This checklist covers the U.S. federal tax filing topics that come up most often for taxpayers with financial ties to China: deadlines, foreign account reporting (FBAR and FATCA), Passive Foreign Investment Company (PFIC) issues, streamlined filing options for taxpayers who missed prior-year filings, and a few items specific to Bay Area tech employees and small-business owners. It is descriptive, not a substitute for advice on your specific facts. Every item below should be confirmed with a qualified tax advisor before you act on it.
本指南涵盖与中国有资产联系的纳税人最常遇到的美国联邦报税主题:申报截止日期、海外账户申报(FBAR与FATCA)、被动外国投资公司(PFIC)问题、错过以往年度申报的纳税人可用的简化合规程序,以及湾区科技员工和小企业主特别需要注意的事项。本指南仅为一般性说明,不能替代针对您具体情况的专业建议。在采取任何行动前,请务必与合格的税务顾问确认每一项内容。
1. Filing Deadlines / 申报截止日期
Form 1040 截止日期
联邦个人所得税申报表(Form 1040)通常截止日期为4月15日。可通过提交Form 4868申请自动延期至10月15日,但延期只延长申报表的提交时间,不延长缴税时间,欠税部分仍须在4月15日前缴清,否则可能产生罚款和利息。
Form 1040 deadline
Form 1040 is generally due April 15. Filing Form 4868 grants an automatic extension to October 15, but that extension applies to the paperwork only, not to payment. Any tax owed is still due April 15 to avoid penalties and interest.
2. FBAR (FinCEN Form 114)
一万美元合计门槛
根据31 CFR 1010.350,如果您是美国税务居民,并对海外金融账户拥有所有权或签字权,当这些账户总额在一年中的任何时点超过一万美元时,您必须提交FinCEN Form 114(FBAR)。这个门槛是所有海外账户的合计金额,不是单个账户的余额,且以全年最高点计算,不是年末余额。FBAR通过FinCEN的BSA电子申报系统单独提交,不随Form 1040一起申报,截止日期为4月15日,自动延期至10月15日。
中国银行账户(工商银行、中国银行、建设银行等存款账户)、A股证券账户,以及具备账户功能的支付宝/微信支付余额,均可能计入申报范围;需具体分析(facts-and-circumstances)。
The $10,000 aggregate threshold
Under 31 CFR 1010.350, a U.S. person with a financial interest in, or signature authority over, foreign financial accounts must file FinCEN Form 114 (FBAR) if the combined value of those accounts exceeded $10,000 at any point during the year. The threshold is aggregate across every account, not per account, and tested at the year's highest point, not year-end. FBAR is filed separately from Form 1040 through FinCEN's BSA E-Filing System, due April 15 with an automatic extension to October 15.
Chinese bank deposit accounts (ICBC, Bank of China, China Construction Bank, and similar), A-share brokerage accounts, and WeChat Pay/Alipay balances that function as a stored-value account may all be reportable, depending on the specific facts.
3. FATCA: Form 8938 (IRC §6038D)
随Form 1040一并申报,门槛更高
依据《美国国内税收法典》第6038D条(FATCA),特定海外金融资产需在Form 8938中申报,该表格随Form 1040一起提交。截至2025纳税年度,门槛为:单身且居住在美国境内的申报人,年末资产超过5万美元或全年任何时点超过7.5万美元;已婚联合申报,门槛翻倍为年末10万美元或全年任何时点15万美元。Form 8938涵盖的资产范围比FBAR更广,包括直接持有的海外股票和海外合伙权益。
Filed with Form 1040, higher thresholds
Under IRC Section 6038D (FATCA), specified foreign financial assets are reported on Form 8938, filed with Form 1040. As of tax year 2025, thresholds for a single filer living in the U.S. are $50,000 at year-end or $75,000 at any point during the year; married filing jointly doubles those to $100,000 and $150,000. Form 8938 reaches a broader category of assets than FBAR, including foreign stock held directly and interests in foreign partnerships.
