Hong Kong Strengthens Its AEOI Framework with New Compliance Measures

Hong Kong has strengthened its framework for the Automatic Exchange of Information (AEOI) through legislative amendments approved by the Legislative Council in June 2026. The updated provisions reinforce the jurisdiction’s alignment with the OECD’s Common Reporting Standard (CRS) and reflect recommendations arising from the OECD peer review process.

Since implementing the CRS in 2018, Hong Kong has participated in the international exchange of financial account information with partner jurisdictions, supporting global initiatives aimed at enhancing tax transparency and combating cross-border tax evasion.

The legislative amendments focus on reinforcing the administrative aspects of the existing AEOI regime rather than changing the underlying reporting framework. Among the key measures introduced are mandatory registration requirements for reporting financial institutions, enhanced record-keeping obligations and a strengthened penalty regime for cases of non-compliance. Together, these measures are intended to improve the efficiency, consistency and integrity of the reporting system.

The updated framework will enter into force on 1 January 2027. Prior to its implementation, the Inland Revenue Department is expected to publish additional guidance and technical information to support financial institutions in meeting the new administrative requirements.

Practical implications

Financial institutions operating in or through Hong Kong should use the implementation period to review their existing AEOI governance, internal reporting procedures and documentation policies. Although the amendments do not introduce new CRS reporting obligations, they increase the administrative expectations placed on reporting entities and reinforce the importance of maintaining effective compliance controls.

The reform highlights Hong Kong’s continued commitment to international tax transparency and demonstrates its intention to remain fully aligned with evolving OECD standards governing the automatic exchange of tax information.
