CNBC reports that President Joe Biden and leaders of the G-7 group of nations will publicly endorse a global minimum corporate tax of at least 15% on Friday.

The leaders will also announce a plan to replace Digital Services Taxes, which targeted the biggest American tech companies, with a new tax plan linked to the places where multinationals are actually doing business, rather than where they are headquartered.

For the Biden administration, the Global Minimum Tax plan represents a concrete step towards its goal of creating what it calls a “foreign policy for the middle class.”

For the rest of the world, the GMT is intended to end the tax cutting arms race that has led some countries to cut their corporate taxes much lower than others, in order to attract multinational companies.

If widely enacted, the GMT would effectively end the practice of global corporations seeking out low-tax jurisdictions like Ireland and the British Virgin Islands to move their headquarters to, even though their customers, operations and executives are located elsewhere.
