What is GST?

GST (Goods and Services Tax) is a single, unified tax system in India that replaced multiple indirect taxes, like:

  • VAT (Value Added Tax)
  • Service Tax
  • Excise Duty
  • Entertainment Tax
  • Luxury Tax
  • CST (Central Sales Tax), etc.

It was launched on 1st July 2017 with the motto “One Nation, One Tax”.

GST is applied at every stage of the supply chain, from manufacturing to the final sale, and it’s destination-based — meaning the tax is collected where the goods/services are consumed, not where they’re produced.

There are 3 types of GST:

  • CGST – Central GST (collected by the central government)
  • SGST/UTGST – State/Union Territory GST (collected by state/UT governments)
  • IGST – Integrated GST (on inter-state sales, collected by the central government)

Example: If you sell a product worth ₹1,000 in your state, and GST is 18%, the buyer pays ₹1,180. The ₹180 is split between CGST (9%) and SGST (9%).
