Fidelity charges absolutely nothing — no monthly fee, no investment threshold, no transfer fee — while offering access to thousands of mutual funds and ETFs including Fidelity's own zero-expense-ratio index funds.

✓Access to zero-expense-ratio index funds (e.g., FZROX at 0.00%)
✓Competitive cash yield on uninvested balances

Cons

✗Not available as employer-sponsored plan for most small businesses
✗Investment research tools less specialized for HSA planning than dedicated HSA platforms

2B+Best for Employer PlansOptum Bank HSA

Optum Bank is one of the largest HSA custodians in the US and the default provider for millions of employer-sponsored plans, which means your HR contribution may land here automatically. The $2.75/month fee ($33/year) is waived when your balance stays above $3,000, and you get access to a curated mutual fund menu once you clear that threshold. The mobile app integrates with UnitedHealth claim data if you are on a UHC plan, which cuts down on manual receipt entry.

Pros

✓Seamless integration with UnitedHealthcare insurance claims
✓Fee waived at $3,000 balance — realistic for most long-term savers

How to choose the right HSA

Not all HSAs are created equal. Custodian fees, minimum balances before investing, and fund choices vary wildly — and a $3/month fee sounds trivial until you realize it devours $36 a year in interest before you've grown a cent.

Fees and account minimums

Monthly maintenance fees range from $0 to nearly $4. Over a decade, a $3.95/month fee costs you roughly $500 before compounding — money that could have been invested. Look for accounts that waive fees when you maintain a minimum balance, and check whether that minimum is held in cash (earning little) or can sit in your investment portfolio.

Investment options

The real HSA advantage is triple-tax savings: contributions go in pre-tax, growth is tax-free, and qualified withdrawals are tax-free. That only pays off if you can invest beyond a low-yield savings balance. Check the fund menu for low-cost index funds — look for expense ratios under 0.10% — and confirm how much cash you must hold before investing.

Interest rates on uninvested cash

If you use your HSA as a pass-through for current medical expenses rather than a long-term investment account, the APY on your cash balance matters. Rates fluctuate with the Fed, but comparing base rates across providers reveals meaningful differences — some custodians pay almost nothing while others pass along competitive yields.

FDIC or NCUA insurance

Your cash balance should be FDIC-insured up to $250,000. Most bank-based HSAs meet this standard, but confirm it, especially with newer fintech-style providers. Investments held in brokerage accounts are covered by SIPC, not FDIC, which protects against custodian failure — not market losses.

Integration with your health plan and employer

If your employer contributes to your HSA, your HR department may require a specific custodian. Check before opening an outside account — you can always do a trustee-to-trustee transfer later, but the process takes weeks and may incur a transfer fee. Also verify the provider's mobile app and debit card usability if you plan to pay medical bills directly.

Bottom line

Fidelity and Lively stand out for fee-conscious savers who want real investment access without sacrificing cash yield. If your employer uses Optum or HealthEquity, the locked-in custodian is fine for contribution purposes — just consider a trustee-to-trustee transfer to a free provider once your balance grows. Further HSA is a reasonable middle ground if you want dedicated HSA-focused customer support and can tolerate a modest monthly fee.

Whichever account you choose, the worst move is keeping your HSA parked in the default cash position. Even modest monthly contributions invested in a low-cost S&P 500 index fund grow significantly over a 20-year horizon — and every dollar of qualified medical expenses you pay from the HSA is effectively a tax-free dollar spent.

Frequently asked questions

Can I have an HSA if my employer already contributes to one?▼

Yes. Employer contributions count toward your annual IRS contribution limit ($4,300 for self-only, $8,550 for family in 2026), but you are free to open a separate HSA at a provider of your choice and do a trustee-to-trustee transfer from your employer-sponsored account to consolidate funds.

What happens to my HSA if I switch to a non-HDHP health plan?▼

You can no longer make new contributions once you are no longer enrolled in a qualifying high-deductible health plan, but the existing balance remains yours forever. You can still invest it, spend it on qualified medical expenses tax-free, or after age 65 withdraw it for any reason (taxed as ordinary income, like a traditional IRA).

Is it worth investing my HSA rather than spending it on current medical bills?▼

If you can afford to pay current medical expenses out of pocket, keeping receipts and reimbursing yourself years later is a powerful strategy — sometimes called the HSA reimbursement hack. Your invested balance compounds tax-free, and there is no deadline to claim reimbursement, so a bill from 2026 can be reimbursed in 2036.

What counts as a qualified medical expense?▼

The IRS list is broad: doctor visits, prescriptions, dental work, vision care, mental health therapy, and even certain over-the-counter items like menstrual products and sunscreen qualify. Non-qualified withdrawals before age 65 trigger income tax plus a 20% penalty, so keep records.

Can I use my HSA to pay Medicare premiums?▼

Yes, once you are enrolled in Medicare (typically at 65), you can use your HSA to pay Medicare Part B, Part D, and Medicare Advantage premiums tax-free. You cannot use it to pay Medigap supplement premiums, however.
