How to open an HSA

You open an HSA through a bank, credit union, or insurance company that offers HSA accounts — not through your employer or the government. Your employer may offer one through payroll, which makes contributions easier, but you can also open one independently at any financial institution that administers HSAs. The process takes about 15 minutes online or over the phone, and you'll need proof that you're covered by a high-deductible health plan (HDHP).

The first step is confirming you meet the basic requirement: you must be enrolled in an HDHP and have no other health coverage that would disqualify you. Once you've verified that, you can choose where to open the account. If your employer offers an HSA plan, that's usually the simplest route because payroll deductions happen automatically. If not, you can open one independently at any bank or financial institution that offers HSAs.

Key Takeaways

  • You must be enrolled in a high-deductible health plan (HDHP) to open an HSA, and you cannot have other health coverage like a spouse's plan or Medicare.
  • HSAs are offered by banks, credit unions, and insurance companies — your employer may offer one through payroll, but you can also open one independently.
  • The application process takes about 15 minutes and requires proof of HDHP enrollment, usually a copy of your plan documents or a letter from your insurer.
  • You can contribute money through payroll deductions (if your employer offers it), direct transfers, or by depositing checks, and contributions are tax-deductible either way.
  • Once the account is open, you can use a debit card or reimbursement requests to pay for may have access to medical expenses, and unused money rolls over year to year.

Verify your HDHP coverage before you apply

Your HDHP is the foundation of HSA may be able to access. You need to confirm two things: that your plan meets the IRS definition of a high-deductible plan, and that you have no other coverage that would disqualify you. Most plans sold as "HSA-compatible" or "HSA-may be able to access" already meet the IRS requirements, but it's worth checking your plan documents or calling your insurer to be certain.

The IRS sets minimum deductibles and maximum out-of-pocket limits that change each year. For 2024, an individual HDHP must have a deductible of at least $1,600 and out-of-pocket maximum of $8,050 or less. For family coverage, the deductible must be at least $3,200 and the out-of-pocket maximum $16,100 or less. Your insurer can tell you whether your specific plan qualifies.

You also cannot have other health coverage at the same time. This includes a spouse's employer plan, Medicare, Medicaid, TRICARE, or the VA. If you're married and your spouse has a traditional health plan, you cannot open an HSA — your spouse could open one if they're on an HDHP, but you cannot both be covered under different plans and both have HSAs.

Choose where to open your account

If your employer offers an HSA through payroll, that's usually the easiest option. Contributions come straight from your paycheck before taxes, and your employer may even contribute money on your behalf. You'll receive enrollment materials during open enrollment or when you first become may be able to access, and you can choose the HSA provider your employer has partnered with.

If your employer doesn't offer an HSA, or if you're self-employed, you can open one independently at any bank, credit union, or insurance company that administers HSAs. Common providers include major banks like Chase and Bank of America, credit unions, and dedicated HSA administrators like HealthEquity, Lively, and Fidelity. Compare them on fees (some charge monthly maintenance fees, others don't), investment options (if you want to invest HSA money rather than keep it in cash), and whether they offer a debit card for easy spending.

The account itself is separate from your health insurance. Your insurer doesn't control it, and switching insurers doesn't affect your HSA. You keep the same account and the same money regardless of which HDHP you're on.

Gather the documents you'll need

When you apply, you'll need to prove you're enrolled in an HDHP. Most providers accept one of these: a copy of your health plan's summary of benefits and coverage (SBC), a letter from your insurer confirming HDHP enrollment, or your insurance ID card. You don't need to submit these documents upfront — most providers ask you to confirm your HDHP status during the application, and they may verify it later.

You'll also need standard identification information: your Social Security number, date of birth, and address. If you're opening the account through an employer, your employer will have already confirmed your may be able to access, so you may only need to fill out an enrollment form.

Complete the application and set up contributions

The application itself is straightforward. You'll provide your personal information, confirm your HDHP enrollment, and choose how you want to fund the account. If you're opening it through payroll, you'll specify how much to contribute from each paycheck. If you're opening it independently, you'll set up a bank transfer or decide to deposit money manually.

Once the account is open, you can start contributing immediately. The IRS sets annual contribution limits that change each year — for 2024, you can contribute up to $4,150 for individual coverage or $8,300 for family coverage. If you're 55 or older, you can add an extra $1,000 per year. These limits apply to all your HSAs combined, so if you have multiple accounts, the total across all of them cannot exceed the limit.

Contributions made through payroll are deducted before taxes, which reduces your taxable income. If you contribute independently, you can deduct the contributions on your tax return. Either way, the money goes in tax-free.

Activate your debit card and start using the account

Most HSA providers issue a debit card that you can use to pay for may have access to medical expenses directly at the pharmacy, doctor's office, or medical supply store. The card works like any other debit card, but it only draws from your HSA balance. Some providers activate the card automatically when your account opens; others require you to activate it online or by phone.

You can also pay for may have access to expenses out of pocket and then request reimbursement from your HSA. This is useful if you want to let the money grow and invest it, or if you're paying with a credit card and want to keep the HSA balance intact. Keep receipts for any expenses you reimburse yourself for — the IRS requires documentation if you're ever audited.

may have access to medical expenses include copays, coinsurance, deductibles, prescription medications, dental work, vision care, and many other health-related costs. They do not include health insurance premiums (with a few exceptions), over-the-counter medications without a prescription, or cosmetic procedures. Your HSA provider's website has a full list of what counts.

Understand the investment and rollover rules

Unlike a flexible spending account (FSA), an HSA does not have a "use it or lose it" rule. Money you don't spend in a given year stays in the account and rolls over indefinitely. This makes an HSA a long-term savings tool — you can let the balance grow year after year and use it for medical expenses whenever you need to.

Many HSA providers let you invest your balance in mutual funds or other investments, similar to a 401(k). This is optional — you can keep the money in a cash account if you prefer. If you invest, you pay capital gains taxes on earnings when you withdraw the money, but only on the gains, not on the original contributions or the growth if you use it for may have access to medical expenses.

If you leave your job or change health plans, your HSA stays with you. You own the account and the money in it, regardless of what happens with your insurance or employment. You can keep contributing to it as long as you remain enrolled in an HDHP, even if you change employers or insurers.

Frequently Asked Questions

Can I open an HSA if my employer doesn't offer one?

Yes. You can open an HSA independently at any bank, credit union, or HSA administrator that offers accounts to individuals. You'll need to prove you're enrolled in an HDHP, but the process is the same as opening any other bank account. Some providers charge monthly fees, so compare options before choosing.

What happens to my HSA if I change jobs?

Your HSA stays with you and belongs to you, not your employer. The money and the account remain yours even if you leave the job or stop contributing. You can keep the same account or transfer it to a new provider if you prefer, and you can continue contributing as long as you're enrolled in an HDHP.

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

Yes, if your spouse is covered under your family HDHP plan. You can use HSA money for any may have access to medical expenses of you, your spouse, or your dependents, regardless of whose name is on the account. If your spouse has their own separate HDHP, they would need their own HSA.

Do I have to use the debit card, or can I pay out of pocket and reimburse myself?

You can do either. Some people use the debit card for convenience, while others pay with a personal credit card or cash and request reimbursement later. Reimbursing yourself lets you keep the HSA balance invested longer. Keep receipts for any expenses you reimburse, as the IRS requires documentation.

What if I don't use all my HSA money in a year?

The money rolls over to the next year with no limit. Unlike a flexible spending account, there's no deadline to spend it or lose it. You can let your HSA balance grow indefinitely and use it for medical expenses whenever they occur, even years later.
