If you have a flexible spending account through work, there's a good chance a chunk of your own money is quietly ticking toward a cliff right now.
Unlike a savings account, an FSA comes with a use-it-or-lose-it rule, and most plan years wrap up on December 31.
That means any balance left sitting there after the deadline typically goes straight back to your employer.
You funded it with pre-tax dollars all year, so losing it feels less like a fee and more like setting cash on fire.
The average worker elects somewhere in the neighborhood of $1,500 to $2,000 a year, and surveys consistently show a meaningful slice of account holders forfeit at least some of it.
The fix isn't complicated, but it does require a little planning before the calendar flips.
First, check whether your plan has a grace period or a carryover.
Many employers offer a 2.5-month grace window to spend last year's money, while others let you roll a limited amount forward.
The IRS caps that carryover, and it adjusts most years, so confirm your specific plan's rules instead of assuming.
You can often use FSA funds for prescription glasses, contacts, lens solution, and even non-prescription reading glasses.
Dental counts too, which means cleanings, fillings, crowns, and some orthodontia.
Over-the-counter items are where people leave the most money behind.
Since the rules loosened a few years back, you can typically buy bandages, thermometers, pain relievers, allergy medicine, menstrual products, and first-aid supplies without a prescription.
A single drugstore run can wipe out a stubborn balance.
Sunscreen counts as an FSA-eligible product.
So do pregnancy tests, blood pressure monitors, and many breastfeeding supplies.
Some plans even cover travel-sized essentials if they're primarily for medical care.
If you're short on time, you can also book eligible appointments before December 31.
A dental cleaning, an eye exam, or a dermatology visit often does the trick.
Just make sure the service happens before the deadline, not the payment.
One catch worth knowing: your FSA debit card may decline items it can't verify, so save receipts.
If you submit a claim manually, keep documentation in case your plan administrator asks questions later.
A dependent care FSA, used for daycare or after-school programs, runs on its own separate rules and deadline.
Don't assume spending your health FSA balance covers the childcare side.
If you truly can't spend it all, a few plans allow a run-out period into the new year for claims on services already received.
That's not extra time to buy things, just extra time to file paperwork.
Log into your FSA portal this week, check the balance, and confirm your plan's exact deadline and rollover terms.
Then spend deliberately rather than scrambling on December 30.
This is one deadline where procrastination has a real price tag.

A half hour of planning now can keep hundreds of your own dollars from evaporating.
