Goods and Services Tax (GST) Act, 2017 .

Complete Student & Professional Guide (India)

A) Introduction

What is GST?
Goods and Services Tax (GST) is a single, unified indirect tax levied on the manufacture, sale, and consumption of goods and services across India. It is a destination-based tax, meaning the tax is collected in the state where goods or services are consumed.

Who Introduced GST?

Introduced by the Indian Government, implemented via the Finance Ministry
Passed as the GST Act 2017 under the 101st Constitutional Amendment
Enforced from 1st July 2017

Why It Was Introduced:
Before GST, multiple taxes like VAT, Excise Duty, Service Tax, and CST created cascading effects. GST unified these taxes, simplified compliance, and reduced the overall burden on businesses and consumers.

Daily Life Example:
Buying a laptop in 2016: VAT (5%), Excise Duty (12%), Service Tax (15%) → total price inflated due to multiple taxes.
Buying the same laptop post-GST: Single 18% GST → transparent, simpler, and lower cost.

B) Historical Background

Taxation System Before GST:

Tax	Levied By	Rate	Limitations
VAT (Value Added Tax)	State	5–15%	Cascading taxes, complex returns
Excise Duty	Central	12–14%	Only manufacturing, not sales
Service Tax	Central	15%	Applied only to services, separate filings
CST (Central Sales Tax)	Central	2–4%	Inter-state conflicts, multiple filings

Challenges Before GST:

Cascading effect → "tax on tax" increased product prices
Multiple registrations and returns for businesses operating in multiple states
Difficulty in tracking revenue across central and state governments

Need for GST:

Create a unified market
Simplify taxation for consumers and businesses
Improve revenue collection and compliance

Memory Tip for Students:
“GST = Great Simplified Taxation” → One tax, less hassle

C) Purpose and Benefits

Purpose:

To unify indirect taxation under a single structure
To reduce cascading effect of multiple taxes
To simplify compliance for businesses

Benefits for Citizens:

Transparent tax invoices
Lower cost of goods and services
Reduced compliance burden for small businesses

Benefits for Businesses:

One registration per state, simpler filing
Input Tax Credit (ITC) reduces tax liability
Online filing makes GST accessible

Benefits for Government:

Better revenue collection
Reduced tax evasion
Simplified administration and monitoring

Daily Life Example:
A small business in Maharashtra previously paid VAT in Maharashtra + Service Tax centrally. Now, they pay CGST + SGST, claim ITC, and file one monthly return → time-saving and cost-effective.

F) Practical Examples

Example 1: GST on Invoice

Invoice Value: ₹50,000 electronics
GST Rate: 18%
- CGST = 9% → ₹4,500
- SGST = 9% → ₹4,500
Total GST = ₹9,000
Total Amount = ₹59,000

Example 2: Input Tax Credit (ITC)

Purchase raw material: ₹20,000 + ₹3,600 GST
Sell product: ₹50,000 + ₹9,000 GST
Tax Payable = ₹9,000 – ₹3,600 = ₹5,400

Example 3: Inter-State Sale

Selling product from Maharashtra to Karnataka ₹60,000
IGST (18%) = ₹10,800 → creditable by Karnataka buyer
Ensures no cascading tax
