The federal government of the United States (as well as some state and municipal governments) imposes an income tax on the taxable income of individuals, corporations, trusts, decedents' estates and certain bankruptcy estates. The income tax was first imposed during the Civil War, then again, after the 16th Amendment was ratified in 1913. Current income taxes are imposed under various provisions of Subtitle A of the Internal Revenue Code of 1986, as amended.
In addition, the Constitution specifically limited Congress' ability to impose direct taxes, by requiring it to distribute direct taxes in proportion to each state's census population. It was thought that head taxes and property taxes (slaves could be taxed as either or both) were likely to be abused, and that they bore no relation to the activities in which the federal government had a legitimate interest. The fourth clause of section 9 therefore specifies that, "No Capitation, or other direct, Tax shall be laid, unless in Proportion to the Census or enumeration herein before directed to be taken."
The courts have generally held that direct taxes are limited to taxes on people (variously called "capitation", "poll tax" or "head tax") and property (Penn Mutual Indemnity Co. v. C.I.R., 227 F.2d 16, 19-20 (3rd Cir. 1960)). All other taxes are commonly referred to as "indirect taxes," because they tax an event, rather than a person or property per se. (Steward Machine Co. v. Davis, , pp.581-582) What seemed to be a straightforward limitation on the power of the legislature based on the subject of the tax proved inexact and unclear when applied to an income tax, which can be arguably viewed either as a direct or an indirect tax.
The Court then enunciated what is now understood by Congress and the Courts to be the definition of taxable income, "instances of undeniable accessions to wealth, clearly realized, and over which the taxpayers have complete dominion." Id. at 431. The defendant in that case suggested that a 1954 rewording of the tax code had limited the income that could be taxed, a position which the Court resoundingly rejected, stating:
Id. at 432-33. Tax statutes passed after the ratification of the Sixteenth Amendment in 1913 are sometimes referred to as the "modern" tax statutes. Hundreds of Congressional acts have been passed since 1913, as well as several codifications (i.e., topical reorganizations) of the statutes (see Codification).
Central Illinois Public Service Co. v. United States, 435 U.S. 21 (1978), confirmed that wages and income are not identical as far as taxes on income are concerned, because income not only includes wages, but any other gains as well. The Court in that case noted that in enacting taxation legislation, Congress "chose not to return to the inclusive language of the Tariff Act of 1913, but, specifically, 'in the interest of simplicity and ease of administration,' confined the obligation to withhold taxes to 'salaries, wages, and other forms of compensation for personal services'" and that "committee reports ... stated consistently that 'wages' meant remuneration 'if paid for services performed by an employee for his employer'". Id. at 27.
Other courts have noted this distinction in upholding the taxation not only of wages, but also of personal gain derived from other sources - but there are limitations to the reach of income taxation. For example, in Conner v. United States, 303 F. Supp. 1187 (S.D. Tex. 1969), aff’d in part and rev’d in part, 439 F.2d 974 (5th Cir. 1971), a couple had lost their home to a fire, and had received compensation for their loss from the insurance company, partly in the form of hotel costs reimbursed. The court acknowledged the authority of the IRS to assess taxes on all forms of payment, but did not permit taxation on the compensation provided by the insurance company, because unlike a wage or a sale of goods at a profit, this was not a gain. As the Court noted, "Congress has taxed income, not compensation".
During World War I the top rate rose to 77 %; following the war, the top rate was scaled down (to a low of 25 %).
During the Great Depression and World War II, the top income tax rate rose again. In the Internal Revenue Code of 1939, the top rate was 75%. The top rate reached 91% during the war; this top rate remained in effect until 1964.
In 1964 the top rate was decreased to 70% (1964 Revenue Act), and then to 50% in 1981 (Economic Recovery Tax Act or ERTA).
The Tax Reform Act of 1986 reduced the top rate to 28%, at the same time raising the bottom rate from 11% to 15% (in fact 15% and 28% became the only two tax brackets).
During the 1990s the top rate rose again, standing at 39.6% by the end of the decade.
The top rate was cut to 35% and the bottom rate was cut to 10% by the Economic Growth and Tax Relief Reconciliation Act of 2001 (EGTRRA).
In 2003 the JGTRRA, or Jobs and Growth Tax Relief Reconciliation Act, was passed, expanding the 10% tax bracket and accelerating some of the changes passed in the 2001 EGTRRA.
Complexity is to some extent a separate issue from flatness of rate structures. In the United States, income tax codes are often legislatures' favored policy instrument for encouraging numerous undertakings deemed socially useful — including the buying of life insurance, the funding of employee health care and pensions, the raising of children, home ownership, development of alternative energy sources and increased investment in conventional energy. Special tax rebates granted for any purpose increase complexity, irrespective of the system's flatness or lack thereof.

| Massachusetts | Article 44 of the state constitution requires a fixed marginal tax rate within each class of income. This is not precisely a flat tax (usually defined to mean a single marginal tax rate across all classes of income) but is similar. Wages and most other income are currently taxed at 5.3%. This tax rate has moved up and down between 5% and 6% over the past few decades; in an unusual and rarely-used provision of the state tax code, taxpayers may elect to pay at the prior rate of 5.85% instead. |
