GST at Nine: India's Indirect Tax Revolution

Introduction

The Goods and Services Tax (GST) completed nine years since its launch on July 1, 2017, representing India's most significant post-Independence indirect tax reform. The 101st Constitutional Amendment Act, 2016 introduced this unified, destination-based consumption tax, subsuming multiple central and state-level indirect taxes.

4. Strengthening Cooperative Federalism

• GST Council: Created under Article 279A as joint forum for Centre and States
• Enables consensus-based decision making on tax rates, exemptions, and threshold limits
• Regular reviews and course corrections addressing emerging challenges
• Represents innovative model of cooperative federalism in tax governance

5. Digital Transformation of Tax Administration

• GST Network (GSTN): Common digital infrastructure for all stakeholders
• E-invoicing: Mandatory for B2B transactions, reducing tax evasion
• ICEGATE: Electronic clearance of imports and exports

• 40% rate: Luxury and sin goods (introduced in GST 2.0)

Dual Structure

Destination-Based Consumption Tax

• GST is collected on value addition at each stage

• Replaced origin-based taxation model

GST 2.0: Next-Generation Reforms

The 56th GST Council meeting approved Next-Generation reforms effective 22nd September 2025:

Challenges in Current GST Framework

1. Exclusion of Key Items

• Five petroleum products: Crude oil, petrol, diesel, ATF, natural gas
• Impact: Limits seamless ITC, creates tax cascading
• States heavily depend on revenue from these items
• Political sensitivity阻碍 comprehensive inclusion

2. Rate and Classification Disputes

• Multiple interpretational issues in product classification
• Sector-specific exemptions create complications
• GST Council decisions sometimes contested
• Litigations increase compliance costs

3. GST Appellate Tribunal (GSTAT) Operationalisation

• Delays in appointments and infrastructure
• Prolonged litigation affecting business certainty
• Need for faster resolution mechanisms

4. Compliance Burden for Small Businesses

• Frequent notifications and amendments
• Return filing requirements (GSTR-1, GSTR-3B, GSTR-2)
• Reconciliation mismatches between forms
• Keeping pace with changing procedural rules

5. Inverted Duty Structure

• Input taxes higher than output taxes in some sectors
• Accumulated ITC leading to refund claims
• Working capital stress
• Liquidity pressure on businesses

6. Centre-State Revenue Concerns

• Compensation cess debates
• Revenue protection mechanisms
• Divergence in fiscal interests
• Impact on cooperative federalism

Suggested Reforms for Strengthening GST

1. Phased Inclusion of Excluded Items

• Petroleum products: Begin with natural gas and ATF
• Revenue-neutral rates with compensation safeguards
• Alcohol: Requires constitutional amendment
• Wider political consensus essential

2. Further Rate Rationalisation

• Review remaining exemptions
• Address sector-specific inverted duties
• Reduce classification disputes
• Move towards ideal two-slab structure

3. Faster Refund Processing

• Article 269A: Levy and collection of GST on inter-state supplies
• Article 279A: Constitution of GST Council
• GST (Compensation to States) Act, 2017: Compensation mechanism

Significance for Viksit Bharat

GST aligns with the vision of Viksit Bharat through:

• Creating common national market
• Formalising the economy
• Improving tax-GDP ratio
• Reducing tax arbitrage
• Enabling data-driven governance
• Strengthening cooperative federalism

Conclusion

Nine years of GST has transformed India's indirect tax landscape, creating a unified market, expanding formalisation, and strengthening federal tax governance. However, the unfinished agenda—inclusive of petroleum/alcohol inclusion, complete rate rationalisation, and faster dispute resolution—remains crucial for achieving a simpler, more transparent, and growth-oriented GST system.
