The Sixteenth Amendment (Amendment XVI) to the United States Constitution allows the Congress to levy an income tax without apportioning it among the states or basing it on Census results.
The Sixteenth Amendment to the Constitution, ratified in 1913, was written to allow Congress to tax income without the hobbling apportionment requirement. [ . . . ]. Pollock was itself overturned by the Sixteenth Amendment as to apportionment of income....his amendment exempted income taxes from the constitutional requirements regarding direct taxes, after income taxes on rents, dividends, and interest were ruled to be direct taxes in the court case of Pollock v. Farmers' Loan & Trust Co. (1895). The amendment was adopted on February 3, 1913.
