The first income tax suggested in the United States was during the War of 1812. The idea for the tax was based on the British Tax Act of 1798. The British tax law applied progressive rates to income. The British tax rates ranged from 0.833% on income starting at £60 to 10% on income above £200. The tax proposal was developed in 1814. Because the treaty of Ghent was signed in 1815, ending hostilities and the need for additional revenue, the tax was never imposed in the United States.
