You need a high-deductible health plan first, then open an HSA through a bank or financial institution

A Health Savings Account (HSA) is not something you get from your employer or the government. You open one yourself at a bank, credit union, or investment firm — but only if you are enrolled in a high-deductible health plan (HDHP). The HDHP is the requirement. Without it, you cannot open an HSA, and if you lose the HDHP, you cannot contribute to an existing HSA anymore (though you can keep the account and spend what is already in it).

The process takes about 15 minutes online or in person. You will need your Social Security number, proof of HDHP coverage, and a small opening deposit (often $0 to $25, depending on the institution). Once the account is open, you can start contributing immediately if you are still in the HDHP.

Key Takeaways

  • You must be enrolled in an HDHP to open an HSA; without one, no financial institution will let you create the account.
  • You open an HSA directly with a bank, credit union, or brokerage, not through your employer or a government office.
  • The IRS sets annual contribution limits based on whether your HDHP covers only you or your family; for 2024, the limit is $4,150 for self-only coverage and $8,300 for family coverage.
  • You can contribute through payroll deduction (if your employer offers it), a direct transfer from your bank, or a check deposit to the HSA.
  • Once you open the account, you own it — if you change jobs or leave your HDHP, the money stays yours and you can take it with you.

Confirm your health plan meets the HDHP definition

Before you contact a bank, check your health plan documents or call your insurance company to confirm you have an HDHP. The IRS defines an HDHP by its deductible and out-of-pocket limits. For 2024, an HDHP for self-only coverage must have a deductible of at least $1,600 and an out-of-pocket maximum of no more than $3,200. For family coverage, the deductible must be at least $3,200 and the out-of-pocket maximum no more than $6,400. These numbers change each year.

Your insurance company will tell you whether your plan qualifies. If you are unsure, ask them directly: "Is this plan an HSA-may be able to access high-deductible health plan?" They will say yes or no. If it is not an HDHP, you cannot open an HSA until you switch to one — usually during open enrollment at your job or through the health insurance marketplace.

Choose where to open your HSA

You can open an HSA at most banks, credit unions, and investment firms. Common options include large banks (Chase, Bank of America, Wells Fargo), online banks (Lively, HealthEquity, Fidelity), and credit unions. Each institution sets its own fees, investment options, and minimum balance requirements. Some charge monthly maintenance fees ($2 to $5), some charge per transaction, and some charge nothing.

If your employer offers an HSA through payroll, that is often the easiest route — your employer may even contribute money to it, and the deduction happens automatically before taxes. But you are not required to use your employer's HSA provider. You can open one anywhere and still contribute through payroll if your employer allows it. Compare a few options by looking at their fee structure and whether they offer investment options (stocks and mutual funds) or just a savings account. If you plan to invest the money long-term, an institution that offers investment options may be worth the slightly higher fees.

Gather your documents and open the account

You will need your Social Security number, proof of HDHP coverage, and a valid ID. Proof of coverage can be your insurance card, a letter from your insurance company, or a screenshot of your plan details from your employer's benefits portal. Most institutions let you upload these documents online during the application.

The application itself asks for your name, address, date of birth, and Social Security number — the same information you would give to open any bank account. You will also declare that you are covered by an HDHP and that you are not covered by any other health plan that would disqualify you (such as Medicare or Medicaid, with some exceptions). Once you submit, the account usually opens within one to three business days. You will receive a debit card or checkbook to spend from the account, and instructions on how to set up contributions.

Set up contributions from your paycheck or bank account

Once the account is open, you can start putting money in. If your employer offers HSA payroll deduction, you can enroll through your benefits portal or HR department. The money comes out of your paycheck before taxes, which lowers your taxable income for the year. This is the most common method and usually the simplest.

If your employer does not offer payroll deduction, or if you are self-employed, you can transfer money from your bank account to your HSA. Most HSA providers let you set up automatic monthly transfers or make one-time transfers online. You can also mail a check to the HSA provider, though this is slower. The IRS sets an annual contribution limit — for 2024, it is $4,150 if only you are covered by the HDHP, or $8,300 if your HDHP covers your family. You can contribute up to that limit across all HSAs you own (you should not have more than one, but if you do, the total across all of them cannot exceed the limit).

Understand the contribution deadline and tax reporting

You can contribute to an HSA for a given year until the tax filing deadline the following year — usually April 15. For example, you can make contributions for 2024 until April 15, 2025. This gives you a window after the year ends to catch up on contributions if you did not max out during the year itself.

At the end of each year, the HSA provider sends you a Form 5498-SA, which reports your contributions to the IRS. You do not file this form with your tax return, but you keep it for your records. If you contributed through payroll, your employer already reduced your taxable income, so there is nothing extra to do on your tax return. If you contributed from your personal bank account, you can deduct those contributions on your tax return (Form 1040, Schedule 1) to get the tax benefit.

Know what happens if you lose HDHP coverage

If you leave your HDHP — because you change jobs, switch to a different health plan, or enroll in Medicare — you can no longer contribute to your HSA. However, the money already in the account is yours to keep. You can spend it on medical expenses tax-free for the rest of your life, even after you are no longer in an HDHP. You can also leave the money invested and let it grow, and withdraw it whenever you need it for medical costs.

If you withdraw HSA money for something other than a may have access to medical expense before age 65, you owe income tax on the withdrawal plus a 20% penalty. After age 65, you can withdraw money for any reason without the penalty (though you still owe income tax on non-medical withdrawals). This makes an HSA a powerful long-term savings tool if you can afford to leave the money in it and pay medical expenses out of pocket.

Frequently Asked Questions

Can I open an HSA if I am self-employed?

Yes. You need an HDHP, which you can buy through the health insurance marketplace or a private insurer. Once you have the HDHP, you can open an HSA at any bank or financial institution. You contribute from your personal bank account rather than through payroll, and you deduct the contributions on your tax return.

What if my employer already opened an HSA for me?

You can use it, or you can open a separate one elsewhere. If your employer contributes money to their HSA, you may want to keep that one to capture their contribution. But you can also roll the money over to a different HSA provider if you find better fees or investment options. The money is yours either way.

Do I have to spend the money in my HSA every year?

No. Unlike a flexible spending account (FSA), an HSA does not have a "use it or lose it" rule. Money you do not spend rolls over to the next year and the year after that. You can let it accumulate and invest it for decades if you want.

Can I use my HSA debit card to buy anything?

Only may have access to medical expenses. These include doctor visits, prescriptions, dental work, vision care, and medical equipment. The debit card is programmed to block purchases at non-medical merchants, though some transactions (like a pharmacy that also sells groceries) may require you to prove the purchase was medical.

What if I contribute too much to my HSA?

If you exceed the annual limit, you have until the tax filing deadline to withdraw the excess and any earnings on it. If you do not withdraw the excess, you owe income tax on it plus a 6% penalty. This is rare if you are contributing through payroll, because your employer usually stops deductions once you hit the limit.
