Health Savings Accounts
Who can open a health savings account, the tax benefits at every stage, the limits for the current year, what happens if you use the money for something other than medical costs, and why some people treat an HSA as a long-term investment account.
The short version
A health savings account (HSA) is for people covered by a high-deductible health plan and no other disqualifying coverage. Contributions are deductible or come out of pay before tax, the money grows without tax, and withdrawals for qualified medical expenses are tax-free. For 2026, you can contribute up to $4,400 with self-only coverage or $8,750 with family coverage, plus $1,000 from age 55. Unused money carries over every year. Withdrawals for anything else are taxed and, before age 65, owe an additional 20% tax. Since January 2026, more marketplace plans qualify, including bronze and catastrophic plans.
By the end of this lesson, you'll be able to
- Describe who is eligible to contribute to an HSA
- Explain the HSA's tax benefits and the cost of non-medical withdrawals
- Compare spending an HSA now with investing it for later
Why this matters
This optional lesson covers an account that's built for health costs but treated generously by the tax code. If your health plan qualifies, an HSA can lower your taxes on medical spending now, and it can also be invested and saved for health costs decades away.
Who can contribute
To contribute to a Health savings account (HSA). An account for medical costs, open to people covered by a qualifying high-deductible health plan, with tax benefits when money goes in, grows, and comes out for qualified expenses. Glossary, you generally must:1
- be covered by a High-deductible health plan (HDHP). A health plan whose deductible and out-of-pocket costs meet IRS limits. Being covered by one is the main requirement for contributing to an HSA. Glossary (HDHP),
- have no other health coverage, apart from types the rules allow, such as dental and vision,
- not be enrolled in Medicare, and
- not be someone who can be claimed as a dependent on another person's tax return.
For 2026, an HDHP must have a deductible of at least $1,700 for self-only coverage or $3,400 for family coverage, and out-of-pocket costs capped at no more than $8,500 or $17,000.2 A 2025 law widened the rules: since January 2026, bronze and catastrophic plans bought as individual coverage through a health insurance Exchange count as HDHPs.3 The same law also lets an HDHP cover telehealth before the deductible without disqualifying you.1
You open an HSA with a trustee, such as a bank or an insurance company. It doesn't have to be the same company as your health plan, and you don't need IRS permission.1
Tax benefits at every stage
- Going in. Your contributions are deductible even if you don't itemize, and contributions from your employer aren't counted as income.
- While invested. Interest and other earnings in the account aren't taxed.
- Coming out. Withdrawals used for qualified medical expenses are tax-free.1
For 2026, the limit is $4,400 with self-only coverage or $8,750 with family coverage,2 plus $1,000 if you're 55 or older. Contributions for a year can be made until the tax-filing deadline, usually April 15 of the next year.1
