Detail

1. What fiscal federalism means

  • Fiscal federalism is the way a country divides three things between its levels of government:
  • the power to tax (who collects which tax),
  • the duty to spend (who pays for which service),
  • the transfers (money that moves from one level to another to close gaps).

  • India has three levels:

  • the Union (the Centre),
  • the states,
  • local bodies (panchayats and municipalities).

  • Constitutional anchors (Era line):

  • Art. 270 covers sharing of central taxes with states.
  • Art. 275 covers grants-in-aid to states that need help.
  • Art. 280 sets up the Finance Commission every five years.
  • Art. 293 covers borrowing by states.

  • Scope of sharing widened in 2000: before 2000, the Centre shared only income tax and Union excise duty on certain goods with states. A constitutional amendment in 2000 allowed all central taxes to be shared [2].

2. Who should do what: the assignment logic

  • Decentralisation theorem (Wallace Oates): a public service should be provided by the lowest level of government that covers its benefit area.
  • Benefit area means the area whose people actually use and gain from the service.
  • A street light helps one locality, so the municipality should run it. A national defence force helps the whole country, so the Centre should run it.
  • Local governments know local needs and tastes better, so they waste less.

  • Subsidiarity is the same idea: do not centralise what a smaller unit can do well.

What sits with the Centre

  • Stabilisation means managing booms and slumps in the economy.
  • Why a state cannot do it alone:
    • A state spends more during a slump to create demand.
    • Much of that money is spent on goods made in other states, so the demand "leaks out".
    • The state carries the debt while other states get much of the benefit.
  • So counter-cyclical policy (spending more in bad times and less in good times) belongs with the Centre.

  • Redistribution means moving income from rich to poor. Class 12 NCERT calls this the "redistribution function" of the budget.

  • Why a state cannot do it alone:

    • A state taxes the rich heavily.
    • The rich move to a state with lower taxes.
    • The tax base leaves, and the poor gain nothing.
  • Mobile and buoyant tax bases belong with the Centre.

  • Buoyant tax: tax revenue grows fast as GDP grows. Examples are income tax, corporation tax and customs.
  • Mobile tax base: the thing being taxed can shift easily across state lines, such as company profits or imports.
  • Why centralise them: if states taxed these bases, they would cut rates to attract firms. This tax competition (a "race to the bottom") would reduce revenue for everyone.

What sits with states

  • Services people use daily: health, school education, police, agriculture, water and local services.
  • Most of these fall in the State List of the Seventh Schedule. They cost a lot, and the cost grows over time.

3. India's two imbalances

(a) Vertical fiscal imbalance (VFI)

  • Definition: the gap between levels of government. The Centre has the stronger tax powers, while states carry the larger spending duties.
  • PRS describes it as states incurring expenditures that are out of proportion to their own sources of revenue [2].

  • Size: states account for about 60% of general government expenditure but raise a much smaller share of total revenue.

  • General government means the Centre and all states taken together.
  • The RBI tracks this as the expenditure decentralisation ratio: states' expenditure ÷ general government expenditure [7].

  • Worked example (illustrative numbers):

  • Say total government spending = ₹100 and total revenue = ₹80.
  • States spend 60% of all spending, which is ₹60.
  • States raise only 35% of all revenue, which is ₹28.
  • The vertical gap = ₹60 − ₹28 = ₹32. This must come from the Centre as tax devolution (the states' share of central taxes) plus grants.

  • How the gap is closed: by tax devolution and grants (§§3-6 of the parent note).

  • 13th FC: states got 32% of the divisible pool.
  • 14th FC: raised this to 42% for 2015-20 [3].
  • 15th FC: set it at 41% for 2021-26 [4]. The 1 point cut reflects the new UTs of J&K and Ladakh.
  • 16th FC (Chair: Dr Arvind Panagariya): report tabled on 1 February 2026 for 2026-27 to 2030-31. It kept the share at 41% [5].
  • The divisible pool is the part of central tax revenue that is shared with states. It is gross tax revenue minus cesses, surcharges and collection costs.

