2026年是中国跨境税务监管的"分水岭年"。从7月24日财政部和国家税务总局联合发布21号公告，到CRS 2.0在全球离岸金融中心同步落地，再到国务院837号令首次将居民个人纳入境外投资监管——每一件都足以载入中国跨境税法编年史。
年终了，我们把今年最重要的五件大事系统盘一遍。
一、21号公告：离岸信托个税规则横空出世
这是今年分量最重的一份文件。7月24日，财政部和税务总局联合发布《关于离岸信托个人所得税有关事项的公告》（2026年第21号），中国第一次对离岸信托建立了完整的个人所得税征管规则，覆盖全生命周期，追溯到2023年1月1日。
装入环节：居民个人将财产装入离岸信托，视同财产转让，按市值扣除原值后的余额，按"财产转让所得"征20%个税。
存续环节：信托存续期间的收益，无论是否实际分配，均按年申报缴税。"财产转让所得"和"利息、股息、红利所得"分别计算，不得互相抵减。信托运营费用一律不能扣除。
终止环节：信托终止清算时，对全部清算收益按"利息、股息、红利所得"缴20%。
还有两个容易被忽略的条款：居民个人转为非居民个人时，视同清算，当天结算税负；设立人去世，触发信托财产税务清算。
对存量信托：2023年1月1日起装入财产的未缴税款原则上征收3年；2025年及以前年度未缴的收益分配环节税款，一次性"打包"按"利息、股息、红利所得"申报，90日内缴纳。
穿透课税+费用不可扣除+亏损不结转，这三条合在一起对持有高波动资产的信托打击最大。名义税率20%，但因为亏损不能跨年带走，实际有效税率可能远超20%。
二、CRS 2.0：全球税务透明化进入"深度穿透"阶段
2026年1月1日，开曼群岛和BVI同步启动CRS 2.0数据采集。3月27日，香港政府刊宪条例草案，预计2027年1月1日正式生效。CRS 2.0与1.0的核心区别在于三个"升级"：
加密资产纳入强制申报。CARF框架将比特币、稳定币、NFT、加密衍生品全部纳入。开曼、BVI 2026年已启动，香港2027年启动数据收集，2028年首次跨境交换。
离岸架构强制穿透。被动收入占比超过50%的离岸公司被认定为"空壳实体"，金融机构须逐层穿透至最终受益自然人（持股25%以上强制披露）。信托的委托人、受托人、受益人三类角色信息均须申报。
双重税务居民"二选一"失效。CRS 2.0要求向所有相关税务辖区同步报送。单纯持有海外护照或香港身份证，已不足以规避内地税务申报。
国家税务总局2026年4月发布会明确：境外收入监管从"软性提醒"转为"硬性稽查"，前5个月居民个人境外收入补缴税款超130亿元，同比增幅超40%。
三、837号令：中国首部对外投资行政法规
2026年7月施行的《国务院关于对外投资的规定》（国务院令第837号），是中国第一部专门规范境外投资的行政法规。
最受关注的是第2条第2款："直接或间接获得"境外公司所有权、控制权或经营管理权，均属于法定境外投资行为，必须履行备案手续。七个字——将亲戚代持、员工挂名、SPV多层嵌套全部纳入监管。
首次将居民个人纳入境外投资监管范围。不配合备案的，可能面临最高投资额10‰的处罚、市场禁入、联合信用惩戒，情节严重的依法追究刑事责任。
与CRS 2.0叠加看，两项政策在国际信息交换和境内对外投资法治两个维度同时收紧，跨境监管逻辑完成切换——不看公司注册地，只认实际控制人。
四、ESG合规：全球分化下的中资企业夹缝
2026年全球ESG监管呈现结构性分化：欧盟通过Omnibus I指令大幅缩减CSRD适用范围，美国SEC于5月提议废除气候披露规则。一收一放之间，中资企业面临更复杂的合规环境。
欧盟CSDDD正式生效，中国出口商和在欧子公司面临域外合规高压。Scope 3（价值链上下游间接排放）的数据穿透与举证，是引发数据主权冲突与合规成本激增的核心战场。
国内层面，837号令虽无直接ESG条款，但第5条和第16条为ESG合规预留了解释空间。有专业团队提出将ESG合规作为837号令投资监管的"第五维度"嵌入投资全流程，这个思路值得关注。
ESG数据跨境是另一个痛点。碳排放监测数据可能属于"重要数据"，需出境安全评估；员工个人信息属敏感个人信息，需单独同意+标准合同。企业向境外ESG评级机构披露供应链数据时，可能因数据出境安全评估未获批而构成违法。
五、中亚投资协定升级：法律护身符加码
2025年6月，中国与哈萨克斯坦签署新版投资保护协定，替换沿用三十余年的1992年旧版。2026年哈议会批准。新协定明确写入防止任意征收、公平平等待遇等核心条款，并确立国际仲裁机制。
数据印证了这一法律升级的必要性：2025年中国对哈FDI达28亿美元，较2024年的11.9亿美元激增约2.4倍。二十年间累计投资总额293亿美元，双边贸易额2025年达341亿美元。
中亚五国的双边投资保护协定普遍需要更新。20世纪末签订的协定对投资定义过于模式化、最惠国待遇范围不明确、争端解决条款不够完善。推动修订是保障中资企业权益的底层工程。
结语：信息差时代落幕，合规红利显现
2026年的五件大事指向同一个方向：全球170多个税务辖区的数据通道正在打通，离岸架构的"隐身效应"正式终结。后续的红利不在"如何不被发现"，而在"如何稳定合规"。
37号文需在向SPV出资前完成登记，逾期后各地外管局实操中基本不受理补办。这个提醒在837号令出台后更加重要——新规将个人境外投资纳入法定监管，叠加37号文的登记要求，架构搭建的时点把控比以往任何时候都关键。

English version（英文版）
2026 is a watershed year for China's cross-border tax regulation. From the joint Announcement No. 21 of 2026 issued by the Ministry of Finance and the State Taxation Administration on July 24, to CRS 2.0 rolling out across global offshore financial centers, to State Council Decree No. 837 bringing resident individuals into outbound investment regulation for the first time—each one of these deserves a chapter in the chronicle of Chinese cross-border tax law.
