Title: Federal budget (economics)
Content:  The revenue for the federal budget each fiscal year is arranged and administered by the government and is then supplied in the form of taxation. These taxes can come in a wide variety of sources such as a tax on one's income, profits from a business and the country's imports (duties and tariffs). Revenue can also be streamed from activities that the government strongly discourages often called a Sin tax and the government can then tax on commodities such as smoking and alcohol consumption. Federal governments don't necessarily exist in every country due to it largely depending on the size and population of the country. The United Kingdom currently doesn't require federal governments but in the United States for example this model is needed as there exists mass population throughout the country in addition to the diverse group of people with diverse needs but federal government suits due to the common culture and values set in place.

Title: Tariff in United States history
Content:  Tariffs were the greatest (approaching 95% at times) source of federal revenue until the federal income tax began after 1913. For well over a century the federal government was largely financed by tariffs averaging about 20% on foreign imports. At the end of the American Civil War in 1865 about 63% of Federal income was generated by the excise taxes, which exceeded the 25.4% generated by tariffs. In 1915 during World War I tariffs generated only 30.1% of revenues. Since 1935 tariff income has continued to be a declining percentage of Federal tax income.

Title: Excise tax in the United States
Content:  federal government out on a sound financial basis with good credit and a regular, easily collected source of revenue. Customs duties (tariffs) on imported goods, as set by tariff rates, were the source of about 80–95% of all federal revenue up to 1860. Having just fought a war over taxation (among other things) the U.S. Congress wanted a reliable source of income that was relatively unobtrusive, brought in enough money to pay off the debt and pay for the relatively low cost federal government (at the time) and be relatively easy to collect. Tariffs met all these criteria. In addition to tariffs, low 
Title: History of taxation in the United States
Content:  Tariffs have played different parts in trade policy and the economic history of the United States. Tariffs were the largest source of federal revenue from the 1790s to the eve of World War I until it was surpassed by income taxes. Since the revenue from the tariff was considered essential and easy to collect at the major ports, it was agreed the nation should have a tariff for revenue purposes.

Title: Tax expenditure
Content:  to nearly half of all federal revenue ($3.5 trillion). The CBO has also estimated the size of major tax expenditures on federal receipts as an annual average percent of GDP, for the period of 2016 to 2026. These included, among others: The CBO projected that the top 10 largest tax expenditures would average 6.2% GDP each year on average over the 2016-2026 period. For scale, federal tax receipts averaged around 18% GDP from 1970 to 2016. The CBO analysis does not account for behavioral changes that might occur if the tax policies were changed, so the actual revenue impact would differ from the amounts indicated.
