Case Brief Summary & Legal Analysis
tl;dr: The Supreme Court upheld Iowa’s single-factor sales formula for apportioning corporate income tax, finding it did not violate the Due Process or Commerce Clauses, even though it differed from the three-factor formula used by most states and created a risk of duplicative taxation.
Legal Significance: This case establishes that states have wide latitude in choosing income apportionment formulas. The Court will not mandate national uniformity under the Commerce Clause, deferring that power to Congress, and will only invalidate a formula on Due Process grounds if it produces a grossly distorted result.

Case Facts & Court Holding
Key Facts & Case Background
Moorman Manufacturing Co., an Illinois corporation, manufactured animal feeds in Illinois and sold them in Iowa, where it maintained salesmen and warehouses. Iowa taxed the income of interstate corporations using a single-factor apportionment formula based solely on the percentage of a company’s total sales that occurred in Iowa. Moorman, whose Iowa sales were about 20% of its total, argued this formula was unconstitutional. Illinois and most other states used a three-factor formula, which equally weighed property, payroll, and sales. Moorman contended that Iowa’s formula taxed income generated by its manufacturing activities in Illinois, violating the Due Process Clause. It also argued that the discrepancy between Iowa’s formula and the prevalent three-factor formula resulted in duplicative taxation and discriminated against interstate commerce, violating the Commerce Clause. Moorman did not, however, provide a separate accounting analysis to prove the precise amount of income generated by its out-of-state activities.
