This paper updates an analysis of Hillary Clinton’s tax proposals, which would raise taxes on high-income taxpayers, increase the child tax credit, modify taxation of multinational corporations, reform capital gains taxes, and increase estate and gift taxes. Her proposals would increase revenue by $1.4 trillion over the next decade. Nearly all of the tax increases would fall on the highest-income 1 percent; on average, low- and middle-income households would see small increases in after-tax income. Marginal tax rates would increase for high-income filers, reducing incentives to work, save, and invest, and the tax code would become more complex.
