Owen J. Roberts, Helvering v. Bruun — Opinion of the Court
“ While it is true that economic gain is not always taxable as income, it is settled that the realization of gain need not be in cash derived from the sale of an asset. Gain may occur as a result of exchange of property, payment of the taxpayer's indebtedness, relief from a liability, or other profit realized from the completion of a transaction. [9] The fact that the gain is a portion of the value of property received by the taxpayer in the transaction does not negative its realization. ”
