GST

Story hook

On the night of 30 June 2017, the Central Hall of Parliament — the same room where Nehru gave the Tryst with Destiny speech in 1947 — hosted a midnight session for only the fourth time in independent India's history. At the stroke of midnight, then-President Pranab Mukherjee and Prime Minister Modi pressed a ceremonial button. A digital ticker on the wall flipped, and India became, in effect, one country, one tax.

It was the largest tax reform in the world since the European Union's VAT harmonisation in the 1990s. Seventeen central and state levies — excise, service tax, VAT, octroi, entertainment tax, central sales tax, the lot — collapsed into a single chain called the Goods and Services Tax. The reform had been in negotiation for seventeen years across three Prime Ministers (Vajpayee proposed it in 2000, Manmohan Singh's UPA pushed it in 2010, Modi's NDA finally landed it in 2017). It required a constitutional amendment so unusual that it created an entirely new body — the GST Council — to run a tax that neither the Centre nor the States could fully control alone.

GST is, simultaneously, the biggest fiscal-federalism experiment India has ever attempted and a continuously contested compromise between revenue-hungry states, an inflation-conscious Centre, and an RBI watching the macro effects. Understanding GST means understanding how India does federalism in practice — not the textbook version.

Why this matters for UPSC

GST is a perennial top-3 Economy question on UPSC. It's been on every Mains paper since 2018 in some form, and Prelims tests the Constitutional structure (101st Amendment, Article 279A), the rate slabs, and recent GST Council decisions. Interview boards lean hard on it for fiscal-federalism probes — "What's the biggest tension in the GST Council?" is a near-guaranteed ask in any IRS or IAS interview.
