More than a million Americans hold a Bank of America Health Savings Account, and plenty of them wonder where Merrill fits in. If you have been searching for a Merrill Lynch health savings account, here is the short answer. Merrill is the investment arm of Bank of America, so the bank holds your HSA cash while Merrill helps power the investment side.
This guide explains how the account works, what it costs as of July 2026, and how to decide if it fits your health and money goals.
How a Merrill Lynch Health Savings Account Works
A Health Savings Account, or HSA, is a tax-advantaged account for medical costs. You can only open and fund one if you are enrolled in a qualified high-deductible health plan, also called an HDHP.
With Bank of America as the custodian, your contributions sit in an FDIC-insured cash account. Once your balance is large enough, you can move money into investments through the Merrill platform. Think of Bank of America as the bank and Merrill as the investing engine.
You get a Visa debit card, a mobile app, and online bill pay. The money is always yours, even if you change jobs or health plans.

Who Can Open One in 2026
To contribute to any HSA in 2026, your HDHP must meet the IRS rules. The minimum deductible is $1,700 for self-only coverage and $3,400 for a family.
Your plan's out-of-pocket maximum cannot exceed $8,500 for self-only coverage or $17,000 for family coverage. You also cannot be enrolled in Medicare or be claimed as someone else's dependent.
If you meet those rules, you can contribute up to $4,400 for self-only coverage or $8,750 for family coverage this year. People age 55 and older can add a $1,000 catch-up contribution.
The Triple Tax Advantage
An HSA is the only account that can give you three separate tax breaks. Your contributions may be tax-deductible, your money grows tax-free, and withdrawals for qualified medical costs are tax-free too.
That mix is why many savers treat an HSA as a long-term account, not just a spending wallet. If you can pay current medical bills out of pocket, your HSA dollars have more years to grow.
After age 65, you can withdraw funds for any reason and pay only regular income tax, similar to a traditional IRA. Withdrawals for non-medical costs before 65 face a 20% penalty plus income tax.
Fees and Interest You Should Know
The Bank of America HSA charges a $2.50 monthly maintenance fee for individual and family accounts, based on its published schedule. If you got the account through an employer or insurer, that fee may be lower or waived.
Cash balances earn tiered interest, from about 0.10% APY on smaller balances up to 0.45% APY on balances above $25,000, as of July 2026. Those rates are modest, which is one reason investing can matter for long-term savers.
If you want a simple everyday spending account to sit alongside your HSA, a fee-friendly option like Current Banking can help you avoid surprise charges on your regular money.

Investing Inside a Merrill Lynch Health Savings Account
Once your HSA balance passes $1,000, you can invest the amount above that threshold. Bank of America offers a lineup of around 38 mutual funds, many from low-cost families, and there are no trading fees to buy or sell them within the account.
Features include automatic investment sweeps, dividend reinvestment, and auto-rebalancing. That makes it fairly hands-off once you set it up.

If the account fits, you can open it online and set up automatic contributions. Terms and conditions apply, and investment returns are never guaranteed.
Frequently Asked Questions
Is there a separate Merrill Lynch HSA product?
Not exactly. Bank of America is the HSA custodian, and Merrill provides the investment platform behind it. When people say Merrill Lynch health savings account, they usually mean the Bank of America HSA with Merrill investing.
How much does the Bank of America HSA cost in 2026?
The standard account has a $2.50 monthly maintenance fee, based on the bank's published schedule as of July 2026. Employer or insurer plans may waive it, and there are no trading fees inside the investment account.
When can I start investing my HSA funds?
You can invest once your cash balance rises above $1,000. Any amount over that threshold can go into the mutual fund lineup, while the first $1,000 stays in the cash account.
What happens to my HSA if I leave my job?
Your HSA belongs to you, not your employer. You keep the account, the balance, and any investments, and you can keep spending on qualified medical costs even after you switch jobs or retire.
