Introduction
In 2026, global tax information exchange will enter the era of CRS 2.0. To address the rapid development of asset forms in the digital economy, the Organisation for Economic Co-operation and Development (OECD) officially released the revised Common Reporting Standard (CRS 2.0) in 2023. Compared to version 1.0, CRS 2.0 strengthens due diligence procedures, enhances tax residency verification requirements, formally includes digital assets such as central bank digital currencies and specific electronic money products into the reporting scope, filling regulatory gaps in the digital finance era and further promoting international tax transparency.
Currently, multiple jurisdictions have designated 2026 as a critical milestone for the implementation of CRS 2.0 and are advancing local legislation and updating supporting measures. Among them, the British Virgin Islands and the Cayman Islands will be the first to implement CRS 2.0 rules starting January 1, 2026. Hong Kong, China, launched a public consultation on the proposed CRS 2.0 rules on December 9, 2025, and plans to complete legislative revisions within the year. As a key participant in CRS, China, leveraging the digital upgrades of the "Golden Tax Phase IV" system and foreign exchange supervision, has reserved sufficient technical space to align with the 2.0 standard. For relevant individuals and reporting institutions, the corresponding tax compliance preparations have entered a critical window period. This article systematically outlines the main changes and core impacts of CRS 2.0 based on its revised content and latest administrative practices, while providing potential guidance for affected individuals and institutions.
1 Revision Background of CRS 2.0
For a long time, crypto assets have existed outside the purview of traditional tax supervision. Although the CRS 1.0 standard, introduced in 2014, established a mechanism for the automatic exchange of global tax information, it gradually exposed systemic flaws with the development of the Web3 market—the old rules primarily defined financial assets based on traditional custody models. As long as crypto assets were stored in non-custodial cold wallets or circulated on decentralized exchanges, they could remain outside the existing reporting system. The significant loss of tax base has drawn high attention from governments and international organizations.
To address this issue, the OECD adopted a dual-track strategy: on one hand, introducing the dedicated Crypto-Asset Reporting Framework (CARF) to facilitate information exchange for decentralized and non-traditional financial intermediary crypto transactions; on the other hand, using CRS 2.0 as a supplement to achieve a closed regulatory loop. Specifically, CRS 2.0 incorporates electronic money, central bank digital currencies, and other assets with traditional financial attributes into the already mature CRS exchange network. This not only narrows the tax "gray areas" brought about by financial digital transformation but also marks the upgrade of the global tax information exchange system for the digital economy era, ensuring that major financial asset categories remain within the CRS reporting scope.
2 Analysis of Key Revisions: What Has CRS 2.0 Updated?
CRS 2.0 is not merely a targeted supplement for crypto assets but a systematic iteration of the global tax information exchange standards. Its core purpose is not only to eliminate the regulatory boundaries between digital financial assets and traditional financial assets, ensuring consistent reporting outcomes, but also to fill compliance gaps caused by previously ambiguous technical definitions and enhance international tax transparency. According to the new rules, the improvements of CRS 2.0 over version 1.0 mainly focus on the scope of information reporting, due diligence requirements, and the exchange of information on dual tax residents.
2.1 Broadening the Scope of Information Reporting
CRS 2.0 expands the scope of reportable information to include emerging digital financial products. First, it incorporates financial products such as "specific electronic money products" and "central bank digital currencies" into the CRS reporting scope, while modifying the definitions of depository institutions and deposit accounts to include electronic money service providers and the electronic money accounts they maintain. Second, it includes indirectly held crypto assets in reporting. The revision of the "Investment Entity" definition achieves comprehensive coverage of indirect holding paths for crypto assets. If financial accounts hold financial products linked to crypto assets, such as crypto derivatives or fund shares for cryptocurrency investment purposes, they will also be subject to due diligence and reporting procedures under the CRS framework. Third, in addition to the key identification information of account holders and controllers and financial account transaction information, reporting institutions need to supplement reports with other relevant details, including identifying joint accounts, financial account types, and the due diligence procedures applied, to promote tax compliance.
2.2 Strengthening Due Diligence Requirements
CRS 2.0 further strengthens the quality of information and reliability of sources for due diligence on the existing basis. First, in cases where valid self-certification is not obtained, reporting institutions need to conduct exceptional due diligence procedures to ensure effective reporting for such accounts. Second, CRS 2.0 introduces a government verification service, proposing to allow reporting institutions to directly obtain confirmation of a taxpayer's identity and unique tax residency identifier from the tax authority of their residence. Currently, reporting institutions primarily conduct due diligence based on AML/KYC documents, user self-certifications, and other account information collected by the reporting institutions. This measure will enhance the reliability of due diligence results.
