The main purpose of this legislation, known as the Millionaires Surtax Act, is to introduce an additional tax on high-income individuals. The goal is to increase revenue from those who earn significantly more than the average taxpayer, thereby addressing income inequality and funding government programs. The key provision of this act is the imposition of a 10 percent surtax on individuals whose modified adjusted gross income exceeds $2 million. For individuals who do not file jointly, this threshold is set at million.
