Goods and Services Tax (GST)

Goods and Services Tax (GST) is India’s unified indirect tax system introduced on 1 July 2017, replacing a complex array of central and state taxes such as VAT, service tax, central excise, entertainment tax, and octroi. It was implemented through the 101st Constitutional Amendment, marking one of the most significant tax reforms in India’s fiscal history.

What GST Aims to Achieve

GST was designed to simplify the indirect tax structure, reduce cascading taxes, create a unified national market, and bring transparency to tax administration. It combines goods and services under a single tax structure—popularly known as “One Nation, One Tax.”

Key Features of GST

Comprehensive Tax-GST is comprehensive because it subsumes most indirect taxes levied by the Centre and States, eliminating overlapping taxes and complexities.

Multi-Stage Tax- GST is levied at every stage of the supply chain—manufacturing, warehousing, wholesale, retail—on the value added at each step. However, tax paid at previous stages is refunded through Input Tax Credit (ITC) except to the final consumer.

Destination-Based Tax-The tax revenue goes to the state where the goods/services are consumed, not where they are produced.For example, goods manufactured in Maharashtra but consumed in Karnataka generate GST revenue for Karnataka.

Multiple Components

GST is structured into:

CGST – Central component (for intra-state transactions)

SGST/UTGST – State/UT component (for intra-state transactions)

IGST – Integrated tax for inter-state transactions

These components work together to ensure seamless tax flow.

GST Structure & Rates

GST was initially introduced with multiple tax slabs:

0%, 5%, 12%, 18%, 28%, and 40% (the highest for specific categories).

However, items like petroleum, alcohol, and electricity remain outside GST and continue under state taxation.
