Hong Kong has approved new cryptocurrency reporting legislation that will require qualifying exchanges and digital asset service providers to collect customer tax information and report transaction records from January 1, 2027. The framework will also enable the city to exchange cryptocurrency-related financial information with participating foreign tax authorities beginning in 2028.
The Legislative Council approved the Organisation for Economic Co-operation and Development's (OECD) Crypto-Asset Reporting Framework, according to a government announcement on November 4. The legislation establishes standardized disclosure requirements for cryptocurrency businesses operating within Hong Kong's jurisdiction.
The new rules cover cryptocurrency purchases, sales, exchanges and transfers involving external wallets. They require affected providers to collect customer identification details and submit relevant transaction information to Hong Kong's Inland Revenue Department.
Hong Kong Crypto Exchanges Face New Registration Requirements
From January 1, 2027, qualifying cryptocurrency service providers must register with the Inland Revenue Department. The requirements apply to businesses based on their incorporation, management or operational connections to Hong Kong.
Companies will also need to gather customer information, including residential addresses, tax residency details, identification numbers and dates of birth. Providers must verify customers' tax residency to determine whether their transactions fall within the scope of international reporting obligations.
Existing customers will be subject to updated documentation requirements, while new users must provide the relevant declarations during account onboarding. The collected information will help authorities identify reportable activity involving customers from participating jurisdictions.
International Crypto Data Sharing Begins in 2028
Hong Kong plans to begin exchanging cryptocurrency transaction information with participating foreign tax authorities in 2028. The arrangement follows international reporting standards intended to improve transparency and strengthen tax compliance across digital asset markets.
The legislation does not introduce a new cryptocurrency transaction tax or change existing tax rates. Instead, the reporting system is designed to help authorities monitor compliance with tax obligations already in place across participating jurisdictions.
The government said international information exchanges would operate under confidentiality and data security protections. A separate list of participating jurisdictions will be published as implementation arrangements progress.
Hong Kong Also Updates Broader Financial Reporting Standards
The Legislative Council also approved amendments to the existing Common Reporting Standard, which governs the automatic exchange of financial account information. The changes will take effect in 2028, with international exchanges under the amended framework scheduled to begin in 2029.
Hong Kong has participated in automatic exchanges of financial account information since 2018. The latest amendments extend the city's reporting framework, while the newly approved crypto rules establish separate obligations for digital asset service providers.
Financial Services and the Treasury Secretary Christopher Hui highlighted the role of international reporting standards in supporting confidence in financial markets. The government expects stronger transparency requirements to improve compliance among financial institutions and digital asset businesses.
The Inland Revenue Department has also established a dedicated task force to help affected companies prepare for the new requirements. The team will provide implementation guidance and address technical questions from cryptocurrency service providers.
Project Ensemble Adds to Hong Kong's Digital Finance Initiatives
Separately, Hong Kong has introduced round-the-clock settlement for tokenized deposits through Project Ensemble. The initiative supports blockchain-based transactions among participating banks and forms part of the city's broader efforts to develop digital financial infrastructure.
The approved crypto reporting legislation follows a phased implementation schedule. Service providers must prepare to collect and report customer information from 2027, while cross-border exchanges of cryptocurrency-related data are expected to begin in 2028.
