Where money hides
Everyone pictures the same thing: a vault on a palm-fringed island, stacked with gold, guarded by a man in sunglasses. Forget it. Money does not hide by going anywhere, because money does not go anywhere: it is a number on a list. Money hides by having the name next to it changed, on a list kept somewhere that is not obliged to show anyone the list. That is the whole trick, and once you see it you cannot unsee it.
Money is not physically moved offshore. What moves is the ownership record. A company is registered somewhere that keeps ownership private, that company holds the asset, and the person behind it becomes very hard to identify. Britain sits at the centre of a network of such places, and campaigners who count this argue it is the largest such network in the world.
First, kill the vault picture
You have already learned on this site that the money in your bank account is not stored anywhere. It is a record: a line saying the bank owes you a number. Nearly all of the UK's money exists that way, as entries, not objects.
So when someone says money has been moved offshore, resist the film-set image. Almost nothing physically travels. A record is updated. And here is the thing about records: they are only as revealing as the rules that govern who has to publish them.
Hiding money, in practice, is not about distance. It is about which set of rules the record sits under.
The square mile that votes differently
Start close to home, with something so odd that most British adults do not know it and would not believe you.
In the middle of London there is a local authority called the City of London Corporation, covering roughly one square mile: the old financial district. Everywhere else in the United Kingdom, local elections work the way you would expect. People who live there vote. One person, one vote. That is the whole idea.
In the City of London, businesses vote too. Firms based in the square mile appoint voters, in numbers related to how many people they employ, and those business voters take part in electing the Corporation. When the current arrangement was set in law by the City of London (Ward Elections) Act 2002, the effect was that the business franchise came to vastly outnumber the residential one: roughly 32,500 businesses against about 6,000 resident electors.
The business vote existed across Britain once and was abolished everywhere else. In the square mile it was kept, and in 2002 it was expanded, by an Act of Parliament that anyone can read on the government's own legislation website.
This is not a secret. It is the opposite of a secret: it is written into statute, published, and almost entirely unremarked upon. Which is a useful lesson in itself. The most consequential arrangements are usually not hidden. They are just boring enough that nobody reads them.
The network around it
Now widen out. Britain is not only Britain. It has Crown Dependencies, such as Jersey, Guernsey and the Isle of Man, and Overseas Territories, such as the Cayman Islands, the British Virgin Islands and Bermuda. They are not foreign countries in the ordinary sense and they are not fully part of the UK either. They make many of their own laws, including the laws about what a company must disclose.
The Tax Justice Network, a campaigning research group that has counted this for years, calls the result the UK spider's web: the square mile at the centre, the territories arranged around it. On their Corporate Tax Haven Index of 2019, they concluded that this network was responsible for over a third of the world's corporate tax abuse risks.
That is their finding, from their index, using their method, and they are not a neutral party: they campaign for change. We are telling you whose number it is on purpose, because a number without an owner is not a receipt. Read their method, and read the governments that dispute it, and make up your own mind. What is not in dispute is the structure: the territories exist, their disclosure rules differ from Britain's, and the relationship with London is constitutional fact.
The instinct is to imagine criminals sneaking money out of the country. Usually it is the other way round. Somebody has built, quite openly, a service: we will register your company and we will not require the world to know who owns it. Lawyers, accountants and company formation agents sell that service, legally, for a fee.
Most of what flows through it is not criminal at all. It is ordinary corporate structuring, done by household-name businesses, entirely within the law. That is precisely what makes it hard to talk about without slipping into nonsense: the same plumbing serves the tax-efficient multinational and the person with something to hide, because the plumbing does not ask which one you are. It only asks whether you filed the form.
So the useful question is not "who is the criminal?" It is: who decided that this record should be private, and who benefits from it staying that way? That question has an answer, and the answer is a list of laws with dates on them.
What this does and does not prove
It does not prove that everyone using these places is a criminal, that all offshore activity is illegal, or that any particular named person has done anything wrong. Most of it is legal. That is the point, not a defence.
It does prove that a great deal of what people imagine to be secret conspiracy is instead published law, and that Britain is not a bystander in the global business of financial secrecy but sits at the middle of the largest network of it, according to the people who count these things.
- Read the City of London (Ward Elections) Act 2002 on legislation.gov.uk. It is not long. Business votes in a British local election, in the statute book, free to read.
- Look up any UK company on Companies House. It is free, it takes thirty seconds, and it lists directors and "persons with significant control". Then try to do the same for a company registered somewhere that does not publish that, and notice the difference. The difference is the story.
- Look up the list of British Overseas Territories and Crown Dependencies. Then look at which of them appear on international tax haven lists. Both lists are public.
- Read the Tax Justice Network's method, then read a government's rebuttal. Reading only one is how you end up certain and wrong.
The City of London (Ward Elections) Act 2002, on legislation.gov.uk, for the business franchise. The comparison of roughly 32,500 business voters to about 6,000 resident electors is widely reported in accounts of the Act; the Act itself is the document to start from.
The City of London Corporation's own website explains its elections and its structure in its own words. Worth reading precisely because it is not defensive: it does not consider any of this remarkable.
The Tax Justice Network's Corporate Tax Haven Index 2019, for the claim that the UK network is responsible for over a third of the world's corporate tax abuse risks. Their indexes and methodology are published in full. They are advocates; treat the figure as their argument, which you can check, not as a neutral fact.
Companies House, free, for what British disclosure actually looks like when it works.
Documentaries on this subject exist and are worth watching, including The Spider's Web: Britain's Second Empire. Like all documentaries they argue a case. Watch them for the shape of the story, then come back to the statutes and the indexes for the evidence. That order matters.
Questions people ask
Does money physically go offshore?
Almost never. Money is a record, not an object. What changes is who the record says owns the asset, and which country's disclosure rules that record sits under. The cash does not get on a plane.
Can businesses really vote in the City of London?
Yes. In elections to the City of London Corporation, firms in the square mile appoint voters in numbers related to their workforce. Under the arrangement set by the City of London (Ward Elections) Act 2002, business voters far outnumber the few thousand people who actually live there. It is the only place in the UK where this survives.
Is using an offshore company illegal?
Usually not. Much offshore structuring is entirely legal and done by ordinary large companies. Hiding money to evade tax or launder proceeds of crime is illegal. The same structures can serve both, which is exactly why the disclosure rules matter so much.
Is Britain a tax haven?
Britain itself has relatively strong company disclosure, including a free public register. The argument, made most loudly by the Tax Justice Network, is about the network: the Crown Dependencies and Overseas Territories, whose rules differ, with London as the financial hub. Governments dispute the framing. Both cases are public and worth reading.
What can anyone actually do about this?
Understand it first, which is what this page is for. Beyond that it is a question of law and politics, decided by people who are elected, which is one reason the City's unusual franchise is worth knowing about. This site does not campaign and does not tell you what to think. It shows you where the documents are.
