Principles of Fiscal Federalism: Guiding Financial Decentralization

Financial power in a federation is rarely held by a single authority. Instead, it flows across multiple tiers of government, each with its own responsibilities, resources, and constraints. This layered arrangement is what scholars call fiscal federalism, and getting its design right is essential for economic stability, equitable growth, and responsive governance. The principles that guide this system determine how revenues are raised, how expenditures are assigned, and how different levels of government cooperate without stepping on each other’s toes. Let us walk through these guiding principles and understand how they shape the financial architecture of a federal polity.

What fiscal federalism really means

The term fiscal federalism was introduced by the German-American economist Richard Musgrave in 1959, and it concerns the division of governmental functions and financial relations among different levels of government. The basic question it tries to answer is deceptively simple: which functions are best handled by the central government, and which are better left to states or local bodies? As Wallace Oates later framed it, fiscal federalism studies how competencies on the expenditure side and fiscal instruments on the revenue side should be allocated across vertical layers of administration.

In practice, this boils down to a constant balancing act. The Centre typically has stronger revenue-raising powers, while states and local governments carry the day-to-day burden of delivering public services. The distribution of power between the Centre and states as laid out by the Seventh Schedule of the Constitution creates what economists call a fiscal gap. According to the 15th Finance Commission, states control only about 37.3% of resources but shoulder 62.4% of expenditure responsibilities. The principles of fiscal federalism exist precisely to bridge such gaps fairly and efficiently.

The span of public goods

Public goods differ in the geographical area they serve. National defence, foreign policy, and currency affect every citizen, so they naturally belong to the central government. Street lighting, waste management, and primary healthcare, on the other hand, benefit specific localities, so they are best handled by municipal or panchayat bodies. The span of public goods principle argues that each service should be provided by the level of government whose jurisdiction most closely matches the geographical reach of its benefits.

This idea finds its clearest expression in Oates’ decentralisation theorem, which holds that each public service should be provided by the jurisdiction having control over the minimum geographical area that would internalise the benefits and costs of such provision. When benefits spill over into neighbouring regions, a higher tier should step in; when they are contained, the local tier is better placed.

The principle of subsidiarity

Perhaps the most widely cited principle in fiscal federalism is subsidiarity. It holds that any task that can be performed at a lower level of government should not be assigned to a higher one. As articulated in European Union doctrine and widely adopted globally, taxing, spending, and regulatory functions should be exercised by the lowest order of government unless a convincing case can be made for assigning these to higher orders.

The rationale is straightforward. Local governments understand local needs better. A gram panchayat knows which hamlet lacks safe drinking water; an urban local body knows which intersection needs a traffic signal. By pushing decisions downward, subsidiarity produces more tailored solutions and also strengthens democratic participation. The 73rd and 74th Constitutional Amendments gave this principle formal expression by creating panchayats and municipalities as the third tier of government.

Subsidiarity in practice

When the principle is genuinely applied, it matches authority with accountability. Decision-makers remain close to the people who experience the consequences of those decisions, which tends to sharpen judgement and reduce waste. A well-known formulation is that decision-making authority should sit as close as possible to where the actions that produce the outcomes will be taken.

Innovation across levels of government

A federation essentially becomes a laboratory. Different states can try different policy experiments, and successful ones can be copied by others while failures are contained. Kerala’s decentralised planning experiment, Tamil Nadu’s mid-day meal scheme that later became a national programme, and Andhra Pradesh’s e-governance initiatives are all examples of local innovation scaling up. Economists note that competition among local governments favours organisational and political innovations, and fiscal federalism creates the institutional space for this kind of experimentation to happen.

Independence and responsibility

For federalism to function, each tier must enjoy a measure of genuine autonomy. This means having its own sphere of taxation, its own areas of expenditure, and the freedom to make choices within that sphere. But autonomy without responsibility invites recklessness, which is why the principle pairs independence with responsibility. Governments that raise their own revenue tend to spend it more carefully than governments that simply receive grants. This is sometimes called the Wicksellian Connection, and it underpins the idea that there is a genuine link between revenue raising and expenditure decisions, which leads to efficiency and accountability.

Adequacy and elasticity of resources

A government that cannot fund its obligations is a government that cannot govern. The adequacy principle requires each level of government to have revenues sufficient to discharge its assigned responsibilities. The elasticity principle adds a temporal dimension: those revenues should grow in step with the economy and with rising demand for public services.

Consider primary education. As population and aspirations grow, states need increasing resources for schools, teachers, and learning materials. If a state’s tax base does not expand with the economy, the gap between needs and resources widens and service quality suffers. Elastic revenue sources such as the Goods and Services Tax are therefore crucial, as they tend to keep pace with GDP growth.

