How to Open an HSA at Vanguard and What It Covers

Vanguard offers HSA accounts, but not as a standalone product — you open one through a health plan, then move the money to Vanguard to invest it

Vanguard does not issue health savings accounts directly. Instead, Vanguard acts as the custodian — the institution that holds and invests your HSA money once you have opened the account through your health insurance plan or employer. This is how most HSAs work: your employer or insurer sets up the account with a bank or insurance company, you fund it with pre-tax money, and then you can transfer those funds to an investment provider like Vanguard if you want to invest rather than leave the money sitting in a low-interest savings account.

The practical result is that you cannot go to Vanguard's website and open an HSA from scratch. You need an HSA first — which comes from your health plan or employer — and then you can move it to Vanguard. This two-step process matters because it affects timing, fees, and what documents you need to have ready.

Key Takeaways

Vanguard holds HSAs but does not issue them; you must open an HSA through your health plan or employer first.
Once you have an HSA account number, you can request a transfer to Vanguard to invest the balance in mutual funds or other securities.
Vanguard charges a custodial fee (currently $25 per year for most HSA accounts) plus the expense ratios on any funds you choose.
The transfer process typically takes one to two weeks, and your money is not invested during that time.
You can only contribute to an HSA if you are enrolled in a high-deductible health plan (HDHP) with your insurer.

Where your HSA actually comes from

Your HSA originates with your health insurance company or your employer's benefits administrator. When you enroll in a high-deductible health plan (HDHP), the insurer or your employer typically offers an HSA as part of that enrollment. Some employers set up the HSA with a specific bank or provider; others let you choose where to open it. If you have a choice, you can select Vanguard at that point — but this is rare. Most people end up with an HSA at a bank or insurance company they did not choose.

If your employer or insurer did not offer an HSA choice, or if you have an individual health plan, you can open an HSA independently through any bank or provider that offers them. Once that account is open and has an account number, you can then move the money to Vanguard.

The key requirement: you must be enrolled in an HDHP to contribute to an HSA at all. If you switch to a different health plan that is not high-deductible, you can no longer add money to the HSA, though you can keep the account and the money already in it.

How to move an existing HSA to Vanguard

If you already have an HSA elsewhere, you can transfer it to Vanguard by requesting what is called a custodian-to-custodian transfer. You do not withdraw the money yourself; instead, the two institutions handle the move directly, and the IRS does not count it as a distribution. This is important because if you withdraw the money and deposit it yourself, you have only 60 days to complete the move or you owe taxes and penalties.

The process: contact Vanguard and ask to open an HSA. Vanguard will provide you with a transfer form. You fill it out with your current HSA account number and the name of the institution holding it, then send the form to your current HSA provider. They send the money directly to Vanguard. The whole process usually takes one to two weeks, though it can stretch to three weeks if either institution is slow to process.

During the transfer, your money sits uninvested. You cannot buy or sell investments in either account. Once the money arrives at Vanguard, you can then choose what to invest it in — Vanguard's mutual funds, ETFs, or other securities.

Vanguard HSA fees and investment options

Vanguard charges a custodial fee of $25 per year for HSA accounts (as of 2024; this can change). This is separate from the expense ratios on any funds you invest in. If you invest in Vanguard's own mutual funds, you pay the fund's expense ratio — typically 0.03% to 0.20% per year for index funds, higher for actively managed funds. If you invest in individual stocks or other securities, there are no additional fund fees, only the annual custodial fee.

Vanguard's main advantage as an HSA custodian is low-cost index funds and ETFs. If you plan to invest your HSA rather than use it for near-term medical expenses, Vanguard's fund selection and low fees make it competitive. If you want to keep the money in cash, a traditional bank HSA with a savings account might be simpler and cheaper.

You can also hold a money market fund or savings option at Vanguard while you decide what to invest in. The interest rate on these is typically lower than a dedicated HSA savings account at a bank, so if you need the money within a year or two, a bank HSA might be the better choice.

What you can and cannot do with a Vanguard HSA

An HSA at Vanguard works like any other HSA: you can withdraw money tax-free to pay for may have access to medical expenses. may have access to expenses include deductibles, copays, coinsurance, prescription drugs, dental work, vision care, and many other health costs. You cannot use HSA money for health insurance premiums (with narrow exceptions for COBRA, Medicare, or long-term care insurance), and you cannot use it for cosmetic procedures or over-the-counter drugs unless prescribed by a doctor.

You can withdraw money at any time, but if you use it for a non-may have access to expense before age 65, you owe income tax on that amount 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. This makes an HSA a powerful retirement savings tool if you do not need the money for medical expenses now.

Vanguard does not restrict what you invest in the way some HSA providers do. You have access to Vanguard's full range of mutual funds and ETFs, so you can build a diversified portfolio. Some HSA providers limit you to a small menu of funds or require you to keep a minimum balance in cash; Vanguard does not.

Timing and what to have ready before you start

Before you contact Vanguard, gather these documents: your current HSA account number, the name and contact information of your current HSA provider, and your Social Security number. If you are opening an HSA at Vanguard for the first time (because your employer or insurer offers Vanguard as an option), you will also need proof that you are enrolled in an HDHP. Your employer or insurer can provide this, usually in the form of a benefits summary or plan document.

The entire process — from deciding to move your HSA to Vanguard to having money invested — typically takes three to four weeks. The transfer itself is one to two weeks, and then you need time to decide what to invest in and place the trades. If you are moving an HSA because you are changing jobs or health plans, start the process as soon as you have your new plan information, because you cannot contribute to the old HSA once you are no longer enrolled in an HDHP.

Frequently Asked Questions

Can I open an HSA directly with Vanguard without going through my employer or health plan?

No. You must have an HSA account number from your health plan or employer first. Vanguard acts as a custodian only — it holds and invests money that is already in an HSA. If your employer or insurer does not offer Vanguard as an option, you can open an HSA elsewhere and then transfer it to Vanguard.

What happens to my HSA if I leave my job?

Your HSA stays yours. It does not belong to your employer. You can keep it where it is, move it to Vanguard, or move it to another provider. You can no longer contribute to it unless your new employer offers an HSA and you enroll in an HDHP, but the money already in it remains available for medical expenses.

Can I invest my HSA in stocks or only in mutual funds?

Vanguard allows you to invest in mutual funds, ETFs, and individual stocks. You can build a portfolio as diversified or as straightforward as you want. The $25 annual custodial fee applies regardless of what you invest in.

What if I need the money before the transfer to Vanguard is complete?

You cannot access the money during a custodian-to-custodian transfer. If you need it urgently, you would have to cancel the transfer and withdraw from your current HSA provider instead. Plan transfers for times when you do not expect to need the money for at least a few weeks.

Does Vanguard charge fees to withdraw money from my HSA?

Vanguard does not charge a withdrawal fee. You pay the annual $25 custodial fee regardless of whether you withdraw money. If you sell investments to fund a withdrawal, you may owe capital gains tax if those investments have gained value, but that is a tax issue, not a Vanguard fee.
