Tamil Nadu Assembly adopts unanimous resolution on fair share of Central tax devolution
The Tamil Nadu Legislative Assembly unanimously adopted a resolution urging the Union government to ensure the State receives its rightful share of tax devolution from the Centre.
Moving the resolution, the State's Finance Minister called on the Centre to adopt a transparent, objective, and equitable methodology for the devolution of Union taxes.
The resolution asks that the criteria used for tax devolution should not place any State at a comparative disadvantage on account of its achievements in population stabilisation and human development.
The resolution follows the tabling of the 16th Finance Commission's report on tax devolution for 2026-31 in Parliament earlier in 2026.
Finance Commission — Article 280 and the Devolution Mechanism
Article 280 of the Constitution mandates the President to constitute a Finance Commission every five years (or earlier if needed) to recommend the distribution of the net proceeds of Union taxes between the Centre and the States, and among the States themselves. Article 270 defines the "divisible pool" — the portion of central tax revenue shared with States — while Article 275 separately empowers Parliament to provide statutory grants-in-aid to States, distinct from the Finance Commission's tax-share recommendations.
Key Details
- Finance Commission composition: a Chairman and four members, all appointed by the President (Article 280(1)).
- Divisible pool (Article 270): covers all Union taxes and duties except those under Articles 268, 269 and 269A, and excludes cesses and surcharges, which the Centre need not share with States.
- The 16th Finance Commission (Chair: Dr. Arvind Panagariya) submitted its report, tabled in Parliament on February 1, 2026, covering the period 2026-27 to 2030-31.
- Vertical devolution recommended by the 16th FC: 41% of the divisible pool to States — unchanged from the 15th Finance Commission's recommendation.
The Assembly's resolution is a direct response to the horizontal devolution formula recommended by the 16th Finance Commission — i.e., how the 41% pool is split among individual States — which Tamil Nadu argues should not penalise it for demographic and development achievements.
Horizontal Devolution Criteria — Population, Income Distance, and Performance-Linked Weights
Horizontal devolution determines each State's share within the total pool allotted to States, using a weighted formula of multiple criteria. Historically, Southern States including Tamil Nadu have argued that a shift from the 1971 Census population base to the 2011 Census (used since the 15th Finance Commission) unfairly reduces their share, since they achieved population stabilisation earlier than many northern States.
Key Details
- 16th Finance Commission's horizontal criteria: Income Distance, Population (2011 Census), Demographic Performance, Forest Cover/Ecology, and a newly introduced Contribution to GDP (10% weight).
- The Tax and Fiscal Effort criterion used by the 15th Finance Commission was dropped by the 16th Finance Commission.
- Demographic Performance criterion was introduced by the 15th Finance Commission specifically to reward States that controlled population growth despite using the 2011 Census as the population base.
- Terms of Reference for Finance Commissions are decided by the Union government, which is itself a point of Centre-State contention when States feel their fiscal effort or federal structure concerns are inadequately reflected.
Tamil Nadu's demand for a methodology that credits "contribution, fiscal effort, governance performance and developmental needs," and does not penalise population stabilisation, tracks precisely the horizontal-devolution debate around the 2011 Census base and the Demographic Performance/Contribution to GDP criteria in the 16th Finance Commission's formula.
- 16th Finance Commission Chair: Dr. Arvind Panagariya; report tabled in Parliament: February 1, 2026.
- Award period: 2026-27 to 2030-31 (five years).
- Vertical devolution recommended: 41% of the divisible pool to States (unchanged from the 15th Finance Commission).
- New horizontal-devolution criterion introduced: Contribution to GDP, weighted at 10%.
- Criterion dropped from the 15th FC formula: Tax and Fiscal Effort.
- Finance Commission constitutional basis: Article 280; divisible pool defined under Article 270; grants-in-aid under Article 275.
- Finance Commission composition: Chairman + four members, appointed under Article 280(1).
