Millions of American workers are staring down a deadline that most of them forgot about entirely.
If you set aside money in a flexible spending account this year, that cash may vanish at midnight on December 31 unless you spend it first.
Unlike a savings account, an FSA is a use-it-or-lose-it arrangement, and your employer keeps whatever you leave behind.
The average household contributes somewhere between $1,500 and $2,700 to a healthcare FSA, and surveys consistently show that a meaningful chunk of participants forfeit part of it.
That's money that came out of your paycheck, tax-free, and simply evaporated.
There's one wrinkle worth knowing: many employers offer a grace period of up to two and a half months, or let you carry over a limited amount into the next year.
But those rules are set by your plan, not by the IRS mandate.
If you're not sure which camp you're in, your HR portal or benefits administrator has the answer in about two minutes.
The practical move is to stop thinking of this as a tax form and start treating it like a gift card with an expiration date.
Eligible expenses go well beyond doctor visits.
Prescription glasses, contact lenses, dental work, therapy, bandages, pregnancy tests, sunscreen, and even some over-the-counter medications qualify, depending on your plan.
A dependent care FSA, a separate bucket, covers day care, after-school programs, and summer camp.
One efficient trick: many FSA administrators run online stores where you can stock up on eligible items in a single transaction.
Bandages, thermometers, first-aid kits, and pain relievers can absorb a few hundred dollars fast.
You can also prepay for upcoming appointments or buy a year's supply of contact lenses before the clock runs out.
If you're also funding a health savings account, that HSA is the more flexible tool because balances roll over indefinitely.
The trade-off is that HSA eligibility generally requires a high-deductible health plan, so switching mid-year usually isn't an option.
The real design flaw is that FSAs punish the people who need them most.
If you're healthy and underspent, you lose.
If you're sick and overspent, you're covered, but only up to what you elected.
The system rewards accurate forecasting, which is a strange thing to demand from anyone navigating American healthcare costs.
Treat your FSA balance like a perishable good, not a rainy-day fund.
Spend an hour this week reviewing what's left, check your plan's grace period rules, and unload it on things you'll genuinely use.
Final Thoughts
The deadline doesn't care about your intentions, only your receipts.
