Why Your FSA Deadline Matters More Than You Think

Flexible Spending Accounts (FSAs) offer a powerful tax advantage β€” but most come with a strict "use it or lose it" rule. As December 31st approaches, millions of Americans risk forfeiting hundreds of dollars in pre-tax contributions simply because they didn't plan ahead. For people managing diabetes, this deadline represents a genuine opportunity to stock up on essential, qualifying supplies without paying out of pocket.

Understanding how to spend your remaining FSA balance strategically can save you significant money while ensuring you're well-supplied heading into the new year.

What Diabetes Supplies Are FSA-Eligible?

The IRS allows FSA funds to be used on a wide range of diabetes-related products and services. Knowing what qualifies helps you prioritize your spending effectively.

  • Blood glucose meters and continuous glucose monitors (CGMs)
  • Test strips and lancets
  • Insulin and insulin syringes
  • Insulin pump supplies and accessories
  • Diabetic wound care and foot care products
  • Prescription medications
  • Glucose tablets and gels (used for hypoglycemia treatment)
  • Diabetic socks and compression stockings (with a letter of medical necessity in some cases)

Retailers like mdsdiabetes.com carry a broad selection of FSA-eligible diabetes supplies, making it easy to browse and purchase qualified products before your funds expire.

5 Smart Strategies to Spend FSA Funds Before December 31st

1. Audit Your Current Supplies

Take inventory of what you have and what you'll realistically need in the next three to six months. Running low on test strips, CGM sensors, or lancets? Now is the perfect time to restock at no additional after-tax cost.

2. Schedule Overdue Appointments

Copays for endocrinologist visits, ophthalmologist exams, podiatrist appointments, and diabetes education programs are all FSA-eligible. Booking these before December 31st puts your pre-tax dollars to work.

3. Invest in Monitoring Technology

If you've been considering upgrading your glucose monitoring system, year-end is an ideal time. CGMs and newer blood glucose meters often qualify and can meaningfully improve your diabetes management long-term.

4. Stock Up on Consumables

Test strips, infusion sets, reservoirs, and lancets have long shelf lives. Purchasing a three-month supply using FSA funds before the deadline is a practical, high-value use of remaining dollars.

5. Don't Forget Over-the-Counter Items

Since the CARES Act of 2020, many OTC diabetes-related items no longer require a prescription to be FSA-eligible. This includes glucose tablets, certain wound care products, and more.

Watch Out for These Common FSA Mistakes

  • Waiting until the last week of December when products may be backordered
  • Assuming all health-related products qualify β€” always verify eligibility
  • Forgetting that some plans offer a grace period or $610 rollover β€” check your plan documents
  • Neglecting to save receipts for FSA reimbursement documentation

Plan Ahead for Next Year Too

Once you've navigated this year's deadline, use the experience to better estimate your FSA contribution for the coming year. Review what you actually spent on diabetes supplies, medications, and appointments in 2024 to set a realistic, tax-advantaged contribution amount for 2025.

Make Every FSA Dollar Count

Your FSA contributions are already tax-free β€” spending them wisely on diabetes essentials means maximizing a benefit you've already earned. Explore the FSA-eligible product catalog at mdsdiabetes.com to find supplies that fit your management needs and help you close out the year with your health and your wallet both in good shape.
