Unwelcome surge: On the buoyancy in GST collections

📌 Summary:

• Context: June 2026 GST collections rose 13.9% year-on-year to ₹1.95 lakh crore, as India marks nine years of GST
• Core argument: the buoyancy is "unwelcome" — it reflects imported inflation and a weak rupee rather than genuine domestic value addition
• Breakdown: import IGST surged 34.6% (up from 17.2% in May) while domestic GST grew only 6.5%
• Causal chain: (1) May merchandise imports rose sharply on crude/petroleum (+54% YoY) and gold (+34%); (2) gold prices jumped ~60% YoY, signalling hedging rather than real activity; (3) the government hiked gold import duty from 6% to 15% on May 13, inflating import GST; (4) the rupee depreciated ~6% against the US dollar since late February; (5) higher freight and a 14.5% rise in non-oil imports at elevated global prices mechanically raised the tax base
• Corroborating weakness: the eight core industries grew only ~2.8% in Q1 FY27 (vs ~6% a year earlier); the HSBC Manufacturing PMI at 54.2 was the second-lowest in 13 months
• Structural gains acknowledged: the taxpayer base rose from ~66 lakh (2017) to over 1.65 crore, reflecting better compliance, formalisation and faster refunds
• Unresolved issues: input tax credit, litigation, and federal balance in revenue sharing
• Takeaway: headline buoyancy masks subdued domestic demand
