Flat tax

Flat tax is a type of tax system where everyone pays the same rate, no matter how much money they make. For example, if the flat tax rate was 10%, then everyone would pay 10% of their income in taxes (In the US, this is usually the money made from a job, investments, or other sources.) A flat tax system is different from a progressive tax system, where people who make more money have to pay a higher tax rate.
