The IRS Just Announced Higher HSA Limits—But Only 10% of Accounts Are Set Up for the Most Valuable Tax Break

Health savings accounts (HSAs) are best known for making medical costs less painful, letting eligible savers set aside pre-tax money and use it tax-free for qualified expenses. But an HSA can be more than a healthcare spending account—it can become a long-term wealth-building tool when savers use its powerful “triple tax advantage.”

The third advantage is where the vast majority of accounts fall short. While most HSA owners make tax-free contributions and tax-free withdrawals, few take it to the next level of investing their HSA dollars so the money can also grow tax-free over time.

The IRS's newly announced 2027 contribution limits are a fresh reminder that eligible savers may be leaving one of an HSA's biggest benefits untouched.

An HSA can be more than a tax-friendly way to pay medical bills. If you can pay some expenses out of pocket and invest HSA funds instead, tax-free growth can turn the account into a long-term healthcare asset.

The IRS has announced the HSA contribution limits for 2027, and eligible savers will be able to put away slightly more than they can in 2026. To contribute to an HSA, you must be enrolled in an HSA-eligible high-deductible health plan.

For self-only coverage, the limit will rise to $4,500 in 2027, up from $4,400 in 2026. For family coverage, the limit will increase to $9,000, up from $8,750.1 The $1,000 catch-up contribution for people age 55 and older will remain unchanged.

The new limits are also a reminder that an HSA does not have to be used only for this year's medical bills. The real power move is maxing out your HSA contribution—or getting as close as you can afford—because unused money can stay in the account, rolling over and growing tax-free for decades.

Most HSA owners are already using at least part of the account's tax advantage. Contributions can reduce taxable income, and withdrawals are tax-free when used for qualified medical expenses.

But the third tax break comes from letting HSA money grow tax-free—and ideally invested instead of sitting in cash. That is where most accounts fall short: Just 10% of HSAs are investment accounts, according to Devenir's 2024 year-end HSA research report.2

That triple tax advantage can make an HSA even more tax-friendly than an IRA when the money is used for eligible healthcare costs. Traditional IRAs let savers contribute tax-free, while Roth IRAs allow you to withdraw tax-free (in retirement). An HSA offers both: tax-free contributions and tax-free withdrawals for qualified medical expenses—plus the benefit of tax-free investment growth in between.

That is why the investing piece matters. Unlike a flexible spending account, HSA money does not expire at the end of the year. Unused funds can stay in the account, be invested, and keep growing for future healthcare costs—even decades later in retirement.

If you invest HSA money instead of spending it right away, save receipts for major qualified medical expenses. You can reimburse yourself later from the HSA, but you'll need records showing the withdrawal was for an eligible healthcare cost.

Fortunately, you don't have to max out your HSA or pay every medical bill out of pocket to use the account more strategically. The goal is to build as much surplus as you can afford, then invest the portion you are unlikely to need soon so it has more time to grow.

One approach is to treat your HSA like a backup fund for bigger healthcare costs, not a checking account for every small bill. If you can cover copays, prescriptions, or routine expenses from your regular cash flow, and reserve HSA withdrawals for larger expenses you can't comfortably cover another way, your HSA balance can grow over time.

Another strategy is to level up gradually. Try increasing your HSA contribution each year, the same way many workers raise their 401(k) contribution rate over time or after a pay bump. Even if you never reach the annual maximum contribution, every extra dollar you contribute—and every dollar you're able to leave invested—can be worth more in the future than it is today.
