Portrait of Harlan F. Stone Harlan F. Stone Helvering v. Gerhardt — Opinion of the Court

The people of all the States, and the States themselves, are represented in Congress, and, by their representatives, exercise this power. When they tax the chartered institutions of the States, they tax their constituents; and these taxes must be uniform. But, when a State taxes the operations of the government of the United States, it acts upon institutions created, not by their own constituents, but by people over whom they claim no control. It acts upon the measures of a government created by others as well as themselves, for the benefit of others in common with themselves.

But if every federal tax which is laid on some new form of state activity, or whose economic burden reaches in some measure the state or those who serve it, were to be set aside as an infringement of state sovereignty, it is evident that a restriction upon national power, devised only as a shield to protect the states from curtailment of the essential operations of government which they have exercised from the beginning, would become a ready means for striking down the taxing power of the nation.

The taxpayers enjoy the benefits and protection of the laws of the United States. They are under a duty to support its government and are not beyond the reach of its taxing power. A nondiscriminatory tax laid on their net income, in common with that of all other members of the community, could by no reasonable probability be considered to preclude the performance of the function which New York and New Jersey have undertaken, or to obstruct it more than like private enterprises are obstructed by our taxing system.
