Hong Kong’s Crypto Tax Clock Starts Ticking in 2027 — CARF Spreads the Receipts

Hong Kong’s Legislative Council approved the Inland Revenue (Amendment) (Crypto-Asset Reporting Framework and Amended Common Reporting Standard) Bill 2026 on November 4, 2026, implementing the OECD’s Crypto Asset Reporting Framework (CARF) and the latest amendments to the Common Reporting Standard (CRS). Covered crypto service providers must begin collecting customer information from January 1, 2027.

The requirements cover crypto exchanges, brokers and other qualifying service providers, which must register with the Inland Revenue Department (IRD) from January 2027. Providers must collect customer names, addresses, tax residency, identification numbers and dates of birth, as well as report qualifying crypto purchases, sales, exchanges and transfers, including transfers to external wallets. Existing customers must provide tax residency declarations by January 2028, while new customers must supply the required information when opening an account.

Hong Kong will begin exchanging reported crypto information with participating jurisdictions in 2028 under CARF. The amended CRS takes effect in 2028 and expands coverage to digital financial products, with automatic information exchanges scheduled to begin in 2029. Hong Kong has exchanged financial account information under the CRS since 2018. Secretary for Financial Services and the Treasury Christopher Hui said the alignment would “reinforce the confidence of crypto-asset service providers,” while the IRD has established a dedicated team to assist the industry.

Other Asian jurisdictions are also tightening crypto reporting requirements. Singapore published its CARF regulations in August 2026, requiring new users to provide tax residency and identification numbers from January 1, 2027. Platforms cannot execute trades for users without valid self-certification from 2028. South Korea, Japan and Australia have committed to begin CARF exchanges by 2027, adding to regional scrutiny of crypto transactions and customer information.
