For most investors covered in this treaty series, the first question is how much tax gets withheld. For a mainland Chinese investor, that is the second question. The first is whether you can legally open a US brokerage account at all - and as of 2026, the honest answer is: it depends on documents you may not have.
This guide starts there, because the access problem is more consequential for most readers than the withholding rate itself. Then it works through the treaty mechanics, the W-8BEN process, the critical distinction between mainland China and Hong Kong, the FATCA gap that has existed for over a decade, and the full compliance picture for US citizens living in China. For the general mechanics of how NRA dividend withholding works across all countries, see our US dividend withholding tax guide.
Can You Actually Open a US Brokerage Account? The Real 2026 Picture
This is the section that does not exist in equivalent guides for UK, Australian, or Czech investors, because none of them face it.
The personal foreign exchange quota. China’s State Administration of Foreign Exchange (SAFE) limits individuals to converting RMB into foreign currency up to approximately $50,000 per calendar year for outbound purposes, including funding an overseas brokerage account. This is a long-standing rule, not new for 2026, but enforcement has tightened. From January 1, 2026, Chinese banks apply stricter identity verification and extended record retention (now 10 years) on outbound transfers above RMB 5,000 (roughly $700), following a joint regulation issued by the central bank, banking regulator, and securities regulator in late October 2025. Our multi-currency accounts guide covers how conversion costs and quota tracking typically work for outbound transfers of this kind.
Broker policy has changed materially since 2025. Interactive Brokers tightened its account-opening requirements for mainland China residents in 2025, now requiring proof of overseas residency or employment from the previous three months. Several other brokers serving mainland clients - including Hong Kong-based Futu and Longbridge, and Tiger Brokers - have gone further, suspending or halting new account openings for mainland-only applicants entirely. The driver is twofold: Chinese tax authorities have intensified enforcement of tax collection on individuals’ overseas investment income, and Chinese securities regulators have pressured offshore brokerages to stop providing unlicensed cross-border brokerage access to mainland residents.
What this means practically. A mainland China resident without proof of overseas residency or employment may not be able to open a direct US brokerage account with a major broker in 2026, regardless of how much capital they have or how willing they are to file the correct tax forms. This is a regulatory and compliance reality, not a tax question, and it sits upstream of everything else in this guide.
The realistic pathways that remain:
- QDII funds (Qualified Domestic Institutional Investor): Mainland-regulated funds that invest in overseas markets on behalf of domestic investors. These operate under an institutional FX quota separate from the personal $50,000 limit, and are the primary legal channel for most mainland residents seeking US market exposure without an offshore account.
- Hong Kong-listed ETFs and ADRs: Indirect exposure to US and global equities through instruments listed on the Hong Kong Stock Exchange, typically accessible via Stock Connect or a Hong Kong brokerage relationship.
- An offshore account opened before the relationship existed, or via demonstrated overseas residency or employment: For mainland residents who have lived, worked, or studied abroad, the documentation requirement is often satisfiable. Brokers such as Interactive Brokers and Saxo Bank are the two most commonly used by investors who qualify for direct access. Our broker finder tool can help identify which platforms currently accept applications matching your situation.
None of these pathways carry the same tax treatment as a direct US brokerage account, and the rest of this guide applies most directly to investors using direct access - whether through an existing account, demonstrated overseas ties, or a Hong Kong intermediary holding US-listed securities on their behalf. Where the pathway changes the tax answer, it is noted explicitly below.
The Treaty: What It Actually Covers
The United States-China Income Tax Convention was signed April 30, 1984, and entered into force January 1, 1987. It remains the only comprehensive income tax treaty between the two countries, and - critically, addressed in its own section below - it does not extend to Hong Kong or Macau, which operate independent tax systems.
