- China's Ministry of Finance and State Taxation Administration imposed a 20% individual income tax on money moved into, earned inside, and paid out of offshore trusts, retroactive to 1 January 2023 (Announcement No. 21 of 2026, 24 July 2026).
- A 90-day penalty-free filing window ran from the announcement to 22 October 2026. The tax authority's own reminder, posted three days before the deadline, restated that date with no extension.
- Haidilao co-founder Shu Ping's family trust sold 259 million shares, about $351 million, in September to raise cash before the deadline. Bloomberg estimates eight Chinese billionaires hold roughly $140 billion through offshore trust structures now inside the rule.
- This resolves an open marker from our July reading of the US Treasury market: a government rewriting who can hold wealth where, and on what terms, is not something only Washington is doing in 2026.
On 22 October 2026, a 90-day amnesty on a new Chinese tax ran out, and by then some of the money it targeted had already moved. Haidilao co-founder Shu Ping's family trust had sold 259 million shares of the hotpot chain in September, raising about $351 million. Bloomberg's own tally puts eight Chinese billionaires' exposure to offshore trust structures at roughly $140 billion as of 16 October.
This closes a marker we flagged in September when writing about who still buys US Treasuries: China had introduced a 20% tax on offshore trusts in July, with a transitional window ending 22 October and retroactive cover running back to 2023. We did not recheck it at the time. Here is what actually happened.
A three-year catch-up, then a deadline
China's Ministry of Finance and State Taxation Administration jointly issued Announcement No. 21 of 2026 on 24 July, titled plainly as covering "individual income tax matters concerning offshore trusts." The rule reaches a trust at three points. Moving property into an offshore trust is taxed as property-transfer income, on the gain over the asset's original cost. Every year the trust exists, its income is taxed to the resident individual at 20%, as property-transfer or as interest, dividend and bonus income, whether or not the money is actually paid out. Winding the trust up taxes whatever potential gain remains. A companion rule, STA Announcement No. 15, issued the same day, sets out the forms: an annual self-declaration (Form B), an Offshore Trust Details Table, an Offshore Trust Annual Reporting Form, and a five-year instalment option for anyone who registers for it before filing.
The retroactive date is 1 January 2023, which by 22 October gave the rule close to three years of back tax to collect in one pass. The announcement also closes an obvious workaround: if a resident individual actually supplies, bears the cost of, or controls property nominally funded by someone else, the trust counts as that individual's own for tax purposes, and undistributed income sitting inside entities the trust controls is pulled into the tax base rather than left alone until distribution.
What softened the arrival was a 90-day window, running from the 24 July effective date to 22 October, in which filing and paying 2023-2025 liabilities drew no late-payment surcharge. The State Taxation Administration posted its own reminder on 19 October, three days before the deadline, telling taxpayers to review their offshore trust position and file within the transition period or face surcharges and other risk afterward. It restated 22 October. No extension followed.
The selling started before the deadline
Shu Ping is one of Haidilao's two founders, alongside her husband Zhang Yong. Their stakes sit in two BVI vehicles, ZY NP Ltd and SP NP Ltd, themselves held through discretionary trusts, Apple Trust and Rose Trust. On 8 September, SP NP Ltd sold 259 million Haidilao shares at an average HK$10.62, about HK$2.75 billion, cutting its stake from 700.61 million shares (12.57% of the company) to 441.61 million (7.92%). The company's own filing to the Hong Kong exchange, disclosed 9 September, gave the reason as the trust's own funding needs. It was the first large, publicly documented sale tied to the new tax, more than five weeks before the window closed, and Caixin reported it under the headline that the trust had sold a "$351 million stake."
Sale disclosed as driven by the trust's own funding needs, five weeks before the amnesty expired.
A rough day in Hong Kong, with an asterisk
The Hang Seng Index closed down 3.03% on 22 October, at 22,934.68. The Hang Seng Tech Index fell harder, 5.03%, to 3,793.93, a two-year low, with names including Alibaba and Tencent among the decliners. The date is the same one the trust amnesty expired on, and more than one outlet noted the coincidence.
It is worth being exact about what is and is not established here. Caixin Global's own reporting on the deadline treats a causal link between the tax deadline and the index move as unconfirmed, not as fact. Chinese AI and technology names had a difficult week on other grounds too. A forced-seller deadline and a market selloff landing on the same day is a fact. Which one caused which, if either did, is not.
Where this sits
This is not an isolated tax grab, read against what else has happened to capital this year. Indonesia cut its documentation-free monthly FX purchase threshold from $100,000 to $10,000 between April and July. The European Commission told five Caribbean states in June to wind down citizenship-by-investment programmes that sell visa-free EU-adjacent access, with a 2028 phase-out deadline. France's finance committee tried twice in nine months to tax investment securities held inside family holding companies. None of those episodes used the word capital controls. Each one changed a rule about where money has to sit, who has to hold what, or on what terms it may leave, and left the people affected to do the adjusting.
