China seeks 25-year back taxes

China’s new offshore-trust tax rules are being read alongside a broader enforcement push that reaches far beyond fresh filings. The immediate legal change is clear: the Ministry of Finance and the State Taxation Administration issued new rules on July 24 requiring Chinese resident individuals to declare and pay individual income tax on offshore-trust income. What has drawn the most attention is the lookback. Reports this week said tax authorities are also pursuing unpaid tax on offshore wealth going back as far as 25 years, pulling old capital transfers and trust income into view. ### What exactly changed on July 24? China’s Ministry of Finance and State Taxation Administration issued Announcement No. 21 of 2026 on July 24, while the tax agency separately issued Announcement No. 15 of 2026, both effective immediately. The rules clarify how individual income tax applies when Chinese residents place assets into offshore trusts, during the life of those trusts, and when assets or income are distributed. (english.scio.gov.cn) The official framework says Chinese resident individuals must declare and pay tax on income derived from transferring assets into offshore trusts and on income generated during the trusts’ lifetime. KPMG said the measures were designed to clarify tax responsibilities across the entire lifecycle of offshore trusts and strengthen administration of individual income tax.

Asia Times reported on August 5 that Chinese authorities are chasing decades of unpaid tax on offshore wealth and, in some cases, reaching back as far as 25 years. That implies some reviews could reach to about 2000, well before the July 24 rule change, although the article framed the sweep as enforcement tied to wealth that had already been moved offshore. (english.scio.gov.cn) A tax notice carried by a provincial China tax bureau says that for offshore trusts generating income before January 1, 2026, resident individuals must declare and pay tax within 90 days from the announcement’s implementation date, without late-payment surcharges in specified cases. That official language does not itself use the phrase “25 years,” but it does confirm a backward-looking settlement window for pre-2026 income. (asiatimes.com) ### Who is most exposed? Wealthy Chinese families, expatriates with offshore structures, and advisers handling trusts appear to be the most directly affected. CNBC reported on August 5 that Beijing’s move had triggered a rush to lawyers and a scramble for cash among wealthy Chinese clients using offshore trusts to hold assets including pre-IPO stakes and family fortunes. (guangdong.chinatax.gov.cn) Professional advisers have described the rules as significant because they combine substantive tax treatment with a filing and enforcement framework. Dentons Rodyk said the July 24 announcements together set out both the tax rules and the administration mechanism for China-linked offshore wealth structures. ### Why is this surfacing now? (cnbc.com) China’s property market remained under pressure on August 5, with China Economic Review saying Beijing had shown little sign of providing major new support even after the latest Politburo signals on stabilizing housing. The same day, The Epoch Times reported that factory owners in Zhejiang and Jiangsu were facing falling orders, delayed payments, price wars and increased tax inspections. (dentons.rodyk.com) Those reports do not prove motive, but they place the tax drive against a backdrop of broader economic strain. Asia Times linked the offshore-tax sweep to a state effort to reclaim revenue from wealth that had left the country, while separate reporting on property and manufacturing showed pressure on other parts of the economy. ### What happens next for taxpayers? (chinaeconomicreview.com) The clearest near-term milestone is the 90-day filing window set by the July 24 rules. Counting 90 days from July 24 puts the deadline at October 22, 2026, for declarations tied to pre-2026 offshore-trust income under the transition arrangement. Between now and October 22, Chinese resident individuals with offshore trusts, along with their lawyers, tax advisers and trustees, will be working through disclosures, valuations and payment calculations under Announcement No. 21 and State Taxation Administration Announcement No. 15.