The verified rates from the treaty text and current guidance:
| Income Type | China Domestic Rate (Non-Resident) | Treaty Rate |
|---|---|---|
| Dividends to a US resident from China-source | 20% | 10% |
| Dividends to a Chinese resident from US-source | 30% | 10% |
| Interest (either direction) | Varies | 10% |
| Royalties (either direction) | Varies | 10% |
| Capital gains - securities | N/A for US NRAs | Taxable in residence country |

Unlike the US-Australia or US-UK treaties, the China treaty does not carve out a separate lower rate for direct corporate ownership above a stated threshold. The 10% dividend rate applies flat, regardless of whether the recipient is a portfolio investor holding a handful of shares or a corporation holding a controlling stake - provided they are the beneficial owner. This is simpler than the Australian or UK structure, but it also means there is no path to a lower rate through larger holdings.
No Totalization Agreement
The United States has Social Security totalization agreements with 26 countries. China is not one of them. For a self-employed US person working in China, or a Chinese national working for a US employer, this means social security contributions can be owed in both countries simultaneously on the same earnings, with no treaty mechanism to avoid the duplication. This is a distinct and often overlooked cost relative to UK, German, or Australian arrangements, all of which have totalization agreements with the US.
Hong Kong Is Not China: A Distinction That Costs People Money
This is the single most common point of confusion for investors in this region, and getting it wrong has direct financial consequences.
The US has no income tax treaty with Hong Kong. Despite Hong Kong being part of the People’s Republic of China under “one country, two systems,” it operates a fully separate tax system, and the US-China treaty explicitly does not extend to it. There is no reduced withholding rate, no treaty-based relief, and no Mutual Agreement Procedure for resolving double taxation between the US and Hong Kong.
What this means for dividends. A Hong Kong tax resident holding US stocks through a Hong Kong brokerage account is not eligible for the 10% treaty rate that a mainland Chinese tax resident can claim. Absent any treaty, the default 30% NRA withholding rate applies to US-source dividends paid to a Hong Kong resident, unless reduced through some other mechanism (none generally apply for individual portfolio investors).
The FATCA structure also differs. Hong Kong signed a Model 2 intergovernmental agreement with the US in November 2014, which is fully operational: Hong Kong financial institutions report US account holder information directly to the IRS. Mainland China’s FATCA situation is materially different and covered in the next section.
The practical takeaway: if you hold US stocks through a Hong Kong brokerage account, you are not covered by the China treaty rate. If your tax residency is mainland China and your account happens to be domiciled in Hong Kong for access reasons, confirm with your broker and a cross-border tax advisor which jurisdiction’s rules actually apply to your withholding, since this depends on your personal tax residency, not merely where the brokerage entity sits.
The FATCA Gap: An Unusually Long “In Substance” Status
China’s institutional FATCA situation is unlike that of any other country covered in this series, and it matters enough to explain precisely.
On June 26, 2014, China and the United States reached an “agreement in substance” for a Model 1 intergovernmental agreement. As of December 31, 2025 - more than eleven years later - that IGA has still not been formally signed, and mainland Chinese financial institutions have not begun systematic FATCA reporting to a Chinese government counterpart under an IGA framework, according to PwC’s China tax summary.
This does not mean a US person holding accounts in China has no FATCA reporting obligation. The personal obligation to file Form 8938 and FinCEN’s FBAR exists under US domestic law regardless of whether China’s institutions report anything. What the unsigned IGA actually affects is the institutional reporting pipeline - the mechanism by which Chinese banks and brokers would automatically flag US-connected accounts to the IRS. That pipeline, for accounts held directly with mainland Chinese institutions, has not been built in the way it has for the UK, Australia, Germany, Japan, or Hong Kong.
For a US person in China, the practical implication is not reduced compliance risk - the IRS can and does pursue US taxpayers through other channels, including direct taxpayer disclosure requirements, and noncompliance penalties for FBAR and Form 8938 are severe regardless of how the IRS eventually learns about an account. The honest reading is that self-reporting obligations remain fully in force; what is missing is the automatic institutional backstop that exists elsewhere.
How to Claim the 10% Treaty Rate: Form W-8BEN
For an investor with a qualifying account - whether a direct US brokerage relationship, an account opened under demonstrated overseas residency, or certain Hong Kong-intermediated structures that pass through to a US-domiciled account - claiming the reduced 10% rate requires Form W-8BEN filed with the broker, not with the IRS directly.
