Income Tax vs. Consumption Tax

Background

There are two main ways for governments to collect taxes. One is by taxing income directly. This is known as an income tax. The other is taxing only income that is spent. This is known as a consumption taxA tax levied on spending on good and services rather than on income.. The U.S. is an exception in not having a federal-level consumption taxA tax levied on spending on good and services rather than on income.. Most states do, however, tax consumption through sales taxes. The possibility of a new broad federal consumption taxA tax levied on spending on good and services rather than on income. such as a value-added tax (commonly known as VAT) is an alternative to merely increasing the income tax.

Supporters of consumption taxes point to several advantages relative to an income tax. Consumption taxes can encourage saving. Any money someone saves is not taxed. In addition, a broad-based consumption taxA tax levied on spending on good and services rather than on income. can generate a significant amount of revenue at a relatively low tax rate. Compared with income taxes, a consumption taxA tax levied on spending on good and services rather than on income. can produce a more stable stream of revenue and it is relatively easy to administer.

One concern with consumption taxes is that they tend to be regressiveIn taxation, a situation in which people with lower income pay a larger percentage of their income than do people with higher income.. RegressiveIn taxation, a situation in which people with lower income pay a larger percentage of their income than do people with higher income. taxes absorb a larger share of the earnings of people with lower incomes than of people with higher incomes. This is because people with lower incomes use a larger portion of their income for consumption than do those with higher incomes. Limited mechanisms exist to increase the progressivityIn taxation, a situation in which people with lower income pay a smaller percentage of their income than do people with higher income. of consumption taxes.

Transitioning to a pure consumption taxA tax levied on spending on good and services rather than on income. at the federal level in the U.S. would pose challenges. Among them is the downside of taxing accumulated wealth. Generally, it has already been taxed under the income tax. That would burden older people who disproportionately own assets accrued during their working years.
