The Global Cost Of Tax Avoidance
Every year, the U.S. loses an estimated $189 in corporate tax, around 1.13 percent of GDP. China has the second highest annual losses in absolute terms with $66.8 billion while Japan is also badly effected with $47 billion unaccounted for. The IMF has reported that OECD countries lose approximately 2 to 3 percent of their total annual tax revenue while lower-income countries lose substiantially more. That trend can be seen by taking Chad as an example.
The paper estimated that the central African nation loses $950 million in tax revenue every year. Even though that might seem insignificant compared to other countries, those losses have a far-reaching impact equating to around 7 percent of Chad's GDP.
