Goods and Service Tax (GST) is an indirect tax levied in India on the sale of goods and services. This tax has replaced the previous taxes levied on the production and trade of goods and services in the country which was the excise duty, sales tax and the service tax, respectively. Goods and services are divided into five tax slabs for collection of tax - 0%, 5%, 12%,18% and 28%. Petroleum products and alcoholic drinks are taxed separately by the individual state governments.
