THE SIXTEENTH AMENDMENT consists of a single sentence providing that “[t]he Congress shall have power to lay and collect taxes on incomes, from whatever source derived, without apportionment among the several States, and without regard to any census or enumeration.”
Read in isolation, this sentence may appear to be a standalone authorization for Congress to lay and collect taxes on “incomes, from whatever source derived.” Nevertheless, as explained in our brief amicus curiae available under available documents below, the Sixteenth Amendment achieves its goal of overturning the result of the Supreme Court’s decision in Pollock v. Farmers’ Loan & Trust Co., 158 U.S. 601 (1895) by modifying the post-Sixteenth Amendment jurisprudence to be applied for purposes of determining whether a federal tax on “incomes, from whatever source derived,” is or includes a federal “direct tax” for purposes of Article I of the Constitution.
The text of the Sixteenth Amendment also does not indicate whether the “incomes, from whatever source derived,” referred to therein were intended include one or more unrealized incomes or to be a measurement of an individual’s realized and/or unrealized net incomes (as contrasted to gross incomes) calculated net (and not gross) of one or more types or categories of state and local taxes, such as state and local “income,” “property,” “intangibles,” “employment,” “payroll,” “sales” or “use” taxes. Taxing one person on income earned by another person may also raise constitutional due process issues.
Certain of these issues are analyzed in our brief amicus curiae. Others are analyzed in the explanation of changes statement included as part of the SALT Deduction Refund Claim, and in other of the materials listed under available documents below.
