Stebbins v. Riley

Background

A California inheritance law adopted in 1917 forbids deducting any federal estate tax when determining the market value of property transferred for state tax purposes. The decedent left a gross estate exceeding $1,800,000; the federal estate tax on that estate was $128,730.08. Because the state tax appraiser did not subtract the federal tax, the state inheritance tax on the residuary estate was $26,205.75 higher than it would have been with the deduction. The state trial court and the California Supreme Court upheld the tax, and the case reached the United States Supreme Court.

Reasoning

The Court addressed whether the no-deduction rule was an arbitrary or unconstitutional discrimination that denied due process or equal protection. Petitioners argued that treating equal legacies differently depending on the size of the entire estate was unfair. The State argued that taxing the transfer or the privilege of receiving property at death falls within its power and that classifications related to estate size are permissible. The Court found the statute treats two elements of death transfers—the power to transfer and the privilege to inherit—and held that relying on both legacy size and total estate size is a reasonable classification. The Court affirmed the California courts and rejected the claim that this application of the tax was unconstitutional.

Real world impact

The decision allows California to calculate inheritance tax without deducting federal estate tax, meaning identical legacies can result in higher state taxes when they come from larger estates. People inheriting residuary legacies, estate administrators, and tax officials will be affected by this valuation rule. The Court treated the state law’s construction as binding, leaving the state taxing scheme operative.
