GST Rate Reductions in India: Boosting GDP Growth, Strengthening Defense Procurement, and Enhancing MSME Cash Flows – An Integrated Case Study

 GST Rate Reductions in India: Boosting GDP Growth, Strengthening Defense Procurement, and Enhancing MSME Cash Flows – An Integrated Case Study 

Abstract

India’s Goods and Services Tax (GST) Council introduced landmark rate cuts on 22 September 2025, rationalizing the structure into primarily 5% and 18% slabs. These reforms include dramatic reductions on automobiles, cement, medical devices, consumer durables, and strategic defence materials. Economists estimate a 60-basis-point uplift in GDP, driven by increased consumption, reduced inflationary pressures, and improved corporate margins.
Further, by lowering GST to 0–5% on key defence items, the reforms generate annual procurement savings of ₹15,000–₹25,000 crore, strengthening indigenisation under “Atmanirbhar Bharat.”
MSMEs—responsible for nearly 30% of GDP and 45% of exports—experience significant liquidity improvements through faster refunds, simplified input tax credit (ITC) flows, and reduced working capital blockages.

This case study evaluates macroeconomic, sectoral, and defence-specific impacts, using secondary data from RBI, GST Council reports, industry analyses, econometric forecasts, and post-2025 policy reviews. The findings show that GST rationalisation harmonises prices, enhances competitiveness, and supports India’s trajectory toward 7%+ sustained GDP growth.

1. Introduction

India’s taxation landscape underwent one of its most consequential reforms since 2017 as the GST Council approved sweeping rate reductions on 22 September 2025. Motivated by slowing consumption due to global trade tensions, rising US tariffs, and tight household budgets, the Council simplified the GST structure by reducing the number of slabs and lowering rates on essential consumption and production categories.

Key features of the 2025 reforms include:

• Consolidation into 5% and 18% slabs for most goods.
• Reduction of GST on automobiles (28% to 18%), cement (28% to 18%), and healthcare devices (12% to 5%).
• Zero or 5% GST on defence items including drones, UAVs, batteries, and certain missile components.
• Streamlined refund mechanisms, especially for MSME exporters, ensuring disbursal within 10 days.
• Expanded ITC (input tax credit) eligibility and simplified compliance portals.

These reforms sought to counter slowing private consumption—constituting ~60% of India’s GDP—and stimulate demand in labour-intensive and manufacturing-led sectors. The government acknowledged a potential ₹48,000 crore annual revenue shortfall, but prioritised long-term consumption and macroeconomic benefits.

Economists from leading institutions estimate that GST cuts could raise GDP growth for FY 2025–26 to 6.6%, higher than the RBI’s 6.5% baseline projection. Inflation is projected to decline by 100 basis points, creating further room for consumption expansion.

The reforms also align with strategic priorities: supporting Atmanirbhar Bharat, boosting defence exports, and enabling MSMEs to participate more effectively in formal supply chains.

 

2. Review

2.1 GST and Economic Growth in India

Early literature (2017–2022) on GST implementation highlights mixed impacts:

• Reduction of effective tax incidence in manufacturing (15–18%).
• Short-term disruptions due to compliance burdens and technological unfamiliarity.
• Long-run benefits through the creation of a unified national market.

Studies by RBI, NIPFP, and independent economists confirm that GST rationalisation reduces cascading taxes, enhances market efficiency, and supports consumption-led GDP expansion.

2.2 Sectoral Impacts of GST Reforms

Studies examining GST variations across sectors show:

• Automobiles benefit from lower levies on two-wheelers and small cars, improving affordability.
• Cement and construction exhibit strong multiplier effects, with lower GST reducing housing and infrastructure costs.
• Healthcare experiences positive welfare effects from reduced costs of diagnostics and medical devices.
• Consumer durables and textiles gain through reduced household expenditure, improved export competitiveness, and job creation.

Recent 2025 literature indicates that rate cuts on renewables (from 12% to 5%) improve green energy adoption, with positive externalities.

2.3 GST and Defence Sector Efficiencies

Earlier studies on defence procurement highlight:

• Taxation previously inflated costs of imported spares and indigenous manufacturing inputs.
• Indigenisation under “Make in India” surged, with defence production reaching ₹1.27 lakh crore in FY 2023–24.
• Defence exports rose from ₹4,682 crore in 2017 to ₹23,622 crore in FY 2024–25.

Empirical studies link tax relief to improved procurement efficiency, supply chain resilience, and R&D expansion in strategic technologies such as UAVs.

