The Biggest Tax Haven on Earth Is Not Switzerland

In 2010, the United States passed a law that ended banking secrecy.

It was called FATCA, and its logic was blunt. Any foreign bank that wanted access to the American financial system had to report its American account holders to the IRS. Refuse, and a punitive withholding tax would be applied to your dollar transactions. For a bank, that is not a fine. That is a death sentence.

The world folded. Switzerland, whose banking secrecy law dated to 1934 and had survived a world war, capitulated. Swiss banks handed over account holder names, paid billions in penalties, and closed accounts for American clients en masse. The Cayman Islands signed. Luxembourg signed. Over one hundred jurisdictions eventually adopted the global standard for automatic exchange of financial information.

It was, by any measure, one of the most successful acts of financial coercion in modern history. The era of hidden offshore accounts was declared over.

Then something happened that almost nobody outside the industry noticed.

The United States did not join.

Here is the full file.

To understand what happened, you need to see the difference between two systems that sound identical.

The rest of the world uses the Common Reporting Standard. Over one hundred countries participate. Each one collects information on foreign account holders and automatically sends it to their home tax authority. France tells Germany about German money in French banks. Germany tells Italy. Everyone tells everyone. It is a genuine multilateral network of transparency.

The United States uses FATCA. It never joined the CRS.

FATCA looks the same from a distance. It is an information exchange agreement. But look at what actually flows in each direction. The Congressional Research Service, the non-partisan research arm of the US Congress, examined the arrangement and concluded that the United States receives far more information on American owners of foreign accounts than other countries receive on foreign owners of American accounts.

The imbalance is not subtle. Under the agreements, the US receives nearly everything: balances, income, beneficial owners, the full picture. What it sends back is the account holder's name, address, tax ID, account number, and the bank's name. Crucially, it does not send the beneficial owners of accounts held by entities.

That last clause is the entire game. If a foreign national holds money in America through a company or a trust, the country he lives in never learns his name.

The Congressional Research Service put it in the plainest language a government body ever uses about its own country. The failure of the United States to share information under FATCA, it wrote, makes it one of the major secrecy jurisdictions in the world.

Legislation would be required to fix it. That legislation has been proposed. It has not passed.

The result was a one-way valve. America forced open every vault on earth and left its own door locked. And money, which has no patriotism and excellent lawyers, went exactly where you would expect.

To see where it went, you have to go to a place that appears in no thriller about offshore finance.

South Dakota has roughly 900,000 people and considerably more cattle. It has no income tax, no inheritance tax, and no capital gains tax. Its largest city, Sioux Falls, has fewer residents than a mid-sized European suburb.

It is also, according to the Pandora Papers investigation, one of the most significant tax havens on earth.

The story begins in 1983 with a legal doctrine most people have never heard of and which was, until then, one of the load-bearing walls of the Western legal system.

The rule against perpetuities dates to eighteenth-century English common law. It said that a trust must eventually die. Roughly a century after it was created, the trust had to be liquidated, and the wealth inside it exposed once again to capital gains tax, estate tax, and whatever else the jurisdiction imposed.

The rule existed for one reason, and the framers of it stated it openly. It was designed to check dynastic power. To restrict, in the phrase the lawyers used for three centuries, the power of the dead over the living.

In 1983, the governor of South Dakota persuaded the state legislature to repeal it.

There is now no time limit. A trust created in South Dakota can run forever.

And that single change created something that had not existed in the English-speaking world since before the American Revolution: a legal vehicle in which family wealth can compound, across generations, without end, never passing through an estate at death, never triggering the tax that is supposed to fire when wealth moves from one generation to the next.

The industry calls it a dynasty trust. The name is accurate.

The mechanism sounds abstract until you run the arithmetic, and then it becomes the most concrete thing in this newsletter.

The South Dakota Trust Company itself publishes the example. Take five million dollars. Place it in a dynasty trust for 120 years. Grow it at a conservative six percent per year.

At the end, it is worth 5.4 billion dollars.

Now take the same five million, given as an ordinary gift, subject to the ordinary taxes that fire at each generational transfer. After the same 120 years, it is worth 340 million.

Same money. Same growth rate. Same century.

The difference between the two numbers, roughly five billion dollars, is the tax that never fired. It is not evaded. It is not hidden. It is structurally avoided by an instrument that a state legislature legalized in 1983 and that any sufficiently advised family can use.

This is why the assets came. South Dakota's trust assets more than quadrupled over the past decade to roughly 360 billion dollars. The Guardian put the figure at 367 billion. The Pandora Papers named 81 trusts in the state alone.

The families whose wealth sits in these structures include names you know from hotels, from chewing gum, from American industry. And, increasingly, names from very far away.

