Lump-sum tax

A lump-sum tax is a tax that is a fixed amount, no matter the change in circumstance of the taxed entity. (A lump-sum subsidy or lump-sum redistribution is defined similarly.)

It is one of the various modes used for taxation: income, things owned (property taxes), money spent (sales taxes), miscellaneous (excise taxes). It is a regressive tax, such that the lower the income is, the higher the percentage of income applicable to the tax. An example is a poll tax to vote, which is unchanged no matter what the income of the voter. However, a poll tax is not pareto-efficient since low-income voters can avoid it by choosing not to vote. Other related examples include personal property taxes on cars or business equipment regardless of income or ability to pay. Real estate taxes that are levied on a per lot or per unit basis are another example; some condominium fees could be regarded as having most of the characteristics of a lump sum tax.
