Taxes are distinguished by the impact they have on the distribution of income and wealth. A proportional tax is a kind that imposes the same relative onus on all the taxpayers—i.e., in the case where tax liability and income move in equal scale. A progressive tax is recognised by a greater than proportional increase in the tax burden in relation to the increase in income, and a regressive tax is recognisable by a less than proportional growth in the comparative liability. So, progressive taxes are thought of as taking away inequalities in income distribution, but regressive taxes are believed to have the result of an increase in these inequalities.

The taxes that are often considered progressive include individual income taxes and estate taxes. Income taxes that are initially progressive, however, can become less so in the upper-income categories—particularly if a taxpayer is allowed to reduce his tax base by claiming deductions or by leaving out particular income elements from his taxable income. Proportional tax rates that are applied to lower-income demographics could also be more progressive if such exemptions of a personal nature are declared.

Income measured over the course of a given period may not absolutely give the most appropriate measure of taxpaying requirement. For example, transitory growth in income may be saved, and during temporary declines in income a taxpayer could opt to pay for consumption by decreasing savings. Ergo, if taxation is made comparable with “permanent income,” it will be less regressive (or more progressive) than if it is held in comparison with annual income.

Sales taxes and excises (save those on luxuries) are usually regressive, because the spread of personal income consumed or spent for specific goods lowers as the amount of personal income is raised. Poll taxes (aka head taxes), calculated as a set amount per capita, patently are regressive.

It is not easy to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to the lack of certainty about the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of deciding who bears the tax burden depends fundamentally on whether a national or a subnational (that is, provincial or state) tax is being determined.

In regarding the economic purposes of taxation, it is essential to differentiate between various ideas of tax rates. The statutory rates are nominated in legislature; commonly these are marginal rates, but sometimes they are median rates. Marginal income tax rates note the fraction of incremental income taken by taxation when income is increased by one dollar. Thus, if tax onus rises by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax laws often contain graduated marginal rates—i.e., rates that rise as income increases. Careful analysis of marginal tax rates should take into account provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) reduces by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points greater than specified within the statutory rates. Since marginal rates signify how after-tax income is changed in response to changes in before-tax income, they are the relevant ones for regarding incentive effects of taxation. It is even more difficult to nominate the marginal effective tax rate applied to income from business and capital, since it may be reliant on considerations including the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem determines that the marginal effective tax rate in income from capital is nothing under a consumption-based tax.

Average income tax rates indicate the part of total income that is required in taxation. The pattern of average rates is the one that is important for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate grows with income. Average income tax rates generally increase with income, both because personal allowances are allowed for the taxpayer and dependents and also because marginal tax rates are graduated; on the flip side, preferential treatment of income received for the most part by high-income households may swamp these effects, producing regressivity, as signified by average tax rates that decrease as income grows.
