If you have a flexible spending account through work, there's a decent chance a chunk of your own money is sitting there with an expiration date.
These accounts let you set aside pretax dollars for medical or dependent care costs, but many plans require you to spend the balance by December 31.
Miss it, and that money typically goes back to your employer.
The forfeiture rule is the part that catches people every year.
You funded the account through payroll deductions, so it feels like your cash, but the tax break comes with a catch: unused funds can be kept by the company.
Some plans offer a grace period into mid-March, and others let you roll over a capped amount, but those perks are not guaranteed.
Your specific plan documents spell out which rules apply to you.
Start by logging into your benefits portal and checking three things: your current balance, your plan's deadline, and whether a grace period or rollover exists.
Then pull every receipt you've been ignoring.
Copays, prescriptions, eyeglasses, contact lenses, dental work, therapy sessions, bandages, and even some over-the-counter items may qualify.
Dependent care accounts cover daycare, after-school programs, and summer camp, which is easy to forget once the school year ends.
You can't simply order something online on December 30 and call it done.
The expense generally has to be incurred by the deadline, meaning the service happened or the item was purchased before the cutoff.
Shipping delays, backordered glasses, and appointments that slip into January can all wreck your plans.
Book the eye exam and the dental cleaning now, not the week between Christmas and New Year's.
A few practical moves can save you from losing money.
Schedule overdue appointments immediately, since slots fill fast in December.
Refill 90-day prescriptions before the deadline if your plan allows it.
Buy eligible supplies like diabetic test strips, hearing aid batteries, or first aid kits if your account covers them.
And if you're staring down a large leftover balance, ask whether your plan permits using funds for a dependent's eligible expenses, which can widen your options.
One more thing worth checking: whether your employer offers a debit card tied to the account.
Swiping it at the pharmacy counter is far easier than submitting claims and waiting for reimbursement, and it reduces the odds you forget to file before the window closes.
If you don't have one, set a calendar reminder to submit receipts the same day you get them.
The bigger lesson is about how you set your contribution next year.
Underfunding costs you a small tax benefit; overfunding can cost you the entire surplus.
If you consistently leave money behind, lowering your election by a few hundred dollars may be the smarter play.
Our take: an FSA is a useful tool only if you treat the deadline like a real bill.
Final Thoughts
Check your balance this week, book what you've been putting off, and don't let a December scramble donate your paycheck back to your employer.
