You can open an HSA through your employer's plan, a bank, or an insurance broker — but only if you're enrolled in a high-deductible health plan

An HSA is not a standalone account you can open anywhere. It exists only as part of a high-deductible health plan (HDHP), so your first step is to be enrolled in one. If your employer offers an HDHP, they usually contract with a specific HSA provider — often a bank, credit union, or insurance company — and you open the account through that provider as part of enrollment. If you buy your own health insurance through the marketplace or a broker, you choose an HDHP first, and the insurer or broker will tell you which HSA provider is linked to that plan. Some people use multiple HSAs if they switch plans mid-year, though only one can be active at a time.

The HSA provider is separate from your health insurer. Your insurer handles medical claims; the HSA provider holds your money and processes withdrawals. A bank might be both, but they function as two different services. You need to know which entity you're dealing with for each task.

Key Takeaways

  • You can only open an HSA if you are enrolled in a high-deductible health plan, which is the legal requirement.
  • If your employer offers an HDHP, the HSA provider is usually chosen by your employer, and you enroll during benefits selection.
  • If you buy your own health insurance, you select the HDHP first, then open the HSA through the provider that plan uses.
  • Banks, credit unions, and insurance companies all offer HSAs, and you can compare them on fees, investment options, and customer service before enrollment closes.
  • Once you open an HSA, you can move money to a different HSA provider later, though the process takes a few weeks.

Opening an HSA through your employer

If your employer offers health insurance, they typically offer at least one HDHP option during open enrollment. When you select that plan, you are automatically offered an HSA through the provider your employer has contracted with. You do not choose the provider — your employer has already made that choice. You simply enroll in the HSA at the same time you enroll in the health plan, usually through your employer's benefits portal or during a benefits meeting.

Your employer may also offer a choice of HSA providers. Larger employers sometimes contract with two or three banks or insurance companies and let employees pick. If that is the case, compare them on monthly fees (some charge nothing, others charge $2 to $5 per month), investment options (if you plan to invest the money rather than spend it), and whether they offer a debit card for medical purchases. The enrollment window is usually 30 to 60 days, so you have time to look at each option before you decide.

Once you enroll, the HSA provider sends you login credentials and a debit card (if they offer one). Your employer may also make a contribution to your account — many do — and that money appears within a few business days. You can start using the account immediately, though it may take a week or two for all the paperwork to sync between your employer, the health insurer, and the HSA provider.

Opening an HSA when you buy your own health insurance

If you do not have employer health insurance, you buy a plan through the health insurance marketplace (healthcare.gov in most states) or through a broker. You must select an HDHP to open an HSA. When you choose that plan during checkout, the marketplace or broker will show you which HSA provider is linked to it. You then open the HSA account with that provider, either immediately or within a set window (usually 60 days after your plan starts).

The process differs slightly depending on where you buy. If you use healthcare.gov, you select the HDHP, complete enrollment, and then the marketplace provides contact information for the HSA provider. You log in to the provider's website or call them to open the account. If you use a broker or a private marketplace, the broker may open the HSA for you as part of the plan sale, or they may send you a link to do it yourself. Ask the broker which HSA providers are available for the plan you chose — some plans have only one, others have two or three.

You have until the end of the calendar year to open an HSA for a plan that started earlier in the year, though the sooner you open it, the sooner you can contribute and use it. If you miss the deadline, you can still open an HSA the following year when you renew or switch plans.

Comparing HSA providers before you enroll

If you have a choice of HSA providers, look at these factors: monthly or annual fees (some charge nothing, others charge $2 to $10 per month or a flat annual fee), whether they offer a debit card, investment options, and customer service availability. A provider with no fees but limited investment options may be better if you plan to spend the money on medical costs each year. A provider with investment options and higher fees may be better if you plan to save and invest the money long-term.

Check whether the provider charges a fee to transfer money out if you switch providers later. Some charge $25 to $50 for a trustee-to-trustee transfer. If you think you might switch jobs or plans, a provider with no transfer fee is worth choosing now. You can also ask the provider whether they offer a mobile app, online bill pay, or integration with accounting software if you are self-employed.

