How to Open and Fund an HSA

You need a high-deductible health plan first, then choose a bank or financial institution to hold the account

An HSA (Health Savings Account) is not something you can open on its own. Your health insurance must be a high-deductible health plan (HDHP) — a specific category defined by the IRS with minimum deductibles and maximum out-of-pocket limits that change each year. Once you have that insurance, you can open an HSA through a bank, credit union, or investment firm. The account itself is separate from your insurance, but you cannot contribute to it without the HDHP in place.

The process takes a few days to a few weeks depending on your bank and whether you already have an account there. You will need your Social Security number, proof of HDHP coverage, and a way to fund the account — either through payroll deduction (if your employer offers it) or a direct transfer from your bank.

Key Takeaways

• Your health insurance must be a high-deductible health plan; you cannot open an HSA with any other type of coverage.
• You choose the financial institution that holds your HSA — it does not have to be the same company that sold you the insurance.
• Payroll deduction is the fastest way to fund an HSA if your employer offers it, because contributions are taken before taxes.
• You can open an HSA at any time during the year, but contributions for a tax year must be made by the tax filing deadline (usually April 15).
• The IRS sets annual contribution limits that vary by whether you have self-only or family coverage.

Confirm your health plan meets the HDHP definition

Before you contact a bank, check your insurance documents or your insurer's website to confirm you have an HDHP. The IRS updates the minimum deductible and maximum out-of-pocket amounts every January. For 2024, an HDHP for self-only coverage must have a deductible of at least $1,600 and out-of-pocket maximum of no more than $8,050; for family coverage, the deductible must be at least $3,200 and the out-of-pocket maximum no more than $16,100. These numbers change annually.

If you are unsure whether your plan qualifies, call your insurance company's customer service line and ask directly: "Is this plan an IRS-may have access to high-deductible health plan?" They will tell you yes or no. Do not assume based on the deductible alone — some plans have high deductibles but do not meet the other IRS requirements.

If your current plan is not an HDHP, you can switch during the next open enrollment period (usually November through December for coverage starting January 1) or if you have a may have access to life event such as losing other coverage, moving, or getting married.

Choose a financial institution to open your HSA

You can open an HSA at most banks, credit unions, and investment firms. Common providers include Fidelity, Lively, HealthEquity, Optum Bank, and your own bank if it offers HSAs. Shop around because fees and investment options vary. Some accounts charge monthly maintenance fees ($2 to $5), some charge per transaction, and some are free. If you plan to invest the money rather than just use it for near-term medical expenses, check whether the provider offers low-cost investment options like index funds.

You do not have to use the HSA provider your employer recommends, though many employers partner with one provider and make payroll deduction easier through that partner. If your employer offers payroll deduction, using their partner is usually simpler, but you can always open an account elsewhere and transfer money in later.

Once you have chosen a provider, go to their website or visit a branch in person. You will need your Social Security number, date of birth, and proof that you have an HDHP. Some providers ask you to upload a copy of your insurance card or a letter from your insurer; others just ask you to confirm the coverage type.

Fund your account through payroll or direct transfer

If your employer offers HSA payroll deduction, this is the fastest and most tax-efficient route. Your employer will deduct contributions from your paycheck before income tax is calculated, so you avoid federal income tax, Social Security tax, and Medicare tax on that money. You typically elect payroll deduction during your employer's open enrollment period or when you first become may be able to access for the HDHP.

If your employer does not offer payroll deduction, or if you are self-employed or have individual coverage, you can fund the account yourself through a direct transfer from your bank. Log into your HSA provider's website, provide your bank account information, and transfer money. This takes one to three business days. You will then deduct the contribution on your tax return (Form 1040, Schedule 1) to get the tax benefit.

You can also fund an HSA by check or by rolling over money from another HSA if you change providers. The key deadline is the tax filing deadline (usually April 15 of the following year) — contributions made by that date count toward the prior year's limit.

Understand the annual contribution limits

The IRS sets a maximum amount you can contribute to an HSA each year. For 2024, the limit is $4,150 for self-only coverage and $8,300 for family coverage. These limits increase most years. If you turn 55 during the year, you can contribute an additional $1,000 (called a catch-up contribution) for that year and every year after until you enroll in Medicare.

If you have family coverage but only you and your spouse are enrolled in the HDHP, you still use the family limit, not two self-only limits. If you change from self-only to family coverage mid-year, the IRS allows you to contribute a prorated amount for the months you had each type of coverage, or in some cases the full family limit — the rules are complex, so ask your HSA provider or tax preparer.

If you contribute more than the limit, you owe income tax on the excess plus a 6% penalty tax for each year the excess sits in the account. The penalty applies every year until you withdraw the excess, so it is important to track your contributions and stay within the limit.

Set up how you will use the account

Once your account is open and funded, decide how you will access the money. Most HSA providers give you a debit card that you can use at pharmacies, doctors' offices, and other medical providers. Some require you to submit receipts for reimbursement instead. A few offer both options.

You can also leave the money in the account and invest it in mutual funds or other securities, letting it grow tax-free for future medical expenses. This is a long-term strategy — you do not have to spend the money in the year you contribute it. The account has no "use it or lose it" rule like a Flexible Spending Account (FSA).

Keep receipts for any medical expenses you pay out of pocket, even if you do not reimburse yourself immediately. If the IRS ever audits your HSA, you may need to prove that withdrawals were for may have access to medical expenses. may have access to expenses include doctor visits, prescriptions, dental work, vision care, and many other health-related costs, but not insurance premiums (with limited exceptions) or over-the-counter medications without a prescription.

What happens if you lose HDHP coverage

If you switch to a non-HDHP plan (such as a PPO or HMO without a high deductible), you can no longer contribute to your HSA starting the month your new coverage begins. The money already in the account stays there and remains tax-free for may have access to medical expenses, but you cannot add more.

If you lose health insurance entirely, you also cannot contribute. However, there is a grace period: if you regain HDHP coverage within 12 months, you can resume contributions. If you do not regain HDHP coverage within that window, you can still withdraw the existing balance for medical expenses without penalty, though you will owe income tax on the amount.

If you enroll in Medicare, you can no longer contribute to an HSA starting the month you become may be able to access for Medicare. You can still withdraw money for may have access to medical expenses, and Medicare premiums and long-term care insurance premiums are considered may have access to expenses for HSA purposes.

Frequently Asked Questions

Can I open an HSA if I am covered under my spouse's health plan?

Yes, if your spouse's plan is an HDHP and you are both enrolled in it. You would use the family contribution limit, not two separate self-only limits. If your spouse has an HDHP but you have different coverage, you cannot contribute to an HSA.

What if I open an HSA but then realize my plan is not actually an HDHP?

Contact your HSA provider and your insurance company immediately. If you contributed money based on ineligible coverage, you will need to withdraw the excess contributions and any earnings on them by the tax filing deadline to avoid penalties. Your tax preparer can help you file an amended return if needed.

Can I have more than one HSA at the same time?

You can have accounts at multiple institutions, but your total contributions across all accounts cannot exceed the annual limit. If you open a second account, you must track contributions carefully to avoid exceeding the limit and triggering the 6% penalty.

Do I have to use my employer's HSA provider?

No. You can open an HSA at any bank or financial institution that offers them. Using your employer's provider may make payroll deduction simpler, but you are not required to. You can even open an account elsewhere and have your employer deposit contributions there if you provide the account details.

What if I do not have an employer — can I still open an HSA?

Yes. If you are self-employed or have individual health insurance, you can open an HSA as long as your coverage is an HDHP. You will fund it through direct transfer from your bank rather than payroll deduction, and you will deduct the contribution on your tax return.
