Best HSA Providers in 2026: Fidelity vs Lively vs HealthEquity vs Optum

A health savings account is the only account in the US tax code with a triple tax advantage — money goes in pre-tax, grows tax-free, and comes out tax-free for qualified medical expenses. But that advantage gets quietly eroded if your HSA sits with a provider charging monthly fees, investment fees, and fund expenses stacked on top of each other. In 2026, the gap between the best and worst HSA providers can cost you tens of thousands of dollars over a working lifetime. Here's how Fidelity, Lively, HealthEquity, and Optum Bank actually stack up — and what to do if your employer picked one of the expensive ones.

First, the 2026 numbers you need to know

Before comparing providers, make sure you're eligible and know your ceiling. To contribute to an HSA in 2026, you must be covered by a qualifying high-deductible health plan (HDHP). For 2026, that means a plan with a minimum deductible of $1,700 for self-only coverage or $3,400 for family coverage, with out-of-pocket maximums capped at $8,500 self-only and $17,000 family.

If your plan qualifies, the 2026 contribution limits are:

• $4,400 for self-only HDHP coverage
• $8,750 for family HDHP coverage
• An extra $1,000 catch-up contribution if you're 55 or older

Those limits include anything your employer kicks in. If your company contributes $1,000 to your family-coverage HSA, you can add up to $7,750 yourself. To see what those contributions are actually worth in tax savings at your income level, run your numbers through our HSA tax savings calculator.

One quick caveat on the “triple tax advantage”: it's a federal description. A couple of states don't play along — California and New Jersey tax HSA contributions and earnings at the state level. If you live in either, the math changes somewhat (the accounts are still usually worth it), and our guide to state HSA tax treatment walks through exactly how.

The four providers at a glance

These four dominate the US HSA market for different reasons. Fidelity and Lively win on the merits — people actively choose them. HealthEquity and Optum Bank win on distribution — employers choose them, and employees inherit the choice. That distinction explains almost everything in the table below.

Fidelity: the gold standard for self-directed HSAs

Fidelity's HSA is widely regarded as the best retail HSA in the country, and the reasons are boringly simple: it doesn't charge you anything, and it doesn't restrict you.

There's no monthly maintenance fee. No minimum balance. No required cash holding before you can invest — you can put your first dollar into the market the day it lands. You get a full brokerage window, which means access to stocks, ETFs, and Fidelity's famously cheap index funds, including its zero-expense-ratio funds. Fractional shares are supported, so even small contributions get fully invested instead of sitting as leftover cash.

The cash side is competitive too — uninvested balances earn interest at rates that have consistently beaten the near-zero rates most HSA custodians pay. And because it's Fidelity, your HSA sits next to your 401(k), IRA, and brokerage in one app, with customer service that handles complex questions (transfers, excess contribution corrections, beneficiary issues) without bouncing you between departments.

Weaknesses? Few. The interface is a general-purpose brokerage platform, so it's less “health-spending friendly” than purpose-built HSA apps — no slick receipt-vault front and center, though documentation features exist. And if your employer doesn't offer Fidelity, your payroll contributions will land somewhere else first (more on fixing that below).

Lively: the strongest UX, and a real Fidelity rival

Lively is a fintech built specifically around HSAs, and it shows. The app and web experience are the best in the category: clean contribution tracking, a receipt vault for documenting expenses you plan to reimburse years later, clear visibility into your eligibility and limits, and genuinely fast, human customer support.

For individuals, there's no monthly fee. For investing, Lively gives you two doors:

• Schwab self-directed brokerage: a full brokerage window through Charles Schwab with no added access fee for the self-directed route — you pick your own ETFs and index funds.
• Devenir guided portfolio: a curated, hands-off option for people who don't want to pick funds, at roughly a 0.50% annual fee. Convenient, but that fee compounds — most readers are better off self-directing into one or two broad index ETFs.

The fair comparison with Fidelity: functionally close to a tie for a self-directed investor. Fidelity edges ahead on fractional shares, in-house zero-fee index funds, and having everything under one institutional roof. Lively edges ahead on the day-to-day experience of actually using an HSA — tracking expenses, storing receipts, understanding your status. Neither will nickel-and-dime you, which is the bar the next two providers fail to clear.

HealthEquity: the employer giant

HealthEquity is the largest dedicated HSA custodian in the country by number of accounts, and almost nobody chose it. It wins corporate benefits contracts, so millions of employees get a HealthEquity account opened for them during open enrollment.

As a captive experience, it's serviceable. The platform handles payroll contributions, debit cards, and claims integration with employer health plans smoothly. But the economics tilt against the account holder:

• Monthly admin fee: often in the $3–$4 range. Many employers pay it on your behalf while you're employed — the fee frequently appears after you leave the job, which is exactly when people forget about old HSAs.
• Investment thresholds: depending on the plan, you may need to keep a minimum (commonly $500–$1,000 or more) parked in cash earning very little before you can invest the rest.
• Expense layers: the investment menu is a curated list of mutual funds, and between fund expense ratios and plan-level investment administration fees, the all-in cost of investing is meaningfully higher than holding an index fund at Fidelity or Schwab.

