The three tax breaks that make HSAs different

A Health Savings Account gets three separate tax advantages that regular savings accounts do not. Money you put in is not taxed as income. The money sitting in the account earns interest or investment returns without being taxed. And when you withdraw it to pay for may have access to medical expenses, that withdrawal is not taxed either. No other savings vehicle gives you all three at once.

This is why HSAs are sometimes called "triple tax-advantaged." But the tax break only applies if you follow the rules. If you withdraw money for something that is not a may have access to medical expense, you pay income tax on that withdrawal plus a 20% penalty — unless you are 65 or older, in which case you pay the income tax but the penalty goes away.

The tax advantage exists because HSAs are meant to work with high-deductible health plans. The government created them to let people save for medical costs while paying less in taxes. The tradeoff is that you can only use the money for specific health-related expenses, and you have to prove you have a may have access to health plan to open one in the first place.

Key Takeaways

  • Contributions to an HSA are deducted from your taxable income, lowering the amount of federal income tax you owe that year.
  • Money inside the HSA grows without being taxed each year, whether it sits in cash or is invested in mutual funds or other options.
  • Withdrawals for may have access to medical expenses — copays, deductibles, prescriptions, dental work, vision care, and many others — are not taxed.
  • Withdrawals for non-medical expenses are taxed as income plus a 20% penalty before age 65, making HSAs expensive to raid for other reasons.
  • You must be enrolled in a high-deductible health plan to open or contribute to an HSA; the tax benefit disappears if you lose that coverage.

How the contribution tax break works

When you contribute money to an HSA, that amount reduces your taxable income for the year. If you earn $50,000 and put $3,000 into an HSA, the IRS treats your taxable income as $47,000. You pay federal income tax only on the $47,000.

This works the same way whether you contribute through payroll deduction (where your employer takes the money before taxes are calculated) or whether you contribute on your own and deduct it when you file your tax return. The result is the same: lower taxable income, lower tax bill.

The contribution limits change each year. For 2024, you can contribute up to $4,150 if you have individual coverage, or $8,300 if you have family coverage. If you are 55 or older, you can add an extra $1,000 per year. These limits are set by the IRS and announced in advance, so you can plan around them.

How the growth tax break works

Money inside an HSA can sit in a cash account earning interest, or you can invest it in mutual funds, stocks, or bonds — depending on what your HSA provider offers. Whatever earnings the money makes are not taxed each year the way they would be in a regular brokerage account.

If you have $10,000 in your HSA and it earns $500 in interest or investment gains over a year, you do not report that $500 as income on your tax return. In a regular savings account or investment account, you would owe tax on that $500. In an HSA, it stays tax-free as long as it remains in the account.

This advantage compounds over time. The longer money sits in an HSA untouched, the more it grows without being eaten by annual taxes. Some people treat HSAs as retirement savings vehicles for exactly this reason — they contribute the maximum each year, invest conservatively, and let the balance grow for decades.

How the withdrawal tax break works

When you withdraw money from an HSA to pay for a may have access to medical expense, that withdrawal is not taxed. may have access to expenses include copays, coinsurance, deductibles, prescription medications, dental work, vision care, hearing aids, mental health treatment, and many others. The IRS publishes a full list, but the basic rule is: if it is a medical or dental service or product that your health insurance would normally cover, it counts.

You do not need to submit receipts to your HSA provider when you withdraw money, but you should keep them. If the IRS ever audits your HSA, you need to prove that the money went to may have access to expenses. If you cannot prove it, the withdrawal is treated as taxable income plus the 20% penalty.

One detail that surprises people: you can withdraw money for a medical expense that happened years ago, as long as you have the receipt. If you paid $2,000 out of pocket for dental work in 2020 and did not reimburse yourself from your HSA at the time, you can withdraw $2,000 from your HSA in 2024 and it will not be taxed. This lets you keep money in the HSA invested longer while still getting the tax break when you need it.

What happens if you withdraw money for non-medical reasons

If you withdraw money from an HSA for something that is not a may have access to medical expense — a vacation, a car payment, groceries — you owe income tax on that withdrawal. You also owe a 20% penalty on top of the income tax. So if you withdraw $5,000 for a non-medical reason and you are in the 22% federal tax bracket, you would owe roughly $1,100 in taxes and penalties.

The penalty goes away once you turn 65. After that, you can withdraw money for any reason and only pay income tax on non-medical withdrawals — the same as you would with a traditional IRA. This is why some people view HSAs as retirement accounts: the money is triple-tax-advantaged while you are working, and after 65 it becomes a regular tax-deferred account.

Before age 65, the 20% penalty is steep enough that most people do not raid their HSA for non-medical expenses unless they are in a real bind. The tax advantage only exists if you actually use the money for health care.

The requirement: you must have a high-deductible health plan

You can only contribute to an HSA if you are enrolled in a high-deductible health plan (HDHP). The IRS sets the minimum deductible each year. For 2024, an HDHP must have a deductible of at least $1,600 for individual coverage or $3,200 for family coverage. Your plan also cannot have certain preventive care cost-sharing — meaning things like vaccines and screenings must be covered before you meet the deductible.

If you lose your HDHP coverage — because you switch to a different health plan, lose your job, or your employer changes plans — you can no longer contribute to an HSA. Money already in the account stays there and keeps growing tax-free, and you can still withdraw it for medical expenses without penalty. But you cannot add new money.

This is a real constraint for people who change jobs or whose employer switches health plans. You need to know whether your new plan qualifies as an HDHP before you assume you can keep contributing.

State taxes and the HSA tax advantage

The federal tax break is clear: contributions reduce your federal taxable income, growth is not taxed, and may have access to withdrawals are not taxed. State taxes are murkier and vary by state.

Most states follow federal rules and do not tax HSA contributions, growth, or may have access to withdrawals. But a few states — including California, New Jersey, and Tennessee — tax HSA contributions as income even though the federal government does not. If you live in one of these states, you get the federal tax break but not the state tax break on the money going in.

Before opening an HSA, check your state's rules. Your HSA provider or your tax preparer can tell you whether your state taxes contributions.

Frequently Asked Questions

Can I use HSA money to pay my health insurance premiums?

Not usually. You cannot use HSA money to pay premiums for your regular health insurance, dental insurance, or vision insurance. You can use it to pay premiums for long-term care insurance or for health insurance while you are receiving unemployment benefits, but those are narrow exceptions. The rule is: HSA money pays for medical expenses, not insurance itself.

What if I do not spend all my HSA money in a year?

The money rolls over. Unlike a flexible spending account (FSA), there is no "use it or lose it" rule with an HSA. Money you do not spend stays in the account and keeps growing tax-free indefinitely. This is one reason HSAs are valuable — you can accumulate a large balance over time.

Do I have to report my HSA on my tax return?

If you contribute through payroll deduction, your employer reports it and it is already deducted from your taxable income. If you contribute on your own, you deduct it on your tax return using Form 8889. Either way, the contribution shows up on your return, but the tax benefit is already built in.

Can I withdraw money for my spouse's medical expenses?

Yes. If you have family coverage and your spouse is on the plan, you can withdraw HSA money for your spouse's may have access to medical expenses. You can also withdraw for your children and dependents. The money just has to go toward someone's may have access to medical costs.

What counts as a may have access to medical expense?

The IRS list is long, but the basic rule is: if it is a medical or dental service or product that treats or prevents illness, it counts. Copays, deductibles, prescriptions, dental work, vision care, mental health treatment, and medical equipment all may have access to. Cosmetic procedures, vitamins, and gym memberships do not. The IRS publishes a full list on its website.
