Protocols & Policy · Crypto tax reporting
Hong Kong's legislature passed a law requiring crypto platforms to collect users' tax details from 2027 for the tax department to share with partner jurisdictions starting in 2028, the government said.
Crypto platforms serving customers in Hong Kong will have to collect each user's tax details and transaction totals for the city's tax department to send to foreign tax authorities, under a law the Legislative Council passed on Nov. 4, the government said [1]. The law brings in the OECD's Crypto-Asset Reporting Framework, or CARF, a standard under which tax authorities swap crypto account information each year, and updates the Common Reporting Standard, or CRS, the existing standard for swapping bank and investment account data [1].
The Inland Revenue (Amendment) (Crypto-Asset Reporting Framework and Amended Common Reporting Standard) Bill 2026 was gazetted on May 22, according to the Inland Revenue Department (IRD) [3]. It is a reporting law, not a tax: it sets what platforms must collect and pass on. Under the bill as published, the reporting duties start on Jan. 1, 2027 [2].
Under the bill as published, the crypto part "comes into operation on 1 January 2027" and the amended CRS part on "1 January 2028" [2]. The government said the IRD will exchange CARF information with partner jurisdictions "starting from 2028" and amended-CRS information "starting from 2029," and that exchanges will be "on a reciprocal basis" [1].
Each return from a reporting crypto-asset service provider must give, for an individual user, "the name, address, jurisdiction of residence, TIN and the date and place of birth" [2]. A TIN is a taxpayer identification number. For each type of crypto-asset, the return must also give aggregate amounts, units and the number of transactions for purchases and sales against fiat currency, among other categories [2]. The IRD says the amended CRS adds central bank digital currencies, specified e-money, derivatives referencing crypto-assets and investment entities that invest in crypto [3].
Penalties fall on the platforms. A provider that fails, "without reasonable excuse," to register, carry out due diligence or file a return commits an offense punishable by a level 3 fine [2]. Continuing failures to register, file a return or comply with a notice add HK$500 a day after conviction [2]. For due-diligence failures and materially incorrect returns, the fine is a level 3 fine or HK$1,000 per user, or per controlling person behind a user account, who is the subject of the offense, "whichever is the higher" [2]. These terms come from the bill as published; Le Coin has not obtained the enacted text, so any amendments made before passage are not reflected.

Hong Kong is not alone. The OECD's Global Forum list, last updated Sept. 14, 2026, places Hong Kong (China) among jurisdictions "undertaking first exchanges by 2028" [4].
| First exchanges by | Jurisdictions |
|---|---|
| 2027 | 46 |
| 2028 | 27, including Hong Kong (China) |
| 2029 | 4, including the United States |

Secretary for Financial Services and the Treasury Christopher Hui said aligning with the standards "will reinforce the confidence of crypto-asset service providers, financial institutions and digital asset users in operating and making long-term investments in Hong Kong" [1].
A data-sharing law only shares data with partners that exchange back, and the government frames Hong Kong's exchanges as reciprocal [1]. The OECD's list is a list of commitments, not of laws in force, and the bill leaves the amount of a level 3 fine to other legislation.
In Le Coin's view, the cost lands on the platforms, not the holders. The bill's per-user fine scales with a provider's customer base, which makes due diligence a compliance line item for any exchange that wants Hong Kong users, and the collection starts a year before any exchange does.
