The United States has separate federal, state, and local governments with taxes imposed at each of these levels. Taxes are levied on income, payroll, property, sales, capital gains, dividends, imports, estates and gifts, as well as various fees. In 2020, taxes collected by federal, state, and local governments amounted to 25.5% of GDP, below the OECD average of 33.5% of GDP.
The Sixteenth Amendment to the United States Constitution allows Congress to levy an income tax without apportioning it among the states on the basis of population. It was passed by Congress in 1909 in response to the 1895 Supreme Court case of Pollock v. Farmers' Loan & Trust Co. The Sixteenth Amendment was ratified by the requisite number of states on February 3, 1913, and effectively overruled the Supreme Court's ruling in Pollock.
McCulloch v. Maryland, 17 U.S. 316 (1819), was a landmark U.S. Supreme Court decision that defined the scope of the U.S. Congress's legislative power and how it relates to the powers of American state legislatures. The dispute in McCulloch involved the legality of the national bank and a tax that the state of Maryland imposed on it. In its ruling, the Supreme Court established firstly that the "Necessary and Proper" Clause of the U.S. Constitution gives the U.S. federal government certain implied powers necessary and proper for the exercise of the powers enumerated explicitly in the Constitution, and secondly that the American federal government is supreme over the states, and so states' ability to interfere with the federal government is restricted. Since the legislature has the authority to tax and spend, the court held that it therefore has authority to establish a national bank, as being "necessary and proper" to that end.
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 primary focus of the doctrine is barring state protectionism. The Dormant Commerce Clause is used to prohibit state legislation that discriminates against, or unduly burdens, interstate or international commerce. Courts first determine whether a state regulation discriminates on its face against interstate commerce or whether it has the purpose or effect of discriminating against interstate commerce. If the statute is discriminatory, the state has the burden to justify both the local benefits flowing from the statute and to show the state has no other means of advancing the legitimate local purpose.
A limited liability company (LLC) is the United States-specific form of a private limited company. It is a business structure that can combine the pass-through taxation of a partnership or sole proprietorship with the limited liability of a corporation. An LLC is not a corporation under the laws of every state; it is a legal form of a company that provides limited liability to its owners in many jurisdictions. LLCs are well known for the flexibility that they provide to business owners; depending on the situation, an LLC may elect to use corporate tax rules instead of being treated as a partnership, and, under certain circumstances, LLCs may be organized as not-for-profit. In certain U.S. states, businesses that provide professional services requiring a state professional license, such as legal or medical services, may not be allowed to form an LLC but may be required to form a similar entity called a professional limited liability company (PLLC).
A tax lien is a lien which is imposed upon a property by law in order to secure the payment of taxes. A tax lien may be imposed for the purpose of collecting delinquent taxes which are owed on real property or personal property, or it may be imposed as a result of a failure to pay income taxes or it may be imposed as a result of a failure to pay other taxes.
In addition to federal income tax collected by the United States, most individual U.S. states collect a state income tax. Some local governments also impose an income tax, often based on state income tax calculations. Forty-two states and many localities in the United States impose an income tax on individuals. Eight states impose no state income tax, and a ninth, New Hampshire, imposes an individual income tax on dividends and interest income but not other forms of income. Forty-seven states and many localities impose a tax on the income of corporations.
Sales taxes in the United States are taxes placed on the sale or lease of goods and services in the United States. Sales tax is governed at the state level and no national general sales tax exists. 45 states, the District of Columbia, the territories of Puerto Rico, and Guam impose general sales taxes that apply to the sale or lease of most goods and some services, and states also may levy selective sales taxes on the sale or lease of particular goods or services. States may grant local governments the authority to impose additional general or selective sales taxes.
Tax-free shopping (TFS) is the buying of goods in another country or state and obtaining a refund of the sales tax which has been collected by the retailer on those goods. The sales tax may be variously described as a sales tax, goods and services tax (GST), value added tax (VAT), or consumption tax.
Internet tax is a tax on Internet-based services. A number of jurisdictions have introduced an Internet tax and others are considering doing so mainly as a result of successful tax avoidance by multinational corporations that operate within the digital economy. Internet taxes prominently target companies including Facebook, Google, Amazon, Airbnb, Uber.
