What is FSA Rollover?
FSA rollover allows you to carry unused Flexible Spending Account funds from one plan year to the next, avoiding the traditional "use-it-or-lose-it" forfeiture. The IRS permits employers to choose one of three rollover options (but not both): (1) $640 carryover (2025 limit, 20% of contribution max), (2) 2.5-month grace period (spend until March 15), or (3) no rollover (strict December 31 deadline).
2025 FSA Contribution Limits
| FSA Type | 2025 Limit | Max Carryover | Notes |
|---|---|---|---|
| Healthcare FSA | $3,200 | $640 (20%) | Medical, dental, vision expenses |
| Dependent Care FSA | $5,000 | $0 (Not eligible) | Daycare, nanny, elder care |
*Dependent Care FSA does NOT have carryover or grace period options—it's strict use-it-or-lose-it by December 31.
Carryover vs. Grace Period Comparison
$640 Carryover (2025)
- • Maximum $640 rolls to next year
- • Excess amount forfeited
- • No deadline extension
- • Carried funds available Jan 1
- • Can combine with new election
2.5-Month Grace Period
- • All remaining funds available
- • Spend until March 15 next year
- • Forfeit if not used by deadline
- • Claims must incur during grace
- • Cannot combine with carryover
How Rollover Works: Example
Scenario: $1,500 Balance on Dec 31, 2025
- • Must spend $1,500 by Dec 31, 2025
- • Forfeit entire $1,500 if not used
- • Lose $445 in tax savings (29.65% rate)
- • Must spend $860 by Dec 31, 2025 (excess)
- • $640 rolls to 2026 (available Jan 1)
- • Forfeit $860 if not spent ($255 tax loss)
- • Full $1,500 available until March 15, 2026
- • Additional 2.5 months to spend
- • Forfeit any unused after March 15
Strategic FSA Planning Tips
- Front-load big expenses: Schedule surgeries, dental work, or vision care early in the year when full FSA balance is available.
- Stock up on eligible items: Buy year's supply of contacts, OTC meds, first aid supplies, sunscreen (SPF 15+).
- Use FSA store websites: FSAstore.com, HSAstore.com automatically filter eligible products.
- Check employer's policy: Confirm if you have carryover, grace period, or neither—plan accordingly.
- Dependent Care timing: No rollover! Precisely estimate daycare costs; under-elect if unsure.
- Mid-year election changes: Only allowed for qualifying life events (marriage, birth, job change).
- Reimbursement deadlines: Separate from spending deadline—typically 90 days after plan year (March 31 for Dec 31 year-end).
Frequently Asked Questions
1. What happens to unused FSA funds if I don't have rollover or grace period?
Under the strict use-it-or-lose-it rule, any FSA funds not spent by December 31 are forfeited—you lose the money permanently. Your employer keeps the forfeited funds (they cannot return them to you per IRS rules). This means if you elected $3,000 but only spent $2,000, you forfeit $1,000 plus the ~$300 in tax savings (29.65% effective rate). To avoid forfeiture, track your balance monthly and spend aggressively in Q4 (stock up on eligible items, schedule appointments).
2. Can I carry over more than $640 if my employer allows it?
No. The $640 carryover limit (2025) is set by the IRS, not your employer. Even if your employer wanted to allow $1,000 carryover, they legally cannot exceed the IRS cap (which is indexed to inflation—it was $610 in 2023, $640 in 2024-2025). Any balance above $640 must be forfeited if you have a carryover plan. The only exception is the grace period option, which allows carrying the entire balance for 2.5 months—but this is an alternative to carryover, not in addition to it.
3. How does the grace period work exactly?
The 2.5-month grace period extends your FSA deadline from December 31 to March 15 of the following year. During this window, you can incur and submit claims for new eligible expenses (not just submit old claims—the service date must be Jan 1–March 15). All remaining funds are available (no $640 cap), but anything not used by March 15 is forfeited. Example: $2,000 balance on Dec 31 → you have until March 15 to spend it on doctor visits, prescriptions, or eligible purchases occurring in Jan–March.
