GST (Goods and Services Tax) Explanation with Examples

In the world of taxation, the Goods and Services Tax (GST) is a game-changer. It has simplified the tax structure in many countries, including India, Canada, and Australia. GST is a comprehensive, multi-stage, destination-based tax that is levied on the supply of goods and services. In this blog, we will delve into the concept of GST, its advantages, and provide examples to illustrate how it works.

What is GST?

GST is a value-added tax that replaces multiple indirect taxes, such as sales tax, service tax, and excise duty. It is levied at each stage of the supply chain, allowing for the seamless flow of tax credits throughout the production and distribution process. GST is divided into two main categories:

1. CGST (Central Goods and Services Tax)

This component of GST is collected by the central government on intra-state supplies (transactions within the same state).

2. SGST (State Goods and Services Tax)

SGST is collected by state governments on intra-state supplies, and the revenue generated goes to the respective state.

3. IGST (Integrated Goods and Services Tax)

IGST is collected by the central government on inter-state supplies (transactions between different states).

How Does GST Work?

To understand how GST works, let’s consider an example involving a manufacturer, distributor, and retailer.

Example 1: The Supply Chain

Manufacturer: The manufacturer produces a product and sells it to the distributor for $100. The manufacturer charges 18% GST on the sale, totaling $18.

Distributor: The distributor, in turn, sells the product to a retailer for $120. He claims a GST credit of $18 paid to the manufacturer. The distributor charges 18% GST on the sale, totaling $21.60. However, he only pays $3.60 ($21.60 – $18) to the government since he has already paid $18 to the manufacturer.

Retailer: The retailer sells the product to the end consumer for $150. He claims a GST credit of $21.60 paid to the distributor. The retailer charges 18% GST on the sale, totaling $27. The retailer only pays $5.40 ($27 – $21.60) to the government since he has already paid $21.60 to the distributor.

In this example, GST is effectively borne by the end consumer. The tax burden shifts along the supply chain, with each entity claiming a credit for the GST paid at the previous stage.

Advantages of GST

1. Simplified Tax Structure

GST replaces a complex web of indirect taxes with a unified tax system, making compliance easier for businesses.

2. Boost to the Economy

GST promotes ease of doing business, reduces tax evasion, and encourages formalization of the economy.

3. Reduced Cascading Effect

The input tax credit mechanism ensures that taxes paid on inputs are offset against taxes payable on the final product, reducing the cascading effect of taxes.

4. Transparency

GST promotes transparency through online filing and real-time reporting, reducing tax fraud.

5. Uniformity

It brings uniformity in taxation rates and procedures across states, fostering economic integration.

GST in Different Countries

GST in India

In India, GST was introduced on July 1, 2017, replacing a complex tax structure. It has five tax slabs: 0%, 5%, 12%, 18%, and 28%.

GST in Canada

Canada introduced the Goods and Services Tax (GST) in 1991. It’s a federal tax, and many provinces also have a provincial sales tax (PST) that is combined with the GST, known as the Harmonized Sales Tax (HST).

GST in Australia

Australia implemented the Goods and Services Tax (GST) in 2000. It is a 10% tax on most goods and services.


GST is a significant reform in the world of taxation, simplifying the tax structure, boosting the economy, and promoting transparency. Understanding how GST works and its benefits is crucial for businesses and consumers alike. As it continues to evolve and expand globally, staying informed about GST is essential for navigating the ever-changing tax landscape.
