Health care costs can be a significant financial burden, especially when faced with unexpected medical expenses. To help offset these costs, many people turn to Health Savings Accounts (HSAs). An HSA is a valuable financial tool designed to help individuals save money for medical expenses while enjoying a number of tax benefits. But what exactly is a Health Savings Account, and how does it work? In this article, we will explore the basics of HSAs, how they can be used, their benefits, and how to make the most of this account.
What is a Health Savings Account?
Definition of a Health Savings Account (HSA)
A Health Savings Account (HSA) is a tax-advantaged savings account that allows individuals to set aside money to pay for qualified medical expenses. The funds in an HSA are designed to be used for medical expenses not covered by insurance, such as deductibles, copayments, prescriptions, and certain treatments. Unlike other types of savings accounts, HSAs offer triple tax advantages: tax-deductible contributions, tax-free growth, and tax-free withdrawals for qualifying medical expenses.
How Does an HSA Work?
An HSA works by allowing you to contribute money into the account, which can then be used for medical expenses. The key to using an HSA is to pair it with a high-deductible health plan (HDHP). In order to open and contribute to an HSA, you must be enrolled in a qualifying HDHP. These plans have higher deductibles and lower premiums than traditional health insurance, which makes them an attractive option for individuals who want to save money on health care costs.
Once you have an HSA, you can contribute pre-tax income into the account up to an annual limit set by the IRS. You can use the funds in the account at any time to pay for qualified medical expenses without incurring taxes or penalties. The unused funds roll over year after year, and the account balance continues to grow, making HSAs a great long-term savings option.
Eligibility for a Health Savings Account
Who Can Open an HSA?
Not everyone can open an HSA. To be eligible, you must meet the following criteria:
- Enrollment in a High-Deductible Health Plan (HDHP): As mentioned, you must be enrolled in a qualified HDHP. These plans have a higher deductible compared to standard health insurance plans, but they usually offer lower monthly premiums. The IRS sets the annual deductible minimums and maximum out-of-pocket expense limits for HDHPs.
- No Other Health Coverage: You cannot be enrolled in any other health insurance plan that is not a high-deductible plan. This includes being covered under a spouse’s non-HDHP or having access to Medicare. You must also not be claimed as a dependent on someone else’s tax return.
- Not Enrolled in Medicare: Once you enroll in Medicare (usually at age 65), you can no longer contribute to your HSA. However, you can still use the funds already in your account for eligible medical expenses.
Contribution Limits
Each year, the IRS sets contribution limits for HSAs. For 2025, the contribution limits are as follows:
- Individual Coverage: Up to $3,850
- Family Coverage: Up to $7,750
Additionally, individuals aged 55 and older can make a “catch-up” contribution of an extra $1,000 annually, which means they can contribute a total of $4,850 for individual coverage or $8,750 for family coverage.
How to Use an HSA
Paying for Qualified Medical Expenses

The primary use of your HSA is to pay for qualified medical expenses. These are expenses that the IRS defines as necessary for medical care, including:
- Doctor’s visits
- Prescription medications
- Hospital stays
- Dental care (such as cleanings and fillings)
- Vision care (such as glasses and contact lenses)
- Chiropractic services
- Mental health services
- Certain medical equipment (such as crutches or blood sugar monitors)
The best part about an HSA is that withdrawals for qualified medical expenses are tax-free. This means you don’t have to pay any income taxes on the funds you take out for medical expenses, as long as they meet the IRS guidelines.
Paying for Non-Medical Expenses
If you use the funds in your HSA for non-medical expenses, the withdrawals will be subject to income tax. Additionally, if you are under age 65, you will incur a 20% penalty on the amount withdrawn for non-medical purposes. After age 65, however, you can use the funds for any purpose without the penalty (though you will still owe income tax if the funds are not used for qualified medical expenses).
Investing HSA Funds
Another attractive feature of HSAs is the ability to invest the funds in the account once your balance reaches a certain threshold. Many HSA providers offer investment options, including mutual funds and stocks, which can help your account grow over time. This can turn your HSA into a powerful long-term investment tool, especially if you are not using the funds for immediate medical expenses.
HSA Rollover
Unlike Flexible Spending Accounts (FSAs), HSAs allow you to carry over any unused funds year after year. This means that if you don’t use all the funds in your account in a given year, they will roll over and remain available for use in the future. This rollover feature makes HSAs especially beneficial for long-term savings and planning.
Benefits of a Health Savings Account
Triple Tax Advantage
One of the most significant benefits of an HSA is the triple tax advantage it offers:
- Tax-Deductible Contributions: The money you contribute to an HSA is tax-deductible, which reduces your taxable income for the year you contribute. This helps lower your overall tax bill.
- Tax-Free Growth: The funds in your HSA grow tax-free. Any interest, dividends, or investment gains made in the account are not subject to tax, which allows your savings to grow more quickly over time.
- Tax-Free Withdrawals: When you use the funds in your HSA for qualified medical expenses, you don’t have to pay any taxes on the withdrawal, making it an excellent way to save for health care costs in retirement.
Lower Health Care Costs
By using an HSA in conjunction with a high-deductible health plan, you can save money on monthly premiums, which can be a significant advantage if you are generally healthy and don’t anticipate large medical expenses. The HSA gives you a tax-efficient way to save for those unexpected costs without the burden of paying for more expensive traditional insurance plans.
Flexibility and Control
HSAs provide greater control over your health care spending. You can choose how much to contribute, how to invest the funds, and how to use the money for your medical expenses. Additionally, the ability to roll over unused funds from year to year gives you the flexibility to build a large account balance for future needs.
Medical Expenses in Retirement

One of the biggest benefits of an HSA is its potential to help cover medical expenses in retirement. Medical costs tend to rise as you age, and an HSA can serve as a tax-efficient way to save for these costs. After age 65, you can use the funds for any purpose without penalty (though you will owe income tax if it is not used for medical expenses), making it an effective retirement tool.

FAQs
Q. Can I have an HSA if I’m on Medicare?
No, you cannot contribute to an HSA once you are enrolled in Medicare. However, you can still use the funds in your HSA to pay for medical expenses.
Q. What is the deadline to contribute to an HSA?
You can contribute to your HSA until the tax filing deadline for the year. For most people, this means you have until April 15 of the following year to make contributions for the previous tax year.
Q. Can I use my HSA for over-the-counter medications?
Yes, you can use your HSA for over-the-counter medications, but only if they are prescribed by a doctor. The IRS now allows over-the-counter medications to be eligible for tax-free withdrawals as long as you have a prescription for them.
Q. Can I use my HSA to pay for health insurance premiums?
You can use your HSA to pay for health insurance premiums only in specific cases, such as paying for premiums while on COBRA, premiums for long-term care insurance, or premiums while receiving unemployment benefits. Regular health insurance premiums are not eligible for tax-free withdrawals.
Q. How is an HSA different from an FSA?
The main difference between an HSA and a Flexible Spending Account (FSA) is that HSAs allow funds to roll over year after year, while FSAs have a “use-it-or-lose-it” rule, where unused funds typically expire at the end of the year. Additionally, HSAs are only available to people with a high-deductible health plan, while FSAs can be used by anyone.
