If you have a flexible spending account through work, there's a countdown running that most people ignore until it's too late.
The money you set aside for 2025 has to be spent by a certain date, or you forfeit whatever's left.
Unlike a bank account, an FSA doesn't let your balance sit there earning interest while you figure it out.
Most plans require you to spend the funds by December 31, but many employers offer a grace period that pushes it to March 15 of the following year.
Some plans instead allow a carryover of a limited amount, which the IRS set at $640 for 2025.
Your employer picks grace period or carryover, and plenty of workers don't know which one applies to them.
The stakes are real because FSA money is use-it-or-lose-it.
If you elected $2,000 and only spent $1,400, that missing $600 doesn't come back to you.
It stays with your employer, who can use it to offset plan costs.
That's not a scam, exactly, but it's a rule most people learn the hard way.
The good news is that the eligible expense list is wider than people assume.
Doctor visits, prescriptions, glasses, contacts, dental work, therapy, and many over-the-counter items qualify.
You can also stock up on bandages, thermometers, first-aid kits, and menstrual products without a prescription.
So do some pregnancy tests and blood pressure monitors.
You can't just swipe your FSA card in late March and expect it to clear.
The expense has to be incurred by the deadline, even if you submit the receipt afterward.
A January dentist appointment won't help you if your plan ended December 31.
One move people miss: you can often use FSA funds for dependents who aren't on your health insurance, as long as they qualify as a tax dependent.
That means a child's braces or a spouse's contact lenses might be fair game even if they're covered under a different plan.
If your employer offers a dependent care FSA for daycare or after-school programs, that deadline usually matches the health FSA.
But the rules are separate, and the carryover doesn't apply the same way.
The smartest play right now is to log into your benefits portal and check three things: your remaining balance, your plan's exact deadline, and whether your employer chose a grace period or a carryover.
Then look at what you already know you'll need in the next few months.
Refill prescriptions early, book that eye exam, replace the expired EpiPen.
If you're close to the finish line, a dental cleaning or a pair of prescription sunglasses can close the gap.
Reimbursement systems get slammed, receipts get lost, and cards get declined.
The system is built so that forgetting feels normal, but a fifteen-minute check can keep hundreds of dollars from vanishing.
Final Thoughts
Set a reminder now, and treat the deadline like a bill you actually want to pay.
