Louis Brandeis, Welch v. Obispo Oil Company — Opinion of the Court
“ By the statute the amount of the income tax payable is dependent upon the amount of the profits tax; and the amount of the profits tax is dependent upon the amount of the income. In order to determine the corporate income tax payable at the statutory rate of 10 per cent., of the taxable net income, there must first be deducted from the net income the amount of the profits tax. ”
