How to approach

Introduce GST along with its constitutional backing and scope of taxes subsumed. Analyse the core structural transformations ushered in by GST, highlight the ongoing bottlenecks and federal issues, and conclude with recommendations for rationalising rates and broadening the tax base.

377 words

Introduction

Enacted via the 101st Constitutional Amendment Act, 2016, the Goods and Services Tax (GST) subsumed 17 indirect taxes—notably central excise, service tax, and state VAT—along with 13 cesses into a single unified architecture. By creating a unified national market and generating robust monthly revenues exceeding ₹1.84 lakh crore, GST has structurally overhauled India’s indirect tax regime.

Fundamental Transformations Brought by GST

GST represents a paradigm shift from production-based origin taxation to destination-based consumption taxation, bringing major structural reforms:

  • Elimination of Cascading Effect: By instituting a seamless Input Tax Credit (ITC) mechanism across the entire value chain from manufacturer to consumer, GST eliminates 'tax on tax', thereby reducing production costs and enhancing domestic manufacturing competitiveness.
  • Institutionalising Cooperative Federalism: The creation of the GST Council under Article 279A established an institutional platform where the Centre and States pool fiscal sovereignty to make consensus-based tax decisions on rates, exemptions, and thresholds.
  • Formalisation and Tech-Driven Compliance: Backed by the robust digital backbone of the Goods and Services Tax Network (GSTN), mandatory e-invoicing, e-Way bills, and automated return matching have curbed tax evasion and expanded the active taxpayer base from 65 lakh in 2017 to over 1.5 crore.
  • Logistical Efficiency: The dismantling of interstate check posts and border barriers drastically cut turnaround times for freight transport, reducing logistics costs across the nation.

Lingering Challenges and Structural Bottlenecks

Despite significant successes, several operational and structural impediments prevent GST from realizing its full efficiency:

  • Exclusion of High-Revenue Sectors: Major revenue contributors such as crude oil, petrol, diesel, aviation turbine fuel, natural gas, and potable alcohol remain outside GST, fragmenting the tax base and breaking continuous ITC chains.
  • Complex Multi-Tier Slabs: The current multi-tiered rate structure (0%, 5%, 12%, 18%, and 28%) along with various cesses causes classification disputes and generates an inverted duty structure in sectors like textiles and footwear.
  • Federal and Revenue Frictions: Tensions persist regarding state fiscal autonomy, delays in settling Integrated GST (IGST), and the end of statutory compensation cess mechanisms for revenue shortfalls.

Conclusion

GST has definitively achieved its mandate of 'One Nation, One Market' and significantly strengthened tax buoyancy. Going forward, reforms must concentrate on three-tier rate rationalisation, reducing compliance burdens for small enterprises, and progressively bringing excluded energy products under the GST net to unleash its full macroeconomic potential.

Key facts to remember

Frequently asked questions

Why are petroleum products currently excluded from GST?

Petroleum products generate substantial revenues for both Union and State governments through excise duties and VAT. States resisted immediate inclusion to preserve fiscal autonomy, though Article 279A(5) allows the GST Council to include them at a future date.
