Hong Kong Crypto Tax Law Passed: Exchanges to Report From 2027

By Nodora News · 5 November 2026

Hong Kong passed a crypto tax reporting law on Nov 4, so exchanges must collect customer and trade data from 2027 and share it with foreign tax offices in 2028.

Hong Kong has passed a law that makes crypto exchanges and other crypto service providers collect detailed customer and transaction data for tax purposes. The Legislative Council approved the Inland Revenue (Amendment) (Crypto-Asset Reporting Framework and Amended Common Reporting Standard) Bill 2026 on Wednesday, November 4. From January 1, 2027, covered firms must start gathering the information, and from 2028 Hong Kong's Inland Revenue Department (IRD) will automatically share it with tax authorities overseas. The rules apply to activity in Bitcoin (BTC), Ether (ETH) and every other crypto asset handled by an in-scope provider.

Key takeaways

• Hong Kong's legislature passed its crypto tax reporting bill on November 4, 2026.
• Covered crypto firms must collect customer and transaction data from January 1, 2027.
• The first automatic sharing with foreign tax authorities is expected in 2028.
• Buys, sells, crypto-to-crypto swaps and transfers to outside wallets are all covered.
• A wider update to the bank-account reporting rules (CRS) follows on January 1, 2028.

What Hong Kong's new crypto tax law does

The law brings the OECD's Crypto-Asset Reporting Framework, known as CARF, into Hong Kong's tax code. The OECD (Organisation for Economic Co-operation and Development) designed CARF so governments can spot crypto gains that people fail to declare, especially when the money sits on an exchange in another country.

In practice, it works much like the system banks have used for years. A crypto service provider that falls within the rules has to identify which of its customers are tax residents of partner jurisdictions, collect their details, and file an annual report with the IRD. The IRD then passes the relevant records to the tax office in each customer's home country.

According to CoinDesk's reading of the rules, covered exchanges and brokers will need to record:

• Customer names and addresses
• Tax residency and tax identification numbers
• Purchases and sales of crypto for regular money
• Swaps of one token for another
• Transfers out to external wallets

The government says the data is shared only between tax authorities, on a reciprocal basis, and is not made public.

Key dates: 2027, 2028 and 2029

The bill and all the government's late amendments passed together, according to KPMG China, which expects the final ordinance to be published in the Government Gazette on November 13, 2026.

• January 1, 2027: CARF takes effect. The 2027 calendar year is the first reporting period.
• January 31 of the following year: the registration deadline for providers. Every covered provider has to register an account on the IRD's CARF portal, even if it has nothing to report.
• 2028: the first automatic exchange of crypto tax data with partner jurisdictions.
• January 1, 2028: the amended Common Reporting Standard (CRS) takes effect, widening the existing bank-account rules to cover more digital financial products.
• 2029: the first exchanges under the amended CRS.

Hong Kong has swapped financial account data with other tax authorities under the original CRS since 2018, so the machinery for this kind of sharing already exists. CARF extends it to crypto.

Why it matters for crypto exchanges and investors

Hong Kong has spent the past few years positioning itself as Asia's regulated crypto hub. It brought in licensing for crypto trading platforms in 2023, and it has been pushing tokenized finance and stablecoin trials through the Hong Kong Monetary Authority. You can read more about that push in our report on Hong Kong's 24/7 tokenized settlement plans.

Christopher Hui, the Secretary for Financial Services and the Treasury, framed the new law as part of that strategy. He said following the latest global tax transparency standards is key to Hong Kong's reputation as a financial centre and should give crypto firms and users more confidence to invest there long term.

For investors, the change is simple to state: crypto held on a covered Hong Kong platform will no longer be invisible to tax authorities back home. Someone who is tax resident in a partner country and trades on a Hong Kong exchange should expect that country's tax office to receive a yearly summary of their activity from 2028. KPMG advises crypto users to check whether their transactions will be reportable and what that means for their local tax bill.

For firms, the work starts now. KPMG says in-scope providers need to confirm whether they fall under Hong Kong's rules, review which of their products count as crypto assets, and make sure their systems can capture the required data before January 2027. The IRD has promised guidance and has set up a dedicated team to answer industry questions.

Hong Kong is not alone. Many other jurisdictions are rolling out CARF on similar timelines, and tax pressure on crypto is building elsewhere too, as seen in South Korea's debate over delaying its crypto income tax and France's vote on self-custody wallet reporting.

Market reaction: Bitcoin holds above $80,000

The law passed during a broad crypto rebound, and there was no visible market reaction to the news itself. Tax reporting rules of this kind had been expected for months, since the bill was first published in May 2026.

Prices on OKX at the time of writing:

• Bitcoin (BTC): about $80,520, up roughly 2.6% in 24 hours
• Ether (ETH): about $2,420, up roughly 4.0% in 24 hours

The wider market is still being driven by the US midterm results and the aftermath of the Binance hack rather than by tax rules. You can follow live prices on the Nodora charts page.

What to watch next

• November 13, 2026: expected publication of the final Amendment Ordinance in the Gazette.
• IRD guidance: practical details on how providers are identified and how the Hong Kong "nexus" tests (the links that put a firm in scope) apply.
• January 1, 2027: data collection starts for covered providers.
• 2028: the first crypto tax data leaves Hong Kong for partner jurisdictions.
