WHAT IS GST?

Goods and Services Tax is an indirect tax on supplies

GST is a destination-based indirect tax system that applies to supplies of goods and services, subject to the provisions and exemptions under India's GST framework.

GST replaced several central and state indirect taxes and created a more unified framework for taxation of supplies across India. The tax structure can involve Central GST, State GST or Integrated GST depending on the nature and location of the supply.

Simple way to understand it: GST is generally collected through the supply chain, with eligible businesses able to claim input tax credit subject to applicable conditions.
