Bottom line
Yes — Vanguard accepts ITIN for brokerage and IRA accounts, but the online application may reject ITIN at the SSN field. Call Vanguard at 800-662-7447 or request a paper application to complete the process manually. Vanguard ETFs like VTI and VXUS are also available commission-free at other brokerages such as Fidelity, which has a smoother ITIN application process.
Does Vanguard Accept an ITIN?
Yes — Vanguard accepts ITIN for individual taxable brokerage accounts, Roth IRAs, and traditional IRAs. The catch is that Vanguard's online application was originally designed for SSN holders and the SSN field may reject an ITIN. The fix is straightforward: call Vanguard at 800-662-7447 or request a paper application, and phone representatives can process ITIN accounts manually.
Vanguard's investor information page at investor.vanguard.com covers the tax forms ITIN holders need to complete when opening an account.
Why Does Vanguard's Online Application Reject My ITIN?
Vanguard's online form validates the SSN field format and may not recognize an ITIN, which starts with the digit 9 and has a middle section of 70–88, 90–92, or 94–99. The form isn't designed to reject ITIN holders intentionally — it's a legacy technical limitation. Calling 800-662-7447 or submitting a paper application bypasses this entirely, routing you to representatives who open ITIN accounts regularly.
What to do if the online form rejects you
Call Vanguard at 800-662-7447 (weekdays, 8 a.m. – 8 p.m. ET). Tell the representative you have an ITIN and want to open an account. You can also request a paper application by mail. Both paths work — the phone route is faster.
Platform transition — confirm when you call
Vanguard is migrating from its legacy mutual fund platform to a full brokerage platform. Some account types may be in transition. When you call, confirm which account types are currently available for ITIN holders and whether paper applications are still required for any of them.
Which Vanguard Account Types Accept ITIN?
ITIN holders can open 3 main account types at Vanguard: individual taxable brokerage, Roth IRA, and traditional IRA. Joint accounts typically require both account holders to have valid tax IDs; if only one person has an ITIN, confirm joint account eligibility when you call. Business accounts and custodial (UGMA/UTMA) accounts may have additional requirements.
| Account Type | ITIN Accepted | Notes |
|---|---|---|
| Individual taxable brokerage | Yes | No minimum; ETFs available from $1 |
| Roth IRA | Yes | Must have earned income; 2026 limit $7,500/$8,500 |
| Traditional IRA | Yes | Deductibility depends on income and employer plan |
| Joint brokerage | Confirm | Verify when calling if only one holder has ITIN |
Can ITIN Holders Buy Vanguard ETFs Like VTI and VXUS?
Yes — ITIN holders can buy Vanguard ETFs like VTI (Total Stock Market), VXUS (Total International Stock), VOO (S&P 500), and BND (Total Bond Market) at Vanguard or at any other brokerage that accepts ITIN. ETFs trade like stocks, so there is no fund minimum — you can buy a single share or a fractional share at brokerages that offer fractional trading. Fidelity, which has a smoother ITIN application process, offers all Vanguard ETFs commission-free.
Fidelity as an alternative for Vanguard ETFs
If Vanguard's application process is frustrating, open an account at Fidelity instead. Fidelity's online application accepts ITIN directly, and you can buy VTI, VXUS, VOO, and BND there commission-free — the same Vanguard ETFs, just through a different broker with a smoother signup flow.
What Are Vanguard's Minimum Investment Requirements for ITIN Holders?
Vanguard ETFs have no minimum investment — you buy whole shares (or fractional shares where supported). Vanguard mutual funds, however, have minimums: most Admiral Shares mutual funds require $3,000 to start, and some Investor Shares have a $1,000 minimum. The same minimums apply whether you have an SSN or an ITIN. If you're starting with less than $3,000, buy Vanguard ETFs instead of mutual funds.
| Investment Type | Minimum | Example |
|---|---|---|
| Vanguard ETFs | $0 (1 share) | VTI, VXUS, VOO, BND |
| Vanguard Investor Shares (mutual funds) | $1,000 | Select fund series |
| Vanguard Admiral Shares (mutual funds) | $3,000 | VTSAX, VTIAX, VBTLX |
Why ETFs are better for ITIN holders starting out
If you have less than $3,000, buy VTI (the ETF equivalent of VTSAX) and VXUS instead of waiting until you hit the mutual fund minimum. The expense ratios are nearly identical (VTI is 0.03%), and ETFs trade like stocks so you can start with a single share. This is true whether you open at Vanguard or Fidelity.
Do I Fill Out a W-9 or W-8BEN at Vanguard With an ITIN?
It depends on your U.S. tax residency status. ITIN holders who meet the IRS substantial presence test or hold a green card are considered U.S. tax residents and complete a W-9 using their ITIN. ITIN holders who are non-residents for tax purposes complete a W-8BEN, which also accepts an ITIN in place of an SSN. Vanguard will ask about your residency status when you open your account and will tell you which form applies.
| Tax Status | Form to Submit | Key Detail |
|---|---|---|
| U.S. tax resident (substantial presence or green card) | W-9 | Enter ITIN where SSN is requested |
| Non-resident alien for tax purposes | W-8BEN | Enter ITIN in line 5 (U.S. TIN) |
What Are the Best Alternatives If Vanguard Won't Process My ITIN?
If Vanguard's process is too slow or frustrating, 3 brokerages accept ITIN with an online application that works: Fidelity (no minimums, fractional shares, zero-expense-ratio index funds), Charles Schwab (no minimums, commission-free ETFs), and Interactive Brokers (good for non-resident aliens with investment accounts abroad). All three carry Vanguard ETFs like VTI and VXUS commission-free.
