Pollock v. Farmers' Loan & Trust Company, 157 U.S. 429 (1895), affirmed on rehearing, 158 U.S. 601 (1895), with a ruling of 5–4, was a landmark case in which the Supreme Court of the United States ruled that the unapportioned income taxes on interest, dividends and rents imposed by the Income Tax Act of 1894 were, in effect, direct taxes, and were unconstitutional because they violated the provision that direct taxes be apportioned. The decision was superseded in 1913 by the Sixteenth Amendment to the United States Constitution. A separate holding regarding the taxation of interest income on certain bonds was overruled by the Supreme Court in 1988 in the case of South Carolina v. Baker.
Hylton v. United States, 3 U.S. 171 (1796), is an early United States Supreme Court case in which the Court held that a yearly tax on carriages did not violate the Article I, Section 2, Clause 3 and Article I, Section 9, Clause 3 requirements for the apportioning of direct taxes. The Court concluded that the carriage tax was not a direct tax, which would require apportionment among the states. The Court noted that a tax on land was an example of a direct tax that was contemplated by the Constitution.
Grosjean v. American Press Co., 297 U.S. 233 (1936), was a decision of the United States Supreme Court over a challenge to a separate sales tax on newspapers with circulation of over 20,000.
Cheek v. United States, 498 U.S. 192 (1991), was a United States Supreme Court case in which the Court reversed the conviction of John L. Cheek, a tax protester, for willful failure to file tax returns and tax evasion. The Court held that an actual good-faith belief that one is not violating the tax law, based on a misunderstanding caused by the complexity of the tax law, negates willfulness, even if that belief is irrational or unreasonable. The Court also ruled that an actual belief that the tax law is invalid or unconstitutional is not a good faith belief based on a misunderstanding caused by the complexity of the tax law, and is not a defense.
Bailey v. Drexel Furniture Co., 259 U.S. 20 (1922), was a United States Supreme Court case in which the Court ruled the 1919 Child Labor Tax Law unconstitutional as an improper attempt by Congress to penalize employers using child labor. The Court indicated that the tax imposed by the statute was actually a penalty in disguise.
Carter v. Carter Coal Company, 298 U.S. 238 (1936), is a United States Supreme Court decision interpreting the Commerce Clause of the United States Constitution, which permits the United States Congress to "regulate Commerce... among the several States." Specifically, it analyzes the extent of Congress’ power, according to the Commerce Clause, looking at whether or not they have the right to regulate manufacturing.
Commissioner v. Indianapolis Power & Light Company, 493 U.S. 203 (1990), was a United States Supreme Court case in which the Court addressed whether customer deposits constituted taxable income to a public utility company.
Department of Revenue of Kentucky v. Davis, 553 U.S. 328 (2008), is a United States Supreme Court case in which the Court upheld a Kentucky law that provides a preferential tax break to Kentucky residents who invest in bonds issued by the state and its municipalities. The Court held in a 7-2 vote that the State of Kentucky does not engage in unconstitutional discrimination against interstate commerce by exempting the interest on its bonds from residents' taxable income while taxing the interest earned on the bonds of other states. The case has national implications because thirty-six (36) states have tax schemes similar to the one at issue in Kentucky.
MeadWestvaco Corp. v. Illinois Dept. of Revenue, 553 U.S. 16 (2008), is a United States Supreme Court case concerning the extent a state may tax companies that are not based in their state.
Minneapolis Star Tribune Company v. Commissioner, 460 U.S. 575 (1983), was an opinion of the Supreme Court of the United States overturning a use tax on paper and ink in excess of $100,000 consumed in any calendar year. The Minneapolis Star Tribune initially paid the tax and sued for a refund.
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. 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. These kinds of arguments, though related to, are distinguished from statutory and administrative arguments, which presuppose the constitutionality of the income tax, as well as from general conspiracy arguments, which are based upon the proposition that the three branches of the federal government are involved together in a deliberate, on-going campaign of deception for the purpose of defrauding individuals or entities of their wealth or profits. 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.
A tax protester is someone who refuses to pay a tax claiming that the tax laws are unconstitutional or otherwise invalid. Tax protesters are different from tax resisters, who refuse to pay taxes as a protest against a government or its policies, or a moral opposition to taxation in general, not out of a belief that the tax law itself is invalid. The United States has a large and organized culture of people who espouse such theories. Tax protesters also exist in other countries.
Eastern Enterprises v. Apfel, 524 U.S. 498 (1998), is a United States Supreme Court case in which the Court held that the Coal Industry Retiree Health Benefit Act constituted an unconstitutional regulatory taking of property which required the Act to be invalidated. The import of this decision is that it was made in the context of a purely economic regulation. The plurality examines the statute and its resultant harm as an ad hoc factual inquiry based on factors delineated in Penn Central Transportation Co. v. New York City, such as the economic impact of the regulation, its interference with reasonable investment backed expectations, and the character of the governmental action. The decision thereby moved beyond the traditional notions of equal protection which had been applied to economic regulation since the time of Lochner v. New York, requiring extreme deference to Congress, and applied a regulatory takings analysis to the problem resulting in a much less deferential result. While the plurality recognizes that this is not a traditional takings case where the government appropriates private property for public use, they also state this is the type of case where the "Armstrong Principle" of preventing the government from forcing some people alone to bear public burdens which, in all fairness and justice, should be borne by the public as a whole. However, while the plurality seems to invalidate this particular law on takings grounds, the concurrences and the dissents warn of such an analysis as this should actually be examined under substantive due process or ex post facto theories.
Stanton v. Baltic Mining Co., 240 U.S. 103 (1916), is a United States Supreme Court case.
United States v. Windsor, 570 U.S. 744 (2013), is a landmark civil rights case in which the United States Supreme Court held that restricting U.S. federal interpretation of "marriage" and "spouse" to apply only to opposite-sex unions, by Section 3 of the Defense of Marriage Act (DOMA), is unconstitutional under the Due Process Clause of the Fifth Amendment. In the majority opinion, Justice Anthony Kennedy wrote: "The federal statute is invalid, for no legitimate purpose overcomes the purpose and effect to disparage and to injure those whom the State, by its marriage laws, sought to protect in personhood and dignity."
Comptroller of the Treasury of Maryland v. Wynne, 575 U.S. ___ (2015), is a 2015 U.S. Supreme Court decision which applied the dormant Commerce Clause doctrine to Maryland's personal income tax scheme and found that the failure to provide a full credit for income taxes paid to other states was unconstitutional.
Stratton's Independence, Ltd. v. Howbert, 231 U.S. 399 (1913),, was a case before the U.S. Supreme Court that addressed the question of corporate taxation.