As the year ends, here is a systematic review of the five most important events of 2026.
1. Announcement No. 21: The First Personal Income Tax Rules for Offshore Trusts
This is the heaviest document of the year. On July 24, the Ministry of Finance and the STA jointly released the Announcement on Personal Income Tax Matters Concerning Offshore Trusts (Announcement No. 21 of 2026), establishing for the first time a complete individual income tax framework for offshore trusts in China. It covers the full lifecycle and is retroactive to January 1, 2023.
Settlement phase (placement): When a resident individual places assets into an offshore trust, it is treated as a property transfer. The gain (fair market value minus original cost) is subject to a 20% IIT as "income from property transfer."
Holding phase: Income earned by the trust during its lifetime, whether or not actually distributed, must be declared and paid annually. "Income from property transfer" and "interest, dividends, and bonuses" are computed separately and cannot offset each other. Trust operating expenses are not deductible.
Termination phase: Upon termination, the entire liquidation gain is subject to 20% IIT as "interest, dividends, and bonuses."
Two lesser-noticed provisions: when a resident becomes a non-resident, the trust is treated as liquidated and tax is settled on the day; when the settlor dies, the trust's assets are subject to tax liquidation.
For pre-existing trusts: tax on assets placed in after January 1, 2023 is generally collected over 3 years; income-stage tax that was due for 2025 and earlier years can be "bundled" and reported once as "interest, dividends, and bonuses," payable within 90 days.
Look-through taxation + non-deductible expenses + no loss carryforward. Together, these three rules hit hardest at trusts holding high-volatility assets. The nominal rate is 20%, but because losses cannot be carried forward, the effective rate can far exceed 20%.
2. CRS 2.0: Global Tax Transparency Enters the "Deep Look-Through" Era
On January 1, 2026, the Cayman Islands and the BVI simultaneously launched CRS 2.0 data collection. On March 27, Hong Kong published its draft bill, with the framework scheduled to take effect on January 1, 2027. The three "upgrades" of CRS 2.0 over 1.0 are:
Crypto assets in mandatory reporting. The CARF framework brings Bitcoin, stablecoins, NFTs, and crypto derivatives into scope. The Cayman Islands and BVI launched in 2026; Hong Kong will begin data collection in 2027, with the first cross-border exchange in 2028.
