What’s true in love isn’t necessarily true in international taxes. The whole point of a global system is so that national tax authorities can interact, whether through tax treaties or universal standards set by the Organization for Economic Cooperation and Development.
But this will be a crucial step for United States to stay in harmony with the OECD’s Pillar Two 15% global minimum tax, a top U.S. Treasury Department official said May 9.
“Our system is stable,” said Rebecca Burch, Treasury’s deputy assistant secretary for international tax affairs, during an American Bar Association tax conference in Washington, D.C. “It is my belief that the way to stabilize Pillar Two is to delink it from the U.S. system, to have a side-by-side system.”
From the first day of his presidency, Donald Trump has made clear through executive proclamations that the U.S. is no longer participating in the Pillar Two project—even though the U.S. was a major driver of it during the Biden Administration. Decrying the agreement as “discriminatory” and “extraterritorial,” Trump ordered Treasury to investigate retaliatory measures against countries which use Pillar Two laws to tax American companies. That would include the “income inclusion rule”—a top-down tax which countries would impose on their own corporate taxpayers if they have subsidiaries which pay below the 15% global minimum tax—or the “undertaxed profits rule,” the secondary rule which allows countries to tax the local subsidiaries of foreign multinational entities if they have any income that is taxed at less than 15% elsewhere in the world. Those rules, working in concert, would ensure that companies pay 15% on all income, no matter where it’s earned in the world.
The UTPR in particular has been a concern for Republican Pillar Two critics, who claim it will target U.S. companies, since the U.S. hasn’t enacted Pillar Two and has a minimum tax—the tax on global intangible low-taxed income—that is only applied at 10.5%.
But despite the early proclamation—and Republican legislation moving through Congress which would enact further retaliatory measures—Treasury officials have more recently indicated that they wouldn’t be opposed to “co-existing” with Pillar Two, so long as they reach an understanding of when it would apply. So far, it’s been a little murky what “coexistence” really means.
In language that wasn’t inflammatory—but was forceful, emphatic and unequivocal—Burch made clear: co-existence means no overlap between U.S. taxation and Pillar Two. Ever.
“The question is, does the U.S. tax the income or monitor the income?” Burch said. “If the answer is yes, there is no IIR. There is no UTPR.”
This means not only that U.S. companies shouldn't be taxed under Pillar Two, but that the income of foreign-parented multinational corporations that might be subject to U.S. tax should be kept out as well. And solutions which would only work most of the time—like extending a safe harbor which currently covers the U.S.—were “not enough,” Burch said.
“That does not create a side-by-side system,” she said. “And it does not respect the sovereignty of the United States.”
And, perhaps the biggest demand of all, Burch said that as Pillar Two shouldn’t apply to U.S. companies at all, they shouldn’t have to comply with its voluminous reporting requirements which non-U.S. companies are already fulfilling and which many tax officers have said will likely be costlier than the taxes themselves.
While much of the discussion about the U.S. and Pillar Two has focused on the differences between the two systems, Burch said this was the wrong prism to view the dynamic. The right question, she said, is whether U.S. anti-abuse rules like GILTI are “robust” enough to address base erosion and tax avoidance, the original goal of Pillar Two. Since they are, she contended, there’s no need for Pillar Two to apply.
That’s the “U.S. position,” Burch said, and she suggested it would be unwavering. No doubt many other countries will view it as high-handed and difficult to accommodate, and it may be that these differences will spark another round of retaliations and trade wars, on top of all of the others that Trump has triggered in his first few months in office.
But, given the administration’s often-antagonistic stance with global institutions, it wasn’t a given that the U.S. would participate in further OECD discussions at all. Another message that Burch highlighted during the ABA conference is that the U.S. was not walking away.
“We are here,” she said. “We are committed to a multilateral forum to solve this problem.”
