If you're enrolled in a high-deductible health plan (HDHP), you're likely eligible for one of the most valuable financial tools in health insurance: a Health Savings Account, or HSA. Used correctly, an HSA offers tax benefits that no other account can match—and the money never expires. Here's how to make the most of it.
The Triple Tax Advantage
The HSA is often called "triple tax-advantaged" because:
- Contributions are tax-deductible (or pre-tax if through payroll) — you reduce your taxable income by the amount you contribute.
- Growth is tax-free — interest and investment gains in the HSA are never taxed as long as they stay in the account.
- Withdrawals for qualified medical expenses are tax-free — you pay no tax when using the funds for healthcare.
In contrast, a Flexible Spending Account (FSA) only gets benefit #1 and has a "use it or lose it" rule. The HSA's triple benefit makes it superior for most people who are eligible for it.
2026 HSA Contribution Limits
| Coverage Type | 2026 Limit | Catch-Up (Age 55+) |
|---|---|---|
| Individual (self-only HDHP) | $4,300 | +$1,000 |
| Family (HDHP covering 2+ people) | $8,550 | +$1,000 |
Who Qualifies for an HSA?
To open and contribute to an HSA, you must:
- Be enrolled in an HSA-eligible HDHP (your plan documents will state this)
- Not be covered by any other non-HDHP health insurance
- Not be enrolled in Medicare
- Not be claimed as a dependent on someone else's tax return
How to Open an HSA
If your HDHP is through your employer, your employer may offer a companion HSA. If you're enrolled in a marketplace HDHP, you'll need to open an HSA on your own—through a bank, credit union, or HSA-specific provider. Many major banks (Fidelity, HSA Bank, HealthEquity) offer HSAs with investment options once your balance exceeds a threshold (often $1,000–$2,000).
Once your HSA balance is large enough, most providers let you invest it in mutual funds or index funds. If you can pay current medical expenses out of pocket and let your HSA grow invested, the compounding tax-free growth over decades can be substantial. Some people treat their HSA as a retirement healthcare fund.
What You Can Pay for With an HSA
HSA funds can be used for a wide range of qualified medical expenses, including:
- Doctor's office visits, hospital stays, surgery
- Prescription drugs and most OTC medications (since 2020)
- Dental and vision care (exams, glasses, contacts, braces)
- Mental health services
- Medical equipment (crutches, blood pressure monitors, etc.)
- COBRA and long-term care insurance premiums
- Medicare premiums (Part B, D, Medicare Advantage) after age 65
You generally cannot use HSA funds to pay ACA marketplace health insurance premiums—that's the one major exception. After age 65, you can withdraw HSA funds for any reason (you'll pay income tax but no penalty, similar to a traditional IRA).
The "Shoebox Strategy"
There's no rule requiring you to use HSA funds in the year you incur the expense. You can pay current medical expenses out of pocket, save your receipts, and reimburse yourself from the HSA years later—even in retirement. This allows your HSA to grow tax-free in the meantime. Keep meticulous records.
