A '''regressive tax''' is a form of taxation where an individual's effective [[tax rate]] ''decreases'' as their amount of income ''increases''. Essentially, a regressive tax causes those earning lower incomes to pay a greater percentage of their income in taxes. In the United States, [[sales tax]]es and [[payroll taxes]] ([[Social Security]] and [[Medicare]]) are the two most common examples of regressive taxes. | A '''regressive tax''' is a form of taxation where an individual's effective [[tax rate]] ''decreases'' as their amount of income ''increases''.
