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 401(k) or an HSA, an FSA generally comes with a use-it-or-lose-it rule, and employers get to decide how strict that clock is.
Here's the wrinkle most people miss: the deadline isn't always December 31.
Some plans offer a grace period that pushes spending into mid-March of the following year, while others allow a carryover of a limited amount into the next plan year.
A third group offers neither, meaning any unspent balance simply goes back to your employer.
The amount you can stash in a health FSA for 2025 sits at $3,200 per employee, and the maximum carryover to 2026 is $660.
Those figures get adjusted most years for inflation, so the exact numbers shift.
The catch is that your specific plan may be more generous or stingier than the federal ceiling, and the only document that matters is your own benefits summary.
Dependent care FSAs play by different rules entirely.
The IRS caps those at $7,500 per household for 2025, and there's no carryover option at all.
If you've been setting money aside for daycare, after-school programs, or summer camp, that balance needs to be claimed before the plan year closes or it's gone.
Doctor visits, prescriptions, dental work, glasses, contact lenses, therapy, and a long list of over-the-counter items that got easier to buy with FSA funds a few years back.
Menstrual products, sunscreen, and certain first-aid supplies now qualify.
Many retailers label FSA-eligible products right on the shelf or in their apps, which makes last-minute spending less of a scavenger hunt.
If you're staring down a balance you can't realistically use in time, there are a few practical moves.
Stock up on eligible staples you'll actually consume.
Schedule that eye exam or dental cleaning you've been putting off.
Buy a spare pair of glasses if your prescription is stable.
Some plans let you submit claims for expenses incurred by the deadline even if you pay for them later, so read the fine print before assuming all is lost.
One more thing worth checking: whether your employer offers a run-out period.
That's a window after the plan year ends during which you can still file receipts for expenses you already incurred.
It doesn't extend your spending deadline, but it does buy you time to submit the paperwork, and plenty of people forfeit money simply because they missed the filing cutoff.
If you're unsure where you stand, log into your FSA administrator's portal today rather than in the last week of the year.
Balances, deadlines, and eligible expense lists are usually right there, and a ten-minute check can be the difference between a few hundred dollars of value and nothing at all.
The uncomfortable truth is that FSA deadlines quietly transfer wealth from distracted workers back to their employers every single year.
Final Thoughts
Set a calendar reminder, check your balance now, and treat that money like the paycheck it already is.
