How to set up an HSA in three steps

To open a Health Savings Account, you need an HSA-may be able to access high-deductible health plan (HDHP), a bank or financial institution that offers HSA accounts, and proof of your coverage. The process takes about 15 to 30 minutes online or by phone, and you can start contributing immediately after approval. Most employers offer HSA setup through payroll, which is the fastest route; if you buy your own insurance, you'll open the account directly with a bank or investment firm.

The three steps are: verify your HDHP meets HSA requirements, choose an HSA provider, and complete the account application. You don't need to do all three on the same day, but you must have the HDHP in place before you can fund the account.

Key Takeaways

  • You must be enrolled in an HDHP to open an HSA; a regular health plan or Medicare makes you ineligible.
  • If your employer offers an HSA, payroll deduction is the simplest setup method and contributions are deducted before taxes.
  • If you buy your own insurance, you can open an HSA with any bank, credit union, or brokerage that offers them—not just your insurance company.
  • You have until April 15 of the following year to contribute for the current tax year, so you don't need to fund the account immediately after opening it.

Verify your health plan meets HSA requirements

Before you open an account, confirm that your health plan is HSA-may be able to access. An HDHP must have a minimum deductible (the amount varies by year and whether coverage is individual or family) and a maximum out-of-pocket limit. For 2024, the minimum deductible is $1,600 for individual coverage and $3,200 for family coverage; the maximum out-of-pocket is $8,050 for individual and $16,100 for family. These numbers change annually.

If you have employer coverage, your benefits summary or plan documents will state whether the plan is HSA-may be able to access. If you buy insurance through the marketplace or directly from an insurer, search for plans labeled "HSA-may be able to access" or "HDHP." You cannot have an HSA if you're on Medicare, covered by a spouse's non-HDHP, or enrolled in a health plan with a deductible below the HSA minimum.

Choose your HSA provider

An HSA provider is a bank, credit union, or investment firm that holds and manages the account. If your employer offers an HSA through payroll, they've already chosen the provider for you—you'll use that one. If you're self-employed or your employer doesn't offer an HSA, you can open an account with any provider you choose.

Common HSA providers include large banks (Chase, Bank of America, Wells Fargo), credit unions, online banks (Lively, HealthEquity, Fidelity), and investment brokerages. Compare them on three things: whether they charge monthly maintenance fees (many waive fees if you maintain a minimum balance), what investment options they offer if you want to invest HSA funds rather than keep them in cash, and whether they provide a debit card or online portal for easy access to your money. Some providers charge per transaction or per investment trade, so read the fee schedule before you decide.

Complete the account application

If your employer offers an HSA, enrollment usually happens during open enrollment or when you first become may be able to access. You'll fill out a form (on paper or through your employer's benefits portal) that asks for your name, Social Security number, and confirmation that you're enrolled in an HSA-may be able to access plan. Your employer then sends your information to the HSA provider, and the account opens within a few business days.

If you're opening an account on your own, go to the provider's website or call their customer service line. You'll need your Social Security number, proof of your HDHP (your insurance card or a copy of your plan documents showing the deductible and out-of-pocket maximum), and a way to fund the account (bank account for transfers, or paycheck if you're self-employed). The application takes 10 to 20 minutes, and most providers approve accounts the same day or within one business day.

Fund your account

You can contribute to your HSA in several ways. If your employer offers an HSA, the easiest method is payroll deduction—you authorize your employer to transfer a portion of your paycheck to the HSA before taxes are withheld. This reduces your taxable income and is the most common setup for people with employer coverage.

If you're self-employed or your employer doesn't offer payroll deduction, you can transfer money directly from your bank account to your HSA using online banking, ACH transfer, or check. You can also make a lump-sum contribution at any time during the year. The IRS sets annual contribution limits (for 2024, $4,150 for individual coverage and $8,300 for family coverage), and you can contribute up to that limit regardless of how much you earn or when you open the account.

You have until April 15 of the following year to make contributions for the current tax year. For example, you can contribute to your 2024 HSA anytime between January 1, 2024, and April 15, 2025. This gives you time to open the account and fund it at your own pace.

What happens after you open the account

Once your HSA is open and funded, you can use the money to pay for may have access to medical expenses—doctor visits, prescriptions, dental work, vision care, and many other health costs. Most HSA providers give you a debit card linked to the account, so you can pay at the point of care. You can also withdraw money by check, transfer, or online banking.

Keep receipts for all medical expenses you pay with HSA funds. The IRS doesn't require you to submit receipts when you withdraw money, but you must keep them for your records in case of an audit. If you withdraw money for a non-medical expense before age 65, you'll owe income tax on the withdrawal plus a 20% penalty. After age 65, you can withdraw money for any reason without the penalty, though non-medical withdrawals are still taxable income.

If your employer changes or you lose coverage

Your HSA stays with you even if you change jobs or lose your health insurance. The account is yours to keep, and the money in it is yours to use. However, you can only make new contributions while you're enrolled in an HSA-may be able to access plan. If you leave your job and don't immediately enroll in another HDHP, you can't contribute to the HSA until you're covered by an HDHP again.

If your employer's HSA provider changes, your old provider will transfer your balance to the new one, or you can request a direct transfer yourself. You won't lose any money in the process. If you want to move your HSA to a different provider on your own (for lower fees or better investment options), you can request a trustee-to-trustee transfer, which takes about two weeks and doesn't count against your annual contribution limit.

Frequently Asked Questions

Can I open an HSA if I'm self-employed?

Yes. You need an HSA-may be able to access health plan, which you can buy through the marketplace or directly from an insurer. Once you have the plan, you can open an HSA with any provider and contribute up to the annual limit. You'll report contributions on your tax return (Form 8889) when you file.

What if I miss the deadline to open an HSA for this year?

You can open an HSA at any time during the year. If you open it mid-year, you can still contribute the full annual amount, but you have until April 15 of the following year to make that contribution. You don't lose contribution room just because you opened the account late.

Do I have to invest my HSA money, or can I just keep it in cash?

You can do either. Most HSA providers let you keep your balance in a cash account (similar to a savings account) or invest it in mutual funds, stocks, or other options. Cash is simpler and safer; investing gives you the potential for growth but carries risk. Many people keep a portion in cash for near-term medical expenses and invest the rest.

What if I don't use all my HSA money in a year?

HSA money rolls over year to year—there's no "use it or lose it" rule. You can let the balance grow and use it whenever you need it, even years later. This is one of the main advantages of an HSA over a Flexible Spending Account (FSA).

Can my spouse and I share one HSA?

No. Each person needs their own HSA account. If you both have family coverage under the same HDHP, you each open separate accounts and can each contribute up to the family contribution limit (split between you however you choose).
