2026 Healthcare FSA: Limits, Rollover & Carryover Rules Explained
The 2026 carryover limit is $680. Here is exactly how rollover works, how it differs from the grace period, and how to never lose a dollar of your FSA balance again.
1. The 2026 Contribution Limit
The IRS has set the Healthcare FSA contribution limit for 2026 at $3,400 per employee per year. This is a per-person limit, not per household.
If you and your spouse both have FSAs through different employers, you can each contribute $3,400 — for a combined household total of $6,800 in pre-tax healthcare spending.
2. The 2026 Rollover (Carryover) Rule
The most misunderstood rule in all of benefits administration. Here is exactly how it works.
The IRS allows employers to offer a carryover of up to 20% of the annual contribution limit. For 2026, that calculation is:
What happens to the money above $680?
Any unused balance above $680 at year-end is forfeited to your employer. You cannot roll it over, withdraw it, or transfer it. This is the "Use-It-or-Lose-It" rule — and it applies to everything above the carryover cap.
What happens to rolled-over funds on January 1st?
Rolled-over funds from 2026 become available in your 2027 FSA balance on January 1, 2027. They are treated exactly like new contributions — you can spend them on any eligible expense during the 2027 plan year. They do not count toward your 2027 contribution limit.
What if I leave my job — do I keep the rollover?
No. If you terminate employment before December 31st, your FSA balance — including any potential rollover amount — is forfeited unless you elect COBRA continuation coverage. However, there is an important exception: if you have already spent more than you contributed (which is allowed under the Uniform Coverage Rule), you keep that money. Your employer cannot recover it.
3. Rollover vs. Grace Period vs. Use-It-or-Lose-It
Employers must choose exactly one of these three plan designs. They cannot combine them. Understanding which one your plan uses is critical.
| Plan Design | What It Means | Deadline | Max Saved |
|---|---|---|---|
| Rollover (Carryover) | Up to $680 carries into next plan year automatically | December 31 | $680 |
| Grace Period | Full balance available for 2.5 extra months to spend | March 15 | Full balance |
| Use-It-or-Lose-It | Entire unused balance forfeited at year-end | December 31 | $0 |
On January 1, 2027 — $500 rolls over automatically (under the $680 cap). Nothing is forfeited.
You have until March 15, 2027 to spend the full $500 on eligible expenses. After that, it is forfeited.
4. The FSA Year — Month by Month
Understanding the FSA calendar helps you plan contributions and spending so you never forfeit money unnecessarily.
Open Enrollment — Make Your 2026 Election
Choose your 2026 FSA contribution amount. Review last year's spending to avoid over- or under-contributing. Your election is locked in for the full plan year.
Full Balance Available Immediately
Your entire $3,400 annual election is available on Day 1 — even if you have only contributed a fraction of it. This is the Uniform Coverage Rule and is unique to Healthcare FSAs.
Check Your Balance — Spend-Down Planning
Review your remaining balance. If you have more than $680 left and your plan has a rollover, plan to spend the excess before December 31st to avoid forfeiture.
Plan Year Ends — Rollover or Lose-It
For rollover plans: up to $680 carries over automatically. For grace period plans: your full balance is still available until March 15th. For use-it-or-lose-it plans: anything unspent is forfeited tonight.
Grace Period Deadline (Grace Period Plans Only)
If your plan has a grace period, today is the last day to spend your 2026 FSA balance. After midnight, any remaining funds are forfeited permanently.
