The system: the taxes you feel, the referees who are outgunned, and the people who write the rules

The rest of this site shows you the gap: a small firm pays a higher effective rate than a giant, and it is all legal. This section is about the machine that produces that gap. Not the clever structures, which we cover elsewhere, but the plumbing nobody campaigns about: the sales tax you collect and hand over, the tax authority being quietly cut while the avoidance industry hires, the official measures of what goes uncollected, and the committees in Paris, Brussels and New York that decide whose rules everyone follows. None of this is a scandal. It is arithmetic and organisation charts. That is what makes it worth reading.

Most coverage of corporate tax stops at the structures: the Double Irish, the royalty routed offshore, the profit booked in a country with no factory. We cover all of that in how they do it and the structures A to Z. This section is the part that gets left out, and it is the part a small business actually lives inside.

Four things, each with its own page, each covering ground the rate comparison does not.

• VAT and GST fraud. The tax a small firm feels most is not corporation tax. It is the sales tax you collect on every invoice and hand to the state. This page is about how that tax is stolen at scale, and how, for two decades, an overseas seller could legally undercut you by the exact percentage of the VAT you were obliged to charge.
• The asymmetry of arms. A tax authority on civil-service pay, cut year after year, against a professional advisory industry of roughly 1.5 million people earning multiples of the public wage. This page is about why avoidance wins structurally, before anyone gets clever.
• The tax gap. Every country measures what it fails to collect. This page takes each official estimate apart: how much is fraud, how much is honest error, how much is contested-but-legal, and how much of it sits with big companies versus small ones. The answer is not what most people assume.
• Who makes the rules. The OECD, the EU, the IMF and, newly, the United Nations. This page is about who actually writes international tax law, who has a vote and who only has a seat, and why the developing world spent 2023 voting to move the whole thing to a different building.

A note on what this section is not. It is not an accusation against any company. Stealing VAT is a crime and we say so; everything else here is the lawful operation of a system that governments designed and can change. Where we name a fraud, it is a matter of public record. Where we describe avoidance, it is legal. The line between the two runs through this whole section, and we keep it sharp.
