Does Vanguard Actually Offer an HSA?

Does Vanguard Offer an HSA Account Directly to Individuals?

The short answer: not exactly. Vanguard does not administer HSAs directly to retail investors. Instead, it partners with third-party HSA custodians, most notably HealthEquity, which offer access to Vanguard funds inside their platforms. That structural layer matters because you pay both the custodian's administrative fee and the underlying fund expense ratios. The cost advantage Vanguard is famous for gets partially absorbed before it reaches your account.

That distinction doesn't disqualify the Vanguard HSA route. For high earners already running Vanguard portfolios who want consistency across accounts, the familiarity and fund quality still make it a reasonable choice. But the all-in cost picture is more complicated than "Vanguard equals cheap," and anyone at the $5M+ level should run the actual numbers before assuming this is the lowest-cost path.

The more interesting question for this audience isn't which custodian logo sits on the account. It's whether you're using the HSA correctly at all.

What Are the HSA Contribution Limits for 2024 and 2025?

The IRS adjusts HSA limits annually for inflation. According to IRS Revenue Procedure 2023-23, the 2024 limits are $4,150 for self-only coverage and $8,300 for family coverage under a qualifying high-deductible health plan (HDHP). For 2025, IRS Revenue Procedure 2024-25 sets those limits at $4,300 and $8,550 respectively. The catch-up contribution for individuals age 55 and older remains $1,000 in both years.

To qualify for any HSA contribution, your HDHP must meet IRS minimum deductible thresholds. For 2025, that means a minimum deductible of $1,650 for self-only coverage or $3,300 for family coverage, with out-of-pocket maximums capped at $8,300 and $16,600 respectively.

You cannot contribute to an HSA if you are enrolled in Medicare, covered by a non-HDHP plan (including a spouse's plan), or claimed as a dependent on someone else's return.

One planning note for early retirees: if you claim Social Security before age 65, the Social Security Administration automatically enrolls you in Medicare Part A, and that enrollment can apply retroactively up to six months. An inadvertent HSA contribution during that retroactive window triggers a 6% excise tax. If you're planning to keep contributing to an HSA past age 64, coordinate your Medicare enrollment timing carefully with your tax attorney before making any contributions.

Is an HSA Worth It If You Have High Net Worth and Can Afford Medical Expenses Out of Pocket?

This is where the standard retail framing completely misses the point for this audience.

Most HSA content is written for someone who needs help covering a $3,000 deductible. For a $5M+ net worth individual, the deductible is noise. The reason to run a Vanguard HSA has nothing to do with covering medical bills and everything to do with what financial planners call the "stealth IRA" strategy.

Here's the structure: you contribute the annual maximum to your HSA, pay every qualified medical expense out of pocket from your taxable account, save every receipt indefinitely (the IRS imposes no deadline on reimbursement), and let the HSA balance compound in equities untouched. Decades later, you reimburse yourself tax-free for all those accumulated out-of-pocket expenses, effectively pulling money out of the HSA with zero tax consequence.

The math is not trivial. At $8,550 per year (2025 family limit) compounding at 7% annually over 20 years, you accumulate over $370,000 in additional tax-free assets. That's on top of your 401(k), backdoor Roth, and mega-backdoor Roth contributions. There's no income limit restricting HSA contributions the way there is for direct Roth IRA contributions.

Research published in the Journal of Financial Planning supports this approach for high-income earners: paying current medical expenses from taxable funds while keeping HSA assets fully invested maximizes long-term tax-free compounding. The administrative burden is real but manageable. You need a receipt-tracking system that will survive 20 years. A dedicated folder in your document management system, scanned and backed up, handles it.

The one genuine objection is that most HSA holders don't invest their balances at all. EBRI research consistently shows that only a small minority of HSA account holders move beyond the cash default, leaving the majority of HSA assets earning minimal returns. If you're reading this, you're not that person. But it's worth confirming that your specific custodian actually allows full equity investment and doesn't impose a cash minimum before investing kicks in.

Is Fidelity or Vanguard Better for HSA Investing?

For most high earners, Fidelity wins on cost structure. That's not a knock on Vanguard's investment quality. It's a structural reality.

Fidelity administers its own HSA directly, with zero account fees, no minimum balance requirement to begin investing, and access to Fidelity ZERO index funds carrying a 0.00% expense ratio. Vanguard-affiliated HSAs, by contrast, route through third-party custodians like HealthEquity, which charge their own administrative fees on top of Vanguard fund expense ratios. Vanguard's Admiral Shares are excellent, but even a 0.04% expense ratio on VTSAX plus a custodian fee of $3 to $5 per month creates a higher all-in cost than Fidelity's zero-fee structure.

