Top 5 States Drive Over 40% of GST Revenue in H1 FY26 — Implications & Insights with Trakintax

When it comes to India’s GST collections, a small group of states are contributing a disproportionately large share. In the first half of FY26 (April–September 2025), Maharashtra, Karnataka, Gujarat, Tamil Nadu and Haryana together accounted for more than 40% of India’s GST revenues.

Why does this matter? What does it reveal about regional economics, and how should businesses and policy makers respond? Below, I break it down in clear language, with key takeaways for business owners, state governments, and general readers.

GST Revenue Snapshot: States vs Rest

Collection Overview

State / Region Average Monthly Revenue (₹ Crore) Notes / Economic Strengths
Maharashtra ₹31,830 Industrial & financial hub
Karnataka ₹14,532 Strong services & IT sector
Gujarat ₹11,833 Diversified trade & industry
Tamil Nadu — (included in top 5) Manufacturing, autos, exports
Haryana Proximity to Delhi / industrial
Combined (Top 5 States)
Other states (UP, Delhi, WB, Telangana, Odisha)
> 40% of total GST revenue
₹5,000–₹10,000 average / mo.
High economic base
Growing consumption engines

Takeaway: The economic might and industrial diversity of top states mean they dominate tax contributions. States with weaker industrial bases still contribute, but on a smaller scale.

Why These 5 States Lead in GST Collections

Here are key factors driving their dominance:

  • 1. Strong industrial base & exporter orientation: Manufacturing, chemicals, automotives, pharmaceuticals, textiles, etc.
  • 2. Robust services economy: IT, finance, logistics, export services.
  • 3. Higher consumption & urbanization: More high-value purchases, more taxable goods used.
  • 4. Better tax administration & compliance: Well-developed systems and tax infrastructure facilitate higher reporting.

Because these states have diversified economies, they benefit both from goods taxes and service taxes—two legs of GST revenue.

Risks & Challenges for Revenue Dependence

While dominating GST collections is powerful, it also comes with vulnerabilities:

  • 1. State revenue risk: Overreliance might hurt states whose growth slows.
  • 2. Economic shocks: A downturn in industry or services in these states could disproportionately affect national collections.
  • 3. Regional inequality: Other states may lag in development if investment and infrastructure skew toward “big tax states.”
  • 4. Policy complacency: States with high revenue might neglect efficiency improvements, assuming inflow will continue.

Trakintax advises business and government clients to monitor collection trends and not take past performance for granted.

Implications for Businesses & Investors

Knowing which states drive GST collections is useful for business strategy:

  • 1. Expansion decisions If you're planning expansion, states with high GST inflows likely reflect greater economic activity, better infrastructure, and better market demand.
  • 2. Tax and Compliance focus Businesses in these states should remain especially careful about compliance enforcement, audits, and policy changes—because they’re under heavier scrutiny.
  • 3. Supply chain & logistics planning You might benefit from locating your operations nearer to these high collection states—lower transit costs, closer to demand hubs.
  • 4. Diversification strategy If your business is concentrated in low-collection states, consider creating distribution or service arms in high collection states to tap demand.

What States Outside Top 5 Need to Do

  • 1. Improve industrial & infrastructure investment: To draw industries that pay large taxes.
  • 2. Focus on service sector growth: Services lend higher margins per output, boosting revenues.
  • 3. Raise compliance awareness: Encourage small and medium enterprises to register and report taxes properly.
  • 4. Optimize logistics & supply chains: Lower cost of doing business to attract investment.
