Potentially the most significant change in global tax rules in 100 years, the accord is designed to stop countries from competing to lure corporations by offering lower tax rates and to help governments fund their operations at a time of soaring pandemic-related expenses. Biden administration officials also describe the tax plan as a partial remedy for the offshoring of manufacturing jobs that have hollowed out American factory towns and fueled populist resentments.

  The president called the deal an example of the “foreign policy for the middle class” that he had promised to deliver, though Republicans were quick to object, and numerous details remain for negotiators to resolve.

  Biden set for G-7 boost in bid for all nations to impose minimum global corporate tax

  “Multinational corporations will no longer be able to pit countries against one another in a bid to push tax rates down and protect their profits at the expense of public revenue,” Biden said. “They will no longer be able to avoid paying their fair share by hiding profits generated in the United States, or any other country, in lower-tax jurisdictions. This will level the playing field and make America more competitive.”

  The agreement announced Thursday also includes for the first time provisions for taxing the U.S. giants of the Internet economy, such as Google, Facebook and Amazon. In return, European countries that had instituted their own digital taxes are to remove them, though the OECD statement lacked a timetable for action.

  Treasury Secretary Janet L. Yellen called the agreement “a historic day for economic diplomacy” and said it represented one of the administration’s core foreign policy goals.

  “For decades, the United States has participated in a self-defeating international tax competition, lowering our corporate tax rates only to watch other nations lower theirs in response. The result was a global race to the bottom,” she wrote on Twitter.

  “Today’s agreement by 130 countries representing more than 90% of global GDP is a clear sign: the race to the bottom is one step closer to coming to an end,” she said in the tweet.

  The deal was notable for the inclusion of countries that had been skeptical, including China, Russia and India, tax experts said.

  Still, a great deal of work remains before a global minimum tax will become a reality. Participating countries must hammer out agreement on numerous details, bringing into alignment national tax systems that differ in important respects.

  “It is a very, very broad-brush document. Now we have to work to get the details,” said Catherine Schultz, vice president for tax and fiscal policy at the Business Roundtable.

  Every country will not be required to adopt the same 15 percent corporate tax rate. But if a country maintains a lower rate, the United States would be able to impose a compensatory levy on companies headquartered there, achieving the same objective.

  The agreement on taxing the profits of Internet companies even where they lack a traditional brick-and-mortar presence seems especially complex. The levy applies to multinational corporations with annual sales of more than 20 billion euros or roughly $24 billion and before-tax profit margins above 10 percent.

  “It requires an unprecedented degree of cooperation and coordination among countries, not just in the design of rules but in their application, permanently,” said Barbara Angus, global tax policy leader for Ernst & Young. “There’s a lot of work to be done.”

  A handful of countries did not sign on to the blueprint, including Ireland, a nation that has used its 12.5 percent corporate tax rate to attract U.S. technology and pharmaceutical companies over the past half-century. Likewise, Hungary and Estonia abstained, further complicating prospects for full European Union endorsement.

  Each of the 130 nations, including the United States, also must convert its endorsement of Thursday’s five-page plan into the nitty-gritty detail of legislation that will rewrite individual tax codes.

  The OECD statement said the two-pronged accord would reallocate the right to tax $100 billion in digital companies’ profits from their home nations to countries where they earn money even if they lack a physical presence there. The deal also sets a minimum corporate profits tax of “at least 15 percent,” which is expected to raise $150 billion annually, according to the OECD.

  The tax overhaul comes after several decades that saw policymakers lighten the tax burden on big business.

  Since 1980, the global average corporate tax rate, weighted by the size of each economy, has dropped from more than 46 percent to 26 percent, according to the nonprofit Tax Foundation. While good news for corporations and investors, the decline has made it harder for governments to fund popular benefits and other programs.

  President Donald Trump complained that other countries were using low tax rates to steal U.S. jobs, and Republicans in 2017 passed legislation reducing the corporate tax rate from 35 percent to 21 percent.

  Biden has proposed raising the rate to 28 percent to free individual taxpayers from more of the cost of expanding government programs. He also has proposed a 15 percent minimum corporate tax rate to prevent companies from using exemptions and deductions to effectively eliminate their tax liabilities.

  In the United States, annual revenue from corporate taxes relative to the size of the economy is now less than a quarter as large as in 1967, according to the Congressional Budget Office.

  The burden-sharing issue has grown only more acute as the coronavirus swept the globe. Governments worldwide spent a collective $16 trillion over the past year to fight the pandemic’s health and economic ills, according to the International Monetary Fund.

  “This historic package will ensure that large multinational companies pay their fair share of tax everywhere,” OECD Secretary General Mathias Cormann said. “This package does not eliminate tax competition, as it should not, but it does set multilaterally agreed limitations on it. It also accommodates the various interests across the negotiating table, including those of small economies and developing jurisdictions. It is in everyone’s interest that we reach a final agreement among all Inclusive Framework Members as scheduled later this year.”

  The global minimum tax is an essential element of the president’s plan to raise the corporate tax rate at home, by minimizing the incentive to move offshore to escape tax collectors. But early reaction from some prominent Republicans to the OECD statement was sharply negative.

  “This is a dangerous economic surrender that sends U.S. jobs overseas, undermines our economy and strips away our U.S. tax base,” said Rep. Kevin Brady (Tex.), the senior Republican on the tax-writing House Ways and Means Committee.

  Implementing the sweeping proposal would present its own challenges. Administering the new tax on digital companies would require “coordination between the IRS and other tax authorities on a day-to-day basis that we’ve never seen before,” said Angus, a former chief tax counsel for the Ways and Means panel.

  Negotiators aim to reach a final deal by the end of October, when the Group of 20 leaders are scheduled to meet in Rome, with implementation to start in 2023.