  • Pressure on state budgets:

  • In 2023-24, states spent 53% of their revenue receipts on salaries, pensions and interest.
  • They spent another 9% on subsidies [6].
  • So little money is left for building assets.

  • GST and untied transfers:

  • After GST (2017), states' GST revenue is still below the pre-2017 level of the taxes that GST replaced [6].
  • Untied transfers (money states can spend as they choose) from the Centre declined during the 15th FC period [6].
  • Both trends make the vertical gap harder for states to manage.

(b) Horizontal fiscal imbalance (HFI)

  • Definition: the gap among states. States differ in how much they can raise and how much they need to spend.
  • Fiscal capacity is a government's ability to raise revenue from its own tax base.
  • It is usually proxied by per capita GSDP (Gross State Domestic Product divided by population).
  • It differs several-fold between high-income states (Goa, Sikkim, Telangana, Karnataka, Haryana) and low-income states (Bihar, UP, Jharkhand).
  • PRS notes that states with lower per capita incomes have limited fiscal space to spend on growth-enhancing items [6]. Fiscal space means room in the budget after fixed costs are paid.

  • Cost disabilities are natural or social conditions that make the same service costlier to deliver.

  • Examples are hills, forests and a thin, spread-out population.
  • The North-East and Himalayan states are the main cases. A school or clinic there costs more per child or patient.

  • How FCs correct HFI: through the horizontal devolution formula, which divides the states' share among states.

Criterion 15th FC (2021-26) [4] 16th FC (2026-31) [5] What it corrects
Income distance 45% 42.5% Low fiscal capacity (equity)
Population (2011) 15% 17.5% Need
Area 15% 10% Cost disability
Forest & ecology / Forest 10% 10% Cost disability; reward for green cover
Demographic performance 12.5% 10% Rewards population control
Tax & fiscal efforts 2.5% — (dropped) Efficiency
Contribution to GDP — 10% (new) Efficiency (rewards the states that produce more)
  • Income distance is the gap between a state's per capita GSDP and the highest per capita GSDP. The larger the gap, the larger the share.
  • The 16th FC says the purpose is to "maintain equity among states" [5].

  • Contribution to GDP formula (16th FC) [5]:

  • State share = √(GSDP of state) ÷ Σ √(GSDP of all states).
  • It uses average nominal GSDP for 2018-19 to 2023-24, leaving out 2020-21 (the COVID year).
  • Worked example: State A has GSDP ₹400, State B ₹100 and State C ₹25.
    • The square roots are 20, 10 and 5, which add up to 35.
    • The shares are A = 20/35 ≈ 57%, B ≈ 29% and C ≈ 14%.
    • By plain GSDP, A would have got 400/525 ≈ 76%. Taking the square root dampens the advantage of large states, so equity is not lost entirely.

4. Fiscal equalisation and its limits

  • Fiscal equalisation means designing transfers so that every state can provide comparable services at comparable tax rates, even though fiscal capacity is unequal.
  • Classic models are Canada (equalisation payments) and Australia (the Commonwealth Grants Commission).
  • In India, the heavy weight on income distance is the main equalising tool [4][5].

  • Gap-filling grants:

  • The 15th FC gave ₹2.9 lakh crore in revenue deficit grants to 17 states for 2021-26 [4]. A revenue deficit is revenue spending minus revenue receipts.
  • The 16th FC discontinued revenue deficit grants [5]. This is a clear move away from gap-filling.

Incentive problems

  • Penalising efficiency:
  • A state grows faster, so its per capita GSDP rises.
  • Its income distance shrinks, so its share of devolution falls.
  • Result: good performance is "taxed" by the formula.

  • Moral hazard of gap-filling: moral hazard means taking more risk because someone else will pay.

  • The Centre covers every deficit.
  • States then have little reason to control spending or raise their own taxes.
  • This is why deficit grants are now being withdrawn [5].

