Global Tax Transparency Upgraded: How CRS 2.0 Will Affect Chinese Tax Residents

Editor's Note:Against the backdrop of deepening global tax transparency, the automatic exchange of financial account information for tax purposes is entering a new phase of development. In 2023, the Organisation for Economic Co-operation and Development (OECD) released a revised version of the Common Reporting Standard (CRS), commonly referred to as CRS 2.0. The updated framework introduces significant adjustments to the scope of reportable assets, reporting financial institutions, and due diligence requirements.

Although CRS 2.0 has not yet been formally implemented in mainland China, several major international financial centers have already begun promoting the adoption of the new rules. As a result, the transparency of overseas financial assets held by Chinese tax residents may increase further. This article briefly reviews the key differences between CRS 1.0 and CRS 2.0 and analyzes the potential implications for Chinese tax residents.

I. The Upgrade of the CRS System: A New Stage of Global Tax Information Exchange

In recent years, with the continuous increase in cross-border capital flows, tax authorities worldwide have intensified their focus on combating cross-border tax evasion. In this context, the CRS framework developed under the leadership of the OECD has gradually become a fundamental pillar of global tax information exchange.

Under the CRS framework, financial institutions are required to identify the tax residency of account holders and report relevant financial account information to their domestic tax authorities. These authorities then automatically exchange such information with tax authorities in other participating jurisdictions. The CRS is widely regarded as one of the key pillars of the global anti-tax evasion framework, alongside the Foreign Account Tax Compliance Act (FATCA), forming a cornerstone of international tax transparency.

China began implementing the automatic exchange of financial account information under the CRS framework in 2018 and has since conducted exchanges with numerous jurisdictions. As the system has gradually matured, CRS has played an important role in enhancing global tax transparency.

However, rapid developments in financial technology and digital assets have revealed certain limitations in the traditional CRS framework. For example, some digital asset trading platforms and electronic money accounts were not fully covered under the original CRS rules.

To address these challenges, the OECD released revisions to the CRS in 2023 and simultaneously introduced the Crypto-Asset Reporting Framework (CARF), which specifically targets the reporting of digital assets. The integration of CRS 2.0 with CARF reflects the effort to adapt the global tax information exchange system to the evolving digital financial environment.

II. Key Differences Between CRS 1.0 and CRS 2.0

Compared with CRS 1.0, CRS 2.0 introduces several important changes aimed at expanding the scope of reporting and strengthening transparency. The key updates include the following aspects.

1. Introduction of Reporting Requirements for Digital Assets

CRS 1.0 primarily targeted traditional financial accounts, such as bank accounts, securities accounts, fund holdings, and certain insurance products. However, with the rapid growth of crypto-assets, a significant portion of wealth is now held in digital form, which was not fully addressed under the original CRS framework.

CRS 2.0 introduces reporting requirements related to digital assets and works in coordination with CARF. Under the revised system, certain digital asset service providers may fall within the reporting framework.

CRS 2.0 mainly extends the scope of the existing CRS rules to cover electronic money and central bank digital currencies, while CARF functions as a separate framework specifically designed to regulate decentralized crypto-asset transactions. In the future, crypto-asset trading platforms and custodial service providers may be required to identify the tax residency of their users and report relevant information to tax authorities.

As a result, digital assets—which were previously outside the traditional tax reporting system—are gradually being incorporated into the global tax transparency framework.

2. Expansion of the Scope of Reporting Financial Institutions

CRS 2.0 also expands the scope of reporting entities by incorporating certain emerging financial service providers, such as electronic money institutions and some digital investment platforms.

In addition, the revised framework reassesses certain financial products previously considered to be low-risk. The classification of certain insurance products and investment instruments has also been refined in order to reduce interpretative ambiguities for financial institutions.

Through these revisions, the CRS framework will cover a broader range of financial assets, thereby reducing the possibility of avoiding reporting obligations through financial product structuring.

3. Strengthening of Due Diligence and Look-Through Rules

Under CRS 1.0, some account holders structured their financial holdings through offshore companies, trusts, or investment funds, which in practice could make the ultimate beneficial owner less transparent.

CRS 2.0 introduces targeted revisions to address this issue by strengthening the identification requirements for Passive Non-Financial Entities (Passive NFEs) and their controlling persons. Financial institutions are required to perform more robust due diligence in order to identify the ultimate controlling individuals.

This means that even if financial accounts are held through companies or trust structures, the information of the ultimate tax resident controlling the entity may still be identified and exchanged through the CRS system.

