Legislative approval and timeline

On November 4, Hong Kong's Legislative Council passed a crypto tax‑information reporting bill that creates the Crypto‑Asset Reporting Framework (CARF).

The bill requires covered crypto‑asset service providers to start collecting user and transaction data on January 1, 2027, ahead of the Inland Revenue Department’s first international exchange in 2028.

The government also adopted the amended Common Reporting Standard, which will take effect in 2028 with cross‑border data sharing beginning in 2029, a schedule that runs parallel to CARF.

Scope of reporting obligations

CARF targets businesses that act as counterparties or intermediaries in crypto‑fiat exchanges and platforms that enable direct crypto‑crypto trades.

Providers must identify reportable users and controlling persons based on tax residence in jurisdictions covered by the framework, then gather identifying details, residence information, and aggregated transaction data.

Obligations vary according to each provider’s nexus with jurisdictions defined in the framework, meaning some firms may face limited reporting while others must submit comprehensive data.

Implementation mechanisms

The Inland Revenue Department will develop a dedicated CARF reporting portal and publish a data schema that specifies the format for annual submissions.

A technical support team has been established to answer industry queries, and guidance documents will be released before the 2027 collection year.

The department emphasizes that exchanges with partner jurisdictions will be reciprocal, subject to confidentiality and security safeguards.

Context from recent regulatory activity

The tax reporting bill follows other Hong Kong initiatives aimed at strengthening financial resilience, such as the post‑quantum cryptography assessment toolkit announced by the Hong Kong Monetary Authority and HKUST on November 2.

While the toolkit focuses on banks, both measures illustrate the city’s broader push to modernise its regulatory infrastructure ahead of emerging technological risks.

Industry reaction and next steps

Crypto‑asset service providers are preparing compliance programs to meet the 2027 data‑collection deadline, noting that the reporting requirements differ from traditional financial account reporting.

Stakeholders anticipate that the first annual reports will be filed in 2027, with the Inland Revenue Department beginning its international data exchanges in 2028 as scheduled.

The government has not disclosed exact filing dates, leaving providers to monitor forthcoming guidance for precise timelines.

According to Cryptoslate, the CARF framework defines reportable users and controlling persons by their tax residence in jurisdictions covered by the scheme, requiring providers to gather identifying details, tax‑residence information, and aggregated transaction data before the annual filing, a scope not highlighted in the original article.

The Inland Revenue Department will also create a dedicated CARF reporting portal and publish a data schema that specifies the exact format for submissions, and it has set up a technical support team to address industry queries, as noted in the legislative background.

Cryptoslate clarifies that the amended Common Reporting Standard will come into force in 2028 with cross‑border data exchanges beginning in 2029, operating on a separate calendar from CARF’s 2027 collection and 2028 exchange schedule.
