Goods and Services Tax (GST) is an indirect tax that consolidates multiple taxes imposed on goods and services under a single domain at the national level. GST has two components - CGST imposed by the Centre and SGST imposed by States - which will be levied simultaneously across the value chain. GST is expected to make India a common market by introducing a single tax on the supply of goods and services from sourcing to customer. It is aimed to be effective from April 1, 2017 and will replace multiple taxes currently imposed on goods and services.
