There's a deadline looming for millions of American workers that has nothing to do with taxes, and missing it means watching your own money vanish.
It's the flexible spending account cutoff, and if you don't spend what you set aside by December 31, your employer keeps it.
Roughly 14 million households use a healthcare FSA, and the average worker elects somewhere around $1,500 to $2,000 a year, according to industry surveys.
The math on forfeitures is ugly: estimates put unspent FSA dollars in the hundreds of millions annually.
That's real money pulled straight from paychecks, pre-tax, and quietly surrendered.
You chose your contribution last fall during open enrollment, before you knew about the surprise dental crown or the specialist copays.
Or the opposite happened — you stayed healthy, skipped the optometrist, and now it's mid-December with a balance sitting there like a gift card you forgot you owned.
The good news is that spending it down isn't hard if you know where to look.
FSA funds cover far more than doctor visits: prescription glasses and sunglasses, contact lenses and solution, bandages, thermometers, blood pressure monitors, acne treatments, sunscreen SPF 15 and up, feminine products, breast pumps, and even some over-the-counter cold medicine if your plan allows it.
Many stores mark FSA-eligible items right on the shelf tag, and Amazon and Walmart both have dedicated FSA storefronts that filter the guesswork.
Dental and vision work is the big-ticket move.
If you've been putting off that cleaning, filling, eye exam, or new pair of glasses, December is the moment.
You can also prepay for eligible services in January if your provider allows it — check first, because rules vary by plan.
Two safety valves exist, but don't count on them.
Some employers offer a grace period until March 15, and others allow a carryover of up to $640 into next year, per IRS limits.
Your plan might offer one, both, or neither.
The only way to know is to read your benefits summary or call your FSA administrator.
You can't just swipe the card and forget it.
The IRS requires substantiation, and administrators routinely audit claims months later.
If you bought a $60 "wellness" item that doesn't actually qualify, you may have to pay it back — with tax consequences.
Keep every receipt in a folder or a phone album labeled by date.
One more trap: dependent care FSAs run on a separate clock and a separate rulebook.
If you set aside money for daycare or after-school care, you generally must incur the expense by December 31, and you can't use leftover funds on random purchases.
Unused dependent care money is the hardest to recover.
If you're staring at a balance with weeks to go, start with the guaranteed wins: refill prescriptions, book the eye exam, replace the glasses, stock the medicine cabinet.
Every dollar you spend is a dollar you already earned.
The real takeaway is that FSAs reward planners and punish procrastinators.
If the deadline stress hits you every single year, it may be worth lowering your election next open enrollment to an amount you know you'll actually use.

A smaller tax break beats a guaranteed loss.
