Whether Your HSA Earns Interest and How to Maximize It

Most HSAs earn interest, but the rate depends on how your account is structured and where you keep the money

A Health Savings Account can function as either a savings account or an investment account, and that choice determines whether you earn interest. If your HSA is set up as a savings account with a bank or credit union, it will earn interest at whatever rate that institution offers — typically between 0.01% and 5.35% annually, depending on current market conditions and the specific provider. If your HSA is invested in mutual funds, stocks, or other securities through an investment platform, you earn returns based on how those investments perform, not interest.

The catch is that many HSA providers automatically hold your money in a non-interest-bearing cash account unless you actively move it into an interest-bearing savings account or investment option. This means your balance could be earning nothing while you wait to use it for medical expenses. Understanding your account structure and the options your provider offers is the first step to making your HSA work harder for you.

Key Takeaways

• HSAs held in savings accounts at banks or credit unions earn interest, but rates vary widely and many providers offer less than 1% annually.
• Money in a non-interest-bearing cash holding account at your HSA provider earns nothing, even though you could move it to earn interest elsewhere.
• Some HSA providers offer both a savings option and an investment option, so you can keep emergency medical funds in savings and invest the rest for long-term growth.
• You can transfer your HSA to a different provider if your current one offers poor interest rates or limited investment options.
• Interest earned inside an HSA is tax-free as long as you use the money for may have access to medical expenses eventually.

How interest rates work across different HSA providers

HSA providers fall into three categories: banks, credit unions, and investment platforms. Banks and credit unions that offer HSAs typically pay interest on the full balance, but the rate is set by the institution and changes with market conditions. As of 2024, some banks offer rates between 4% and 5.35% on HSA savings accounts, while others offer less than 0.5%. Credit unions sometimes offer higher rates to members, but you must be may be able to access to join the credit union first.

Investment platforms that administer HSAs — such as Fidelity, Vanguard, and Lively — often hold your cash in a money market fund or sweep account that earns a small amount, typically 0.01% to 1%. The real opportunity with these providers is the ability to invest in mutual funds or individual securities, where your returns depend on market performance rather than a fixed interest rate. Some platforms let you keep a portion in cash and invest the rest, which is useful if you need quick access to money for near-term medical bills.

Your employer's HSA plan may use any of these providers, and you have limited choice if you want to stay in the employer plan. However, you can roll over your HSA to a different provider at any time, which is worth considering if your current provider charges high fees or offers poor interest rates.

The difference between interest-bearing and non-interest-bearing accounts

When you open an HSA, the default account structure is often a non-interest-bearing cash account. This means your balance sits idle and earns nothing, even though the money is yours to keep. The provider holds it in reserve for you to spend on medical expenses, but they do not pay you for the use of that money. This is common with HSA administrators that focus on claims processing rather than wealth management.

An interest-bearing account, by contrast, pays you a percentage of your balance each month or quarter. The interest accrues and becomes part of your HSA balance, which you can then spend on medical expenses or leave to grow. The difference compounds over time: a $5,000 balance earning 4% annually grows to $5,200 in one year, while the same balance in a non-interest-bearing account stays at $5,000.

To find out which type of account you have, log into your HSA provider's website or call their customer service line and ask whether your cash balance earns interest. If it does not, ask whether they offer an interest-bearing savings option or a sweep account that automatically moves idle cash into a money market fund. Many providers offer this at no extra cost; you just have to request it or select it during account setup.

How to move your HSA to earn more interest

If your current HSA provider offers low or no interest, you have two options: request a higher-yield account within the same provider, or transfer your HSA to a different provider. Requesting an account change is faster and requires no paperwork. Log into your account, look for account settings or investment options, and select a savings or money market option if one is available. Some providers charge a small monthly fee for investment accounts, so check the fee schedule before switching.

Transferring to a new provider is called a trustee-to-trustee transfer, and it is tax-free as long as the money goes directly from one HSA custodian to another. You do not touch the money yourself, and there is no tax consequence. The process typically takes one to two weeks. Contact the new provider first and ask them to initiate the transfer; they will request your account information from your current provider and handle the paperwork. You will need to provide your current HSA account number and the provider's contact details.

