FSA Eligible Items: Complete Spending Guide

Every year, millions of Americans leave money on the table simply because they don’t know what their flexible spending account covers. Understanding FSA eligible items is the single most effective way to get full value from your employer-sponsored benefit. For 2026, the IRS employee contribution limit for a health FSA is roughly $3,400 (verify the current figure with your plan, as the IRS adjusts it annually), and knowing exactly where that money can go makes a real difference in your household budget.

This guide breaks down the full range of products and services that qualify, from obvious medical expenses to items you might never have considered – along with the categories that clearly do not qualify, so you don’t get a claim denied. Whether you’re new to FSAs or a seasoned account holder, you’ll find practical ways to put every dollar to work before the plan year ends.

What Counts as an FSA Eligible Item?

The IRS defines qualified medical expenses in Publication 502 and Section 213(d) of the tax code. In broad terms, any product or service used to diagnose, treat, cure, mitigate, or prevent a disease or medical condition qualifies. Cosmetic procedures and general wellness products that don’t address a specific medical need typically do not. (One nuance: Publication 502 is written for the medical-expense tax deduction, which still excludes most non-prescription drugs; FSA rules are broader because the 2020 CARES Act specifically made OTC medicines reimbursable from an FSA – more on that below.)

Your FSA administrator may maintain a list of approved items, but the underlying authority comes from IRS guidelines. If an expense meets the qualified-medical-expense definition, you can generally submit it for reimbursement even if it isn’t printed in your plan’s quick-reference guide. When something is genuinely ambiguous, your plan may ask for a letter of medical necessity from your provider – but, as noted later, that letter cannot turn an ordinary personal expense into a medical one.

Common FSA Eligible Items You Already Know

Most people associate their FSA with doctor-visit copays, prescription medications, and dental work. These are the bread-and-butter expenses that make up the majority of FSA spending nationwide. Copayments, coinsurance, and deductibles for medical, dental, and vision care all qualify.

Prescription drugs are straightforward. Any medication prescribed by a licensed provider and dispensed by a pharmacy is eligible, including insulin. This covers maintenance medications for chronic conditions like blood pressure, cholesterol, and diabetes management.

Dental expenses such as fillings, crowns, root canals, orthodontia, and dental X-rays all qualify. Vision expenses including eye exams, prescription glasses, prescription sunglasses, contact lenses, and contact-lens solution round out the most commonly claimed FSA eligible items. Hearing aids and their batteries are eligible too.

Over-the-Counter Products That Qualify

Since the CARES Act of 2020, over-the-counter medications no longer require a prescription to be FSA eligible – a permanent expansion that many account holders still don’t fully use. Pain relievers like ibuprofen and acetaminophen, allergy medications such as cetirizine and loratadine, and cold and flu remedies all qualify when purchased with FSA funds.

Menstrual care products – including tampons, pads, liners, and menstrual cups – became permanently eligible under the same legislation. Sunscreen with an SPF of 15 or higher also qualifies, making it one of the easiest preventive-care purchases you can make with your account.

First-aid supplies deserve a mention as well. Bandages, antiseptic wipes, thermometers, blood-pressure monitors, and heating pads are all reimbursable. Stocking a well-equipped first-aid kit with FSA dollars is a practical move that many people overlook.

FSA Eligible Items That Surprise People

Acupuncture treatments for a medical condition are eligible. So are chiropractic services, physical therapy, and speech therapy. If your provider prescribes a CPAP machine or supplies for sleep apnea, those costs come straight from your FSA.

Travel costs related to medical care can also qualify. Mileage driven to and from medical appointments, parking fees at the hospital, and even bus or train fare to a provider’s office are reimbursable under IRS rules. The IRS sets a standard medical-mileage rate each year (it was 21 cents per mile in 2025; verify the current rate before you file), so it’s worth tracking if you have frequent appointments.

Fertility treatments, including in-vitro fertilization, are FSA eligible. Breast pumps and lactation supplies qualify for new parents. Even guide dogs and service animals trained to assist with a specific disability count as eligible medical expenses according to IRS Publication 502.

Items That Do NOT Qualify

General health and wellness products are the most common point of confusion. Gym memberships, fitness trackers, vitamins taken for general health, and nutritional supplements without a medical diagnosis typically fall outside the eligible list. Cosmetic procedures like teeth whitening, aesthetic hair removal, and elective cosmetic surgery are also excluded.

Health insurance premiums generally cannot be paid with FSA funds. This is a frequent question, and the answer is clear under IRS guidelines. Similarly, expenses reimbursed by another source, including insurance payouts, cannot be double-claimed through your FSA.

Over-the-counter items marketed as wellness or beauty products rather than medical treatments generally won’t qualify. When in doubt, check whether the product treats a specific medical condition or simply promotes general well-being – that distinction is the dividing line the IRS draws.

