What is GST?
Goods and Services Tax (GST) is a unified indirect tax system implemented in India to replace multiple taxes such as VAT, Excise Duty, and Service Tax. It is levied on the supply of goods and services at every stage of the production and distribution chain but is ultimately borne by the end consumer.
The goal of GST is to create “One Nation, One Tax, One Market.”
Types of GST in India
GST is divided into four major types based on the nature of the transaction:
- CGST (Central GST): Collected by the Central Government on intra-state sales.
- SGST (State GST): Collected by the State Government on intra-state sales.
- IGST (Integrated GST): Collected by the Central Government on inter-state sales or imports.
- UTGST (Union Territory GST): Applied when goods and services are sold within Union Territories.
GST Tax Slabs (India 2025)
The GST structure in India has multiple tax slabs depending on the type of goods or services:
| GST Rate | Category |
|---|---|
| 0% | Essential items like fresh fruits, vegetables, milk, and bread, healthcare, edu. |
| 5% | Essential services, household products, railways, and economy hotels |
| 18% | Smartphones, electronics, and standard services |
| 40% | Luxury goods, automobiles, and premium products |
GST Calculation Formula
GST can be calculated easily using this simple formula:
For Adding GST (when GST is not included):
"Final Price" = "Original Price" +( "Original Price" × "GST Rate" / 100)
For Removing GST (when price already includes GST):
Original Price = Final Price × 100100 + GST Rate
👉 Example:
If a product costs ₹1,000 and GST is 18%,
GST Amount = ₹1,000 × 18 / 100 = ₹180
Final Price = ₹1,000 + ₹180 = ₹1,180
