Excited about Apple or Tesla stocks but not sure how to get started?

Investing in US stocks gives you the opportunity to share in the growth dividends of the world’s top companies. The US market offers attractive returns, for example, the S&P 500 index has achieved an average annual return of 11.3% over the past decade. For those of us in mainland China, the core question is how to open an account safely and conveniently. This guide provides a nanny-level tutorial, step by step guiding you to choose a reliable US stock broker and complete the application.

Key Points

• Opening an account directly with a US broker is the best way to invest in US stocks, ensuring your fund security and lower trading fees.
• When choosing a US stock broker, prioritize whether it is strictly regulated by the US SEC and FINRA, and whether it has SIPC fund protection.
• If you are a US stock investment beginner, Firstrade is a great choice—it is easy to operate, has comprehensive Chinese language support, and offers commission-free trading.
• If you are an experienced investor, Interactive Brokers (IBKR) provides powerful trading tools and lower margin rates.
• Before opening an account, prepare your passport or ID card, proof of address, and sign the W-8BEN form to exempt you from US capital gains tax.

Comparison of US Stock Account Opening Methods

Understanding different account opening methods is your first step. For investors in mainland China, there are mainly two ways to enter the US stock market. You need to choose the most suitable option based on your situation.

Method One: Directly Open with Overseas Brokers

This method means you directly open an account with a licensed online US stock broker in the US.

• Your Identity: You directly become the broker’s client, with assets protected by the Securities Investor Protection Corporation (SIPC).
• Asset Ownership: Stocks and funds are directly held in your personal name.
• Operation Process: The entire application process is completely online and very convenient.

Core Advantages: This method offers the highest autonomy, strongest fund security, and usually lower trading costs, making it the most mainstream and highly recommended choice currently.

Method Two: Mainland Broker Complex Entrustment

Complex entrustment means you trade US stocks through a mainland Chinese securities company (or its Hong Kong subsidiary).

• Operation Principle: Your orders are passed by the mainland broker to a cooperating US broker for execution.
• Asset Ownership: Assets may nominally be held under the broker’s name rather than directly in your personal name.
• Higher Fees: Due to an additional intermediary layer, trading commissions and platform fees are usually higher.

This method’s convenience lies in possibly simplifying the funding process but sacrifices cost and some security.

Security, Fees, and Convenience Comparison

To help you make a more intuitive choice, we compare the core differences between the two methods in a table.

Overall, directly opening an account with an overseas broker is the more advantageous choice.

After deciding on direct account opening, the next step is to select the one that best suits you from numerous brokers. This decision is crucial because it directly relates to your fund security and future trading experience.

Core Selection Criteria: Regulation and Security

When choosing a US stock broker, your first consideration should not be trading fees but regulation and security. A reliable broker must be strictly regulated in the US financial system.

The main regulatory bodies are two:

• SEC (U.S. Securities and Exchange Commission): Responsible for registering all brokers selling securities to the public and overseeing its subordinate FINRA.
• FINRA (Financial Industry Regulatory Authority): Directly supervises US brokers. It sets strict conduct and financial requirements, ensures compliant operations, and conducts comprehensive reviews of brokers to protect investors’ interests.

Additionally, your funds should be protected by SIPC (Secs Investor Protection Corporation). SIPC provides up to $500,000 insurance per client account, including up to $250,000 for cash.

Regulation is not just talk. Historically, regulators have imposed heavy penalties on violations by multiple well-known brokers. For example, Citadel Securities LLC was fined $7,000,000 for mis-marking millions of sell orders; Goldman Sachs was also fined $6,000,000 for failing to provide complete trading information. Choosing a strictly regulated broker adds a security lock to your funds.

Beginner Friendliness and Learning Resources Evaluation

For a newcomer just entering the US stock market, whether the broker is “friendly” directly affects your initial experience.

• Firstrade excels in this area. It not only provides simple tools but also has a large number of Chinese educational articles and videos specifically for beginners, helping you learn investment knowledge from scratch.
• Interactive Brokers (IBKR) also provides abundant learning materials, such as “Traders’ Academy”, but its content depth and professionalism are more suitable for those with some foundation; beginners may feel overwhelmed.

You have chosen your preferred broker; now enter the most critical practical phase. Don’t worry—the entire process is highly online and simplified. You only need to follow the steps below, prepare materials, and easily complete account opening.