China's version has a cleaner mechanism than most: a rate, a retroactive date, a 90-day deadline, and a named reminder three days out. What it shares with the others is the shape. Nobody announced that offshore wealth would be harder to hold. A tax authority set a date, and by the time it arrived, at least one of the country's best-known family fortunes had already sold stock to meet it.
What we are watching
Whether the State Taxation Administration publishes any aggregate figure for how much was declared or collected during the window; none has surfaced as of 23 October. Whether further large, trust-linked share sales follow in Chinese and Hong Kong-listed names over the next two quarters, the way Shu Ping's did ahead of the deadline rather than after it. And whether the next release of US Treasury International Capital data, due 18 November 2026 for September holdings, shows any shift in Chinese-held foreign assets large enough to separate from the usual monthly noise.
Our take
Take the sceptical case first. Tax amnesties with enforcement teeth are not new in China, and a single 90-day window closing on schedule is not proof of a durable shift in how Beijing treats capital held abroad. The retroactive reach to 2023 could also be read as a one-time catch-up after a known policy gap, settled now so the rule can run cleanly from 2026 onward, rather than the opening move of something larger. And the Hang Seng's 22 October drop has other candidates behind it: a rough week for Chinese AI and tech names generally, not only trust-driven selling.
Our reading is narrower, and it is the same one this storyline has been tracking since the US side of it in September. A government under pressure to find revenue or control capital rarely announces a change of terms outright. It changes the rule about where money has to sit, who has to hold what, and on what terms it may leave, then lets taxpayers do the rest of the work. Indonesia cut its documentation-free FX purchase limit from $100,000 to $10,000 over four months this year. The EU told five Caribbean states to close citizenship-by-investment programmes by 2028. France tried, twice, to tax passive wealth inside family holding companies. China has now done the same thing to money its own residents moved offshore through trusts, with a mechanism, a deadline and a 20% rate attached rather than a speech.
For anyone tracking Chinese equities or advising capital that touches Hong Kong-listed names, the practical point is narrower still: a forced-seller event with a known deadline is a different kind of risk than ordinary volatility, and it is worth knowing which large holders are structured through offshore trusts before the next deadline like this one arrives, not after.
We hold assets across several jurisdictions as a matter of general practice. We have no position in, and this piece makes no comment on, any individual stock named here. Treat the above as a disclosed general interest, not a recommendation.
Common questions
What is China's new offshore trust tax?
China's Ministry of Finance and State Taxation Administration issued Announcement No. 21 of 2026 on 24 July 2026, imposing a 20% individual income tax on resident individuals' offshore trusts at three points: when property is transferred into the trust (taxed on the gain over its original cost), every year the trust holds income whether or not it is paid out, and when the trust is wound up. A companion filing rule, STA Announcement No. 15, sets out the forms and a five-year instalment option for anyone who cannot pay at once.
When did the window to declare offshore trusts without penalty end?
The announcement carried a 90-day transitional period from its effective date, running from 24 July to 22 October 2026. Filing and paying within that window waived the late-payment surcharge on 2023-2025 liabilities. The State Taxation Administration posted a reminder on 19 October restating the 22 October date, and no extension has been announced since.
How far back does China's offshore trust tax reach?
Transfers into an offshore trust and the trust's income are taxable from 1 January 2023, close to three years of retroactive exposure by the time the amnesty closed. A trust funded through another person or entity is treated as the resident individual's own trust if that individual actually supplied, bore the cost of, or controlled the property, which closes the layering route some structures relied on.
Which Chinese billionaires are affected by the offshore trust tax?
Bloomberg identified eight Chinese billionaires holding an estimated $140.2 billion in shares through offshore trust structures as of 16 October 2026, including NetEase's Ding Lei at roughly $37 billion and PDD's Huang Zheng at roughly $29 billion. That is Bloomberg's own compiled estimate, not a government figure, and it covers only the holdings its reporting could identify.
Did the tax deadline cause the Hong Kong market selloff on 22 October 2026?
The Hang Seng Index fell 3.03% to 22,934.68 that day and the Hang Seng Tech Index fell 5.03% to a two-year low. The timing coincides with the deadline, but financial press covering the move, including Caixin Global, has called a direct causal link speculative and unconfirmed. Plenty else was happening in Hong Kong tech names that week.
What happens to someone who missed the 22 October deadline?
The amnesty against late-payment surcharges ends. The underlying liability does not go away: it is collected under China's ordinary Tax Collection and Administration Law, with surcharges accruing and the case handled as enforcement rather than voluntary disclosure. A five-year instalment plan was only available to those who registered for it before the deadline.