4. PFIC Issues (IRC §1291–§1298)
中国公募基金、ETF与投连险
许多中国公募基金、ETF以及投资连结型保险产品可能符合《国内税收法典》第1297条对"被动外国投资公司"(PFIC)的定义。如未依据第1295条及时做出合格选择性基金(QEF)选举,相关收益及部分分红将适用第1291条规定的"超额分配"制度征税,通常远比普通资本利得税负更重,且需缴纳递延利息。每一项持仓都应单独评估。
Chinese mutual funds, ETFs, and insurance wrappers
Many Chinese mutual funds, ETFs, and investment-linked insurance wrappers meet the definition of a Passive Foreign Investment Company under IRC Section 1297. Without a timely Qualified Electing Fund election under Section 1295, gains and certain distributions are taxed under the excess distribution regime of Section 1291, generally far more punitive than ordinary capital gains treatment, plus a deferred-tax interest charge. Each holding should be evaluated individually.
5. Streamlined Filing Compliance Procedures
SDOP(境内程序)与SFOP(境外程序)
如果您过去因非故意疏忽而未申报海外账户,IRS的"简化申报合规程序"(Streamlined Filing Compliance Procedures)允许以较低罚款补报。境内简化程序(SDOP)适用于美国居民,需补报近三年税表及近六年FBAR,并对最高账户余额缴纳5%的境外资产罚款。境外简化程序(SFOP)适用于符合"非居民测试"条件的纳税人,无需缴纳境外资产罚款(0%)。是否符合"非故意"标准,须由合格税务顾问依据具体事实判断。
SDOP vs. SFOP
If past non-compliance was non-willful, the IRS Streamlined Filing Compliance Procedures allow a reduced-penalty path back into compliance. The Streamlined Domestic Offshore Procedures (SDOP) apply to U.S. residents: amended returns for three years, delinquent or amended FBARs for six years, and a 5% miscellaneous offshore penalty on the highest aggregate account balance. The Streamlined Foreign Offshore Procedures (SFOP) apply to taxpayers who meet a non-residency test and carry no offshore penalty (0%). Whether your facts support the non-willful standard is a determination a qualified tax advisor should make with you.
6. Common China-Based Assets: How They're Typically Treated
常见中国资产的一般处理方式
| Asset / 资产类型 | Typical Treatment / 一般处理方式 |
|---|---|
| 存款账户 (ICBC, BOC, CCB) / Deposit accounts | Generally reportable on FBAR above the $10,000 aggregate threshold; Form 8938 if the higher threshold is also met. 一般在超过FBAR一万美元合计门槛时需申报;若同时满足Form 8938更高门槛,亦需申报。 |
| A股经纪账户 / A-share brokerage accounts | Generally reportable on both forms where applicable; underlying holdings should be screened for PFIC status. 通常两表均可能适用;应对底层持仓进行PFIC筛查。 |
| 香港账户 / Hong Kong bank/brokerage accounts | Generally treated on the same basis as mainland accounts. 一般与大陆账户适用相同规则。 |
| 支付宝 / 微信支付: WeChat Pay / Alipay balances | Reportable if the balance functions as a stored-value account rather than a pure payment pass-through; facts-and-circumstances review. 若余额具备储值账户性质而非单纯支付通道,通常需申报;须具体分析。 |
| 社保 (China social insurance / employer-employee system) | UNVERIFIED · 待核实 Generally understood as a government program rather than an individually held account and typically not itself FBAR/8938-reportable, but this should be confirmed for your specific facts with a qualified tax advisor before relying on it. 一般被视为政府项目而非个人持有账户,通常本身无需申报,但请务必就您的具体情况向合格税务顾问核实后再行判断。 |
| 海外房产 / Real estate held directly in China | Directly held real estate is generally not itself an FBAR "account," but associated cash, escrow, or entity interests used to hold it may independently be reportable. 直接持有的房产本身通常不构成FBAR意义上的"账户",但用于持有房产的相关现金、托管账户或实体权益可能单独需要申报。 |
7. Bay Area Tech Employees / 湾区科技员工
RSU/ISO/NSO与预估税
- 限制性股票单位(RSU)归属时通常按普通收入计税;需确认雇主预扣税是否足额。
- 激励型股票期权(ISO)可能触发替代性最低税(AMT);非法定股票期权(NSO)行权时通常按普通收入计税。
- 季度预估税:依据第6654(d)(1)(B)条,若上一年调整后总收入超过15万美元(单身或已婚联合申报均适用此门槛,已婚分别申报为7.5万美元),安全港比例为上一年税额的110%(而非通常的100%)。
RSU/ISO/NSO and estimated tax
- RSUs are generally taxed as ordinary income at vesting; confirm whether employer withholding is sufficient.
