A health savings account makes sense if you have a high-deductible health plan and expect to pay medical costs out of pocket in the next few years
An HSA is worth opening if three things are true: you are enrolled in a high-deductible health plan (HDHP), you have money to set aside without touching it, and you want to reduce what you pay in taxes on medical expenses. If you have a low-deductible plan through your employer or Medicare, an HSA is not available to you. If you rarely see a doctor and have no ongoing prescriptions, the tax savings may not outweigh the account fees.
The core trade-off is this: you contribute pre-tax money to an HSA, use it to pay medical bills, and never pay income tax on that money. But you can only open an HSA if your health plan has a deductible of at least $1,500 (for individual coverage) or $3,000 (for family coverage) in 2024, and you cannot be covered by any other health plan at the same time. If your employer offers a traditional plan with a low deductible, switching to an HDHP to get an HSA means accepting higher out-of-pocket costs when you need care.
Key Takeaways
- You can only open an HSA if you are enrolled in a high-deductible health plan and have no other health coverage, including Medicare or a spouse's low-deductible plan.
- An HSA saves money only if you have medical expenses to pay; the tax break applies only to money you actually spend on care.
- Money in an HSA rolls over year to year and can be invested, so it works best if you can afford to leave some untouched and let it grow.
- If your employer offers an HSA match or contribution, opening one is almost always worth doing, because that is assistance programs toward your medical costs.
- You should not open an HSA if you expect major medical expenses you cannot afford to pay out of pocket, because the deductible will be higher than a traditional plan.
When an HSA saves you real money
An HSA saves money in two ways: the contribution reduces your taxable income, and the withdrawals for medical care are tax-free. If you contribute $3,000 to an HSA and you are in the 22% federal tax bracket, you save $660 in federal income tax that year. If you then use that $3,000 to pay for a doctor visit, prescription, or dental work, you owe no income tax on it.
This matters most if you have predictable medical costs. Someone taking a daily prescription, seeing a therapist monthly, or managing a chronic condition will use HSA money every year and see the tax savings add up. Someone who goes to the doctor once every three years may pay more in account fees than they save in taxes.
The real advantage appears over time. Money you do not spend stays in the account, earns interest or investment returns, and remains yours forever. At 65, you can withdraw HSA money for any reason without penalty (though non-medical withdrawals are taxed as income). This makes an HSA function like a retirement account if you can afford to leave the money untouched.
The cost of switching to a high-deductible plan
To open an HSA, you must enroll in an HDHP. These plans have lower monthly premiums but higher deductibles. Before you get the tax benefit of an HSA, you have to pay the full deductible out of pocket. If you switch from a plan with a $500 deductible to an HDHP with a $2,000 deductible, you are accepting $1,500 more in out-of-pocket costs when you need care.
Calculate whether the premium savings plus the HSA tax break cover the higher deductible. If your employer pays part of the premium difference, that math gets easier. If you are buying your own plan, compare the total cost: monthly premium plus expected out-of-pocket spending. An HDHP makes sense only if the lower premium and HSA tax savings exceed what you expect to spend on medical care.
Do not switch to an HDHP if you have planned surgery, ongoing specialist care, or expensive prescriptions coming up. The higher deductible will cost you more than the HSA tax break saves.
Employer contributions and matching
Many employers contribute to their employees' HSAs or match contributions the way they match 401(k) money. If your employer puts $1,000 into your HSA, that is $1,000 you do not have to contribute yourself, and it is not taxed as income to you. This is one of the strongest reasons to open an HSA.
Ask your benefits administrator whether your employer contributes to HSAs, how much, and whether you have to contribute first to receive the match. Some employers contribute automatically; others only match if you contribute. If your employer matches, opening an HSA is almost always worth doing, even if you do not expect major medical expenses that year.
Who cannot open an HSA
You cannot open an HSA if you are enrolled in Medicare, covered by a spouse's health plan that is not an HDHP, or covered by a plan from a parent or other family member. You also cannot have a Health Flexible Spending Account (FSA) at the same time, though you can have a limited-purpose FSA that covers only dental and vision.
If you are self-employed and buy your own health plan, you can open an HSA as long as the plan meets the HDHP requirements. If you are unemployed and uninsured, you cannot open an HSA until you enroll in an HDHP.
Account fees and where to open one
HSAs are offered through banks, credit unions, and investment firms. Some charge monthly maintenance fees ($2 to $5), per-transaction fees, or investment fees if you invest the money. Others charge no fees at all. If you expect to use the account every month and keep a low balance, high fees will eat into your tax savings.
Compare accounts based on your expected usage. If you will spend the money quickly and not invest it, choose an account with low or no fees and easy access to debit cards or transfers. If you plan to invest the money and leave it untouched for years, look for an account with low investment fees and a wide range of investment options.
Your employer may offer an HSA through a specific provider as part of your benefits package. If so, check whether that provider charges fees and whether you can transfer the money to a different HSA provider later. You own the HSA, not your employer, so you can move the money if you find a better option.
HSA versus FSA: which one to choose
A Flexible Spending Account (FSA) is similar to an HSA but works differently. FSA money does not roll over—you lose what you do not spend by the end of the year (with a small carryover or grace period depending on your plan). FSAs do not require an HDHP, so you can have one with any health plan. You can have both an FSA and an HSA if your FSA is limited-purpose (covering only dental and vision).
Choose an FSA if you have predictable medical expenses you will definitely use each year and you want to set aside money without the commitment of an HSA. Choose an HSA if you want money to roll over, you are willing to switch to an HDHP, and you may not spend all the money every year. If your employer matches HSA contributions and does not match FSA contributions, the HSA is the better choice.
Frequently Asked Questions
Can I open an HSA if my employer does not offer one?
Yes. You can open an HSA through a bank, credit union, or investment firm as long as you are enrolled in an HDHP and have no other health coverage. You will not receive an employer contribution, but you can still contribute your own money and receive the tax benefit.
What happens to my HSA if I change jobs?
Your HSA stays with you. The money is yours, not your employer's. You can keep the account open, continue contributing if you are still enrolled in an HDHP, and take it with you to a new job. If your new employer offers an HSA through a different provider, you can transfer the balance or keep both accounts open.
Can I use HSA money to pay for my spouse's medical care?
Yes, as long as your spouse is claimed as a dependent on your tax return. You can also use HSA money to pay for any dependent's medical care. The money does not have to be used only for your own expenses.
What if I do not spend all my HSA money in a year?
The money rolls over to the next year. Unlike an FSA, there is no "use it or lose it" rule. You can let the balance grow and use it in future years, or invest it and let it earn returns. At 65, you can withdraw the money for any reason, though non-medical withdrawals are taxed as regular income.
Is an HSA worth it if I rarely go to the doctor?
It depends on account fees and the premium savings. If your HSA has no fees and your employer contributes money, it is worth opening even if you do not expect to use it. If you pay monthly fees and the HDHP premium is not significantly lower than a traditional plan, the HSA may not save you money.
