🎯 In 30 seconds: A Health Savings Account lets you put money in before tax, invest it, and take it out tax-free for medical costs. No other account gets all three breaks. For 2026 you can contribute up to $4,400 with self-only coverage or $8,750 with family coverage, if you are covered by a qualifying high-deductible health plan.
Who can open one
You need to be covered by a high-deductible health plan (HDHP), have no other disqualifying health coverage, not be enrolled in Medicare, and not be claimed as someone else’s dependent.
| 2026 contribution limit, self-only | $4,400 |
| 2026 contribution limit, family | $8,750 |
| Extra if 55 or older | $1,000 |
| HDHP minimum deductible | $1,700 self-only, $3,400 family |
| HDHP out-of-pocket maximum | $8,500 self-only, $17,000 family |
New for 2026: under the 2025 tax law (the One Big Beautiful Bill Act), bronze and catastrophic plans available through an ACA Exchange count as HSA-eligible plans even if they do not meet the usual deductible rules. Some direct primary care memberships (up to $150 a month, or $300 for more than one person) no longer block HSA eligibility. Telehealth before the deductible is also allowed permanently.
The three tax breaks
- In: contributions are deductible. Through payroll they skip income tax and generally Social Security and Medicare tax too.
- Growth: interest, dividends and gains inside the HSA are not taxed.
- Out: withdrawals for qualified medical expenses are tax-free.
Withdrawals for anything else are taxed as income, plus a 20% additional tax if you are under 65. After 65 (or if disabled) the 20% goes away, so non-medical withdrawals are taxed like a traditional IRA.
Once you enroll in Medicare your contribution limit becomes zero, though you can keep using the money.
Investing inside the HSA
Many HSAs start as a cash account with a debit card. Many providers also offer an investment option, often after you keep a minimum in cash. If your provider charges high fees or has a short fund list, you can move the money to another HSA provider by trustee-to-trustee transfer.
A common setup: keep enough cash to cover your deductible, invest the rest in low-cost diversified funds. The mix follows the same logic as any account: money you might spend this year stays in cash, long-term money can take more risk.
The receipts strategy
You can reimburse yourself tax-free for qualified medical expenses you incurred after you opened the HSA. The IRS does not require you to withdraw in the same year. So some people pay medical bills from their checking account, keep the receipts, and let the HSA grow. Years later they can reimburse themselves for those old bills, tax-free.
Worked example
Priya, 35, has self-only HDHP coverage and contributes the 2026 maximum of $4,400 a year through payroll. She pays her small medical bills out of pocket and keeps the receipts.
| Yearly contribution | $4,400 |
| Assumed return | 6% a year (illustration only) |
| Years | 20 |
| Balance after 20 years | About $171,600 |
| Tax on growth if spent on medical care | $0 |
Future limits will change with inflation, so the real figure would differ. Where the HSA fits in your account order is covered in the investing guide.
