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.
Santa Clara County v. Southern Pacific Railroad Company, 118 U.S. 394 (1886), is a corporate law case of the United States Supreme Court concerning taxation of railroad properties.

Pollock v. Farmers' Loan & Trust Company, 157 U.S. 429 (1895), affirmed on rehearing, 158 U.S. 601 (1895), was a landmark case of the Supreme Court of the United States. In a 5-4 decision, the Supreme Court struck down the income tax imposed by the Wilson–Gorman Tariff Act for being an unapportioned direct tax. The decision was superseded in 1913 by the Sixteenth Amendment to the United States Constitution, which allows Congress to levy income taxes without apportioning them among the states.

Eisner v. Macomber, 252 U.S. 189 (1920), was a tax case before the United States Supreme Court that is notable for the following holdings:
A gift tax, known originally as inheritance tax, is a tax imposed on the transfer of ownership of property during the giver's life. The United States Internal Revenue Service says that a gift is "Any transfer to an individual, either directly or indirectly, where full compensation is not received in return."
For households and individuals, gross income is the sum of all wages, salaries, profits, interest payments, rents, and other forms of earnings, before any deductions or taxes. It is opposed to net income, defined as the gross income minus taxes and other deductions.
The United States federal government and most state governments impose an income tax. They are determined by applying a tax rate, which may increase as income increases, to taxable income, which is the total income less allowable deductions. Income is broadly defined. Individuals and corporations are directly taxable, and estates and trusts may be taxable on undistributed income. Partnerships are not taxed, but their partners are taxed on their shares of partnership income. Residents and citizens are taxed on worldwide income, while nonresidents are taxed only on income within the jurisdiction. Several types of credits reduce tax, and some types of credits may exceed tax before credits. Most business expenses are deductible. Individuals may deduct certain personal expenses, including home mortgage interest, state taxes, contributions to charity, and some other items. Some deductions are subject to limits, and an Alternative Minimum Tax (AMT) applies at the federal and some state levels.
United States v. Kirby Lumber Co., 284 U.S. 1 (1931), was a case in which the United States Supreme Court held that when a corporation settles its debts for less than the face amount, a taxable gain has occurred.
In economics, a gift tax is the tax on money or property that one living person or corporate entity gives to another. A gift tax is a type of transfer tax that is imposed when someone gives something of value to someone else. The transfer must be gratuitous or the receiving party must pay a lesser amount than the item's full value to be considered a gift. Items received upon the death of another are considered separately under the inheritance tax. Many gifts are not subject to taxation because of exemptions given in tax laws. The gift tax amount varies by jurisdiction, and international comparison of rates is complex and fluid.

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.
Walz v. Tax Commission of the City of New York, 397 U.S. 664 (1970), was a case before the United States Supreme Court. The Court held that grants of tax exemption to religious organizations do not violate the Establishment Clause of the First Amendment. It was the first case to articulate the "excessive entanglement doctrine" that one year later became the third prong of the Lemon test.

A., 602 U.S. ___ (2024), was a United States Supreme Court case in which the Court held that the Second Circuit Court of Appeals failed to analyze whether New York’s interest-on-escrow law was preempted as applied to national banks in a manner consistent with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and Barnett Bank of Marion Cty., N. A. v. Nelson.
Texas v. New Mexico and Colorado, 602 U.S. ___ (2024), was a United States Supreme Court case in which the Court denied the States' motion to enter the consent decree because the proposed consent decree would have disposed of the United States' Compact claims without its consent.