Morningstar's annual HSA landscape report has consistently given Fidelity top marks for its no-fee, no-minimum structure and access to low-cost index funds. Lively, another strong option, also charges no account fees and allows direct investment in Vanguard ETFs through a TD Ameritrade brokerage link.

HSA Provider Comparison: Vanguard-Affiliated vs. Fidelity vs. Lively vs. Optum

Fees subject to change. Verify current fee schedules directly with each provider.

The honest assessment: if you're choosing a Vanguard HSA specifically because you believe Vanguard's cost advantage carries over from its brokerage accounts, verify the custodian's fee schedule first. For a $100,000 HSA balance, even a $36 annual admin fee represents a 0.036% drag that erases part of the fund-level cost advantage. At scale, Fidelity's zero-fee structure is genuinely superior for pure cost minimization.

Where Vanguard-affiliated HSAs still make sense: if your employer's benefits platform defaults to HealthEquity with Vanguard funds, the friction of maintaining a separate HSA elsewhere may not be worth the marginal cost savings. Consolidation has real value.

Can You Invest Your HSA in Vanguard Index Funds?

Yes, through the custodian arrangement described above. HealthEquity, one of the largest HSA custodians in the U.S. and Vanguard's primary HSA partner, offers a curated menu of Vanguard funds for invested balances. Common options include:

• Vanguard Total Stock Market Index Fund (VTSAX/VTI): Broad U.S. equity exposure, 0.03% expense ratio
• Vanguard Total International Stock Index Fund (VTIAX/VXUS): International diversification, 0.07% expense ratio
• Vanguard Total Bond Market Index Fund (VBTLX/BND): Investment-grade U.S. bond exposure, 0.03% expense ratio
• Vanguard Target Retirement Funds: Automatic glide path for hands-off allocation

The specific fund menu varies by custodian and employer plan. If you're accessing a Vanguard-affiliated HSA through an employer benefits platform, the available fund list may be narrower than what HealthEquity offers in its direct retail HSA.

For the stealth IRA strategy described above, the asset allocation decision is straightforward: invest 100% in equities if your time horizon is 15 or more years and you can cover any near-term medical expenses from other funds. The sequence-of-returns risk that applies to a spending account doesn't apply when you're treating the HSA as a long-term investment vehicle with decades before you touch it.

If you anticipate needing HSA funds within three to five years for actual medical expenses, hold enough in the cash or stable value option to cover your expected HDHP out-of-pocket maximum. Invest the rest.

The HSA as a Stealth IRA: The Strategy Most High Earners Miss

At the FatFIRE level, you've likely already maxed your 401(k), executed the backdoor Roth, and possibly run the mega-backdoor Roth through an after-tax 401(k). The HSA is the next layer, and it's one of the few remaining tax-free compounding vehicles with no income limit restriction.

The mechanics, restated clearly:

1. Confirm HDHP eligibility and contribute the annual maximum ($8,550 family, $4,300 self-only for 2025).
2. Pay every qualified medical expense out of pocket from your taxable account or checking.
3. Save every receipt, permanently. Digital copies with a clear naming convention work fine.
4. Invest 100% of the HSA balance in equities.
5. In retirement, submit accumulated receipts for tax-free reimbursement, or use the funds directly for Medicare premiums, long-term care costs, and other qualified medical expenses.

Fidelity estimates that a 65-year-old couple retiring today may need approximately $315,000 in after-tax savings to cover healthcare expenses in retirement. An HSA that has compounded for 20 years covers a substantial portion of that figure with zero tax cost on withdrawal.

The strategy pairs naturally with maximizing HSA funds in retirement and complements self-employed retirement planning options if you're running a business entity. For those coordinating across multiple Vanguard accounts, cash management solutions at Vanguard can simplify the out-of-pocket payment workflow.

HSA vs. Other Tax-Advantaged Accounts: Strategic Comparison for High Earners

HSA medical withdrawals are completely tax-free. Non-medical withdrawals after 65 are taxed as ordinary income, equivalent to a traditional IRA.

What Happens to Your HSA at Age 65?

The penalty structure changes entirely. Before age 65, non-qualified withdrawals from an HSA face ordinary income tax plus a 20% penalty. After 65, per IRC Section 223, the 20% penalty disappears. Non-qualified withdrawals are taxed as ordinary income, identical to a traditional IRA distribution.

This reframes the risk calculus. The downside of accumulating more in your HSA than you spend on medical expenses isn't a punitive outcome. It's simply a traditional IRA equivalent, with the added advantage that any medical spending remains completely tax-free. You cannot lose by over-saving in an HSA if you're past 65.

The practical implication for dynamic spending strategies for retirement: sequence your HSA withdrawals to cover actual medical expenses first, then treat the remainder as a traditional IRA bucket for living expenses. This maximizes the tax-free advantage on the medical portion while preserving flexibility on the rest.

