Opening a Health Savings Account: Step-by-Step

By Cassandra Finch · Education and Health Savings Writer

How to open a health savings account

You open an HSA through a bank, credit union, or investment firm — not through your employer or the government, even if your employer offers one. The process takes 15 to 30 minutes and requires proof of enrollment in a high-deductible health plan (HDHP), your Social Security number, and a valid ID. You can open an account online, by phone, or in person at most financial institutions.

The first step is confirming you meet the HSA rules: you must be covered by an HDHP, have no other health insurance except what the IRS allows alongside an HSA, and not be claimed as a dependent on someone else's tax return. Once you confirm those conditions, you choose a provider and complete their account application. The provider will ask for your HDHP plan details — your insurance company name, plan name, and deductible amount — so have your insurance card or plan documents ready.

Key Takeaways

  • You open an HSA directly with a bank, credit union, or investment firm, not through your employer, even if your employer mentions HSAs.
  • You must be enrolled in a high-deductible health plan and have no other health insurance (with limited exceptions) to open an account.
  • The application requires your Social Security number, valid ID, and proof of HDHP enrollment — your insurance card or plan documents.
  • You can contribute up to $4,150 for individual coverage or $8,300 for family coverage in 2024, though these amounts change yearly.
  • Once your account is open, you can fund it immediately and begin using the debit card or reimbursement method to pay for medical expenses.

Choosing between banks, credit unions, and investment firms

Different providers offer different features, and the right choice depends on whether you plan to spend the money soon or invest it for later. Banks and credit unions typically offer HSA accounts with a debit card, check-writing, and low or no fees — good if you expect to use the money within a year or two. Investment firms like Fidelity, Vanguard, and Charles Schwab let you invest HSA funds in mutual funds and stocks, which can grow tax-free over decades, but usually charge a monthly fee ($2 to $5) and require a minimum balance before investing.

Compare three things before you choose: the monthly or annual fee (many banks charge nothing; investment firms often charge $2 to $5 per month), the debit card availability (not all providers offer one), and the investment options (if you want to invest). Some employers partner with a specific HSA provider and may offer matching contributions or fee waivers, so check your benefits materials first — you are not required to use your employer's provider, but doing so may save money.

What documents you need to open an account

Gather these items before you start the application: your Social Security number, a valid government-issued ID (driver's license or passport), and proof that you are enrolled in an HDHP. Proof of enrollment can be your insurance card, a letter from your insurance company, or a screenshot of your plan details from your insurer's website. If your employer offers the HSA, you may have received a summary document listing the plan name and deductible — that works too.

The provider will ask for your HDHP plan name, your insurance company name, and your deductible amount. If you do not have this information handy, call your insurance company or log into your online account — most insurers show the deductible on the plan summary page. You will also need to provide your address and contact information, and choose how you want to fund the account (payroll deduction through your employer, bank transfer, or check).

Funding your HSA after opening it

Once your account is open, you can fund it in three ways: through payroll deduction (if your employer offers it), by transferring money from your bank account, or by mailing a check. Payroll deduction is the most common route — your employer deducts a set amount from each paycheck and deposits it directly into your HSA. This happens automatically once you enroll, and the money is not subject to income tax or payroll tax, which saves you roughly 25 to 30 percent compared to contributing after-tax dollars.

If you do not have payroll deduction available, you can transfer money from your checking or savings account to your HSA using your account number and routing number. You can also mail a check to the address your provider gives you. The IRS sets annual contribution limits — $4,150 for individual coverage and $8,300 for family coverage in 2024 — and these limits change each year. You can contribute the full year's amount at once or spread it across the year; the tax benefit is the same either way.

Using your HSA to pay for medical expenses

Most HSA providers issue a debit card that you can use at pharmacies, doctor's offices, and hospitals to pay for may have access to medical expenses directly from your account. may have access to expenses include copays, coinsurance, deductibles, prescription drugs, dental work, vision care, and many other health-related costs — the IRS publishes a full list on its website. You can also pay out of pocket and then request reimbursement from your HSA by submitting receipts and a reimbursement form.

Keep your receipts and medical bills for at least three years in case the IRS asks for proof that your withdrawals were for may have access to expenses. If you withdraw money for a non-may have access to expense before age 65, you owe income tax on that amount plus a 20 percent penalty. After age 65, you can withdraw money for any reason without the penalty, though non-medical withdrawals are still subject to income tax.

HSA contribution deadlines and tax reporting

You can open an HSA and make contributions for a given tax year until the tax filing deadline — usually April 15 of the following year. For example, you can open an account in January 2025 and contribute to it through April 15, 2025, and that contribution counts toward your 2024 tax year. If you enroll in an HDHP mid-year, you can still contribute a prorated amount for that year, though some providers make this easier than others.

Your HSA provider will send you a Form 5498-SA each year showing how much you contributed and how much you withdrew. You will use this form when you file your taxes to report your HSA activity. If you contributed through payroll deduction, your employer already withheld the tax benefit, so you do not need to do anything else. If you contributed after-tax dollars, you will deduct those contributions on your tax return using Form 8889.

Moving or closing an HSA

You can move your HSA to a different provider at any time without penalty — this is called a trustee-to-trustee transfer. Contact your new provider and they will handle the transfer directly with your old provider; you do not touch the money. This usually takes one to two weeks. You can also withdraw the money yourself and deposit it into a new HSA within 60 days, though this is riskier because you are responsible for meeting the deadline.

If you lose your HDHP coverage — because you switched to a different health plan, enrolled in Medicare, or gained other health insurance — you can no longer contribute to your HSA, but you can keep the account and withdraw money for may have access to medical expenses. The money in your HSA is yours to keep even if you change jobs or retire. If you close the account and withdraw all the money, you owe income tax and a 20 percent penalty on any non-may have access to withdrawals.

Frequently Asked Questions

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

Yes. You can open an HSA on your own as long as you are enrolled in an HDHP, whether through your employer, the marketplace, or a private plan. You will not have payroll deduction, so you will fund it by bank transfer or check, but the tax benefits are identical.

What happens if I open an HSA but then switch to a different health plan?

You can no longer contribute to the HSA once you lose HDHP coverage, but the money already in the account stays there and you can withdraw it for may have access to medical expenses anytime. If you later re-enroll in an HDHP, you can resume contributing to the same account or open a new one.

Do I have to invest my HSA money, or can I just leave it in the account?

You do not have to invest it. Most people leave their HSA in a cash account earning little or no interest, especially if they plan to use the money within a few years. Investing is optional and makes sense only if you have enough money to cover your near-term medical expenses and want to grow the rest for retirement.

Can I open an HSA if I am on Medicare?

No. Once you enroll in Medicare, you are no longer may be able to access to contribute to an HSA because Medicare is not an HDHP. You can keep an existing HSA and withdraw money from it for may have access to expenses, but you cannot make new contributions.

What if I make a mistake on my HSA application?

Contact your provider as soon as you notice the error — most can correct basic information like your address or phone number immediately. If you provided incorrect HDHP details, the provider may ask you to submit updated proof of enrollment. Errors do not usually delay your account opening or funding.
