income tax law: an overview
In 1913, the Sixteenth Amendment to the U.S. Constitution was ratified. It empowered Congress to tax "incomes, from whatever source derived, without apportionment among the several States, and without regard to any census or enumeration." The Internal Revenue Code is today embodied as Title 26 of the United States Code (26 U.S.C.) and is a lineal descendant of the income tax act passed in 1913, following ratification of the Sixteenth Amendment. While some states do not have an income tax (Nevada), all residents and all citizens of the United States are subject to the federal income tax. Not everyone, however, must file a return. The requirements for filing are found in 26 U.S.C. § 6011. As the largest contributor, its purpose is to generate revenue for the federal budget. In 1985 for example, the government collected over $450 billion in income tax from a total of $742 billion in total internal revenue receipts. The funds collected are essential for the shaping and preservation of a free market economy.
