India’s Comprehensive Budgeting and Audit System: Structure and Function

Every rupee the government collects and spends passes through a tightly woven system of rules, approvals, and checks. This system, built on constitutional foundations, ensures that public money is used for public purposes – not diverted, misused, or spent without permission. The budgeting and audit framework is the backbone of this accountability, bringing together the executive, the legislature, and an independent watchdog to keep financial governance transparent.

Constitutional foundations of the budget 🔗

The entire budgetary process rests on the Constitution itself. Article 112 directs the President to lay before both Houses of Parliament a statement of estimated receipts and expenditure for every financial year. This document, known officially as the Annual Financial Statement, is what most people recognise as the Union Budget.

The fiscal year runs from 1st April to 31st March, and no part of public revenue or expenditure can remain outside parliamentary scrutiny. Other articles reinforce this framework: Article 113 governs voting on demands for grants, Article 114 deals with the Appropriation Bill, and Article 265 establishes that no tax can be levied or collected except by the authority of law. Together, these provisions make one principle non-negotiable – the executive proposes, but only the legislature authorises.

What the budget actually contains 🔗

The Annual Financial Statement separates expenditure into two broad categories. First, there are sums charged on the Consolidated Fund of India, which are not subject to a parliamentary vote. These include the salary and allowances of the President, the Chairman and Deputy Chairman of the Rajya Sabha, the Speaker and Deputy Speaker of the Lok Sabha, debt charges, the salaries and pensions of Supreme Court judges, and the salary, allowances and pension of the Comptroller and Auditor General of India. Parliament can discuss these, but cannot refuse them.

Second, there are sums required for other expenditure proposed to be made from the Consolidated Fund, which must be voted on by the Lok Sabha. The budget also distinguishes revenue expenditure (day-to-day running costs, salaries, subsidies) from capital expenditure (creation of assets like roads, buildings, and defence equipment).

Preparation of the budget 🔗

The budget is not prepared overnight. The Budget Division of the Department of Economic Affairs within the Ministry of Finance is the primary body responsible for compiling it. The process begins nearly six months before presentation, with ministries submitting their estimates of expenditure and revenue based on projected needs.

These estimates are scrutinised, negotiated, and consolidated by the Finance Ministry, which balances competing demands against available resources. The Finance Minister presents the budget on 1st February each year – a timeline introduced in 2017 so that implementation can begin before the new financial year starts. The printing of budget documents begins about a week earlier, marked by the traditional Halwa ceremony, after which officials involved are isolated in the North Block until presentation day.

Key budget documents 🔗

The budget is not a single paper but a bundle of documents. The Annual Financial Statement is the main one, accompanied by the Demands for Grants (ministry-wise estimates), the Appropriation Bill (authorising withdrawals from the Consolidated Fund), the Finance Bill (containing taxation proposals), and several statements mandated by the Fiscal Responsibility and Budget Management Act, 2003. The Finance Bill is a Money Bill as defined in Article 110, dealing with the imposition, abolition, remission, alteration or regulation of taxes.

Legislative authorisation and enactment 🔗

Once tabled, the budget undergoes a structured legislative journey. The Finance Minister’s speech is divided into Part A (general economic review) and Part B (taxation proposals). After presentation, there is a general discussion, followed by scrutiny by Departmentally Related Standing Committees, which examine the demands of various ministries.

Parliament then votes on the Demands for Grants, which are the individual ministry budgets. Only the Lok Sabha votes on these; the Rajya Sabha can only discuss them. After voting, the Appropriation Bill is introduced to authorise withdrawal from the Consolidated Fund, and the Finance Bill is passed to give legal effect to the government’s tax proposals. Without an Appropriation Act, no money can be withdrawn from the Consolidated Fund – this is the core of legislative control over public finance.

Vote on account 🔗

Since the full budgetary process usually continues until the end of April, the government needs interim authorisation to meet its expenses after 1st April. To address this, the Constitution empowers the Lok Sabha to make a grant in advance for a part of the financial year pending completion of the voting of Demands for Grants. This mechanism, known as the Vote on Account, is also used during election years when a full budget cannot be presented by the outgoing government.

Execution of the budget 🔗

Once the budget is enacted, execution begins. Ministries and departments draw funds against the amounts sanctioned to them, with the Controller General of Accounts serving as the principal accounting authority for the Government of India since accounting functions were separated from audit in 1976. Each ministry is responsible for spending within its allocation and maintaining proper records of receipts and payments.

Supplementary grants can be sought during the year if the original allocation proves insufficient, and excess grants can be regularised after the year ends – but only with parliamentary approval. This ensures that even mid-year financial adjustments remain under legislative scrutiny.

The Comptroller and Auditor General: guardian of the public purse 🔗

If the budget is the plan, the audit is the verification. The Comptroller and Auditor General of India (CAG) is the constitutional authority tasked with ensuring that money is spent lawfully and for the purpose sanctioned. The office is established under Articles 148 to 151 of the Constitution, placing it firmly outside both the executive and the legislature.

