The United States is pushing in the G20 to adopt a global minimum corporate tax to stem the erosion of government revenues, US Treasury Secretary Janet Yellen said Monday.
Just days after President Joe Biden announced plans to raise corporate taxes to finance a massive $2 trillion infrastructure and jobs program, Yellen said a collective international effort would end the "race to the bottom" on taxation.
Biden expressed outrage at multinationals -- like Amazon -- that have moved to tax havens or used loopholes and pay little to no tax, far less than some individuals, and said he would put a stop to the practice.
His plan would raise the US corporate tax rate to 28 percent and the minimum for multinationals to 21 percent.
He dismissed concerns the higher rate would drive companies overseas, telling reporters on Monday that "there's no evidence of that."
"We're talking about a 28 percent tax that everybody thought was fair enough for everybody," he said.
"I'm going to push as hard as I can (to) change the circumstances so we can compete with the rest of the world."
Yellen said the practice of seeking tax havens erodes government revenues and undermines an economy's competitiveness.
"Together we can use a global minimum tax to make sure the global economy thrives based on a more level playing field in the taxation of multinational corporations," she said in a prepared speech to The Chicago Council on Global Affairs.
The interconnected global economy has led to "a 30-year race to the bottom on corporate tax rates."
But for companies and economies to remain competitive, governments must make sure they "have stable tax systems that raise sufficient revenue to invest in essential public goods and respond to crises, and that all citizens fairly share the burden of financing government."
Biden's proposal recognizes "it is important to work with other countries to end the pressures of tax competition and corporate tax base erosion," Yellen said.
A Treasury official told reporters the G20 goal is to have a proposal on the global minimum tax by July, and the Biden administration could if needed change its legislation to bring the US minimum tax into line with the international plan.
Not going it alone
Yellen's speech, ahead of the spring meetings of the International Monetary Fund and World Bank, as well as a meeting of G20 finance ministers, all virtual, also outlined the Biden administration push to resume the multilateral cooperation halted under former president Donald Trump.
"Over the last four years, we have seen firsthand what happens when America steps back from the global stage. America first must never mean America alone," Yellen said.
In fact a strong US presence is necessary to ensure a level playing field in the global economy she said.
"Over time, a lack of global leadership and engagement makes our institutions and economy vulnerable."
The Biden administration already announced it is rejoining the Paris climate accords, and removed obstacles in the World Trade Organization that allowed the global body to name a new leader.
In the trade arena, she said Washington will work with partners to "enforce a rules-based order."
With China -- the world's other dominant economy -- the relationship "will be competitive where it should be, collaborative where it can be, and adversarial where it must be."
