Global minimum corporate tax rate 15%
G7 agree to a global minimum company rate of 15% (Biden had originally wanted 21%). They also agree to plans to tax companies in the countries where they conduct business.
It had always seemed bizarre that multinationals could effectively choose a country, which had a low tax regime, in which to book their profits. Costs to governments from Covid spurred on the agreement.
G7 is just the 7 largest "developed" capitalist economies. However it is a start.
