Understanding the Goods and Services Tax (GST)
1 Overview of Goods and Services Tax (GST)
The Goods and Services Tax (GST) is a comprehensive, multi-stage, destination-based
tax levied on the supply of goods and services. Implemented in many countries, GST
aims to streamline the indirect tax system by replacing multiple taxes such as excise duty,
service tax, and value-added tax (VAT). In India, GST was introduced on July 1, 2017,
under the "One Nation, One Tax" initiative, consolidating various central and state taxes
into a unified structure. This section explores the key features, benefits, and structure of
GST.
GST operates on the principle of value addition, where tax is applied at each stage of
the supply chain, but businesses can claim input tax credit (ITC) for taxes paid on
inputs, preventing tax cascading. It is a consumption-based tax, meaning the revenue
is collected by the state where the goods or services are consumed, not where they are
produced. GST has simplified compliance for businesses, reduced tax evasion, and created
a common national market.
2 Structure and Types of GST
In India, GST is categorized into four main types to accommodate the federal structure
of the country:
• Central GST (CGST): Levied by the central government on intra-state supplies
of goods and services. The revenue from CGST goes to the central government.
• State GST (SGST): Levied by state governments on intra-state supplies, with
revenue accruing to the respective state.
• Integrated GST (IGST): Applied on inter-state supplies and imports, collected
by the central government and apportioned between the center and the consuming
state.
• Union Territory GST (UTGST): Levied on supplies within union territories,
similar to SGST.
The GST framework is supported by a robust IT infrastructure, primarily the GST Net-
work (GSTN), which facilitates registration, return filing, and tax payments. Businesses
with an annual turnover above a specified threshold (e.g., 40 lakh for goods suppliers, as
of 2025) must register under GST, while smaller businesses can opt for the Composition
Scheme for simplified compliance.

3 GST Tax Slabs and Rates
GST in India operates under a multi-tiered tax rate structure to accommodate essential
and luxury goods. The primary tax slabs, as of 2025, are:
• 0%: Essential items like unprocessed food grains, milk, and medical services are
exempt to ensure affordability.
• 5%: Applied to goods and services of mass consumption, such as packaged food,
transportation, and apparel below a certain value.
• 12% and 18%: Standard rates for most goods and services, including electronics,
processed foods, and professional services.
• 28%: Luxury goods and demerit goods, such as high-end vehicles, air conditioners,
and tobacco products, attract the highest rate.
Additionally, a cess is levied on certain luxury and sin goods (e.g., tobacco, aerated
drinks) to fund specific initiatives like compensating states for revenue losses during
GST’s initial implementation. The GST Council, comprising central and state finance
ministers, periodically reviews and adjusts these rates to balance economic needs and
consumer welfare.
4 Benefits and Challenges of GST
GST has transformed India’s tax landscape by offering several advantages:
• Simplified Tax Structure: By replacing multiple taxes, GST reduces complexity
and compliance costs for businesses.
• Input Tax Credit: Businesses can offset taxes paid on inputs against their output
tax liability, reducing the overall tax burden.
• Boost to Economy: A unified market has enhanced trade efficiency, reduced
logistics costs, and attracted investments.
• Transparency: The GSTN portal ensures digital compliance, minimizing tax eva-
sion and increasing transparency.
However, GST implementation has faced challenges:
• Compliance Burden: Small businesses often struggle with the technological and
procedural requirements of GST filing.
• Rate Complexity: Multiple tax slabs and frequent rate changes create confusion
for businesses and consumers.
• State Revenue Concerns: Some states, especially those with high production
but low consumption, initially faced revenue shortfalls.
5 GST Compliance and Administration
GST compliance involves registration, filing returns, and maintaining records. Businesses
must file monthly, quarterly, or annual returns depending on their turnover and scheme.

The GSTN portal provides tools for invoice matching, ITC claims, and refund processing,
ensuring seamless administration. Non-compliance, such as delayed filings or incorrect
ITC claims, attracts penalties.
The GST Council plays a pivotal role in policy-making, resolving disputes, and ensuring
uniformity across states. Regular audits and anti-evasion measures, such as e-way bills
for goods transportation, strengthen the system. Over time, GST has evolved with
simplifications like the QRMP (Quarterly Return Monthly Payment) scheme for small
taxpayers.
6 Impact and Future of GST
Since its inception, GST has significantly impacted India’s economy. It has increased tax
collections, with monthly GST revenue averaging over 1.5 lakh crore in 2025, reflecting
robust economic activity. The removal of inter-state barriers has boosted logistics and
e-commerce, fostering a competitive market.
Looking ahead, the GST system is expected to evolve with further simplifications, such as
a potential reduction in tax slabs or inclusion of currently exempt sectors like petroleum
and real estate. Technological advancements, including AI-driven analytics on the GSTN,
aim to enhance compliance and reduce fraud. As India continues to refine GST, it remains
a cornerstone of economic reform, aligning with global best practices in indirect taxation.
