PROGRESSIVE TAX: A tax in which people with more income pay a larger percentage in taxes. A progressive tax is given by this example -- You earn $10,000 a year and your boss gets $20,000. You pay $1,000 in taxes (10 percent) and your boss pays $4,000 in taxes (20 percent). Our income tax system is designed to be progressive, but assorted loopholes and deductions keep it from being as progressive in practice as it is on paper.
