The complete guide for 2026

What Is a Health Savings Account (HSA)?

A tax-advantaged savings account that lets you pay for medical expenses with pre-tax dollars - and invest the rest for retirement.

A Health Savings Account (HSA) is a tax-advantaged savings account available to individuals enrolled in a High Deductible Health Plan (HDHP). Contributions are tax-deductible, growth is tax-free, and withdrawals for qualified medical expenses are tax-free.

How HSAs Work

Five steps from enrollment to tax-free spending (or investing).

Enroll in an HDHP

A High Deductible Health Plan is required. These plans have lower premiums and higher deductibles than traditional health insurance.

Open an HSA

Open an account through your employer or independently with a provider like Fidelity, Lively, or HealthEquity.

Contribute pre-tax dollars (up to $4,400/$8,750 in 2026)

Contributions reduce your taxable income. If made through payroll, they also skip FICA taxes.

Use funds for qualified medical expenses - tax-free

Doctor visits, prescriptions, dental, vision, and hundreds more. No taxes on withdrawals for eligible expenses.

Or invest and let it grow - also tax-free

Once your balance crosses a threshold (usually $1,000–$2,000), you can invest in stocks, bonds, and index funds. All growth is tax-free.

Who Is Eligible for an HSA?

You must meet all four requirements to contribute to an HSA.

Enrolled in a High Deductible Health Plan (HDHP)
Minimum deductible of $1,700 (self-only) or $3,400 (family) in 2026.
Not enrolled in Medicare
Once you enroll in any part of Medicare, you can no longer contribute (but you can still spend existing funds).
Not claimed as a dependent on someone else's tax return
No other non-HDHP health coverage
Exceptions: dental, vision, and limited-purpose FSAs are allowed alongside an HSA.

How to Open an HSA

Three steps to get started.

Check if your health plan qualifies as an HDHP

Look at your plan details or ask HR. The deductible must be at least $1,700 (self) or $3,400 (family) for 2026.

Choose an HSA provider

Your employer may offer one, or you can open an account independently. Look for low fees and good investment options.

Start contributing

HSA vs HRA

HRAs are employer-funded and employer-owned. HSAs are yours to keep regardless of employment.

Frequently Asked Questions

What does HSA stand for?▼

HSA stands for Health Savings Account. It's a tax-advantaged savings account created by the Medicare Prescription Drug, Improvement, and Modernization Act of 2003.

Is an HSA a savings account or insurance?▼

An HSA is a savings account, not insurance. It works alongside your High Deductible Health Plan (HDHP) to help you save and pay for medical expenses with pre-tax dollars. Your HDHP is the insurance; the HSA is where you save money for expenses your insurance doesn't cover.

Do HSA funds expire?▼

No. Unlike a Flexible Spending Account (FSA), HSA funds roll over indefinitely. There is no "use it or lose it" rule. Money in your HSA is yours forever, even if you change jobs, switch health plans, or retire.

Can anyone open an HSA?▼

No. You must be enrolled in a qualifying High Deductible Health Plan (HDHP), cannot be enrolled in Medicare, cannot be claimed as a dependent on someone else's tax return, and cannot have other non-HDHP health coverage (with exceptions for dental, vision, and limited-purpose FSAs).

Is an HSA worth it?▼

For most people with an HDHP, yes. The triple tax advantage (tax-deductible contributions, tax-free growth, and tax-free withdrawals for medical expenses) makes it one of the most powerful savings vehicles in the U.S. tax code. The longer you let it grow, the more valuable it becomes.

What happens to my HSA when I turn 65?▼

At 65, your HSA becomes even more flexible. You can still withdraw funds tax-free for qualified medical expenses. For non-medical expenses, withdrawals are taxed as ordinary income (like a traditional IRA) but no longer incur the 20% penalty. Many people use their HSA as a supplemental retirement account.
