Opening an HSA: The Steps From Choosing a Provider to Making Your First Deposit

You need three things to open an HSA: a high-deductible health plan, a provider that holds HSA accounts, and money to deposit

An HSA starts with your health insurance. You must be enrolled in a high-deductible health plan (HDHP) — a specific category of coverage with a minimum deductible set by the IRS each year. For 2024, that minimum is $1,600 for self-only coverage and $3,200 for family coverage. Once you have that plan, you can open an HSA through a bank, credit union, or investment firm. The account itself is separate from your insurance; your insurer does not run it. You then fund it with your own money, your employer's contribution, or both.

The order matters. You cannot open an HSA before you have HDHP coverage, and you cannot contribute to an HSA in a month when you are not covered by an HDHP. If you switch to a different health plan mid-year, your HSA stays open, but you stop being able to add money to it that year.

Key Takeaways

• You must be enrolled in an HDHP before you can open an HSA; the account cannot exist without that coverage.
• Your employer may offer an HSA through payroll, which is the fastest route because contributions come directly from your paycheck before taxes.
• If your employer does not offer one, you can open an HSA independently through a bank or investment provider, but you will need to track and claim the tax deduction yourself.
• The IRS sets annual contribution limits ($4,150 for self-only coverage in 2024, $8,300 for family coverage), and you can only contribute for months when you held HDHP coverage.
• You can start using HSA money for medical expenses when ready after you open the account, even if you have not finished funding it.

Confirm your health plan qualifies as an HDHP

Before you contact any HSA provider, check that your health insurance actually meets the HDHP definition. Your insurance company or your employer's benefits team can tell you whether your plan qualifies. The IRS publishes the minimum deductible and out-of-pocket limits each year on its website; for 2024, a self-only HDHP must have a deductible of at least $1,600 and maximum out-of-pocket costs of $3,300. Family plans must have a deductible of at least $3,200 and maximum out-of-pocket costs of $6,650.

Some plans look like they have a high deductible but do not count as HDHPs because they cover certain services before the deductible is met — for example, preventive care or primary care visits. The IRS allows this for preventive services, but not for other care. If you are unsure, ask your insurer directly: "Is this plan an IRS-may have access to high-deductible health plan?" They will know the answer.

Choose between employer-sponsored and independent HSAs

If your employer offers an HSA, that is usually the simplest path. Your employer will have already chosen a provider — often a bank or investment firm — and set up payroll deductions. You fill out enrollment forms (usually online during open enrollment or when you first become HDHP-may be able to access), and contributions come straight from your paycheck before federal income tax is withheld. This saves you the step of claiming a tax deduction later.

If your employer does not offer an HSA, or if you are self-employed, you open one independently. You will need to choose a provider yourself. Banks, credit unions, and investment firms all offer HSAs. Some charge monthly maintenance fees; others waive fees if you maintain a minimum balance. Some let you invest HSA money in stocks and mutual funds; others keep it in a savings account. Compare a few providers on their fee structure and investment options before you decide.

An independent HSA requires more paperwork. You will contribute money out of your own pocket and then claim the tax deduction on your tax return (Form 1040, Schedule 1). You are responsible for tracking how much you contributed and making sure you do not exceed the annual limit.

Gather the documents and information you will need

To open an HSA, you will need your Social Security number, proof of HDHP coverage, and a way to fund the account. Proof of coverage usually means your insurance card or a letter from your insurer or employer stating that you are enrolled in an HDHP. Some providers ask for the plan name and deductible amount; others just need confirmation that the plan qualifies.

If you are opening an employer-sponsored HSA, your employer's benefits team will tell you what documents to submit. If you are opening an independent HSA, the provider's website will list what they need. Most can be done entirely online, and many providers let you upload documents through their process portal.

You will also need to decide how you want to fund the account. If it is employer-sponsored, you choose a payroll deduction amount. If it is independent, you can fund it by bank transfer, check, or automatic monthly deposits. Some providers let you set up recurring transfers so you do not have to remember to fund it each month.

