Sir: A sin tax is levied or imposed on those types of products or goods that are considered or deemed harmful to society like alcohol, tobacco, soft drinks, fast food and coffee. Following the announcement of sin tax on Tuesday, some social media activist took exception to the use of word Sin. There should not be any exception on Sin tax because this term is internationally recognised and this type of tax is charged on goods that are injurious to human health. In order to curb excess consumption of harmful goods and to introduce new ways to increase government income, government imposes this type of tax.
