Tax Protester Constitutional Arguments

Tax protester constitutional arguments are assertions that the imposition of the federal income tax violates the United States Constitution. These kinds of tax protester arguments are distinguished from related statutory arguments and conspiracy arguments, which presuppose the constitutionality of the income tax. Although the most frequent Constitutional arguments are directed towards the validity and effect of the Sixteenth Amendment, arguments exist that the income tax violates some other provision of the Constitution; or that some other provision, that would prevent the assessment of the income tax, was ratified but wrongfully excluded from the Constitution.

Other constitutional amendment arguments have been raised by tax protesters. Some argue that imposition of the income tax violates the First Amendment freedom of speech and freedom of religion. Protesters argue that the income tax violates the Fifth Amendment right against self-incrimination, the Takings Clause, or the right that no person shall be "deprived of life, liberty, or property, without due process of law". Tax protesters have argued that income taxes impose involuntary servitude in violation of the Thirteenth Amendment. Some tax protesters argue that Americans are citizens of the individual states as opposed to citizens of the United States, as the Fourteenth Amendment was not properly ratified. Another argument is a missing amendment to the Constitution, known as the Titles of Nobility Amendment, which precedes the current Thirteenth Amendment. Another argument raised is that because the federal income tax is progressive, the discriminations and inequalities created by the tax should render the tax unconstitutional. These arguments have been rejected by the courts.

The authority of the federal government has been challenged by protesters, arguing that they should be immune from federal income taxation because they are sovereign individuals or natural individuals, have not requested a privilege or benefit from the government, or are outside the "federal zone" (D.C. and various federal enclaves such as military bases). Neither the U.S. Supreme Court nor any other federal court has ruled that an income tax imposed under the Internal Revenue Code of 1986 is unconstitutional. Under the Supreme Court ruling in Cheek v. United States, a defendant in a tax evasion prosecution who has made arguments that the federal income tax laws are unconstitutional may have the arguments turned against him (or her). Such arguments, even if based on honestly held beliefs, may constitute evidence that helps the prosecutor prove willfulness, one of the elements of tax evasion.
