A tax return is the completion of documentation that calculates an entity’s or individual's income earned and the amount of taxes to be paid to the government or government organizations or, potentially, back to the taxpayer. Taxation is one of the biggest sources of income for the government. There are two types of taxes—direct and indirect—which are both parts of the tax revenue. Tax revenue is the income gained by government from taxes that are levied on income, profit, goods and services, land revenue, ownership, and transfer of property, and other taxes.[2] Total tax revenue calculated as a percentage of GDP shows the share of the country’s output collected by the government through taxes. Tax revenue is used by governments to grant sums of money to communities, the military, education, hospitals, and infrastructure.
