FSA-eligible items in 2026: the complete list (plus the surprising ones most people miss).

A Flexible Spending Account (FSA) lets you spend pre-tax dollars on a much wider range of healthcare items than most people realize. Since the CARES Act of 2020, you no longer need a prescription for most over-the-counter (OTC) medications. The 2026 annual contribution limit is $3,400 (up from $3,300 in 2025). Use it on the obvious (copays, prescriptions, glasses) and on the surprising (sunscreen, period products, breast pumps, foot orthotics). Here's the complete list by category, plus the year-end-spend-down strategy if you'll lose unused funds.

How FSA eligibility actually works

The IRS defines a "qualified medical expense" in IRC §213(d) as an amount paid for "the diagnosis, cure, mitigation, treatment, or prevention of disease, or for the purpose of affecting any structure or function of the body." The IRS doesn't publish a master product list — instead, the FSA administrator (e.g., HealthEquity, WageWorks, Optum) decides what they'll reimburse based on that definition. Most administrators publish their own eligibility list; the major retailers (Amazon, FSA Store, Target) maintain searchable databases. When in doubt, save the receipt and submit; if denied, you'll get the reason in writing.

OTC items now FSA-eligible (CARES Act 2020+, no Rx needed)

The biggest under-used category. Before 2020 you needed a prescription from your doctor to FSA-reimburse OTC drugs. The CARES Act permanently removed that requirement. This category is huge:

OTC medications

• Pain relievers (Tylenol, Advil, Aleve, aspirin).
• Cold and flu medicine (DayQuil, NyQuil, Mucinex, cough drops, decongestants).
• Allergy medicine (Zyrtec, Claritin, Benadryl, Flonase).
• Antacids and heartburn (Tums, Prilosec OTC, Pepcid AC).
• Anti-diarrheals and laxatives.
• Sleep aids (melatonin, ZzzQuil, Unisom).
• Nicotine patches and gum (smoking cessation).
• Topical creams (hydrocortisone, antibiotic ointments, anti-fungal).

Menstrual products (CARES Act addition)

• Tampons, pads, liners, period underwear.
• Menstrual cups.
• Heating pads for cramps.

Sun and skin

• Sunscreen (SPF 15+).
• Sunburn relief (aloe-based).
• Lip balm with SPF.
• Acne treatments (OTC).

First aid + medical supplies

• Bandages, gauze, antiseptic wipes, peroxide.
• Thermometers (oral, ear, forehead, smart).
• Blood pressure monitors.
• Pulse oximeters.
• Glucose monitors and test strips (diabetes).
• Heating pads and ice packs.
• Crutches, canes, walkers.
• Knee braces, ankle braces, back supports.

PPE and at-home testing

IRS Announcement 2021-7 made personal protective equipment purchased to prevent the spread of COVID-19 reimbursable, and administrators have kept these codes active:

• Face masks (disposable and reusable).
• Hand sanitizer and sanitizing wipes.
• At-home COVID-19 test kits.
• At-home flu, strep, and UTI test kits (most administrators code these as diagnostic).

Family planning and pregnancy

• Condoms.
• Prenatal vitamins (one of the few vitamin categories eligible without documentation).
• Baby health basics: nasal aspirators, infant thermometers, electrolyte solution.
• Sunscreen and diaper rash cream for kids (the SPF and active-ingredient rules apply regardless of age).

Surprising eligible items most people miss

• Breast pumps + supplies. Manual or electric. Storage bags. Replacement parts.
• Lactation consultant fees. Documented IBCLC visits.
• Pregnancy tests + fertility kits. Including ovulation predictor kits.
• Childbirth classes. If the class teaches you what's medically happening during labor + delivery.
• Sunglasses prescription (with diopter; non-Rx sunglasses generally aren't).
• Reading glasses over-the-counter (no Rx needed).
• Smoking-cessation programs + nicotine replacement therapy.
• Weight-loss programs for a doctor-diagnosed obesity condition (with a letter of medical necessity).
• Acupuncture sessions.
• Chiropractic care.
• Mental health therapy (psychologist, psychiatrist, licensed counselor).
• CGM sensors (Dexcom, Libre) for diabetics.
• Foot orthotics + arch supports + diabetic shoes.
• Bedding for allergies (mattress encasings if doctor-prescribed for dust mite allergy).
• Air purifiers (with Letter of Medical Necessity for specific allergy/asthma diagnosis).
• Home defibrillators (AED).
• Genetic testing (23andMe Health, others — only the health-component portion of the cost).
• Service animal expenses (food, training, vet care).
• Transportation to medical appointments (mileage at $0.21/mile for 2026, parking, tolls).

