Hong Kong Adopts OECD Crypto Reporting Rules, With Data Gathering From 2027

Legislators in Hong Kong approved a bill on Wednesday that extends global crypto tax reporting rules to the city. From 2027, service providers will begin gathering user data.

With that vote, Hong Kong joins a group of Asian hubs that are competing to make crypto tax reporting more transparent.

Hong Kong Takes On the OECD’s Crypto Tax Reporting Standard

The Crypto-Asset Reporting Framework, known as CARF, is an OECD standard built around tax transparency. Under it, countries swap details of crypto-asset transactions automatically each year.

On November 4, the city’s Legislative Council approved the Inland Revenue Amendment Bill 2026. That legislation puts CARF into effect, together with the most recent changes to the Common Reporting Standard, or CRS.

Relevant service providers are required under the new regime to start collecting specified information in 2027.

Hong Kong’s first CARF exchanges with partner jurisdictions will then get under way in 2028.

Hong Kong Passes Crypto Tax Reporting Law, With Data Collection Starting in 2027

The amended CRS, for its part, applies from 2028 and widens coverage to digital financial products. Automatic exchanges under that updated standard come in 2029. Hong Kong has, notably, been exchanging financial account information under the CRS since 2018.

Christopher Hui, Secretary for Financial Services and the Treasury, said the alignment would “reinforce the confidence of crypto-asset service providers.” A dedicated team has also been formed by the Inland Revenue Department to guide the industry.

Where Else in Asia Are Crypto Tax Rules Getting Tighter?

A number of Asian financial centres are heading the same way. Singapore, for one, published its CARF regulations in August 2026.

From January 1, 2027, new users in Singapore must supply their tax residency and identification number under those rules. Platforms there will also be barred from executing trades for users who lack valid self-certification from 2028.

South Korea and Japan are likewise among the jurisdictions that have pledged to start CARF exchanges by 2027. Australia has committed to the same.

Tax authorities across the region will therefore examine crypto investors much more closely. Exchanges, in turn, will need stronger due diligence and reporting systems in order to comply.

In practice, yearly data on users’ crypto transactions will land with tax authorities. Investors who hold accounts abroad may thus find hiding gains far harder.

The shift could, however, give institutional confidence a lift. Regulated players are often drawn in by clear tax rules, which fits Hong Kong’s ambition of becoming a leading digital asset hub.
