Finance, Property, Contracts
(1) All Union government revenues, borrowed money, and loan repayments form the Consolidated Fund of India; similarly for each State's Consolidated Fund. (2) All other public money received forms the public account of India / of the State. (3) No money can be withdrawn from a Consolidated Fund except in accordance with law and as this Constitution provides.
This creates the two core government bank accounts every citizen's tax payments and government finances flow through: the Consolidated Fund (holding tax revenue and borrowed money, which needs specific legal authorisation to spend from) and the Public Account (holding other public money, like provident fund deposits, that the government holds more like a trustee than an owner).
This is why any government spending ultimately needs to trace back to a proper legal appropriation from the Consolidated Fund - it's the constitutional foundation underlying the entire annual budget process (Articles 112-117 for the Union, 202-207 for states).
