Summary

Background

The dispute is between the Chickasaw Nation, a federally recognized Indian tribe, and the State of Oklahoma. The Tribe ran two convenience stores on tribal trust land and challenged Oklahoma's efforts to collect several state taxes. The two questions before the Court were whether Oklahoma could (1) apply its motor-fuels excise tax to fuel sold at the Tribe's stores in Indian country, and (2) tax income of tribal members who work for the Tribe but live elsewhere in Oklahoma.

Reasoning

On the fuel tax, the Court focused on who legally bears the tax's burden. It followed prior decisions that, absent clear congressional authorization, a State cannot enforce an excise tax whose legal incidence falls on a tribe or its members for sales inside Indian country. Because Oklahoma's statutes, as written and applied, placed the legal incidence on the retailer (here, the Tribe), the Court held the tax cannot be enforced on tribal retail sales in Indian country. On the income tax, the Court relied on the widely accepted rule that a state may tax the total income of its residents. The Treaty language protecting tribal self-government, the Court concluded, does not override a State's ordinary power to tax a resident's income earned from any source when the resident lives within the State outside Indian country.

Real world impact

Practically, Oklahoma may not collect its fuels excise tax as currently designed from the Tribe's sales on reservation land. At the same time, Oklahoma may tax the wages of tribal members who reside in the State off reservation lands, including wages from tribal employment. The opinion leaves open that a State could rewrite its tax law to shift legal incidence (for example, to consumers) or seek congressional authorization.

Dissents or concurrances

Justice Breyer, joined by three other Justices, would have barred Oklahoma from taxing wages of tribal members who work on tribal land but live off reservation, reading the Treaty as protecting such wages because the tax significantly affects tribal governance and members working within Indian country.
