IRS Revenue Procedure 2024-40
An FSA is a payroll deduction that happens silently. Your contribution comes out of every paycheck before you see it, and the balance accrues in an account you almost never log into. No bill arrives. No app pings you in August asking if you've used any of it.
Most people remember the account exists twice a year: during open enrollment, when they estimate next year's contribution, and in late December, when a coworker mentions the deadline. By then, the usable window is two weeks, half the FSA Store is backordered, and your dentist has nothing available until February.
The result is a benefit that exists on paper but quietly converts itself back into employer revenue every year. A reminder set in October or November is the simplest way to stop that from happening to you.
A useful FSA reminder fires weeks before the deadline, not at it. You need time to book an appointment, order eligible products, or schedule procedures that your provider might not have open for another month.
Check your benefits portal or plan summary. Most FSAs end December 31, but some employers run July–June or April–March plan years.
For a December 31 deadline, pick mid-November. You'll have time to book real appointments, not just last-minute online orders.
BoldRemind keeps nudging until the task is actually complete. One email that disappears after you scroll past it is not a reminder — it's a coin flip.

Set one for mid-November and another for early December. The first gives you six weeks to book medical appointments and order eligible products. The second is a last-call nudge while there is still time to reach an in-stock FSA store. Waiting until December 26 to check your balance rarely ends well.
Most FSA deductions happen automatically through payroll, so participants rarely see their balance day to day. There is no monthly bill, no app notification, no account login built into daily life. The money sits silently until the plan year ends and the employer sends a forfeiture notice in January.
According to FSA Store and industry research, roughly 40 percent of FSA participants forfeit some portion of their annual contribution, with average forfeitures in the $170 to $340 range per person. Across all FSA accounts, that adds up to hundreds of millions of dollars returned to employers every plan year.
No. You set your own reminder date based on when your plan year ends. Most FSAs use a December 31 deadline, but some employers run non-calendar plan years ending in June or March. Check your plan documents or benefits portal for the exact date before setting your reminder.
Unused balances above any carryover limit your employer allows are forfeited back to the employer. The money is gone — there is no appeal, no rollover by default, and no tax deduction for the lost amount. This is the IRS use-it-or-lose-it rule, and it is strictly enforced.
Usually not, unless you elect COBRA continuation for the FSA. Most employers terminate FSA eligibility on your last day, and any claims must be for expenses incurred before that date. Runout periods let you file claims late, but you cannot incur new expenses once coverage ends.
Free. No account. Takes 30 seconds. An email before your FSA deadline — and follow-ups until you've actually spent the balance.
