the largest part of the revenue of a country is derived from

The largest part of the revenue of a country is typically derived from indirect taxation. Indirect taxes are taxes on goods and services that are paid by consumers when they purchase them, such as value-added tax (VAT) or sales tax. These taxes are collected by the government from businesses, but are ultimately paid by the consumers as they are included in the prices of goods and services. Indirect taxation is an important source of revenue for governments because it is easy to collect and does not require a large administrative infrastructure. In contrast, direct taxation, such as income tax, requires more administrative resources and may not generate as much revenue. Other sources of revenue, such as non-tax revenue, may also contribute to a country's overall revenue, but they are typically smaller than indirect taxation. Overall, indirect taxation is an important and reliable source of revenue for governments, and is often used to fund public services and infrastructure.
