Charles Evans Hughes, Helvering v. Powers — Opinion of the Court
“ If the business itself, by reason of its character, is not immune, although undertaken by the state, from a federal excise tax upon its operations, upon what ground can it be said that the compensation of those who conduct the enterprise for the state is exempt from a federal income tax? Their compensation, whether paid out of the returns from the business or otherwise, can have no quality, so far as the federal taxing power is concerned, superior to that of the enterprise in which the compensated service is rendered. ”
