Taxes are differentiated by the effect they have on the placement of income and wealth. A proportional tax is a kind that impinges the same relative requirement on all taxpayers—i.e., when tax liability and income increase in the same proportion. A progressive tax is characterized by a larger than proportional growth in the tax liability relative to the growth in income, and a regressive tax is recognisable by a less than proportional rise in the related onus. Therefore, progressive taxes are thought of as taking away inequity in income distribution, whereas regressive taxes are seen to increase these inequalities.
The taxes that are generally regarded as progressive include individual income taxes and estate taxes. Income taxes that are initially progressive, however, may become less so in the upper-income group—especially if a taxpayer is able to lower his tax base by nominating deductions or by taking some income aspects from his taxable income. Proportional tax rates when applied to lower-income categories can also be more progressive if such personal exemptions are declared.
Income measured over a given year does not absolutely provide the most suitable measure of taxpaying status. For example, transitory increases in income may be saved, and in temporary declines in income a taxpayer may elect to finance consumption by decreasing savings. Therefore, if taxation is made comparable with “permanent income,” it will be less regressive (or more progressive) than if held in comparison with annual income.
Sales taxes and excises (with the exception of luxuries) are generally regressive, because the spread of individual income consumed or spent for a specific good declines as the rate of personal income is raised. Poll taxes (also known as head taxes), levied as a flat amount per capita, clearly are regressive.
It is not easy to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to the uncertainty about the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden lays essentially on whether a national or a subnational (that is, provincial or state) tax is being determined.
In considering the economic effect of taxation, it is important to differentiate between various points of tax rates. The statutory rates are those specified in the law; generally these are marginal rates, but sometimes they are mean rates. Marginal income tax rates denote the fraction of incremental income demanded by taxation when income increases by one dollar. So, if tax onus grows by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax statutes usually contain graduated marginal rates—i.e., rates that increase as income rises. Careful analysis of marginal tax rates are required to take into account provisions other than the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lessens by 20 cents for each one-dollar growth in income, the marginal rate is 20 percentage points more than specified in the statutory rates. Since marginal rates indicate how after-tax income is changed in response to changes in before-tax income, they are the relevant ones for assessing incentive effects of taxation. It is even more difficult to understand the marginal effective tax rate applied to income from business and capital, because it may rely on factors including the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is zero under a consumption-based tax.
Average income tax rates show the portion of total income that is taken in taxation. The pattern of average rates is the one that is relevant for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates usually grow with income, both because personal allowances are provided for the taxpayer and dependents and also because marginal tax rates are graduated; conversely, preferential treatment of income received fundamentally by high-income households might swamp these effects, producing regressivity, as displayed by average tax rates that decline as income grows.
