The Finance Commission is a constitutional body established under Article 280 of the Constitution. It is set up by the President of India every five years (or earlier if needed). Its primary job is to recommend how the net tax proceeds collected by the Central Government should be shared with the states (vertical devolution) and how that state share should be distributed among individual states (horizontal devolution). It also recommends grants-in-aid to states under Article 275 and measures to strengthen Panchayats and Municipalities. The Finance Commission is essential for maintaining fiscal federalism in India — ensuring that both the Union and the States have adequate resources to perform their constitutional functions.

The 16th Finance Commission has recommended that states get 41% of the divisible pool of central taxes — the same as the 15th Finance Commission. The divisible pool is calculated by taking the Centre’s gross tax revenue and subtracting the cost of collection, cesses, and surcharges. Importantly, cesses and surcharges are not shared with states — this has been a persistent concern of state governments. Many states had demanded an increase to 50%, but the Commission retained 41%.

The most significant change is the introduction of “Contribution to National GDP” (10% weight) as a new parameter — replacing the “Tax and Fiscal Efforts” criterion (2.5%) used by the 15th Finance Commission. A state’s GDP contribution is calculated as the square root of its GSDP. The square root formula moderates the advantage of large economies. Other changes include: Income Distance reduced from 45% to 42.5%; Population increased from 15% to 17.5%; Area reduced from 15% to 10%; Demographic Performance redefined (from TFR-based to 1971–2011 population growth); Forest Cover expanded to include open forests.

All five southern states — Andhra Pradesh, Karnataka, Kerala, Tamil Nadu, and Telangana — gained share under the 16th FC’s revised formula. The primary reasons: (1) The new GDP Contribution parameter (10%) benefits economically productive southern states; (2) The expanded Forest Cover criterion (including open forests and 2015–2023 increase) benefits states that have actively increased forest cover; (3) Demographic Performance redefined from TFR to 1971–2011 population growth — southern states that controlled population early benefit from this. Karnataka registered the biggest gain (+0.48 percentage points). However, these states had demanded a larger increase — particularly objecting to the use of 2011 Census population data, which they argue penalises population-controlled states.

The 16th Finance Commission discontinued three types of grants provided by the 15th Finance Commission: (1) Revenue Deficit Grants — previously given to states whose expenditure exceeded their revenue; (2) Sector-Specific Grants — targeted at health, education, etc.; (3) State-Specific Grants — tailored to individual state needs. These were discontinued to encourage fiscal discipline — the Commission’s message is that states should manage their own finances better rather than relying on grants as an entitlement. Instead, the 16th FC focuses grants exclusively on local bodies and disaster management, with performance conditions attached. Critics argue this may hurt structurally revenue-deficient states.

The introduction of “Contribution to National GDP” is a landmark change for three reasons: (1) It shifts from rewarding fiscal behaviour (tax collection effort) to rewarding economic productivity (actual contribution to national GDP); (2) The square root formula moderates the advantage — if used as raw GSDP, Maharashtra and Tamil Nadu would dominate; the square root reduces this inequality; (3) It signals a broader philosophical shift — Finance Commissions increasingly want to reward states for economic performance, not just compensate them for backwardness. For UPSC, this is important because it creates a tension between equity (income distance) and efficiency (GDP contribution) in fiscal federalism — a classic Mains theme.

The 16th Finance Commission has recommended ₹4.4 lakh crore for rural local bodies and ₹3.6 lakh crore for urban local bodies — totalling ₹8 lakh crore over five years. These grants are split: 80% Basic grants (50% untied + 50% tied to sanitation/water management) and 20% Performance-based grants. Three entry-level conditions must be met before any grant is released: (1) Local bodies must be constituted as per the Constitution; (2) Provisional and audited accounts must be publicly disclosed; (3) State Finance Commissions must be timely constituted. Additionally, two new urban grants are introduced: Special Infrastructure Grants (₹56,100 crore for wastewater management in cities of 10–40 lakh population) and Urbanisation Premium Grants (₹10,000 crore for peri-urban village merger and transition policies).

The 15th Finance Commission introduced Demographic Performance (12.5% weight) to reward states for controlling population — measured using the Total Fertility Rate (TFR). States with lower TFR received higher allocation. The 16th Finance Commission has redefined this criterion — it now measures population growth between 1971 and 2011, and the weight is reduced to 10%. States that recorded lower population growth over this 40-year period receive more. The change from TFR to 1971–2011 population growth is significant: TFR measures current performance; the 1971–2011 metric rewards states that controlled population over a longer historical period. The weight reduction (12.5% → 10%) also slightly reduces the penalty on states that have higher current populations.
