Goods and Services Tax (GST)

The Goods and Services Tax (GST) is a comprehensive indirect tax reform that replaced a complex web of central and state taxes in India. Enacted by the GST Act, 2017, and implemented from 1st July 2017, GST is a destination-based, multi-stage value-added tax on the supply of goods and services. It was designed to simplify the tax structure, eliminate the cascading effect, and create a unified national market.The tax would accrue to the taxing authority which has jurisdiction over the place of consumption which is also termed as place of supply

Why GST Was Needed ?

Before GST, India’s indirect tax system suffered from:

  • Multiplicity of taxes and duties.
  • Cascading (tax on tax) effects.
  • Steep inter-state variations.
  • Inefficient exemptions and too many tax slabs.
  • Widespread evasion.

Aim

GST aimed to:

  • Simplify the tax structure.
  • Create a common national market.
  • Boost investment and growth.
  • Reduce production costs and improve export competitiveness.
  • Enhance transparency and curb black money.

Key Features

  • Comprehensive: Combines many central and state indirect taxes.
  • Multi-stage: Levied at every stage of value addition, but input tax credit ensures only the final consumer bears the tax.
  • Destination-based: Tax collected where goods/services are consumed, not where produced.
    • Example: If goods are made in Gujarat and sold in Telangana, they are taxed in Telangana where the consumer pays it.
  • Dual GST:Dual GST means that GST will be levied simultaneously by Center and State Governments. However, when the transaction is between states, there will be Integrated GST (CGST + SGST), which will be collected by the Central Government and then the SGST component paid to the State Government where the goods or services have been consumed.

Structure of GST

Different Types of GST Tax in India are: 

  • CGST:CGST stands for Central Goods and Services Tax. It is an indirect tax levied by the central government on intrastate supplies of goods and services, as outlined in the CGST Act of 2017.Under the GST framework, CGST applies to transactions within a single state. It ensures that the central government receives its share of tax revenue for these intrastate supplies.
  • SGST/UTGST:SGST means State Goods and Services Tax, one of the three categories under Goods and Services Tax (CGST, IGST and SGST).It is a tax levied on Intra State supplies of both goods and services by the State Government and will be governed by the State Goods and Services Tax Act 2016.SGST applies to transactions involving the sale of goods and services within the same state. For instance, if a clothing store in Gujarat sells a dress to a customer also in Gujarat, SGST would be applicable.In union territories like Chandigarh, Puducherry, and the Andaman and Nicobar Islands, SGST is replaced by Union Territory Goods and Services Tax (UTGST).
  • IGST:IGST stands for Integrated Goods and Services Tax.It is governed by the IGST Act.It is a type of indirect tax that is levied on the interstate supply of goods and services in India. IGST is collected by the central government, and the revenue is shared between the central and state governments.
  • Centre levies and administers CGST & IGST while respective states will levy and administer SGST.

GST Rates in India

  • Goods and services in India fall under different GST slabs: 0% for essential items, 5% for basic necessities, 12% for standard goods, 18% for most consumer products, and 28% for luxury and sin goods.
  • There are a few lesser-used GST rates such as 3% and 0.25%.

GST 2.0 Reforms

  • India’s GST 2.0 marks a major reform of the Goods and Services Tax system. Approved at the 56th GST Council meeting, it will come into effect on 22 September 2025.
  • The new regime replaces the earlier four-tier GST structure of 5%, 12%, 18%, and 28% with a simplified two-rate system — 5% (merit rate) for essential goods and 18% (standard rate) for most other items. In addition, a 40% demerit rate has been introduced for luxury items, sin goods, and demerit products such as tobacco, pan masala, and premium consumer goods.

List of taxes subsumed under GST in India

Central Taxes Subsumed

  • Central Excise Duty
  • Service Tax
  • Additional Excise Duties (Textiles and Textile Products, Goods of Special Importance, etc.)
  • Additional Customs Duty (Countervailing Duty – CVD)
  • Special Additional Duty of Customs (SAD)
  • Central Surcharges and Cesses (related to supply of goods and services)

State Taxes Subsumed

  • Value Added Tax (VAT) / Sales Tax
  • Entertainment Tax (other than the tax levied by local bodies)
  • Luxury Tax
  • Entry Tax (All forms of Entry tax, Octroi, etc.)
  • Purchase Tax

The GST Council shall make recommendations to the Union and States on the taxes, cesses and surcharges levied by the Centre, the States and the local bodies which may be subsumed in the GST.

Benefits of GST

For Business and Industry

  • Easy Compliance:
    • A unified IT system enables online registration, returns, and payments, making compliance transparent and simpler. Earlier, businesses had to file separate returns for VAT and Excise; now only a single GST return is needed.
  • Uniform Tax Rates:
    • GST has standardized indirect tax rates nationwide, replacing multiple excise and VAT rates with just a few slabs. This reduces compliance costs and promotes ease of doing business.
  • Removal of Cascading:
    • Seamless input tax credit across the value chain has eliminated the tax-on-tax effect, lowering costs and improving competitiveness.
  • Boost to Exports:
    • Subsuming state and central taxes and enabling full input tax credit has reduced the cost of domestic production, making Indian exports more competitive globally.

For Central and State Governments

  • Cooperative Federalism:
    • GST decisions are taken jointly by the Centre and States via the GST Council, strengthening cooperative federalism.
  • Simplified Administration:
    • Multiple indirect taxes have been merged into one, backed by a robust IT system. Eliminating inter-state check posts has further streamlined compliance.
  • Better Compliance and Less Corruption:
    • Invoice matching for input tax credit creates a self-policing system that deters evasion.
  • Wider Tax Base:
    • Many previously unregistered businesses have joined the GST network, increasing tax revenue.
  • Higher Revenue Efficiency:
    • Collection costs have fallen, improving overall revenue performance.

For Consumers

  • Transparent and Single Tax:
    • Under GST, the consumer pays one tax from manufacturer to retailer, removing the hidden layers of taxes that existed earlier.
  • Lower Tax Burden:
    • Efficiency gains, reduced leakage, and elimination of cascading have brought down overall tax on most goods and services.

Formalization of the Economy

  • The GST system encourages small enterprises to register, strengthening economic data collection and enhancing tax revenue generation. This shift toward formalization has fostered a more transparent, accountable, and robust business ecosystem.

Drawbacks of GST on the Indian Economy

  • Complex Compliance Requirements
    • Despite simplification compared to the earlier system, GST compliance remains challenging for many small businesses.
    • Return filing requirements, and reconciliations have increased the compliance burden, especially on micro, small, and medium enterprises (MSMEs).
  • Multiple Tax Slabs
    • Unlike many countries with a single GST rate, India has five main slabs (0%, 5%, 12%, 18%, 28%) plus cesses.
    • This complex rate structure has led to classification disputes and confusion among taxpayers.
  • Impact on Informal Sector
    • GST has compelled many informal businesses to register and comply, which increases their costs.
    • While this formalization improves transparency, it has also disrupted unorganised sectors and caused job losses in the short run.

While the Goods and Services Tax (GST) has significantly modernised India’s indirect tax framework by improving transparency and broadening the tax base, its drawbacks—such as complex compliance, multiple tax rates, and pressure on small businesses—highlight the need for continuous reforms. Streamlining procedures, simplifying rates, and strengthening digital infrastructure will be essential to ensure GST evolves into a truly efficient, equitable, and business-friendly tax system.
