How to Open a Vanguard Brokerage Account — A Beginner’s Step-by-Step Guide with 1099 Tax Basics (Updated for 2026)
“I want to start investing in the U.S., but how do I actually open a Vanguard brokerage account?”
This guide walks you through the Vanguard Brokerage Account setup process in plain English — from account creation to your first trade — and explains how dividends and stock sales show up on your tax return (Forms 1099-DIV and 1099-B).
The focus is practical, beginner-friendly, and written from a U.S. tax professional’s perspective.
Opening a Vanguard brokerage account typically follows this flow:
create a login → choose account type → verify identity → link a bank → fund the account → place your first trade.
If you open a taxable brokerage account, dividends and sales are reported to the IRS via Form 1099-DIV and Form 1099-B.

1️⃣ Brokerage vs. IRA: which account should you open?
At Vanguard, the term “investment account” can mean two very different things:
a taxable brokerage account or a retirement account (Traditional IRA or Roth IRA).
The decision comes down to timing and tax treatment.
• Brokerage account: dividends and sales are taxable in the year they occur
• IRA: investments grow under special tax rules, with taxes triggered mainly at withdrawal
2️⃣ What you need before starting
- Legal name, date of birth, and Social Security number
- U.S. address, email address, and phone number
- Bank account details for ACH transfers
Account setup is fast, but bank verification and fund availability may take a few business days.
3️⃣ How to open a Vanguard brokerage account
- Create a Vanguard online profile (web or mobile app)
- Select “Brokerage Account” during setup
- Complete identity verification and disclosures
- Link a bank account and request your first transfer
4️⃣ Funding your account & understanding the settlement fund
New investors are often surprised that money sent to Vanguard does not immediately turn into stock purchases.
Incoming funds first land in a settlement fund.
Vanguard typically uses Vanguard Federal Money Market Fund (VMFXX) as its default cash holding.
If you can’t place a trade yet, check whether your funds have fully settled.
5️⃣ Tax basics: 1099-DIV and 1099-B explained
- Form 1099-DIV: reports dividends and capital gain distributions
- Form 1099-B: reports stock and ETF sales
• 1099-DIV is generally issued when total dividends reach $10 or more
• Very small dividend amounts may not trigger a form, but they can still be taxable
Most securities purchased after 2011 are classified as covered securities.
This means Vanguard reports both sale proceeds and cost basis directly to the IRS.
Skipping or guessing numbers on your tax return can easily trigger a mismatch.
Vanguard usually releases a consolidated 1099 package between late January and mid-February.
Filing too early can result in amended returns.
6️⃣ Common beginner mistakes to avoid
- Opening the wrong account type
- Trying to trade before funds settle
- Assuming dividends are tax-free
- Reinvesting sale proceeds without considering taxes
- Ignoring 1099 forms during tax season
-
Selling at a loss and repurchasing the same security within 30 days
→ wash sale rules disallow the loss
❓ Frequently asked questions
Do I owe taxes if I never sell my stocks?
Possibly. In a taxable brokerage account, dividends alone can create taxable income.
