How Donnelly v. United States applies in California: state-specific rules, key cases, and bar exam notes for Tax Law.
In California, tax law principles relating to deductions and income recognition generally align with the rationale established in Donnelly v. United States.

California adopts a 'substance over form' approach, where the actual economic reality of transactions dictates tax treatment, similar to the doctrine in Donnelly.

This case clarified that timing of income recognition must reflect genuine transactions rather than mere formalities.

California's tax law principles echo those at the federal level, particularly around the substantiation of deductions. However, California may impose additional criteria on taxpayers, reflecting its distinct policy priorities.
