There's a deadline approaching that could quietly cost American workers hundreds of dollars, and most people won't notice until it's too late.
Flexible Spending Account funds from 2024 typically must be spent by December 31, or account holders risk forfeiting whatever balance remains.
FSAs let employees set aside pre-tax dollars for medical or dependent care expenses, lowering their taxable income throughout the year.
The catch is the "use it or lose it" rule — money left in the account after the deadline generally goes back to the employer, not the worker.
The average employee contributes roughly $1,500 to a healthcare FSA, according to industry data, though limits for 2025 sit at $3,300 per person.
That means an unspent balance can represent a real hit to a household budget already stretched by higher grocery bills, rent, and insurance premiums.
Some employers offer a grace period extending into mid-March, while others allow a carryover of up to $660 into the next plan year.
Workers should check their specific plan documents rather than assume either option applies.
For those staring down a balance, there are practical ways to zero it out before the clock runs out.
Vision and dental expenses often qualify, including new glasses, contact lenses, exams, and cleanings.
So do prescription medications, insulin, and many over-the-counter items if a doctor provides a letter of medical necessity.
Scheduling medical appointments now can also help.
Copays for a dermatologist visit, a physical therapy session, or a flu shot all count.
Some plans even cover sunscreen, bandages, and menstrual products thanks to recent federal changes.
Dependent care FSAs operate on a separate track with their own rules and a $5,000 household limit for 2024.
Parents who paid for daycare, after-school programs, or summer camp may still have eligible expenses to claim, but the paperwork has to match the calendar year.
Missing the deadline doesn't just waste money — it can also mean losing the tax break you were counting on.
Every dollar forfeited was money that could have covered a copay or a prescription refill instead of vanishing from the account.
A quick check of your FSA portal takes five minutes and could save you a few hundred dollars.
Log in, review the balance, and either book that appointment or submit those receipts before the year closes out.
It's one of the few financial moves where acting fast has an obvious payoff.
The bottom line: an FSA deadline is easy to ignore until it isn't, and the money doesn't roll over just because life got busy.
Treat the remaining weeks like a mini budget challenge — spend what you set aside, or at least confirm how much your plan actually lets you keep.
Final Thoughts
A little paperwork now beats watching your own paycheck evaporate in January.
