You open an HSA through a bank, credit union, or insurance company that offers them

An HSA is not something you get from your employer or the government — you open one yourself, the same way you open a checking account. The account holder (you) controls the money, not your employer or your health plan. You can open an HSA at most banks, many credit unions, and some insurance companies. Some employers offer HSA accounts through payroll, which makes contributions easier but does not change who owns the account or where the money goes.

The catch is that you must be enrolled in a high-deductible health plan (HDHP) to open or contribute to an HSA. If you do not have an HDHP, you cannot use an HSA, even if a bank will let you open the account. The IRS enforces this rule, and contributions made while you are not covered by an HDHP trigger penalties and taxes.

You can open an HSA at any time during the year, but contributions for that year must be made by the tax filing deadline (usually April 15 of the following year). If you enroll in an HDHP mid-year, you can still open an HSA and contribute a prorated amount for the months you were covered.

Key Takeaways

  • You must be enrolled in a high-deductible health plan to open an HSA; without one, you cannot contribute or use the account.
  • Banks, credit unions, and insurance companies all offer HSAs, and you choose which one based on fees, investment options, and ease of use.
  • Your employer may offer an HSA through payroll, which simplifies contributions but does not change who owns the account or controls the money.
  • Contributions for a given year must be made by the tax filing deadline, even if you open the account after the calendar year ends.
  • You can move your HSA to a different provider at any time without penalty, and the money stays yours regardless of where you bank it.

Opening an HSA at a bank or credit union

Most major banks and credit unions offer HSAs. You can walk into a branch, call, or go online to open one. The process is similar to opening a savings account: you provide your name, Social Security number, address, and proof of HDHP coverage. Some banks ask for a copy of your insurance card or a letter from your health plan confirming your HDHP status.

Banks differ in what they charge. Some have no monthly fee; others charge $2 to $5 per month. Some charge per transaction or per investment trade if you want to invest the money rather than keep it in a savings account. Before you open, compare the fee structure of at least two or three institutions. A $3 monthly fee costs $36 per year, which matters if you are only contributing $500 or $1,000 total.

Ask whether the bank offers investment options. Some HSAs sit in a savings account earning minimal interest. Others let you invest in mutual funds or index funds once you reach a minimum balance (often $1,000 to $2,500). If you plan to keep the HSA long-term and let it grow, investment options matter. If you plan to spend the money within a year or two, a simple savings account is fine.

Opening an HSA through your employer

Many employers offer HSAs as part of their benefits package, usually through a third-party administrator like HealthEquity, Fidelity, or Lively. If your employer offers one, you can enroll during open enrollment or when you first become may be able to access for the HDHP. Contributions are taken directly from your paycheck before taxes, which reduces your taxable income for the year.

Employer-sponsored HSAs are convenient because payroll deductions are automatic and you do not have to find a bank on your own. However, you still own the account. If you leave the job, the money stays in your HSA — it does not go back to your employer. You can keep the account open, transfer it to a different provider, or leave it where it is.

Some employers limit you to one HSA provider. If the provider charges high fees or does not offer investment options you want, you can open a second HSA at a bank or credit union and transfer money between them. You can only have one HSA at a time (the IRS counts all accounts together), but you can move money between providers without penalty.

Opening an HSA through your insurance company

Some health insurers offer HSAs directly to their members. If your HDHP is through a major insurer like UnitedHealthcare, Aetna, or Anthem, check whether they offer an HSA. The advantage is that everything is in one place: your health plan, your HSA, and your claims are all managed by the same company.

The disadvantage is that you may have fewer choices. If the insurer's HSA has high fees or limited investment options, you cannot easily switch without leaving the health plan. Before you enroll in an HDHP through an insurer, ask about their HSA offering and compare it to what you could get at a bank or credit union.

What you need to open an HSA

You will need proof that you are enrolled in an HDHP. This is usually your insurance card or a letter from your health plan. Some providers ask for your plan's deductible amount and out-of-pocket maximum to verify it meets IRS requirements. Have these numbers ready when you apply.

You will also need a Social Security number, a government-issued ID, and a current address. If you are opening the account online, you may be able to upload a photo of your insurance card. If you are opening in person or by phone, have the information ready to read aloud.

Some banks require a minimum opening deposit, usually $0 to $25. A few require a minimum balance to avoid monthly fees. Read the account agreement before you open to understand what you are committing to.

Moving an HSA to a different provider

You can move your HSA from one bank or provider to another at any time. This is called a trustee-to-trustee transfer. The money moves directly from the old account to the new one, and you do not pay taxes or penalties. You do not even have to report it on your tax return.

Contact the new provider and ask them to initiate the transfer. They will handle the paperwork with your old provider. The process usually takes one to two weeks. During that time, your money is in transit and you cannot spend it, so plan accordingly.

You can also do a rollover, where you withdraw the money yourself and deposit it into a new HSA within 60 days. This is riskier because if you miss the 60-day window, the withdrawal counts as taxable income and you owe a 20% penalty. Trustee-to-trustee transfers are safer and simpler.

Frequently Asked Questions

Can I open an HSA if my employer does not offer one?

Yes. You can open an HSA at any bank, credit union, or insurance company that offers them, as long as you are enrolled in an HDHP. You will not get the payroll deduction benefit, but the account works the same way. You contribute with after-tax dollars and then deduct the contribution on your tax return.

What if I change jobs or lose my HDHP coverage?

Your HSA stays yours. The money does not disappear and you do not lose access to it. However, you cannot make new contributions once you are no longer covered by an HDHP. You can still withdraw money for may have access to medical expenses without penalty. If you withdraw for non-medical reasons, you owe income tax plus a 20% penalty.

Can I have more than one HSA?

No. The IRS treats all your HSAs as one account for contribution limits. If you have two HSAs and contribute to both, you may exceed the annual limit and owe taxes and penalties. If you open a second account by mistake, close one immediately or transfer the balance to consolidate them.

Do I have to use my employer's HSA, or can I open my own?

You can do either or both. If your employer offers an HSA, you can use it for the payroll deduction benefit. You can also open a separate HSA at a bank if the employer's plan has high fees or poor investment options. Just remember that your total contributions across all accounts cannot exceed the annual IRS limit.

What happens to my HSA if I retire or turn 65?

Your HSA does not close. After age 65, you can withdraw money for any reason without the 20% penalty, though you still owe income tax on non-medical withdrawals. If you are on Medicare, you cannot make new contributions, but you can keep the account and spend it down or let it grow.
