Harlan F. Stone,
Helvering v. Horst — Opinion of the Court
“ In the ordinary case the taxpayer who acquires the right to receive income is taxed when he receives it, regardless of the time when his right to receive payment accrued. But the rule that income is not taxable until realized has never been taken to mean that the taxpayer, even on the cash receipts basis, who has fully enjoyed the benefit of the economic gain represented by his right to receive income, can escape taxation because he has not himself received payment of it from his obligor. ”
