Government needs large amounts of resources to perform various political, social and economic duties to maximize welfare. Public revenues, which include taxes and non-tax sources of income, are these key resources. Tax revenues come from direct taxes like income tax and corporate tax, as well as indirect taxes like VAT, GST, customs and excise duties. Non-tax revenues include fees, fines, and proceeds from public enterprises. When revenues from taxes and non-tax sources are insufficient, the government obtains capital receipts through borrowing from small savings, provident funds, and loan recoveries. Overall, a just tax system that raises adequate and stable revenues is vital for a country's development.
