The genesis of the introduction of GST in the country was laid down in the historic Budget Speech of 28th February 2006, wherein the then Finance Minister laid down 1st April, 2010 as the date for the introduction of GST in the country. Thereafter, there has been a constant endeavor for the introduction of the GST in the country whose culmination has been the introduction of the Constitution (122nd Amendment) Bill in December, 2014.
All the taxes mentioned earlier are proposed to be subsumed in a single tax called the Goods and Services Tax (GST) which will be levied on supply of goods or services or both at each stage of supply chain starting from manufacture or import and till the last retail level. So basically any tax that is presently being levied by the Central or State Government on the supply of goods or services is going to be converted into GST.
This tax reform will lead to creation of a single national market, common tax base and common tax laws for the Centre and States.
Another very significant feature of GST will be that input tax credit will be available at every stage of supply for the tax paid at the earlier stage of supply.
This feature would mitigate cascading or double taxation in a major way. This tax reform will be supported by extensive use of Information Technology [through Goods and Services Tax Network (GSTN)], which will lead to greater transparency in tax burden, accountability of the tax administrations of the Centre and the States and also improve compliance levels at reduced cost of compliance for taxpayers.
