You need a high-deductible health plan first, then open an HSA with a bank or financial institution

A Health Savings Account is a tax-advantaged savings account, but you cannot open one without first being enrolled in a high-deductible health plan (HDHP). The HDHP is the gateway — your health insurance provider will confirm your plan qualifies, and then you can open an HSA at a bank, credit union, or investment firm. The account itself is separate from your insurance; you choose where to hold it.

The process has three parts: confirm your health plan qualifies, choose where to open the account, and complete the enrollment. Most people finish within a few days, though some employers handle HSA setup automatically during open enrollment.

Key Takeaways

  • You must be enrolled in a high-deductible health plan to open an HSA; plans that do not meet the IRS deductible threshold will not work.
  • You can open an HSA at a bank, credit union, brokerage firm, or through your employer's benefits plan — the choice affects fees and investment options.
  • The IRS sets annual contribution limits, which change each year and depend on whether your coverage is individual or family.
  • You can open an HSA at any time during the year, but contributions for a tax year must be made by the tax filing important date (usually April 15).
  • If you lose HDHP coverage, you can no longer contribute to your HSA, though you keep the money already in it.

Confirm your health plan meets the HDHP definition

The IRS sets specific deductible and out-of-pocket limits that determine whether your plan qualifies. For 2024, an individual plan must have a deductible of at least $1,600 and out-of-pocket maximum of no more than $3,200. A family plan must have a deductible of at least $3,200 and out-of-pocket maximum of no more than $6,400. These numbers change annually.

Your health insurance company will tell you whether your plan qualifies — check your plan documents or call the customer service number on your insurance card. If you are shopping for a plan, insurers label HDHP-may be able to access plans clearly in their plan comparison tools. You cannot have other health coverage (except specific exceptions like dental or vision insurance) while contributing to an HSA.

Choose where to open your account

You have four main routes: your employer's benefits plan, a bank, a credit union, or an investment firm. Each has different costs and features.

Through your employer: Many employers offer HSA accounts as part of their benefits package, sometimes with matching contributions or subsidized fees. This is often the simplest route because payroll deductions are automatic and the employer has already vetted the provider. Ask your HR or benefits department whether they offer an HSA and which financial institution holds the accounts.

At a bank or credit union: You can open an HSA directly with any bank or credit union that offers them. Banks typically charge monthly maintenance fees (ranging from $0 to $5 per month) and offer limited or no investment options — your money usually sits in a savings account earning minimal interest. Credit unions sometimes have lower fees. Call ahead to confirm they offer HSAs and ask about their fee structure.

At an investment firm: Brokerages like Fidelity, Vanguard, and Charles Schwab offer HSAs with investment options — you can hold stocks, bonds, and mutual funds inside the account. These accounts often have lower or no monthly fees but may require a minimum balance. Investment firms are useful if you plan to keep money in the account long-term and want growth potential beyond savings account rates.

Gather documents and complete enrollment

You will need proof of your HDHP coverage and basic personal information. Have your insurance card or a copy of your plan documents handy. The financial institution will ask for your name, address, Social Security number, and employment information.

If you are opening an account at a bank or investment firm, you can usually start online — the process takes 10 to 15 minutes. You will confirm your HDHP coverage (some institutions verify this directly with your insurance company; others accept a screenshot of your plan documents). If you are opening through your employer, HR will likely handle the setup during open enrollment or when you first become HDHP-may be able to access, and you may only need to choose which provider to use.

Once the account is open, you can begin contributing. If you are contributing through payroll deductions, your employer will set that up. If you are contributing on your own, you can transfer money from your bank account or set up automatic monthly transfers.

Understand contribution limits and timing

The IRS sets annual contribution limits that vary by coverage type. For 2024, you can contribute up to $4,150 for individual coverage or $8,300 for family coverage. These limits increase slightly each year. If you turn 55 during the year, you can add an extra $1,000 catch-up contribution.

You can contribute at any time during the year, but contributions for a specific tax year must be made by the tax filing important date — usually April 15 of the following year. For example, contributions for the 2024 tax year can be made through April 15, 2025. If you enroll in an HDHP mid-year, you can still contribute a full year's amount if you meet the "testing period" rules (generally, you must be HDHP-may be able to access on December 1 of that year).

If you lose HDHP coverage during the year, you can no longer contribute for that year, but you keep the money already in the account and can continue using it for may have access to medical expenses.

What happens after you open the account

Once your HSA is open, you receive a debit card or checkbook to pay for may have access to medical expenses directly from the account. You can also reimburse yourself for out-of-pocket medical costs you have already paid. Keep receipts — the IRS requires documentation if you are audited.

Money you do not spend in a given year rolls over to the next year; there is no "use it or lose it" important date like a flexible spending account. If you invest the money in your HSA and it grows, the growth is tax-free as long as you use withdrawals for may have access to medical expenses.

If you change jobs, your HSA stays with you — it is your account, not your employer's. You can roll it to a new provider if you want, though many people keep it where it is.

Frequently Asked Questions

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

Yes. You can open an HSA directly at a bank, credit union, or investment firm as long as you are enrolled in an HDHP. You will need to contribute on your own rather than through payroll deductions, but the account works the same way.

What if I am self-employed or a freelancer?

You can open an HSA if you have an HDHP, whether through the individual market or a professional association plan. You contribute on your own schedule and can deduct contributions on your tax return. Open the account at a bank or investment firm that accepts individual HSA holders.

Can I have an HSA and a Flexible Spending Account at the same time?

No. You cannot contribute to both an HSA and a dependent care FSA in the same year, and you cannot have a general-purpose FSA at all while you have an HSA. You can have an HSA and a limited-purpose FSA (which covers only dental and vision), but check your employer's plan rules first.

What if I miss the important date to open an HSA for this year?

You can open an HSA at any time, but contributions for a specific tax year must be made by April 15 of the following year. If you enroll in an HDHP in November, you can still contribute for that full year through the following April, as long as you remain HDHP-may be able to access through December 1.

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

You choose. If your HSA is at a bank, the money stays in a savings account by default. If it is at an investment firm, you can choose to invest it or leave it in cash. Many people keep a year or two of expected medical expenses in savings and invest the rest for long-term growth.
