The bigger picture: what corporate tax avoidance actually costs, and where it came from

The rest of this site does the arithmetic on what large companies pay versus what you pay. This section steps back and asks the five questions the arithmetic raises but does not answer. What does the lost money actually amount to, in things a country buys? How did a tax system end up this way, and who built it? Is there a serious case for the defence, fairly stated? Who gets hurt the most? And after a decade of leaks, inquiries and reforms, did any of it work? None of these are rants. They are the context that turns a number into an understanding.

This is the part of LoopholeKiln that is not a calculator. The figures elsewhere on the site are pinned to primary sources and shown both ways; nothing here softens that discipline. But a figure on its own does not explain itself. US$347.6 billion a year is the corporate slice of global tax loss on 2021 data, and you can read it on our by the numbers page with its source attached. What that number means, how the rules that produce it were written a century ago, and whether the response since 2015 has dented it, are different questions. They are the ones this section answers.

What is in this section

• What it could fund takes each country's estimated annual corporate tax loss and translates it into one concrete public-service unit, the cost of a registered nurse, with both the loss figure and the salary primary-sourced and the whole thing labelled illustrative. It is not a budget proposal. It is a sense of scale.
• How we got here is the timeline: from the League of Nations economists who drew the first map of international tax in the 1920s, through the offshore boom, to the leaks of the 2010s, the OECD's BEPS project, and the global minimum tax now being switched on country by country.
• The counter-case states, as fairly and as strongly as we can, what multinationals and free-market economists argue in their own defence, and then weighs each argument against the evidence. The fairness is deliberate. A site that only quotes one side is a pamphlet, not a reference.
• Who suffers most is the part most coverage skips: the developing-world dimension. Lower-income countries lose a far larger share of their public budgets to this than rich ones do, and the section explains the mechanism and the development-finance argument, with India as the worked example.
• Did the crackdowns work is an honest scorecard of what enforcement actually recovered, what the whistleblowers risked and what happened to them, and where the response succeeded versus where it failed.

The thread running through all five

The same finding holds across every page below, and it is the finding of the whole site: the problem is the rules, not the people obeying them. A company that books profit in a low-tax jurisdiction within the law has done nothing a court would punish. The scale of what that costs, the history of how the rules came to permit it, the strongest arguments for leaving them alone, the countries that pay the steepest price, and the patchy record of attempts to change it, all point at the same place. Not the filer. The framework, and the governments that write it and decline to rewrite it.