4. Higher Standards for Financial Institution Due Diligence

CRS 2.0 further raises the compliance requirements for financial institutions in areas such as customer identification, tax residency determination, and information collection.

These updates include optimizing tax residency identification rules, strengthening the verification of self-certifications provided by account holders, and introducing additional checks for inconsistent or abnormal information.

As a result, financial institutions will face stricter compliance obligations in account onboarding, customer due diligence, and annual reporting processes.

III. Potential Impacts of CRS 2.0 on Chinese Tax Residents

It is worth noting that CRS 2.0 has not yet been formally implemented in mainland China according to currently available public information. However, several international financial centers have already begun promoting the adoption of the updated framework.

For example, jurisdictions such as the Cayman Islands, Singapore, and Hong Kong have announced plans to implement CRS 2.0 or related frameworks in the coming years. Given that many Chinese tax residents hold financial accounts in these jurisdictions, the implementation of the new rules may still have practical implications.

If Chinese tax residents maintain financial accounts in jurisdictions that have adopted CRS 2.0, local financial institutions will be required to collect and report relevant information under their domestic regulations. Such information may subsequently be exchanged with the Chinese tax authorities through the CRS information exchange network.

The potential impacts may include the following.

1. Increased Transparency of Overseas Assets

CRS 2.0 expands the scope of reportable financial accounts and enhances the ability to identify complex ownership structures. As a result, asset-holding arrangements involving offshore companies, trusts, or investment funds may become more transparent under the information exchange framework.

For Chinese tax residents holding overseas bank accounts, investment accounts, or other financial assets, the likelihood that such information will be exchanged with Chinese tax authorities may increase.

2. Digital Assets Enter the Regulatory Scope

With the introduction of digital asset reporting rules, the anonymity previously associated with crypto-assets in cross-border asset allocation may gradually diminish.

If digital asset platforms or custodial institutions operate in jurisdictions implementing CRS 2.0 or CARF, transaction information related to account holders may fall within the reporting scope.

This indicates that digital assets are no longer entirely outside the traditional international tax information exchange system.

3. Historical Asset Structures May Require Reassessment

Some taxpayers previously structured their cross-border assets based on the regulatory environment under CRS 1.0, for example by using offshore entities or multi-layer investment structures.

With the strengthened look-through rules under CRS 2.0, such structures may require reassessment. In a more transparent information exchange environment, overly complex structures lacking substantive commercial purposes may face increasing tax compliance risks.

IV. Risk Alerts and Compliance Recommendations

Against the broader trend of increasing global tax transparency, the introduction of CRS 2.0 further demonstrates that tax authorities worldwide are strengthening cross-border asset supervision through international cooperation.

For Chinese tax residents, the following compliance measures may help mitigate potential risks.

1. Conduct a Comprehensive Review of Overseas Asset Structures

Taxpayers should systematically review their overseas asset holdings, including:

• overseas bank accounts
• investment accounts and securities assets
• offshore companies or trust structures
• digital asset accounts

A clear understanding of existing asset structures can help identify potential reporting and tax compliance risks.

2. Monitor Implementation Developments Across Jurisdictions

Because CRS rules are implemented through domestic legislation in each participating jurisdiction, the timing and details of implementation may vary.

Taxpayers with financial assets in major financial centers such as Singapore, Hong Kong, or the Cayman Islands should pay particular attention to local CRS 2.0 implementation timelines and reporting requirements.

For instance, Hong Kong is expected to conduct its first CARF exchange in 2028, while Singapore is planning its first CRS 2.0 information exchange in the same year.

3. Ensure Consistency Between Tax Filings and Asset Information

As international information exchange mechanisms become more sophisticated, tax authorities are increasingly capable of obtaining overseas financial account information.

Taxpayers should ensure that their personal income tax filings and other tax declarations accurately reflect their overseas income and assets to avoid potential tax disputes arising from information discrepancies.

4. Seek Professional Advice When Necessary

Cross-border asset arrangements often involve complex tax rules, particularly when multiple jurisdictions are involved.

For individuals with complex asset structures or substantial overseas investments, it is advisable to seek professional advice from tax advisors or legal counsel to conduct compliance assessments and develop more robust tax planning strategies.

Conclusion

As global tax transparency continues to strengthen, cross-border asset allocation is no longer purely an investment matter but also a significant tax compliance issue.

For Chinese tax residents, it is essential to understand relevant international tax rules and information exchange mechanisms when making overseas investment arrangements and to fulfill their tax reporting obligations in accordance with the law. Where offshore companies, trusts, or other complex investment structures are involved, professional tax or legal advice should be sought to reduce potential compliance risks.
