Westinghouse Electric Corp. v. Tully
Headline: New York’s tax credit for special export corporations struck down as discriminatory, barring the State from favoring in‑state shipping and affecting multistate exporters and state tax incentive design.
Holding: The method New York used to allow a tax credit for accumulated DISC income discriminates against interstate commerce by favoring in‑state shipments and therefore violates the Commerce Clause, so the Court reversed the state decision.
- Bars states from favoring in‑state shipping with tax credits.
- Makes multistate exporters face more uniform state tax treatment.
- Forces states to redesign discriminatory business tax incentives.
Summary
Background
A Pennsylvania manufacturer, Westinghouse, owned a Delaware export subsidiary that qualified as a special federal export entity (a DISC). New York required the parent to include the DISC’s accumulated income on a consolidated return but gave a 70% tax credit only for DISC receipts shipped from a New York place of business. New York’s tax agency assessed additional franchise tax, Westinghouse challenged the statute as unconstitutional, and the New York courts split before the state’s highest court upheld the tax credit.
Reasoning
The Supreme Court considered whether the way New York grants the DISC export credit treats out‑of‑state shipping worse than in‑state shipping. The Court explained that the State’s overall formula for apportioning taxable income was not the issue. Instead, the credit’s extra adjustment based on the percentage of a DISC’s shipments from New York duplicates and conflicts with the parent’s business allocation, producing a direct advantage for in‑state shipping. Relying on earlier decisions about state taxes that favor local activity, the Court concluded the credit discriminates against interstate commerce and violates the Commerce Clause, and it reversed the New York Court of Appeals.
Real world impact
The ruling prevents states from structuring tax credits that reward companies for shipping from in‑state locations while penalizing identical activity done from other States. Multistate exporters will face more uniform tax treatment across States, and states must redesign incentives that had favored in‑state shipping. The decision reverses the state court and declares New York’s credit unconstitutional under the Commerce Clause.
