A health care savings account is a tax-advantaged way to set aside money specifically for medical expenses

A Health Savings Account (HSA) is a savings account tied to a high-deductible health insurance plan. The money you put in reduces your taxable income, grows without being taxed, and comes out tax-free when you use it for medical bills. Unlike a regular savings account, the tax benefits only explore if you use the money for may have access to health care costs — things like doctor visits, prescriptions, dental work, and vision care.

The main appeal is the triple tax advantage: your deposits aren't taxed, the money inside grows without being taxed, and withdrawals for medical expenses aren't taxed. This makes an HSA more powerful than a regular savings account for health care costs, but it comes with rules about what you can spend it on and who can open one.

Key Takeaways

  • You can only open an HSA if you are enrolled in a high-deductible health insurance plan, which means your deductible is at least $1,550 for individual coverage or $3,100 for family coverage in 2024.
  • Money you contribute to an HSA reduces your taxable income for the year, and you can contribute up to $4,150 for individual coverage or $8,300 for family coverage in 2024.
  • You can use HSA money for may have access to medical expenses like doctor visits, prescriptions, dental care, and vision care without paying taxes on the withdrawal.
  • After age 65, you can withdraw money for any reason without penalty, though non-medical withdrawals are taxed as income.
  • Unlike a Flexible Spending Account (FSA), unused HSA money rolls over to the next year — you do not lose it.

Who can open an HSA and what the insurance requirement means

You must be enrolled in a high-deductible health plan (HDHP) to open an HSA. The IRS sets the minimum deductible each year — in 2024, that is $1,550 for individual coverage or $3,100 for family coverage. Your employer may offer an HDHP as one of their health plan choices, or you can buy one on the individual market through your state's health insurance marketplace or directly from an insurer.

You cannot have other health coverage at the same time, with limited exceptions. If you have Medicare, Medicaid, or coverage through a spouse's plan that is not an HDHP, you are not may be able to access. You also cannot be claimed as a dependent on someone else's tax return. Once you enroll in an HDHP, you can open an HSA through your employer (if they offer one), a bank, a credit union, or an investment company.

How much you can contribute and when

The IRS sets annual contribution limits. 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 (called a catch-up contribution). These limits change each year, so check the IRS website or your HSA provider's materials before you contribute.

You can contribute money yourself, or your employer can contribute on your behalf — or both. If your employer contributes, that amount counts toward your limit. You can contribute at any time during the year, but contributions for a specific tax year must be made by the tax filing important date (usually April 15 of the following year). Many people set up automatic monthly contributions through their employer's payroll, which also reduces their taxable income right away.

What you can spend HSA money on

may have access to medical expenses are the key to using your HSA without taxes. These include doctor visits, hospital stays, prescription medications, dental care, vision care (including glasses and contacts), hearing aids, and mental health treatment. You can also use HSA money for over-the-counter items like pain relievers and allergy medicine, but only if you have a prescription or a doctor's note saying you need them.

Some costs that sound medical are not covered. Cosmetic procedures, gym memberships, and vitamins (unless prescribed for a specific condition) do not count. If you are unsure whether a cost qualifies, ask your HSA provider or check IRS Publication 502, which lists all may have access to expenses. Keeping receipts and records is important — if you withdraw money for a non-may have access to expense, you owe income tax on that amount plus a 20% penalty.

How HSA money grows and what happens to unused funds

Unlike a Flexible Spending Account (FSA), which requires you to use the money or lose it each year, an HSA rolls over unused money to the next year indefinitely. This means you can let your HSA grow over time if you do not spend all of it. Many HSA providers let you invest the money in mutual funds or other investments, similar to a retirement account, so it can earn returns beyond just sitting in a savings account.

The longer you keep money in an HSA without touching it, the more it can grow. Some people use an HSA as a retirement savings tool — they pay for medical expenses out of pocket and let the HSA balance accumulate. After age 65, you can withdraw money for any reason without the 20% penalty, though non-medical withdrawals are taxed as regular income.

How an HSA differs from a Flexible Spending Account

Both HSAs and FSAs let you set aside pre-tax money for medical expenses, but they work differently. An FSA requires you to spend the money within the plan year or lose it (though some plans allow a small carryover or grace period). An HSA has no "use it or lose it" rule — your money stays in the account year after year. This makes an HSA better if you want to save for future medical costs.

An FSA does not require you to be on a high-deductible health plan, so it is available to more people. However, an HSA offers the triple tax advantage and the ability to invest the money, making it more powerful for long-term savings. If your employer offers both, compare the contribution limits, investment options, and fees to decide which works better for your situation.

What happens to your HSA if you change jobs or leave your employer

Your HSA belongs to you, not your employer. If you leave your job, the account stays open and the money remains yours. You can keep using it for medical expenses, and it continues to grow tax-free. You do not have to close it or transfer it anywhere unless you want to — many people keep their HSA with the same provider even after leaving the employer that helped them open it.

If you want to move your HSA to a different provider (for better investment options or lower fees, for example), you can do a trustee-to-trustee transfer, which does not count as a withdrawal and has no tax consequences. You can also roll over funds from one HSA to another once per year. If you lose your HDHP coverage — for example, by switching to a traditional health plan — you can no longer contribute to the HSA, but you can still withdraw money for medical expenses without penalty.

Frequently Asked Questions

Can I use my HSA for my spouse's or children's medical expenses?

Yes. You can use your HSA to pay for may have access to medical expenses for your spouse and any dependent children, even if they are not on your health insurance plan. You do not need to be on a family plan — individual coverage qualifies as long as you meet the other HSA rules.

What happens if I withdraw money for something that is not a medical expense?

You owe income tax on that amount, plus a 20% penalty. For example, if you withdraw $500 for a non-may have access to expense, you pay income tax on the $500 plus a $100 penalty. After age 65, the penalty goes away, but you still owe income tax on non-medical withdrawals.

Can I have both an HSA and an FSA at the same time?

Generally no. If you have an HSA, you cannot also have a traditional FSA. However, some employers offer a limited-purpose FSA that covers only dental and vision expenses, which you can use alongside an HSA. Check with your employer's benefits office about what combinations they allow.

Do I have to use my HSA money by a certain date each year?

No. Unlike an FSA, there is no important date to spend HSA money. You can let it accumulate for years and use it whenever you have a may have access to medical expense. This is one of the main advantages of an HSA over other health savings options.

What if I do not have any medical expenses — can I just leave the money in my HSA?

Yes. You can leave money in your HSA indefinitely without spending it. If you invest it, it can grow over time. Many people use their HSA as a long-term savings tool for health care costs in retirement, treating it similarly to a retirement account.
