FSA Eligible Items for Women: What to Buy Before Dec 31 (2026)

By Sofía Castillo•Published October 27, 2026

FSA eligible items for women go well beyond tampons. If your plan year ends December 31, whatever is left in your health FSA usually disappears after that, unless your employer offers a grace period or a carryover. Here’s what you can actually buy, which items the IRS names outright, which ones depend on your plan, and how to spend what’s left without a denied claim.

This isn’t tax advice. It’s a plain-English guide built from IRS Publications 502 and 969, the CARES Act and the IRS’s 2026 limits, checked on October 27, 2026. Your plan document and your FSA administrator have the final word, so use this as your list of what to ask.

Quick answer

• By law, menstrual care products and over-the-counter medicines count. Since 2020, the CARES Act treats tampons, pads, liners, cups, sponges and similar products as medical care, and you don’t need a prescription for medicines like ibuprofen.
• The IRS names a few items outright: pregnancy test kits, breast pumps and supplies that assist lactation, birth control pills prescribed by a doctor, and condoms.
• Many favorites are administrator calls. Period underwear, ovulation tests, heating pads, sunscreen and nursing pads are generally accepted by FSA administrators, but the IRS doesn’t list them by name.
• Some things need a letter from your clinician. Under IRS rules, vitamins, including prenatals, qualify only when a practitioner recommends them for a diagnosed condition. Light therapy lamps and pelvic floor trainers usually need a letter of medical necessity too.
• The 2026 numbers: you could contribute up to $3,400, and if your plan has a carryover, up to $680 can roll into 2027. A plan can offer a grace period of up to 2½ months instead, never both, and plenty offer neither.

What counts as an FSA eligible item?

The IRS starts from one idea. Medical expenses are the costs of diagnosing, curing, mitigating, treating or preventing disease, or of affecting a part or function of the body. Publication 969 says a health FSA covers the expenses that would generally qualify for the medical deduction, and adds two things the deduction itself doesn’t allow: over-the-counter medicine, whether or not it’s prescribed, and menstrual care products.

What doesn’t count matters just as much. Publication 502 rules out items you’d use for everyday living unless they’re mainly for treating an illness, and its example is toothpaste. It also says nutritional supplements and vitamins don’t qualify unless a medical practitioner recommends them as treatment for a specific condition a physician diagnosed. Anything bought mainly for looks fails the same test.

There’s one 2026 update most lists haven’t caught yet. On September 23, 2026, the IRS added a question about wearables like rings, watches and patches to its FAQ. A device that tracks general wellness, fitness or sleep isn’t a medical expense just because it measures your health. It can qualify if you buy and use it mainly to diagnose, treat or prevent a specific disease. In the IRS’s words, “a generalized desire to monitor or improve health is not sufficient.”

That gives you three buckets, and the checklist below uses them: eligible by law or named by the IRS, generally accepted by administrators (plan practice, not an IRS list), and needs a letter of medical necessity (a short note from your clinician tying the item to a diagnosis).

FSA eligible items for women: the checklist

Before a big order, look up your own plan’s eligibility list. Most administrators publish one, and it’s the list your claim will be checked against.

Is period underwear FSA eligible? What the law actually says

The law doesn’t mention period underwear by name. Here’s the actual definition in CARES Act section 3702: a menstrual care product is “a tampon, pad, liner, cup, sponge, or similar product used by individuals with respect to menstruation or other genital-tract secretions.” It applies to FSAs, HSAs and HRAs for expenses after December 31, 2019.

Absorbent period underwear does the same job as a pad, which is why administrators generally accept it as a “similar product.” Because it’s a judgment call and not an IRS line item, a few things make the claim go smoothly:

• Buy from a store that marks FSA-eligible items, or keep an itemized receipt that clearly says “period underwear.”
• Stick to what you’ll actually use. A plan can question a claim that looks like a wardrobe refresh.
• If you’re unsure, check your administrator’s eligibility list before you buy a large set.

Pregnancy, fertility and postpartum

Pregnancy tests are the easy one: Publication 502 lists pregnancy test kits as a medical expense. If you’re wondering about timing, here’s how soon you can take a pregnancy test.

Ovulation tests and fertility monitors aren’t named by the IRS, but administrators generally accept them. Here’s how to read ovulation test strips, and our comparison of Inito vs Mira if you’re weighing a hormone monitor. Fertility treatment itself is named: Publication 502 includes procedures such as IVF, including temporary storage of eggs or sperm, to overcome an inability to have children. If you’re choosing a health plan right now, see whether insurance covers IVF and set your 2027 FSA election with that in mind.

Breast pumps are named too. Publication 502 says you can include “breast pumps and supplies that assist lactation,” but not excess bottles for food storage. Flanges, valves and tubing fit that wording. Nursing pads and storage bags are usually accepted, but that’s plan practice.

Prenatal vitamins are the gray area. The IRS says vitamins count only when a practitioner recommends them to treat a specific diagnosed condition. Some administrators reimburse prenatals during pregnancy with just a receipt, and others ask for a letter, so check before you buy a six-month supply.

Postpartum supplies like peri bottles and perineal cooling pads are generally accepted by administrators. Postpartum pads are on firmer ground: the CARES Act definition covers products used for menstruation “or other genital-tract secretions,” which fits bleeding after birth.

Keep in mind that a health FSA comes through a job. If you’re pregnant without coverage, our guide for anyone pregnant with no health insurance walks through Medicaid, CHIP and Marketplace options.

Cramps, bladder leaks and winter mood

Heating pads and heat wraps are generally accepted by administrators as pain relief, even though the IRS doesn’t list them. Our guide to the best heating pad for period cramps covers how long and how hot to use one.

