You need a high-deductible health plan to open an HSA, whether through your employer or on your own

A Health Savings Account (HSA) is not something you can open independently of health insurance. You must be enrolled in a high-deductible health plan (HDHP) first — that is the gateway. If your employer does not offer an HDHP, you can buy one yourself through the health insurance marketplace, and then open an HSA with any bank or financial institution that offers them. The account itself is separate from the insurance, but the insurance is mandatory.

The process is straightforward: find an HDHP on your state's marketplace, enroll in it, then open an HSA account with a bank, credit union, or brokerage firm. You do not need your employer's permission or involvement. Many people do this when they are self-employed, between jobs, or simply want more control over their healthcare spending.

Key Takeaways

  • You must be enrolled in a high-deductible health plan to open an HSA; you cannot have one without it, even if you have the money to contribute.
  • You can buy an HDHP on your state's health insurance marketplace if your employer does not offer one, and then open an HSA with any bank or financial institution.
  • The IRS sets the minimum deductible for an HDHP each year; for 2024, it is $1,600 for individual coverage and $3,200 for family coverage, though these amounts change annually.
  • You can open an HSA account with a bank, credit union, or investment firm — you do not have to use the same institution where you bank or get insurance.
  • Once you enroll in an HDHP, you have until the tax filing deadline of the following year to open an HSA and make contributions for that year.

Finding and enrolling in an HDHP on the marketplace

Start by going to Healthcare.gov (or your state's marketplace if it runs its own) and entering your zip code and income. You will see plans sorted by metal level — Bronze, Silver, Gold, Platinum — and by price. Most Bronze and some Silver plans meet the HDHP definition, but the marketplace does not label them that way. You have to check the plan details.

Look at the deductible amount. For 2024, an HDHP must have a deductible of at least $1,600 for individual coverage or $3,200 for family coverage. The deductible is the amount you pay out of pocket before insurance starts to pay. If the plan meets that threshold and does not have a copay for primary care visits (or has only a small one), it is likely an HDHP. Some plans will say "HSA-may be able to access" in the description — that is the clearest signal.

Enroll during the open enrollment period (usually November 1 through January 15 each year) or if you have a may have access to life event like losing employer coverage, moving, or a change in income. Once you are enrolled, you will receive confirmation and your coverage start date. That is when you become may be able to access to open an HSA.

Opening an HSA account after you have the HDHP

You do not have to open an HSA with your insurance company or your bank. You can shop around. Common providers include banks like Chase and Bank of America, credit unions, and investment firms like Fidelity, Vanguard, and Lively. Each charges different fees and offers different investment options, so compare before you choose.

To open an account, you will need proof of your HDHP enrollment — usually a copy of your insurance card or enrollment confirmation from the marketplace. The financial institution will ask for your name, Social Security number, address, and employment status. If you are self-employed, you will likely need to provide that information, but it does not disqualify you.

Some institutions let you open an account online in minutes. Others require a phone call or a visit. Once the account is open, you can start contributing immediately, up to the annual limit set by the IRS. For 2024, the limit is $4,150 for individual coverage or $8,300 for family coverage. These limits change each year.

Contribution rules and timing

You can contribute to your HSA for the entire year you are enrolled in an HDHP, and you have until the tax filing deadline of the following year (usually April 15) to make contributions for the previous year. This is called the grace period. For example, if you enroll in an HDHP on September 1, 2024, you can contribute for the months of September through December 2024, and you can add more money until April 15, 2025 to cover those months.

If you enroll mid-year, your contribution limit is prorated. The IRS provides a worksheet to calculate it, but most HSA providers will do this for you automatically. You contribute with pre-tax dollars if you are employed (your employer deducts it from your paycheck) or with tax-deductible contributions if you are self-employed (you deduct it on your tax return).

You cannot contribute to an HSA if you are covered by Medicare, enrolled in Medicaid, or claimed as a dependent on someone else's tax return. You also cannot have other health coverage besides the HDHP — no spouse's plan, no Medicaid, no military coverage. If your situation changes mid-year, you must stop contributing immediately.

What happens if you lose your HDHP

If you switch to a different health plan that is not an HDHP, you can no longer contribute to your HSA, but you keep the account and the money in it. The balance stays yours indefinitely — there is no expiration date. You can continue to withdraw money for may have access to medical expenses tax-free, even if you are no longer enrolled in an HDHP.

If you withdraw money for non-medical expenses before age 65, you pay income tax on the withdrawal plus a 20 percent penalty. After age 65, you can withdraw money for any reason without the penalty, though you still pay income tax on non-medical withdrawals. This makes an HSA a powerful retirement savings tool if you do not spend the money while you are younger.

Comparing HSA providers and their fees

HSA providers vary widely in fees, investment options, and customer service. Some charge a monthly maintenance fee ($2 to $5), others charge per transaction, and some charge nothing if you keep a minimum balance. Some offer only savings accounts; others let you invest the balance in mutual funds or stocks.

If you plan to use your HSA to pay medical bills as they come up, a low-fee savings account is usually enough. If you want to invest the money for retirement, look for a provider that offers low-cost index funds and does not charge high investment fees. Read the fee schedule carefully before you open an account — fees compound over time and eat into your balance.

Self-employed and freelancer considerations

If you are self-employed or a freelancer, you can open an HSA as long as you have an HDHP. You buy the HDHP on the marketplace just like anyone else. The main difference is that you deduct your HSA contributions on your tax return (Schedule 1, line 12) rather than having your employer deduct them from your paycheck.

You also cannot claim the self-employed health insurance deduction for the portion of your premium that covers the HDHP — that is a technical rule, but it means you need to track your HDHP premium separately from any other health insurance you might have. If you have questions about the tax treatment, a tax professional or the IRS website can clarify the rules for your specific situation.
