When trading U.S. stocks, you often encounter tax challenges such as high dividend tax rates, capital gains tax misconceptions, and low estate tax thresholds. Many investors face issues due to improper filing of the W-8BEN form, resulting in the inability to enjoy the tax benefits under the U.S.-China tax treaty and even facing scrutiny from the U.S. Internal Revenue Service (IRS). The table below outlines two main tax types and their rates in U.S. stock trading:
| Tax Type | Tax Rate | Description |
|---|---|---|
| Capital Gains Tax | 20% | Non-residents are generally exempt, but must meet identity and residency duration requirements. |
| Dividend Tax | 20% | The U.S. withholds 10%, and China requires an additional 10%, resulting in a high overall tax burden. |
You need to dynamically manage your tax status and plan your cash flow to better achieve compliance and tax-saving goals.

When you receive dividends from listed companies in U.S. stock trading, you need to focus on dividend tax. The U.S. imposes a 10% withholding tax on non-U.S. tax residents (including Chinese investors). U.S. brokers automatically deduct this tax when distributing dividends. Under the U.S.-China tax treaty, you also need to pay an additional 10% personal income tax in China. As a result, the total tax burden on dividends is approximately 20%.
| Applicable To | Dividends received during the holding period |
|---|---|
| Tax Rate Composition | U.S. withholds 10%, China requires an additional 10%, totaling about 20% |
Tip: Even if you incur an overall investment loss in a year, you still need to pay dividend tax if you receive dividends.
You should note that brokers automatically withhold the U.S. portion of the tax. You also need to actively declare and pay the remaining tax in China. The choice of broker registration location does not affect your tax obligations; the key lies in your tax residency status.
The profit you earn from buying and selling stocks in U.S. stock trading is considered capital gains. The U.S. generally does not impose capital gains tax on non-U.S. tax residents, provided you do not have a permanent establishment in the U.S. or engage in local business activities. This means most Chinese investors are exempt from U.S. capital gains tax.
However, as a Chinese tax resident, you must pay tax on your global income. Capital gains from U.S. stocks are classified as “property transfer income” and are subject to a 20% personal income tax rate. You can deduct eligible overseas investment losses before tax. If you have already paid related taxes in the U.S. or other regions, you can apply for a tax credit to avoid double taxation.
You need to declare capital gains from U.S. stock trading on your own and plan your investments reasonably to avoid underreporting and legal risks.
The stock assets you accumulate through U.S. stock trading may be subject to U.S. estate tax in the future. According to the 2025 U.S. federal estate tax policy, the exemption amount is $13,990,000 (equivalent to the current RMB exchange rate). Only the portion of the estate exceeding this amount is subject to estate tax. While most investors will not reach this threshold, high-net-worth investors need to plan ahead.
Note: The U.S. estate tax threshold is high, but the tax burden is heavy once exceeded. You should monitor changes in your asset size and consult professionals to arrange cross-border wealth inheritance.
During U.S. stock trading, you must pay attention to your tax status, declaration process, and compliance risks. China has strengthened oversight of individual overseas income, clearly requiring income from U.S. stock trading to be subject to personal income tax. You need to actively declare to avoid tax risks due to increased information transparency.
When opening a U.S. stock trading account, you typically need to fill out the W-8BEN form. This form, issued by the U.S. IRS, is used by non-U.S. tax residents to declare their status and apply for tax treaty benefits. Properly filling out the W-8BEN form allows you to enjoy the dividend tax rate benefit under the U.S.-China tax treaty, reducing the U.S. dividend withholding tax rate from 30% to 10%. If you fail to submit or fill out the form incorrectly, brokers will default to withholding 30% tax, increasing your tax burden.
When filling out the W-8BEN form, you need to pay attention to the following key points:
Tip: You can only enjoy the automatic 10% dividend tax withholding by U.S. brokers if you correctly submit the W-8BEN form. Otherwise, your tax burden will significantly increase.
In U.S. stock trading, you generally do not need to file a capital gains tax return with the U.S. IRS as long as you do not have a permanent establishment in the U.S. or engage in local business activities. The U.S. exempts non-U.S. tax residents from capital gains tax. However, for dividend income, U.S. brokers will automatically withhold 10% tax based on your submitted W-8BEN form and remit it to the IRS. You receive the net amount after tax withholding and do not need to file or pay additional taxes in the U.S.
If you wish to reclaim over-withheld dividend tax, you can follow this process:
When opening an account, you need to prepare a scanned copy of your Chinese passport or ID, ITIN approval notice, W-8BEN form, Chinese address and phone number, and Chinese bank account information. Note that the ITIN is valid for three years, and it’s recommended to file a zero-income return every three years to keep the ITIN active.