Pelvic floor trainers usually need a letter of medical necessity, since plans see them as dual-use. A clinician who documents stress incontinence or postpartum weakness makes approval far more likely. Before you spend, read whether pelvic floor trainers work better than plain Kegels.

Light therapy lamps follow the same pattern. With a diagnosis of seasonal affective disorder and a letter, many plans reimburse them. Without one, expect a denial. Here’s how to choose a light therapy lamp for seasonal depression that actually reaches 10,000 lux at your distance.

Menopause and midlife: what usually needs a letter

Prescription treatment, including hormone therapy, is eligible as a prescribed medicine. Over-the-counter remedies with a drug ingredient count as OTC medicine. Plans differ on vaginal moisturizers and lubricants, so check your administrator’s list or ask about a letter if your clinician diagnosed vaginal dryness.

Cooling products are where claims often stall. Fans, cooling towels, pajamas and sheets have ordinary uses, so administrators usually want a letter tying them to diagnosed hot flashes, and many still say no. We’d plan on paying for cooling sheets for night sweats out of pocket.

Beauty and skin care: a short list

Most beauty products aren’t eligible, and that includes makeup, anti-aging serums and ordinary moisturizers. The exceptions are narrow, and both rely on administrator practice, not an IRS list:

• Sunscreen: administrators generally accept broad spectrum sunscreen with SPF 15 or higher. Publication 502 doesn’t mention sunscreen at all, and tinted products or makeup with SPF usually get turned down.
• Medicated acne products: treatments with a drug ingredient such as benzoyl peroxide, salicylic acid or adapalene are generally accepted as OTC medicine. A “glow” or “clarifying” product without one isn’t.

At-home IPL hair removal is cosmetic, so it isn’t eligible unless a clinician documents a medical condition it treats. If you’re curious anyway, here’s whether at-home IPL works.

The Dec 31 deadline: grace period, carryover or neither

Publication 969 calls FSAs “use-it-or-lose-it” plans. Your employer can soften that in one of two ways, but not both:

One detail matters if you’re switching to an HSA-eligible plan in 2027. Publication 969 says grace period coverage from a general-purpose health FSA only leaves you HSA-eligible if your FSA balance is zero at the end of the plan year. So if your plan has a grace period, spending the account down to zero by December 31 can protect your 2027 HSA contributions.

For next year’s election, it helps to know that your whole annual election is available from day one. Publication 969 says you must be able to get the full amount at any time during the coverage period, regardless of how much you’ve contributed so far.

How to use your FSA before Dec 31, step by step

1. Log in to your FSA portal and write down your exact balance and plan year end date.
2. Find out whether you have a grace period, a carryover or neither, and how long the run-out period is.
3. Book anything you’ve put off: a checkup copay, dental work, an eye exam or new glasses.
4. Refill prescriptions, then stock up on items you’ll truly use, like period care, pain relievers, tests and first-aid supplies.
5. For anything marked “needs a letter,” ask your clinician for a letter of medical necessity before you buy.
6. Pay with your FSA card where it’s accepted. If it’s declined, pay another way and file the receipt.
7. Keep itemized receipts showing the date, the store, the product name and the price.
8. File every claim before the run-out period ends, and don’t claim the same expense twice from an FSA and an HSA.

FSA-friendly picks we’ve already reviewed

These are products we’ve covered in depth elsewhere on the site. Check each listing for an FSA or HSA eligible label and confirm with your plan, because sellers and plans don’t always agree.

• Period care: Bambody period underwear and Thinx for All Everyday Comfort Brief for everyday wear, Always ZZZ Overnight for nights, and the Flex Disc if you prefer a disc.
• Cramps: the Sunbeam XL heating pad for the couch and ThermaCare Menstrual Heatwraps for a day out.
• Trying to conceive: Easy@Home ovulation strips (50-pack) for daily testing, the Clearblue Digital ovulation test if you want a yes or no answer, or a hormone monitor like the Inito Fertility Monitor or the Mira Fertility Max Kit.
• With a letter of medical necessity: Perifit for pelvic floor training, Poise Ultra Thin pads while you train, and the Verilux HappyLight Luxe or Carex Day-Light Classic Plus for diagnosed seasonal depression.

FSA vs HSA for these purchases

You generally can’t contribute to an HSA while you’re also covered by a general-purpose health FSA. A limited-purpose FSA, usually for dental and vision, is the exception Publication 969 allows.

Mistakes that get FSA claims denied

• Sending a receipt that only shows the store name and total, with no product names.
• Assuming an administrator-accepted item, like period underwear or sunscreen, is accepted by your plan without checking.
• Buying a dual-use item, like a light therapy lamp or a cooling fan, without the letter your plan requires.
• Treating a run-out period as extra shopping time.
• Ignoring a request for a receipt after a card swipe. Many plans suspend the card until you send it or repay the amount.

When to see a doctor (and when a visit helps your claim)

If you’re buying period products in bulk because your periods are very heavy, that’s worth a conversation with a clinician. The CDC lists these signs of heavy menstrual bleeding that should be checked:

• Bleeding that lasts longer than 7 days.
• Soaking a tampon or pad every hour or more often on the heaviest days.
• Passing clots bigger than a grape.
• Flooding that limits work, school, exercise or social plans, or being told you’re low in iron.

Also see a doctor for bladder leaks that don’t improve with pelvic floor exercises, low mood that lasts for weeks, or hot flashes that disrupt your sleep. A visit has a practical upside too. Your copay is an eligible FSA expense, and it’s your chance to ask for the letter of medical necessity that makes a trainer, a lamp or vitamins reimbursable.
