualifies for an HSA. Walgreens and CVS do that work for you. Costco leaves it to you.

This post covers where the card works and what qualifies. Then how to turn a long Costco receipt into an HSA record. For the chains that mark eligibility on the receipt, see Walgreens and CVS.

Where the HSA Card Works at Costco

As of September 2026, Costco's own pages say two slightly different things.

The Costco Pharmacy site says the cards work "at every register" and "across all departments." The customer service payment page lists FSA/HSA debit cards "at Pharmacies, Optical and Hearing Aid Departments."

Read those together and the practical answer is this:

Counter	HSA card	What you buy there
Pharmacy	Yes	Prescriptions, immunizations, some OTC
Optical	Yes	Prescription glasses, contacts, eye exams
Hearing Aid Center	Yes	Hearing aids, tests, fittings. Costco's page says "FSA and HSA Eligible"
Front registers	Per the pharmacy site, yes	Kirkland OTC medicine, first aid, contact solution, readers
Gas station	Not for HSA purposes	Fuel for a Costco run is not a medical expense

Pharmacy

HSA card: Yes
What you buy there: Prescriptions, immunizations, some OTC

Optical

HSA card: Yes
What you buy there: Prescription glasses, contacts, eye exams

Hearing Aid Center

HSA card: Yes
What you buy there: Hearing aids, tests, fittings. Costco's page says "FSA and HSA Eligible"

Front registers

HSA card: Per the pharmacy site, yes
What you buy there: Kirkland OTC medicine, first aid, contact solution, readers

Gas station

HSA card: Not for HSA purposes
What you buy there: Fuel for a Costco run is not a medical expense

If the front register declines the card, the fallback costs nothing. Pay with a regular card. Keep the receipt. Reimburse yourself from the HSA later. There is no deadline on that reimbursement.

Costco's payment page adds one more line worth knowing. It says Costco cannot identify which items are eligible before the sale goes through. That is the root of the receipt problem below.

The Costco Receipt Problem

A Walgreens receipt prints "TOTAL FSA ITEMS" at the bottom. Amazon prints an "FSA or HSA eligible" line on the invoice. Costco prints neither.

What Costco prints is an itemized list. Each line has a product name and a price. That is enough for an audit. The IRS wants to see what was bought, when, where, and for how much. The Costco receipt has all four.

What it lacks is the sorting. You do that in three steps.

●Find the eligible lines. Kirkland ibuprofen is eligible. The rotisserie chicken is not.
●Add the eligible lines. Include the sales tax on those lines.
●Record that number, not the receipt total.

A $312 Costco run with $41 of allergy medicine and contact solution is a $41 HSA expense. The receipt is the proof. The $41 is the claim.

Circle the eligible lines on the paper before you photograph it. Six months later you will not remember which lines you counted.

What Qualifies at Costco

The rules are the IRS's, not Costco's. Publication 502 is the list.

Item	HSA eligible?	Why
Kirkland OTC medicine (ibuprofen, acetaminophen, allergy, antacid)	Yes	No prescription needed since the CARES Act in 2020
First aid kits, bandages, thermometers	Yes	Medical supplies
Contact lens solution, reading glasses	Yes	Vision care
Prescription glasses and contacts at Costco Optical	Yes	See the [dental and vision post](/blog/hsa-dental-vision-expenses)
Hearing aids at the Hearing Aid Center	Yes	Costco lists them as FSA and HSA eligible
Prescriptions at Costco Pharmacy	Yes	Always qualified
Flu shots and other immunizations at the pharmacy	Yes	Prevention of disease is medical care under IRC §213(d)
Menstrual care products	Yes	Treated as medical care under IRC §223(d)(2)(A)
Blood pressure monitors, pulse oximeters	Yes	Diagnostic devices
Kirkland vitamins, fish oil, probiotics	No	Pub 502 excludes supplements without a practitioner's recommendation for a diagnosed condition
Protein powder, electrolyte drinks	No	General health, not medical care
Toothpaste, floss, mouthwash	No	Personal-use items
The membership fee	No	Not a medical expense
Groceries, paper towels, the hot dog	No	Not medical care

The vitamin aisle is the trap. Costco supplements do not qualify on their own. A Letter of Medical Necessity from a doctor changes that for a specific product tied to a diagnosed condition. Without the letter, leave the vitamins off the claim.

Costco.com and Costco Same-Day

Costco.com has an "FSA Eligible" filter on its health categories. It sorts the catalog so you can shop only tagged items. Useful for finding things. Not proof of anything.

The payment side is less clear. As of September 2026, Costco.com's accepted-payment list does not name FSA or HSA cards. It names Visa, Mastercard, PIN debit, Costco Shop Cards, Visa Click to Pay, and Affirm. An HSA card is a Visa or Mastercard debit, so it may go through. Plan on the reimburse-yourself route and treat the card working as a bonus.

Costco Same-Day handles it differently. Its help pages describe a toggle to apply the FSA/HSA benefit at checkout. You can edit the amount it charges to the benefit card. Ineligible items and delivery fees go to the backup card. Save the order receipt the same way as any other.

What to Do With the Receipt

Thermal receipts fade. Photograph the Costco receipt the day you shop.

Tripl is an HSA receipt tracker that takes that photo and does the filing. Snap the receipt from your phone. Tripl reads the merchant, the date, and the total. Edit the total down to the eligible lines. Add a note like "allergy meds + contact solution." It files under a health category with the image attached.

The receipt is stored in the cloud. Connect Google Drive or Dropbox and it mirrors to your own account too. Two copies, two places. The fade problem and the lost-phone problem both go away.

Tripl is $30 per year for the first 100 sign-ups. After that, $50 a year.

Already lost a Costco receipt? Costco's help page says in-warehouse receipts show under Orders & Purchases on Costco.com for up to two years. New purchases can take up to 24 hours to appear. The lost HSA receipts post covers the other retailers.
