You can open an HSA through your employer's plan, a bank, or an insurance company — each route has different costs and features
An HSA (Health Savings Account) is a tax-advantaged savings account, but you cannot open one on your own. You must first be enrolled in a high-deductible health plan (HDHP). Once you meet that requirement, you have three main routes: open an HSA through your employer if they offer one, open one at a bank or credit union, or open one through an insurance company or third-party administrator. The route you choose affects what fees you pay, how easy the account is to use, and what investment options are available to you.
Key Takeaways
- You must be enrolled in an HDHP before opening an HSA; the account itself is separate from your health insurance.
- Employer-sponsored HSAs often have lower fees and automatic payroll deduction, but you lose access to the account if you leave the job.
- Bank and credit union HSAs give you portability and control but may charge monthly maintenance fees or require a minimum balance.
- Insurance company HSAs are sometimes bundled with your HDHP but often have higher fees and limited investment choices than banks.
- You can move money between HSA providers at any time, so choosing your first provider is not permanent.
Opening an HSA through your employer
If your employer offers an HDHP with an HSA option, this is usually the simplest and cheapest route. Your employer contracts with a third-party administrator (often companies like Fidelity, HealthEquity, or Lively) to manage the account. You enroll during your company's open enrollment period or when you first become may be able to access, and contributions are deducted from your paycheck before taxes. This means you avoid federal income tax, Social Security tax, and Medicare tax on the money you contribute.
The main advantage is cost: employer-sponsored plans typically charge no monthly maintenance fee or a very low one, because your employer negotiates rates for all employees. The main disadvantage is portability. If you leave the job, you keep the money in the account, but you may lose access to the employer's HSA provider. Some employers allow former employees to keep accounts open; others require you to roll the balance to a different provider within a set timeframe (often 30 to 60 days). Check your plan documents or ask your benefits administrator what happens to your account if you leave.
Opening an HSA at a bank or credit union
Banks and credit unions offer HSAs as standalone accounts. You open one directly with the institution, and you control the account entirely. This is the most portable option: you keep the same account and the same money whether you change jobs, leave a job, or retire. You also have full choice over where your money is invested — most banks offer HSA accounts that function like checking or savings accounts, and some offer investment options like mutual funds or stocks.
The trade-off is fees. Banks typically charge a monthly maintenance fee (ranging from $0 to $5 per month, depending on the institution), and some require a minimum balance to waive the fee. A few banks charge per-transaction fees or fees for paper statements. Before opening an account, compare the fee structure across several banks. Some credit unions offer HSAs with no monthly fee, which can save you $60 per year compared to a bank that charges $5 per month. You will also need to handle your own tax deduction if you contribute outside of payroll — you claim the deduction on your tax return using IRS Form 8889.
Opening an HSA through an insurance company or third-party administrator
Many insurance companies bundle an HSA with their HDHP. When you enroll in the health plan, you are often automatically enrolled in their HSA unless you opt out. Third-party administrators like HealthEquity, Fidelity, and Lively also offer HSAs directly to individuals and to employers. These accounts are portable: you keep the account even if you change health plans or jobs.
Insurance company HSAs often have higher monthly fees than banks (sometimes $2 to $5 per month) and may limit your investment options to a small menu of mutual funds or a money market fund. However, some insurance companies waive fees if you maintain a minimum balance, and some offer no-fee accounts if you enroll through your employer. Third-party administrators vary widely: some charge no monthly fee and offer robust investment options, while others charge $2 to $3 per month. Read the fee schedule carefully before opening an account, because fees compound over time and reduce the tax benefit of the account.
Comparing providers side by side
| Provider Type | Monthly Fee | Portability | Investment Options | Best For |
|---|---|---|---|---|
| Employer-sponsored | Usually $0–$2 | Limited (depends on employer) | Varies by administrator | Lowest cost if you stay at the job |
| Bank or credit union | $0–$5 | Full (you keep the account) | Checking, savings, investments | Maximum control and portability |
| Insurance company | $2–$5 | Full (you keep the account) | Limited menu | Convenience if bundled with your plan |
| Third-party administrator | $0–$3 | Full (you keep the account) | Varies (some robust, some limited) | Flexibility and lower fees |
What to check before you open an account
Before opening an HSA with any provider, verify that you are enrolled in an HDHP. The IRS defines an HDHP by its deductible and out-of-pocket limits; if your plan does not meet those thresholds, you cannot open an HSA. Your health insurance documents or your employer's benefits materials will state whether your plan is HDHP-may be able to access.
Next, compare fees across at least two or three providers. A $3 monthly fee sounds small, but it costs $36 per year and reduces your account balance over decades. Look for accounts with no monthly maintenance fee, no minimum balance requirement, and no per-transaction fees. If you plan to invest your HSA money (rather than keep it in cash), check what investment options each provider offers and whether there are fees to buy or sell investments.
Finally, ask about portability. If you are opening an employer-sponsored account, ask your benefits administrator what happens to your account if you leave the company. If you are opening an account at a bank or insurance company, confirm that you own the account and can keep it open even if you change health plans or jobs.
Moving money between HSA providers
You are not locked into your first choice. You can move your HSA balance from one provider to another at any time through a trustee-to-trustee transfer. The money moves directly from the old account to the new one without touching your hands, so there are no tax consequences and no annual contribution limits triggered. The process usually takes 5 to 10 business days.
Some people open an HSA through their employer for the payroll deduction convenience, then move the balance to a bank or third-party administrator after a year or two to reduce fees or gain better investment options. Others start with a bank account and move to an employer plan if they change jobs and their new employer offers a lower-fee option. You can make as many transfers as you want, though some providers charge a small fee (usually $25 to $50) to process an outgoing transfer.
Frequently Asked Questions
Can I have more than one HSA at the same time?
No. The IRS limits you to one HSA per year. If you open a second account, you will have over-contributed, and you will owe taxes and penalties on the excess. If you want to switch providers, you must close the old account or move the balance via trustee-to-trustee transfer before opening a new one.
What if my employer does not offer an HSA?
You can open an HSA on your own at a bank, credit union, or third-party administrator, as long as you are enrolled in an HDHP. You will handle contributions yourself and claim the tax deduction on your tax return. You will also pay any monthly fees out of pocket, so compare providers to find the lowest-cost option.
Do I have to open an HSA with the same company that provides my health insurance?
No. Your HSA provider and your health insurance provider are separate. You can enroll in an HDHP from one company and open an HSA at a completely different bank or administrator. This gives you flexibility to choose the HSA provider with the lowest fees and best features, regardless of which insurance company you use.
What happens to my HSA if I change jobs?
If you have an employer-sponsored HSA, you keep the money in the account, but you may lose access to that specific provider. Check your plan documents to see whether you can keep the account open as a former employee or whether you must move the balance to a new provider. If you open an HSA at a bank or third-party administrator, you keep the account and the money no matter where you work.
Are there HSAs with no monthly fees?
Yes. Some credit unions, online banks, and third-party administrators offer HSAs with no monthly maintenance fee. However, they may require a minimum balance (often $1,000 to $2,500) to avoid fees, or they may charge fees for certain services like paper statements or investment transactions. Compare the full fee schedule, not just the monthly fee.
