You need an HSA-may be able to access health plan first, then open an account at a bank or financial institution

You cannot open a Health Savings Account without being enrolled in a High Deductible Health Plan (HDHP). The HDHP is the gateway — your health insurance company or employer must offer one, and you must be actively covered by it. Once you have the HDHP in place, you can open an HSA at a bank, credit union, or investment firm. Some employers offer HSAs directly through payroll, which makes funding automatic; others require you to find your own provider and set up contributions yourself.

The timing matters. You can open an HSA only during the months you are covered by an HDHP. If you switch to a different health plan that does not may have access to, you can no longer contribute to the account, though you keep the money already inside it. If you enroll in Medicare, you must stop contributing immediately, even if you still have an HDHP through a spouse's employer.

Key Takeaways

  • Your employer or health insurance company must offer an HDHP; you cannot open an HSA without one, and you must be enrolled in it to contribute.
  • You can open an HSA at your employer's plan administrator, at a bank, credit union, or brokerage firm, or through a third-party HSA provider.
  • Contributions can come from your paycheck (pre-tax), from your own bank account (tax-deductible on your return), or from both.
  • You must report your HSA on your tax return if you contribute outside of payroll, and you must verify each year that you still meet the coverage requirements.

Confirm your HDHP meets the IRS definition

Not every high-deductible plan qualifies for an HSA. The IRS sets minimum deductibles and maximum out-of-pocket limits that change each year. For 2024, a self-only HDHP must have a deductible of at least $1,600 and out-of-pocket maximum of no more than $8,050; a family plan must have a deductible of at least $3,200 and out-of-pocket maximum of no more than $16,100. Your health insurance company will tell you whether your plan is HSA-may be able to access — check your plan documents or call the number on your insurance card.

Some plans are labeled "high deductible" but do not meet the IRS thresholds, so they do not may have access to. Others meet the thresholds but exclude preventive care from the deductible in a way that disqualifies them. If you are unsure, ask your employer's benefits administrator or your insurance company directly whether your plan is HSA-may be able to access. Do not assume based on the plan name alone.

Choose where to open your account

You have three main routes. Employer-sponsored HSAs are the simplest: your employer contracts with a provider (often a bank or third-party administrator), and you enroll during open enrollment or when you first become may be able to access. Contributions come straight from your paycheck, pre-tax, and the employer often handles all the paperwork. Bank and credit union HSAs let you open an account directly at a financial institution; you fund it yourself and claim the tax deduction on your tax return. Third-party HSA providers (companies that specialize in HSAs) offer investment options and often lower fees than banks, but require you to manage contributions and tax reporting yourself.

If your employer offers an HSA, start there — payroll deduction is the easiest path and you avoid the tax-filing step. If your employer does not offer one, or if you are self-employed or have a spouse's HDHP, compare banks and third-party providers on fees (monthly maintenance, per-transaction charges), investment options, and customer service. Some charge nothing; others charge $2 to $5 per month. Over time, those fees add up.

Gather documents and information you will need

To open an HSA, have your Social Security number, proof of identity (driver's license or passport), and proof of your HDHP coverage ready. If you are opening through your employer, the benefits administrator will have your coverage information already. If you are opening at a bank or third-party provider, you will need to provide your plan name, the name of your health insurance company, and your policy number — all of which appear on your insurance card or in your plan documents.

You will also need to decide how much to contribute for the year. The IRS sets annual contribution limits: for 2024, $4,150 for self-only coverage and $8,300 for family coverage. If you are 55 or older, you can contribute an extra $1,000 per year (called a catch-up contribution). You do not have to contribute the maximum — contribute what you can afford and what makes sense for your expected medical costs.

Set up contributions through payroll or direct deposit

If your employer offers the HSA, enroll during open enrollment or when you first become may be able to access for the HDHP. You will choose a contribution amount, and that amount will be deducted from your paycheck before taxes are calculated. This is the most tax-efficient route because the money never touches your taxable income. Your employer may also contribute to your account — many do as part of their benefits package.

If you are opening an HSA outside of payroll, you can fund it by transferring money from your bank account. You will then claim the contribution as a tax deduction on your tax return (Form 1040, Schedule 1, line 12). This requires you to file a tax return and keep records of your contributions. Some people set up automatic monthly transfers to make funding easier and more consistent.

Verify your may be able to access each year

HSA may be able to access is not permanent — you must meet the requirements every month you want to contribute. If you drop your HDHP and enroll in a different health plan, you must stop contributing immediately. If you turn 65 and enroll in Medicare, you must stop contributing that month. If you become covered by a spouse's non-HDHP plan, you lose may be able to access. Your employer or HSA provider will not always catch these changes, so it is your responsibility to monitor your coverage.

At tax time, you will report your HSA contributions on your tax return. If you contributed through payroll, your employer will report it on your W-2 form and you will enter it on your return. If you contributed outside of payroll, you will report it yourself and keep receipts or bank statements as proof. If you contributed while ineligible (for example, after switching to a non-HDHP plan), you will owe taxes and a 20 percent penalty on that contribution.

Understand what happens after you open the account

Once your account is open, you receive a debit card or checkbook to pay for medical expenses directly from the HSA. You can also withdraw money by transferring it to your bank account. Keep receipts for all medical expenses you pay from the HSA — the IRS does not require you to submit them when you withdraw, but you must be able to prove the expense was medical if you are audited. Medical expenses include doctor visits, prescriptions, dental work, vision care, mental health treatment, and many other services; they do not include cosmetic procedures or most over-the-counter medications (though some do may have access to).

Money you do not spend stays in the account and rolls over to the next year — there is no "use it or lose it" rule like some other health benefit accounts. If you withdraw money for non-medical expenses before age 65, you owe income tax on that amount plus a 20 percent penalty. After age 65, you can withdraw for any reason without penalty, though you still owe income tax on non-medical withdrawals.

Frequently Asked Questions

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

Yes. You can open an HSA at a bank, credit union, or third-party HSA provider as long as you are enrolled in an HSA-may be able to access HDHP. You will need to contribute from your own bank account and report the contribution on your tax return. Some employers do not offer HSAs even though they offer HDHPs, so this is a common situation.

What if I enroll in an HDHP mid-year?

You can open an HSA and contribute for the months you are covered by the HDHP. Your contribution limit is reduced proportionally — if you enroll in July, you can contribute roughly 7/12 of the annual limit. If you enroll on the first day of a month, that month counts; if you enroll mid-month, that month still counts as a full month for contribution purposes.

Do I have to use the HSA debit card, or can I pay out of pocket and reimburse myself later?

You can do either. Some people pay medical bills from their regular bank account and then withdraw from the HSA later, or transfer HSA money to their checking account. This can be useful if you want to let the HSA grow and invest the money. Keep receipts for any expenses you reimburse yourself for, in case the IRS asks.

What if I miss the deadline to open an HSA?

There is no single deadline — you can open an HSA any time you are covered by an HDHP. However, if you want to make contributions for the current year, you must open the account by December 31 of that year. You can also make contributions for the prior year until the tax filing deadline (usually April 15) if you open the account by that date.

Can my spouse and I share one HSA?

No. Each person with an HDHP must have their own HSA. If you are both covered by family HDHPs, you each open separate accounts. You cannot combine them or transfer money between them, though you can both contribute up to the family coverage limit if you coordinate your contributions.
