Hong Kong has passed legislation requiring cryptocurrency companies to collect customer transaction information for tax purposes, with the new obligations scheduled to take effect in 2027. The law introduces new compliance requirements covering crypto purchases, sales, token swaps, and transfers to external wallets.

The development was reported by Coin Bureau, which described the legislation as a significant regulatory change for cryptocurrency businesses operating in the financial hub. Under the new requirement, crypto firms will need to collect information on a broader range of customer transactions rather than focusing exclusively on conventional buying and selling activity.

Crypto Transactions Covered by the New Law

The legislation specifically covers four categories of cryptocurrency activity:

• Buying digital assets
• Selling cryptocurrencies
• Exchanging one token for another
• Transferring funds to external wallets

The inclusion of token swaps means that transactions involving exchanges between different cryptocurrencies will also fall within the collection requirements. Meanwhile, transfers to external wallets are explicitly included, extending the scope beyond activity conducted solely through conventional crypto trading.

The rules are scheduled to take effect in 2027, giving the industry a defined timeline to prepare ahead of implementation, including adjusting the data collection and record-keeping processes needed to capture the covered transaction types.

New Tax Compliance Obligations for Crypto Businesses

The legislation introduces additional responsibilities for cryptocurrency companies by making customer transaction data collection part of their tax-related compliance obligations. For exchanges and other covered crypto businesses, the specified transaction categories span different stages of digital asset ownership, ranging from acquiring and disposing of cryptocurrencies to exchanging tokens and moving assets into external wallets.

Because the requirements extend to routine activity such as token swaps and off-platform transfers, firms' data collection obligations will cover a wider share of customer activity than a framework limited to conventional purchases and sales. The inclusion of external wallet transfers is particularly relevant because cryptocurrency transactions are not limited to activity within a single trading platform. By explicitly including these transfers, the legislation identifies movements between platforms and to outside wallet addresses as part of the transaction information that crypto firms must collect.

Implementation Details Not Yet Specified

The announcement does not specify the precise information that companies must gather for each transaction, the reporting frequency, potential penalties for non-compliance, or the detailed implementation procedures. Those aspects cannot be established from the information provided by Coin Bureau.

Hong Kong's new requirement is set to begin in 2027. The legislation covers cryptocurrency purchases, sales, token swaps, and transfers to external wallets, placing these activities within the transaction data collection framework for tax purposes. As the 2027 start date approaches, the unspecified details around required data points, reporting procedures, and penalties will be key areas to watch for clarification.
