State coffers boosted by GST as tax collections outpace economic growth
What happened
State GST (SGST) collections have grown faster than nominal GDP growth, indicating strengthened revenue mobilisation under the GST regime. This buoyancy reflects improved compliance, wider tax base, and digitisation of returns. GST, introduced in July 2017, subsumed over a dozen central and state taxes. States receive SGST on intra-state supplies plus their share of IGST on inter-state transactions. Enhanced collections reduce states' dependence on central transfers and fiscal deficit financing, improving macroeconomic stability.
Why it matters
GST buoyancy — defined as the ratio of percentage change in tax revenue to percentage change in GDP — exceeding 1.0 means tax collections grow faster than the economy. When SGST buoyancy exceeds 1, states gain fiscal space without raising tax rates, a structurally positive development.
The GST architecture matters for exam purposes: CGST goes to the Centre, SGST to states on intra-state supplies, and IGST (on inter-state and imports) is split between Centre and states based on destination principle. The GST Council, a constitutional body under Article 279A, recommends rates and policy changes, with a three-fourths majority required for decisions.
For monetary policy transmission, higher state revenues reduce the need for market borrowings (SDL — State Development Loans), which can moderate long-term yields and ease credit conditions. For NABARD, stronger state finances improve viability of state-sponsored agricultural schemes and NABARD-refinanced projects.
Fiscal federalism dimensions — the 14th and 15th Finance Commission devolution ratios, compensation cess mechanism (which ended March 2026), and States' Own Tax Revenue (SOTR) — are key static anchors the examiner regularly pairs with GST revenue data. The five-year GST compensation guarantee to states ended in June 2022; states now operate without the compensation safety net, making organic buoyancy even more significant.
