Public Finance is an economic concept and a field of study that examines the government's role in the economy, specifically how it raises and spends money to achieve economic and social objectives. The concept's modern theory began to take shape during the Enlightenment era, with Adam Smith outlining four canons of taxation in The Wealth of Nations (1776). A significant turning point was the 1930s Great Depression, when John Maynard Keynes advocated for active government intervention through fiscal policy to stabilize the economy.
In India, Public Finance operates through a constitutional mechanism that governs the finances of the Central, State, and local governments. The Constitution of India mandates the presentation of the Annual Financial Statement (Union Budget) under Article 112 before Parliament for every financial year. All government revenues, loans, and loan recoveries are credited to the Consolidated Fund of India (Article 266), and no money can be withdrawn from it without an Appropriation made by law (Article 114(3)).
Public Finance connects directly to key institutions and concepts like the Finance Commission, which is constituted under Article 280 to recommend the distribution of taxes between the Union and the States. The Comptroller and Auditor General (CAG), established under Article 148, provides oversight by auditing the government's accounts. A major recent change was the introduction of the Goods and Services Tax (GST), which replaced a multitude of indirect taxes to streamline the tax structure and is governed by Article 269A for inter-State trade. The framework is also guided by the Fiscal Responsibility and Budget Management (FRBM) Act, 2003, which imposes limits on the central government's debt and deficits to ensure fiscal discipline. The Sixteenth Finance Commission submitted its report for the award period from 2026-27 to 2030-31 to the President on November 17, 2025, continuing the mechanism of fiscal transfers.