- ISOs can trigger the Alternative Minimum Tax (AMT); NSOs are generally taxed as ordinary income at exercise.
- Quarterly estimated tax: under IRC Section 6654(d)(1)(B), if prior-year AGI exceeded $150,000 ($75,000 if married filing separately), the safe harbor is 110% of the prior year's tax (rather than the usual 100%).
8. Small Business / 小企业
LLC vs. S公司与主页办公室扣除
- LLC(有限责任公司)与S公司(S corp)的选择,会影响自雇税、合理薪资要求及行政成本,应在成立实体前评估。
- 独资经营者通常在Schedule C申报业务收入;是否改设实体应结合具体收入水平与业务结构评估。
- 依据第280A条,主页办公室扣除要求该区域须为定期、专属的业务使用场所。
LLC vs. S corp and the home office deduction
- The choice between an LLC and an S corporation affects self-employment tax, reasonable-compensation requirements, and administrative cost. Evaluate before the entity is formed.
- Sole proprietors generally report business income on Schedule C; whether to switch to an entity depends on income level and business structure.
- Under IRC Section 280A, the home office deduction requires the space to be used regularly and exclusively for business.

Frequently Asked Questions / 常见问题
When is my U.S. federal tax return due?
Form 1040 is generally due April 15. An automatic extension to October 15 is available by filing Form 4868, but the extension is for filing paperwork, not for paying tax owed. Any balance due is still expected by April 15 to avoid penalties and interest.
我在中国的银行账户需要申报FBAR吗?
如果您是美国税务居民,并且您在海外(包括中国)的金融账户总额在一年中的任何时点超过一万美元,您需要提交FBAR(FinCEN Form 114)。这个门槛是所有海外账户的总和,不是单个账户的金额,依据31 CFR 1010.350。
What is the difference between FBAR and Form 8938?
FBAR (FinCEN Form 114) is a FinCEN filing under 31 CFR 1010.350 with a $10,000 aggregate threshold, filed separately from your tax return. Form 8938 is an IRS filing under IRC Section 6038D (FATCA), filed with Form 1040, with higher thresholds that vary by filing status and residency ($50,000/$75,000 single; $100,000/$150,000 married filing jointly, as of tax year 2025). Many taxpayers with China-based accounts must file both.
Are Chinese mutual funds or investment-linked insurance products PFICs?
Many Chinese mutual funds, ETFs, and investment-linked insurance wrappers meet the definition of a Passive Foreign Investment Company under IRC Section 1297. Without a timely Qualified Electing Fund election under Section 1295, gains and certain distributions are taxed under the excess distribution regime of Section 1291, which is generally far more punitive than ordinary capital gains treatment. Each holding should be evaluated individually by a qualified tax advisor.
What if I never filed FBAR and my past non-compliance was not willful?
The IRS Streamlined Filing Compliance Procedures allow taxpayers whose past non-compliance was non-willful to catch up with reduced penalties. The Streamlined Domestic Offshore Procedures (SDOP) apply to U.S. residents and carry a 5% miscellaneous offshore penalty on the highest aggregate account balance. The Streamlined Foreign Offshore Procedures (SFOP) apply to taxpayers who meet a non-residency test and carry no offshore penalty. Whether facts support the non-willful standard is a determination that should be made with a qualified tax advisor.
