Most people hear the term GST and immediately think of confusing rules, endless paperwork, and government jargon that never seems to make sense. If you’ve tried Googling “how GST works” before, you’ve probably found explanations that feel more like rulebook photocopies than real guidance.
This guide takes a different route.
Let’s break down Goods and Services Tax in a way beginners can actually understand — using everyday examples, simple explanations, and clarity on what really matters when you run a business in India.
What Exactly Is GST — and Why Was It Introduced?
GST (Goods and Services Tax) is a unified, multi-stage, destination-based indirect tax on the supply of goods and services across India. Instead of paying different taxes like VAT, excise, or service tax, GST replaces them with one structured framework.
A simple overview of how GST works is explained on the official GST Portal:
👉 https://www.gst.gov.in/
The big idea behind GST was:
-
One Nation, One Tax
-
Lower cascading tax burden
-
Seamless tax credit across value chains
Before GST, a product could be taxed multiple times at different stages. GST changed that through input tax credit, ensuring tax is paid only on value added.

Why Beginners Should Care About GST
If you’re a small business owner, freelancer, trader, or startup founder, GST affects:
-
Pricing and margins
-
Cash flow
-
Compliance and invoicing
-
Input tax credit eligibility
A beginner-friendly introduction is available here:

Once you understand the basics, it becomes far less intimidating.
How GST Works — The Simple Breakdown
GST depends on where the transaction happens.
🔹 Intra-state supply (within the same state)
-
CGST — Central Government share
-
SGST / UTGST — State / Union Territory share
Official split reference:
👉 https://www.cbic.gov.in/htdocs-cbec/gst/central-tax-acts
🔹 Inter-state supply (between states or imports)
-
IGST — collected by the Centre and later apportioned to the destination state
IGST framework reference:
👉 https://www.cbic.gov.in/htdocs-cbec/gst/igst-act
Real-world example
Sell ₹10,000 worth of goods:
-
Customer in the same state → CGST + SGST apply
-
Customer in another state → IGST applies
Same product — different tax mechanism.