2.4 GST and MSME Liquidity

Research reveals that GST initially strained MSMEs (2017–2021) due to:

• Blockages in working capital.
• Delays in refund payment cycles.
• High compliance and technology adoption costs.

Post-2024 literature emphasises improvements:

• Better ITC management.
• Faster refunds.
• Rationalised rates reducing cost burdens.
• Simpler compliance frameworks lowering operational costs.

The 2025 reforms are widely viewed as the most MSME-friendly since GST’s inception.

• Indigenous R&D
• Export competitiveness (target: ₹50,000 crore by 2029)

4.2.3 Defence GDP Contribution

India’s defence expenditure (~2% of GDP) lags global peers (recommended: 2.5%).
GST savings narrow this gap through:

• Efficiency-led contributions
• Higher domestic value addition
• Expanded export revenue

 

4.3 Macroeconomic Impact: GDP and Inflation

Economists estimate:

• GDP boost: +0.6 percentage points (60 bps)
• Inflation reduction: −1 percentage point (100 bps)
• Monthly GST collections: ₹1.8–1.95 lakh crore (buoyancy offsets revenue losses)

These macro effects stem from:

• Higher private consumption
• Lower cost of goods
• Improved corporate margins
• Rising capital expenditures

 

4.4 MSME Cash Flow Improvements

The 2025 reforms specifically address MSME liquidity issues.

4.4.1 Faster Refunds

• Refunds processed within 10 days for exporters.
• Working capital release: ₹25,000–₹30,000 crore annually.
• Borrowing dependency decreases; credit health improves.

4.4.2 Improved ITC Flow

• Seamless reconciliation
• Reduced disputes
• Lower production costs
• Higher profit margins

4.4.3 Sectoral Relief

• Textiles, handicrafts, leather, machinery: GST reductions improve cash flow.
• Small units invest more in technology and skilled labour.

4.4.4 Remaining Challenges

• Compliance complexities persist for rural MSMEs.
• Digital literacy limitations hamper ITC optimisation.
• Working capital delays still occur in highly seasonal industries.

5. Discussion

The 2025 GST reforms have multidimensional impacts across India’s economic landscape.

5.1 Consumption-Led Growth

Reducing GST on essential and high-frequency items does two things:

1. Raises disposable income
2. Improves price elasticity of demand

This explains the strong revival in auto, housing, and durable goods demand.

5.2 Defence as a Strategic Multiplier

Unlike civilian sectors where savings marginally enhance profitability, defence savings have strategic multipliers:

• Procurement of additional assets
• Faster modernisation
• Reduced import costs
• Greater self-reliance
• Export expansion

These indirect contributions magnify defence’s share in real GDP growth.

5.3 MSMEs: The Backbone of Employment

By resolving persistent liquidity bottlenecks, GST reforms:

• Lower the cost of doing business
• Increase competitiveness
• Enable scaling through formal credit
• Promote integration into global supply chains

However, MSMEs require:

• Continued digitisation support
• Capacity-building initiatives
• Simplified compliance ecosystem

5.4 Fiscal Trade-Offs

GST rate cuts reduce short-term tax collections by ₹48,000 crore annually, but:

• GST buoyancy offsets losses
• Higher consumption improves direct tax collections
• Broader compliance reduces evasion

Thus, long-term fiscal stability remains intact.

5. Instructor Tips

• Emphasise the link between tax policy → price signals → household behaviour → GDP.
• Encourage students to compare India’s GST structure with global models (EU VAT, ASEAN GST).
• Use the defence discussion to highlight strategic economics, not just taxation.
• Clarify that GST reforms can raise GDP even with a short-term revenue loss due to higher buoyancy.
• Discuss political economy: why rate cuts were introduced in 2025.

 

6. Conclusion

The GST rate rationalisation of September 2025 represents a decisive shift toward a growth-oriented taxation regime. By reducing rates on consumption, manufacturing, healthcare, and defence procurement, India positions itself for:

• Higher GDP growth
• Lower inflation
• Improved household affordability
• Stronger defence capabilities
• Enhanced MSME liquidity

The reforms succeed by combining macroeconomic stimulus with strategic national priorities.

For sustained benefits, policymakers must ensure:

• Full pass-through of tax savings
• Continuous monitoring of inflation trends
• MSME capacity-building
• Integration of defence R&D into broader industrial policy
• Ongoing GST simplification

Overall, the 2025 GST reforms strengthen India’s foundation for achieving 7%+ annual GDP growth while promoting inclusive, sector-wide development.
