GST 2.0: An Analytical Take on India’s Bold Tax Overhaul

India is weighing its most significant tax reform since 2017: a shift from multiple GST slabs to a simpler, two‑rate structure aimed at lowering consumer prices, reducing compliance friction, and lifting growth. This article synthesizes the proposed design, fiscal math, and macro implications using credible sources—so investors and operators can separate signal from noise.

1) What’s on the Table: From Many Slabs to Two

The working proposal simplifies the rate structure to 5% and 18% for most goods and services, while keeping a higher rate for luxury/sin categories (reported near 40%). Timelines under discussion point to implementation around the festive season if consensus is reached by the GST Council.

• Policy intent: Price relief for households, lower compliance for MSMEs, fewer classification disputes.
• Mechanics: Two principal slabs (5%/18%); special treatment persists for demerit goods.
• Governance: Requires GST Council agreement; state buy‑in is pivotal.

2) The Fiscal Math: Short‑Term Cost, Medium‑Term Payoff?

Independent estimates peg the near‑term revenue impact at roughly ₹1.6 lakh crore (~$20bn), or about 0.3% of GDP. Some houses view this as manageable if accompanied by stronger compliance and widening of the base. Concurrent personal tax tweaks have been framed as an aggregate demand booster (a combined impulse of ~0.7–0.8% of GDP in some estimates).

3) Growth & Consumption: Quantifying the Uplift

Rate simplification plus targeted cuts can lift measured GDP via consumption and formalization. Street and sell‑side workups suggest a 0.5–0.7 percentage point boost to annual growth in the first year, conditional on implementation quality and coverage.

• Macro impulse: Studies cite a ~0.6 pp GDP lift from cheaper goods/services and improved pass‑through.
• Demand delta: Analysts model ~₹2.4 lakh crore incremental consumption as prices reset lower and sentiment improves.
• External shield: Domestic demand support helps buffer export‑side risks amid global tariff noise.

4) Sector Lens: Who Stands to Benefit?

The equity market has treated reforms as pro‑consumption. Under plausible re‑rating paths, the following pockets look most levered to a two‑slab regime:

5) Execution Risks & Political Economy

• State revenues: Compensation and formula design must address states reliant on higher slabs.
• ITC integrity: Preserving input tax credit mechanics is crucial to avoid cascading.
• Transition costs: Re‑tagging HS codes, repricing, and ERP changes can temporarily disrupt supply.
• Inflation optics: If pass‑through is uneven, measured disinflation could lag even as firms re‑optimize pricing.

6) Wealth North View: How to Position

• Near term: Expect policy‑headline volatility; accumulate quality consumer & financial names on weakness where earnings elasticity is credible.
• Medium term: Favor firms with clean ITC chains, low litigation risk, and operating leverage to price/mix tailwinds.
• Risk controls: Track GST Council outcomes, state negotiations, and the realized revenue trajectory in FY26.
