The Sixteenth Amendment, ratified in 1913, expanded on Congress’s taxing power. Article I grants Congress authority to collect taxes,
1 but requires direct taxes to be imposed proportional to the population of the states.
2 The Sixteenth Amendment clarified that Congress has the power to collect an income tax without apportionment among the states, and without regard to population.
3 As discussed in the following essays, the Amendment was adopted in response to a Supreme Court decision that invalidated a federal income tax after holding it was a direct tax that was not properly apportioned.
4 Accordingly, the Sixteenth Amendment essentially creates an income tax exception to the requirement in Article I that direct taxes must be apportioned based on states’ population.
5 This has raised the question—again, discussed in the following essays—of what counts as income, and whether any given federal tax extends beyond income.
6 The Court has stated the test generally as whether the law taxes payments that qualify as profits or gains,
7 although this applies regardless of whether the particular transaction results in net profit.
8 The Sixteenth Amendment applies to income derived from whatever source, and thus can be subject to a somewhat broad interpretation.
9 Nonetheless, the apportionment exception in the Sixteenth Amendment does not extend to taxes on
property, as opposed to income derived from property.
In 1913 the US established the Federal Reserve.
