Millions of American workers are staring down a deadline that quietly drains bank accounts every year: the flexible spending account cutoff.
Money set aside for medical expenses doesn't roll over indefinitely, and whatever is left when the clock runs out typically vanishes.
For 2024 plan years, most employers require balances to be spent by December 31.
Miss it, and that cash is gone—no refund, no credit, no appeal.
The stakes are bigger than most people realize.
The average FSA contribution runs well over $1,000 a year, and surveys consistently show a large share of account holders forfeit at least some of it.
That's real money evaporating from household budgets already squeezed by grocery bills and rent.
The rules aren't uniform, which is where people get tripped up.
Some employers offer a grace period lasting until March 15 of the following year, letting you spend last year's funds a little longer.
Others use a carryover, allowing a limited amount—currently capped around $640 for 2024—to roll into the next plan year.
You have to check your specific plan documents or benefits portal to know which applies.
There's also a crucial distinction between account types.
Healthcare FSAs carry the use-it-or-lose-it risk.
Dependent care FSAs follow separate rules and generally don't offer a grace period or carryover at all.
If you're juggling both, treat them as two separate deadlines.
So what actually counts as an eligible expense?
Over-the-counter medications have been reimbursable without a prescription since 2020.
That includes pain relievers, allergy pills, cold medicine, and menstrual products.
Bandages, first-aid kits, thermometers, blood pressure monitors, and even some sunscreen qualify.
Prescription glasses, contact lenses, and solution are covered.
Dental work, copays, and deductibles count too.
The smartest move is to schedule appointments now rather than in late December, when dentist and optometrist calendars fill up fast.
If you wear glasses or contacts, get that eye exam and order a year's supply.
Stock the medicine cabinet with eligible items while you can still be reimbursed.
Timing matters for another reason: reimbursements.
If you swipe your FSA card on December 31, the charge needs to be for a service or product received by the deadline—not just ordered.
Some plans allow expenses incurred through the grace period but require claims submitted weeks later, so don't wait until the final days to file.
Audits happen, and a denied claim after the deadline is nearly impossible to reverse.
The forfeiture problem is a feature of how these accounts are designed, not a glitch.
Employers and administrators benefit when workers overestimate their spending and underuse their balances.
That asymmetry puts the burden on you to track your own money like a hawk.
Our take: if you have an FSA, log into your account today—not next month—and see exactly what's left.
Then build a short list of eligible purchases and appointments you can knock out before the cutoff.
Final Thoughts
A little planning now beats watching your own money disappear on January 1.
