Hong Kong Passes Law Implementing OECD Crypto Reporting Rules
Hong Kong has passed legislation implementing the OECD's CARF, obliging crypto service providers to collect and report transaction data starting in 2027.

Hong Kong has passed legislation that implements the OECD's Crypto-Asset Reporting Framework (CARF). Under the new law, crypto service providers will have to collect and report transaction data, with the obligations applying from 2027.
What the law does
CARF is the OECD's international standard for the exchange of information on crypto-asset transactions. By transposing it into local law, Hong Kong commits to a regime in which firms that provide crypto services gather data on their users' activity and pass it on in a standardised way. The legislation sets 2027 as the starting point for this collection and reporting.
The move places Hong Kong's crypto industry inside a global tax-transparency effort that treats digital assets in a similar way to traditional financial accounts, where reporting between jurisdictions is already routine.
Why it matters
For exchanges, brokers and other service providers operating in the city, the change means preparing systems and processes well ahead of the deadline. Gathering and reporting transaction data is an operational task that typically requires adjustments to onboarding, record-keeping and compliance workflows.
For users, the practical effect is greater visibility of crypto activity to tax authorities. Hong Kong has positioned itself as a hub for digital-asset businesses, and aligning with an OECD standard signals that this ambition is to be pursued alongside international transparency expectations.
What comes next
With the bill passed, attention turns to implementation. Providers have until 2027 to get ready, and further details on how the rules will be applied in practice will matter for how smoothly the transition goes.
