Opening an HSA Account: Step-by-Step Instructions

How to open an HSA account

You open an HSA through a bank, credit union, or insurance company that offers HSA accounts — not through your employer or the government. Your employer may offer one through payroll, which is the fastest route, but you can also open one independently at any financial institution that administers HSAs. The account itself is separate from your health insurance; the HSA is just a savings account with tax advantages, and you control it even if you leave your job.

The real requirement before you open anything is that you must be enrolled in a high-deductible health plan (HDHP). If you have traditional health insurance with a low deductible, you cannot open an HSA. If you have Medicare, Medicaid, or TRICARE, you are not may be able to access. Once you confirm you have an HDHP, you can move forward.

Key Takeaways

You must be enrolled in a high-deductible health plan before opening an HSA; traditional insurance plans do not may have access to.
The easiest path is through your employer's payroll system if they offer HSAs, because contributions come directly from your paycheck before taxes.
You can also open an HSA independently at a bank, credit union, or insurance company, and you keep the account even if you change jobs.
You will need your Social Security number, proof of HDHP enrollment, and a small initial deposit, which varies by institution.
Once opened, you can contribute up to the annual limit set by the IRS, which changes each year and depends on whether your plan covers one person or a family.

Opening an HSA through your employer

If your employer offers an HSA, this is usually the simplest route. During your company's open enrollment period or when you first become may be able to access, you will see HSA options in your benefits materials. You choose the HSA provider your employer has partnered with — you do not get to pick any bank you want; your employer has already selected one or two options.

You complete an enrollment form (usually online) that asks for your name, Social Security number, date of birth, and confirmation that you are enrolled in an HDHP. You decide how much to contribute per paycheck. Your employer then deducts that amount from your gross pay before taxes are calculated, which means you save money on federal income tax, Social Security tax, and Medicare tax on those contributions.

The account opens within a few days to a week. You receive a debit card or checkbook to spend from the account, and you can log into an online portal to see your balance and transaction history. Money you do not spend in a calendar year rolls over to the next year — there is no "use it or lose it" deadline like some other workplace benefits.

Opening an HSA on your own

If your employer does not offer an HSA, or if you are self-employed or unemployed, you can open one independently. Start by searching for "HSA accounts" at banks and credit unions in your area, or at national providers like Fidelity, Lively, or HealthEquity. Each institution has different fees, investment options, and minimum deposits, so comparing a few is worth the time.

You will need to provide your Social Security number, proof that you are enrolled in an HDHP, and a small initial deposit — usually between $0 and $500 depending on the institution. Some banks ask for a copy of your insurance card or a letter from your insurance company confirming your HDHP status. You can usually complete the application online in 10 to 15 minutes.

Once approved, you fund the account by transferring money from your checking account or by setting up automatic monthly transfers. Unlike employer accounts, you do not get automatic payroll deduction, so you have to manage contributions yourself. You still get the same tax advantages — money you contribute is not subject to federal income tax — but you have to claim the deduction on your tax return.

What documents you will need

The core documents are your Social Security number and proof of HDHP enrollment. For proof of enrollment, most institutions accept a copy of your insurance card, a letter from your insurance company, or your enrollment confirmation from your employer's benefits system. If you are opening through your employer, they usually handle the verification themselves.

If you are opening independently, call the HSA provider before you apply and ask exactly what they need. Some accept a photo of your insurance card; others want a formal letter. Having this ready before you start the application saves time. You will also need a valid government ID (driver's license or passport) and a current address.

Annual contribution limits and timing

The IRS sets a maximum amount you can contribute to an HSA each year. The limit changes annually and depends on whether your HDHP covers only you or covers your family. For 2024, the limit is $4,150 for individual coverage and $8,300 for family coverage; these amounts increase most years. If you are 55 or older, you can contribute an additional $1,000 per year.

You can contribute at any time during the year, but contributions for a specific tax year must be made by April 15 of the following year (the tax filing deadline). If you open an HSA partway through the year, you can still contribute the full annual amount for that year, as long as you make the contribution by the April 15 deadline. If you change jobs or lose HDHP coverage, you stop being able to contribute, but money already in the account stays there and continues to grow tax-free.

Fees and account maintenance

HSA accounts come with different fee structures depending on the provider. Common fees include a monthly maintenance fee (typically $2 to $5), a per-transaction fee (25 cents to $1 per withdrawal or transfer), or an investment fee if you invest the money rather than keep it in cash. Some institutions waive fees if you maintain a minimum balance, usually $1,000 to $2,500.

When comparing providers, add up the total annual cost for your expected usage. If you plan to spend from the account every month, per-transaction fees matter more. If you plan to save the money and invest it, investment fees matter more. Many employers choose providers with low or no fees, so if you are opening through payroll, you may not have to worry about this. If you are opening independently, spending 20 minutes comparing three providers can save you $50 to $100 per year.

What happens after you open the account

Once your account is open and funded, you can spend the money on may have access to medical expenses — doctor visits, prescriptions, dental work, vision care, and many other health-related costs. You receive a debit card or checkbook to pay directly, or you can pay out of pocket and reimburse yourself from the account later. Keep receipts for all medical expenses you pay from the HSA, because the IRS can audit these transactions.

You do not have to spend the money in the year you contribute it. Money rolls over indefinitely, and you can let it grow and invest it if you want. This makes HSAs different from flexible spending accounts (FSAs), which have a "use it or lose it" rule. Some people use their HSA as a retirement account, contributing the maximum each year and only spending from it after age 65, when withdrawals for non-medical expenses become taxable but penalty-free.

Frequently Asked Questions

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. If you already have an HSA, the money stays in the account and you can spend it on medical expenses, but you cannot add new contributions. If you are approaching 65 and want to maximize your HSA, you can contribute for the months before you turn 65.

What if my employer offers an HSA but I want to open one somewhere else?

You can open a second HSA at another institution, but your total contributions across all accounts cannot exceed the annual IRS limit. If your employer contributes $2,000 per year, you can only contribute $2,150 more (for individual coverage in 2024). Most people stick with their employer's HSA because payroll deduction is simpler and employers often choose low-fee providers.

How long does it take to open an HSA?

Through an employer, the account usually opens within a few days to a week after you enroll. Opening independently takes about the same time — you complete the application online, and the account is ready to use within three to five business days. You can start contributing immediately, though the first deposit may take one to two business days to clear.

Can I move my HSA to a different bank?

Yes. You can roll over money from one HSA to another without penalty, similar to rolling over a retirement account. Contact the new institution and ask for their rollover process. You typically have 60 days to complete the transfer. If you leave your job, you can move your employer's HSA to an independent account at any bank.

What if I do not have an HDHP yet?

You cannot open an HSA until you are enrolled in an HDHP. If you have traditional insurance, you would need to switch plans during your employer's open enrollment period or during a may have access to life event (job change, loss of coverage, marriage, birth). Once you enroll in an HDHP, you can open an HSA immediately.
