Things I didn't realize were HSA/FSA-eligible until I actually tracked my receipts
Went back through a year of CVS / Amazon / Walmart receipts and realized I'd been leaving real money on the table by not knowing what actually counts.
Sharing the surprising ones in case anyone else is sitting on a drawer of receipts:
☀️ Sunscreen (SPF 15+) — fully eligible, no doctor's note needed.
💄 Lip balm with SPF — same. Often missed because it rings up as "cosmetics."
🦷 Medicated toothpaste (Sensodyne, prescription fluoride) - eligible. Regular toothpaste is not.
🤱 Breast pumps + accessories (Elvie, Willow, replacement parts) — eligible.
🧴 Acne treatments (benzoyl peroxide, adapalene) — yes, even OTC, since the 2020 CARES Act.
🩸 Period products (tampons, pads, cups, period underwear) — also CARES Act.
🏋️ Gym membership / Peloton / treadmill — eligible with a Letter of Medical Necessity. Obesity, hypertension, and diabetes risk are common qualifying conditions.
💆 Massage therapy — same: needs an LMN tied to a specific condition (back pain, migraines).
🩹 First aid kits, thermometers, blood pressure cuffs — all eligible, almost never claimed.
⏳ The HSA play that took me too long to internalize:
You don't have to reimburse yourself now. Pay out of pocket, let the HSA compound tax-free for years, then reimburse yourself in 10 / 20 / 30 years with the original receipts as proof. The IRS has no statute of limitations on reimbursement as long as the expense was incurred after the HSA was opened.
🛠️ Which is why I got annoyed enough to build a small tool to track all this. Runs entirely in your browser. No account. No server. Nothing leaves your device.
Snap a receipt, it classifies each line, you keep the receipts forever. Built it because I didn't trust uploading years of medical receipts to a SaaS.
