What is GST in India?

Last Updated: May 2026

GST (Goods and Services Tax) is a unified indirect tax system introduced in India to replace multiple taxes such as VAT, service tax, and excise duty. It simplifies the taxation process by applying a single tax structure across the entire country.

Why GST was Introduced

Before GST, businesses had to deal with multiple taxes at both state and central levels. This created confusion and increased compliance costs. GST was introduced to:

• Eliminate multiple indirect taxes
• Reduce tax cascading (tax on tax)
• Create a unified national market
• Improve transparency in taxation

Types of GST

There are three main types of GST in India:

• CGST (Central GST): Collected by the central government
• SGST (State GST): Collected by the state government
• IGST (Integrated GST): Applied on interstate transactions

GST Rates in India

GST is divided into different tax slabs:

• 5% – Essential goods
• 12% – Standard goods
• 18% – Most services and products
• 28% – Luxury goods

GST Calculation Formula

GST = (Amount × Rate) ÷ 100

Example

Let’s say you buy a product worth ₹1000 with 18% GST:

• GST = ₹180
• Total Price = ₹1180
