The Border Stopped Protecting Your Income

Six jurisdictions now tax residents on what they earn abroad and can see the ledger that proves it. What changed in China, Taiwan, Malaysia, Singapore, Indonesia and the US, and what a household should be able to reproduce on demand.

For a long time, "offshore" meant "out of sight". An account in another country was a private fact between you and a bank.

That is no longer true, and most households have not updated the model in their heads.

Two things changed at once. Residents are taxed on worldwide income in nearly every market on this list. And since the Common Reporting Standard (CRS) began, the bank abroad reports your balances and income to your home tax authority automatically. The question that matters is no longer where is it? It is can you reproduce it?

The tax authority increasingly holds the same ledger your bank does. Your job is to hold a better one.

What changed, jurisdiction by jurisdiction

As of 28 July 2026, this is what we could verify. Items we could only confirm through law-firm or press summaries are marked "reported", and every one has a source at the bottom.

Jurisdiction The rule to know Status
China Residents are taxed on worldwide income. Tax authorities have sent self-review notices on overseas income using CRS data. Reported rate on overseas dividends and gains: 20%. In force; enforcement waves reported in 2025 and 2026
China, offshore trusts Two announcements on 24 July 2026 treat a trust and the entities it controls as look-through for the resident who contributed, and treat the contribution itself as a disposal. A 90-day window to settle historical liabilities without late charges ends 22 October 2026. In force, applies to existing trusts
Taiwan Overseas income of NT$1 million or more per filing unit counts toward the Income Basic Tax. For 2026 the exemption stays at NT$7.5 million and the rate at 20%. Individual controlled-foreign-company rules have applied since 1 January 2023. In force
Malaysia Foreign-sourced income received by resident individuals is exempt until 31 December 2036, but only if it was already taxed abroad on income of a similar character. Gazetted (P.U.(A) 451/2024)
Singapore Singapore committed in November 2023 to implement the amended CRS and the new Crypto-Asset Reporting Framework from 1 January 2027. Crypto and e-money accounts come into scope. Committed; implementing rules to follow
Indonesia Residents are taxed on worldwide income. The finance minister said in May 2026 there will be no third tax amnesty while they hold the post. In force; amnesty not enacted
United States Citizens and green-card holders are taxed on worldwide income. Foreign accounts above US$10,000 in aggregate need an FBAR. Unchanged. In force

Three of these deserve a closer look.

China. The offshore trust rules are the sharpest change in the set. A trust that used to be a way to separate ownership from income is now treated, for a PRC-resident contributor, as transparent. Notably, the rules reach trusts that already exist. If you are in this position, the text of the two announcements and an adviser matter more than any summary, including this one. The deadline is close.

Taiwan. The mechanism is quieter and more durable. Income that stays inside a foreign company you control no longer waits for a dividend to be taxed, because the controlled-foreign-company rules can attribute it to you. The old advantage of an offshore holding company was deferral. The rule exists to remove exactly that.

Malaysia. The foreign-income exemption sounds generous, and it is, but the condition is the point. Income taxed abroad is exempt at home. Income that was not taxed abroad is not. A low-tax structure can quietly void the exemption you thought you had.

Why this is a record-keeping problem first

None of these rules ask you to know tax law. They ask you to produce facts. For every asset held abroad:

  • the cost basis and acquisition date
  • income by year, in the home currency, converted at a defensible rate
  • foreign tax paid, with the certificate
  • who controls it and who benefits, including any trust or company in between

A household that can generate this in an afternoon has a very different experience from one that has to reconstruct 2022 from emailed PDFs while an inquiry letter sits on the desk.

Three fundamentals that apply here

After-tax return is the only return. Portfolios are properly evaluated after tax, and the same asset earns different after-tax returns depending on where it is held. A structure that saves 1% a year in tax but triggers a deemed disposal at 20% on entry has to be judged on the whole path, not the annual saving.

Taxes and legal constraints belong in the Investment Policy Statement. The framework for an individual investor lists return and risk objectives, then constraints: liquidity, time horizon, taxes, legal and regulatory, and unique circumstances. "Legal and regulatory" is not an afterthought on this list. For a cross-border family it is often the binding one.

When two regimes apply, follow the stricter. Professional codes of conduct in the investment industry tell a practitioner who faces conflicting laws to comply with the stricter one. It is a good rule for households as well. If you are tax resident in Taiwan with an account in Singapore and a trust in the Cayman Islands, you are not choosing a regime. You are obeying all of them.

Practical implications

  1. Build the ledger now, while you can ask the bank for statements. Year-end balance, income, gains and cost basis per account, per year, for at least the last five years.
  2. Map every structure to a person. For each trust, foundation or company: who contributed, who controls, who benefits, and in which country each of them is tax resident.
  3. Check the conditions, not the headline. Malaysia's exemption has a condition. China's trust rules have a window. Taiwan's threshold is per filing unit, not per person.
  4. Plan for crypto being visible from 2027. In Singapore, crypto platforms become reporting entities. Past trades will be matched against what you declared.
  5. Treat deadlines as dated events. 22 October 2026 (China, trusts). 1 January 2027 (Singapore, CRS 2.0 and CARF).

Update, October 2026: what the following weeks added

Singapore. The Income Tax (Crypto-Asset Reporting Framework) Regulations 2026 were gazetted on 11 August 2026, and the tax authority issued the fifth edition of its CRS e-Tax guide the same day. The amended CRS and the new framework apply from 1 January 2027, with the first exchange of information in September 2028.

What we could not confirm

The body of this post reflects what was known on 28 July 2026; later developments are in the update section. We read the primary text of few of these rules. Several 2026 items rest on law-firm and press summaries, and some figures conflict between sources: for example, the dates of the Chinese tax authority's overseas-income notices, and whether tax on overseas gains is computed per transaction or net. The 20% rate and the 0.05% daily late charge in China are reported figures, not ones we verified against a primary page. This post is education, not tax advice. Check the rule that applies to you against the primary source or a qualified adviser.
