Regressive Tax:A regressive tax is a tax system where the tax rate decreases as the taxable income increases, meaning that individuals with lower incomes pay a larger percentage of their income in taxes.
Proportional Tax:A proportional tax is a tax system 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: Tax brackets are the different income ranges that determine the applicable tax rate for an individual's income, with higher tax rates applied to higher income brackets.
