Millions of American workers are sitting on hundreds—sometimes thousands—of dollars that will vanish if they don't act soon.
It's not a scam or a forgotten bank account.
It's the money tucked inside a flexible spending account, and the clock is running out.
FSAs let you set aside pre-tax dollars for medical or dependent care costs, lowering your taxable income in the process.
The catch: for most plans, the funds don't roll over.
If you don't spend the balance by your plan's deadline, you forfeit it, often on December 31.
Employers get to keep whatever's left, and a lot of it goes unclaimed every year.
Many employers offer a grace period of up to 2.5 months into the next year, or let you carry over a limited amount—$640 for 2025, adjusted annually by the IRS.
That means the only way to know your real cutoff is to check your plan documents or call your benefits administrator directly.
The good news is that spending the money is easier than people assume.
FSA dollars cover far more than doctor visits.
Eligible expenses often include prescription glasses and contacts, dental cleanings and fillings, hearing aids, bandages, thermometers, and even sunscreen with an SPF of 15 or higher.
Over-the-counter medicines have been eligible without a prescription since 2020.
If you're short on time, online FSA stores let you stock up on eligible items in one sitting.
Many retailers flag which products qualify, so you can verify before checkout.
Just remember to keep your receipts—the IRS can ask for them, and your card may get declined at the register even for covered items.
One smart move: schedule any lingering medical appointments now.
That dental crown you've been putting off, the eye exam, the specialist consult—all of it counts.
Booking before the deadline turns procrastination into savings instead of a write-off.
For dependent care FSAs, the rules work similarly, but the deadline pressure hits differently.
If you're paying for daycare, after-school programs, or summer camp, you can claim those dollars, but you need to file the paperwork before the window closes.
The average worker contributes around $1,500 to a health FSA, according to industry data.
Letting even a few hundred dollars lapse is essentially handing your own money back to your employer.
That's not frugal—it's a quiet loss most people never notice until it's gone.
Confirm your exact deadline, your carryover limit, and what's still eligible.
Then spend it deliberately, not in a panic on December 30.
The takeaway is simple: an FSA is only a deal if you use it.
Final Thoughts
Treat the deadline like a bill you actually have to pay—because in a real sense, you already did.
