9 Years of GST : India's Tax Revolution — What Worked, What Didn't, and What's Next
On the night of June 30, 2017, India did something extraordinary. Lawmakers gathered inside Parliament’s Central Hall — not for a debate, but for a historic midnight launch of a tax system that would rewrite how an entire nation of 140 crore people buys, sells, and pays taxes. That system was the Goods and Services Tax (GST).
Nine years later, the dust has largely settled. And the picture that emerges is neither the utopia some promised, nor the disaster others feared — it’s a complex, evolving story of a nation learning to govern itself differently.
Why India Needed a Tax Overhaul in the First Place
Before GST, buying a product in India was deceptively expensive — not because the product cost more, but because taxes piled on top of taxes at every step of the supply chain.
Imagine a manufacturer in Gujarat selling goods to a distributor in Maharashtra, who then sold to a retailer in Tamil Nadu. Each state had its own tax. The Centre had its own. Excise duty, VAT, service tax, entry tax, octroi — the list was long and the paperwork longer. By the time a product reached your hands, it had been taxed multiple times on the same value. This “cascading effect” inflated costs silently.
GST was designed to end exactly this. One tax. One rate for one category of goods. One portal. One market from Kashmir to Kanyakumari.
What GST Actually Achieved in 9 Years
1. A Formal Economy — Numbers That Tell the Story
One of GST’s biggest, quietest victories has been pulling businesses into the formal economy.
Under the old VAT and service tax system, only about 67.80 lakh unique businesses were registered. Today, that number stands at over 1.65 crore registered taxpayers — more than double. Many of these are small traders and micro-entrepreneurs who voluntarily joined the system because being formal now actually benefits them: access to credit, the ability to claim input tax credit, and the credibility to supply larger companies.
This formalisation matters beyond tax collection. A registered business is a visible business — one that can access bank loans, government schemes, and supply chains that were previously out of reach.
2. Revenue Growth That Defied Expectations
Critics once doubted whether a unified tax system would generate enough revenue. The numbers have answered that clearly.
In August 2017 — the first month GST collections were recorded — the government collected about ₹94,603 crore. By April 2026, that monthly figure had surged to a record ₹2.43 lakh crore in a single month. The average monthly collection for FY 2025–26 now hovers between ₹1.80 to ₹1.85 lakh crore, and the total annual gross GST collection for FY 2025–26 reached an all-time high of ₹22.27 lakh crore.
This isn’t just inflation-driven growth. It reflects wider compliance, better technology-based enforcement, and a genuinely expanding formal economy.
3. Cooperative Federalism — A Rare Political Achievement
India is a federation of states with vastly different political parties in power. Getting them all to agree on anything — let alone share taxing powers — is no small feat.
The GST Council, which brings together the Union Finance Minister and finance ministers of all states, has met 56 times since its formation. Remarkably, almost every decision has been made by consensus. Only once — regarding taxation on lotteries in the 38th Council meeting (December 2019) — did the Council have to put a matter to vote.
This level of cooperative decision-making between the Centre and states, cutting across party lines, is genuinely rare in Indian governance. It’s a structural achievement that often goes unappreciated.
4. Technology at the Heart of Compliance
For years, one of the biggest criticisms of GST was its multi-slab structure: 0%, 5%, 12%, 18%, and 28%, with an additional cess on luxury goods. This complexity confused businesses, created classification disputes, and made compliance harder.
In September 2025, the GST Council finally addressed this. The rate structure was overhauled — reduced from five slabs to effectively three working slabs: 5% (merit goods), 18% (standard), and 40% (luxury and demerit goods).
The practical impact was immediate and tangible:
On food and daily essentials:
- Everyday items like UHT milk, paneer (pre-packaged), pizza bread, and chapati were moved to the nil tax bracket
- Products like butter, cheese, condensed milk, and dry fruits were reduced from 12% to 5%
On automobiles:
- Tax on two-wheelers above 350cc and small cars was cut from 28% to 18%
- The resulting price drops on popular models like Honda Activa, Hero Splendor, and Bajaj Pulsar ranged from ₹5,000 to ₹24,000 per vehicle
- In October 2025 alone, two-wheeler retail sales hit 31.50 lakh units — a 52% year-on-year jump
- Passenger car sales that same month reached an all-time high of 5.57 lakh units, up 40.5% year-on-year
Consumer behaviour data from April 2025 to June 2026 confirms what the numbers suggest — when taxes fall meaningfully, people spend more. Affordability drives demand, and demand drives growth.
