What Happened

Tamil Nadu faces a structural fiscal squeeze: the state's inclusive growth model — which involves heavy investment in welfare schemes, public health, education, and infrastructure — is increasingly constrained by limited fiscal space relative to its development ambitions.
The state argues that its fiscal challenge is not about profligacy or misgovernance, but about the design of Centre-State fiscal relations — specifically, the shrinking share of central taxes that reach states and the growing burden of Centrally Sponsored Schemes (CSS) that tie state spending to central priorities.
Tamil Nadu's fiscal deficit has hovered near the FRBM-mandated ceiling of 3% of GSDP, leaving little room to expand spending without breaching limits.
The state is demanding greater fiscal autonomy — including a higher share of central taxes (states demand 50% of the divisible pool, up from the current 41%), and reforms to how GST revenues are distributed.
The core challenge identified: generating enough investment, decent employment, and wage growth while renegotiating fiscal space with the Union government — a structural tension between an industrialised, high-compliance state and a federal fiscal architecture that tends to favour equalisation over growth.

Finance Commission — Constitutional Basis and Role

The Finance Commission is a constitutional body established under Article 280 of the Constitution of India. It is constituted by the President every five years (or earlier if needed) to recommend the principles governing the distribution of tax revenues between the Centre and States, and among states.

Article 280: Mandates constitution of the Finance Commission and specifies its terms of reference
Vertical devolution: Determines what share of the divisible pool of central taxes goes to states; the 15th Finance Commission (2021–26) set this at 41% (reduced from 42% by the 14th FC to account for J&K's bifurcation into Union Territories)
Horizontal devolution: How that 41% is distributed among states; criteria include income distance (poorer states get more), demographic performance (states that controlled population growth are rewarded), area, forest cover, and tax effort
The 16th Finance Commission (2026–31) introduced "Contribution to GDP" with a 10% weight, which marginally benefits industrialised states like Tamil Nadu and Karnataka
Tamil Nadu demands: 50% devolution (up from 41%), and inclusion of states' GDP contribution as a key criterion

Connection to this news: Tamil Nadu's fiscal squeeze is partly structural — as a richer state with strong tax compliance and controlled population growth, it contributes more to the national pool than it receives back under the current equalisation-focused horizontal devolution formula.

Divisible Pool — What States Actually Receive

The "divisible pool" is the aggregate of central tax revenues — income tax, corporate tax, customs, and central GST — that are constitutionally mandated to be shared with states. Critically, not all central revenue enters this pool.

Cesses and surcharges collected by the Centre do not form part of the divisible pool and are not shared with states; this has been a growing source of Centre-State friction
As cesses (e.g., health and education cess, Swachh Bharat cess, GST compensation cess) have grown as a share of central revenues, states' effective share of total central revenues has declined below the notional 41%
States like Tamil Nadu, Karnataka, Kerala, Maharashtra, and Gujarat — which generate the bulk of central tax revenues — receive relatively less back per rupee contributed
Article 269A: Governs the apportionment of IGST (integrated GST on inter-state trade) between Centre and States

Connection to this news: Tamil Nadu's demand to renegotiate fiscal space is rooted in the reality that cesses and surcharges have eroded the effective divisible pool, leaving states with less than the headline 41% figure suggests.

FRBM Act, 2003 — Fiscal Rules and State Borrowing

The Fiscal Responsibility and Budget Management (FRBM) Act, 2003 was enacted by the Central Government to impose rules-based fiscal discipline. States also have their own FRBM Acts, which cap borrowing and deficit levels.

Central Government target under FRBM: Fiscal deficit of 3% of GDP (the glide path has been revised several times post-COVID)
State FRBM limits: States are generally restricted to a fiscal deficit of 3% of GSDP; additional 0.5% borrowing permitted if power sector reforms are completed (Article 293 governs state borrowing)
Article 293 of the Constitution: States must obtain Centre's consent to borrow if they are indebted to the Centre; this gives the Centre leverage over state borrowing
Tamil Nadu's fiscal deficit: Has remained near the 3% GSDP ceiling; its debt-to-GSDP ratio has exceeded 25%, limiting additional borrowing capacity
Net Borrowing Ceiling: The Centre sets annual net borrowing ceilings for each state under its Article 293 powers; states have alleged that the Centre uses this tool to tighten their fiscal space beyond FRBM norms

Connection to this news: Tamil Nadu's argument is that while it adheres to FRBM rules, the combination of FRBM ceilings, Centre-set borrowing limits, and shrinking tax devolution together constrain its ability to sustain public investment in inclusive growth.

Centrally Sponsored Schemes (CSS) — Fiscal Implications for States

Centrally Sponsored Schemes are central government programmes where the Centre sets the design, objectives, and funding norms, and states contribute a matching share. While CSS bring resources to states, they also lock state budgets into centrally determined priorities and tie up state counterpart funds.

CSS funding pattern (typical): 60:40 Centre:State for general category states; 90:10 for special category (NE and hill states)
Number of CSS: Rationalised from over 70 to around 28 core CSS (post-2014 Shivraj Singh Chouhan Committee recommendation); the number has since grown again
Problem for Tamil Nadu: As a general category state, it contributes 40% counterpart funds for CSS; this crowds out state-priority spending
Article 282: Allows the Centre to make grants for any public purpose, even outside the Concurrent or Union List — the basis on which many CSS operate; critics argue this bypasses the Finance Commission and distorts state fiscal priorities

Connection to this news: Tamil Nadu's "growth model" depends on state-priority investments in health, education, and infrastructure, but CSS obligations and FRBM limits leave less room for discretionary state capital expenditure.
