The March 15th FSA Deadline: How to Spend Your Balance Without Wasting Money
If you have money left in your 2025 Flexible Spending Account, you are likely facing the "Grace Period" deadline of March 15th.
If you don't spend that cash by midnight on the 15th, it is legally forfeited to your employer. This is the "use-it-or-lose-it" rule in its most aggressive form.
1. The "Grace Period" Rule Explained
The IRS allows employers to offer one of two "safety valves" for unused FSA funds. Most companies choose the Grace Period, which gives you until March 15th of the following year to spend the previous year's money.
Insider Tip: Claims for these purchases usually must be submitted by March 31st (known as the "Run-Out Period"). Do not wait until the last minute to upload your receipts, as systems often crash under high volume on deadline night.
The "Inventory" Loophole
You don't have to use the item by March 15th—you just have to own it. This is the perfect time to stockpile high-use items like SPF moisturizers, contact lenses, and first-aid tech that you know you will need during the summer months.
2. High-Value "Insider" Picks
Stop panic-buying $200 worth of bandaids and aspirin. Instead, use your remaining balance on high-utility health technology that provides long-term value.
Smart Health Wearables
Apple Watches and Oura Rings are eligible if used to monitor a specific medical condition. Use our LMN Tool to get your documentation ready before you buy.
Percussive Therapy (Theragun)
Facing chronic back pain or muscle recovery issues? High-end massage guns are fully reimbursable with a medical necessity letter from your chiropractor or GP.
High-End Baby Tech
If you have a 2025 balance and a new baby, the Nanit Pro Camera and Owlet Sock are high-value ways to spend down $300+ in a single transaction.
3. The Skincare Stockpile Strategy
Under the CARES Act, you no longer need a prescription for OTC drugs. Any skincare product that treats Acne or provides SPF 15+ is eligible. This includes luxury brands like La Roche-Posay, EltaMD, and Supergoop.
