Author Credentials. The analysis is authored by K.R. Shanmugam, an Economic Consultant to the Government of Tamil Nadu and former Director of the Madras School of Economics.
Transition to 16th Finance Commission. The debate comes at a critical juncture as the recommendations of the 15th Finance Commission (FC) conclude and the 16th FC’s report is awaited in Parliament.

Erosion of Autonomy. States report a loss of fiscal flexibility following the implementation of GST and frequent rate cuts that impact their internal revenue generation.
Non-Shareable Revenues. The Centre’s increasing reliance on cesses and surcharges is a major point of contention, as these funds are not part of the divisible pool shared with States.
The Efficiency vs. Equity Debate. Successive Finance Commissions have prioritized equity, using criteria like “income distance” to help poorer States, which high-performing States argue penalizes their economic efficiency.

Misleading PAN Data. Direct tax collection figures reflect registered office locations rather than where economic activity actually occurs, complicating the claims of high-contribution States.
Corporate Hub Concentration. States like Maharashtra and Karnataka show high collections partly because multi-State firms are headquartered in Mumbai or Bengaluru, even if their products are sold nationwide.
The Production-Consumption Gap. A manufacturer in Tamil Nadu may pay taxes locally, but the income that fuels that tax is generated from consumers across every other Indian State.

Underlying Tax Base. Gross State Domestic Product (GSDP) represents the actual economic value generated within a State’s borders, making it a more accurate proxy for tax contribution.
High Statistical Correlation. Data from 2023-24 shows a 0.91 correlation between GSDP and GST collections, proving that GSDP accurately tracks the modern indirect tax base.
Uniformity Advantage. Using GSDP assumes uniform tax administration efficiency, allowing the Centre to estimate a State’s contribution without the noise of corporate headquartering data.

The “41% Devolution” Reality. While the 15th FC recommended 41% tax sharing, the actual per-State distribution reveals massive gaps between contribution and receipt.
Leading Recipients. Uttar Pradesh (15.81%) and Bihar (8.65%) received the largest shares, despite contributing significantly lower percentages (4.6% and 0.67%) to the total tax pool.
High-Contributor Deficits. Maharashtra contributed 40.3% of taxes but received only 6.64% of transfers, while Karnataka and Tamil Nadu faced similar disproportionate ratios.

Contribution vs. Transfer Table. The five-year period (2020-2025) highlights the following disparities among key States:

State	Tax Collection Share (%)	Total Central Transfer Share (%)
Maharashtra	40.3%	6.64%
Karnataka	12.65%	3.9%
Tamil Nadu	7.61%	4.66%
Uttar Pradesh	4.6%	15.81%
Bihar	0.67%	8.65%

Income Distance Flaws. The “income distance” variable is often criticized as being debatable and based on changing weights that disadvantage States as they grow wealthier.
Weak Correlation with Effort. Current devolution shares have a weak correlation (0.24) with actual tax collection shares, suggesting that fiscal “effort” is not being rewarded.
Rigidity of Centrally Sponsored Schemes. The dominance of CSS restricts States from spending money on local priorities, forcing them into a “one-size-fits-all” development model.

Identified Gainers. Nine out of 20 major States would see increased funding if GSDP were the primary criterion, including Gujarat, Maharashtra, and Karnataka.
Impact on Poorer States. States like Bihar and Uttar Pradesh would see reductions, but the shift would be “moderate” compared to the current sharp imbalances.
Balancing Equity and Efficiency. GSDP provides a middle ground (0.58 correlation) that acknowledges a State’s contribution to national wealth while still allowing for redistribution.

Acknowledging National Contribution. Using GSDP acknowledges the hard work of States in growing the national economy, fostering a sense of reward for performance.
Improving Fairness Perceptions. A formula-based on GSDP is seen as more transparent and less prone to political or arbitrary adjustments by Finance Commissions.
Stabilizing State Finances. Greater predictability in transfers would allow high-growth States to plan long-term infrastructure and social projects without fearing sudden drops in devolution.

Increasing GSDP Weight. The 16th FC is urged to assign a higher weight to GSDP to better reflect the accrual of central revenues at the local level.
Addressing Regional Disparities. The new formula should balance expenditure needs with fiscal capacity, ensuring that the most productive regions aren’t drained of resources.
Averting Fiscal Conflict. Adopting more “objective” proxies like GSDP could reduce the growing friction between Southern/Western performing States and the Central government.
