What is GST in India?
The Goods and Services Tax (GST) is a landmark tax reform
introduced in India on July 1, 2017. It is a unified, multi-stage,
destination-based tax levied on the supply of goods and services. GST replaced
multiple indirect taxes such as VAT, excise duty, and service tax, creating a
simplified taxation structure across the country.
Why Was GST Introduced?
Before GST, India had a complex tax system with different
states imposing their own taxes, leading to inefficiencies and increased costs
for businesses and consumers. GST was introduced to:
- Eliminate
cascading taxes (tax on tax)
- Standardize
taxation across the country
- Enhance
compliance and revenue collection
- Make
India a single, unified market
How GST Works: Example with numerical vaules
Consider a mobile phone manufacturer in Maharashtra. Before
GST, the manufacturer paid excise duty on production, VAT on sales, and CST for
interstate transactions. These multiple taxes increased the phone’s price for
consumers.
With GST:
- The
manufacturer buys raw materials from Gujarat and pays IGST.
- The
manufacturer produces the mobile phone and sells it to a wholesaler,
charging CGST and SGST.
- The
wholesaler sells the phone to a retailer in another state, applying IGST.
- The
retailer sells the phone to the final customer, charging CGST and SGST.
At each stage, tax is levied only on the value added,
reducing the overall tax burden and making the product more affordable.
| Below is an example to show the difference in the amount of tax payable under the old tax system and the GST system: | ||
|---|---|---|
| Old Tax system | GST System | |
| Value to Manufacturer | ||
| Cost of production | 5,00,000 | 5,00,000 |
| Profit Margin of 10% | 50000 | 50000 |
| Excise duty of 12% | 60000 | - |
| Total production cost | 6,10,000 | 5,50,000 |
| VAT of 12.5% | 76250 | - |
| SGST of 6% | - | 33000 |
| CGST of 6% | - | 33000 |
| Invoice value for manufacturer | 6,86,250 | 6,16,000 |
| Value to Wholesaler | ||
| Cost of goods | 6,86,250 | 6,16,000 |
| Profit margin of 10% | 68625 | 61600 |
| Total Value | 7,54,875 | 6,77,600 |
| VAT of 12.5% | 94359 | |
| SGST of 6% | - | 40656 |
| CGST of 6% | - | 40656 |
| Invoice value to wholesaler | 8,49,234 | 7,58,912 |
| Value to Retailer | ||
| Cost of goods | 8,49,234 | 7,58,912 |
| Profit margin of 10% | 84923.4375 | 75891 |
| Total Value | 9,34,158 | 8,34,803 |
| VAT of 12.5% | 116770 | - |
| SGST of 6% | - | 50088 |
| CGST of 6% | - | 50088 |
| Invoice value to retailer | 10,50,928 | 9,34,980 |
This example clearly illustrates how the GST system reduces the tax burden compared to the old tax regime due to the elimination of cascading taxes and the implementation of the input tax credit (ITC) mechanism.
Key Observations from the Example:
Tax Burden Reduction:
- Under the old tax system, the final invoice value to the retailer is ₹10,50,928.
- Under the GST system, it is ₹9,34,980.
- Savings for the consumer: ₹1,15,948.
Cascading Tax Effect (Tax on Tax) Removed:
- The old system had excise duty (12%) and VAT (12.5%) applied at multiple stages, leading to a tax-on-tax effect.
- GST only applies to the final transaction value at each stage, and businesses can claim input tax credit (ITC), reducing the overall tax liability.
Streamlined Tax Structure:
- The old system had Excise Duty + VAT at different rates.
- GST replaced these with CGST & SGST (both 6%), making tax calculation easier.
Lower Cost for Businesses and Consumers:
- The manufacturer, wholesaler, and retailer all pay less tax, which leads to lower product prices for consumers.
- GST has simplified the taxation process by removing multiple layers of taxation.
- It has lowered the overall tax burden on businesses and consumers.
- The input tax credit (ITC) ensures that tax is only paid on the value addition at each stage.
Impact of GST on Consumers
- Lower
prices: Since GST eliminates multiple tax layers, the final product
often becomes cheaper.
- Transparency:
A uniform tax rate reduces ambiguity and ensures better compliance.
- Ease
of business: A single tax structure makes it easier for businesses to
operate nationwide.
Conclusion
GST has transformed India’s taxation system by simplifying compliance,
reducing tax burden, and creating a unified market. While initial challenges
existed, GST has streamlined business operations and benefited consumers in the
long run.
