You need three things to open an HSA: a may have access to high-deductible health plan, a bank or financial institution that offers HSA accounts, and proof of your coverage

Opening an HSA is straightforward because you do not need permission from your employer or the government. You choose the bank, you choose how much to contribute each year (within legal limits), and you control the money. The process takes about 15 minutes online or over the phone, though some banks require you to mail in a form if you are self-employed or do not have an employer plan.

The real work is not opening the account—it is making sure you actually have a may have access to plan. An HSA only works with a High-Deductible Health Plan (HDHP), which is a specific type of health insurance with a deductible of at least $1,550 for individual coverage or $3,100 for family coverage in 2024. If your plan does not meet those thresholds, you cannot open an HSA, no matter how much you want to. Your insurance company or employer will tell you whether your plan qualifies.

Once you confirm you have an HDHP, you can open an account at any bank, credit union, or investment firm that offers HSAs. Some employers offer HSAs through a specific provider, but you are not required to use theirs—you can open one elsewhere and transfer money in later if you prefer.

Key Takeaways

  • You must have a High-Deductible Health Plan with a deductible of at least $1,550 (individual) or $3,100 (family) in 2024 to open an HSA.
  • You can open an HSA at any bank, credit union, or investment company that offers them—you are not locked into your employer's choice.
  • The account setup takes 15 minutes online, but you will need proof of your HDHP coverage, usually a copy of your insurance card or plan documents.
  • You can contribute up to $4,150 for individual coverage or $8,300 for family coverage in 2024, and you can change your contribution amount once per year or when your coverage changes.
  • Money you do not spend stays in the account forever and grows tax-free if you invest it.

Where to open an HSA account

The major banks that offer HSAs include Fidelity, Lively, HealthEquity, Optum Bank, and Aetna Bank. Credit unions and smaller regional banks also offer them, though you may need to ask. Each provider charges different fees (some charge nothing, some charge $2 to $5 per month), offers different investment options if you want to invest the money rather than keep it in cash, and has different customer service channels.

If your employer offers an HSA through a payroll deduction, you will likely use their chosen provider because the money comes straight from your paycheck before taxes. But you can still open a separate HSA at another bank and transfer money between them. Some people do this to get better investment options or lower fees.

Before you choose a provider, check whether they charge monthly maintenance fees, what the minimum balance is (some require $0, some require $25 or more), and whether they offer investment options if you want to invest rather than hold cash. If you plan to use the account only for when ready medical expenses, a low-fee cash account at a bank is fine. If you plan to save for years and invest the money, look for a provider with low investment fees.

What documents you need to open an account

You will need proof that you have an HDHP. This is usually your insurance card, a letter from your employer confirming your plan type, or a screenshot of your plan details from your insurance company's website. Some providers ask you to upload this document during signup; others just ask you to confirm you have coverage and may ask for proof later if they audit your account.

You will also need a Social Security number or Individual Taxpayer Identification Number (ITIN), a current address, and a valid form of identification. If you are opening the account online, you may need to verify your identity through a third-party service that checks your credit report (this does not affect your credit score). If you are opening by mail or phone, you may need to send a copy of your ID.

If you are self-employed or do not have an employer, some banks require additional documentation showing your income or business structure. Ask the bank before you start the process.

How to fund your HSA

You can fund an HSA three ways: through payroll deduction from your employer, by transferring money from your bank account, or by mailing a check. Payroll deduction is the most common because the money comes out before taxes are calculated, which saves you money when ready. If your employer offers an HSA, ask your HR or payroll department how much you want to contribute each year, and they will deduct it from each paycheck.

If you do not have an employer HSA or want to contribute more, you can transfer money from your checking or savings account to your HSA. This takes one to three business days. You will report this contribution on your tax return (Form 8889) to get the tax deduction. If you do not report it, you will pay taxes on the money twice—once when you earn it and again when you spend it on medical care.

You can contribute up to $4,150 for individual coverage or $8,300 for family coverage in 2024. If you are 55 or older, you can contribute an extra $1,000 per year (called a catch-up contribution). You can change your contribution amount once per year during open enrollment, or when ready if your coverage changes (you switch plans, lose coverage, or gain coverage).

