4.Reforming India's Taxation Framework (GST Reforms)

Indian Express

What & Where

Goods & Services Tax (GST): value-added, destination-based indirect tax created via 101st Constitution Amendment, 2016.

Dual levy: Centre charges CGST, States charge SGST; inter-state supplies attract IGST.

Governing body: Article 279A GST Council, headquartered New Delhi, decides rates by ¾ majority.

Quick Facts for MCQs

Legal & Policy

  • Retrospective‐tax amendments overturned SC Vodafone ruling, triggered ₹8,000 cr international penalty.
  • GST Council’s 55th meeting sought retrospective levy, seen as regressive for investor trust.
  • Multiple rates on same item (e.g., popcorn 5-18 %) spur demand for rationalisation.

Economic Angle

  • Complex taxes raise production cost, induce import reliance; China purchases rose USD 30 bn since 2018-19.
  • Inverted duty structure discourages domestic manufacturing, drags sector’s GDP share below 15 %.
  • Currency pressure: higher trade deficit risks twin deficits and rupee depreciation.

Administrative Issues

  • Input Tax Credit denials inflate consumer prices; Supreme Court now permits ITC on commercial realty builds.
  • Low direct-tax capture pushes government toward high indirect levies, cess proliferation.
  • Arbitrary notices, ambiguous circulars benefit tax professionals, impede ease of doing business.

Judicial Precedents

  • Safari Retreats 2024: SC affirmed ITC on leased commercial complexes, curbing departmental discretion.
  • Vodafone verdict nullification exemplar of investor-unfriendly retrospective action.
