Opening an HSA requires three things: a high-deductible health plan, a bank or financial institution that offers HSA accounts, and proof of your coverage
You cannot open an HSA on your own—it must be tied to a high-deductible health plan (HDHP), which is a specific type of health insurance. Your employer may offer one, or you can buy one through the health insurance marketplace during open enrollment. Once you have HDHP coverage, you can open an HSA account at a bank, credit union, or investment firm that administers them. You will need to show proof of your HDHP coverage when you open the account.
The process takes a few days to a week. You provide your coverage details, choose how much to contribute (up to the annual limit set by the IRS, which varies by year and whether you have individual or family coverage), and decide whether to keep the money in a savings account or invest it. Some employers set up HSAs automatically for their employees; others require you to initiate it yourself.
Key Takeaways
- You must be enrolled in an HDHP before opening an HSA; the account cannot exist without that coverage.
- You can open an HSA through your employer's plan administrator, a bank, a credit union, or an investment firm—each may charge different fees and offer different investment options.
- Contributions are made with pre-tax dollars if your employer sets it up, or through a tax deduction if you open it yourself, reducing your taxable income for that year.
- You can contribute money at any time during the year, but contributions for a tax year must be made by the tax filing deadline (usually April 15) to count toward that year's deduction.
Where to open an HSA account
Your employer is often the easiest route. If your company offers an HDHP, they usually partner with a specific HSA administrator—often a large bank or a dedicated HSA provider like HealthEquity, Lively, or Fidelity. Your HR or benefits department will give you the account setup information, and contributions are deducted directly from your paycheck before taxes.
If you buy your own HDHP through the marketplace or have coverage outside an employer plan, you choose the institution. Banks like Chase, Wells Fargo, and Ally offer HSAs. Credit unions often do as well. Investment firms like Fidelity, Vanguard, and Charles Schwab offer HSAs with investment options. Compare fees—some charge monthly maintenance fees, per-transaction fees, or investment management fees—and check whether they offer the investment choices you want. A basic savings HSA has no investment options and earns minimal interest; an HSA with investment access lets you buy stocks, bonds, or mutual funds with your balance.
What documents and information you will need
Have your health insurance information ready. You will need your policy number, the name of your insurance carrier, and the effective date of your coverage. If you are opening the account through your employer, HR will often provide this. If you are opening it independently, pull up your insurance documents or log into your carrier's website.
You will also need standard identification: your Social Security number, date of birth, and current address. Some institutions ask for a driver's license or passport. If you are opening the account online, you can usually complete this in 10 to 15 minutes. If you are opening it in person at a bank branch, bring your insurance card and a photo ID.
How to fund your HSA
If your employer offers the HSA, the simplest method is payroll deduction. You tell your benefits administrator how much to contribute each pay period, and that amount is deducted from your gross pay before taxes are calculated. This reduces your taxable income for the year. You can change your contribution amount during open enrollment or if you have a may have access to life event (marriage, birth, loss of coverage).
If you opened the account yourself, you can fund it by bank transfer, check, or automatic monthly transfer. You can contribute at any time during the year. However, if you want the contribution to count as a tax deduction for a specific tax year, you must make the contribution by the tax filing deadline for that year—typically April 15 of the following year. For example, contributions made by April 15, 2025 can count toward your 2024 tax deduction.
The IRS sets annual contribution limits, which change each year. These limits are higher if you have family coverage than individual coverage. Check the IRS website or your HSA provider for the current year's limit. You can contribute less than the limit, but you cannot exceed it without facing a tax penalty.
What happens after you open the account
Once your account is open and funded, you receive a debit card or checkbook (depending on the provider) that you can use to pay for may have access to medical expenses—doctor visits, prescriptions, dental work, vision care, and many other health-related costs. You can also withdraw money and pay out of pocket, then reimburse yourself from the HSA later, even years later, as long as you keep receipts.
Money you do not spend in a given year rolls over to the next year. Unlike a flexible spending account (FSA), there is no "use it or lose it" rule with an HSA. Your balance grows year after year, and if you invest it, it can earn returns. When you turn 65, you can withdraw money for any reason without penalty, though non-medical withdrawals are taxed as income.
Common mistakes to avoid when setting up
Do not open an HSA if you do not have an HDHP. The account will be rejected or closed if you lose HDHP coverage. If you are on Medicare, you cannot contribute to an HSA, though you can continue to withdraw from an existing balance for may have access to expenses.
Do not assume your employer's HSA is the only option. Even if your company sets one up automatically, you may be able to open a separate HSA elsewhere if that provider offers better investment options or lower fees. You can have multiple HSAs as long as your total contributions across all accounts do not exceed the annual limit.
Do not miss the tax filing deadline if you want to deduct contributions made outside payroll. If you open an HSA in December and want to contribute for that tax year, you have until April 15 to make the deposit. After that, contributions count toward the next year.
Frequently Asked Questions
Can I open an HSA if my employer does not offer one?
Yes. You can open an HSA at any bank, credit union, or investment firm that offers them, as long as you are enrolled in an HDHP. You will need to provide proof of your coverage. You can buy an HDHP through the health insurance marketplace during open enrollment or through a private insurer.
What if I change jobs or lose my HDHP coverage?
Your HSA stays with you. The account is yours, not your employer's. If you change jobs, you can keep the same HSA or move it to a new provider. If you lose HDHP coverage, you can no longer contribute to the HSA, but you can continue to withdraw money for may have access to medical expenses. If you regain HDHP coverage later, you can resume contributions.
Can I invest the money in my HSA?
Only if your HSA provider offers investment options. Some HSAs are savings-only; others let you invest in mutual funds, stocks, or bonds. Check with your provider before opening the account. Investment HSAs typically have higher fees but allow your balance to grow faster over time.
What counts as a may have access to medical expense?
may have access to expenses include doctor visits, hospital care, prescriptions, dental work, vision care, mental health treatment, and medical equipment. Over-the-counter medications do not count unless prescribed by a doctor. Cosmetic procedures, gym memberships, and vitamins do not count. The IRS publishes a full list on its website.
Do I have to use my HSA debit card, or can I pay out of pocket?
You can do either. You can use the HSA debit card to pay directly, or you can pay with your own money and reimburse yourself from the HSA later. Many people reimburse themselves years later to let the account grow. Keep receipts for all expenses you plan to reimburse yourself for.
