Gregory v. Helvering, 293 U.S. 465 (1935), was a landmark decision by the United States Supreme Court concerned with U.S. income tax law. The case is cited as part of the basis for two legal doctrines: the business purpose doctrine and the doctrine of substance over form. The business purpose doctrine is essentially that if a transaction has no substantial business purpose other than the avoidance or reduction of Federal tax, the tax law will not regard the transaction. The doctrine of substance over form is essentially that for Federal tax purposes, a taxpayer is bound by the economic substance of a transaction if the economic substance varies from its legal form.

The 861 argument is a statutory argument used by tax protesters in the United States, which interprets a portion of the Internal Revenue Code as invalidating certain applications of income tax.

Tax protester Sixteenth Amendment arguments are assertions that the imposition of the U.S. federal income tax is illegal because the Sixteenth Amendment to the United States Constitution, which reads "The Congress shall have power to lay and collect taxes on incomes, from whatever source derived, without apportionment among the several States, and without regard to any census or enumeration", was never properly ratified, or that the amendment provides no power to tax income. Proper ratification of the Sixteenth Amendment is disputed by tax protesters who argue that the quoted text of the Amendment differed from the text proposed by Congress, or that Ohio was not a State during ratification, despite its admission to the Union on March 1, 1803, more than a century prior. Sixteenth Amendment ratification arguments have been rejected in every court case where they have been raised and have been identified as legally frivolous.
Tax protesters in the United States advance a number of constitutional arguments asserting that the imposition, assessment and collection of the federal income tax violates the United States Constitution.

Although constitutional challenges to U.S. tax laws are frequently directed towards the validity and effect of the Sixteenth Amendment, assertions that the income tax violates various other provisions of the Constitution have been made as well.
