If you have a flexible spending account through work, there's a decent chance a chunk of your own money is sitting in it right now, quietly expiring.
These accounts let you set aside pre-tax dollars for medical or dependent care costs, but they come with a use-it-or-lose-it reputation that has burned plenty of workers before.
With the calendar year winding down, this is the moment to check your balance and your plan's specific rules.
The reason so many people get caught off guard is that the deadline isn't always December 31.
Some employers offer a grace period that stretches into mid-March, while others allow a carryover of a limited amount into the next year.
Your plan might offer one, both, or neither, and the only way to know is to read your benefits paperwork or log into your account portal.
Assuming you have extra time when you don't is an expensive mistake.
Meanwhile, the cost of the things you'd spend that money on keeps climbing.
Medical care services rose again this year, and even over-the-counter staples like pain relievers and allergy pills have crept up.
That's exactly why letting FSA dollars vanish feels worse than it used to.
The same balance buys less than it did a couple of years ago, so every unused dollar is a double loss, since you also gave up the tax savings.
The good news is there's a long list of eligible expenses people forget about.
Prescription glasses and contacts, dental work, hearing aids, bandages, pregnancy tests, sunscreen, and many first-aid supplies typically qualify.
Some plans cover menstrual products and certain breast pumps.
If you've been putting off an eye exam or a dental cleaning, scheduling it before the deadline can soak up a balance fast without spending on anything you don't actually need.
Dependent care accounts work differently and are worth a separate look.
If you pay for daycare, before-school care, or a babysitter so you can work, those dollars may be reimbursable, but the rules are stricter and the deadlines can differ from the medical side.
Parents who mix up the two accounts sometimes miss out on hundreds of dollars they'd already spent.
One more thing to watch: reimbursement claims often have their own filing deadline that lands after the spending deadline.
You might have until late March or April to submit receipts for purchases you made in December, but if you toss the receipt, that money is gone.
Snap a photo of every receipt and upload it the same day.
It takes thirty seconds and saves you a frantic shoebox search later.
If you're staring at a balance you can't possibly spend on real needs, check whether your plan lets you roll some of it over.
If not, a quick restock of eligible everyday items beats forfeiting the cash entirely.
Just don't buy things you'll never use just to hit zero.
Our take: an FSA is one of the few places where a little paperwork genuinely pays you back, but only if you treat the deadline like a real bill.
Put a reminder on your phone today, log in, and find out exactly what you have and when it disappears.
Final Thoughts
Ignoring it doesn't make the money safer, it just makes it someone else's.
