If you have a flexible spending account through work, there's a decent chance you're sitting on money that will evaporate in a matter of weeks.
Unlike a bank account, an FSA doesn't let you carry a balance forever.
Use it or lose it is the rule, and it's enforced with zero sympathy.
Most people think the deadline is December 31.
But a large share of employers offer either a grace period into mid-March or a carryover of a few hundred dollars into next year — and plenty offer neither.
The only way to know which bucket you're in is to read your plan documents or call your benefits administrator.
Guessing is how people forfeit real money.
The average forfeited amount per person runs somewhere in the low hundreds of dollars, and it adds up to billions industry-wide every year.
It stays with your employer, who can use it to offset the cost of running the plan.
Which means the system is quietly designed so that forgetting is profitable for someone — just not you.
So what actually counts as an eligible expense?
Prescription glasses, contact lenses, dental work, therapy copays, bandages, sunscreen with SPF, menstrual products, and a long list of over-the-counter medicine thanks to a recent rule change.
You generally can't use FSA funds for cosmetic procedures, gym memberships, or most insurance premiums.
You can't just swipe the card and forget it.
If a purchase looks questionable to the administrator, they'll demand a receipt, and if you don't produce one, they can claw the money back and lock your card.
Keep every receipt in a folder or a phone album until the claim clears.
A few practical moves before the clock runs out: log into your account and check the exact balance and deadline today, not next month.
Book the dental cleaning or eye exam you've been delaying.
Stock up on eligible essentials you'll actually use.
And if your plan allows online ordering through an FSA store, that's often the fastest way to spend down a stubborn balance without a scavenger hunt.
Watch out for the scams that sprout up around deadlines too.
Some third-party sites charge a fee to "help" you spend your FSA, or sell marked-up items that are only marginally eligible.
Your plan's own portal and any pharmacy register will do the job.
One more thing worth knowing: if you're married and both spouses have FSAs, you can't double-dip on the same expense.
And if you leave your job mid-year, check whether you can still submit claims for care received before your last day.
Rules vary, and HR isn't always forthcoming.
The uncomfortable truth is that FSAs shift the burden of vigilance onto workers.
You front the money through payroll deductions, then you have to chase it back with receipts before a deadline that many employers bury in onboarding paperwork.
It's a benefit, but it's one that rewards the organized and quietly punishes everyone else.
Final Thoughts
Set a calendar reminder, check your balance this week, and treat that deadline like the real bill it is.