2.3 Achieving Comprehensive Exchange of Information for Dual Tax Residents
In reality, the holder of an entity or individual account may have tax residency in two or more jurisdictions. Under the original CRS framework, such dual or multiple residency individuals could use conflict resolution rules to determine a specific residency for self-certification. This might lead to account holders being prematurely identified as tax residents of a single jurisdiction, resulting in relevant information not being reported to other jurisdictions. In this context, CRS 2.0 requires account holders to declare all their tax residencies during the self-certification process. Through a "full exchange" mechanism, CRS information about the account can be simultaneously shared with all relevant jurisdictions. This means that for high-net-worth individuals with dual residency or complex cross-border asset allocations, stricter tax residency verification mechanisms will reduce their room for selective reporting across different jurisdictions.
3 Impact Assessment and Response Strategies
3.1 For Investors
For investors, the regulatory havens previously constructed using geographic arbitrage or non-custodial wallets will become unsustainable. In the future, they will inevitably face challenges such as penetrating reviews of tax-related information and full information exchange with multiple tax residency jurisdictions, significantly increasing their tax compliance costs. Especially for holders of digital financial assets or cryptocurrencies, under the interaction of the revised CRS rules and the CARF framework, such investments have been fully incorporated into the tax information exchange and collection frameworks of various countries.
To address the new regulatory requirements, high-net-worth individuals holding large amounts of crypto assets can focus on the认定规则 (determination rules) regarding "tax residency" under the new regulations. The path of relying solely on a foreign passport without substantive evidence of local residence (such as utility payment records) and simply using documentation to isolate tax risks is no longer viable. The focus of compliance must return to the genuine alignment of life and economic interests, optimizing offshore and onshore structures to achieve effective asset isolation and risk stratification.
Secondly, if investors are unable to provide complete and coherent original cost vouchers due to frequent on-chain interactions, multi-platform operations, or missing historical records, tax authorities may, for anti-avoidance considerations, assess their taxable profits in a manner unfavorable to the taxpayer during audits. Investors may consider using professional financial and tax tools to review existing reporting records and financial account information, complete tax self-inspections, prepare for supplementary declarations, and build an audit-ready compliance ledger.
3.2 For Institutions with Reporting Obligations
According to CRS 2.0, industry institutions such as electronic money service providers will also be included in the category of reporting entities and must proactively perform due diligence and information reporting obligations for their users. Furthermore, all Reporting Financial Institutions face stricter due diligence requirements and a broader scope of information reporting. This necessitates that reporting institutions upgrade their underlying infrastructure systems used for reporting and complete the supporting updates to their information collection, verification, and reporting systems before the new regulations take effect in their respective jurisdictions. Failure to fully fulfill obligations under CRS 2.0 may trigger strict penalty measures for reporting institutions and related responsible persons, leading to greater economic and reputational losses.
In response, reporting institutions can, on one hand, proactively deploy technical systems that meet CRS 2.0 requirements to handle complex auditing and data reporting needs. For instance, these systems can be enhanced in identifying and labeling specific aspects like complex transaction types, joint accounts, and financial account types. On the other hand, reporting institutions should closely monitor relevant legislative developments in their jurisdictions to understand local regulations and respond effectively in a timely manner. CRS 2.0 requires domestic legislative transformation in various countries to become legally binding, and the implementation timelines and specific details of the rules may differ across jurisdictions. Therefore, in addition to paying attention to the common provisions issued by the OECD, reporting institutions and their staff should particularly focus on the implementation progress and specific provisions of local legislation.
Conclusion
The year 2026 has arrived, and CRS 2.0 along with the CARF framework are being gradually implemented worldwide. Under the升级 (upgrade) of the international tax information exchange system and the encirclement of penetrating tax collection and management by tax authorities, the era of隐匿 (concealment) for Web3 wealth has become a thing of the past. The new CRS regulations not only tangibly affect the reporting requirements of Reporting Financial Institutions but also impose higher tax supervision demands on cross-border investors. Rather than waiting for risks to materialize amidst uncertainty, it is better to proactively complete the compliance transformation during the policy window period. After all, in the CRS 2.0 era, visible compliance is often safer than an invisible asset "cloak".
