Tax Facts for Independence Day 2013

July 03, 2013

Taxpayers across the country will celebrate the 237th anniversary of American independence on July 4th this year. As students of history will remember, one of the chief complaints of the American colonists against the British government in 1776 was unfair and burdensome taxation (including 18th century tax breaks for big business). With that in mind, the Tax Foundation presents a few facts for Independence Day that highlight the changing American tax system.
