If you have a flexible spending account through your job, there's a decent chance a chunk of your own money is sitting in it right now, quietly running out of time.
These accounts let you set aside pre-tax dollars for medical or dependent care costs, but they come with a catch that trips up millions of Americans: use it or lose it.
The rules sound simple until you actually try to follow them.
You elect an amount during open enrollment, money comes out of each paycheck, and you're supposed to spend it on eligible expenses by the end of the plan year.
Miss that window and the leftover balance typically goes back to your employer.
Not every plan runs on the calendar year, and not every employer offers the same grace period.
Some allow a 2.5-month extension into the following March.
Others offer a carryover that lets you roll a limited amount forward.
The only way to know which bucket you're in is to read your plan documents or call your benefits administrator, because guessing wrong is expensive.
The good news is that eligible spending is broader than most people assume.
Prescription glasses, contact lenses, and solution count.
So do bandages, thermometers, blood pressure monitors, and many over-the-counter medications if your plan allows them without a prescription.
Sunscreen, acne treatments, and even some menstrual products qualify.
Dental work, therapy copays, and hearing aids are usually fair game too.
Dependent care accounts work differently and deserve their own warning.
If you set aside money for daycare or after-school programs, those funds often have a separate deadline and separate rules.
A lot of parents assume the two accounts share a timeline.
First, log into your benefits portal and find your actual balance and your actual deadline.
Second, check whether your plan allows a grace period or carryover, since that changes your urgency level.
Third, if money is expiring, schedule the appointments you've been putting off, stock up on eligible essentials, or submit those receipts you never got around to filing.
One more thing worth knowing: reimbursement deadlines are often later than spending deadlines.
You may be able to incur a cost in December and still submit the claim in January or February.
People leave real money behind because they confuse the two dates.
If you're staring at a balance you can't possibly spend in time, ask your HR team whether a run-out period applies, and consider adjusting your election next open enrollment.
The goal is to capture the tax break without overfunding an account you can't drain.
The system isn't designed to be intuitive, and that's exactly why so many people lose money to it every year.
Treat your FSA like a bill with a due date, because functionally, that's what it is.
Final Thoughts
A few minutes in your benefits portal this week could be worth hundreds of dollars.
