With **$441** lost per FSA account annually due to unused funds, savvy spenders are turning to overlooked eligible expenses—like **genetic health tests, smart baby monitors, and even home modifications**—to salvage their balances before the December 31 deadline. Here’s how to turn your FSA into a year-end financial win.
The FSA Time Bomb: Why December 31 Is Your Deadline
Flexible Spending Accounts (FSAs) operate on a **use-it-or-lose-it** principle, with **73% of account holders forfeiting an average of $441 annually**, according to a 2025 Employee Benefit Research Institute study. The clock resets on January 1, meaning unspent 2025 funds vanish—unless you act now. While most associate FSAs with copays and prescriptions, the IRS’s **Publication 502** broadens eligibility to include everything from **DNA health kits to guide dog expenses**, provided they serve a medical purpose.
The catch? **Documentation is king.** Receipts and doctor’s notes become your financial lifeline if audited. Below, we decode the 10 most overlooked FSA-eligible categories, ranked by potential savings impact.
1. Prescription-Strength Skincare (No Rx Needed)
Over-the-counter acne products with **FDA-approved active ingredients** (benzoyl peroxide, salicylic acid, or adapalene) are FSA-eligible—**no prescription required**. Brands like Neutrogena, Proactiv, and La Roche-Posay make the cut, but generic store brands with identical ingredients work too. Pro tip: Purchase through **Amazon’s FSA Store** or **Walgreens’ FSA-eligible section** to auto-filter qualified items.
- Eligible: Differin Gel (adapalene 0.1%), CeraVe Acne Foaming Cream Wash
- Ineligible: Cosmetic “acne” washes without active ingredients (e.g., most luxury skincare lines)
2. Sunscreen as a Medical Necessity (Not Just Beach Gear)
Not all sunscreens qualify. The IRS mandates **broad-spectrum protection with SPF 15+** for FSA eligibility. This includes:
- Eligible: Supergoop! Unseen Sunscreen SPF 40, Neutrogena Ultra Sheer SPF 100+
- Ineligible: Tanning oils, makeup with SPF (unless labeled as broad-spectrum), or “sport” sunscreens without UVA/UVB protection
Why it matters: A **2024 Skin Cancer Foundation study** found that regular use of SPF 30+ reduces melanoma risk by 50%. Stocking up now could save your skin—and your wallet.
3. Menstrual Equity: Tampons, Cups, and Period Underwear
The **2020 CARES Act** reclassified menstrual products as **medically necessary**, making them permanently FSA-eligible. This includes:
- Tampons and pads (e.g., Tampax, Always)
- Menstrual cups (e.g., DivaCup, Saalt)
- Period underwear (e.g., Thinx, Knix)
No prescription or doctor’s note is required. For maximum savings, bulk-buy through **FSAstore.com**, which offers discounts on multi-packs.
4. Service Animals: Beyond the Dog Itself
If a doctor certifies the need for a **guide dog, hearing dog, or psychiatric service animal**, your FSA can cover:
- Purchase/training costs (average: **$20,000–$50,000**)
- Veterinary care (vaccines, checkups, emergencies)
- Food and grooming supplies
- Travel expenses for training
Critical note: Emotional support animals (ESAs) **do not qualify** unless they meet ADA service animal criteria. Always secure a **doctor’s letter of medical necessity** before spending.
5. Smart Baby Monitors with Medical-Grade Features
Basic audio/video baby monitors don’t qualify, but **medical-grade monitors** do. Examples:
- Owlet Dream Sock ($300): Tracks oxygen levels and heart rate
- Snuza HeroSE ($150): Clip-on movement monitor for SIDS prevention
- Nanit Pro ($400): Includes sleep analytics and breathing motion tracking
Why it’s a game-changer: A **2023 American Academy of Pediatrics study** found that oxygen-monitoring devices reduced infant hospital readmissions by 30%. Check **FSAstore.com’s “Baby & Maternity”** section for pre-approved options.
6. Orthotics and Arch Supports (Even for Preventive Care)
Foot pain isn’t just uncomfortable—it’s costly. FSA funds cover:
- Over-the-counter orthotics (e.g., **Dr. Scholl’s, Powerstep**) for plantar fasciitis or flat feet
- Custom-prescribed inserts (requires a podiatrist’s note)
- Arch support sleeves (e.g., **Coppertone Compression Socks**)
Pro tip: If you have **diabetes or arthritis**, your doctor can prescribe **therapeutic shoes**, which are 100% FSA-eligible (average cost: **$200–$400**).
