The Hong Kong government announced that the Legislative Council passed the bill on November 4, completing the city’s adoption of the OECD’s Crypto Asset Reporting Framework, or CARF. The framework extends the international tax transparency system to digital asset activity, bringing crypto exchanges and other covered providers into a reporting structure designed to help tax authorities identify cross border transactions.
The law separates data collection from international exchange. Under the implementation schedule, providers will begin collecting reportable information on January 1, 2027. Hong Kong’s Inland Revenue Department is scheduled to begin exchanging that information with partner jurisdictions on January 1, 2028, according to the department’s bill information.
That timetable gives firms a limited period to build compliance systems before transaction data begins moving between tax authorities. It also makes Hong Kong a more important link in the emerging global reporting network for digital assets, particularly for customers who use locally licensed platforms while maintaining tax residence elsewhere.
The Inland Revenue Department’s CARF implementation guidance says covered crypto asset service providers will have to conduct customer due diligence and identify information such as a customer’s name, address, tax residence and taxpayer identification number. Providers will also need to record reportable activity and submit annual information to the department.
The transactions covered include exchanges between crypto assets and fiat currencies, exchanges between one crypto asset and another, and transfers to external wallets. That scope means the reporting trail will extend beyond a simple purchase or sale made through a bank-linked account. Crypto to crypto trading and withdrawals to self custody wallets can also become part of the information supplied to tax authorities, where the activity falls within the framework.
For exchanges, the operational challenge is not limited to collecting identity documents. Platforms will need to connect verified customer records with transaction histories that may include transfers to blockchain addresses outside their own systems. They must also determine a customer’s tax residence and maintain that classification across reporting periods, a task that can become more complicated when users relocate or have tax obligations in multiple jurisdictions.
The structure changes the economics of operating a regulated platform in Hong Kong. Exchanges will have to allocate capital to customer onboarding, data storage, compliance staff, transaction classification and annual filings. Those costs may be manageable for large firms with established reporting infrastructure, but they could weigh more heavily on smaller providers and brokers that serve fewer customers or operate across several regulatory regimes.
The legislation also includes amendments connected with the Common Reporting Standard, according to the Inland Revenue Department’s bill page. Together, CARF and the amended standard place digital asset reporting within the wider automatic exchange of information framework, rather than treating crypto as a separate market with different expectations.
The Hong Kong Securities and Futures Professionals Association has been supportive of the framework in principle, but the association and its chairman, Mofiz Chan, raised concerns about implementation. Its concerns include potential record keeping liability after a provider dissolves, penalties applied on a per account basis, tight filing deadlines, and the need for application programming interface reporting and a transition period.
That is the only critical response identified in the sources for this report. No opposing industry view was provided. The association’s position points to a central question for the market: whether Hong Kong’s reporting rules can be implemented without imposing disproportionate costs on smaller participants while still producing reliable information for foreign tax authorities.
For users, the practical effect will be greater visibility into activity conducted through Hong Kong based platforms. For providers, the law makes regulatory compliance part of the capital and infrastructure required to compete in the city’s digital asset market. Hong Kong’s effort to attract crypto liquidity will therefore proceed alongside stricter international scrutiny, not outside it.

Ethan Brooks is not a person. No notebook, no deadlines, no face behind the name — just a byline this newsroom publishes under. Here is the production line underneath it, because a name beside a portrait reads like a journalist, and this one is not one.
The models. Writing: gpt-5.6-luna. Out on the live web: gpt-5.6-luna and gpt-5.6-terra. Pictures: gpt-image-1. Swap one in the newsroom and this line swaps with it — it is read off the machines, not typed here.
How a story is made
- Research. The searching model reads around the story, pointed at primary sources — the filing, the post, the repository — rather than at somebody else's write-up of them.
- Writing. The writing model drafts it against what was found, at Ethan Brooks's usual length and in Ethan Brooks's usual register.
- The loop. A reviewer reads the draft and sends it back with notes. Then reads it again. A piece can go round several times before it leaves the building.
- Enrichment. A quotation has to appear word for word on the page it is taken from. A chart may only use figures that appear in the source it cites. Whatever fails is dropped, and the reason is kept.
- Fact check. A last pass hunts for claims the article makes and its sources do not.
- A human stop. Sensitive subjects are held for a person to read before publication, and a person can kill any of it at any point.
If that sounds less like a newsroom and more like a factory: quite. It is called Press Factory.