Contribution limits and catch-up contributions

The annual contribution limit changes each year based on inflation. In 2024, the limit is $4,150 for individual coverage and $8,300 for family coverage. These limits explore to all your HSAs combined—if you have two HSA accounts, the total you can contribute across both is still $4,150 or $8,300.

If you turn 55 during the year, you can make a catch-up contribution of $1,000 for that year. This is separate from the main limit. If you are 55 and have individual coverage, you can contribute $4,150 plus $1,000 for a total of $5,150. You can make catch-up contributions every year after you turn 55, even after you retire, as long as you have an HDHP.

If you contribute more than the limit, you will owe taxes and a 20 percent penalty on the excess. The bank or provider does not automatically stop you from over-contributing, so you need to track it yourself. If you realize you over-contributed, you can withdraw the excess and the earnings on it before the tax filing important date (usually April 15) to avoid the penalty.

Setting up automatic contributions and investment options

Most HSA providers let you set up automatic monthly transfers from your bank account. This spreads your annual contribution across the year and makes it easier to remember. You can change or stop automatic transfers anytime, though some banks require you to do this online or by phone rather than email.

Once money is in your HSA, you can leave it in a cash account (earning little or no interest) or invest it in mutual funds, stocks, or other securities offered by your provider. If you invest, the money grows tax-free as long as you spend it on medical expenses. If you withdraw it for non-medical reasons before age 65, you pay taxes and a 20 percent penalty on the earnings (but not the contributions). After age 65, you can withdraw money for any reason without the penalty, though you still pay taxes on earnings if you do not spend it on medical care.

Not all providers offer investment options. If you want to invest, check whether your chosen provider offers mutual funds or brokerage accounts before you open. Some charge fees to invest (like $1 to $3 per trade), while others offer free investing.

Verifying your HDHP coverage and avoiding account closure

After you open your HSA, the provider may contact your insurance company to confirm you have an HDHP. This is called verification and usually happens within 30 days. If the insurance company says you do not have a may have access to plan, the bank will close your account and may ask you to return any tax deductions you claimed.

To avoid this, make sure your insurance card or plan documents clearly show you have an HDHP. If your plan name includes words like "High Deductible" or "HDHP," you are likely fine. If you are unsure, call your insurance company and ask whether your plan qualifies for an HSA. Write down the date and the representative's name in case you need to dispute a closure later.

If your coverage changes during the year—you switch plans, lose coverage, or gain coverage—tell your HSA provider when ready. You can only contribute to an HSA for months when you have HDHP coverage. If you contribute for a month when you do not have coverage, you will owe taxes and a 20 percent penalty on that contribution.

Frequently Asked Questions

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

Yes. You can open an HSA at any bank or financial institution that offers them, as long as you have an HDHP. You will need to contribute the money yourself (not through payroll deduction) and report the contribution on your tax return to claim the deduction. Some self-employed people and people on individual health plans open HSAs this way.

What happens to my HSA if I change jobs?

Your HSA stays yours. The money does not go away, and you do not lose it. You can keep the account open at the same bank, or you can transfer the balance to a new HSA at a different bank. If your new employer offers an HSA, you can use theirs for future contributions and keep your old account for the balance.

Can I use my HSA to pay for my spouse's medical expenses?

Yes, as long as your spouse is covered under your family HDHP or is your tax dependent. You cannot use an HSA to pay for a spouse who has their own separate health insurance plan. If your spouse also has an HDHP, they can open their own HSA and contribute separately.

What if I do not spend all my HSA money in a year?

The money rolls over to the next year forever. Unlike a Flexible Spending Account (FSA), there is no "use it or lose it" rule with an HSA. You can let the balance grow year after year and invest it if you want. This makes HSAs useful for saving for future medical expenses or retirement.

Do I need to submit receipts to my HSA provider when I spend the money?

No. You can spend HSA money on may have access to medical expenses without submitting receipts to the bank. However, you should keep receipts for your own records in case the IRS audits you. The IRS can ask you to prove that the money was spent on medical expenses, and receipts are your proof.