Note: You must comply with regulatory requirements and avoid using fake identities or proxy account-opening services, which could lead to account freezes or reporting to the IRS.
During the U.S. stock trading declaration process, you may encounter the following misconceptions:
Recommendation: You should regularly monitor changes in tax policies, actively comply with declarations, and avoid tax risks due to increased information transparency. Consult professional tax advisors for complex situations.

As a Chinese tax resident, you must declare your global income, including dividends and capital gains from U.S. stock trading. According to the People’s Republic of China Personal Income Tax Law, you should classify profits from U.S. stock trading as “property transfer income,” subject to a 20% tax rate. You need to complete the declaration between March 1 and June 30 of the following year after earning the income.
You can follow this declaration process:
Tip: Failure to declare on time may result in the tax authorities requiring additional tax payments and late fees, with some cases involving penalties of up to hundreds of thousands of U.S. dollars (USD). Please take it seriously.
The Common Reporting Standard (CRS) has become a key tool for Chinese tax authorities to monitor overseas accounts and investment income. Accounts you open with Hong Kong banks or other overseas financial institutions will have their information automatically exchanged with Chinese tax authorities via CRS. The tax authorities use big data and international information-sharing technology to track your overseas investments and income.
To declare U.S. stock trading income compliantly and reduce tax risks, you can follow these recommendations:
Recommendation: As global tax regulatory technology advances, you should continuously optimize your tax arrangements to ensure every U.S. stock transaction is declared compliantly and transparently.
When investing in U.S. stocks, your biggest concern is likely the same income being taxed by both China and the U.S. In fact, China and the U.S. signed the Agreement on the Avoidance of Double Taxation in 1984, effective in 1986. This agreement allocates taxing rights and reduces withholding tax rates on dividends and interest, helping you reduce the tax burden of cross-border investments. You can use the treaty’s credit mechanism to offset taxes paid in the U.S. against your Chinese tax obligations. This way, you only need to pay the difference to avoid double taxation. The treaty also includes dispute resolution and information exchange provisions to protect your legal rights.
Tip: When declaring, keep tax payment proofs from U.S. brokers, Hong Kong banks, and other institutions to facilitate tax credit applications.
If you receive equity incentives from a U.S.-listed company, tax treatment becomes more complex. When exercising options, you must pay personal income tax at a rate of 3%-45% as wage and salary income, with the tax base being the market price minus the exercise price. Dividends received during the holding period are subject to a 20% dividend tax, and profits from selling the shares are subject to a 20% property transfer income tax. The table below summarizes the main tax stages:
| Tax Stage | Tax Type | Tax Rate | Description |
|---|---|---|---|
| At Exercise | Wage and Salary Income | 3%-45% | Market price minus exercise price multiplied by the number of shares |
| Holding Period Dividends | Dividend Tax | 20% | Dividend income must be declared separately |
| Sale and Realization | Property Transfer Income Tax | 20% | Sale price minus market price at exercise multiplied by the number of shares |
You should pay attention to the applicability of tax incentives and plan the timing of exercise and realization to avoid excessive tax burdens.
You can reduce the overall tax burden of U.S. stock trading through various methods:
You should align your investment structure and cash flow with tax treaties and credit policies to ensure every U.S. stock transaction is declared compliantly and transparently, reducing future tax risks.
In U.S. stock trading, compliant declarations and risk prevention are critical. Please refer to the following checklist:
Recommendation: Regularly review your investment accounts and declaration records, and consult professionals promptly for any doubts to ensure every cross-border investment is compliant and secure.
You need to declare. Chinese tax law requires you to pay tax on your global income, including dividends and capital gains from U.S. stock trading. You should complete your annual declaration within the specified period.
If you do not fill out the W-8BEN form, U.S. brokers will withhold 30% dividend tax. You will not enjoy the 10% preferential tax rate under the U.S.-China tax treaty, significantly increasing your tax burden.
You can apply for a tax credit in China using tax documents from U.S. brokers or Hong Kong banks. You only need to pay the tax difference to avoid double taxation.
Yes, it does. Hong Kong banks and other financial institutions will automatically exchange your account information with Chinese tax authorities via CRS. You need to truthfully declare to avoid tax risks.
You can only use U.S. stock investment losses to offset profits from U.S. stock trading in the same tax year. You cannot offset losses against wages, interest, or other income types, nor carry losses forward to future years.
