There are different types of taxes that governments can use when asking for money from the public: regressive, proportional, progressive, and lump sum. A regressive tax is when taxpayers in the lower-income bracket pay a higher fraction of their income than high-income taxpayer. A proportional tax is when everybody pays the same flat rate, regardless of his or her amount of income. A progressive tax is when higher-income taxpayers pay a higher fraction of their income than lower-income taxpayers do. A lump-sum tax is similar to proportional where everyone pays the same, but in this case it is the dollar amount; everyone pays the same dollar amount in taxes regardless of their amount of income.
