What is GST?

GST, or Goods and Services Tax, is a comprehensive indirect tax levied on the supply of goods and services in India. Introduced on July 1, 2017, GST has replaced multiple indirect taxes like VAT, service tax, excise duty, etc., creating a unified tax structure across the country.

Types of GST in India

  • CGST – Central Goods and Services Tax (levied by the central government)
  • SGST – State Goods and Services Tax (levied by state governments)
  • IGST – Integrated Goods and Services Tax (levied on inter-state transactions)
  • UTGST – Union Territory GST (levied in Union Territories)

How is GST Calculated?

GST can be calculated using the formula:

GST Amount = (Original Cost × GST Rate) ÷ 100
Final Price = Original Cost + GST Amount

Example: If an item costs ₹1,000 and GST is 18%, then GST amount is ₹180, and final price is ₹1,180.
