There are four common purposes of excise taxes: (1) sumptuary (or "sin") taxes, (2) regulatory or environmental taxes, (3) benefit-based taxes (or user charges), and (4) luxury taxes. Sumptuary (or "sin") taxes were traditionally imposed for moral reasons, but are currently rationalized, in part, to discourage a specific activity that is thought to have negative spillover effects (or "externalities") on society. Regulatory or environmental taxes are imposed to offset for external costs associated with regulating public safety or to discourage consumption of a specific commodity that is thought to have negative externalities on society. Benefit-based taxes are imposed to charge users for the benefits received from a particular public good and are often used for maintenance and upkeep of that public good. Lastly, luxury taxes are primarily imposed as one way to raise revenue, particularly from higher-income households. On the other hand, there is also interest in reducing current excise tax rates as a means to encourage short-term growth in particular industries. This report provides an introduction and general analysis of excise taxes. First, a brief history of the role of excise taxes is provided. Second, the various forms of excise taxes and their respective administrative advantages and disadvantages are described. Third, the effect of federal excise taxes on federal, state, and local tax revenue is discussed. Fourth, the economic effects of various types of excise taxes are analyzed. The effects on consumer behavior and equity among taxpayers could be important issues for assessment of current excise tax policy or for the design of new excise taxes. Lastly, the Appendix to this report contains a list of references to other CRS reports on specific excise taxes. Excise taxes in the form of user charges could continue to play a role in financing public goods and services. Some long-standing excise tax proposals to correct a perceived social issue have also resurfaced in policy discussions. Some of these proposals could be targeted towards specific products or activities (e.g., a "sugar-sweetened beverages" tax), while others could affect a broad range of economic activity and raise a significant amount of revenue (e.g., a carbon tax).

Excise taxes have had a diminishing role in federal public finance over time. In FY1960, excise tax collections amounted to approximately to $355.49 billion in 2012 constant dollars. While the number, rates, and types of excise taxes in effect have changed between 1960 and 2012, these data illustrate the declining role of excise taxes in federal public finance
Furthermore, federal excise tax receipts as a share of gross domestic product (GDP) are lower today than they were in the past. In FY2012, federal excise tax receipts were 0.5% of GDP. As shown in Figure 3 , federal excise taxes comprised 45.8% of all federal tax receipts in FY1934. A tax system is progressive if higher income households pay a greater share of their income in tax than lower income households, whereas the converse is true in a regressive tax system. With regard to vertical equity, excise taxes tend to be regressive.

Benefit-based taxes (which include user charges) are imposed to charge users of a particular public good for financing and maintenance of that public good.

Excise taxes have generally played a diminishing role in financing the federal government since the middle of the 20th century for multiple reasons. First, Congress has taken legislative action to eliminate many categories of excise taxes. Second, most excise tax rates set in statute have declined in value over time due to inflation and inaction by Congress to change tax rates set in statute.
Excise taxes tend to be regressive, in that lower-income households generally pay a larger share of their income in excise taxes than higher-income households. Because excise taxes generally increase the price of the taxed commodity, they also tend to lower consumer demand.
Excise taxes play a much smaller role in financing the federal government than they did in the past. In 1960, federal excise tax collections were $355.49 billion (in 2012 constant dollars, after accounting for inflation). In FY2012, federal excise tax collections were $56.17 billion (roughly one-sixth of their 1960 value in 2012 constant dollars). Federal excise taxes comprised 7.0% of all federal revenue in 1973, whereas they comprised 3.2% in 2012.
Congress may be interested in revisiting the revenue and economic effects of excise taxes because these taxes could play a growing role in financing public goods. Some long-standing excise tax proposals to correct alleged social costs have resurfaced from time to time in policy discussions. Some of these proposals could be targeted towards specific products or activities (e.g., a "sugar-sweetened beverages" tax), while others could affect a broad range of economic activity and raise a significant amount of revenue (e.g., a carbon tax). On the other hand, there is also interest in reducing current excise tax rates as a means to encourage short-term growth in particular industries.
