All money the government of India receives as tax and non-tax revenue is deposited in the Consolidated Fund of India. Any payment from here, including salaries or interest on debt, has to be authorised by the Lok Sabha. This is done through the Appropriations Bill placed by the finance minister as part of the Budget papers every year. Any changes to spending also have to be cleared by Parliament. To meet delays and to provide for unexpected expenditure, the Constitution provided for setting up of the Contingency Fund as a supplement to the Consolidated Fund. The government also receives other funds, like the small savings fund, which is not its own but passes through the system and is parked in a third fund known as Public Accounts.
