Banks, brokerages, and your health plan all offer HSAs
You can open a health savings account through your employer's plan administrator, your health insurance company, a bank, or an independent brokerage firm. The account itself is separate from your insurance — you own it and control the money in it — but you must be enrolled in a high-deductible health plan (HDHP) to contribute. Most people open an HSA through whichever institution their employer or insurer recommends, but you can also shop for better fees or investment options by opening one independently.
The three main routes are employer-sponsored (often the easiest), insurance-company-affiliated (convenient if you buy your own coverage), and independent financial institutions (best if you want to invest the balance rather than just save it). Each has different fee structures, investment choices, and customer service options. Your choice matters because HSA fees can eat into your balance over time, and investment options determine whether your money grows or sits idle.
Key Takeaways
- Most people open an HSA through their employer's plan or their health insurance company, which requires no shopping and often waives fees for employees.
- Banks and brokerages offer HSAs with lower fees and more investment options, but you must already be enrolled in an HDHP to open one.
- HSA fees vary widely — some institutions charge monthly maintenance fees, per-transaction fees, or investment management fees that can total $50 to $200 per year.
- You can open an HSA at one institution and later transfer the balance to another if you find better terms, though the process takes 20 to 30 days.
Opening an HSA through your employer
If your employer offers a high-deductible health plan, they almost always offer an HSA through a third-party administrator — companies like Fidelity, HealthEquity, Lively, or Optum. You enroll during open enrollment or when you first become may be able to access, usually through your benefits portal or HR department. The employer typically covers or subsidizes the account maintenance fee, so you pay nothing to open or maintain it.
This route is the fastest and cheapest for most people. You do not need to shop around or verify your HDHP may be able to access — your employer has already done that. Contributions are deducted from your paycheck before taxes, which saves you money automatically. The downside is limited choice: you get whatever institution and investment options your employer selected, and you cannot switch without leaving the job or waiting until the next open enrollment period.
Opening an HSA through your health insurance company
If you buy your own health insurance (not through an employer), your insurer often offers an HSA directly or partners with an administrator like Optum or Fidelity. You can open the account when you enroll in the HDHP, usually on the insurer's website or by phone. The insurer verifies your HDHP enrollment automatically, so you do not need to submit proof.
This option is straightforward if you already have your insurance set up. However, insurance-company HSAs sometimes charge higher fees than independent options, and investment choices may be limited to a few mutual funds or money market accounts. If you want to invest your HSA balance aggressively, an independent brokerage may offer better options. You can always open a separate HSA elsewhere and roll your balance over later if you find better terms.
Opening an HSA at a bank or credit union
Banks and credit unions offer HSAs as deposit accounts, similar to savings accounts. You can open one at institutions like Ally, Charles Schwab, Fidelity, or your local credit union. You will need to provide proof of HDHP enrollment — usually a copy of your insurance card or a letter from your insurer confirming your plan type. The process takes 5 to 10 minutes online or in person.
Bank HSAs typically have lower monthly fees (often $0 to $5) than insurance-company options, and some waive fees if you maintain a minimum balance. The tradeoff is that bank HSAs usually offer only savings accounts or money market funds, not stock or bond investments. This works well if you plan to spend your HSA money on current medical expenses. If you want to invest for long-term growth, a brokerage HSA is a better fit.
Opening an HSA at a brokerage or investment firm
Brokerages like Fidelity, Schwab, Vanguard, and E-Trade offer HSAs that function like investment accounts. You can hold stocks, bonds, mutual funds, and exchange-traded funds (ETFs) inside the HSA, which means your balance can grow tax-free over time. You open the account online, provide proof of HDHP enrollment, and link a bank account for contributions.
Brokerage HSAs are best for people who do not plan to spend their HSA money immediately and want to build long-term savings for retirement medical expenses. Fees vary: some brokerages charge no account maintenance fee but may charge per-transaction fees or require a minimum balance. Others charge a flat annual fee ($50 to $100) but offer unlimited trading. Compare the fee structure against your expected contribution and trading frequency before opening.
What to compare when choosing where to open an HSA
| Factor | What to Look For |
|---|---|
| Monthly or annual fees | Some institutions charge $0; others charge $2 to $10 per month. Over 10 years, a $5 monthly fee costs $600. |
| Investment options | Banks offer savings accounts only. Brokerages offer stocks, bonds, and funds. Choose based on whether you plan to invest or just save. |
| Debit card access | Some HSAs include a debit card for direct medical payments. Others require you to pay out of pocket and reimburse yourself later. |
| Customer service | Phone support, online chat, and mobile apps vary widely. Test the support channel before opening if you think you will need help. |
| Ease of transfers | If you think you might switch institutions later, confirm the process for rolling over your balance. Most take 20 to 30 days. |
Do not choose based on brand name alone. A well-known bank may charge higher HSA fees than a smaller competitor. Use the fee calculator on each institution's website to estimate your annual cost, then subtract that from your expected contribution to see the real impact on your savings.
Moving your HSA to a different institution
You can transfer your HSA balance from one institution to another at any time, even mid-year. This is called a trustee-to-trustee transfer, and it does not count as a withdrawal or distribution. The money moves directly between institutions without touching your hands, so there are no tax consequences.
The process takes 20 to 30 days. You contact the new institution, provide your old HSA account details, and they handle the paperwork. Your old institution will close the account once the balance is transferred. Some institutions charge a transfer fee ($25 to $50), so ask before you start. If you have a debit card linked to the old account, stop using it before the transfer completes to avoid declined transactions.
Frequently Asked Questions
Can I open an HSA if my employer does not offer one?
Yes. You can open an HSA independently at a bank or brokerage as long as you are enrolled in an HDHP. You will need to provide proof of your HDHP enrollment, usually a copy of your insurance card or a letter from your insurer. You will also need to make contributions yourself rather than through payroll deduction, which means you do not get the automatic tax savings.
Do I need to open an HSA with the same company that administers my employer's plan?
No. You can open a separate HSA at any institution that offers them. Some people do this to get better investment options or lower fees. You can contribute to both accounts in the same year as long as your total contributions do not exceed the annual limit set by the IRS.
What happens to my HSA if I change jobs?
Your HSA stays with you and remains yours to keep. You do not have to close it or move the balance. If your new employer offers an HSA through a different administrator, you can keep your old account and open a new one, or transfer the old balance to the new one. The money is always yours, regardless of employment.
Can I open an HSA online, or do I have to go to a branch?
Most institutions allow you to open an HSA entirely online. You provide your personal information, proof of HDHP enrollment, and bank details for contributions. A few smaller banks or credit unions may require an in-person visit, but this is rare. Check the institution's website to confirm the process before you start.
What if I open an HSA and then lose my HDHP coverage?
You can keep the account and the money in it, but you cannot make new contributions once you are no longer enrolled in an HDHP. You can still withdraw money for medical expenses tax-free. If you withdraw money for non-medical expenses, you owe income tax plus a 20 percent penalty on the amount withdrawn.
