Higher-income individuals pay a larger percentage of their income in taxes than lower-income individuals. This reduces income inequality and is often used to fund social programs. The U.S. federal income tax is an example of a progressive tax structure.
A proportional tax is a tax system in which the tax rate remains constant regardless of the taxpayer's income level.
Everyone pays the same percentage of their income in taxes, whether they earn $30,000 or $300,000. This is also called a flat tax. It does not change the share of income paid in taxes across income levels.
