If you set aside money in a flexible spending account this year, there's a good chance some of it is quietly ticking toward an expiration date.
Unlike a savings account, an FSA is a use-it-or-lose-it arrangement.
Miss the cutoff, and whatever is left typically goes back to your employer.
The catch is that the deadline isn't always December 31.
Many plans offer one of two extensions: a grace period that pushes the cutoff into mid-March, or a carryover that lets you roll a limited amount into next year.
Which one you get depends entirely on your employer's plan design — and you usually can't have both.
That confusion is exactly why so many workers forfeit money every year.
Industry surveys have repeatedly found that a meaningful share of account holders leave hundreds of dollars unspent, often because they assumed the funds would simply roll over like a 401(k).
The good news is that the eligible expense list is far broader than most people realize.
Beyond doctor visits and prescriptions, many plans cover eyeglasses, contact lenses, dental work, hearing aids, bandages, thermometers, and even some over-the-counter medicines.
Since the pandemic-era rules eased, most OTC purchases no longer require a prescription.
So how do you drain the balance without wasting it?
Start by logging into your account portal and checking two numbers: your current balance and your exact plan deadline.
Those two figures tell you how much time and money you're actually working with.
If you wear glasses, a new pair is an easy win.
If you have ongoing dental or vision care, schedule it now rather than waiting.
Stocking a medicine cabinet with eligible items is another simple way to convert the balance into something useful.
One caution: don't buy things you'll never use just to beat the clock.
Spending $200 to save $200 in pre-tax dollars isn't really a win if the items sit in a drawer.
The tax advantage only pays off when the purchase replaces something you'd have bought anyway.
The IRS requires substantiation for FSA claims, and a card swipe alone isn't always enough.
If you're audited or your plan asks for documentation, you'll need to show the expense was eligible and not reimbursed elsewhere.
If you're still unsure, call your plan administrator directly.
Ask whether your plan uses a grace period or a carryover, the exact last day to incur expenses, and the deadline to submit claims — those are often two different dates.
A receipt from March might still need to be filed by April.
For anyone juggling tight budgets, this is real money.
A forfeited balance is effectively a pay cut you volunteered for.
A few minutes of checking now can turn that into groceries, glasses, or a dental visit you were going to need anyway.
The bottom line: an FSA rewards people who plan and punishes people who forget.
Final Thoughts
Treat the deadline like a bill that's due, and you'll rarely lose a dime.
