The question as to the right of Congress to levy an income tax on municipal securities came up squarely in the famous Income Tax Cases[1] involving the constitutionality of the Income Tax Law of 1804. While the Supreme Court was sharply divided as to the constitutionality of other features of the law, it was unanimous as to the lack of authority in the United States to tax the interest on municipal bonds. [Footnote 1: _Pollock v. Farmers Loan & Trust Co._, 157 U.S., 429; same case on rehearing, 158 U.S., 601.] The decision in those cases is the law to-day (except in so far as it has been changed by the recent Sixteenth Amendment) with one possible limitation. It has been held that state agencies and instrumentalities, in order to be exempt from national taxation, must be of a strictly governmental character; the exemption does not extend to agencies and instrumentalities used by the state in carrying on an ordinary private business. This was decided in the South Carolina Dispensary case.[1] The State of South Carolina had taken over the business of selling liquor and the case involved a federal tax upon such business. The Court, while reaffirming the general doctrine, nevertheless upheld the tax on the ground that the business was not of a strictly governmental character. This decision suggests the possibility that if an attempt were made to tax state and municipal bonds the Court might draw a distinction based on the purpose for which the bonds were issued, and hold that only such as were issued for strictly governmental purposes were exempt. [Footnote 1: _South Carolina v. United States_, 199 U.S., 437, decided in 1905.] It remains to consider the effect of the Sixteenth Amendment. After the Supreme Court had held the Income Tax Law of 1894 unconstitutional on the ground that it was a direct tax and had not been apportioned among the states in proportion to population the Sixteenth Amendment to the Constitution was proposed and ratified. This amendment provides that the 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. When the amendment was submitted to the states for approval some lawyers apprehended that the words "incomes from whatever source derived" might open the door to the taxation by the Government of income from state and municipal bonds. Charles E. Hughes, then Governor of New York, sent a special message to the Legislature opposing ratification of the amendment on this ground.
