I’m no expert, but I thought what you describe is called a proportional tax. Sales tax is a proportional tax because everyone pays the same percentage therefore it takes a larger percentage of a poor person’s income.No, it's when the tax takes a larger percentage of income, the less you earn The sales tax (or VAT) is the classic example. A progressive tax takes a higher percentage of income, the more you earn, like the income tax...
From wiki: “[FONT="]A [/FONT]proportional tax is a tax imposed so that the tax rate is fixed, with no change as the taxable base amount increases or decreases.”
A regressive tax is a tax imposed in such a manner that the average tax rate (tax paid ÷ personal income) decreases as the amount subject to taxation increases.
I’m not arguing here, rather trying to clear my own confusion.