Medicare premiums, including Part B, Part D, and Medicare Advantage premiums, qualify as HSA-eligible expenses after 65. Long-term care insurance premiums qualify up to IRS age-based limits. These categories alone can absorb substantial HSA balances tax-free.

How Does an HSA Fit Into an Estate Plan for High-Income Earners?

Bluntly: it doesn't, at least not as a wealth transfer vehicle. This is the most important limitation that standard HSA coverage ignores.

When a non-spouse inherits an HSA, the entire account balance becomes taxable income to the beneficiary in the year of the account holder's death. No 10-year distribution window like inherited IRAs under the SECURE Act. No stepped-up basis. The full balance hits as ordinary income immediately.

For a $5M+ estate, this inheritance tax treatment makes the HSA a poor vehicle for intergenerational wealth transfer. A surviving spouse inherits an HSA without tax consequence and can treat it as their own. Everyone else faces an immediate tax bill.

The strategic implication is clear: spend down your HSA in retirement rather than passing it on. Prioritize HSA funds for your own medical expenses before drawing from IRAs or taxable accounts. This preserves the tax-free advantage during your lifetime and avoids handing a concentrated taxable event to your heirs.

For estate planning coordination, trust account structures for wealth planning and donor-advised funds for charitable giving are far more efficient vehicles for wealth transfer than an HSA. If your estate plan involves significant charitable intent, a donor-advised fund funded from taxable assets while you spend HSA funds on personal medical costs is a more tax-efficient sequence than the reverse.

Those working with ultra-high net worth investment services or flagship services for affluent investors should confirm that their advisor has explicitly modeled HSA drawdown sequencing in the context of the full estate plan.

Opening a Vanguard HSA: The Actual Process

Because Vanguard doesn't administer HSAs directly, "opening a Vanguard HSA" means opening an account with a Vanguard-affiliated custodian. The most common path:

Through an employer: If your employer's benefits platform uses HealthEquity with Vanguard funds, enrollment happens during open enrollment. Contributions can be made pre-tax through payroll, which also avoids FICA taxes on the contributed amount, a meaningful advantage over contributing post-tax and deducting on your return.

Direct retail account: HealthEquity offers individual HSA accounts directly. You'll need to verify HDHP enrollment, provide your plan documentation, and confirm you meet all IRS eligibility requirements.

The setup steps for a direct retail account:

1. Confirm your health plan qualifies as an HDHP under current IRS thresholds.
2. Open an account directly with HealthEquity (or your preferred Vanguard-affiliated custodian).
3. Provide HDHP documentation and personal identification.
4. Select your investment allocation from the available Vanguard fund menu.
5. Set up contribution transfers, either from payroll (if employer-sponsored) or direct bank transfer.
6. Establish your receipt-tracking system before your first out-of-pocket medical expense.

The last step is not optional if you're running the stealth IRA strategy. A receipt you can't produce 15 years from now is a receipt that can't support a tax-free reimbursement.

For those coordinating HSA contributions with other retirement vehicles, review 401(k) withdrawal rules and options to model the full tax picture across accounts. And confirm the custodian's treatment of FDIC insurance coverage at Vanguard for any cash balance you maintain in the account before investing.

When a Vanguard HSA Makes Sense (and When It Doesn't)

The case for a Vanguard-affiliated HSA is strongest when:

• Your employer's benefits platform already routes through HealthEquity with Vanguard funds, making the custodian choice frictionless.
• You're already a Vanguard investor and value account consolidation over marginal cost differences.
• You plan to run the stealth IRA strategy and want the fund quality and index discipline Vanguard is known for.

The case weakens when:

• You're choosing a provider from scratch with no employer constraint. Fidelity's zero-fee, zero-minimum structure has a genuine cost advantage at every balance level.
• You need frequent debit card access for ongoing medical expenses. The investment-focused structure of Vanguard-affiliated HSAs adds friction for routine spending.
• Your time horizon is short. If you anticipate significant medical expenses within three to five years, the investment vehicle argument matters less than liquidity and ease of reimbursement.

The honest competitive picture: Fidelity wins on cost for most independent comparisons. Vanguard wins on familiarity for existing Vanguard clients and on fund quality for those who specifically want Vanguard index funds inside their HSA. Lively offers a strong middle path with no fees and broad ETF access. Optum Bank, despite its scale, typically carries higher costs and more limited investment options.

For a $5M+ net worth individual, the difference in fees between top-tier providers is unlikely to be material relative to the tax savings from running the strategy correctly. Pick a provider with no cash minimums before investing, confirm the fund menu includes broad equity index options, and execute the stealth IRA strategy consistently. That decision matters far more than which logo is on the account.
