Yes, leftover FSA rollover money can expire when your plan’s carryover or grace-period deadline passes without eligible spending.
An FSA can feel like free money until the calendar flips and the rules bite. Some plans let you roll a slice of unused funds into the next plan year. Some give you extra time to spend what’s left. Some do neither. The twist is that “rollover” doesn’t mean “yours forever.” It’s still tied to your employer’s plan terms.
This guide explains why rollover funds can still expire, how to find your exact deadline, and what to do in the last few weeks so you don’t donate cash back to the plan.
What Makes FSA Money Expire In The First Place
Most health FSAs follow a “use-it-or-lose-it” structure. You elect an annual amount, the plan sets a plan-year window, and eligible expenses must happen inside that window. If money is left when the window closes, the plan can require forfeiture.
There are two common plan features that shift the ending date:
- Carryover (rollover): your plan may let you bring a limited amount into the next plan year.
- Grace period: your plan may give extra time after plan year-end to incur new eligible expenses.
Plans usually pick one of those two features, not both. IRS rules describe a grace period of up to 2½ months after the plan year ends, and a carryover option that lets a capped amount move into the next year, based on your employer’s plan design. IRS Publication 969 lays out these concepts in plain language.
Do FSA Rollover Funds Expire? What Your Plan Allows
If your employer offers carryover, the carried amount sits in next year’s FSA and follows next year’s rules. That means the carried funds can still be lost later if they remain unused when that next plan year ends. Carryover is a second chance, not a forever bucket.
If your employer offers a grace period, unused funds from the prior year stay available for a short extension after the plan year ends, then any remaining amount is forfeited once the grace period ends.
Carryover, Grace Period, And “Run-Out” Are Three Different Clocks
People often mix these up because all three show up near year-end:
- Carryover: moves a limited dollar amount into the next plan year for new spending in that year.
- Grace period: extends the prior plan year’s spending window by a limited number of months.
- Run-out period: extra time to file claims for expenses that already happened in the plan year (or grace period, if your plan has one). A run-out window does not extend when you can incur expenses.

Why “Rollover” Still Expires
Carryover feels like a safety net, so it’s easy to think the dollars are protected. They aren’t protected from the next deadline. If you carry over $500 into a new plan year and then end that new year with $500 still sitting there, the plan can forfeit it the same way it forfeits any unused balance at year-end.
Carryover is optional for employers. Two coworkers at different companies can see totally different outcomes even with the same FSA election.
How To Find Your Exact FSA Rollover Deadline
Your plan’s deadline is written in the plan materials. Here are the fastest places to locate it:
- Summary Plan Description (SPD) or plan booklet: look for sections named “health FSA,” “carryover,” “grace period,” and “claims filing.”
- Your FSA portal dashboard: many administrators show a “use by” date and a “submit claims by” date.
- HR benefits email or open enrollment materials: the annual reminder often lists the carryover cap and the last date to incur expenses.
- The plan administrator: ask for the plan-year end date, whether the plan uses carryover or a grace period, and the claim filing deadline.
Watch For Non-Calendar Plan Years
Plenty of FSAs run January through December. Some run on a fiscal year like July through June. If your plan year ends June 30, your deadlines will land in late summer or early fall, not in December.
Once you know your plan-year end, map the three dates that matter:
- Last day to incur eligible expenses (plan year end or grace-period end)
- Last day to submit claims (end of run-out period)
- Carryover amount and where it appears (new plan year balance line)
Some official programs publish clear claim deadlines that show how strict these cutoffs can be. The federal FSA program posts annual reminders on its message board. FSAFEDS claims deadline notice is one concrete illustration of a hard “received by” date.
