Most banks offer HSAs, but the account itself comes from a separate HSA custodian

When you open a health savings account, you are not opening it at your regular bank the way you would a checking account. Instead, you open it through an HSA custodian — a financial company licensed specifically to hold HSA funds. Your bank may partner with an HSA custodian and offer HSA accounts under its name, but the actual account is managed by the custodian behind the scenes.

This matters because it means you have two separate choices to make: which custodian to use, and whether you want that custodian's account to be connected to your main bank. Some people choose a custodian their employer recommends. Others choose based on fees, investment options, or customer service. Your bank's involvement is optional — it is a convenience, not a requirement.

Key Takeaways

  • HSA custodians are specialized financial companies, not regular banks, though many banks partner with custodians to offer HSA accounts under their brand.
  • Large banks like Chase, Bank of America, and Wells Fargo offer HSAs through partnerships, but you can also open directly with independent custodians like Fidelity, Lively, or HealthEquity.
  • Your employer may have already chosen a custodian for you; check your benefits paperwork before opening a new account elsewhere.
  • Fees, investment choices, and ease of use vary significantly between custodians, so comparing a few options before opening is worth the time.
  • You can move your HSA to a different custodian later if you find better terms, though the process takes a few weeks.

Large banks that offer HSAs through partnerships

Chase, Bank of America, Wells Fargo, and Citibank all offer HSA accounts, but they do this by partnering with a custodian rather than managing the accounts themselves. Chase partners with HealthEquity. Bank of America uses Ascensus. The specific partner can change, so if you want to open through your bank, call the bank's benefits line or check their website to confirm the current custodian.

The advantage of opening through your bank is simplicity: your HSA sits in the same login as your checking account, and transfers between them are straightforward. The disadvantage is that you are limited to whatever investment options and fee structure that bank's partner custodian offers. You cannot shop around as easily.

Independent HSA custodians you can open with directly

You do not need to use your bank's HSA partner. You can open directly with an independent custodian instead. The largest independent custodians are Fidelity, HealthEquity, Lively, Optum Bank, and Ascensus. Each has its own fee structure, investment menu, and user interface.

Fidelity is known for low fees and a wide range of investment options — you can invest HSA funds in stocks, bonds, and mutual funds the same way you would in a regular brokerage account. HealthEquity and Lively focus on ease of use and low or no monthly fees. Optum Bank is owned by a health insurance company and integrates with some health plans. Ascensus is large but less visible to individual consumers.

Opening directly with an independent custodian means your HSA is separate from your bank account, so you will manage it in a different login. Transfers between your bank and your HSA take a few business days instead of being when ready. For some people, this separation is actually helpful — it makes the HSA feel like a dedicated savings account rather than money you might accidentally spend.

What to check before choosing a custodian

Monthly or annual fees vary. Some custodians charge nothing if you keep a minimum balance (often $1,000 to $2,500). Others charge a flat fee regardless of balance. A few charge per transaction. Over a year, the difference between a $0 fee custodian and one charging $10 per month is $120 — money that could have stayed in your account.

Investment options matter if you plan to invest your HSA rather than just use it as a checking account. If you want to buy individual stocks or index funds, you need a custodian that offers a brokerage platform. If you only want a savings account earning interest, you need one with a competitive savings rate. Some custodians offer both; others offer only one.

Debit card access and online transfers are conveniences worth checking. Can you withdraw money with a debit card at any ATM, or only at certain ones? Can you transfer money to your regular bank account online, or do you have to request a check? These small differences add up if you use your HSA regularly for medical expenses.

If your employer chose a custodian for you

Many employers set up an HSA through a specific custodian as part of their benefits package. If this is the case, you will receive paperwork or an email with instructions to open your account with that custodian. You are not required to use your employer's choice — you can open elsewhere — but there is often a reason employers choose one: they may have negotiated lower fees, or the custodian integrates with the employer's payroll system so contributions are deducted automatically before taxes.

Before opening a separate account, check whether your employer's custodian offers what you need. If it does not, you can open a second HSA with a different custodian, though you will need to track contributions across both accounts to stay under the annual limit. Most people find it simpler to stick with one.

Moving your HSA to a different custodian later

If you open an HSA with one custodian and later find a better option, you can move the account. This is called a custodian-to-custodian transfer. The new custodian handles most of the paperwork — you request the transfer on their website, they contact your old custodian, and the funds move over. The process usually takes two to four weeks.

You can do this as often as you want, though doing it frequently is inconvenient. There is no limit on how many times you can transfer. Some people transfer once when they change jobs and their employer switches custodians. Others transfer when they find a custodian with lower fees or better investment options. Plan to do it only when the benefit is worth the waiting period.

Credit unions and smaller banks

Some credit unions and regional banks offer HSAs, usually through a partnership with one of the major custodians. If you bank with a credit union or smaller institution, ask whether they offer HSA accounts and which custodian they use. The terms may be different from what a large bank offers — sometimes better, sometimes worse.

If your bank or credit union does not offer an HSA, you can still open one with any independent custodian. Your HSA does not have to be at the same institution as your checking account.

Frequently Asked Questions

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

Technically yes, but the IRS limits your total contributions across all HSAs to one annual amount. If you have two accounts, you have to track contributions in both to avoid exceeding the limit and facing a tax penalty. Most people keep only one HSA to avoid this complication.

What happens to my HSA if I change jobs?

Your HSA stays yours. It does not belong to your employer. If your new employer uses a different custodian, you can keep your old account open or transfer the balance to the new custodian. You are never forced to move your HSA.

Do I need a health insurance plan from the same company as my HSA custodian?

No. Your HSA custodian and your health insurance company are separate. You can have an HSA with Fidelity and health insurance with any company, as long as your health plan qualifies as a high-deductible health plan.

What if I want to invest my HSA but my custodian does not offer investments?

You can transfer your HSA to a custodian that does offer investments. Fidelity and some others let you invest in stocks and mutual funds. If you want to keep your current custodian for other reasons, ask whether they have added investment options recently — some custodians have expanded their offerings.

Are there fees for transferring my HSA to a new custodian?

The new custodian usually covers the transfer cost. Your old custodian may charge a small fee (typically $25 to $50) for processing the request, though many waive it. Ask both custodians about their transfer fees before you start the process.
