GST 2.0: India’s Two Slab Reform (5% & 18%) Explained
India moves to two GST slabs — 5% & 18% (40% for demerit goods). What it means for prices, MSMEs, and growth. Analysis by Kushal Dev Rathi.

India has just executed one of the most consequential tax simplifications since 2017. Following the 56th GST Council meeting, the government has rationalised GST into two principal slabs — 5% and 18% — with a special 40% rate for select demerit/luxury goods. Media briefings indicate the new structure becomes effective from September 22 (per ToI’s report), marking a decisive move toward “GST 2.0.” (The Times of India)
This reform matters for three reasons: simplicity, predictability, and momentum. A cleaner two‑rate system reduces classification disputes, lowers compliance friction for MSMEs, and sends a signal to investors that India is serious about policy clarity — the currency global capital values the most. The government’s pre‑meeting trail (GoM consultations, Finance Minister’s address) shows this was not a surprise swing but a measured, multi‑stakeholder transition. (Business Standard, NDTV Profit)
TL;DR — The change in one glance
Two core GST slabs: 5% & 18%, replacing the earlier multi‑slab complexity; 40% for demerit goods remains.
Go‑live reported for Sept 22 (watch official notifications for item‑wise schedules). (The Times of India)
Objective: simplify compliance, cut disputes, and widen the base via growth and formalisation. (India TV News)
Seven implications that matter (beyond any single asset class)
1) Lower friction, faster decisions
A two‑rate grid collapses thousands of classification edge‑cases. Pricing, ERP mapping, and vendor contracts become cleaner, reducing “tax engineering” conversations that consumed management bandwidth. Expect fewer rate‑fit disputes and speedier supply‑chain decisions. (Council/GoM rationale: simplification & predictability.) (Business Standard, India TV News)
2) MSME compliance relief
Small businesses suffer the most from compliance ambiguity. Fewer slabs mean simpler HSN mapping, cleaner invoicing, and fewer working‑capital shocks from surprise reclassifications. It also improves lender comfort when evaluating MSME cash flows (less volatility from tax disputes).
3) Mild disinflationary bias
Where rates fall (or ambiguity falls), pass‑through pressure builds. Even if nominal MRPs do not drop overnight, clearer slabs reduce embedded compliance costs, nudging prices lower at the margin over a few billing cycles. With the festive quarter ahead, that’s meaningful for sentiment and sales.
4) Formalisation flywheel
India’s tax tech stack (e‑invoicing, e‑way bills, data triangulation) already tightened leakages. A simpler structure reduces incentives for misclassification. Net effect: wider base, steadier revenues, even if headline rates fall in pockets — a point repeatedly underscored in the Council narrative and pre‑meet coverage. (Business Standard)
5) Global signal: Policy clarity is the new incentive
For multinational boardrooms considering India‑plus‑one manufacturing or services hubs, predictable indirect taxesreduce the “India risk premium.” The Council’s move — and the process discipline around it — strengthens India’s reform brand in the same way the 2017 GST launch did, but with fewer frictions this time.

6) State finances: short‑term caution, medium‑term comfort
Lower or simplified rates can pinch near‑term state GST collections. But a broader base + analytics + a preserved high demerit rate (40%) is designed to offset that over time. Watch medium‑term revenue‑sharing data, not week‑one prints.
7) Corporate planning: cleaner capex math
When indirect tax lines stabilise, capex hurdle rates fall. That helps sectors from consumer staples to logistics to light manufacturing. Expect businesses to re‑run SKU strategies, renegotiate vendor terms, and leverage the reform in go‑to‑market plans for Q3/Q4.
What businesses should do in the next 30 days
Re‑map SKUs and contracts to the two‑rate grid; lock item‑wise interpretations from day one.
Update ERPs/e‑invoicing templates, then run parallel billing for a week to catch surprises.
Reprice and communicate: if your effective incidence falls, consider visible pass‑through (even temporary festive offers).
Re‑negotiate vendor SLAs for credit terms where working‑capital improves because of rate clarity.
Disclose cleanly: Add a public note on your website/pressroom about your GST transition steps. It builds trust with customers and investors.
What consumers can expect
Clearer billing as line‑items standardise under two slabs.
Gradual price improvements where old slabs were higher or where compliance friction was embedded in MRPs.
Better grievance redressal: fewer “classification” excuses in customer care loops.
What to watch next
Official item schedules & circulars: Rate cards and clarifications tend to follow the Council’s policy signal.
Any movement on base‑widening (longer‑term questions like electricity/petroleum remain policy choices).
Collections and compliance data over two quarters — the reform’s success metric.
A note from Kushal Dev Rathi
“Policy clarity compounds. When rules get simpler, trust gets larger — and both consumers and enterprises spend with more confidence. The two‑slab GST is a ‘confidence reform’ as much as a tax reform.”
“For entrepreneurs, the message is simple: use the simplification to move faster — on pricing, on product launches, and on partnerships. Speed is a competitive advantage that simplified taxes unlock.”
