The correct answer is: a) Taxes.
Taxes are the main source of revenue for the Manipur budget. In 2020-21, taxes accounted for 67% of the state’s total revenue. The main types of taxes collected by the Manipur government are personal income tax, corporate tax, sales tax, and excise duty.
Central government grants are another important source of revenue for the Manipur budget. In 2020-21, central government grants accounted for 20% of the state’s total revenue. These grants are provided by the central government to help states meet their expenditure needs.
Borrowings are also a source of revenue for the Manipur government. In 2020-21, the state government borrowed Rs. 1,000 crore. This money is used to finance capital expenditure, such as infrastructure projects.
Income from state-owned enterprises is a small source of revenue for the Manipur government. In 2020-21, this income accounted for only 3% of the state’s total revenue. The main state-owned enterprises in Manipur are the Manipur State Electricity Board and the Manipur State Transport Corporation.
In conclusion, the main source of revenue for the Manipur budget is taxes. Central government grants, borrowings, and income from state-owned enterprises are also sources of revenue, but they are less important than taxes.
