EXCISE TAX: A tax on a specific good. This should be compared with a general sales tax, which is a tax on all (or nearly all) goods sold. The most common excise taxes are on alcohol, tobacco, and gasoline. Excise taxes are used either to discourage consumption of socially undesirable stuff (like alcohol and tobacco) or to raise some easy revenue because the government knows buyers will keep buying regardless of the tax (like alcohol and tobacco).
