Inland revenue refers to all taxes except those on foreign commerce. Inland revenue is the main source of government funds in most countries. It includes taxes on personal and business income, real estate, manufacturing, inheritances, and sales. These taxes are sometimes called internal revenue.
In some countries, the term inland revenue appears in the name of the government department that collects some or all of the taxes. Countries with inland revenue departments include Malaysia, New Zealand, and Singapore. In Australia, the government’s chief revenue collector is the Australian Taxation Office. In the United Kingdom, HM Revenue & Customs collects taxes on personal income, corporate earnings, and inheritances.
In the United States, the Internal Revenue Service collects most inland revenue for the federal government. Inland revenue collected by the federal and state governments includes income, inheritance, and excise taxes. Excise taxes are those levied on a specific product or service, such as gasoline, tobacco, or liquor. Many states also levy sales taxes.