Most employers and insurers provide a comparison sheet or link to each provider's website during enrollment. Use it. If you cannot find one, call the provider directly and ask about fees and features. The enrollment window is your only chance to choose without paying a transfer fee later.

What happens after you open the account

Once your HSA is open, you receive a routing number and account number (like a checking account) and usually a debit card. You can deposit money by payroll deduction (if your employer offers it), by bank transfer, or by mailing a check. Payroll deduction is the easiest because it happens automatically and reduces your taxable income. If you are self-employed, you deposit money yourself and claim the deduction on your tax return.

You can withdraw money for may have access to medical expenses immediately. may have access to expenses include copays, coinsurance, deductibles, prescription drugs, dental work, vision care, and many other costs. They do not include health insurance premiums (with a few exceptions for COBRA or long-term care insurance). Keep receipts for all withdrawals in case the IRS asks for proof later.

If you switch jobs or change health plans, you can keep your HSA open and keep the money in it, even if you are no longer enrolled in an HDHP. However, you cannot make new contributions unless you are enrolled in an HDHP. You can also move the money to a different HSA provider by requesting a trustee-to-trustee transfer, which takes one to three weeks and may cost a fee.

Opening an HSA if you are self-employed or a contractor

If you buy your own health insurance as a self-employed person or contractor, you can open an HSA as long as your plan is an HDHP. You select the HDHP through the marketplace or a broker, then open the HSA with the linked provider. The process is the same as for any individual buyer, except you make contributions yourself rather than through payroll deduction.

You can contribute up to the annual limit set by the IRS (the limit varies by year and whether your plan covers one person or a family). You claim the contribution as a deduction on your tax return, either as an above-the-line deduction or as part of self-employment income, depending on your situation. A tax professional can advise you on the best approach for your business structure.

Some self-employed people use a solo 401(k) or SEP-IRA in addition to an HSA. An HSA is not a retirement account, but the money can be used for retirement medical expenses, so it complements other retirement savings. You can have both at the same time.

Moving your HSA to a different provider

If you want to switch HSA providers — because of fees, investment options, or customer service — you can do so by requesting a trustee-to-trustee transfer. You contact the new provider, provide them with your old provider's information, and they handle the transfer. The old provider sends all your money to the new provider, and you receive new login credentials and a debit card from the new provider.

The transfer usually takes one to three weeks. During that time, your money is in transit and you cannot access it, so plan ahead if you have upcoming medical expenses. Some providers charge a fee for outgoing transfers (typically $25 to $50), so check before you request the transfer. The new provider may also charge an incoming transfer fee, though many do not.

You can switch providers at any time, not just during open enrollment. However, if you switch while enrolled in an HDHP, you must move all the money — you cannot split it between two providers. If you leave your HDHP and later re-enroll in one, you can open a new HSA with a different provider, but you still own the old account and its money.

Frequently Asked Questions

Can I open an HSA without an employer?

Yes. You buy an HDHP through the health insurance marketplace or a broker, and the HSA provider is linked to that plan. You open the account directly with the provider. You do not need an employer to have an HSA.

What if my employer does not offer an HDHP?

You can buy your own HDHP through the marketplace and open an HSA with the linked provider. You will not receive employer contributions, but you can contribute your own money and deduct it on your taxes.

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

If your employer offers only one HDHP and one HSA provider, yes. If they offer multiple options, you can choose. You cannot use a different provider than the one linked to your plan without switching plans first.

Can I open an HSA after my health plan starts?

Yes, but there is usually a deadline — typically 60 days after your plan starts. If you miss it, you can open an HSA when you renew or switch plans the following year. Check with your insurer or broker for the exact deadline.

What if I want to close my HSA?

You can close an HSA at any time. You withdraw all the money (which may trigger taxes and penalties if you use it for non-medical expenses), and the provider closes the account. You can also leave the account open and inactive if you want to keep the money for future medical expenses in retirement.