4. Does Dependent Care FSA have carryover or grace period?
No. Dependent Care FSA follows strict use-it-or-lose-it rules with no carryover and no grace period options. All $5,000 (2025 limit) must be spent by December 31 on qualifying expenses incurred during that calendar year. This makes Dependent Care FSA riskier than Healthcare FSA—if you over-elect (e.g., your nanny quits or child starts school mid-year), you forfeit the excess with no rollover safety net. Conservative election strategy: Elect 10-15% below expected costs to avoid forfeiture.
5. Can I change my FSA election mid-year to avoid forfeiture?
Generally no. FSA elections are locked in at open enrollment and cannot be changed unless you experience a qualifying life event (QLE): marriage, divorce, birth/adoption, dependent death, spouse job change, work schedule change (part-time↔full-time), or COBRA/Medicaid gain/loss. Even with a QLE, changes must be "consistent" with the event (e.g., birth of child allows increasing Dependent Care FSA). You cannot reduce your election just because you over-estimated expenses—you're stuck with the forfeiture risk unless you find ways to spend the balance.
6. What's the deadline to submit claims for reimbursement?
The runout period (claims submission deadline) is separate from the spending deadline. Most plans allow 60-90 days after plan year end to submit claims for expenses incurred during the plan year. For a calendar-year FSA with no grace period: (1) Expenses must occur by Dec 31, 2025; (2) You have until ~March 31, 2026 to submit receipts. If you have a grace period: Expenses incurred Jan 1–March 15 can typically be submitted until June 30. Check your Summary Plan Description (SPD) for exact deadlines—missing the runout forfeits reimbursement even for valid expenses.

Frequently Asked Questions
How much FSA money can I roll over to 2025?
For 2025, the maximum FSA carryover is $640 (20% of $3,200 limit). This applies only to Healthcare FSAs. Important: Employers choose between carryover OR 2.5-month grace period, not both. Dependent Care FSAs have no carryover - use it or lose it by December 31. Check your plan documents to confirm which rule your employer uses.
What is the FSA grace period and how does it work?
The grace period allows 2.5 months (through March 15) to spend previous year FSA funds. If your employer offers grace period instead of carryover, you can spend remaining 2024 funds until March 15, 2025. Funds spent during grace period count against previous year balance first, then current year. Most plans offer either grace period OR carryover, rarely both.
What happens to FSA money I do not use by year end?
Unused FSA funds are forfeited under the use-it-or-lose-it rule, except for: $640 carryover if employer allows, OR grace period spending (through March 15), OR run-out period claims (typically 60-90 days for previous year expenses). Forfeited money returns to employer, not to you. Plan carefully to avoid forfeiture - average American loses $339/year.
Can I change my FSA contribution mid-year?
Generally no, except for Qualifying Life Events (QLEs): marriage, divorce, birth/adoption, dependent age-out, employment status change, significant cost/coverage change. Must request change within 30-60 days of QLE. Change must be consistent with event. No changes allowed just because you over/under-contributed. Front-load spending if expecting QLE or job change.
What expenses are eligible for FSA reimbursement?
Healthcare FSA covers: copays, deductibles, prescription drugs, dental/vision care, glasses/contacts, medical equipment, some OTC medications (with prescription), orthodontia, therapy/counseling. Not covered: insurance premiums, cosmetic procedures, vitamins. Dependent Care FSA covers: daycare, preschool, before/after school programs, summer day camps (not overnight). Check IRS Publication 502 for complete list.
Should I max out my FSA or be conservative?
Calculate predictable annual expenses first: monthly prescriptions, planned procedures, copays, known dental/vision work. Add 15% buffer for unexpected costs. Healthcare FSA 2025 limit: $3,200. Example: $200/month prescriptions + $500 glasses + $1,000 dental = $3,900 needed but only contribute $3,200 maximum. Better to under-contribute slightly than forfeit money - 29.65% tax savings not worth forfeiture risk.
