- Forces foreign parents to use state courts to challenge California tax calculations.
- Limits federal courts from blocking state tax assessment when state remedies exist.
- Encourages companies to pursue refunds and constitutional claims in state tax proceedings.
Summary
Background
A Canadian company and a British company sued California officials in federal court to stop the State’s way of computing how much of their U.S. subsidiaries’ income is taxed in California. The State uses a “unitary business/formula apportionment” method: it totals the earnings of a single business and assigns a share to California based on averaged ratios of payroll, property, and sales. The parents claimed that applying this method to their American subsidiaries improperly burdens foreign commerce and sought a federal declaration and injunction.
Reasoning
The Court assumed that the foreign parents had the basic constitutional interest to sue and that they could be treated as having shareholder standing to press the challenge. The key legal issue became the Tax Injunction Act, a federal law that prevents federal courts from stopping state tax assessment when a "plain, speedy and efficient" remedy exists in state courts. The Court concluded the Act applies here because the actual taxpayers are the U.S. subsidiaries, those subsidiaries can bring state-court challenges, and the foreign parents control those subsidiaries and therefore can press the same claims in state court. California courts appear likely to hear the parents’ foreign-commerce arguments, so federal intervention is barred.
Real world impact
As a result, foreign parent companies cannot bypass state procedures by suing in federal court when their controlled subsidiaries can challenge state tax assessments. The ruling limits federal courts’ ability to enjoin state tax collection in similar cases. This decision does not resolve whether California’s tax method violates the Constitution on the merits; if state courts refuse to hear the claims, the federal-bar answer might differ.
