Scott A. Taylor (University of St. Thomas) has published Taxation in Indian Country After Carcieri v. Salazar, 36  Wm. Mitchell L. Rev. 590 (2010).  Here is the abstract:

Federally recognized Indian tribes are governments within our federal legal system. Tribes have aboriginal sovereignty that provides them with inherent governmental powers, such as the power to tax. Tribal sovereignty also protects tribes from state interference, such as state taxation of tribal lands. Both the exercise of tribal governmental powers and the tribal immunity from state interference have a territorial component. This makes the status of Indian lands a critical inquiry into tribal/state relations. Because of the importance of land status in federal Indian law, especially in matters involving taxation, the decision of the United States Supreme Court in Carcieri v. Salazar deserves special attention. In the Carcieri case, the Court held that the Secretary of the Interior did not have the statutory authority to place lands into trust on behalf of Indian tribes that were recognized after the enactment of the Indian Reorganization Act of 1934. This article explores taxation in Indian Country after Carcieri.
