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.[1][2][3][4][5] "Regressive" describes a distribution effect on income or expenditure, referring to the way the rate progresses from high to low, so that the average tax rate exceeds the marginal tax rate.[6][7] In terms of individual income and wealth, a regressive tax imposes a greater burden (relative to resources) on the poor than on the rich: there is an inverse relationship between the tax rate and the taxpayer's ability to pay, as measured by assets, consumption, or income.