The form establishes non-US person status and treaty country for withholding purposes. If no valid W-8BEN is on file, the default 30% NRA withholding applies. Checking your dividend statement is the simplest verification: a 30% deduction means no treaty rate is being applied; a 10% deduction confirms it is.
W-8BEN expires after three calendar years from the date of signing, consistent with IRS rules across all treaty countries. Brokers generally do not proactively remind account holders before expiry, and reversion to 30% withholding happens automatically once the form lapses.
Given the broker access realities described above, the practical question for many readers is less “how do I file W-8BEN” and more “which broker will let me open an account in the first place.” For those who have cleared that hurdle - through demonstrated overseas residency, an existing account, or a qualifying Hong Kong structure - the W-8BEN process itself is standard and takes a few minutes at account opening. Our guide to opening a US brokerage account as a non-resident covers what to expect at that step.
Capital Gains on US Stocks: No US Tax for Non-Resident Aliens
Under both the treaty’s Article 13 and standard US domestic tax law for non-resident aliens (IRC Section 871), capital gains realized by a non-US person from the sale of US securities are generally not subject to US tax (the narrow exception being US real property interests, which does not apply to portfolio stock or ETF holdings).
This means a mainland Chinese tax resident selling US stocks pays no US capital gains tax on the sale. The gain is taxable, if at all, only in China - and how China taxes it is where the comparison with other countries in this series diverges sharply.
How China Taxes the Same Income: The 2026 Numbers
This is the section that determines what an investor actually keeps, and it differs meaningfully from the UK or Australian pattern.
China taxes dividends, interest, and capital gains from foreign sources at a flat 20% individual income tax rate for tax residents, per the State Taxation Administration’s standard treatment of “income from transfer of property” and investment income categories. This is a flat rate, not part of the progressive 3-45% bracket structure that applies to wages and comprehensive income.
Critically, the preferential treatment available for China-listed shares does not extend to US stocks. Dividends and capital gains from shares traded on the Shanghai, Shenzhen, or Beijing exchanges receive substantial relief - a 50% or 100% reduction on dividend tax depending on holding period, and a general capital gains exemption for individual investors. None of that applies to foreign-source income. A Chinese tax resident’s gains and dividends from US stocks are taxed at the full 20% flat rate, with a foreign tax credit available for tax already paid to the US.
Worked example - dividend income: (our investment calculators tool can run these numbers against your own dividend income)
- Receives $3,000 in US dividends
- US withholding at treaty rate = $300 (10%)
- China domestic flat rate on the same $3,000 = $600 (20%)
- Foreign tax credit for the $300 already paid to the US
- Additional China tax owed: $300
- Total tax paid across both jurisdictions: $600 (20% overall - the treaty prevents double taxation but does not reduce the combined rate below China’s own 20%)
Worked example - capital gains:
- Sells US stock for a $5,000 gain
- US tax: $0 (NRA capital gains exemption applies)
- China domestic flat rate: 20% = $1,000
- No foreign tax credit available, because no US tax was paid to credit against
- Total tax: $1,000, payable entirely to China
The mechanism that benefits UK and Australian investors - where capital gains escape source-country tax and the residence country’s own capital gains regime (with allowances, discounts, or exemptions) applies - works differently for a Chinese tax resident, because China’s flat 20% rate on foreign capital gains carries none of the relief available on domestically listed shares. For a real example of how gains and holding periods compound over years in a US-listed position, see our TQQQ recovery case study.
Non-domiciled foreign nationals working in China receive a partial reprieve: under the “six-year rule,” a non-Chinese-passport holder who has not been continuously resident in China for six years can generally have foreign-source income, including US investment income, exempted from Chinese tax until that threshold is met. This does not apply to Chinese citizens, regardless of where they live or hold accounts.
