Income tax has not always been considered constitutional in the U.S.; while authorized in 1861 for the Civil War, it was repealed in 1872, and an 1894 attempt was ruled unconstitutional. It became permanently legal with the 16th Amendment's ratification in 1913, which permitted Congress to levy taxes on income without apportioning them among states.
On February 25, 1913, the 16th Amendment officially became part of the Constitution, granting Congress constitutional authority to levy taxes on corporate and individual income.

Under this estimate, we assume that if income taxes were eliminated for those making up to $150,000, taxes phased back in gradually up to $200,000 of income, and the rest of the tax code were to remain unchanged then revenue would fall by roughly $10 trillion – or 2.7 percent of GDP – over a decade.
