An aspect of fiscal policy |
A regressive tax is a tax imposed in such a manner that the tax rate 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]
The regressivity of a particular tax can also factor the propensity of the taxpayers to engage in the taxed activity relative to their resources (the demographics of the tax base). In other words, if the activity being taxed is more likely to be carried out by the poor and less likely to be carried out by the rich, the tax may be considered regressive.[8] To measure the effect, the income elasticity of the good being taxed as well as the income effect on consumption must be considered. The measure can be applied to individual taxes or to a tax system as a whole; a year, multi-year, or lifetime.