What GST Has Not Fixed — The Honest Assessment
A balanced review requires looking at what remains unresolved
Petroleum, Liquor, Electricity — The Glaring Omissions
When GST was implemented, several major revenue-generating categories were kept outside its scope — most notably petroleum products, natural gas, liquor for human consumption, and electricity.
The reason was political and fiscal. States like Maharashtra collect up to 40% sales tax on petroleum products, while others like Andaman & Nicobar levy as little as 6%. Petroleum and liquor together accounted for nearly 40% of all indirect tax revenue under the old VAT regime. States were understandably reluctant to surrender that fiscal independence to a unified rate.
Nine years later, this exclusion still creates distortions. Fuel costs affect the price of almost every good transported across the country. Keeping it outside GST means manufacturers cannot claim input tax credit on fuel expenses — a cost that ultimately gets passed to consumers.
Input Tax Credit — Seamless in Theory, Messy in Practice
The promise of GST was that input tax credit (ITC) — the ability to offset tax paid on purchases against tax collected on sales — would flow seamlessly across the supply chain. In practice, it hasn’t always worked that way.
Businesses, particularly smaller ones, frequently face ITC mismatches, blocked credits, and disputes arising from supplier non-compliance. If your supplier doesn’t file their GST returns correctly, your ITC claim gets stuck — even if you paid the tax. This asymmetry between what the law promises and what businesses experience remains a significant pain point.
Dispute Resolution — Still a Work in Progress
GST disputes — whether over classification, rate applicability, or ITC denial — continue to pile up. The formal dispute resolution mechanism, including GST Appellate Tribunals, took years to become operational, leaving businesses in prolonged uncertainty. While progress has been made, the system still needs to become faster, more predictable, and less litigious.
Inverted Duty Structure — Partially Resolved
An inverted duty structure occurs when the tax rate on inputs is higher than the tax rate on the final product — resulting in manufacturers accumulating ITC they cannot use. The 2025 rate rationalisation addressed several such cases, but the issue has not been fully resolved across all sectors.
What's Coming Next — The Road Ahead
The GST Council’s next meeting is expected in mid-July 2026 in Kolkata, with key agenda items likely including:
- Further resolution of inverted duty structures
- Simplification of the ITC reconciliation process
- Strengthening of the dispute resolution framework
- Deliberations on bringing petroleum under GST — a long-pending item that states have resisted but economists have advocated for
The broader context matters too. India has set an ambitious target: Viksit Bharat by 2047 — a fully developed economy within the next two decades. GST is a foundational pillar of that vision. A cleaner, simpler, more dispute-free GST will directly support higher investment, better ease of doing business, and stronger domestic manufacturing.
What This Means for Your Business
Whether you’re a small trader, a mid-size manufacturer, or a large enterprise, the evolving GST landscape has direct implications:
- Rate changes affect your pricing and margins — staying updated on GST Council decisions is not optional
- ITC reconciliation discipline is critical — ensure your vendors are filing returns on time; their lapses affect your cash flows
- Dispute preparedness matters — with Tribunals now functional, having proper documentation from Day 1 protects you
- Voluntary registration is worth considering — even if you’re below the threshold, being in the GST system opens doors to credit, larger contracts, and government tenders
Final Thoughts
Nine years of GST is nine years of learning — for taxpayers, for tax administrators, and for policymakers. The system is genuinely better than what it replaced. Revenue is up, compliance is wider, and the single national market is real.
But the job isn’t done. Petroleum, ITC friction, and slow dispute resolution remain unfinished business. The upcoming GST Council meeting in July 2026 will signal how seriously these are being taken.
