Why This Editorial Matters
On 1 July 2026, the Goods and Services Tax completes nine years. The anniversary arrives at an inflection point. Negative business sentiment, once the dominant note in GST commentary, has fallen sharply. The registered taxpayer base has swelled from roughly 60 lakh at rollout in 2017 to over 1.5 crore today. And the much-debated “GST 2.0” rate rationalisation, effective from September 2025, has collapsed the old four-slab maze into a leaner structure built around a 5% merit rate, an 18% standard rate, and a 40% rate for sin and luxury goods.
For a UPSC aspirant, this is not merely an economy story. GST sits at the precise intersection of GS3 (Indian economy, mobilisation of resources, taxation) and GS2 (federalism, devolution, Centre-State financial relations). The challenge in the exam hall is to move past celebratory data and interrogate the two questions that genuinely divide policymakers: is GST 2.0 revenue-neutral, and is the GST Council a federal partnership or a managed consensus?
The Argument: Formalisation Has Worked, the Federal Bargain Is Strained
The Mint commentary’s core claim is twofold. First, GST has succeeded as a formalisation engine. Second, that success now rests on resolving design tensions that GST 2.0 eases but does not eliminate.
What GST Actually Is (Get the Definition Exam-Perfect)
GST is a destination-based, multi-stage, value-added tax on the supply of goods and services. Three descriptors carry full marks if used precisely:
- Destination-based: tax accrues to the state where goods or services are consumed, not produced. This reshaped Centre-State revenue geography, favouring consuming states.
- Multi-stage: levied at every stage of the supply chain, from manufacture to final sale.
- Value-added: through Input Tax Credit (ITC), tax is effectively paid only on the value added at each stage, removing the cascading “tax on tax” that plagued the pre-GST system of VAT, excise, service tax and a host of cesses.
GST was brought in by the 101st Constitutional Amendment Act, 2016, which conferred simultaneous (concurrent) taxing power on Parliament and State Legislatures and inserted Article 246A and Article 279A.
The Formalisation Evidence
The headline metric is the taxpayer base: from about 60 lakh registrants in 2017 to over 1.5 crore in 2026. This matters because each new registrant is, in principle, a business entering the formal credit chain, generating an audit trail, and becoming eligible for institutional finance. Reinforcing tools include:
- Input Tax Credit (ITC): the self-policing mechanism. A buyer claims credit only if the seller has paid tax, which incentivises both parties to come on record.
- E-way bills: mandatory electronic documentation for the movement of goods above a threshold value, sharply reducing the under-invoicing and “kachcha bill” leakage of the old regime.
- Buoyant collections: record monthly gross collections in the range of around Rs 1.8 to 2 lakh crore, signalling improved compliance and a wider net rather than merely higher rates.
How to Think About It: The Revenue-Neutrality Tension
Here is the analytical hinge most aspirants miss. When GST was designed, the implicit benchmark was the Revenue Neutral Rate (RNR), the single rate at which government revenue would be unchanged relative to the taxes GST replaced. The original RNR estimates clustered around 15 to 15.5%.
GST 2.0 cuts rates on a large basket of mass-consumption goods. That is excellent for consumers and for taming inflation, but it raises an unavoidable question: if the effective average rate falls below the revenue-neutral level, where does the lost revenue come from?
The standard counter is the Laffer-style buoyancy argument: lower rates plus simpler compliance widen the base and improve collections, so revenue need not fall. There is genuine evidence for this in the rising taxpayer count and collections. But the magnitude and durability of that offset are uncertain, and this is exactly the kind of “it depends” judgement a top answer should flag rather than assert.
The Federalism Dimension (The GS2 Core)
This is where GST graduates from an economy topic to a polity topic.
The GST Council in One Diagram (In Words)
Picture a single table under Article 279A:
- Chair: the Union Finance Minister.
- Members: the Union Minister of State for Finance, plus a minister nominated by each state government.
- Voting weight: the Centre carries one-third of the weighted votes; all states together carry two-thirds.
- Decision threshold: a resolution passes only with a three-fourths majority of the weighted votes present and voting.
The arithmetic is deliberate. The Centre alone cannot pass a measure (one-third is below three-fourths), and the states alone cannot either. Every decision requires a coalition straddling the Centre-State line. On paper, this is cooperative federalism in its purest institutional form.
The Counter-View: Consensus or Coercion?
Critics, including several state finance ministers, argue the reality is more centralised than the design suggests. Two grievances recur:
- Loss of autonomy: states surrendered their constitutional power to independently levy major indirect taxes. They can no longer use tax rates as a counter-cyclical or developmental lever.
- The compensation cliff: the GST Compensation Cess, which guaranteed states a 14% annual revenue growth for five years (later extended to service the COVID-era borrowing), has wound down. With that safety net gone, deep GST 2.0 rate cuts land directly on state revenues, and states fear a structural squeeze on their fiscal space without a successor guarantee.
The honest verdict: the Council has functioned largely by consensus for nine years, but the few divisive votes and the compensation dispute reveal that the federal bargain holds best when revenues are buoyant and frays when they are not.
Way Forward
A balanced answer should propose institutional fixes, not slogans:
- A transparent revenue-neutral framework: publish the data and methodology behind rate decisions so cuts are evidently affordable, not politically timed.
- Strengthen the Council as a deliberative body: lean on consensus and structured dispute-resolution rather than letting weighted voting decide contested questions.
- A post-compensation stabilisation mechanism: consider a fiscal stabilisation fund or a formula-based assurance to cushion states through revenue shocks.
- Finish the plumbing: speed up refunds (a recurring exporter and MSME pain point), rationalise audits, and make the GST Appellate Tribunal fully operational to clear the litigation backlog.
PYQ Linkage
- 2019 (GS3): “Enumerate the indirect taxes which have been subsumed in the Goods and Services Tax (GST) in India. Also, comment on the revenue implications of the GST introduced in India since July 2017.” This editorial directly updates that answer with nine years of collections and the GST 2.0 reform.
- 2017 (GS3): “Explain the salient features of the Constitution (One Hundred and First Amendment) Act, 2016. Do you think it is efficacious enough to remove cascading effect of taxes and provide for common national market for goods and services?” Use the ITC and destination-based arguments above.
- Prelims hook: Article 279A (GST Council), Article 246A (concurrent taxing power), the one-third / two-thirds voting weight, and the three-fourths majority rule are high-frequency factual targets.
Facts Corner
- Rollout: 1 July 2017, celebrated annually as GST Day; ninth anniversary on 1 July 2026.

- GST Council: Article 279A; chaired by Union FM; Centre one-third and states two-thirds of weighted votes; decisions need a three-fourths majority.
- GST 2.0 (effective 22 September 2025): rationalised slabs to a 5% merit rate, an 18% standard rate, and a 40% demerit rate for sin and luxury goods (alongside the 0% exemption).
- Taxpayer base: grown from roughly 60 lakh (2017) to over 1.5 crore (2026).
- Collections: record monthly gross GST in the range of around Rs 1.8 to 2 lakh crore.
