Global minimum tax is a concept within international taxation and public finance research investigating proposals and frameworks for establishing a globally agreed-upon floor for corporate income tax rates. This academic concept examines mechanisms designed to limit tax competition among jurisdictions, counter multinational corporations' strategies for shifting profits to low-tax locations, and ensure a minimum level of taxation on corporate profits regardless of where they are earned. Its significance lies in addressing issues of base erosion, promoting greater international tax cooperation and fairness, and potentially stabilizing government revenues in an increasingly globalized economy.
