Health Savings Account (HSA): What It Is and How It Works

If you have a high‑deductible health plan (HDHP), you may be eligible to open a Health Savings Account (HSA). An HSA is a tax‑advantaged account designed to help you save and pay for qualified medical expenses. Unlike flexible spending accounts (FSAs), the money in an HSA does not have to be used by the end of the year—it rolls over year after year and can even be invested.

This guide explains the 2026 contribution limits, eligibility rules, the triple tax advantage, investment options, withdrawal rules, and how to choose an HSA provider.

1. 2026 HSA Contribution Limits

The IRS sets annual contribution limits for HSAs, which are adjusted for inflation each year. For 2026, the limits are:

The family limit is a combined cap for both spouses, even if each has their own HSA. Individuals age 55 or older can contribute an extra $1,000 as a catch‑up contribution. Contributions can be made by the account holder, their employer, or both, up to the annual limit.

2. Eligibility: Do You Qualify for an HSA?

To open and contribute to an HSA, you must meet the following requirements:

• Be covered by an HSA‑qualified high‑deductible health plan (HDHP)
• Have no other disqualifying health coverage (e.g., a general purpose FSA or Medicare)
• Cannot be claimed as a dependent on someone else‘s tax return

For 2026, an HDHP must meet the following minimum deductibles and maximum out‑of‑pocket limits:

If a family HDHP has an embedded individual deductible, that individual deductible cannot be lower than the family minimum deductible ($3,400 in 2026). Monthly premiums do not count toward the out‑of‑pocket maximum. Once you enroll in Medicare, you can no longer contribute to an HSA, although you can still use existing funds for qualified medical expenses.

3. The Triple Tax Advantage

HSAs offer a combination of tax benefits that no other account type provides.

When used for qualified medical expenses, HSAs are more tax‑efficient than traditional IRAs, Roth IRAs, and 401(k) plans. The longer funds remain invested, the greater the benefit from tax‑free compounding. For example, an investor who contributes 6,000toanHSAandearnsa56,000toanHSAandearnsa510,000, all tax‑free if used for qualified medical costs.

4. Qualified Medical Expenses

HSA funds can be used tax‑free for a wide range of medical, dental, and vision expenses. Common examples include:

• Doctor visit copays, deductibles, and coinsurance
• Prescription and over‑the‑counter medications
• Dental care (cleanings, braces, fillings)
• Vision care (eye exams, glasses, contact lenses, LASIK)
• Chiropractic care, acupuncture, and physical therapy
• Mental health counseling and psychiatric care
• Long‑term care services and insurance premiums
• Hearing aid and batteries
• Ambulance services

The official list of qualified expenses is published annually by the IRS in Publication 502. Expenses that are merely beneficial for general health (such as vitamins or gym memberships) generally do not qualify unless prescribed by a physician.

5. HSA Withdrawal Rules

Withdrawals from an HSA are treated differently depending on whether the money is used for qualified medical expenses.

There is no time limit on reimbursing yourself for past medical expenses, as long as the expense was incurred after the HSA was established. This makes it possible to pay for current healthcare costs out of pocket, let your HSA funds grow, and reimburse yourself years later—all tax‑free.

6. Investment Options for HSAs

Many HSA providers allow you to invest your balance in financial markets once you meet a minimum cash threshold (often 1,000to1,000to2,000). Investment options commonly include:

• Mutual funds (target‑date funds, index funds, actively managed funds)
• Exchange‑traded funds (ETFs)
• Stocks and bonds (through self‑directed brokerage accounts)
• U.S. Treasuries and FDIC‑insured CDs

Some providers offer self‑directed brokerage options through partners like Charles Schwab, giving you access to thousands of investment choices. Optum Financial, for example, offers a curated selection of over 30 mutual funds. Fidelity provides broad investing options with waived investment minimums and no monthly fees.

Because HSA growth is tax‑free, these accounts are well suited for long‑term investing. However, investment risk should be considered based on your expected time horizon for using the funds.

7. Major HSA Providers Compared

Choosing the right HSA provider can affect your costs and investment options. Below are three providers commonly compared in 2026.

If you have an HSA through your employer, your choice of provider may be limited. However, you are generally free to open your own HSA at any provider, even if you also have one through work.

8. Frequently Asked Questions (FAQ)

Q1: Is there an income limit for contributing to an HSA?

A: No. Unlike Roth IRAs, HSAs have no income‑based phase‑outs. Anyone enrolled in an HSA‑qualified HDHP can contribute up to the annual limit, regardless of how much they earn.

Q2: Can I use my HSA to pay for my spouse or dependents?

A: Yes. HSA funds can be used tax‑free for qualified medical expenses of the account holder, their spouse, and any dependent claimed on their tax return, even if the spouse or dependent is not covered by the HDHP.

Q3: What happens to my HSA if I change jobs or retire?

A: You keep your HSA. The account is owned by you, not your employer. You can continue to use the funds for qualified medical expenses, and you can roll the balance into a new HSA if desired.

Q4: Can I use my HSA to pay for Medicare premiums?

A: Yes. After age 65, HSA funds can be used tax‑free to pay for Medicare Part B, Part D, and Medicare Advantage premiums (but not Medigap premiums). Long‑term care insurance premiums are also eligible, subject to age‑based limits.

Q5: Is there a deadline for making HSA contributions for 2026?

A: The deadline to make HSA contributions for the 2026 tax year is typically April 15, 2027, when you file your federal tax return. Contributions made by that date can still be counted as prior‑year contributions.
