While there is more than one type of account that allows you to save for healthcare, the health savings account, or HSA, is the most advantageous for most who qualify.
Healthcare is expensive, and there's no reason to believe that will change anytime soon in the United States. In fact, U.S. healthcare spending grew to $4.9 trillion in 2023 (that's $14,570 per person), the most recent year for which we have complete data.
The good news is an HSA is one tax-advantaged way you may be able to prepare for healthcare costs and decrease the financial burden on you and your family.
In this article, we'll start with a rundown of how HSAs work. We'll also discuss how to qualify for one and how to open an HSA account for your own healthcare needs.
What is an HSA?
What is an HSA?
A health savings account is a specialized type of account designed to help people save money and pay for qualified healthcare expenses in a tax-advantaged way.
It's important to mention that an HSA is a different type of account from a flexible spending account (FSA). FSAs are designed primarily to budget for current-year healthcare expenses. On the other hand, HSAs are a more flexible type of account, but they have stricter requirements for opening one.

Often, employers will offer the ability to open and contribute to HSAs for employees enrolled in qualifying healthcare plans (more on that in a bit).
In this case, contributions work similarly to a 401(k): Your HSA contributions are deducted from your paycheck, and the money will be excluded from your taxable income.
If your employer doesn't offer an HSA directly, you may be able to open a health savings account on your own. To name just a couple of examples, Fidelity offers HSAs (and excellent educational resources and guidance), and an institution called HSA Bank specializes in opening these accounts.
Once you've opened an HSA, the next step is to make your contributions, which you can do in regular installments or in a lump sum.
The HSA contribution limits are adjusted annually to account for inflation, and it's worth noting that there have been legislative efforts to dramatically increase the amount of money that can be contributed to an HSA. But for 2025, the HSA contribution limits are as follows.
2025 HSA contribution limits
For 2025, participants with individual health coverage can contribute as much as $4,300 to an HSA, and the limit for family coverage is rising to $8,550. There is a $1,000 catch-up allowance for account owners 55 or older.
There are a couple of things to note. First, these limits include any contributions your employer makes on your behalf.
Second, HSA contributions can be made until the tax deadline for the contribution year. That means you can make 2025 contributions to an HSA until April 15, 2026.

The main qualification for opening an HSA is enrollment in a qualifying high-deductible health insurance plan, as defined by the U.S. government. The exact definition can change over time, but as of 2025, the HSA eligibility requirements for a high-deductible health plan are:
- An annual deductible of $1,650 or more for individual coverage or $3,300 or more for family coverage
- An out-of-pocket maximum no greater than $8,300 (individual coverage) or $16,600 (family coverage)
The HSA requirements also state that you cannot be enrolled in Medicare or an ineligible health plan, even if you are also concurrently enrolled in an HSA-eligible health plan.

How does an HSA work?
HSAs have some excellent features that make them a great financial tool for those qualified.
First, money in an HSA can be carried over from year to year, unlike an FSA, which is generally a use-it-or-lose-it type of arrangement. What's more, HSA money can be carried over and invested while in the account.
This works similarly to most 401(k) plans. HSAs typically offer a menu of investment funds or automated portfolio options to choose from.
Second, HSAs have a rare triple tax benefit.
- Money contributed to an HSA is tax-deductible in the year your contributions are made.
- While money is in an HSA, it can be invested on a tax-deferred basis. That means you won't have to pay taxes on any dividends or capital gains you receive in the account as long as the money is in it.
- Money withdrawn from an HSA to pay for qualifying healthcare expenses is 100% tax-free, no matter how much it grew while invested in the account.
This triple tax advantage is unique and can be very beneficial -- especially if you leave money in your HSA long enough to generate meaningful returns. No retirement accounts offer the ability to deduct contributions and take tax-free withdrawals of investment profits.

It's also important to note that once you turn 65, you can use the money in an HSA for any reason, not just healthcare. For this reason, an HSA can also be a valuable component of your retirement savings strategy.
To be sure, any non-healthcare withdrawals will be treated as taxable income, so it's still preferable to use the money for healthcare costs. But if you have more in your HSA at the time you retire than you'll need for healthcare, it's nice that it can essentially double as a retirement plan.
As an additional note, you don't have to use the money in your HSA to pay for healthcare expenses as they arise. For example, if you have to pay a $500 emergency room bill and have the cash to cover it, it can be a smart idea to leave the money in the HSA alone to grow and compound for the future.
Should I open an HSA?
Should I open an HSA?
The short answer is yes, if you can.
If you qualify to contribute to an HSA, there's little justification for not taking advantage of it. Opening an HSA is a relatively quick and easy process, even if you do it on your own. And as we've seen, these accounts have some benefits that even the best tax-advantaged retirement accounts cannot match.
