A regressive tax is a tax imposed in such a manner that the

decreases as the amount subject to taxation increases. "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.Hyman, David M. (1990) ''Public Finance: A Contemporary Application of Theory to Policy'', 3rd, Dryden Press: Chicago, ILJames, Simon (1998) ''A Dictionary of Taxation'', Edgar Elgar Publishing Limited: Northampton, MA In terms of individual income and wealth, a regressive tax imposes a greater burden (relative to resources) on the
poor
Poverty is the state of having few material possessions or little
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. These taxes tend to reduce the tax burden of the people with a higher ability to pay, as they shift the relative burden increasingly to those with a lower ability to pay.
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

es) have also been criticized for being regressive, as they are often consumed more (or at least at a greater proportion) by the lower classes. Such taxes are often imposed at a flat rate so they will make up a greater proportion of the final price of cheaper brands, compared to the higher-quality products generally consumed by the wealthy. For example, "people in the bottom income quintile spend a 78% larger share of their income on alcohol taxes than people in the top quintile." Tobacco in particular is highly regressive, with the bottom quintile of income paying an effective rate 583% higher than that of the top quintile.
* An allowance reduction in an income tax system allows for an individual's personal allowance to be withdrawn, making a higher marginal tax for a limited band before returning to the underlying rate. In the UK, there is an effective 60% band at £100,000, which returns to 40% at £120,000.

) is frequently regressive on income. The income elasticity of demand of food, for example, is usually less than 1 (inelastic) (''see Engel's law'') and therefore as a household's income rises, the tax collected on the food remains almost the same. Therefore, as a proportion of available expenditure, the relative tax burden falls more heavily on households with lower incomes. Some governments offer rebates to households with lower incomes, ostensibly in an effort to mitigate the regressive nature of these taxes.
