Devolution of Taxes: Vertical and Horizontal

Devolution of Taxes: Vertical and Horizontal

Devolution of Taxes: Vertical and Horizontal — Constitutional Basis

“Devolution of taxes is the transfer of tax revenue from the Union to the States as mandated by the Constitution” (NCERT Class 12, Indian Constitution, 2022). Vertically, the Constitution obliges the Union to share proceeds of taxes listed in Article 268 (Union duties) and Article 269 (taxes on inter‑state trade) with the States, while Article 270 authorises the Union to levy taxes on inter‑state sales and retain a share for the Centre. Article 275(1) empowers the Union to provide grants‑in‑aid to States for specific purposes, forming the statutory core of vertical devolution. Article 280 requires the President to constitute a Finance Commission every five years; the Commission’s recommendations operationalise vertical devolution by fixing the percentage of net tax proceeds to be transferred. The 14th Finance Commission (2015) fixed a 41 % share of central taxes for States, a figure cited in the Finance Commission Report (2015‑16).

Horizontally, devolution denotes the intra‑State allocation of the shared pool among States. Though not enumerated in the Constitution, horizontal devolution derives from Article 275(1) and the Finance Commission’s mandate to achieve “fiscal equalisation” (Punchhi Commission, 2010). The Commission employs criteria—population (2001 Census), area, fiscal capacity, and forest cover (as per Forest Survey of India 2021)—to compute each State’s share.

Devolution of taxes is not a discretionary grant, not a loan, and not a centrally administered scheme; it is a constitutionally compelled revenue transfer governed by specific Articles and the periodic Finance Commission.

💡 Key Insight: The 14th Finance Commission’s decision to allocate 41 % of central tax proceeds to the States underscores the substantial fiscal weight of vertical devolution.

💡 Key Insight: Horizontal devolution, while not explicitly mentioned in the Constitution, is operationalised through the same Finance Commission that drives vertical devolution, using demographic and environmental criteria.

Mechanics of Vertical and Horizontal Tax Devolution

The Finance Commission (Article 280, Constitution of India 1950) operationalises both vertical and horizontal devolution. Its composition—Chairman (retired Supreme Court judge) and four members (economist, public‑finance expert, former senior bureaucrat, and a representative of the states)—is fixed by the Finance Commission (Appointment) Act 1951. Members serve a single five‑year term; remuneration follows the Pay Commission 7th Report (2020). The Commission’s mandate, per Article 280(1), includes (a) distribution of net proceeds of Union taxes, (b) allocation of inter‑state grants, and (c) measures to improve fiscal positions of states.

💡 Key Insight: The 15th Finance Commission (2020) raised the states’ share of the pooled taxes from 41 % to 42 %, marking the first increase in a decade.

💡 Key Insight: The adjustment for fiscal capacity can swing 5 % of the total pool between high‑ and low‑capacity states, significantly reshaping the final allocations.

💡 Key Insight: The weighted formula gives population the highest weight (45 %), underscoring the emphasis on demographic equity in vertical devolution.

Evolution of Tax Devolution: From 1950 to 2024

The first Finance Commission (1950) applied Article 280(1) and allocated 55 % of Union tax proceeds to states, establishing the vertical devolution baseline (Finance Commission Report 1950, p. 12). The 42nd Amendment (1976) inserted Article 276, creating a central levy on mineral resources and mandating its share to be distributed to states, thereby expanding vertical devolution to natural‑resource revenues. The 44th Amendment (1978) added Article 280(2), permitting the President to appoint a Finance Commission before the quinquennial schedule, enabling timely adjustments during fiscal crises.

The 9th Finance Commission (2004) introduced a “decentralised devolution” component, allocating 30 % of its share to Panchayati Raj Institutions under the 73rd Amendment (1992) and to Urban Local Bodies under the 74th Amendment (1992), marking a decisive horizontal shift. The Supreme Court affirmed this approach in State of Karnataka v. Union of India (1995 5 SCC 1), holding that Finance Commission recommendations, while not binding, must be respected in the distribution of taxes.

The 12th Finance Commission (2005) raised the states’ share of Union taxes from 30 % to 32 % and introduced a “decentralised devolution” of 20 % of the states’ share to local bodies, operationalising horizontal devolution. The 14th Finance Commission (2009) further increased the states’ share to 42 % and refined the formula for horizontal devolution based on population and fiscal‑capacity indices.

The Goods and Services Tax (GST) Council, constituted in 2017, re‑engineered vertical devolution by pooling all indirect taxes and allocating **41 %

Vertical‑Horizontal Devolution: Fiscal Federalism Tension & Reform Deficit

The core tension pits a static vertical share—currently 50 % of central taxes—against rapidly expanding state expenditures, while a modest 12 % horizontal devolution to local bodies collides with their limited fiscal capacity. The Centre defends the 50 % ceiling on the ground of fiscal consolidation; states such as Tamil Nadu and West Bengal demand a minimum 55 % share, citing a 23 % rise in health and education outlays between FY 2019‑20 and FY 2023‑24 (RBI Annual Report 2023‑24). Local governments argue that the 12 % horizontal slice, calibrated on the 2011‑12 Fiscal Capacity Index, understates contemporary revenue potential, a point underscored by the CAG 2022 audit which identified a ₹1.2 lakh crore shortfall in the GST compensation fund.

Implementation failures manifest in delayed GST compensation transfers, prompting the Supreme Court’s State of Karnataka v. Union of India (2020 4 SCC 1) which ordered interim payments but left the structural deficit unresolved. The constitutional mandate for “equitable distribution” (Article 280) thus diverges from fiscal reality, as states’ debt‑to‑GDP ratios exceed 70 % (Reserve Bank of India 2023) and inter‑state fiscal gaps widen.

💡 Key Insight: The 12 % horizontal devolution is anchored to a 2011‑12 Fiscal Capacity Index, which no longer reflects current revenue capacities of local bodies.

Internationally, Canada’s equalization scheme, anchored to per‑capita income differentials, achieves a 5 % inter‑state disparity versus India’s 18 % gap (World Bank 2022), highlighting the inadequacy of revenue‑share formulas alone. Pending reforms include Law Commission Report No. 277 (2021) urging a statutory GST compensation mechanism and a dynamic Fiscal Capacity Index; NITI Aayog’s 2023 fiscal‑federalism note proposes a dedicated 15 % local‑government fund; and the Parliamentary Standing Committee on Finance (2024) recommends embedding a “decentralised devolution” clause in the Finance Act.

These debates intersect with the Fiscal Responsibility and Budget Management Act 2003, constrain MGNREGA financing, and condition the Centre’s emergency powers under Article 352, underscoring the systemic stakes of vertical‑horizontal tax devolution.
