Public Finance is a fundamental concept in economics that studies the income, expenditure, and debt management of the government and its impact on the economy. Its core components are public revenue (like taxes and non-tax receipts), public expenditure (developmental and non-developmental spending), and public debt (borrowing). The concept of public debt in India was first introduced by the East India Company in the 18th century to finance its military campaigns. The formal budgeting process began with the presentation of the first budget in India on April 7, 1860, by James Wilson.
The mechanism of public finance in India is rooted in the Constitution of India, 1950. The government's financial operations revolve around three funds: the Consolidated Fund of India (Article 266(1)), which holds all revenues and borrowings; the Public Account of India (Article 266(2)), which holds money held in trust like Provident Funds; and the Contingency Fund (Article 267) for emergency expenditure. The Annual Financial Statement (Union Budget) is presented under Article 112, and no money can be withdrawn from the Consolidated Fund without the authority of Parliament.
Public finance connects directly to the Finance Commission (Article 280), which recommends the distribution of tax revenues between the Union and the States. It is also governed by the Fiscal Responsibility and Budget Management (FRBM) Act, 2003, which mandates fiscal discipline by setting targets for the fiscal deficit and public debt. A recent change is the implementation of the Single Nodal Agency (SNA) system in 2021 to enhance transparency in the execution of Centrally Sponsored Schemes. Furthermore, the Income Tax Act, 1961, is being overhauled into the New Income Tax Act, 2025, which unifies the "Tax Year" to the financial year commencing on April 1.
