The Tax Justice Network claims that tax abuse costs the world $5 trillion. The claim is false.
The Tax Justice Network claims the world will lose $5 trillion in tax abuse over the next 10 years. They say $301bn of tax is lost each year to cross-border corporate tax abuse by multinationals, and £171bn is lost each year to tax evasion by wealthy individuals using tax havens.
Both claims are false. The corporate tax abuse calculation measures fictitious tax avoidance. The "tax haven" calculation has been falsified by actual cross-border tax reporting. TJN have used the same methodology for years, and ignored criticisms of it. Nobody should take these numbers seriously.