  • Southern states' grievance:

  • Karnataka, Kerala, Tamil Nadu and others contribute more to central taxes than they get back.
  • They are also penalised on the population criterion because they controlled population growth early.
  • FCs responded with demographic performance (12.5% → 10%) and the new contribution to GDP (10%) criteria [4][5].

Accounting link (Class 12, Government Budget and the Economy)

  • Grants to state governments count as Union revenue expenditure, "even though some of the grants may be meant for creation of assets".
  • Loans to states count as Union capital expenditure, because they create a financial claim.
  • Worked example: the Centre gives a state a ₹1,000 crore grant to build a hospital.
  • In the Union accounts, this is recorded as revenue expenditure.
  • So it raises the Union's revenue deficit, even though an asset is created. (The effective revenue deficit concept removes such grants.)
  • If the same ₹1,000 crore is given as a loan, it is capital expenditure.

The core trade-off

  • Equity (equalisation) and efficiency (rewarding performance) pull in opposite directions throughout §§3-6.
  • Trend:
  • 15th FC: efficiency (tax effort) got 2.5%.
  • 16th FC: efficiency (contribution to GDP) gets 10%, and deficit grants have ended [4][5].
  • So the balance is shifting towards efficiency, but equity (income distance at 42.5%) is still the largest weight.

Prelims Hooks

  • Decentralisation theorem: Wallace Oates. A service goes to the lowest level of government covering its benefit area. Subsidiarity is the same principle.
  • Vertical imbalance = Centre vs states (revenue powers vs spending duties). Horizontal imbalance = state vs state (fiscal capacity and cost disabilities). Exam trap: do not swap the two.
  • States account for about 60% of general government expenditure. RBI's expenditure decentralisation ratio = states' expenditure ÷ general government expenditure [7].
  • States' share of the divisible pool: 13th FC 32% → 14th FC 42% [3] → 15th FC 41% [4] → 16th FC 41% (2026-31) [5].
  • 16th FC: Chair Arvind Panagariya. Report tabled 1 Feb 2026. New criterion "Contribution to GDP" (10%) uses the square root of GSDP. It replaced tax & fiscal effort [5].
  • Income distance weight: 45% (15th FC) → 42.5% (16th FC). It is the largest criterion in both [4][5].
  • The 16th FC discontinued revenue deficit grants. The 15th FC gave ₹2.9 lakh crore to 17 states [4][5].
  • Since the 2000 amendment, all central taxes are shareable. Earlier, only income tax and some Union excise duties were [2].
  • Grants to states = Union revenue expenditure. Loans to states = Union capital expenditure (NCERT Class 12).
  • Stabilisation and redistribution are central functions. Stabilisation is central because of spending leakage across states. Redistribution is central because the rich can move.

Mains Points

  • VFI is built into India's design, not an accident. Buoyant, mobile taxes sit with the Centre to prevent tax competition. Daily services sit with states for better local knowledge (Oates/subsidiarity).
  • The 41% devolution share closes only part of the gap [5].
  • A falling share of untied transfers weakens states' autonomy [6].
  • Cesses and surcharges sit outside the divisible pool, which widens the gap further.

  • Equity vs efficiency:

  • Income distance (42.5%) transfers money to Bihar, UP and Jharkhand. But it penalises fast-growing states, which feeds the southern states' grievance.
  • The 16th FC's square-root contribution to GDP criterion (10%) and the end of revenue deficit grants reduce moral hazard while keeping equalisation dominant [5].

  • Shrinking fiscal space limits equalisation:

  • States spend 53% of revenue receipts on salaries, pensions and interest (2023-24) [6].
  • GST collections are below pre-2017 levels [6].
  • So transfers alone cannot ensure "comparable services at comparable tax rates". States also need own-revenue reform and better GST buoyancy (GS-III: fiscal policy; GS-II: federalism).

  • International lesson: Canada and Australia's CGC equalise both fiscal capacity and cost disabilities using explicit formulas. India's area and forest criteria are partial proxies for cost disability. This supports a case for a more explicit needs-based measure.
