For 2026, the HSA contribution limit is $4,400 for self-only coverage and $8,750 for family coverage (both up from 2025). The Health FSA limit rises to $3,400, and the Dependent Care FSA limit jumps to $7,500 — its first increase in 25 years. If your workplace’s open enrollment is coming up, here’s exactly what changed, what stayed the same, and how to translate the new limits into a per-paycheck contribution plan.
These figures come from IRS Revenue Procedure 2025-32 (health FSA, HSA, and HDHP figures) and the One Big Beautiful Bill Act, H.R. 1 (dependent care FSA figure), both finalized ahead of the 2026 plan year.
2026 vs. 2025: What Changed
| Account | 2025 limit | 2026 limit | Change |
|---|---|---|---|
| Health FSA | $3,300 | $3,400 | +$100 |
| Health FSA rollover (max carryover) | $660 | $680 | +$20 |
| Dependent Care FSA | $5,000 | $7,500 | +$2,500 |
| HSA — self-only | $4,300 | $4,400 | +$100 |
| HSA — family | $8,550 | $8,750 | +$200 |
| HSA catch-up (age 55+) | $1,000 | $1,000 | No change (not indexed) |
| Commuter/transit (monthly) | $325 | $340 | +$15 |
The Health FSA and HSA figures rise with inflation each year via IRS Revenue Procedure updates, so a $100–$200 bump is typical. The Dependent Care FSA jump is different — that limit was fixed at $5,000 since 1986 and had never been raised for inflation until the One Big Beautiful Bill Act permanently reset it to $7,500 (or $3,750 for married couples filing separately) starting with the 2026 plan year.
HSA Rules You Need Alongside the Limit
An HSA is only available if you’re enrolled in a qualifying High-Deductible Health Plan (HDHP). For 2026, that means your plan’s minimum deductible must be at least $1,700 for self-only or $3,400 for family coverage, and your plan’s out-of-pocket maximum can’t exceed $8,500 for self-only or $17,000 for family coverage. If your plan doesn’t meet these thresholds, you can’t contribute to an HSA even if your employer offers one.
Unlike an FSA, unused HSA funds never expire and the account is yours to keep even if you change jobs or health plans — which is why financial planners often treat an HSA as a secondary retirement account once immediate medical costs are covered, especially since contributions, growth, and withdrawals for qualified medical expenses are all tax-free.
FSA vs. HSA: Quick Comparison
| Health FSA | HSA | |
|---|---|---|
| Requires HDHP? | No | Yes |
| Funds roll over? | Only up to $680 (or grace period, if offered) | Yes — unlimited, indefinitely |
| Ownership | Employer-owned | Employee-owned (portable) |
| 2026 limit | $3,400 | $4,400 / $8,750 |
| Use it or lose it? | Mostly yes | No |
| Can invest unused funds? | No | Yes, with most providers |
If your employer offers both and you’re eligible, you generally can’t max out a full Health FSA and an HSA in the same year — but a Limited Purpose FSA (which only covers dental and vision expenses) is HSA-compatible and lets you set aside up to the same $3,400 limit alongside your HSA.
Turning the Limit Into a Per-Paycheck Number
The IRS limit is an annual maximum, but you elect it during open enrollment as a per-paycheck deduction. To hit the max without over- or under-contributing:
Per-paycheck contribution = Annual limit ÷ Number of pay periods remaining in the plan year
Example: You want to max out your HSA at $4,400 for the year, and you’re paid biweekly (26 pay periods). If your plan year starts January 1 and you enroll on time: $4,400 ÷ 26 = $169.23 per paycheck. If you’re enrolling mid-year with only 15 pay periods left: $4,400 ÷ 15 = $293.33 per paycheck — a noticeably bigger bite out of each check.
This is the same per-period math used for any recurring savings goal — plug your target amount and timeline into the savings goal calculator to see the exact contribution needed, or use the budget calculator to see how a $169–$300 paycheck deduction fits alongside your other expenses before you commit to an election you can’t easily change until next year.
Common Mistakes to Avoid
- Overestimating dependent care costs. Unlike an HSA, unused Dependent Care FSA funds are typically forfeited at year-end (subject to your employer’s grace period or rollover policy, if any) — don’t elect the full new $7,500 unless you’re confident you’ll actually spend it on eligible child or dependent care.
- Forgetting the HDHP requirement. You can only contribute to an HSA if you’re enrolled in a qualifying high-deductible health plan for that coverage period — switching to a non-HDHP mid-year stops your eligibility to contribute (though you can still spend down existing funds).
- Missing the mid-year enrollment math. If you start a new job or have a qualifying life event mid-year, recalculate your per-paycheck amount based on the pay periods actually remaining — using the full-year math will leave you short of (or over) the annual limit.
Frequently Asked Questions
What is the 2026 HSA contribution limit? $4,400 for self-only coverage and $8,750 for family coverage, plus an additional $1,000 catch-up contribution if you’re 55 or older (the catch-up amount is not indexed for inflation).
What is the 2026 FSA contribution limit? The Health FSA limit is $3,400 per employee. The Dependent Care FSA limit is $7,500 (or $3,750 if married filing separately) — up substantially from $5,000 in prior years.
Can I contribute to both an FSA and an HSA in the same year? Generally no for a standard Health FSA, since HSA eligibility requires an HDHP and most standard FSAs are considered disqualifying coverage. However, a Limited Purpose FSA (dental/vision only) or Dependent Care FSA can be paired with an HSA.
Do FSA funds roll over to the next year? Only up to the IRS rollover limit ($680 for 2026), and only if your employer’s plan allows it — otherwise you may have a grace period instead, or lose unused funds entirely at year-end. HSA funds, by contrast, always roll over with no limit.
When do I need to make my election for 2026? During your employer’s open enrollment period, typically in the fall for a January 1 plan-year start — check your specific employer’s dates, since not all plan years run on the calendar year.
The Bottom Line
The 2026 limits give you meaningfully more room to set aside pre-tax dollars: HSA contributors get an extra $100–$200 depending on coverage tier, and anyone using a Dependent Care FSA gets access to $2,500 more than they’ve ever been allowed to contribute. Before you lock in an election during open enrollment, divide your target annual amount by your actual remaining pay periods with the savings goal calculator, and check the resulting paycheck deduction against your full budget with the budget calculator — that way your election is ambitious enough to capture the tax savings, but realistic enough that you won’t feel it every payday.