Items that need a Letter of Medical Necessity

A Letter of Medical Necessity (LMN) is a short, dated note from a licensed provider stating three things: your diagnosis, the specific product or service being recommended, and how that product treats the diagnosed condition. It converts a dual-purpose item (something usable for general health) into a qualified medical expense for you specifically. Most administrators want the letter on file before they'll approve the claim, and many require a fresh one each plan year.

Items that commonly clear with an LMN:

• Weight-loss programs (WW, Noom, medically supervised plans) for diagnosed obesity, hypertension, or type 2 diabetes. Program fees qualify; the food itself generally doesn't.
• Vitamins and supplements prescribed for a documented deficiency: vitamin D for a confirmed low level, iron for anemia, B12 after bariatric surgery.
• Air purifiers and humidifiers for diagnosed asthma or severe allergies.
• Massage therapy for a specific musculoskeletal diagnosis, not general relaxation.
• Special infant formula (the cost difference above standard formula) for diagnosed allergies or metabolic disorders.
• Compression garments beyond standard OTC stockings, for lymphedema or post-surgical recovery.

One caution worth knowing: in March 2024 the IRS publicly warned about companies selling boilerplate LMNs that claim to make groceries, gym memberships, and general wellness purchases reimbursable. A doctor's note cannot turn a personal expense into a medical one. If a vendor promises that everything in your cart becomes FSA-eligible with their letter, the claim can be denied retroactively and the reimbursement added back to your taxable income. Stick to letters from your own treating provider tied to a real diagnosis.

NOT eligible (commonly assumed but won't reimburse)

• Gym memberships — even with a Letter of Medical Necessity, IRS has explicitly denied this.
• Cosmetic procedures — teeth whitening, Botox (cosmetic), face lifts, breast augmentation (cosmetic). Reconstructive surgery is eligible.
• Vitamins and supplements for general health — eligible only if specifically prescribed for a diagnosed condition.
• Toiletries — toothbrushes (non-electric), toothpaste, mouthwash, soap, shampoo, deodorant, lotion (general).
• Funeral expenses.
• Health club / fitness equipment for general fitness.
• Maternity clothes.
• Diaper service.
• Premiums for individual health insurance (HSA can; FSA generally cannot — with limited exceptions).
• Electric toothbrushes — classified as general dental hygiene, even with gum-disease history.
• CBD products — most administrators deny these because federal eligibility is unsettled.
• Childcare and daycare — that's a Dependent Care FSA, a separate account with its own election and rules. Health FSA funds can never cross over.
• Marriage counseling — not eligible, though therapy for a diagnosed mental health condition is.

Where to shop FSA-eligible

• FSA Store (fsastore.com) — 4,000+ products pre-verified eligible. Auto-substantiation = no receipt submission needed.
• HSA Store (hsastore.com) — sister site, also FSA-eligible.
• Amazon FSA Store — large eligible-product catalog, Prime-eligible.
• Target FSA + HSA Shop — in-store and online.
• Walgreens / CVS / Rite-Aid — most pharmacies code FSA-eligible items in their POS systems.
• Optical retailers (Warby Parker, Zenni) take FSA cards directly.

Year-end spend-down strategy

Most FSAs are use-it-or-lose-it, with two exceptions employers may offer:

• $680 carryover (2026 limit): up to $680 of unused funds can roll to next plan year.
• 2.5-month grace period: an extra ~10 weeks after plan-year-end to spend remaining funds.

