Tax Bracket History
Colonial and early U.S. taxes went through various changes until the first income tax was established by the Revenue Act of 1861. The purpose of this income tax was to help the Union raise money to fight the Civil War against the Confederacy. This income tax affected incomes of $800 and up at a rate of 3 percent.
The first tax brackets came about in 1862. The lower tax bracket was 3 percent for income up to $10,000; the higher tax bracket was 5 percent for income over $10,000. In 1872, this income tax was repealed. Since the Civil War ended, the government no longer needed the money.
The U.S. Constitution gave the federal government the power to levy taxes "in proportion to each State's population" [source: U.S. Department of the Treasury]. When the federal government established an income tax in the 1890s, the Supreme Court declared the tax unconstitutional, because it disregarded state populations.
In 1913, the 16th Amendment to the Constitution gave the government the power to levy an income tax regardless of state population. The federal income tax has been in place ever since.
Here are some important dates in the history of the federal income tax and its tax brackets.

- 1917: War Revenue Act of 1917 increases rates. Tax brackets range from 2 percent on income of $0-$2,000 to 67 percent on income of $2 million and higher.
- 1920s: Tax rates are cut because the economy is doing well. The highest marginal rate decreases to 25 percent.
- 1930s: Big increases because of the Great Depression. Lowest rate is 4 percent. Highest rate is 79 percent. Income of $90,000-$100,000 is taxed at 59 percent. In 1933, there are 55 tax brackets, mostly in 1 percent increments.
- World War II: Great tax increases to fund the war. The lowest rate in 1944 is 23 percent, for income of $2,000 or less. The highest rate is 94 percent for income of $200,000 or more.