Quill Corp. v. North Dakota, 504 U.S. 298 (1992), was a United States Supreme Court ruling, since overturned, concerning use tax. The decision effectively prevented states from collecting any sales tax from retail purchases made over the Internet or other e-Commerce route unless the seller had a physical presence in the state. The ruling was based on the Dormant Commerce Clause, preventing states from interfering with interstate commerce unless authorized by the United States Congress. The case resulted from an attempt by North Dakota seeking to collect sales tax on licensed computer software offered by the Quill Corporation, an office supply retailer with no North Dakota presence, that allowed users to place orders directly with Quill.
In United States law, a federal enclave is a parcel of federal property within a state that is under the "Special Maritime and Territorial Jurisdiction of the United States". While these enclaves, which are used for all the many federal governmental purposes, such as post offices, arsenals, dams, road, etc., and usually are owned by the government. The United States in many cases has received similar jurisdictional authority over privately owned properties which it leases, or privately owned and occupied properties which are located within the exterior boundaries of a large area as to which a state has ceded jurisdiction to the United States.
Canton Railroad Company v. Rogan, 340 U.S. 511 (1951), is a case in which the United States Supreme Court held that a state franchise tax upon the services performed by a railroad in handling imported and exported goods did not violate the Import-Export Clause of the United States Constitution.
James v. Dravo Contracting Co., 302 U.S. 134 (1937), is a 5-to-4 ruling by the Supreme Court of the United States that a state's corporate income tax did not violate the Supremacy Clause of the United States Constitution by taxing the Federal government of the United States. It was the first time the Court had upheld a tax on the federal government. The decision is considered a landmark in the field of federal tax immunity, underpins modern legal interpretations of the Supremacy Clause in the U.S. Constitution, and established the "legal incidence test" for tax cases.
In National Bellas Hess v. Department of Revenue of Illinois, 386 U.S. 753 (1967), the Supreme Court ruled that a mail order reseller was not required to collect sales tax unless it had some physical contact with the state.
Direct Marketing Association v. Brohl, 575 U.S. 1 (2015), was a United States Supreme Court case in which the Court held that a lawsuit by the Direct Marketing Association trade group about a Colorado law regarding reporting the state's tax requirements to customers and to the Colorado Department of Revenue is not barred by the Tax Injunction Act. While the case was reheard and found in favor of Colorado, the concurrence of Justice Anthony Kennedy provided a means for states to bring a challenge the ruling of Quill Corp. v. North Dakota, which has prevented states from collecting taxes from out-of-state vendors.
Comptroller of the Treasury of Maryland v. Wynne, 575 U.S. 542 (2015), is a 2015 U.S. Supreme Court decision that 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.
Article I, § 10, clause 2 of the United States Constitution, known as the Import-Export Clause, prevents the states, without the consent of Congress, from imposing tariffs on imports and exports above what is necessary for their inspection laws and secures for the federal government the revenues from all tariffs on imports and exports. Several nineteenth century Supreme Court cases applied this clause to duties and imposts on interstate imports and exports. In 1869, the United States Supreme Court ruled that the Import-Export Clause only applied to imports and exports with foreign nations and did not apply to imports and exports with other states, although this interpretation has been questioned by modern legal scholars.
Brown v. Maryland, 25 U.S. 419 (1827), was a significant United States Supreme Court case which interpreted the Import-Export and Commerce Clauses of the U.S. Constitution to prohibit discriminatory taxation by states against imported items after importation, rather than only at the time of importation. The state of Maryland passed a law requiring importers of foreign goods to obtain a license for selling their products. Brown was charged under this law and appealed. It was the first case in which the U.S. Supreme Court construed the Import-Export Clause. Chief Justice John Marshall delivered the opinion of the court, ruling that Maryland's statute violated the Import-Export and Commerce Clauses and the federal law was supreme. He alleged that the power of a state to tax goods did not apply if they remained in their "original package". A license tax on the importer was essentially the same as a tax on an import itself. Despite arguing the case for Maryland, future chief justice Roger Taney admitted that the case was correctly decided.
South Dakota v. Wayfair, Inc., 585 U.S. ___ (2018), was a United States Supreme Court case that held by a 5–4 majority that states may charge tax on purchases made from out-of-state sellers even if the seller does not have a physical presence in the taxing state. The decision overturned Quill Corp. v. North Dakota (1992), which had held that the Dormant Commerce Clause barred states from compelling retailers to collect sales or use taxes in connection with mail order or Internet sales made to their residents unless those retailers have a physical presence in the taxing state.
