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.