Here is where the two halves of this story meet, and the picture that emerges is not flattering.

The Pandora Papers, a leak of nearly 12 million financial records, found South Dakota had become a major destination for foreign assets. Not American family money alone. Foreign money, arriving from jurisdictions that had just been forced open by American pressure.

The reporting documented trusts in the state connected to a Colombian textile magnate caught in a scheme to launder the proceeds of an international drug ring. To an orange juice magnate who settled with Brazilian authorities over allegations of colluding to underpay local farmers. To relatives of the former president of a Dominican sugar producer facing allegations about labor conditions.

The state's privacy law is the most thorough in the United States for trust matters that reach a court: an automatic and total seal, in perpetuity.

Note the sequence carefully, because it is the whole story in three steps.

America forced the world's secrecy jurisdictions open. Money left those jurisdictions because they were no longer safe. It arrived in a jurisdiction that had spent thirty years building the legal architecture to receive it, and which does not report beneficial owners back to the countries that money came from.

South Dakota is not alone. In Delaware, the vehicle is the anonymous limited liability company. Delaware has more registered corporations than people, and roughly two thirds of the Fortune 500 are incorporated there. When the Tax Justice Network first ranked financial secrecy jurisdictions by both opacity and scale, Delaware came first. Ahead of Luxembourg. Ahead of Switzerland. Ahead of the Cayman Islands.

Nevada and Wyoming run similar operations. Florida specializes in the all-cash property purchase. Each state has its instrument.

The United States now sits second on the Tax Justice Network's global Financial Secrecy Index, behind only Switzerland.

The country that ended offshore banking secrecy is, by the measure of the organization that invented the index, the second largest provider of financial secrecy on earth.

There is one detail in the South Dakota story that tells you more than any number in it.

The governor who repealed the rule against perpetuities did not stop there. Once other states began following, he created what was called a trust task force to keep South Dakota ahead of the competition.

Year after year, according to the Pandora Papers reporting, state lawmakers approved legislation drafted by trust industry insiders, providing successively more protection and more benefit for trust customers in America and abroad.

Read that mechanism again. The industry writes the bill. The legislature passes it. The industry writes the next one.

There is no corruption in this story, in the sense of envelopes and bribes. There is something more durable. A small state discovered that it could sell one thing the rest of the world could not: legal permanence. It priced the product, and it let the customers design it.

Delaware, Alaska, Nevada, and a dozen others followed for the same reason. This is regulatory competition, the same dynamic that built the Cayman Islands, running between the states of the country that spent a decade lecturing the Cayman Islands.

The instinct here is outrage. Resist it, because outrage produces nothing. There are three things to take away instead.

A tax haven is not a place. It is a legal condition. Everyone pictures a palm tree and a numbered account. The actual product is much simpler: a jurisdiction that will not tell your home country your name, and that will let a structure hold assets indefinitely. Those two features can exist in the Caribbean, in the Alps, or on the Great Plains. Stop asking which countries are tax havens. Start asking which jurisdictions offer permanence and non-disclosure, because that list changes, and the money moves to it long before the public reads about it.

Enforcement moves the money. It does not remove it. FATCA was genuinely effective. It ended Swiss secrecy for Americans and it recovered real revenue. And its second effect, entirely predictable and almost entirely unreported, was to redirect the world's mobile wealth into the one large jurisdiction that had exempted itself. Every future crackdown will do the same thing. Money is liquid and law is territorial, and as long as that asymmetry exists, enforcement in one place is a marketing campaign for somewhere else. When you read about the next great transparency initiative, the useful question is not whether it will work. It is where the money will go when it does.

The vehicle scales down. This is the part that matters for you, and it is why this newsletter is not just a story about billionaires. A dynasty trust is an extreme version of an ordinary principle: assets held inside a structure behave differently from assets held in your own name. The structure separates control from ownership. It survives its creator. It does not trigger the events that fire when things move between individuals. You do not need 5 million dollars or a South Dakota address to use a version of this. Trusts, holding companies, and tax-deferred accounts exist in retail form in nearly every developed country, and each is the same move performed at human scale. The difference between the family that compounds for a century and the family that starts over every generation is not the size of the first fortune. It is whether anyone in that family ever learned that structures exist.

$5,400,000,000. What 5 million dollars becomes after 120 years inside a South Dakota dynasty trust, at a conservative 6 percent.

$340,000,000. What the same 5 million becomes over the same 120 years, given as an ordinary gift and taxed the ordinary way.

The gap is roughly 5 billion dollars, and it is not made of investment returns. It is made of a single sentence that a state legislature repealed in 1983, in a state with more cattle than people, four decades before anyone told you it had happened.

That is not a conspiracy theory. That is the trust company's own brochure.