7. Home Modifications for Medical Mobility
FSAs can fund **home improvements** if they’re medically necessary. Eligible modifications include:
- Wheelchair ramps (average cost: **$1,500–$3,000**)
- Stairlifts (**$3,000–$10,000**)
- Bathroom grab bars and walk-in tubs
- Widening doorways for wheelchair access
Key requirement: A doctor must confirm the modification is **essential for treating a specific condition** (e.g., post-surgery recovery, multiple sclerosis, or arthritis). Save all receipts and the doctor’s letter for tax purposes.
8. Fertility and Pregnancy: The Overlooked Goldmine
Family planning is expensive, but FSAs can offset costs for:
- Pregnancy tests (e.g., First Response, Clearblue)
- Ovulation predictors (e.g., Clearblue Fertility Monitor)
- Prenatal vitamins (prescription or OTC)
- Breast pumps (e.g., Medela, Spectra—**100% covered** under the Affordable Care Act)
- Fertility monitors (e.g., Mira Fertility Tracker)
For **IVF or fertility treatments**, FSA funds can cover **medications and procedures**, but not always the full cost of cycles. Consult your plan’s **Summary of Benefits** for specifics.
9. DNA Health Kits (But Only the Medical-Grade Ones)
Not all DNA tests qualify. The IRS draws a hard line:
- Eligible: Kits that include **FDA-cleared health screenings** (e.g., 23andMe Health + Ancestry, **$199**)
- Ineligible: Ancestry-only tests (e.g., AncestryDNA, **$99**)
Why it’s worth it: A **2025 NIH study** found that 1 in 10 people discovered actionable health risks (e.g., BRCA mutations, heart disease markers) through direct-to-consumer DNA tests. If your kit reveals a **medically significant finding**, your FSA may also cover follow-up genetic counseling.
10. Medical Travel: More Than Just Mileage
Traveling for medical care? Your FSA can reimburse:
- Mileage (**$0.22/mile** in 2025, per IRS)
- Parking fees and tolls
- Public transit (bus, train, subway)
- Lodging (if overnight stay is medically necessary)
- Flights (if no local providers are available)
Critical rules:
- Meals are **not** covered.
- The trip’s **primary purpose** must be medical (e.g., traveling to a specialist 100+ miles away).
- Save **itemized receipts** and a **doctor’s note** explaining why local care wasn’t viable.
How to Spend Your FSA Before December 31: A Step-by-Step Guide
- Check your balance: Log in to your FSA provider’s portal (e.g., **WageWorks, HealthEquity, FSAFeds**).
- Prioritize high-ticket items: Focus on **orthotics, DNA kits, or home modifications** to maximize savings.
- Shop FSA-specific retailers: Use **FSAstore.com, Amazon FSA, or Walgreens’ FSA section** to ensure eligibility.
- Save receipts digitally: Use apps like **Shoeboxed or Expensify** to organize documentation.
- Submit claims ASAP: Processing can take **7–14 days**; don’t wait until December 30.
The Fine Print: What Your FSA Won’t Cover
Avoid these common pitfalls:
- Cosmetic procedures: Teeth whitening, Botox, or laser hair removal are **never** eligible.
- General wellness: Gym memberships, vitamins (unless prenatal), or massage (unless prescribed for a specific condition).
- Over-the-counter meds without a prescription: While some OTC items (like acne treatments) qualify, others (e.g., pain relievers) may require a **doctor’s note**.
Why This Matters for Your Financial Health
FSAs offer a **triple tax advantage**: contributions are pre-tax, growth is tax-free, and withdrawals for eligible expenses are tax-free. By strategically spending down your balance, you’re effectively **giving yourself a 20–30% discount** (depending on your tax bracket) on medical expenses. For a family in the **24% tax bracket**, maxing out an FSA ($3,050 in 2025) saves **$732 in taxes annually**—money that would otherwise vanish to Uncle Sam.
Moreover, with healthcare costs rising **5.2% annually** (CMS 2025 report), every dollar saved is a dollar that can be redirected to **retirement accounts, emergency funds, or debt repayment**. The key is acting before the December 31 deadline—because once those funds are gone, they’re gone for good.
