Overview The Finance Commission is pivotal in India’s fiscal federalism. The 16th Finance Commission (2026‑31) retains a 41% share for states in the divisible pool of central taxes, introduces a revised horizontal devolution formula, and replaces revenue‑deficit grants with performance‑linked transfers. Key Developments (2026‑31) States’ share in the divisible pool fixed at 41% , unchanged from the 15th Commission. Horizontal devolution formula now weights income distance (42.5%) , population (2011) (17.5%), demography, area, forest cover (each 10%) and adds contribution to GDP (10%) . Revenue‑deficit grants discontinued; total grants‑in‑aid reduced to ₹9.47 lakh crore over five years, with 80% basic and 20% performance‑linked. Fiscal targets: states to keep fiscal deficit ≤ 3% of GSDP ; Centre to limit deficit to 3.5% of GDP by 2030‑31. Off‑budget borrowings to be disclosed and incorporated in state budgets for greater transparency. Important Facts The vertical devolution applies only to the divisible pool, which was about 81% of the Centre’s gross tax revenue in 2025‑26 after excluding cesses and surcharges. Hence, the effective fiscal space for states hinges on the Centre’s revenue‑raising capacity. In the horizontal devolution , the new inclusion of GDP contribution aims to reward fiscally stronger states while retaining equity through the dominant income distance criterion. The shift from unconditional revenue‑deficit grants to conditional transfers signals a move towards incentivising fiscal prudence. Grants to rural and urban local bodies total ₹7.91 lakh crore , with release contingent on audited accounts and functional State Finance Commissions. UPSC Relevance Understanding the Finance Commission is essential for GS 2 (Polity) and GS 3 (Economy) as it illustrates the constitutional mechanism that balances fiscal powers, shapes inter‑governmental transfers, and enforces fiscal discipline. The evolving formulae reflect policy responses to regional inequities, debt sustainability, and the push for cooperative federalism. Way Forward While the 41% devolution provides stability, states argue for a higher share (45‑50%) and a cap on cesses to expand fiscal space. Future commissions may need to recalibrate the balance between equity (income distance) and performance (GDP contribution) and strengthen conditionality to curb off‑budget borrowing. Continuous monitoring of fiscal targets will be crucial to keep the combined Centre‑State debt within the projected 73.1% of GDP by 2030‑31.