Economy and efficiency

Every rupee of tax comes at a cost to the citizen who pays it, so every rupee of expenditure must be justified. The economy and efficiency principles demand that governments minimise waste, avoid duplication, and deliver services at the lowest feasible cost. Economy focuses on the input side (how much is spent), while efficiency focuses on the output side (how much is achieved per rupee spent).

In a federal setting, efficiency also has a structural dimension. Assigning tax bases to the level of government best suited to collect them reduces administrative costs. For this reason, central governments typically assign subnational revenue bases that are relatively immobile, such as property and land, while retaining mobile bases like corporate income at the national level.

Integration and coordination

Decentralisation without coordination can produce chaos. States might engage in tax wars to attract investment, duplicate programmes, or pursue contradictory policies on shared concerns like pollution and public health. The integration and coordination principle calls for mechanisms that stitch the federation together.

Institutions such as the GST Council, the Inter-State Council, and NITI Aayog serve this integrating function by providing forums where the Centre and states can align their approaches. The constitutional provision for a Finance Commission every five years is itself an integration device, periodically recalibrating the financial balance so that fiscal arrangements remain responsive to changing economic realities.

Equity across regions and people

Not all states start from the same place. Bihar, Jharkhand, and the north-eastern states face structural disadvantages that Karnataka and Maharashtra do not. The equity principle requires fiscal federalism to actively address these disparities so that a citizen’s access to basic services does not depend solely on the accident of where she lives.

The instrument for this in India is the equalisation transfer. As Finance Commission reports have long noted, the concept of equalisation is a guiding principle for fiscal transfers because it promotes both equity and efficiency in resource use. Horizontal imbalances arise from disparities across constituent units in the federation due to different revenue-raising abilities, and devolution formulas typically give significant weight to factors like income distance, population, and area to correct for these differences.

Vertical and horizontal balance

Equity has two dimensions. The vertical dimension addresses the mismatch between the Centre’s revenue advantage and the states’ expenditure burden. The horizontal dimension addresses disparities among the states themselves. Both are central to the work of the Finance Commission, which must design transfers that correct both types of imbalance without undermining incentives for states to grow their own revenue.

Accountability to citizens

The closer the taxing authority is to the spending authority, and the closer both are to the citizen, the easier it becomes to hold governments answerable. This is the intuition behind the accountability principle. When the same tier raises the money and spends it, voters can judge its performance clearly. When money flows through opaque intergovernmental transfers, responsibility blurs and accountability weakens.

This is why excessive reliance on central grants for state spending can be problematic. A state whose budget is largely funded by the Centre has weaker incentives to improve its own tax collection, and its citizens have fewer levers to influence fiscal decisions through state-level politics.

Fiscal equilibrium

Fiscal equilibrium means keeping revenues and expenditures broadly in balance across all levels of government over the medium term. Persistent deficits at any tier create cascading problems: rising debt, crowding out of private investment, and ultimately reduced fiscal space for future generations. Equilibrium does not demand a balanced budget every year (that would be pro-cyclical and harmful during downturns), but it does require that borrowing be productive and sustainable.

Financial discipline

The final guiding principle is financial discipline. Each level of government must live within its means, honour its commitments, and avoid the temptation to push costs onto other tiers or future budgets. In India, this discipline is institutionalised through the Fiscal Responsibility and Budget Management Act at the Union level and corresponding FRBM legislation in the states. Fiscal decentralisation can contribute to a weakening of fiscal discipline if not properly managed, because the more decentralised spending decisions become, the harder it is for the central government to ensure compliance with overall fiscal targets.

Borrowing ceilings, such as the 3% of GSDP limit on state borrowing recommended by successive Finance Commissions, are one way of enforcing discipline. Transparent budgeting, independent audit institutions, and credible fiscal rules are others. Without financial discipline, even the best-designed fiscal federal architecture can collapse under the weight of accumulated deficits and debt.

Why these principles matter together

No single principle is sufficient on its own. Subsidiarity without adequacy produces local bodies that cannot deliver. Equity without accountability breeds dependence. Innovation without coordination creates fragmentation. The principles work as a system, each compensating for the weaknesses of the others. A well-functioning federation keeps all of them in dynamic balance, adjusting as the economy, technology, and social expectations evolve.

This is precisely why institutions like the Finance Commission, the GST Council, and the third tier of local government matter so much. They are the practical machinery through which abstract principles become lived realities for citizens, from a farmer in Vidarbha to a fisher in Alappuzha to a software engineer in Bengaluru.

What do you think? If you had to rank these principles in order of importance for a country at India’s stage of development, which two would you place at the top, and why? And looking at the current balance between the Centre and the states, do you think the principle of subsidiarity is being honoured in spirit, or only on paper?
