HSAs Explained: The Triple Tax Break Most People Underuse (2027 Limits)

A Health Savings Account (HSA) is one of the most tax-friendly accounts in the U.S. — better, in some ways, than a 401(k). Yet many people who qualify either don’t open one or treat it like a basic spending account. Here’s how to use it well.

The triple tax advantage

1. Money goes in tax-free. Payroll contributions skip income tax (and usually FICA); direct contributions are tax-deductible.
2. It grows tax-free. Interest and investment gains aren’t taxed.
3. It comes out tax-free for qualified medical expenses.

Unlike an FSA, the money is yours: it rolls over every year and stays with you if you change jobs or retire. After 65, you can withdraw for non-medical expenses too — you’ll just pay income tax, like a traditional IRA. Before 65, non-medical withdrawals are taxed plus a 20% penalty.

Who can contribute

You must be covered by an HSA-eligible 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.

What changed recently

The 2025 federal tax law (often called the One Big Beautiful Bill Act) expanded HSA access starting in 2026:

• Bronze and Catastrophic individual-market plans are now treated as HSA-compatible, even if they don’t meet the usual HDHP limits.
• Direct primary care memberships no longer disqualify you, as long as the fee is no more than $150/month for an individual or $300/month for a family — and you can pay those fees from your HSA.
• Telehealth covered before the deductible no longer affects eligibility; this rule is now permanent.

What you can pay for

Qualified medical expenses under IRS rules include deductibles, copays, prescriptions, dental and vision care, many over-the-counter medicines and menstrual products, and medical equipment. You can also use HSA money for COBRA premiums, health insurance while receiving unemployment, and Medicare premiums after 65. Browse our HSA & FSA shopping list for everyday ideas.

3 ways to get more from your HSA

1. Get the employer match. If your employer contributes, make sure you’re set up to receive it — it counts toward your annual limit.
2. Invest the balance you won’t need soon. Many HSAs keep money in cash by default. Once you have an emergency cushion, investing can let it grow for years.
3. Save receipts and reimburse yourself later. You can pay medical bills out of pocket now and reimburse yourself from the HSA years later, tax-free, as long as the expense happened after you opened the account and you kept records.

Is an HSA plan right for you?

HSA-eligible plans usually have lower premiums and higher deductibles. They work best if you’re relatively healthy, can cover the deductible in a bad year, and will actually put money into the account. If you expect heavy medical use, a lower-deductible plan may save more. Compare with our guides on how deductibles work and metal tiers.