Forced look-through of offshore structures. Offshore companies with passive income exceeding 50% are classified as "shell entities"; financial institutions must look through every layer to the ultimate natural beneficiary (mandatory disclosure for any holding of 25% or more). Trustees, settlers, and beneficiaries of a trust must all be reported.
"Two-out-of-one" fails for dual tax residents. CRS 2.0 requires simultaneous reporting to all relevant tax jurisdictions. Holding a foreign passport or a Hong Kong ID is no longer enough to avoid PRC filing.
At the STA's April 2026 press conference, officials confirmed that supervision of foreign-source income has shifted from "soft reminders" to "hard audits." In the first five months, resident individuals made back-tax payments exceeding RMB 13 billion, up more than 40% year on year.
3. State Council Decree No. 837: China's First Outbound Investment Administrative Regulation
Effective July 2026, the State Council Regulation on Outbound Investment (State Council Decree No. 837) is the first dedicated administrative regulation governing overseas investment.
The most-watched clause is paragraph 2 of Article 2: "Directly or indirectly obtaining" ownership, control, or operating rights of an overseas company is a statutory outbound investment and must be filed. Those seven characters sweep in nominee arrangements through relatives, employee shareholdings, and multi-layer SPV structures.
Resident individuals are now covered for the first time. Non-filing may attract fines up to 10‰ of the investment amount, market-entry bans, joint credit sanctions, and—where circumstances are serious—criminal liability.
Read together with CRS 2.0, the two policies tighten simultaneously on two fronts—international information exchange and domestic outbound investment law—completing the switch in cross-border supervision: the place of incorporation no longer matters; only the actual controller does.
4. ESG Compliance: Chinese Companies Caught in a Divided Global Landscape
In 2026, global ESG regulation is structurally divided: the EU passed the Omnibus I directive to sharply narrow the CSRD's scope, while the US SEC proposed in May to repeal its climate disclosure rule. Between tightening and loosening, Chinese companies face a more complex compliance environment.
The EU's CSDDD is now in force, putting Chinese exporters and EU subsidiaries under intense extraterritorial compliance pressure. Scope 3 (indirect emissions across the value chain)—its data look-through and burden of proof—is the central battleground driving data-sovereignty conflicts and surging compliance costs.
Domestically, although Decree No. 837 contains no direct ESG provisions, Articles 5 and 16 leave interpretive room. Some specialist teams have proposed embedding ESG compliance as a "fifth dimension" in the entire outbound investment workflow under Decree No. 837—an approach worth watching.
Cross-border transfer of ESG data is another pain point. Carbon-emission monitoring data may be classified as "important data" and require a security assessment for export; employee personal information is sensitive personal information and requires separate consent and a standard contract. When a company discloses supply-chain data to an overseas ESG rating agency, it may run afoul of the law if the cross-border data security assessment has not been approved.
5. Central Asia Investment Treaty Upgrades: A Stronger Legal Shield
In June 2025, China and Kazakhstan signed a new bilateral investment treaty, replacing the 1992 version that had been in place for over 30 years. The Kazakh parliament ratified it in 2026. The new agreement explicitly includes core provisions on protection against arbitrary expropriation and fair and equitable treatment, and establishes an international arbitration mechanism.
The data underscores why this legal upgrade matters: Chinese FDI into Kazakhstan hit USD 2.8 billion in 2025, a 2.4× jump from USD 1.19 billion in 2024. Cumulative investment over twenty years totals USD 29.3 billion, and bilateral trade reached USD 34.1 billion in 2025.
Bilateral investment treaties across the five Central Asian countries all need updating. The treaties signed in the late 20th century have overly templated definitions of investment, unclear MFN scope, and inadequate dispute-resolution clauses. Pushing for revision is foundational infrastructure for protecting the rights of Chinese firms.
Closing: The Information-Asymmetry Era Is Over; Compliance Pays Off
The five events of 2026 all point in the same direction: data channels between more than 170 tax jurisdictions are being connected, and the "cloaking effect" of offshore structures has formally ended. From here on, the upside is not in "not being discovered" but in "stable compliance."
SAFE Circular 37 registration must be completed before funding the SPV; in practice, local SAFE branches essentially refuse late filings. This reminder is even more important after Decree No. 837, which brings individuals under statutory outbound investment oversight and, stacked on top of Circular 37's filing requirement, makes the timing of any structure setup more critical than ever.
