Some maintain that there is no federal statute imposing a tax on income derived from sources within the United States by citizens or residents of the United States. They argue instead that federal income taxes are excise taxes imposed only on nonresident aliens and foreign corporations for the privilege of receiving income from sources within the United States.
The premise for this argument is a misreading of sections 861, et seq., and 911, et seq., as well as the regulations under those sections.
The Law: As stated above, for federal income tax purposes, “gross income” means all income from whatever source derived and includes compensation for services. I.R.C. § 61. Further, Treasury Regulation § 1.1-1(b) provides, “[i]n general, all citizens of the United States, wherever resident, and all resident alien individuals are liable to the income taxes imposed by the Code whether the income is received from sources within or without the United States.” I.R.C. sections 861 and 911 define the sources of income (U.S. versus non-U.S. source income) for
such purposes as the prevention of double taxation of income that is subject to tax by more than one country. These sections neither specify whether income is taxable, nor do they determine or define gross income.
These frivolous assertions are clearly contrary to well-established legal precedent.
In March 2005, a federal district court in Florida barred Gregory T. Mayer from preparing false or fraudulent returns and selling fraudulent tax schemes relying upon, among other things, the frivolous section 861 argument, which falsely claims that income from sources in the United
States is not subject to federal income tax. See http://www.usdoj.gov/opa/pr/2005/March/05_tax_119.htm; see also 2005 TNT 49-63 (Mar. 14, 2005). In August 2005, a federal district court in Florida permanently barred Carel “Chad” Prater and Richard Cantwell from promoting tax-fraud scams relying on the section 861 argument.
