You open an HSA through a bank, credit union, or insurance company—not through your employer, even though they may offer one

Your employer cannot hold your HSA for you. They can tell you which institutions offer HSAs and may even contribute money to your account, but the account itself lives at a financial institution you choose. You can open an HSA at the same bank where you have a checking account, at a different bank entirely, at a credit union, or through the health insurance company itself if they offer HSA custodial services.

The institution you pick becomes your HSA custodian—the entity responsible for holding the money, tracking contributions, and reporting to the IRS. Some custodians charge monthly fees, some charge per transaction, and some charge nothing. The money is yours regardless of where you open it, and you can move it to a different custodian later if you find better terms.

Key Takeaways

  • Banks, credit unions, and insurance companies all offer HSA accounts, and you choose which one rather than your employer choosing for you.
  • Your employer may contribute to your HSA or offer a payroll deduction option, but the account must be opened at a financial institution.
  • Monthly fees, investment options, and debit card availability vary widely between custodians, so comparing a few options before opening saves money over time.
  • You can open an HSA only if you are enrolled in a high-deductible health plan, and you must verify this with your insurance company before approaching a custodian.
  • Once you open an account, you can move the money to a different custodian at any time without losing the funds or triggering taxes.

Verify your high-deductible health plan enrollment first

Before you contact any financial institution, confirm that you are actually enrolled in a high-deductible health plan (HDHP). Your employer's benefits materials should state this clearly, or you can call your insurance company's customer service line and ask directly. The representative can tell you the exact deductible amount and whether the plan qualifies for HSA contributions under IRS rules.

This step matters because you cannot open an HSA unless you have an HDHP in place. If you are on a standard PPO or HMO plan, you are not may be able to access, and no custodian will open an account for you. If you are between jobs or between insurance plans, you can still open an HSA as long as you enroll in an HDHP before making contributions.

Compare custodians on fees, investment options, and access

Different custodians charge different amounts and offer different features. A bank might charge $3 per month but offer no investment options beyond a savings account. A brokerage might charge nothing monthly but require a $1,000 minimum balance to invest. An insurance company might waive fees if you use their debit card but charge per transaction if you withdraw cash.

Before opening, ask each custodian about monthly maintenance fees, per-transaction fees, investment options (if you want to invest rather than hold cash), debit card availability, and whether they offer online access. If you plan to use the account only for near-term medical expenses, a low-fee savings account at a bank is usually the simplest choice. If you plan to let the money grow for years, investment options and low fees matter more.

You can find HSA custodians through your employer's benefits website, through your health insurance company's website, or by searching "HSA custodian" and comparing the major options: Fidelity, Lively, HealthEquity, Optum, and regional banks all offer HSA accounts. Read the fee schedule and terms of service for at least two or three before deciding.

Open the account online or in person with your HDHP information

Most custodians let you open an HSA online in 10 to 15 minutes. You will need your name, address, Social Security number, and information about your HDHP—usually the plan name, your policy number, and the deductible amount. Some custodians verify this information automatically; others ask you to upload a copy of your insurance card or benefits summary.

If you prefer to open in person, you can visit a local bank branch or credit union and ask to open an HSA. Bring your insurance card and a photo ID. The process is the same as opening any other account, except the custodian will ask which HDHP you are enrolled in and may verify it before finalizing the account.

Once the account is open, you receive an account number and routing number (if it is a bank account) or login credentials for online access. Some custodians issue a debit card when ready; others mail it within a week. You can begin making contributions as soon as the account is active, even if the debit card has not arrived yet.

Set up payroll deductions through your employer if available

If your employer offers HSA payroll deductions, you can authorize them to move money directly from your paycheck into your HSA before taxes are withheld. This reduces your taxable income and is usually the fastest way to fund the account. You typically set this up through your employer's benefits portal or by submitting a form to payroll.

Payroll deductions are optional—you can also fund your HSA by transferring money from your bank account or by writing a check. However, payroll deductions are more convenient and give you an when ready tax break on the money you contribute. If your employer matches contributions (some do), payroll deduction is the only way to receive the match.

You can change your payroll deduction amount or stop it at any time, usually during open enrollment or by submitting a change form to payroll. The money already in your HSA stays there regardless of whether you continue contributing.

Understand what happens if you change jobs or insurance

Your HSA belongs to you, not your employer or your insurance company. If you change jobs, you keep the account and the money in it. You can continue contributing if your new employer's plan is also an HDHP, or you can stop contributing and straightforward use the existing balance for medical expenses.

If you switch to a non-HDHP plan (such as a standard PPO), you can no longer make new contributions, but you keep the account and can withdraw money for medical expenses tax-free. The money does not expire and does not disappear when you change insurance.

If you want to move your HSA to a different custodian—for example, from your bank to a brokerage with lower fees—you can do a trustee-to-trustee transfer. Contact the new custodian and ask them to initiate the transfer. The money moves directly between institutions without passing through your hands, so there are no tax consequences and no contribution limits triggered.

Make your first contribution and track it for taxes

Once your account is open, you can contribute money when ready. For 2024, the IRS limits are $4,150 for individual coverage and $8,300 for family coverage (these amounts change yearly). If you are 55 or older, you can contribute an additional $1,000 per year.

Keep records of all contributions you make, especially if you contribute outside of payroll. Your custodian will send you a Form 5498-SA each year showing contributions made to your account. You will need this for your tax return if you claim the deduction yourself rather than using payroll deductions.

You can contribute until the tax filing important date (usually April 15 of the following year) for the prior year. For example, you can contribute to your 2024 HSA until April 15, 2025. Your custodian will help you track this if you ask.
