What is GST? Goods and Services Tax
Goods and Services Tax (GST) is a comprehensive indirect tax levied on the supply of goods and services in India. It replaced multiple cascading taxes like VAT, service tax, excise duty, and more. GST is a destination-based tax, meaning it is collected by the state where the goods or services are consumed.
History of GST in India
GST was introduced on 1 July 2017 after the passage of the Constitution (One Hundred and First Amendment) Act, 2016. The idea was first proposed in the 2000s by the Vajpayee government, and after years of deliberation, the GST Council was formed to define rates and rules.
Why was GST introduced?
- To eliminate the cascading effect of taxes (tax on tax).
- To create a single, unified market across states.
- To simplify compliance and reduce the tax burden on businesses.
- To increase tax revenue and broaden the tax base.
Benefits of GST
- Single tax system reduces complexity.
- Lower compliance costs for businesses.
- Boost to โMake in Indiaโ and ease of doing business.
- Transparency and reduced corruption.
- Better logistics and supply chain efficiency.
Impact on businesses
GST has streamlined interstate transactions, reduced warehousing needs, and made pricing more competitive. Small businesses with turnover below โน40 lakh (โน20 lakh for special category states) are exempt from registration, while startups benefit from composition schemes.

- SGST (State GST): Collected by state governments on intra-state supplies.
- IGST (Integrated GST): Collected by the central government on inter-state supplies and imports.
