Restoring fiscal space for the States
Why is it in the News?
The GST compensation cess has been merged with the regular GST, ending the compensation mechanism for States.
This move is expected to pass on over₹2 lakh crore in tax benefits to consumers and potentially boost local demand.
Certain States fear revenue losses and erosion of fiscal autonomy, arguing that no proper estimation of losses has been made.
The decision reignites discussions on Centre-State fiscal relations, cooperative federalism, and the sharing of tax powers.

GST and Fiscal Policy
GST Introduction:
Launched in July 2017 through the 101st Constitutional Amendment.
Replaced multiple indirect taxes with a common destination-based tax, shared between Centre and States.
Initial GST compensation mechanism ensured States were not worse off due to revenue loss.
Centre-State Fiscal Relations:
Articles 246–293 govern taxation powers and transfers.
Finance Commission (Article 280) recommends devolution of funds to States.
Central transfers still account for 44% of States’ revenue receipts, with Bihar at 72% dependence, Haryana at 20%.
Dependence on Central transfers affects liquidity, fiscal autonomy, and political leverage.
Revenue Sharing History:
Pre-GST (2012-17): Centre collected 67%, States 33%. Post-GST (2018-23): ratio remained similar.
Devolution share recommended by Finance Commissions increased from 29.5% (11th FC) → 42% (14th FC), but actual devolution fell short due to cesses and surcharges, which remain non-shareable.
Overview
Impact of GST Compensation Cess Merger
Consumers may benefit from lower prices, boosting demand.
States risk revenue loss: compensation previously guaranteed annual shortfalls.
Cess and surcharge previously gave the Centre additional leverage, now merged, reducing that buffer.
Erosion of Fiscal Autonomy
GST centralises tax power in the GST Council, dominated by the Centre.
States’ ability to independently raise revenue is limited.
Progressive States (e.g., Tamil Nadu, Maharashtra) contribute more to taxes but cannot fully retain the benefits.
Structural Issues in State Finances
Expenditure responsibilities are higher at State level: health, education, agriculture, local governance.
Central transfers and grants (CSS, CFS, Finance Commission) supplement but are performance-based or conditional.
Heavy dependence on the Centre creates fiscal vulnerability and political friction, especially in opposition-ruled States.
Proposed Solutions for Greater Fiscal Autonomy
Sharing personal income tax base with States on a 50:50 basis, similar to GST.
Allowing States to top up income tax rates without altering the current levy system.
Such reforms would:
Reduce dependency on Centre.
Improve liquidity and planning.
Reward progressive States contributing higher revenue.
Comparative Perspective
Example of Canada: Federal govt collects 46%, sub-national governments 54%; federal spends 40%, provinces spend 60%.
Suggests a model where States have more autonomy in raising resources and spending, improving accountability and service delivery.
Takeaway
GST restructuring is a double-edged sword: consumer benefit vs. potential revenue loss for States.
Centralised tax authority ensures uniformity but reduces State fiscal autonomy.
A dynamic approach to tax sharing and grants is critical to maintain cooperative federalism.
Fiscal reform may require structural redesign of transfers, tax bases, and conditionalities to empower States.

C2S-Scale 27B
A 27-billion-parameter foundation model trained to understand the language of individual cells.
Designed to simulate tumor-immune interactions and predict drug effects under specific cellular conditions.
The Problem
Detect emerging tumors before the immune system recognizes them.
Tumors often evade immune detection, requiring strategies to trigger antigen presentation and immune response.
Traditional Methods vs AI
Large Language Models or small AI tools could not capture complex tumor-immune signaling.
AI simulated 4000+ drugs in virtual environments mimicking low interferon signaling, a key immune evasion scenario.
Overview
Novel Approach
AI predicted drug candidates that boost immune signals selectively when interferon levels are low.
Out of all AI hits:
10–30% matched known literature.
Remaining were “surprising hits” with no prior known link to tumor detection, demonstrating AI’s ability to generate novel hypotheses.
Scientific Validation
AI predictions were experimentally validated in living cells, confirming:
Silmitasertib activates immune response only under tumor-like conditions.
This suggests a new pathway for early tumor detection and immunotherapy.
Technological Significance
Shows AI as a collaborator in scientific discovery, not just a data tool.
Highlights the value of foundation models trained on cell-level biological language.
Bridges computational predictions and experimental biology, accelerating drug development timelines.
Medical and Societal Implications
Potential to detect tumors earlier, improving cancer prognosis.
Reduces reliance on trial-and-error drug testing.
Can transform personalized medicine, by tailoring therapies based on cellular immune responses.
Challenges & Next Steps
Pre-clinical and clinical trials are necessary to confirm efficacy and safety in humans.
AI models must be continuously validated and refined with experimental data.
Ethical and regulatory frameworks must govern AI-guided drug discovery.