Materials Preparation Before Account Opening

Before starting the online application, you need to prepare some key documents in advance. This will greatly speed up your application. The required documents are mainly divided into two categories: identity proof and address proof.

Important Tip: All documents must be “currently valid”, meaning not expired. Brokers require clear and readable files, so ensure your photos or scans are not blurry, reflective, or missing corners.

To make it clear at a glance, we have compiled a list of acceptable documents:

A Convenient Option: If you apply using a Chinese Resident ID Card and the address on the ID is your current residence address, you usually do not need to provide additional address proof documents. This simplifies the process for many users.

Online Application: Complete in 15 Minutes

Now, you can visit your chosen broker’s official website, click the “Open Account” button, and officially start the online application. The entire process is designed to be very user-friendly, usually taking only about 15 minutes to fill out.

Many platforms have very efficient reviews. For example, with institutions like J.P. Morgan, after submitting your application materials, review usually completes within 1 business day. You will receive an account activation notification via email.

Fill in Personal and Financial Information

In this section, you need to truthfully fill in some personal information, including your employment status, annual income, and financial situation. This is a regulatory requirement to ensure the financial products provided to you match your risk tolerance.

You will encounter two key concepts: Total Net Worth and Liquid Net Worth. Understanding their differences is important.

Additionally, you need to select your investment objectives (such as capital appreciation, speculation) and risk tolerance.

• How to Choose? Please fill based on your actual situation. The Financial Industry Regulatory Authority (FINRA) defines “risk tolerance” as your “ability and willingness to lose some or all of the original investment in exchange for greater potential returns”.
• What if objectives are inconsistent? If you have multiple investment goals, such as one account for long-term stable investment and another for short-term trading, you can truthfully explain. The broker needs to understand and record your true intentions.

Identity and Address Verification

After filling in the information, you reach the step of uploading proof documents. You need to photograph or scan the previously prepared identity and address proof documents and upload them.

Please note the file format and size requirements to ensure successful upload.

When uploading, ensure the image content is complete and clear to avoid review delays due to file quality issues.

Sign the W-8BEN Tax Form

As a non-US resident, you need to sign a form called W-8BEN.

• What is its purpose? This form is used to declare to the US Internal Revenue Service (IRS) your “non-US tax resident” status.
• What benefits does it bring you? After signing, you can enjoy tax benefits; the most direct one is exemption from US capital gains tax. That means the US government will not tax the profits you make from buying and selling stocks.

This step is fully electronic; you only need to check and confirm according to prompts in the application process, very convenient.

Account Review: Wait 1-2 Business Days

After submitting all information and documents, you enter the final waiting phase. The US stock broker’s review team will check your application materials.

Usually, the review completes within 1-2 business days. Once the account is approved, you will receive a confirmation email containing your account information and next steps for funding.

Why might review be delayed? Delays are usually not major issues; the most common reasons are unclear submitted documents, incorrect information filling, or the broker needing additional supplementary materials from you. As long as you provide as required, the issue will be resolved quickly.

You have now mastered the core three steps of account opening: First, clearly choose the direct overseas broker method; then, based on your trading frequency and fund amount, select the platform that best suits you; finally, follow this guide’s steps to complete the online application.

Starting US stock investment is an important step toward achieving global asset allocation. Account opening is the starting point of this journey and the most critical step.

Do not let the account opening process hinder your path to global investing. Now, take your first step and start your US stock investment journey!

FAQ

How to fund a US stock account?

You need to wire transfer through your overseas bank account. For example, you can initiate a USD wire transfer from your Hong Kong bank account to the broker’s designated receiving account. The broker App will provide detailed remittance guidance and information.

Do I need to pay taxes on US stock investments?

Profits from buying and selling stocks (capital gains) are tax-exempt.

But dividends (stock dividends) you receive need to be taxed, usually at a rate of 10%. The broker will automatically withhold this tax for you; you do not need to declare it yourself.

If the broker goes bankrupt, is my money safe?

Yes, your account is protected by the Securities Investor Protection Corporation SIPC. Each account can receive up to $500,000 in compensation protection, including up to $250,000 in cash. This provides a strong safety net for your assets.

Is there a minimum amount requirement for investing in US stocks?

Most brokers have no minimum deposit requirement. In theory, you only need enough funds to buy one share of stock to start. Now many brokers also support fractional shares, allowing you to invest in high-priced stocks with very little money, such as $5.
