A health savings account (HSA) is a tax-advantaged account designed to help you save for health care costs. Plus, when your HSA savings levels reach a certain threshold, you can invest the money, much like a 401(k) plan or other retirement account.

Key Points

  • An HSA offers triple tax benefits.
  • After age 65, an HSA can act as a “backup” IRA.
  • It’s possible to invest HSA funds and take advantage of compounding returns.

What are HSA triple tax savings?

You know what they say about death, taxes, and certainty. But what if taxes weren’t certain?

What if you could avoid them completely—on at least some of your money? A health savings account can help you shelter a chunk of your money from taxes. In fact, HSA proponents call it “triple tax savings.” Here’s how:

  • You contribute with pretax dollars, which reduces your taxable income for the current tax year.
  • Your money grows tax-free over time, with no taxes on interest, dividends, or capital gains.
  • Any money you withdraw—provided it’s used for qualified medical expenses—is also tax-free.

As long as you plan your spending so HSA funds are used only for qualified medical expenses, you don’t have to worry about paying taxes on that money. Plus, funds in your HSA roll over from year to year, so you’re not required to spend down your account. You can let the money grow indefinitely.

What are the HSA rules for eligibility?

You need to meet certain conditions to start a health savings account. Here are the HSA rules for eligibility:

  • You must have a high-deductible health plan (HDHP). Many plans indicate whether they are high-deductible and qualify as an HSA plan.
  • You have no other health coverage (with a few exceptions).
  • You aren’t enrolled in Medicare.
  • No one claims you as a dependent on their tax return.

As long as you meet these criteria, you can open and contribute to an HSA.

A note on HDHPs: High-deductible health plans typically have lower monthly premiums than those of comparable preferred-provider organizations (PPOs). But, as the name implies, you’ll have higher out-of-pocket expenses (up to the deductible) before the HDHP steps in to help cover expenses. With a little diligence, though, you can take the monthly premium savings and put it in your HSA.

What are the HSA contribution limits for 2024?

The HSA contribution limits depend on whether you’re an individual or a family. The IRS adjusts the contribution limit each year based on inflation. For 2024, the contribution limits are:

  • Individual with self-only coverage: $4,150
  • Individual with family coverage: $8,300

If you’re over 55 (and not covered by Medicare), you can make an extra $1,000 contribution. If you and your spouse have a HDHP family plan, you’re both over 55, and you don’t have Medicare, that makes a $2,000 total bonus contribution each year.

Note that you can make previous-year contributions up to the following year’s tax deadline. So, for 2023, you can contribute to your HSA until April 15, 2024. For the 2024 tax year, you can make contributions until April 15, 2025. Make sure to indicate whether the contribution is a previous-year or current-year contribution.

What are the HSA tax rules for withdrawals?

In general, as long as you withdraw the money from your HSA and use it for qualified medical expenses, you don’t pay taxes on it. There is no requirement to wait a certain period of time before making your first withdrawal (as there is with a tax-advantaged retirement account). Even if you’re no longer eligible to make contributions, you can still withdraw the money tax-free as long as it’s for qualified costs.

If you withdraw funds before age 65 and use them for nonqualified expenses, you’ll be subject to a 20% penalty.

Good to know

It’s possible to use your HSA as a “backup” retirement account. Once you reach age 65, you can withdraw money from your HSA and use it for nonmedical expenses without the 20% penalty. You just have to pay taxes on the money—as you would with a regular IRA. You can also use the HSA funds to cover health insurance premiums.

How can I use an HSA for long-term savings and retirement?

Because HSA tax savings offer a triple benefit, some people incorporate a health savings account into their long-term financial and retirement planning. Some potential strategies include:

  • Use only what you need immediately. Consider using HSA funds only for out-of-pocket health care costs that are immediate and necessary. The rest of your contributions can be invested, benefiting from compounding returns over time.
  • Save for future medical procedures. You can use your HSA to save up for future procedures and medical emergencies. In some cases, out-of-pocket costs can still be devastating. An HSA can serve as a health care emergency fund to help cover those costs without breaking your budget.
  • HSA as a health care account in retirement. By investing the bulk of your contributions, it’s possible to build a long-term portfolio that can be used in retirement. The HSA can then cover costs (including Medicare premiums) related to health care. Other retirement accounts, such as IRAs and 401(k)s, can be used for everyday expenses.
  • Reimburse all your health care costs at once. It’s possible to reimburse yourself later for past out-of-pocket qualified expenses. Some people use after-tax dollars today to pay medical costs, then save their receipts (digitally or physically) over time. Later, during retirement, they reimburse themselves from the HSA for all those costs at once, providing a chunk of tax-free capital during retirement.
  • Backup IRA. Finally, it’s possible to use an HSA as another tax-advantaged retirement account. If you wait until you’re 65 to access invested funds, you can treat unqualified expenses as if they’re distributions from an IRA. You’ll need to pay federal (and typically state) taxes, but you won’t get zinged by that 20% tax penalty.

The bottom line

A health savings account is one way to invest for your future with tax-advantaged funds. In fact, the HSA is one of the very few available ways to completely avoid taxes on a portion of your money—provided you withdraw funds only for qualified expenses.

If you want to invest part of your HSA, you’ll need to set up an account with a custodian and make sure that money is kept separate from the rest of your portfolio. But once you have a system in place, you can use an HSA to get the most out of your health care spending, with triple-tax savings to help power your investment strategy.