The CAG is appointed by the President and can only be removed on grounds of proved misbehaviour or incapacity, through an address by both Houses of Parliament – the same process used for removing a Supreme Court judge. Their salary is equal to that of a Supreme Court judge and cannot be varied to their disadvantage after appointment. After leaving office, the CAG cannot be appointed to any further office under the Government of India or any state government. These safeguards collectively secure the independence of the institution.

Functions and powers 🔗

The CAG’s duties are laid out in detail in the Comptroller and Auditor General’s (Duties, Powers and Conditions of Service) Act, 1971. Section 13 places a duty on the CAG to audit all expenditure from the Consolidated Fund of India, of each state, and of each Union Territory having a Legislative Assembly.

Beyond this, the CAG audits receipts paid into the Consolidated Fund, accounts of stores and stock, trading and profit-and-loss accounts of government commercial undertakings, government companies where the Union or state holds at least 51% equity, and bodies substantially financed by government grants or loans. The CAG also submits audit reports to the President (for the Union) or Governor (for states), who lay these before the respective legislatures.

An auditor, not a comptroller in practice 🔗

A curious feature of the Indian system deserves attention. Though the Constitution envisions the office as both a Comptroller and an Auditor General, in practice the incumbent fulfils only the role of Auditor General, not that of a Comptroller. This is because the office has no control over the issue of money from the Consolidated Fund – many departments are authorised to draw money by issuing cheques without specific authority from the CAG.

The CAG’s role therefore begins at the audit stage, after expenditure has already taken place. This differs from the British system, where the Comptroller and Auditor General exercises both pre-authorisation (comptroller) and post-expenditure (auditor) functions. The Indian model emphasises post-facto financial accountability rather than prior control.

Types of audit conducted 🔗

The CAG conducts several types of audits, each with a distinct focus. A regulatory or compliance audit checks whether expenditure conforms to the authority that governs it and whether rules and procedures have been followed. A propriety audit goes further to examine whether the expenditure was wise, faithful, and economical – whether, for instance, the spending was avoidable or extravagant.

A performance audit assesses economy, efficiency, and effectiveness – the “three Es” of modern public sector auditing. The Supreme Court has observed that the CAG is the principal auditor whose function is to go into the economy, effectiveness and efficiency of the use of resources by the government. Financial and commercial audits examine the accounts of government companies and commercial undertakings, while a revenue audit checks whether tax collections conform to law and rules.

The Indian Audit and Accounts Department 🔗

The CAG does not work alone. The office is supported by the Indian Audit and Accounts Department (IA&AD), staffed by officers of the Indian Audit and Accounts Service. Historically, the CAG was both the audit and accounting authority for the Centre and the States, but the accounting functions were taken away in the case of the Centre in 1976 and handed over to the Controller General of Accounts. However, the CAG continues to compile the accounts of the states.

Field offices include Accountant General (A&E) offices that compile state accounts and handle entitlement functions such as pensions and provident funds, and Accountant General (Audit) offices that audit state government activities. At the central level, Principal Directors and Directors General lead audit offices for specific functions like commercial audits, performance audits, and IT audits.

Parliamentary scrutiny through committees 🔗

Audit reports do not sit on a shelf. Once the CAG submits reports to the President, they are laid before Parliament and then examined by two key committees: the Public Accounts Committee (PAC) and the Committee on Public Undertakings (COPU). These bodies take up the findings, summon officials, and recommend corrective action. This closes the accountability loop – the executive proposes, the legislature authorises, the executive spends, the auditor examines, and the legislature reviews.

Over the decades, CAG reports have exposed significant financial irregularities – from the 2G spectrum case to coal block allocations – prompting debate, policy reform, and sometimes criminal investigations. The institution’s credibility rests on its independence and the quality of its scrutiny.

Challenges and evolving scope 🔗

The audit system is not without limitations. Secret service expenditure falls outside full CAG scrutiny, with the office having to accept a certificate from the competent administrative authority. The rise of Public-Private Partnerships has raised questions about whether such arrangements fall within the CAG’s audit purview, with critics arguing that a substantial portion of government-linked spending escapes CAG scrutiny. There are also concerns about the post-facto nature of audits, since irregularities can only be flagged after money has been spent.

In response, the institution has been evolving. In November 2025, the CAG announced the creation of two centralised specialised cadres within the IA&AD – one for audit of revenue and another for audit of expenditure – expected to deepen domain expertise in each area.

What do you think? Should the CAG’s scope be expanded to cover all Public-Private Partnerships and government-funded societies, even where government equity is minimal? And is the post-facto nature of audit sufficient in today’s fast-moving economy, or should the office reclaim a genuine “comptroller” function that approves expenditure before it occurs?