Before you transfer, compare the interest rates and fees at several providers. High-yield savings accounts at online banks sometimes offer 4% to 5% on HSA balances, while investment platforms may offer lower interest on cash but better investment options if you want to grow your balance over many years. The best choice depends on whether you plan to use your HSA soon or let it grow as a retirement savings tool.

Tax treatment of interest earned in an HSA

Interest earned inside an HSA is tax-free, which is one of the major advantages of using an HSA as a long-term savings vehicle. Unlike a regular savings account, where you pay income tax on the interest you earn, HSA interest is never taxed as long as you eventually use the money for may have access to medical expenses. This applies whether you earn interest in a savings account or investment returns from mutual funds.

The tax-free treatment applies only to the interest itself, not to withdrawals. When you withdraw money from your HSA to pay for a may have access to medical expense, the withdrawal is not taxed. The interest you earned on that money is also not taxed. However, if you withdraw money for a non-medical purpose before age 65, you owe income tax on the withdrawal plus a 20% penalty. After age 65, you can withdraw money for any reason without the penalty, though you still owe income tax on non-medical withdrawals.

Interest rates and fees to compare when choosing a provider

When comparing HSA providers, look at three numbers: the interest rate on savings, the investment options available, and the annual fees. A provider that offers 4.5% interest on a $5,000 balance earns you $225 per year, but if they charge a $120 annual fee, your net gain is only $105. A provider with 1% interest and no fees earns you $50 per year on the same balance. The math changes depending on your account size and how long you plan to keep the money in the account.

Some providers waive fees if you maintain a minimum balance, typically $2,500 to $10,000. Others charge per transaction or per investment trade. A few charge monthly maintenance fees regardless of balance. Request the full fee schedule from any provider you are considering, and ask specifically about fees for transfers, withdrawals, and account maintenance. The lowest-rate provider is not always the best choice if they charge high fees that eat into your earnings.

Using HSA interest to offset medical costs over time

One strategy for maximizing your HSA is to let it grow untouched for several years while you pay medical expenses out of pocket. This allows the interest to compound and builds a larger balance. For example, if you contribute $4,150 per year (the 2024 individual coverage limit) and earn 4% interest, your balance after five years would be approximately $22,500, compared to $20,750 with no interest. That extra $1,750 came from interest alone.

This strategy works best if you have the cash flow to pay medical expenses without using your HSA. It also requires discipline — you must keep records of all may have access to medical expenses you paid out of pocket, because you can withdraw that amount from your HSA tax-free at any time, even years later. The IRS does not require you to withdraw money in the same year you incur the expense, so you can reimburse yourself decades later if you choose.

If you do not have the cash flow to pay medical expenses out of pocket, you can still benefit from HSA interest by keeping a portion of your balance in a high-yield savings account and investing the rest. This gives you quick access to money for immediate medical needs while allowing the rest to grow through investment returns.

Frequently Asked Questions

What happens to HSA interest if I do not use the money for medical expenses?

Interest earned in an HSA is tax-free only if you eventually use the money for may have access to medical expenses. If you withdraw money for a non-medical purpose before age 65, you owe income tax on the withdrawal plus a 20% penalty. After age 65, you can withdraw for any reason without the penalty, but you still owe income tax on non-medical withdrawals.

Do all HSA providers offer interest-bearing accounts?

Not all providers offer interest by default, but most offer at least one interest-bearing or investment option. Some require you to request it or select it during setup. Call your provider and ask whether your current account earns interest and what options are available to you.

Is the interest I earn in an HSA reported to the IRS?

Yes, your HSA provider will send you a Form 1099-INT if you earn more than $10 in interest during the year. However, you do not owe tax on this interest as long as you use the HSA money for may have access to medical expenses. Report the interest on your tax return, but you may be able to exclude it from taxable income if it qualifies.

Can I invest my HSA in stocks instead of keeping it in a savings account?
