Tax Dodging by Super-Rich, Big Corporations Costs Nations Half a Trillion Per Year: Study

A study published Tuesday estimates that tax dodging enabled by the United States, the United Kingdom, and other wealthy nations is costing countries around the world nearly half a trillion dollars in revenue each year, underscoring the urgent need for global reforms to prevent rich individuals and large corporations from shirking their obligations.

The new study, conducted by the Tax Justice Network (TJN), finds that "the combined costs of cross-border tax abuse by multinational companies and by individuals with undeclared assets offshore stands at an estimated $492 billion." Of that total in lost revenue, corporate tax dodging is responsible for more than $347 billion, according to TJN's calculations.

"For people everywhere, the losses translate into foregone public services, and weakened states at greater risk of falling prey to political extremism," the study reads. "And in the same way, there is scope for all to benefit from moving tax rule-setting out of the OECD and into a globally inclusive and fully transparent process at the United Nations."

The analysis estimates that just eight countries—the U.S., Canada, the U.K., Japan, Israel, South Korea, Australia, and New Zealand—are enabling large-scale tax avoidance by opposing popular global reform efforts. Late last year, those same eight countries were the lonely opponents of the United Nations General Assembly's vote to set in motion the process of establishing a U.N. tax convention.

According to the new TJN study, those eight countries are responsible for roughly half of the $492 billion lost per year globally to tax avoidance by the rich and large multinational corporations, despite being home to just 8% of the world's population.

"The hurtful eight voted for a world where we all keep losing half a trillion a year to tax-cheating multinational corporations and the super-rich," Alex Cobham, chief executive of the Tax Justice Network, said in a statement Tuesday. "The U.K. and the U.S. are both among the biggest enablers and the biggest losers of this lose-lose tax system, and their people consistently demand an end to tax abuse, so it's absurd that the U.S. and U.K. are seeking to preserve it."

"It's perhaps harder to understand why the other handful of blockers, like Australia, Canada, and Japan, who don't play anything like such a damaging role, would be willing to go along with this," Cobham added.

TJN released its study as G20 nations—a group that includes most of the "hurtful eight"—issued a communiqué pledging to "engage cooperatively to ensure that ultra-high-net-worth individuals are effectively taxed." Brazil, which hosted the G20 summit, led the push for language calling for taxation of the global super-rich.

The document drew praise from advocacy groups including the Fight Inequality Alliance, which stressed the need to "transform the rhetoric on taxing the rich into global reality."

The communiqué was released amid concerns that the election of far-right billionaire Donald Trump in the U.S. could derail progress toward a global solution to pervasive and costly tax avoidance.

The new TJN study cites Trump's pledge to cut the statutory U.S. corporate tax rate from 21% to 15% and warns such a move would accelerate the global "race to the bottom" on corporate taxation.

"People in countries around the world are calling in large majorities on their governments to tax multinational corporations properly," Liz Nelson, TJN's director of advocacy and research, said Tuesday. "But governments continue to exercise a policy of appeasement on corporate tax."

"We now have data from these governments showing that when they asked multinational corporations to pay less tax, the corporations cheated even more," Nelson added. "It's time governments found the spines their people deserve from their leaders."
