You can open an HSA through your health insurance plan, a bank, or a financial institution that specializes in HSAs

The most common route is through your employer's health plan if you have one. When you enroll in a high-deductible health plan (HDHP), your employer usually offers HSA options as part of that enrollment — often through a specific bank or financial company they've partnered with. You'll see the HSA provider listed in your plan documents or enrollment materials.

If you don't have employer coverage or your employer doesn't offer an HSA, you can open one independently through a bank, credit union, or a dedicated HSA provider. Banks like Fidelity, Lively, HealthEquity, and Optum Bank all offer HSAs to individuals. You'll need to have your own HDHP coverage first — you cannot open an HSA without being enrolled in a may have access to high-deductible plan.

The provider you choose affects how much you pay in fees, what investment options are available, and how easy it is to spend the money. Some providers charge monthly maintenance fees; others charge per transaction. Some offer investment accounts for money you don't spend immediately; others keep your balance in a savings account earning minimal interest.

Key Takeaways

  • If you have employer coverage with an HDHP, your employer will tell you which HSA provider to use during open enrollment.
  • If you buy your own HDHP through the health insurance marketplace, you can open an HSA with any provider that accepts your plan type.
  • You must be enrolled in a may have access to high-deductible health plan before you can open an HSA — the account cannot exist without active HDHP coverage.
  • Compare providers on monthly fees, transaction costs, investment options, and how you access your money (debit card, checks, transfers).
  • You can change HSA providers at any time, though moving money between accounts takes a few weeks.

Opening an HSA through your employer

During your company's open enrollment period — usually once a year in fall or early winter — you'll see HSA options listed alongside HDHP plans. The enrollment materials will name the HSA provider your employer has selected. You don't choose the provider; you choose whether to open an account with the one your employer offers.

Once you enroll in the HDHP, you can usually open the HSA account the same day or within a few days through the provider's website or a link in your enrollment confirmation. You'll need your Social Security number, date of birth, and address. Some employers allow payroll deduction, which means your HSA contributions come straight from your paycheck before taxes — this is the fastest way to fund the account.

If your employer offers multiple HDHP plans with different deductibles, each plan may have the same HSA provider, or different plans may use different providers. Check your plan documents to see which provider goes with which plan.

Opening an HSA if you buy your own health insurance

If you purchase an HDHP through the health insurance marketplace (Healthcare.gov or your state's marketplace), you can open an HSA with any provider that accepts your plan. You are not locked into one provider. This means you can shop around for the best fees and features before opening an account.

You'll need proof of your HDHP coverage to open the account. Most providers ask for your policy number or a screenshot of your coverage confirmation. Have this information ready before you start the application.

If you're self-employed or have a spouse with self-employed income, you can also open an HSA as long as you're covered by an HDHP. The process is the same: enroll in the HDHP first, then open the HSA account with a provider of your choice.

Comparing HSA providers on fees and features

Monthly maintenance fees range from zero to around $5 per month, depending on the provider and your account balance. Some providers waive fees if you maintain a minimum balance (often $1,000 to $2,500) or if you set up direct deposit. Others charge per transaction — for example, $1 to $3 each time you use the debit card or write a check.

Investment options matter if you plan to let money grow in your HSA rather than spend it each year. Some providers offer mutual funds, index funds, or brokerage accounts; others keep your balance in a savings account only. If you want to invest, confirm the provider offers this and what the investment fees are.

Access to your money also varies. Most providers issue a debit card you can use at pharmacies and medical providers. Some allow online transfers to your bank account, checks, or mobile payment apps. If you have a specific way you want to spend the money, check whether the provider supports it.

Read the provider's fee schedule before you open the account. It's usually on their website under "Fees" or "Pricing." You can change providers later if you find a better option, though the transfer takes two to four weeks.

What you need to open an account

You'll need your Social Security number, date of birth, current address, and proof of HDHP coverage. Your proof of coverage is usually your policy number or a screenshot of your enrollment confirmation from your insurance company or marketplace account.

If you're opening an account through your employer, you may not need to provide proof of coverage — the employer's system already knows you're enrolled in an HDHP. If you're opening an account independently, have your policy information ready.

Some providers ask for your employer's name and address if you have employer coverage. This is for their records and does not affect your account.

Funding your HSA

If your employer offers payroll deduction, this is usually the fastest and simplest way to fund your account. You choose how much to contribute each pay period, and the money goes directly into your HSA before taxes are taken out. You can change your contribution amount during open enrollment or if you have a may have access to life event (marriage, birth, loss of coverage).

If you don't have payroll deduction, you can transfer money from your bank account to your HSA using the provider's website or mobile app. This typically takes one to three business days. You can also mail a check to the provider, though this is slower.

There's an annual contribution limit set by the IRS. For 2024, the limit is $4,150 for individual coverage and $8,300 for family coverage. These limits change each year. You can contribute up to this limit across all HSAs you own — if you have multiple accounts, the total cannot exceed the limit.

Changing HSA providers

You can move your HSA to a different provider at any time. This is called a trustee-to-trustee transfer. Contact your new provider and ask them to initiate the transfer. They'll handle the paperwork with your old provider. The transfer usually takes two to four weeks, and your money stays in the account the entire time — you don't lose access to it.

You can also do a rollover, where you withdraw money from your old HSA and deposit it into a new one within 60 days. This is riskier because if you miss the 60-day window, the money is taxed and penalized. A trustee-to-trustee transfer is safer and simpler.

If you leave your job, you keep your HSA. It doesn't disappear or revert to your employer. You can leave the money where it is, transfer it to a new provider, or continue using it with the same provider even after you leave the company.

Frequently Asked Questions

Can I have more than one HSA at the same time?

Yes, but your total contributions across all accounts cannot exceed the annual IRS limit. If you have two HSAs and contribute $2,000 to each, you've hit the $4,150 individual limit. Track your total contributions carefully to avoid overfunding, which triggers taxes and penalties on the excess.

What happens to my HSA if I lose my HDHP coverage?

Your HSA stays open and the money remains yours. You can continue to spend it on medical expenses tax-free. You just can't make new contributions once you're no longer covered by an HDHP. If you re-enroll in an HDHP later, you can start contributing again.

Do I have to use the HSA provider my employer chose?

If you have employer coverage, your employer selects the provider and you use that one for payroll deduction. However, you can open a separate HSA with a different provider and fund it yourself with after-tax money, then reimburse yourself from that account. Most people stick with their employer's provider for simplicity.

Can I open an HSA if I'm on Medicare?

No. Once you enroll in Medicare, you're no longer may be able to access to contribute to an HSA. You can keep an existing HSA and spend the money on medical expenses, but you cannot make new contributions. If you're not yet on Medicare but approaching 65, check with your HSA provider about contribution rules in your final working year.

How do I know if my health plan qualifies as an HDHP?

Your insurance company or employer will tell you whether your plan is an HDHP. Look for the term "high-deductible health plan" or "HDHP" in your plan documents. If you're unsure, call your insurance company's customer service line and ask directly — they can confirm in one call.
