TL;DR:
The Legislative Council of Hong Kong passed the Inland Revenue (Amendment) Bill 2026 on November 4, 2026, to implement the OECD’s Crypto-Asset Reporting Framework (CARF).
Digital asset service providers must register and begin collecting tax identification and transaction data starting January 1, 2027.
The automatic, reciprocal exchange of tax data with partner jurisdictions will commence in 2028, while the amended Common Reporting Standard (CRS) will take effect in 2028, with initial exchanges scheduled for 2029.
A new regulation on crypto tax reporting was passed this Wednesday by the Legislative Council of Hong Kong. The new rule will require service providers in the sector to register their clients and gather detailed information regarding their transactions starting in 2027.
The legislative measure ratifies the Inland Revenue (Amendment) (Crypto-Asset Reporting Framework and Amended Common Reporting Standard) Bill 2026. Through this framework, the territory adopts the global financial transparency standards designed by the Organisation for Economic Co-operation and Development (OECD).
Moving forward, commercial entities must collect identification details, tax residence, and taxpayer identification numbers from their users. All of this information will be transferred annually to the Inland Revenue Department of Hong Kong (IRD ), which will process the data to share it reciprocally with tax agencies in partner jurisdictions starting in 2028.
The regulation does not introduce a new tax rate on cryptocurrency holdings, nor does it modify existing tax brackets for taxpayers. Its structure is strictly limited to expanding governmental agencies’ operational visibility over digital monetary flows within pre-existing tax rules.
The operational scope of the CARF encompasses intermediaries that facilitate purchase and sale transactions, such as centralized exchanges, brokers, OTC dealers, and crypto asset ATM operators with a presence or nexus in Hong Kong. The regulations cover direct transfers between fiat currencies and digital tokens, exchanges between different crypto assets, and outbound transfers to external wallets.
The framework applies to both fungible digital assets and non-fungible tokens (NFTs) used for payment or investment purposes, expressly excluding central bank digital currencies ( CBDCs ) and specific electronic money instruments.
Implementation Schedule and CRS Amendments
The official timeline establishes that local data collection compliance will take effect on January 1, 2027. Hong Kong authorities scheduled the start of the annual international exchange under the CARF framework for 2028.
Meanwhile, the corresponding revisions to the Common Reporting Standard (CRS)—a framework Hong Kong has applied to traditional financial accounts since 2018—will formally enter into force in 2028. Official documentation states that the first automatic exchanges of financial information under this updated standard will take place in 2029. The statutory text incorporates mutual exclusion clauses to prevent an entity from double-reporting the same transaction under the concurrent CARF and CRS regimes.
The Secretary for Financial Services and the Treasury, Christopher Hui , stated that these measures reflect government efforts to curb cross-border tax evasion and bolster the region’s international standing. According to the official’s remarks, alignment with OECD standards aims to strengthen regulatory certainty for institutional investors and platforms operating long-term within the local Web3 ecosystem.
This approval concludes a legislative process that began with technical consultations between December 2025 and February 2026, reaching lawmakers in its final draft by June following its preliminary gazetting in May.
Despite institutional passage, the actual coverage of these reports remains a subject of ongoing industry debate. Data from a Chainalysis report published in August indicated that potentially taxable crypto transactions globally exceeded $457 billion in 2025. According to the firm’s analysis, transactions within the practical supervisory reach of the CARF framework represented approximately 14% of that activity, leaving the remaining 86% distributed across decentralized protocols, peer-to-peer (P2P) transfers, and on-chain payments operating outside regulated providers.
The Inland Revenue Department of Hong Kong will deploy a dedicated technical team to issue operational guidelines and assist virtual asset service providers in adapting their verification systems. This technical guidance will roll out over the coming year ahead of mandatory operator registration beginning on January 1, 2027.