FSA Rollover Funds Expiration Rules By Plan Feature
Use this table as a checklist for what to verify in your plan materials. It’s built to help you avoid the two most common mistakes: spending too late and filing too late.
| Plan Detail To Verify | What It Usually Means | What You Should Confirm |
|---|---|---|
| Plan year dates | Defines your spending window | Is it Jan–Dec or another cycle? |
| Carryover offered | A limited amount moves into next year | Carryover cap for your plan year |
| Grace period offered | Extra time to incur new expenses | Exact end date of the grace period |
| Carryover vs grace period | Plans often choose one | Which option is active this year? |
| Run-out period length | Time to submit claims after spending ends | Final “submit by” date for receipts |
| Eligible expense timing | Expense date must fall in the window | Service date vs purchase date rules |
| Debit card proof rules | Receipts may be requested after swipes | How long you must keep proof |
| Termination rules | Job changes can shorten access | Whether COBRA or run-out applies |
| Rollover posting date | Shows when carryover appears next year | When the carried funds become visible |
How Carryover Amounts Work And Why The Cap Matters
Carryover is not automatic in the sense of “the IRS gives it to you.” Your employer must adopt it in the plan terms, and the plan can set a cap up to the IRS limit for that plan year.
If you’re reading older posts, watch the year. The carryover limit is indexed and can change over time. When your plan administrator tells you the cap, ask which plan year it applies to and whether it matches the IRS maximum.
For special relief years, rules can differ. IRS Notice 2021-15 described temporary flexibility tied to pandemic-era legislation, including carryover rules for certain plan years. IRS Notice 2021-15 is the primary document on that topic.
Carryover Does Not Change What Is Eligible
Carryover changes timing, not eligibility. If an item is not an eligible medical expense under your plan, carryover money doesn’t make it eligible. Your administrator’s eligible expense list is still the rulebook for what gets reimbursed.
Common Reasons People Lose Rollover Money
Most forfeitures happen for simple reasons.
They Spend After The Spending Window Ends
Buying eligible items after the deadline won’t help if the service date falls outside the plan window. A receipt dated the next day can mean zero reimbursement.
They File After The Run-Out Date
Even if you incurred the expense in time, a late claim can be denied. Set a reminder for the claim deadline, not just the spending deadline.
They Change Jobs And Miss The Tighter Deadline
When you leave an employer, access to the FSA can end sooner than you expect. Some plans give a short run-out to file claims for expenses that happened while you were on the plan. Some offer a way to extend access through COBRA. Your SPD will spell out your plan’s rules.
Smart Spending Options In The Last 30 Days
When the deadline is near, you want spending that is clearly eligible, easy to document, and useful in your life.
Schedule Care With Known Costs
- Dental cleanings, fillings, or orthodontic visits already planned
- Vision exams, glasses, contact lenses, lens solution
- Prescription refills and common copays
Buy Daily Eligible Health Items
Many plans reimburse common health items and first-aid supplies. Check your administrator’s eligibility list before you spend, then keep itemized receipts.
End-Of-Year Checklist To Protect Your Balance
This routine saves money because it fights the two deadline traps: spending too late and filing too late.
- Log into your FSA portal and write down your current balance.
- Find the last day to incur expenses and the last day to submit claims.
- Pick two or three eligible expenses you can complete before the spending deadline.
- Pay, save receipts, and upload claims within a week.
- Recheck your balance after reimbursements post.
| Timing Point | What To Do | Proof To Save |
|---|---|---|
| 60–45 days before spending ends | Review balance and deadlines; book appointments | Screenshot of plan dates |
| 45–30 days before spending ends | Plan purchases tied to needs (contacts, supplies, copays) | Itemized receipts |
| 30–14 days before spending ends | Finish appointments; confirm service dates fall inside the window | Provider invoice |
| 14–1 days before spending ends | Submit claims you already have; track approvals | Claim confirmations |
| After spending ends, during run-out | Submit remaining claims for in-window services | Receipts plus EOB, if asked |
| New plan year start | Check whether carryover posted and how it’s labeled | Portal screenshot of new balance |
If You Missed The Deadline
If the spending window ended and your plan requires forfeiture, there may be no fix. Administrators must follow the written plan terms.
Use the miss as data for next year: lower your election if you consistently leave money behind, and set recurring reminders for both deadlines as soon as open enrollment ends.