US Citizens and Green Card Holders in China: The Compliance Picture
Article 1 of the treaty preserves the saving clause: each country retains the right to tax its own citizens as if the treaty did not exist. For US citizens and green card holders in China, this has specific consequences.
Form 1040 remains mandatory every year, reporting worldwide income including Chinese-source salary, investment income, and any QDII fund holdings.
Foreign Tax Credit (Form 1116) generally offsets Chinese tax paid against US tax liability. Given China’s rates - up to 45% on comprehensive income, a flat 20% on most investment income - the FTC typically eliminates most or all additional US federal tax for income already taxed in China, though filing remains required regardless of the final liability.
FBAR (FinCEN Form 114) is required if aggregate foreign account balances, including Chinese bank and brokerage accounts, exceed $10,000 at any point during the year.
Form 8938 (FATCA) applies at the standard thresholds for taxpayers living abroad: $200,000 at year-end or $300,000 at any point for single filers; $400,000/$600,000 for married filing jointly. As established above, the absence of a signed institutional IGA with mainland China does not remove this personal filing requirement.
QDII funds and other Chinese-domiciled pooled investments are PFICs. A US person holding a QDII fund, a Chinese mutual fund, or any other Chinese-domiciled pooled investment vehicle is holding a Passive Foreign Investment Company under US tax law. PFIC taxation defaults to a punitive regime - gains taxed at the highest ordinary rate plus an interest charge calculated back to the year of investment - and Form 8621 must be filed annually for each fund. For a US person who would otherwise use QDII funds as their access route to global markets (a common pattern given the access barriers described earlier), this creates a direct conflict: the same fund structure that solves the access problem for a Chinese national creates a tax problem for a US person. US citizens in China should generally hold US securities directly or through US-domiciled ETFs - including leveraged funds like TQQQ, which carry their own distinct tax profile - where their account access allows it, rather than through QDII or other Chinese-domiciled fund structures. For the broader cross-border picture, see our expat financial planning guide.
How the US-China Treaty Compares to Other Major US Treaties
For a full side-by-side comparison across every US treaty country, our tax map tool visualizes all the rates below. The verified figures for this article’s comparison set:
| Country | US Dividends (Portfolio) | Interest | Capital Gains | Direct Corporate Rate | Totalization Agreement |
|---|---|---|---|---|---|
| China | 10% (flat) | 10% | Residence only | None (flat 10%) | No |
| Australia | 15% | 10% | Residence only | 5% (10%+ ownership) | Yes |
| United Kingdom | 15% | 0% | Residence only | 5% (10%+ ownership) | Yes |
| Czech Republic | 15% | 0% | Residence only | 5% (10%+ ownership) | No |
| Austria | 15% | 0% | Residence only | 5% (10%+ ownership) | Yes |
| Belgium | 15% | 0% | Residence only | 0% (80%+ ownership) | Yes |
| Israel | 25% | 10% | Residence only | 12.5% (10%+ ownership) | No |
| Japan | 10% | 0% | Residence only | 0% (qualifying parent) | Yes |
China’s flat 10% dividend rate is among the lowest of any major US treaty partner, tied with Japan and meaningfully below the UK, Czech Republic, Austria, Belgium, or Australia’s 15%. Where China’s treaty is comparatively weaker is interest income (10%, versus 0% for the UK, Czech Republic, Austria, Belgium, and Japan) and the absence of a totalization agreement, which all of these countries except the Czech Republic have.
The rate comparison, however, is the smaller part of the China story. The access barrier - whether a mainland resident can open a compliant account at all - and the absence of preferential domestic tax treatment for foreign securities are the factors that most affect what a Chinese investor in US markets actually nets, far more than the 5-percentage-point difference in treaty dividend rates relative to other countries.
Common Mistakes That Cost Money or Create Compliance Risk
Assuming a Hong Kong brokerage account gets the China treaty rate. It does not. Hong Kong has no US tax treaty. Confirm tax residency and account domicile separately before assuming any reduced rate applies.
