Quick Answer
You can roll over up to $640 of unused FSA funds to 2026 (indexed annually). However, your employer must elect this option — it's not automatic. Without rollover, you lose unused funds under the "use-it-or-lose-it" rule, though some employers offer a 2.5-month grace period instead.

How much can you roll over from your FSA?
For 2026, you can roll over up to $640 of unused health FSA funds to the following year — but only if your employer chooses to offer this option. This amount is indexed for inflation and increases slightly each year.
Important: FSA rollover is not automatic. Your employer must elect to offer it, and they can choose between rollover OR a grace period — not both.
Example: $3,000 FSA with $800 remaining
Let's say you contributed $3,000 to your health FSA in 2026 but only spent $2,200 by December 31st. You have $800 left over.

Your three FSA year-end options
Employers can choose one of three options for unused FSA funds:
How to find out your company's policy
1. Check your benefits portal — look for "FSA year-end" or "rollover policy"
2. Ask HR directly — they must disclose which option they've elected
3. Review your FSA enrollment materials from open enrollment
4. Check your most recent pay stub — some companies include FSA balance and policy info
Strategic planning with rollover
If your employer offers rollover, you can be more aggressive with FSA contributions because you're not risking as much money:
Conservative approach (no rollover):
Moderate approach (with rollover):
What you should do
1. Find out your company's policy today — don't wait until December
2. Track your FSA spending throughout the year using your benefits app or receipts
3. Plan year-end spending in November if you're close to the rollover limit
4. Use our [paycheck calculator](paycheck-calculator) to see how FSA contributions affect your take-home pay
If you're approaching year-end with excess funds, consider stocking up on eligible items like bandages, contact solution, or prescription sunglasses.
Key takeaway: FSA rollover lets you keep up to $640 of unused funds, but only if your employer elects this option. Check your company's policy early in the year to plan accordingly.

Key Takeaway: You can roll over up to $640 of unused FSA funds, but only if your employer offers this option instead of a grace period or use-it-or-lose-it policy.
Compare the three FSA year-end options your employer might offer
| Option | Amount You Keep | Deadline | Best For |
|---|---|---|---|
| Rollover | Up to $640 | Automatic Jan 1 | Conservative planners |
| Grace Period | All unused funds | Must spend by March 15 | Good at year-end shopping |
| Use-It-Or-Lose-It | $0 | December 31 | Careful budgeters |

New employees learning about FSAs and worried about losing money
Don't panic — FSA rollover protects you from small mistakes
As a new employee, the FSA "use-it-or-lose-it" rule probably sounds terrifying. Good news: if your employer offers rollover (about 60% do), you can keep up to $640 of unused funds. This makes FSAs much safer for beginners.
Start conservative in your first year
Since you don't know your spending patterns yet:
Example: First-year FSA strategy
Say you're 24, healthy, and estimated $1,500 in annual medical costs:
Without rollover knowledge: You might contribute $1,200 to be safe
With rollover knowledge: You can contribute $1,800-2,000 because worst-case you only lose amounts over $640
The extra $300-500 contribution saves you about $75-150 in taxes (depending on your bracket).
Red flags that mean no rollover
If HR says any of these, your employer doesn't offer rollover:
What to do right now
1. Email or call HR: "Does our company offer FSA rollover, grace period, or use-it-or-lose-it?"
2. Start tracking medical spending even if you haven't enrolled yet
3. Learn what's FSA-eligible — it's more than you think (bandages, thermometers, contact solution)
Key takeaway: FSA rollover makes benefits much safer for new employees — you can contribute more aggressively because you'll only lose amounts over $640, not everything.

Parents managing family healthcare costs and maximizing FSA benefits
Rollover is crucial for family FSA planning
With kids, your medical spending can be unpredictable — one year you might spend $4,000 on braces, another year just $1,500 on routine care. FSA rollover gives you flexibility to contribute more without the fear of losing everything.
Family FSA strategy with rollover
Most families should contribute closer to the maximum ($3,200 for 2026) when rollover is available:
Typical family scenario:
Worst case: You spend only $2,000 and lose $360-560 (amount over $640 rollover)
Best case: You spend $3,200 and save $800-960 in taxes
Don't forget eligible family items
Families often underspend their FSA because they forget about eligible items:
Year-end family FSA shopping strategy
If you have $800+ remaining in November:
1. Stock up on family basics — bandages, children's medicine, thermometers
2. Get eye exams and glasses for family members due for updates
3. Buy a year's worth of contact solution, sunscreen, first aid supplies
4. Consider larger purchases like humidifiers or air purifiers
Remember: You can roll over $640, so you only need to spend the amount above that threshold.
Key takeaway: Families benefit most from FSA rollover because unpredictable kid expenses make conservative contributions risky — rollover lets you contribute aggressively and only lose amounts over $640.
