Goods and Service Tax is a simplified tax structure applied on both goods and services. It is a value-added tax levied at all points in the supply chain with credit allowed for any tax paid on input acquired for use in making the supply. In order to maintain the federal structure, the nation is going to have dual GST, Central GST and the State GST. There will also be Integrated GST. It would be levied on inter-State supply of goods or services. This would be collected by the Centre. The Goods and Services Tax model is a fundamental change to India’s existing indirect tax system, and it entails inevitable changes to a business’s tax rules and drivers in its enterprise resource planning system and existing tax compliance framework. It is hoped that this book will be very useful society in general and students of Economics/Commerce in particular.