A $4 monthly fee sounds trivial. On a $2,000 balance, it's a 2.4% annual drag — worse than most actively managed mutual funds people rightly avoid. Small fees on small balances are how HSA custodians make their money.

Optum Bank: the default you probably didn't pick

Optum Bank is owned by UnitedHealth Group, which makes it the path of least resistance for the enormous number of employers using UnitedHealthcare plans. Like HealthEquity, it's a distribution-driven product.

The typical fee structure: a monthly maintenance fee around $2.75–$3, waived once your balance crosses a threshold that usually sits somewhere between $3,000 and $5,000 depending on the plan. To invest, you generally need to keep about $2,000 in the cash account — money earning a token interest rate while inflation eats it. The investment side carries its own fees on top of fund expense ratios.

The platform itself is fine — the app works, the debit card works, claims integration with UnitedHealthcare plans is genuinely convenient. But “fine, with fees” loses to “excellent, free” every time the choice is actually yours.

The employer-HSA problem — and the transfer that fixes it

Here's the structural issue: your employer picks your HSA provider, but the account belongs to you. Unlike a 401(k), an HSA is an individual account in your name. You are free to move the money whenever you like, while still employed, with no tax consequences if you do it correctly.

The smart pattern, used by a lot of HSA optimizers:

1. Keep contributing through payroll at your employer's provider (Optum, HealthEquity, whoever). Payroll HSA contributions skip FICA taxes — an extra 7.65% saving you cannot get by contributing directly from your bank account. Don't give that up.
2. Open a Fidelity or Lively HSA on your own. It's free and takes minutes.
3. Periodically sweep the balance from the employer HSA to your chosen HSA via a trustee-to-trustee transfer.

That last step has an important distinction, covered in IRS Publication 969. There are two ways to move HSA money:

• Trustee-to-trustee transfer: the receiving provider pulls the funds directly from the old custodian. You never touch the money. Unlimited — you can do this monthly, quarterly, whenever. No tax reporting headache.
• 60-day rollover: the old custodian sends you a check, and you have 60 days to deposit it into the new HSA. Per IRS Pub. 969, you can only do this once per 12-month period, and if you miss the 60-day window the entire amount becomes taxable income plus a 20% penalty if you're under 65.

Always choose the trustee-to-trustee transfer. Initiate it from the receiving side (Fidelity and Lively both have simple online transfer flows that do the chasing for you). Two things to check first: whether your old provider charges an account-closure or outbound-transfer fee (commonly $20–$25 at employer-market custodians) and whether you need to sell investments back to cash before the transfer — many custodians only transfer cash. The closure fee stings once; the monthly fees sting forever.

One sequencing tip: if you sweep periodically rather than closing the old account, you keep payroll contributions (and the FICA break) flowing while your long-term balance compounds fee-free at Fidelity or Lively.

Investing your HSA: where the real money is made

The biggest HSA mistake isn't picking the wrong provider — it's leaving the whole balance in cash. An HSA invested in a broad index fund for 20–30 years, with medical receipts saved for later tax-free reimbursement, functions as a super-charged retirement account: better tax treatment than a 401(k) or Roth IRA for medical spending, which is one of the largest expenses of retirement.

Provider choice determines how easy that is:

• Fidelity: invest from the first dollar, fractional shares, total-market index funds with expense ratios at or near zero. The ceiling and the floor of the market.
• Lively: invest from the first dollar via Schwab; pick any low-cost ETF. Devenir route available if you want it managed, at ~0.50%.
• HealthEquity: clear the cash threshold first, then choose from a fund menu with extra fee layers. Investable, just more expensive.
• Optum: keep ~$2,000 in cash, invest the rest from a curated menu with platform fees. Workable as a holding pattern, not a destination.

A note for spenders rather than savers: if you genuinely use your HSA as a checking account for this year's medical bills, fees and investment menus matter less — debit-card reliability and claims integration matter more, and the employer defaults are tolerable. But if you have any capacity to pay medical bills out of pocket and let the HSA ride, the long game belongs to the no-fee providers. (And if you're still deciding between account types entirely, our HSA vs FSA comparison covers why the HSA's rollover-forever design beats the FSA's use-it-or-lose-it rule for anyone eligible for both.)

Recommendation matrix

Picking the right HSA provider

For 2026, Fidelity is the best HSA provider for most people: zero fees, zero minimums, fractional shares, and the cheapest index funds available anywhere. Lively is a close second and wins outright if you value a purpose-built HSA experience with receipt tracking and standout support — just take the free Schwab brokerage route rather than the managed option. HealthEquity and Optum Bank are where most Americans' HSA money lives because employers put it there, not because it belongs there; both layer monthly fees, cash thresholds, and investment charges that quietly erode the account's famous triple tax advantage. The fix is simple and entirely within your control: keep contributing through payroll to capture the FICA savings, then sweep your balance to Fidelity or Lively with unlimited trustee-to-trustee transfers under IRS Pub. 969. Max what you can toward the $4,400 self-only or $8,750 family limit, invest anything you won't spend this year, and let the only triple-tax-advantaged account in the code do its compounding somewhere that isn't charging you for the privilege.
