Government revenue is money received by a government. It is an important tool of the fiscal policy of the government and is the opposite factor of government spending. Revenues earned by the government are received from sources such as taxes levied on the incomes and wealth accumulation of individuals and corporations and on the goods and services produced, exports and imports, non-taxable sources such as  government-owned corporations' incomes, central bank revenue and capital receipts in the form of external loans and debts from international financial institutions.
