Personal jurisdiction is a court's jurisdiction over the parties to a lawsuit, as opposed to subject-matter jurisdiction, which is jurisdiction over the law and facts involved in the suit. If a court does not have personal jurisdiction over a party, its rulings or decrees cannot be enforced upon that party, except by comity; i.e., to the extent that the sovereign which has jurisdiction over the party allows the court to enforce them upon that party. A court that has personal jurisdiction has both the authority to rule on the law and facts of a suit and the power to enforce its decision upon a party to the suit. In some cases, territorial jurisdiction may also constrain a court's reach, such as preventing hearing of a case concerning events occurring on foreign territory between two citizens of the home jurisdiction.
The Dormant Commerce Clause, or Negative Commerce Clause, in American constitutional law, is a legal doctrine that courts in the United States have inferred from the Commerce Clause in Article I of the US Constitution. The Dormant Commerce Clause is used to prohibit state legislation that discriminates against interstate or international commerce.
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 The decision was superseded in 1913 by the Sixteenth Amendment to the United States Constitution.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.
Landmark court decisions, in present-day common law legal systems, establish precedents that determine a significant new legal principle or concept, or otherwise substantially affect the interpretation of existing law. "Leading case" is commonly used in the United Kingdom and other Commonwealth jurisdictions instead of "landmark case" as used in the United States.
The doctrine of nondelegation is the theory that one branch of government must not authorize another entity to exercise the power or function which it is constitutionally authorized to exercise itself. It is explicit or implicit in all written constitutions that impose a strict structural separation of powers. It is usually applied in questions of constitutionally improper delegations of powers of any of the three branches of government to either of the other, to the administrative state, or to private entities. Although it is usually constitutional for executive officials to delegate executive powers to executive branch subordinates, there can also be improper delegations of powers within an executive branch.
Though the actual definitions vary between jurisdictions, in general, a direct tax is a tax imposed upon a person or property as distinct from a tax imposed upon a transaction, which is described as an indirect tax. The term may be used in economic and political analyses, but does not itself have any legal implications. However, in the United States, the term has special constitutional significance because of a provision in the U.S. Constitution that any direct taxes imposed by the national government be apportioned among the states on the basis of population. In the European Union direct taxation remains the sole responsibility of member states.
Gross income is all a person's receipts and gains from all sources, before any deductions. The adjective "gross", as opposed to "net", generally qualifies a word referring to an amount, value, weight, number, or the like, specifying that necessary deductions have not been taken into account.
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 Fifth Amendment to the United States Constitution addresses criminal procedure and other aspects of the Constitution. It was ratified in 1791 as part of the Bill of Rights. The Fifth Amendment applies to every level of the government, including the federal, state, and local levels, as well as any corporation, private enterprise, group, or individual, or any foreign government in regards to a US citizen or resident of the US. The Supreme Court furthered the protections of this amendment through the Due Process Clause of the Fourteenth Amendment.
Teschner v. Commissioner, 38 T.C. 1003 (1962) was a tax-law case involving the United States IRS in 1962.
Salvatore v. Commissioner is an opinion from the United States Tax Court that holds that a taxpayer cannot avoid paying taxes on the sale of property by first conveying that property to someone else. This opinion was later affirmed by the United States Court of Appeals for the Second Circuit. This case outlines some limitations on the "fruit-and-tree" metaphor established in Lucas v. Earl, 281 U.S. 111 (1930) and further developed in Helvering v. Horst, 311 U.S. 112 (1940). Decided in 1970, the case arose when a taxpayer tried to avoid paying capital gains tax from sale of property by giving a share in that property to her children. She then paid a gift tax, which is significantly less than the tax on the gain would have been if she had not given a share to her children.
Realization, for U.S. Federal income tax purposes, is a requirement in determining what must be included as income subject to taxation. It should not be confused with the separate concept of Recognition (tax).
Helvering v. Davis, 301 U.S. 619 (1937), was a decision by the United States Supreme Court, which held that Social Security was constitutionally permissible as an exercise of the federal power to spend for the general welfare, and did not contravene the 10th Amendment. The Court's 7–2 decision defended the constitutionality of the Social Security Act of 1935, requiring only that welfare spending be for the common benefit as distinguished from some mere local purpose. It affirmed a District Court decree that held that the tax upon employees was not properly at issue, and that the tax upon employers was constitutional.
Welch v. Helvering, 290 U.S. 111 (1933), was a decision by the United States Supreme Court on the difference between business and personal expenses and the difference between ordinary business deductions and capital expenses. It is one of the most important income tax law cases.
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.
The step transaction doctrine is a judicial doctrine in the United States that combines a series of formally separate steps, resulting in tax treatment as a single integrated event. The doctrine is often used in combination with other doctrines, such as substance over form. The doctrine is applied to prevent tax abuse, such as tax shelters or bailing assets out of a corporation. The step transaction doctrine originated from a common law principle in Gregory v. Helvering, 293 U.S. 465 (1935), which allowed the court to recharacterize a tax-motivated transaction.
Poe v. Seaborn, 282 U.S. 101 (1930), was a United States Supreme Court case in which the Court held that a married person's income may be divided with his spouse in a community property state because by operation of state law, the income earned by one spouse is immediately the one half the property of the other spouse. Unlike the Supreme Court's holding in Lucas v. Earl in which the opinion disallowed income splitting because it would have constituted an assignment of income over which the taxpayer had control, the one half of income earned by taxpayer was immediately income of his spouse and the taxpayer could not decide otherwise.
Davis v. Michigan, 489 U.S. 803 (1989), is a case in the Supreme Court of the United States holding that states may not tax federal pensions if they exempt their own state pensions from taxation. In the 1930s, the federal and state governments began to charge income tax on salaries paid to each other's employees. However, reciprocal treatment was required under the doctrine of intergovernmental immunity. The Court's ruling extended the reciprocity to pensions, since they are a form of deferred compensation for services previously rendered by an employee.
