In several Indian households, there is one person who quietly tracks all the expenses. Right from utility bills to school fees to online orders, there is someone who takes down the notes, often without saying anything.
Then, at the end of the month or after a few months, this person sits down with everyone and presents a complete picture of all the monetary transactions. They may even ask questions about expenditures that could have been handled better.
When it comes to auditing the receipts of the Government of India, state governments, autonomous bodies and corporations, the Comptroller and Auditor General of India (CAG) does the same.
What Is CAG?
A constitutional authority in India, the CAG was established under Article 148 of the Indian Constitution. It is empowered to audit the financial statements of the central and state governments. It also audits books of the central and state government undertakings, including those of defence services.
The President of India appoints the CAG. The appointment is based on the advice of the Prime Minister of India. CAG's tenure is 6 years or until further orders. CAG can be removed from the office only through a presidential order after an address in both houses of Parliament. It must be supported by at least two-thirds of the majority of members who are present and voting.
Roles And Functions Of CAG
- Audit Of Government Funds
CAG audits how money is spent from the Consolidated Fund of India. It is the primary account of the Union government that holds all revenues received, loans raised and loan repayments. CAG also audits the consolidated fund of each state and union territory. It verifies if the money was used for approved purposes following proper rules.
- Audit Of Contingency And Public Accounts
CAG also audits the Contingency Fund of India. This fund acts as a reserve for unforeseen government expenses. It also checks similar funds at the state level. Additionally, it reviews the Public Account of India and the public accounts of states. These accounts hold other public money, including small savings, provident funds, etc.
- Audit Of Government Bodies And Companies
CAG also audits receipts and expenditures of bodies that receive large financial support from the government. These include:
-
Government companies

Corporations

Bodies funded by the central and state governments
Along with these, CAG also audits the trading, manufacturing, balance sheet and profit and loss accounts by any department of the central and state governments.
What Is CAG Audit?
A CAG audit refers to the comprehensive and independent examination of the central or state government's transactions by CAG. Through its audit, CAG establishes accountability and transparency in spending. CAG audit is of various types, including:
-
Financial audits that check the accuracy of the accounts
-
Compliance audits that ensure adherence to rules
-
Performance audits that ensure the efficiency of government programmes
CAG presents its audit report to the Indian President or the governor, who then tables it before the Parliament or state legislature.
What Is A CAG Report?
The CAG report is the official and independent audit report submitted to the Indian Parliament or the respective state legislature. This report highlights any irregularities or inefficient project management, if any.
Through its audit report, CAG:
-
Establishes if the taxpayer's money has been used efficiently and lawfully
-
Highlights areas such as revenue leakage, excessive expenses, increasing liabilities, etc
Importance Of CAG In India
In a democratic country like India, the CAG plays a vital role. Here is how it is important to India’s federal structure:
- Keeps A Check On Government Spending
The government collects money through taxes, and CAG checks if the money is being spent in the right way. It finds out if the spending follows the rules and whether the money is being used for the purpose it is meant for. This prevents careless spending.
- Protects Public Money
The money that the government uses comes from the public in some way or other. CAG ensures this money is not wasted or misused. CAG flags if something is wrong, and it helps in fixing problems and avoiding losses.
- Helps Build Trust
CAG helps build trust among citizens as its report tells people how their money is being used. Through CAG's report, citizens get a clear picture of the government's spending patterns. It brings transparency to the process.
Example Of CAG Functioning
Suppose the government announces a highway project worth ₹1,000 crore. Once the work starts, different departments and contractors get the money. After some time, CAG checks the records and looks at:
-
The money actually spent
-
If the highway is being built as per the plan
-
If the cost is reasonable
It also checks if:
-
Full payment is being made despite the work not being completed
-
The cost of materials is shown as higher than the actual
-
Contracts are awarded without proper process
CAG writes them all in its report.
Conclusion
As the supreme audit authority, CAG's meaningful reports go a long way in ensuring the government's financial integrity. Its impactful reports make it one of the most vital institutions of a transparent and ethical government framework.
