You open an HSA through your employer's health plan or directly from a bank or insurance company, but only if you have a may have access to high-deductible health plan

An HSA account is a savings account paired with a high-deductible health plan (HDHP). You cannot open one without the HDHP first — that is the requirement. If your employer offers an HDHP, they usually handle the HSA setup for you during open enrollment or when you first join. If you buy your own health insurance, you can open an HSA directly with a bank, credit union, or insurance company that offers them, as long as your plan meets the IRS definition of a high-deductible plan.

The account itself is separate from your health insurance. Your employer or insurance company does not manage the money inside it — you do. You choose where to keep it (a bank, a brokerage, or an insurance company's HSA program), how much to contribute each year, and how to spend it. The money rolls over year to year, unlike a Flexible Spending Account (FSA), which you lose if you do not use.

Key Takeaways

  • You must be enrolled in a high-deductible health plan to open an HSA; without one, the account cannot be opened or funded.
  • If your employer offers an HDHP, they usually set up the HSA automatically during enrollment, and you choose the account provider from a list they give you.
  • If you buy your own insurance, you open an HSA directly with a bank, credit union, or brokerage that offers them, as long as your plan meets IRS requirements.
  • You can contribute up to a set annual limit (the amount changes each year), and the money stays in the account indefinitely if you do not spend it.

Opening an HSA through your employer

During open enrollment or when you first become may be able to access for your employer's HDHP, you will see HSA options listed alongside the health plan itself. Your employer usually contracts with one or more HSA providers — often a bank, insurance company, or third-party administrator — and gives you a choice of which one to use. You select the provider, fill out an enrollment form (usually online), and the account opens within a few days.

Your employer may also set up automatic payroll deductions so that contributions come straight from your paycheck before taxes. This is the most common route and requires almost no work on your part beyond choosing the provider and the contribution amount. If your employer does not offer automatic deductions, you can still contribute on your own, but you will need to do it manually and claim the tax deduction when you file your taxes.

Some employers contribute money to your HSA as part of their benefits package. If yours does, that money appears in your account automatically. You can then add your own contributions on top of it, up to the annual limit set by the IRS.

Opening an HSA on your own if you have individual insurance

If you buy your own health insurance and it is a high-deductible plan, you can open an HSA directly with a financial institution. Common providers include banks (like Fidelity, Lively, and HealthEquity), credit unions, and insurance companies. Search for "HSA provider" or "HSA account" and you will find dozens of options. Each one has different fees, investment choices, and user interfaces, so comparing a few is worth your time.

To open an account, you will need your health insurance information — specifically, proof that your plan meets the IRS definition of a high-deductible plan. Your insurance company or the plan documents will state whether it qualifies. You provide this information when you sign up, and the HSA provider verifies it. Once verified, your account opens and you can begin contributing.

You contribute money on your own schedule, either as a lump sum or in regular installments. You will claim the contribution as a tax deduction when you file your taxes, or if you use a payroll deduction through a self-employed retirement plan, you can deduct it directly from your income.

What information you need to open an account

Whether you open an HSA through your employer or on your own, you will need basic personal information: your name, address, Social Security number, and date of birth. You will also need your health insurance information — the plan name, policy number, and confirmation that it is a high-deductible plan. If you are opening through an employer, they usually provide this automatically. If you are opening on your own, have your insurance documents or a letter from your insurance company handy.

Some providers ask for your employer's name and address, especially if you are opening through a workplace plan. A few also ask about your income or employment status, but this is less common. The process is straightforward and takes 10 to 20 minutes online.

Annual contribution limits and how they work

The IRS sets an annual limit on how much you can contribute to an HSA each year. The limit changes yearly and depends on whether your health plan covers only you or also covers dependents. For 2024, the limit is $4,150 for individual coverage and $8,300 for family coverage, but these amounts change — check the IRS website or your HSA provider for the current year's limit.

You can contribute the full annual amount in one payment or spread it across the year in smaller contributions. If you contribute through payroll deductions, your employer usually divides your annual contribution into equal amounts across each pay period. If you contribute on your own, you can contribute whenever you want, as long as the total does not exceed the annual limit.

If you open an HSA partway through the year, you can still contribute the full annual amount for that year — you do not have to prorate it. However, if you close the account or lose your high-deductible plan coverage before the end of the year, you can only contribute up to the month you had coverage.

Investment options and account management

Once your account is open, you can keep the money in a cash savings account (which earns a small amount of interest) or invest it in mutual funds, stocks, or other securities, depending on what your HSA provider offers. Some providers let you do both — keep a portion in cash for immediate medical expenses and invest the rest for long-term growth.

You manage the account through an online portal or mobile app. You can see your balance, view your contribution history, and request withdrawals. When you need to pay for a medical expense, you can either pay out of pocket and then withdraw money from your HSA to reimburse yourself, or use a debit card linked to the account (if your provider offers one) to pay directly.

You are responsible for keeping records of your medical expenses. The HSA provider does not verify whether your withdrawal is for a may have access to medical expense — that is your responsibility. If you withdraw money for a non-medical reason before age 65, you owe income tax on it plus a 20 percent penalty. After age 65, you can withdraw money for any reason without the penalty, though you still owe income tax on non-medical withdrawals.

Changing HSA providers or closing an account

You can switch HSA providers at any time. If you move your account to a different provider, you initiate a direct transfer (also called a trustee-to-trustee transfer) so that the money moves without tax consequences. The process usually takes one to two weeks. You do not have to close your old account before opening a new one — you can keep both open if you want, though most people close the old one once the transfer is complete.

If you lose your high-deductible plan coverage — for example, because you switch to a different health plan or your employer stops offering an HDHP — you can no longer contribute to the HSA, but you can keep the account open and use the money that is already in it for medical expenses. The money does not disappear. You can withdraw it whenever you need it for may have access to medical costs, and it will stay in the account indefinitely if you do not spend it.

Frequently Asked Questions

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

Yes. If your employer does not offer an HSA but you have your own high-deductible health plan, you can open one directly with a bank, credit union, or insurance company. You will contribute on your own and claim the deduction on your taxes. Your plan must meet the IRS definition of a high-deductible plan, which your insurance company can confirm.

What happens to my HSA if I change jobs?

Your HSA stays with you. The money in the account is yours, not your employer's. If your new employer offers an HSA, you can keep your old account or open a new one with them — the choice is yours. If your new employer does not offer an HSA, you keep your existing account and can continue to use it for medical expenses.

Can I have both an HSA and an FSA at the same time?

No. If you have an FSA through your employer, you cannot contribute to an HSA in the same year. However, there is an exception: a limited-purpose FSA that covers only dental and vision expenses allows you to also have an HSA. Check with your employer about whether this option is available.

Do I need to use my HSA every year or I lose the money?

No. Unlike an FSA, money in an HSA rolls over year to year. You do not have to spend it by December 31 or lose it. The money stays in the account indefinitely, which is one of the main advantages of an HSA over an FSA.

What if I do not have any medical expenses — can I just leave the money in the account?

Yes. You can leave money in your HSA indefinitely without spending it. After age 65, you can withdraw it for any reason without the 20 percent penalty (though you will owe income tax on non-medical withdrawals). This makes an HSA useful as a long-term savings tool if you have the money to cover medical expenses out of pocket.