Complete the process and fund your account

For an employer-sponsored HSA, the process is usually part of your benefits enrollment. You log into your employer's benefits portal, select the HSA option, choose your contribution amount, and confirm. The first deduction typically appears in your next paycheck. Some employers let you start mid-year if you become HDHP-may be able to access after open enrollment.

For an independent HSA, you go to the provider's website, click to open an account, and fill out an process. You will enter your personal information, Social Security number, and HDHP details. The provider will ask you to verify your identity — usually by answering security questions or uploading a photo ID. Once approved, you can fund the account. Most providers let you transfer money from your bank account when ready; some require you to wait a few business days for the account to fully set up.

You do not have to fund the entire year's contribution at once. You can deposit money monthly, quarterly, or in a lump sum. The only requirement is that you do not exceed the annual limit by the end of the calendar year.

Understand the contribution limits for your situation

The IRS sets annual contribution limits, and they change each year. For 2024, you can contribute up to $4,150 if you have self-only HDHP coverage, or $8,300 if you have family coverage. If you are 55 or older, you can contribute an additional $1,000 per year (called a catch-up contribution).

The limit applies to all your HSA contributions combined — from your employer, from you, and from anyone else who contributes on your behalf. If your employer contributes $2,000 and you contribute $1,500, that is $3,500 total, and you have $650 of your limit remaining for the year.

You can only contribute for months when you held HDHP coverage. If you switched to a different health plan in July, you can only contribute for January through June. If you contributed too much, you will owe taxes and a 20 percent penalty on the excess amount, so it is worth tracking carefully.

Start using your HSA for medical expenses right away

Once your account is open, you can use the money for may have access to medical expenses when ready. You do not have to wait until the account is fully funded. Most HSAs come with a debit card that works like a regular bank card at pharmacies, doctors' offices, and hospitals. Some providers mail the card; others let you order it through the app. You can also request a check or transfer money to your bank account to pay for medical expenses out of pocket, then reimburse yourself from the HSA later.

Keep receipts for any medical expenses you pay with HSA money. The IRS does not require you to submit them when you withdraw, but you must be able to prove the expense was medical if you are ever audited. may have access to expenses include doctor visits, prescriptions, dental work, vision care, mental health treatment, and many other health-related costs. Over-the-counter medications are covered only if you have a prescription.

Frequently Asked Questions

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

Yes. You can open an HSA independently through a bank, credit union, or investment firm as long as you are enrolled in an HDHP. You will need to track your contributions and claim the tax deduction on your tax return yourself. The provider will send you a Form 5498-SA each year showing what you contributed, which you use when filing taxes.

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

Your HSA is yours to keep. If you had an employer-sponsored HSA, you can roll it to an independent HSA at another provider, or leave it where it is and continue to manage it on your own. You just stop making contributions through payroll. The money stays in the account and grows tax-free as long as you use it for medical expenses.

Can I contribute to an HSA if I am on Medicare?

No. Once you enroll in Medicare, you are no longer covered by an HDHP, so you cannot make new contributions. You can still withdraw money from an existing HSA for medical expenses, including Medicare premiums and out-of-pocket costs. If you withdraw for non-medical reasons after age 65, you owe income tax but not the 20 percent penalty.

How long does it take to open an HSA?

Employer-sponsored HSAs usually set up within one to two pay periods after you enroll. Independent HSAs can be opened in a few minutes online, though the provider may take one to three business days to verify your identity and set up the account. You can start using the account as soon as it is active.

Do I have to invest my HSA money, or can I just keep it in savings?

You can do either. Some HSA providers offer only a savings account option; others let you choose between savings and investment accounts. If you invest, your money can grow faster, but you also take on investment risk. Many people keep a portion in savings for near-term medical expenses and invest the rest for long-term growth.
