You need three things to open an HSA: a may have access to high-deductible health plan, a bank or financial institution that offers HSA accounts, and proof of your enrollment

An HSA is a savings account tied to your health insurance, not a standalone product you can open on your own. The first step is confirming that your health plan qualifies — your insurance company will tell you this when you enroll, or you can check your plan documents for the words "HSA-may be able to access" or "high-deductible health plan." Once you know you have a may have access to plan, you choose where to open the account: your health insurance company often offers one, but you can also use a bank, credit union, or financial services company that administers HSAs.

The actual opening process takes 15 to 30 minutes online or by phone. You will provide your name, Social Security number, date of birth, and proof that you are enrolled in an HSA-may be able to access plan. Some institutions ask for a copy of your insurance card or a letter from your employer confirming your plan type. After you open the account, you can when ready start contributing money or having your employer deposit contributions directly.

Key Takeaways

  • Your health insurance plan must be designated as HSA-may be able to access (usually called a high-deductible plan) before you can open an HSA account.
  • You can open an HSA through your insurance company, your bank, your employer's payroll system, or a dedicated HSA provider — the account works the same way regardless.
  • You will need your Social Security number and proof of enrollment in an HSA-may be able to access plan, which takes about 15 minutes to provide online.
  • Contributions can come from your paycheck (pre-tax, which saves you money on taxes), from you directly, or from your employer as part of compensation.

Where to open an HSA account

Your insurance company is often the easiest starting point because they already have your enrollment information and can verify your plan may be able to access when ready. Most major insurers — including UnitedHealthcare, Aetna, Cigna, and Anthem — offer HSA accounts directly to their members. You can usually open one through their website or by calling the number on your insurance card.

If your insurance company does not offer an HSA, or if you want more investment options or lower fees, you can open an account with a bank or dedicated HSA provider. Common options include Fidelity, Lively, HealthEquity, and Optum Bank. These institutions often have lower fees than insurance companies and allow you to invest your HSA balance in stocks and bonds rather than keeping it in a savings account earning minimal interest. Your employer may also have a preferred HSA provider — check with your benefits department, because some employers subsidize fees or offer matching contributions through a specific provider.

What documents you need before you start

Gather these items before you open an account: your Social Security number, a government-issued ID, and proof that you are enrolled in an HSA-may be able to access plan. The proof of enrollment is usually your insurance card, a benefits summary from your employer, or a letter from your insurance company stating your plan type. If you are self-employed or buying insurance on your own, your insurance company's confirmation email or your policy documents work as proof.

If you are opening an HSA through your employer's payroll system, your employer's benefits administrator will already have this information and you may only need to confirm your choice during open enrollment or when you first become may be able to access. If you are opening an account outside your employer's system, have your insurance card handy when you start the process.

How to contribute money to your HSA

There are three ways to put money into an HSA: through payroll deduction, by depositing money yourself, or through employer contributions. Payroll deduction is the most common and the most tax-efficient. When you contribute through your paycheck, the money comes out before taxes are calculated, which means you pay less in federal income tax, Social Security tax, and Medicare tax. If you earn $50,000 a year and contribute $3,000 to your HSA through payroll, you only pay income tax on $47,000.

To set up payroll deduction, contact your employer's benefits or payroll department and ask them to deduct a specific amount from each paycheck and deposit it into your HSA. You will need to tell them the name of your HSA provider and your account number. Your employer will handle the rest. You can change the amount or stop contributions at any time by notifying payroll.

If your employer does not offer payroll deduction, or if you want to contribute additional money beyond what you deduct from your paycheck, you can deposit money directly into your HSA account. Log into your HSA provider's website or app and transfer money from your bank account, the same way you would transfer money between any two bank accounts. You can also mail a check to your HSA provider, though this is slower. Direct deposits take one to three business days.

Some employers contribute money to their employees' HSAs as part of compensation — this is called an employer contribution. If your employer does this, the money appears in your account automatically and you do not have to do anything. Check your benefits summary or ask your benefits department whether your employer makes contributions and how much.

Understanding contribution limits and important date

The amount you can contribute to an HSA each year is set by federal law and changes annually. For 2024, the limit is $4,150 if you have individual coverage or $8,300 if you have family coverage. These limits include contributions from you, your employer, and anyone else who contributes on your behalf — they all count toward the same total. Your HSA provider will track your contributions and prevent you from exceeding the limit.

You can contribute to your HSA anytime during the year, but there is a important date for contributions that count toward the previous year's taxes. You have until April 15 of the following year to contribute money that counts as a deduction on your prior-year tax return. For example, money you contribute by April 15, 2025 can count as a 2024 contribution. After April 15, any contributions you make count toward the current year's limit.

If you contribute more than the annual limit, you will owe taxes and a 20 percent penalty on the excess amount. Your HSA provider should warn you before you exceed the limit, but it is your responsibility to track your total contributions across all sources.

What happens after you open your account

Once your account is open and funded, you can use your HSA debit card (if your provider issues one) to pay for may have access to medical expenses at the pharmacy, doctor's office, or hospital. may have access to expenses include copays, coinsurance, deductibles, prescription medications, dental work, vision care, and many other health-related costs. You can also withdraw money and reimburse yourself later — you do not have to spend the money when ready.

Keep receipts for all medical expenses you pay with HSA money. If you are audited by the IRS, you may need to prove that the money you withdrew was spent on may have access to expenses. The IRS does not require you to submit receipts when you withdraw money, but you must be able to produce them if asked.

Your HSA balance rolls over from year to year — unlike a flexible spending account (FSA), you do not lose money you do not spend. If you have $2,000 in your HSA on December 31 and you do not spend it, that $2,000 stays in your account and earns interest or investment returns. This is why an HSA can become a long-term savings tool for retirement health expenses.

Choosing between a savings account and investments

When you open an HSA, your provider will ask whether you want to keep your balance in a savings account or invest it in stocks and bonds. A savings account is safer — your money earns a small amount of interest and you cannot lose it. An investment account offers the potential for higher returns over time, but your balance can go down if the market declines.

Many HSA providers let you split your balance: keep some money in savings for near-term medical expenses and invest the rest for long-term growth. If you are young and healthy and do not expect to use your HSA money soon, investing can help your balance grow faster. If you plan to use the money within the next few years, a savings account is usually the safer choice.
