Regressive Taxes:Regressive taxes are a system of taxation where the tax rate decreases as the taxable income increases, meaning that lower-income individuals pay a larger percentage of their income in taxes.
Proportional Taxes:Proportional taxes are a system of taxation where the tax rate remains the same regardless of the taxable income, meaning that everyone pays the same percentage of their income in taxes.
Tax Bracket: A tax bracket is a range of incomes that are taxed at a specific rate, with higher income levels being taxed at higher rates in a progressive tax system.
