Superintendent of Five Civilized Tribes v. Commissioner

Background

Sandy Fox, a full-blood Creek Indian, had surplus funds from his restricted land allotment invested. The investment proceeds were collected and held in trust under the Secretary of the Interior. The question was whether those trust earnings were subject to the federal income tax created by the 1928 Revenue Act. The Commissioner, the Board of Tax Appeals, and the lower court all held the income was taxable; Fox argued he was exempt based on prior decisions and agreements involving Creek allotments.

Reasoning

The Court examined whether Congress clearly intended to exclude this kind of income. It relied on the broad language of the 1928 tax law and earlier decisions that treated wide tax language as covering most residents and income sources. The Court found no clear exemption in the Creek agreements of 1901–1902 or in the 1906 and 1908 Acts, which dealt mainly with land restrictions and homesteads rather than income from invested trust funds. The opinion emphasized that limits on selling land or wardship do not automatically create tax immunity, and noted the taxpayer was a United States citizen with only limited property control.

Real world impact

The ruling means that investment earnings held in trust for a restricted-allotment Indian are taxable federally unless Congress or a specific agreement clearly says otherwise. Indians with restricted allotments who receive trust investment income must treat that income as taxable under the federal law applied in this case. The Court affirmed the lower-court decision that such income is not exempt by implication.
