2026 HSA contribution limits
The IRS raises HSA limits each year to keep pace with inflation. The 2026 limits are set in Revenue Procedure 2025-19, published in May 2025[1]. Self-only coverage allows $4,400 in contributions, up $100 from 2025's $4,300. Family coverage allows $8,750, up $200 from 2025's $8,550.
| 2026 limit | Self-only | Family |
|---|---|---|
| Contribution limit | $4,400 | $8,750 |
| Catch-up (age 55+) | +$1,000 | +$1,000 |
| HDHP minimum deductible | $1,700 | $3,400 |
| Out-of-pocket maximum | $8,500 | $17,000 |
The catch-up contribution is worth calling out separately: it is a fixed $1,000 that does not rise with inflation, and it applies to the account holder, not the plan[2]. If you and a spouse are both 55 or older, each of you can add $1,000 — but you need separate HSAs to do it.
What an HSA actually is
An HSA is a tax-advantaged account you can open when you're covered by a high-deductible health plan. You — or your employer — put money in, it grows tax-free, and you can withdraw it tax-free for qualified medical expenses[2]. Unlike a flexible spending account, the money is yours to keep: it rolls over year after year with no use-it-or-lose-it rule, and it follows you if you change jobs or retire[2].
You're eligible if you're covered by an HDHP, are not enrolled in Medicare, and cannot be claimed as a dependent on someone else's return. A "high-deductible" plan means exactly what the table above says: a deductible of at least $1,700 for self-only coverage or $3,400 for family, and out-of-pocket costs capped at $8,500 or $17,000 respectively[1]. If your plan has a lower deductible, you generally cannot contribute to an HSA.
Why it's called a triple tax advantage
The HSA is the only account that gets three distinct tax breaks at once[2]:
- Deductible going in. Your contributions lower your taxable income, even if you don't itemize deductions.
- Tax-free growth. Interest, dividends, and capital gains inside the account are not taxed while they stay there.
- Tax-free coming out. Withdrawals used for qualified medical expenses are never taxed.
That combination beats a traditional IRA (deductible now, taxed later) and a Roth IRA (taxed now, tax-free later) on paper — but only if you actually use the money for medical costs. Most accounts give you two of the three; the HSA is the only common one that can give you all three.
HSA vs. FSA: the key differences
Both accounts cover medical costs with pre-tax dollars, but they behave very differently. The 2026 health FSA limit is $3,400[3] — below even the HSA self-only limit — and most FSAs come with a use-it-or-lose-it rule that forfeits unspent money at year-end.
| Feature | HSA | Health FSA |
|---|---|---|
| 2026 contribution limit | $4,400 / $8,750 | $3,400 |
| Rolls over year to year? | Yes, unlimited | Mostly no |
| Yours if you leave your job? | Yes | No |
| Can you invest it? | Yes | No |
| Requires an HDHP? | Yes | No |
Using your HSA for the long term
Because the balance rolls over indefinitely, many people use an HSA as a stealth retirement account. You can invest the funds in stocks, bonds, or mutual funds, and let the growth compound tax-free[2]. The optimal strategy for many: contribute the max, pay small medical bills out of pocket, and let the account grow untouched.
There is a catch if you withdraw for non-medical reasons before 65: the withdrawal is taxed as income and hit with a 20% penalty[2]. After 65, non-medical withdrawals are taxed as ordinary income but the penalty disappears — making an HSA after 65 function much like a traditional IRA for non-medical spending, while still being tax-free for medical costs.
FAQ
Who can contribute to an HSA?
You need to be covered by a qualifying HDHP, not be enrolled in Medicare, and not be claimable as a dependent. Your HDHP must meet the deductible and out-of-pocket thresholds for the year — $1,700/$3,400 deductible and $8,500/$17,000 out-of-pocket max for 2026[1].
What counts as a qualified medical expense?
Doctor visits, prescriptions, dental and vision care, and many out-of-pocket costs qualify. The IRS maintains the full list in Publication 502. Over-the-counter medicines and menstrual products are also eligible without a prescription.
Can I have an HSA and an FSA at the same time?
Generally no, unless the FSA is a "limited-purpose" FSA restricted to dental and vision. A standard health FSA is disqualifying coverage because it pays first-dollar medical costs, which undermines the HDHP requirement.
What if I over-contribute?
Excess contributions are subject to a 6% excise tax each year they remain in the account. You can avoid it by withdrawing the excess (and its earnings) before your tax-filing deadline, including extensions.