Beware “Letter of Medical Necessity” Schemes

In 2024 the IRS issued a specific warning (news release IR-2024-65) after some companies claimed that a “letter of medical necessity” could make everyday food, wellness, or exercise spending reimbursable through an FSA, HSA, or similar account. It can’t. A letter of medical necessity can support an expense that is genuinely medical but ambiguous; it cannot convert general-health purchases – groceries, standard gym memberships, wellness subscriptions – into qualified medical expenses. Improperly reimbursed amounts can become taxable and, in the case of HSAs, subject to penalties. If a vendor promises that a letter unlocks reimbursement for ordinary personal spending, treat it as a red flag and confirm with your plan administrator or a tax professional.

How to Maximize Your FSA Spending

Start by auditing your household’s recurring medical expenses. Tally up prescription costs, regular copays, dental cleanings, vision exams, and any ongoing therapy or treatment. This gives you a baseline for setting your annual contribution during open enrollment – and helps you avoid over-funding an account you can’t fully spend.

Next, consider stocking up on eligible OTC products before your plan year ends. If you have remaining funds, purchasing a year’s supply of allergy medication, contact-lens solution, or first-aid supplies is a smart way to avoid forfeiting money under the use-it-or-lose-it rule.

Keep receipts and documentation for every purchase. Many FSA administrators offer mobile apps that let you snap photos of receipts and submit claims on the spot. Building that habit early in the plan year saves a scramble in December. For a broader look at how FSAs fit into your overall spending strategy, see our healthcare costs guide.

Use-It-or-Lose-It, Grace Periods, and Carryover

The defining feature of a health FSA is the use-it-or-lose-it rule: money you don’t spend by the deadline is generally forfeited. The IRS allows employers to soften this in one of two ways (not both): a grace period of up to 2.5 extra months to incur expenses, or a limited carryover into the next plan year. For 2026 the maximum carryover is roughly $680 (verify with your plan, since this limit is indexed and your employer may set it lower or not offer it at all). Check your specific plan documents to see which option, if any, applies to you – and mark the deadline on your calendar.

FSA Eligible Items vs. HSA Eligible Items

The list of qualifying expenses is nearly identical for both FSAs and health savings accounts. Both follow the same IRS qualified-medical-expense rules, so the same medical products and services apply. The key differences are structural rather than expense-related. HSAs require enrollment in a high-deductible health plan, let unused funds carry over indefinitely, and offer investment options. For a detailed comparison, see our guide on HSA vs FSA differences.

One practical distinction matters for shopping. Many retailers flag items as “FSA/HSA eligible” with a single label because the qualifying criteria are the same. If a product is marked eligible at checkout, it generally applies to both account types – though the store’s label is a convenience, not an IRS ruling, so keep your receipt.

Frequently Asked Questions

Can I use my FSA card at any store?

You can use your FSA debit card at pharmacies, medical-supply stores, and many major retailers that carry eligible products. Some stores use an inventory system (IIAS) that automatically verifies item eligibility at the point of sale. For purchases at retailers without this verification, you may need to submit a manual reimbursement claim with your receipt.

What happens to unused FSA funds at the end of the year?

Most FSAs operate under a use-it-or-lose-it rule. However, your employer may offer either a grace period of up to 2.5 extra months or a carryover (about $680 for 2026 – verify your plan’s amount) into the next plan year. Check your specific plan documents to see which option, if any, your employer provides.

Do I need a prescription for over-the-counter FSA purchases?

No. Since the CARES Act took effect in 2020, over-the-counter medications and menstrual-care products are eligible without a prescription. This applies to pain relievers, allergy medications, cold remedies, and many other OTC products.

Are orthodontics and braces FSA eligible?

Yes. Orthodontic treatment, including braces and retainers, qualifies as an FSA eligible expense. You can pay for the treatment in installments and submit each payment for reimbursement as it occurs during the plan year, subject to your plan’s rules.

Can I buy glasses or contacts with my FSA?

Prescription eyeglasses, prescription sunglasses, contact lenses, and contact-lens solution are all FSA eligible items. Non-prescription (plano) sunglasses and blue-light-blocking glasses without a prescription generally do not qualify.

Make Every FSA Dollar Count

Your flexible spending account is one of the most straightforward tax advantages available to working Americans. The key is knowing the full range of FSA eligible items so you can plan contributions accurately and spend down your balance before the deadline. Review IRS Publication 502 for the authoritative list of medical expenses, check with your plan administrator for any plan-specific restrictions and your current contribution and carryover limits, and consult a tax professional if you have questions about a particular expense. With thoughtful planning, a workplace benefit turns into meaningful savings on the medical expenses your household already incurs.
