What a Health Savings Account Plan Is

A health savings account plan is a type of health insurance paired with a savings account where you set aside pre-tax money to pay for medical costs. The insurance part has a higher deductible than traditional plans—meaning you pay more out of pocket before insurance kicks in. The savings account part lets you accumulate money tax-free, use it for may have access to medical expenses whenever you need to, and keep any unused balance year to year.

The account belongs to you, not your employer or insurance company. Money you don't spend stays in the account and grows. If you leave your job, the account goes with you. This differs from a flexible spending account (FSA), where unused money typically disappears at the end of the year.

Key Takeaways

  • An HSA plan combines a high-deductible health insurance policy with a tax-advantaged savings account for medical expenses.
  • You contribute pre-tax dollars to the account, meaning the money reduces your taxable income for the year.
  • You can use HSA funds to pay for deductibles, copays, prescriptions, dental work, vision care, and many other medical costs.
  • Unused money stays in your account and can be carried forward indefinitely, unlike FSA funds that expire each year.
  • After age 65, you can withdraw HSA money for any reason without penalty, though non-medical withdrawals are taxed as income.

How Money Flows Into and Out of Your HSA

You fund an HSA through payroll deductions if your employer offers one, or you can open an account independently and contribute on your own. The money you put in is not taxed as income—it reduces your taxable wages for that year. If you contribute $3,000 to an HSA and earn $50,000, you only pay income tax on $47,000.

You withdraw money from the account to pay for medical expenses. Most HSAs come with a debit card or checkbook so you can pay providers directly. You can also pay out of pocket and then reimburse yourself from the account later—even years later, as long as you keep receipts proving the expense was may have access to.

The account earns interest or investment returns depending on how much money is in it and which financial institution holds it. Some HSAs let you invest the balance in mutual funds or stocks once you reach a certain threshold, usually $1,000 or $2,000. Others keep the money in a savings account earning minimal interest.

What Expenses You Can Pay With HSA Money

may have access to medical expenses include deductibles, copays, and coinsurance for your health insurance. They also cover prescription medications, dental work (fillings, root canals, orthodontia), vision care (glasses, contacts, exams), hearing aids, and mental health treatment. Physical therapy, chiropractic care, and acupuncture count if a doctor prescribes them.

Over-the-counter medications like pain relievers and allergy medicine are covered only if you have a prescription from a doctor. Vitamins and supplements are generally not covered unless prescribed for a specific medical condition. Cosmetic procedures like teeth whitening or Botox are not covered, but reconstructive surgery after an injury or illness is.

You cannot use HSA funds to pay insurance premiums while you are working, with one exception: if you are receiving unemployment benefits, you can use HSA money to pay for health insurance premiums. After you turn 65 and enroll in Medicare, you can use HSA funds to pay Medicare premiums and for long-term care insurance.

Contribution Limits and How They Change Each Year

The IRS sets annual contribution limits that vary based on whether your insurance covers just you or your family. For 2024, the limit is $4,150 for individual coverage and $8,300 for family coverage. These limits change yearly and are announced in the fall for the following year. If you are 55 or older, you can contribute an additional $1,000 per year as a catch-up contribution.

Your employer may contribute to your HSA as well. Employer contributions count toward the annual limit, so if your employer puts in $2,000 and you put in $2,000, you have reached the $4,150 individual limit. You cannot exceed the limit even if you have multiple jobs or multiple HSA accounts.

If you contribute more than the limit, you owe income tax on the overage plus a 6 percent excise tax. The IRS will notify you if this happens, usually when you file your tax return. You can withdraw the excess and any earnings on it before the tax filing deadline to avoid the penalty.

What Happens to Your HSA When You Change Jobs or Retire

Your HSA stays with you when you leave your job. The account does not close, and the money does not disappear. You keep the debit card or checkbook and can continue using the funds for medical expenses. If your new employer offers an HSA, you can keep your old account open or roll the balance into the new one.

If your new job does not offer an HSA, you can still use the money in your existing account for may have access to medical expenses. You simply cannot make new contributions unless you open an individual HSA and have a may have access to high-deductible health plan. Once you enroll in Medicare at 65, you can no longer contribute to an HSA, but you can continue withdrawing for medical expenses.

If you die, your beneficiary inherits the HSA. If your spouse is the beneficiary, they can treat it as their own account and continue using it. If a non-spouse inherits it, they owe income tax on the full balance but can use the money for any purpose without penalty.

The Tax Advantage and Why It Matters

An HSA gives you a triple tax benefit: contributions are not taxed, growth is not taxed, and withdrawals for medical expenses are not taxed. This is different from a regular savings account, where you pay tax on interest earned, or a taxable investment account, where you pay tax on gains.

The tax savings depend on your income and tax bracket. If you are in the 24 percent federal tax bracket and contribute $3,000 to an HSA, you save $720 in federal taxes that year. State taxes vary, but many states also exempt HSA contributions from state income tax, adding another 5 to 10 percent in savings depending on where you live.

Over time, this compounds. If you contribute $3,000 per year for 20 years and earn 5 percent annual returns, your account grows to over $100,000. You never pay tax on that growth as long as you use the money for medical expenses. This makes an HSA a powerful tool for saving for healthcare costs in retirement.

How an HSA Plan Differs From Other Health Coverage

A traditional health insurance plan has a lower deductible but higher monthly premiums. You pay less out of pocket before insurance starts covering costs. An HSA plan flips this: you pay a lower monthly premium but a higher deductible. You are betting that you will not need much medical care, so the lower premium savings outweigh the higher deductible.

An FSA (flexible spending account) is similar to an HSA in that you set aside pre-tax money for medical expenses. The key difference is that FSA money expires at the end of the year—you lose whatever you do not spend. Some employers offer a grace period of up to 2.5 months into the next year, or let you carry over up to $640, but the money does not roll forward indefinitely like HSA funds do.

A Health Reimbursement Arrangement (HRA) is funded entirely by your employer, not by you. Your employer decides how much to put in and what expenses are covered. When you leave the job, you typically lose access to the remaining balance. An HSA is yours to keep and control.

Frequently Asked Questions

Can I use HSA money to pay for my spouse's medical expenses?

Yes. HSA funds can pay for medical expenses of you, your spouse, and any dependent you claim on your tax return, regardless of whether they are covered under your health insurance plan. You do not need to be on the same insurance policy.

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

You owe income tax on the withdrawal plus a 20 percent penalty. For example, if you withdraw $500 for a non-medical expense and are in the 22 percent tax bracket, you owe $110 in taxes plus $100 in penalty. After age 65, the penalty goes away, but you still owe income tax on non-medical withdrawals.

Can I open an HSA if my employer does not offer one?

Yes. You can open an individual HSA through a bank, credit union, or investment company as long as you are enrolled in a high-deductible health plan. The plan can come from the individual market, a spouse's employer, or a professional association. You cannot have an HSA if you are covered by any non-high-deductible health plan, including Medicare or Medicaid.

Do I have to spend all my HSA money before the end of the year?

No. Unlike an FSA, there is no "use it or lose it" rule for HSAs. Money rolls forward indefinitely. You can accumulate years of contributions and use them whenever you need to pay for medical expenses, even decades later.

Can I invest my HSA balance?

Many HSA providers allow you to invest the balance in mutual funds, stocks, or bonds once you reach a minimum threshold, often $1,000 to $2,500. Some providers do not offer investment options and keep the money in a savings account. Check with your HSA provider about what options are available.
