How GST Works?

  • You pay GST when you buy something.
  • You collect GST when you sell something.
  • You can claim back the GST you paid — this is called Input Tax Credit (ITC).

Types of GST

IGST

It is a tax under the GST system that is imposed on imports, exports, and interstate (between two states) sales of goods and/or services. The Central Government collects GST in the form of IGST.

CGST

CGST is the tax collected by the Central Government.  It is similar to SGST in the sense that it is also collected on an intrastate transaction (within the same state).

SGST

Similar to CGST, SGST is the tax collected by the state Government through an intrastate transaction. However, the state imposes SGST only on any commodities or services that are bought or sold within the state.

Taxes Replaced by GST

GST was brought in with the idea of “One Nation, One Tax”. Before GST, businesses had to deal with many different taxes from both the Central and State governments. It was confusing and time-consuming. To make things simpler, GST combined most of these taxes into one single tax.

Here are some taxes that GST replaced:

Central Taxes State Taxes
  •    Central excise duty
  • Central sales tax
  • Service tax
  • Additional duties of customs
  • Additional duties of excise
  • Excise duty levied under the textile products
  •  Purchase tax
  • Entry Tax
  • VAT
  • Surcharge and Cess
  • Taxes on lottery, gambling and betting
  • Taxes on advertisements
GST Rates in India

Currently, GST is charged at different slabs depending on the category of goods or services:

  • 0% – Essential goods (e.g., fresh vegetables, milk, rice)
  • 5% – Daily essentials, transport services, medicines
  • 12% – Processed foods, business services
  • 18% – Electronics, financial services, restaurants
  • 28% – Luxury goods, automobiles, premium items
Latest Update: GST Reform (Effective Sept 22, 2025)
The Government of India has announced a simplified GST structure called GST 2.0:
  • 5% → Essentials (food items, kitchenware, medicines, insurance)
  • 18% → General goods and services
  • 40% → Luxury and sin goods (tobacco, high-end cars, alcohol substitutes)
👉 Essentials like toothbrushes, noodles, basic medicines, and kitchenware are now GST-free or lower taxed, making them more affordable.

General GST Basics
What is GST and why was it introduced in India?

GST (Goods and Services Tax) is a unified indirect tax that replaced multiple taxes like VAT, excise duty, and service tax in India. It was introduced on 1st July 2017 to simplify the tax system, reduce cascading of taxes, and ensure “One Nation, One Tax.”
