You need a may have access to health plan first, then you open the account at a bank or financial institution

A Health Savings Account (HSA) is a savings account that holds money specifically for medical expenses, but you cannot open one without first enrolling in a may have access to health plan — usually a high-deductible health plan (HDHP). The plan comes first. Once you have that plan in place, you choose a bank, credit union, or investment company to hold your HSA, fill out an enrollment form, and fund the account. The whole process typically takes one to two weeks from start to finish.

The reason for this order matters: the IRS only allows you to contribute to an HSA if you are covered by an HDHP and have no other health coverage that would disqualify you. Your health plan provider will give you documentation proving you have an HDHP — you will need this when you open the account.

Key Takeaways

  • You must be enrolled in a high-deductible health plan (HDHP) before opening an HSA; the plan is the gateway to the account.
  • You choose where to open your HSA — a bank, credit union, or investment company — and different institutions offer different features and fees.
  • You will need proof of your HDHP coverage, your Social Security number, and a way to fund the account (paycheck deduction, bank transfer, or check).
  • Contribution limits change each year and depend on whether your plan covers only you or your family; your employer or the IRS website will have the current year's limits.
  • You can change HSA providers later without losing the money already in the account, though some accounts charge fees for transfers.

Confirm you have an HDHP and gather your documents

Before you contact any bank or financial institution, verify that your health plan qualifies. Your employer's benefits materials or your insurance company's website will state whether your plan is an HDHP. If you bought your plan through the health insurance marketplace (Healthcare.gov or your state's equivalent), the plan details will say "high-deductible health plan" or "HDHP" in the coverage information.

Once you confirm you have an HDHP, collect the documents you will need to open the account. You will need your Social Security number, a government-issued ID, proof of your HDHP coverage (your insurance card or a letter from your employer's benefits department), and information about how you want to fund the account. If your employer offers payroll deduction for HSA contributions, you can set that up through your employer's benefits system instead of opening the account yourself — ask your HR or benefits department whether this option is available.

Choose where to open your HSA

You have three main types of institutions to choose from: banks, credit unions, and investment companies. Banks and credit unions typically offer HSA accounts that work like savings accounts — your money sits in a low-interest savings vehicle and you can withdraw it whenever you need it for medical expenses. Investment companies let you invest some or all of your HSA balance in mutual funds or other investments, which means your money can grow but also carries risk.

Compare accounts on a few practical points: monthly or annual fees (some accounts charge $2 to $5 per month, others charge nothing), whether there is a minimum balance requirement, what the interest rate is if you keep money in savings, and whether the institution offers a debit card for medical expenses. If you plan to use your HSA as a long-term savings account rather than spending it when ready, an investment option may make sense. If you want simplicity and quick access to your money, a basic savings account at a bank or credit union is usually the better choice.

Complete the enrollment form and provide proof of coverage

Once you have chosen an institution, you will fill out an HSA enrollment form — either online, by mail, or in person depending on where you are opening the account. The form asks for your name, address, Social Security number, date of birth, and information about your HDHP. You will also declare that you meet the IRS requirements: you are covered by an HDHP, you have no other health coverage that disqualifies you (such as Medicare or a spouse's non-HDHP plan), and you are not claimed as a dependent on someone else's tax return.

The institution will ask you to provide proof of your HDHP coverage. This is usually your insurance card, a benefits summary from your employer, or a letter from your insurance company stating that your plan is an HDHP. Some institutions accept this documentation electronically; others ask you to mail or fax it. Ask the institution what form of proof they accept before you submit your process, so you do not have to resubmit.

Fund your account through payroll or bank transfer

Once your account is open, you need to put money into it. If your employer offers HSA contributions through payroll, you can authorize a deduction from your paycheck — this is often the easiest route because the money comes out before taxes, which reduces your taxable income. You set the amount you want deducted each pay period, up to the annual limit set by the IRS (the limit varies by year and by whether your plan covers only you or your family).

If your employer does not offer payroll deduction, you can fund the account yourself through a bank transfer or by mailing a check. Log into your HSA account online or call the institution and request the routing and account number, then transfer money from your personal bank account. You can also ask your employer's payroll department to send your HSA contributions directly to the account if you provide them with the account details — some employers will do this even if they do not have a formal payroll deduction program set up.

Keep track of how much you contribute during the year. The IRS sets annual limits, and if you contribute more than the limit, you will owe taxes and penalties on the excess. Your HSA provider will send you a statement at the end of the year showing your contributions, so you can verify the total matches what you reported on your taxes.

Set up a debit card or payment method for medical expenses

Many HSA accounts come with a debit card that you can use to pay for medical expenses directly. If your account includes a card, the institution will mail it to you once the account is funded. You can use it at pharmacies, doctors' offices, hospitals, and other medical providers that accept debit cards.

If your account does not include a debit card, you can still withdraw money through online transfers, ATM withdrawals, or checks. Keep receipts for all medical expenses you pay with HSA money, because the IRS requires you to show that the money was spent on may have access to medical expenses if you are ever audited. may have access to expenses include doctor visits, prescriptions, dental work, vision care, and many other health-related costs — but not health insurance premiums (with a few exceptions) or over-the-counter items like vitamins.

Review your account annually and understand contribution limits

The IRS changes HSA contribution limits each year to account for inflation. For 2024, the limits are different for self-only coverage versus family coverage, and they vary slightly from year to year. Your HSA provider will send you information about the current year's limit, and you can also find it on the IRS website or through your employer's benefits materials.

Once a year, usually during your employer's open enrollment period or when your health plan renews, review whether your HSA is still the right choice. If you change to a non-HDHP plan, you can no longer contribute to your HSA, but you can keep the account and spend down the balance on medical expenses. If you switch to a different HDHP, you can continue contributing to the same HSA account or move the money to a new account with a different provider — this is called a trustee-to-trustee transfer and does not count as a withdrawal.

Frequently Asked Questions

Can my employer set up an HSA for me, or do I have to open one myself?

Many employers offer HSA accounts through a payroll system, in which case they handle the setup and you just authorize contributions from your paycheck. If your employer does not offer this, you open the account yourself at a bank or financial institution. Either way, you control the account and the money in it.

What happens to my HSA if I change jobs or leave my employer?

Your HSA stays with you — it is your account, not your employer's. You can keep contributing to it if you remain enrolled in an HDHP through your new employer or through the marketplace. If you lose HDHP coverage, you can no longer contribute, but you keep the money and can spend it on medical expenses anytime.

Can I open an HSA if I am self-employed or have a one-person business?

Yes, as long as you are enrolled in an HDHP. You open the account the same way an employee would, and you can contribute up to the annual limit. You will report your contributions on your tax return when you file.

Do I have to use my HSA money every year, or can I save it?

You can save it indefinitely. Unlike a flexible spending account (FSA), which has a "use it or lose it" rule, an HSA rolls over year to year. Money you do not spend stays in the account and grows. This is one reason an HSA can be useful as a long-term savings tool for future medical expenses.

What if I make a mistake on my HSA enrollment form?

Contact your HSA provider as soon as you notice the error. Most institutions can correct information like your address or phone number when ready. If the error involves your coverage status or contribution amount, tell your provider right away so they can help you fix it before tax time.
