The finance ministry on Wednesday notified September 22 as the appointed date for GST 2.0 — the two-slab structure the Council cleared in July — publishing alongside it the transition rules that will decide whether India's biggest indirect-tax reform since 2017 lands as festival-season relief or compliance friction.
The structure is as the Council approved: a merged 8 percent standard rate absorbing the old 12 percent slab, 20 percent for the former 28 percent goods with the sin-and-luxury cess rationalised into the rate, essentials staying at nil-and-5, and the 18 percent slab — the system's workhorse — untouched. The ministry's revenue-neutrality math leans on the war quarter's lesson: compliance buoyancy, which held through an oil blockade, is projected to absorb a 40-basis-point revenue dip inside four quarters.
The transition rules are the notification's real content. Input-credit balances stranded between old and new rates carry forward at face value — the 2017 rollout's costliest ambiguity, resolved this time in the taxpayer's favour. Price-display rules require dual MRP stickers only for ninety days, not the year retailers feared. The anti-profiteering mechanism gets a sunset: complaints accepted for twelve months, then the market takes over. And tobacco's cess architecture survives untouched, the one lobby the rationalisation never threatened.
Industry's arithmetic started the moment the date published. The staples basket's effective rate falls roughly 3.5 points; consumer companies guided margin pass-through 'substantially' on analyst calls within hours, with the festival quarter as the demand stage.
The reform's September timing is the political bet: relief visible in the Diwali bill, four quarters of buoyancy data before the next budget, and a delimitation winter in which the government would rather argue about anything else.
