The Sixteenth Amendment to the United States Constitution allows the Congress to "lay and collect taxes on incomes, from whatever source derived".
Far-reaching in its social as well as its economic impact, the income tax amendment became part of the Constitution by a curious series of events culminating in a bit of political maneuvering that went awry.
The financial requirements of the American Civil War prompted the first American income tax in 1861. At first, Congress placed a flat 3-percent tax on all incomes over $800 and later modified this principle to include a graduated tax. Congress repealed the income tax in 1872, but the concept did not disappear.
Post Civil War
After the Civil War, the growing industrial and financial markets of the eastern United States generally prospered. But the farmers of the south and west suffered from low prices for their farm products, while they were forced to pay high prices for manufactured goods. Throughout the 1860s, 1870s, and 1880s, farmers formed such political organizations as the Grange, the Greenback Party, the National Farmers’ Alliance, and the People’s (Populist) Party. All of these groups advocated many reforms (see the Interstate Commerce Act) considered radical for the times, including a graduated income tax.
In 1894, as part of the Wilson-Gorman tariff bill, Congress enacted a 2-percent tax on income over $4,000. The tax in 1895 was struck down by a five-to-four decision of the U.S. Supreme Court in Pollock v. Farmers' Loan & Trust Co. It held unconstitutional any direct tax by Congress on income. A tax on income derived from property was a direct tax which Congress could impose only by the rule of apportionment according to population pursuant to Article I, Secs. 2 and 9 of the Constitution. The Pollock decision was a surprise because merely 15 years earlier the Supreme Court had unanimously upheld a similar tax during the Civil War, the only other time that Congress had tried to tax income directly.
Although radicals denounced the Court’s decision as a prime example of the alliance of government and business against the farmer, a general return of prosperity around the turn of the century softened the demand for reform. Democratic Party Platforms under the leadership of three-time Presidential candidate William Jennings Bryan, however, consistently included an income tax plank, and the progressive wing of the Republican Party also espoused the concept.
After Pollock, the Court did uphold creative taxation by Congress based on a theory that they were levied on mere "incidents of ownership" and thus were constitutional excise taxes: (1) an inheritance tax, (2) a tax affixing revenue stamps to memoranda for the sale of merchandise on commodity exchanges, (3) a war revenue tax upon tobacco being resold, and (4) a corporate income tax as an excise "measured by income" justified by the privilege of doing business in corporate form.
The income tax, long a dream of progressives, was put on the back burner until a later date and more opportune time to try again. As a few years went by, the popularity of taxing income gradually increased once more, and even was included as a topic in the 1907 State of the Union address of then president Theodore Roosevelt.
In 1909 progressives in Congress, led by Republican Senator Nelson Aldrich, Republican of Rhode Island, proposed a constitutional amendment allowing an income tax. President William Howard Taft gave an important speech in support of the effort on June 16, 1909. Shortly thereafter, a resolution proposing the 16th amendment was submitted on July 12, 1909. The amendment was ratified by one state legislature after another, and on February 25, 1913, with the certification by Secretary of State Philander C. Knox, the 16th amendment took effect. The first income tax was passed in 1913 as part of the Underwood Tariff. Since the new tariff was lower, the government needed a way to replace the lost revenue. Due to generous exemptions and deductions, less than 1 percent of the population paid income taxes at the rate of only 1 percent of net income. However, during World War I the heavy cost of the war led to much higher rates; the rates were lowered in the 1920s.
The Sixteenth Amendment settled the constitutional question of permission to tax income and, by so doing, effected dramatic changes in the American way of life. The states which ratified the amendment are as follows:

Three states rejected this amendment:
On April 13, 2000, an organization called We the People Foundation for Constitutional Education, Inc. sent delegates to Washington D.C. to argue that the 16th Amendment was not properly ratified. There are a number of questionable circumstances surrounding the ratification, including evidence that states which were claimed to have ratified it actually rejected it.
