Global Tax Deal Reached Among G7 Nations

LONDON — The top economic officials from the world’s advanced economies reached a breakthrough on Saturday in their yearslong efforts to overhaul international tax laws, unveiling a broad agreement that aims to stop large multinational companies from seeking out tax havens and force them to pay more of their income to governments.

Finance leaders from the Group of 7 countries agreed to back a new global minimum tax rate of at least 15 percent that companies would have to pay regardless of where they locate their headquarters.

The agreement would also impose an additional tax on some of the largest multinational companies, potentially forcing technology giants like Amazon, Facebook and Google as well as other big global businesses to pay taxes to countries based on where their goods or services are sold, regardless of whether they have a physical presence in that nation.

Officials described the pact as a historic agreement that could reshape global commerce and solidify public finances that have been eroded after more than a year of combating the coronavirus pandemic. The deal comes after several years of fraught negotiations and, if enacted, would reverse a race to the bottom on international tax rates. It would also put to rest a fight between the United States and Europe over how to tax big technology companies.

has been particularly eager to reach an agreement because a global minimum tax is closely tied to its plans to raise the corporate tax rate in the United States to 28 percent from 21 percent to help pay for the president’s infrastructure proposal.

EU Tax Observatory estimated that a 15 percent minimum tax would yield an additional 48 billion euros, or $58 billion, a year. The Biden administration projected in its budget last month that the new global minimum tax system could help bring in $500 billion in tax revenue over a decade to the United States.

The plan could face resistance from large corporations and the world’s biggest companies were absorbing the development on Saturday.

“We strongly support the work being done to update international tax rules,” said José Castañeda, a Google spokesman. “We hope countries continue to work together to ensure a balanced and durable agreement will be finalized soon.”

said this month that it was prepared to move forward with tariffs on about $2.1 billion worth of goods from Austria, Britain, India, Italy, Spain and Turkey in retaliation for their digital taxes. However, it is keeping them on hold while the tax negotiations unfold.

Finishing such a large agreement by the end of the year could be overly optimistic given the number of moving parts and countries involved.

“A detailed agreement on something of this complexity in a few months would just be lighting speed,” said Nathan Sheets, a former Treasury Department under secretary for international affairs in the Obama administration.

The biggest obstacle to getting a deal finished could come from the United States. The Biden administration must win approval from a narrowly divided Congress to make changes to the tax code and Republicans have shown resistance to Mr. Biden’s plans. American businesses will bear the brunt of the new taxes and Republican lawmakers have argued that the White House is ceding tax authority to foreign countries.