Funding an account through methods that bypass the personal FX quota. Structuring transfers across multiple accounts or counterparties to exceed the $50,000 annual quota is the exact pattern the 2026 enhanced KYC and 10-year record retention rules were designed to detect. This is a regulatory compliance risk independent of any tax question.
Believing the unsigned FATCA IGA removes personal reporting obligations. It does not. FBAR and Form 8938 obligations for US persons exist under US domestic law regardless of China’s institutional FATCA status. If terms like IGA, FBAR, or QDII are unfamiliar, our glossary defines them in plain language.
Assuming Chinese-listed share tax relief extends to US holdings. It does not. The capital gains exemption and dividend reduction available on Shanghai, Shenzhen, and Beijing exchange-listed shares apply only to those shares. US stocks are taxed at the full flat 20% rate with no equivalent relief.
US persons holding QDII funds for convenience. QDII funds solve a Chinese national’s access problem but create a PFIC problem for a US person. The structures that work for one do not work for the other.
Not confirming broker eligibility before assuming direct US market access is available. Given how quickly broker policy has shifted since 2025, confirming current account-opening requirements with the specific platform before relying on direct access is essential.
Practical Checklist
Mainland Chinese resident considering direct US stock access:
- Confirm whether you can demonstrate overseas residency or employment from the past three months, which most major brokers now require for mainland applicants
- If direct access is not available, evaluate QDII funds or Hong Kong-listed ETF/ADR exposure as the realistic alternative
- Confirm your remittances stay within the $50,000 annual personal FX quota and are properly documented
- File W-8BEN once an account is open; check dividend statements for the 10% (not 30%) deduction rate
- Renew W-8BEN before the three-year expiry
Hong Kong resident holding US stocks:
- Confirm you are not assuming the China treaty rate applies - it does not for Hong Kong tax residents
- Check whether 30% default withholding is being applied and factor this into return expectations
Chinese tax resident with realized US investment income:
- Report US dividends and capital gains as foreign-source income on your Chinese tax filing
- Apply the foreign tax credit for US withholding already paid on dividends
- Remember capital gains receive no equivalent foreign tax credit, since no US tax was paid on them
- Do not assume the China-listed share exemptions apply to foreign holdings
US citizen or green card holder living in China:
- File Form 1040 annually, including Chinese-source income and any QDII holdings
- Claim Foreign Tax Credit (Form 1116) for Chinese tax paid
- File FBAR if aggregate Chinese account balances exceed $10,000 at any point
- File Form 8938 if total foreign financial assets exceed the applicable threshold
- Avoid QDII funds and other Chinese-domiciled pooled vehicles due to PFIC treatment; prefer direct US securities or US-domiciled ETFs
- Confirm social security contribution obligations given the absence of a US-China totalization agreement
Key Takeaways
The US-China treaty delivers one of the most favorable dividend withholding rates available to any country’s investors - a flat 10%, tied with Japan and better than the UK, Czech Republic, or Australia’s 15%. For an investor who can actually access US markets directly, that rate advantage is real.
The access question is the larger story for 2026. Mainland Chinese residents face a personal foreign exchange quota, intensified compliance scrutiny on outbound transfers, and brokers that have materially tightened account-opening requirements since 2025. For many readers, the realistic path to US market exposure runs through QDII funds or Hong Kong-listed instruments rather than a direct US brokerage account - and each of those paths carries its own tax treatment, distinct from what this guide’s treaty rates assume.
Hong Kong is not covered by the China treaty, a distinction that catches investors who assume “China” and “Hong Kong” share the same tax framework. The unsigned FATCA IGA, now over a decade in “agreement in substance” limbo, changes the institutional reporting pipeline without changing any individual’s personal compliance obligations.
For Chinese tax residents, the absence of preferential treatment for foreign securities means US-source investment income is taxed at China’s full flat 20% rate, with the foreign tax credit preventing double taxation but not reducing the combined burden below that rate. For US citizens in China, PFIC exposure on QDII funds and the absence of a totalization agreement are the two compliance issues most likely to be overlooked - and most costly when they are.
