Hong Kong Passes Crypto Tax Reporting Law, Adopting OECD Framework From 2027

Published November 4, 2026, 7:50 PM PKT. Based on the Hong Kong Government press release welcoming passage of the bill, issued November 4, 2026 at 5:50 PM Hong Kong time (primary source), crypto.news' November 4, 2026 report (secondary source), and Crypto Briefing's November 4, 2026 report (secondary source).

Hong Kong's Legislative Council passed a crypto tax reporting law on November 4, 2026, adopting the Organisation for Economic Co-operation and Development's Crypto-Asset Reporting Framework, known as CARF, in a move that will make crypto transactions visible to tax authorities across partner jurisdictions within two years. The Government welcomed passage of the Inland Revenue (Amendment) (Crypto-Asset Reporting Framework and Amended Common Reporting Standard) Bill 2026 the same day, according to its press release, issued at 5:50 PM Hong Kong time. The law does not create a new tax on crypto assets. It creates a reporting pipeline: from 2027, covered crypto businesses must collect customer and transaction information, and from 2028 the Inland Revenue Department will exchange that information automatically with partner jurisdictions every year. The bill also updates the existing Common Reporting Standard, which governs exchange of financial account information between tax authorities, with the amended standard taking effect in 2028 and its first exchanges scheduled for 2029.

What exchanges must collect from January 1, 2027

The obligations fall on businesses classed as reporting crypto-asset service providers, and the list is broad. According to crypto.news, CARF applies to businesses that facilitate cryptocurrency transactions for customers, including exchanges, brokers, dealers and certain operators of crypto ATMs, and companies with a reporting connection to Hong Kong will be subject to registration, customer due diligence, recordkeeping and reporting obligations. Crypto Briefing reported that data collection obligations kick in on January 1, 2027, and that affected providers must register with the Inland Revenue Department from that date regardless of their activity level. The reporting requirements cover transactions involving exchanges between cryptocurrencies and fiat currencies, trades between different crypto assets, and certain transfers involving external wallets, crypto.news reported. Service providers must collect identifying information about reportable customers, including their tax residence and taxpayer identification numbers, alongside the relevant transaction details. The framework covers both fungible and non-fungible crypto assets that can be used for payments or investments, while central bank digital currencies, specified electronic money products and certain assets that cannot be used for payments or investments are excluded, according to crypto.news. The legislation follows a consultation held between December 2025 and February 2026, during which the government sought feedback from financial institutions, professional bodies and cryptocurrency businesses, and the proposed legislation was published in May before being introduced to lawmakers in June, crypto.news reported. Crypto Briefing added that the bill was gazetted on May 22, 2026.

The 2028 first exchange and the 2029 CRS clock

The Government's press release sets out the timetable in full. CARF will be implemented in Hong Kong next year, when relevant service providers will be required to collect the information specified under the framework, allowing the Inland Revenue Department to exchange this information with partner jurisdictions starting from 2028. The amended Common Reporting Standard will also take effect in 2028, and the department will automatically exchange financial account information with suitable partners in accordance with the new standard starting from 2029. Hong Kong will conduct exchanges on a reciprocal basis and on the premise of data confidentiality and security, the release said. Secretary for Financial Services and the Treasury Christopher Hui tied the law to the city's standing as a financial centre, saying: "Implementing the latest international standards for automatic exchange of information in tax matters is crucial to maintaining Hong Kong's reputation as an international financial and commercial centre." He added that alignment with the latest 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, according to the release. To help the industry adapt, the Inland Revenue Department will issue relevant guidance and has set up a dedicated team to provide technical support and address enquiries, the release said. The machinery is not new: since 2018, Hong Kong has conducted automatic exchanges of financial account information with partner jurisdictions annually under the Common Reporting Standard, helping tax authorities detect and combat tax evasion, according to the release. The amended standard expands that framework to cover certain digital financial products, including central bank digital currencies, specified electronic money products and financial instruments linked to cryptocurrencies, crypto.news reported, and includes provisions intended to prevent duplicate reporting where transactions fall under both CARF and the updated standard. The law lands alongside a wider Hong Kong digital asset push: in October, the government outlined plans for licensing across four additional virtual asset services, covering dealing, custody, advisory and asset management activities, and the September policy address set out plans to expand regulated stablecoin trading and tokenized real world assets, crypto.news reported.

The 14 percent coverage question

The honest limit of the new law is what it cannot see. CARF reaches regulated service providers, not the whole crypto economy, and crypto.news cited blockchain analytics firm Chainalysis as estimating that potentially taxable onchain cryptocurrency activity exceeded $457 billion globally in 2025, with transactions within the practical reach of CARF representing approximately 14 percent of that activity. The remaining 86 percent included decentralized exchange transactions, peer to peer transfers, onchain income and cryptocurrency payments that fell outside the framework's practical reporting coverage, according to the firm's analysis as reported by crypto.news. The OECD originally published CARF in 2023 to establish a common system through which participating jurisdictions could exchange information about cryptocurrency transactions involving their tax residents, and Hong Kong's passage puts it among the jurisdictions turning that standard into domestic law with a fixed start date. For Hong Kong crypto businesses, the practical consequence is a compliance deadline, not a tax bill: registration and data collection systems must be ready by January 1, 2027, with the first cross border data flows following in 2028. For users, the consequence is narrower privacy: transactions routed through a Hong Kong reporting provider will be collected, checked against tax residence, and shared annually with the tax authority of that residence.