Your employer picks ONE of these options, not both. Or neither. Check your plan documents in October so you know your end-of-year window. If you'll lose unused funds, plan a December spend-down:

1. Stock up on OTC essentials: pain relievers, allergy meds, cold/flu medicine, first aid supplies, sunscreen, period products, contact solution, lip balm with SPF. Long shelf life, you'll use them anyway.
2. Schedule eye exams + buy glasses (frames, lenses, prescription sunglasses).
3. Stockpile contact lenses (1-year supply).
4. Pre-pay dental work (cleanings, planned procedures).
5. Buy planned medical equipment (blood pressure monitor, thermometer, heating pad).
6. Refill prescriptions 90-day supply before year-end.

Grace period vs run-out period: two different deadlines

These two deadlines trip people up every January. The grace period (if your plan has one) extends the window for incurring new expenses: you can keep swiping the card on fresh purchases for roughly ten weeks into the new year. The run-out period is different and nearly universal: it's the deadline for submitting claims on expenses you already incurred during the plan year, typically 90 days after the year ends. A December eye exam paid out-of-pocket can still be reimbursed in February under the run-out rule even if your plan has no grace period at all. Check both dates in your plan documents; they're listed separately.

The FSA vs HSA decision

If your employer offers both, you usually have to choose one (unless you have a Limited Purpose FSA — dental + vision only — which can pair with an HSA).

• FSA wins when: you don't have an HDHP, you spend $1K-$3K/year on healthcare predictably, you want to use it on broad OTC categories.
• HSA wins when: you have an HDHP, you can invest the contribution for long-term growth, you're early-to-mid career and want the triple tax advantage.

Documentation: when you'll need a receipt

FSA administrators auto-substantiate (no receipt needed) when:

• You use your FSA debit card at a retailer with an IIAS-certified Inventory Information Approval System (most major pharmacies + grocery + FSA Store).
• The purchase matches a recognized FSA-eligible product code in their database.

You'll need to submit a receipt when:

• The transaction doesn't auto-substantiate (smaller retailer, online store without IIAS).
• You paid out-of-pocket and want reimbursement.
• Items with documentation requirements (Letter of Medical Necessity for things like air purifiers, weight-loss programs).

Keep digital copies of all FSA receipts for at least 3 years — IRS audit window. Most administrators have mobile apps with receipt-capture features that timestamp the upload.

Questions that come up every December

Whose expenses can I pay with my FSA?

Yours, your spouse's, and your tax dependents', even if they aren't enrolled in your health insurance plan. Your spouse's dental crown qualifies even if she's on her own employer's coverage. Adult children qualify through the end of the year they turn 26 under most plans.

What happens to my FSA if I leave my job?

Unspent funds generally forfeit on your termination date. You can still submit claims during the run-out window, but only for expenses incurred while you were employed. If you're planning an exit, spend the balance down first. There's a flip side worth knowing: the uniform coverage rule requires your full annual election to be available on day one of the plan year. Elect the maximum in January, spend it on LASIK in February, leave in March: you keep the benefit, and your employer cannot bill you for the difference. The rule cuts both ways, which is exactly why employers like forfeitures.

Can I change my election mid-year?

Only after a qualifying life event: marriage, divorce, birth or adoption, a dependent losing eligibility, or a change in your or your spouse's employment status. Realizing in July that you elected too much is not a qualifying event. Set October-November calendar reminders to estimate next year's spending before open enrollment closes.

Which date counts: service date or payment date?

The date of service controls, not the billing date. A procedure performed December 28 counts against this plan year even if the bill arrives in February. Conversely, prepaying in December for a January procedure usually doesn't work; orthodontics is the main exception, since administrators allow payment-plan reimbursement as treatment progresses.

Can I use my FSA and HSA on the same expense?

No. Each dollar of expense can be reimbursed once, from one account. You also can't claim an FSA-reimbursed expense as an itemized medical deduction. Administrators flag duplicates, and the IRS treats double-dipped reimbursements as taxable income.

Spending the account down to zero

FSAs are dramatically more flexible than most account holders realize. The annual contribution is pre-tax (saves federal income tax + FICA + state tax in most states); spending it on the obvious medical items is just step one. Use the surprise-eligible categories (sunscreen, period products, breast pumps, foot orthotics, prescription sunglasses, OTC stockpile) to make sure you spend every dollar before year-end. Know your plan's specific deadlines (carryover, grace period, run-out) by October, not December 28. Combined with FSA Store auto-substantiation, there's no excuse to forfeit unused funds.
