You need a high-deductible health plan first, then you can open an HSA with a bank or investment firm

An HSA is not something you get from your employer or the government. You open one yourself at a bank, credit union, or investment company — the same way you would open a savings account or brokerage account. But there is a requirement: you must be enrolled in a high-deductible health plan (HDHP) through your job, the marketplace, or Medicare. Without that plan, you cannot open or contribute to an HSA, and if you already have one, you lose the ability to add money to it.

The HDHP is the gatekeeper. Your health insurance company does not open the HSA for you. They straightforward confirm that your plan meets the IRS definition of high-deductible, which changes each year. Once you have that plan in place, you choose where to open your account and how much to contribute.

Key Takeaways

  • You must be enrolled in a high-deductible health plan to open an HSA; your insurance company will not open one for you.
  • You can open an HSA at any bank, credit union, or brokerage firm that offers them, and you choose the institution yourself.
  • Annual contribution limits are set by the IRS and vary depending on whether you have individual or family coverage.
  • You can contribute through payroll deduction (if your employer offers it), a direct transfer from your bank, or a check deposit.
  • Once you have an HDHP, you can open an HSA at any time during the year, though contributions for that tax year have a important date in April of the following year.

Confirm your health plan meets the HDHP definition

Before you open an account, verify that your current health plan actually qualifies. The IRS sets minimum deductibles and maximum out-of-pocket limits each year. For 2024, an individual plan must have a deductible of at least $1,600 and family coverage at least $3,200. These numbers change annually.

Your insurance company should tell you whether your plan is HSA-may be able to access. Look at your plan documents or call the number on your insurance card and ask directly: "Is this plan HSA-may have access to?" If you are shopping for coverage on the marketplace or through your employer, the plan will be labeled as HSA-may be able to access or HSA-compatible. If your plan is not high-deductible, you cannot open an HSA, even if you want to.

Choose a bank, credit union, or investment firm to open your account

Once you have confirmed your HDHP, you can open an HSA with any financial institution that offers them. Large banks like Chase, Bank of America, and Fidelity offer HSAs. Credit unions often do as well. Some employers partner with a specific HSA provider and make it straightforward to enroll through payroll, but you are not required to use that provider — you can open an account elsewhere if you prefer.

Compare what each institution charges. Some HSAs have monthly maintenance fees, some charge per transaction, and some are free. Some allow you to invest the money in stocks and mutual funds; others keep it in a savings account earning interest. If you plan to use the account only to pay current medical bills, a straightforward savings account may be enough. If you want to let the money grow over time, look for an HSA that offers investment options.

You will need your Social Security number, proof of identity, and proof of your HDHP enrollment (your insurance card or a letter from your employer). Some institutions let you open an account online in minutes; others require a phone call or in-person visit.

Set up contributions through payroll or direct transfer

Once your account is open, you decide how much to contribute each year. The IRS sets annual limits: 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 your employer offers an HSA plan, the easiest route is payroll deduction. You authorize your employer to transfer a set amount from each paycheck into your HSA. This money comes out before taxes, which reduces your taxable income. You fill out a form with your employer's benefits department and your HSA account details.

If you do not have payroll deduction available, or if you are self-employed, you can transfer money directly from your bank account to your HSA. You can also write a check. The contribution important date for any tax year is April 15 of the following year — so contributions for 2024 can be made until April 15, 2025.

Understand the tax treatment of your contributions

Money you contribute to an HSA is tax-deductible, meaning it lowers your taxable income for that year. If you contribute through payroll deduction, the deduction happens automatically. If you contribute on your own, you claim the deduction on your tax return using Form 8889.

The money in your HSA grows tax-free, and withdrawals for may have access to medical expenses are also tax-free. may have access to expenses include deductibles, copays, coinsurance, prescription drugs, dental work, vision care, and many other medical costs. The IRS publishes a full list of what counts.

If you withdraw money for something that is not a may have access to medical expense, you pay income tax on that amount plus a 20 percent penalty — unless you are over 65, disabled, or no longer enrolled in an HDHP. After age 65, you can withdraw money for any reason without the penalty, though non-medical withdrawals are still taxed as income.

What happens if you change jobs or lose your HDHP

Your HSA stays with you even if you change employers or switch health plans. The account is yours, not your employer's. If you move to a new job with a different HDHP, you can keep contributing to the same HSA or open a new one — the choice is yours.

If you lose your HDHP coverage — because you switched to a plan with a lower deductible, enrolled in Medicare, or gained coverage through a spouse — you can no longer contribute new money to your HSA. But the money already in the account stays there and can still be used for may have access to medical expenses, tax-free, for the rest of your life. You straightforward cannot add to it.

Track your spending and keep receipts

You do not have to submit receipts to your HSA provider when you withdraw money for medical expenses. But the IRS can ask for proof that your withdrawals were for may have access to expenses, so you should keep receipts and medical bills for at least three years. Many HSA providers offer a mobile app or online portal where you can upload receipts and track which expenses you have paid for.

Some people use their HSA like a checking account, withdrawing money as they pay medical bills. Others let the money accumulate and invest it, using it only when they have large medical expenses or in retirement. Both approaches are allowed. There is no "use it or lose it" rule — money you do not spend in one year rolls over to the next year indefinitely.

Frequently Asked Questions

Can I open an HSA if I am on Medicare?

No. Once you enroll in Medicare Part A or Part B, 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 still use it for may have access to medical expenses, but you cannot add new contributions. Some people delay Medicare enrollment to keep contributing to an HSA, but that decision has other tax consequences worth discussing with a tax professional.

What if my employer does not offer an HSA plan?

You can still open an HSA on your own if you buy an HDHP through the marketplace or are self-employed. You will contribute the money yourself rather than through payroll deduction, but the tax treatment is the same — you deduct the contribution on your tax return and the growth is tax-free.

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. You can have an HSA and a limited-purpose FSA (which covers only dental and vision), but not a general medical FSA. If your employer offers both, you have to choose one.

What if I contribute too much to my HSA?

If you exceed the annual limit, the excess amount is taxed as income and subject to a 6 percent penalty each year it remains in the account. You can correct this by withdrawing the excess and any earnings on it before your tax return important date. If you catch the error on your tax return, you can claim a correction on Form 8889.

Can I use my HSA to pay for health insurance premiums?

Only in specific situations. You can use HSA money to pay premiums for COBRA coverage, long-term care insurance, or health insurance while you are receiving unemployment benefits. You cannot use it for regular health insurance premiums, including marketplace plans, unless you are over 65 and on Medicare.
