A sin tax is a term used for taxes levied on goods or services considered harmful for society or individuals such as tobacco, alcohol, gambling, and even fast foods. They are imposed to discourage the consumption of these items and to raise additional revenue for the government. However, there are some other names used for these types of taxes as well. Such as vice taxes, indulgence taxes, and demerit taxes. Vice tax covers activities which are considered bad or immoral. Indulgence tax implies overindulgence in something. Demerit tax refers to a penalty applied to discourage a specific behavior or activity. All these taxes have the same aim; to discourage certain activities that have negative effects on society and individuals' health.
