Former Indian reservations in Oklahoma

These Oklahoma Tribal Statistical Areas are based on pre-statehood boundaries and may extend beyond the state border.

In 2017, the United States Court of Appeals for the Tenth Circuit ruled that the Muscogee (Creek) Nation reservation was never abolished by federal law.

In 2020, the United States Supreme Court ruled in McGirt v. Oklahoma that the land reserved for the Muscogee (Creek) Nation since the 19th century remains Indian country.

Congress tried to further rectify the situation through the Omnibus Budget Reconciliation Act of 1993, which authorized substantial tax incentives based on certain business activity within Indian reservations.

Government agencies are required to spend at least 3% of their budgets with prime contractors located in HUBZones.

The Department of Defense (DoD) Indian Incentive Program, part of the Office of Small Business, provides a 5% rebate to a prime contractor, based on the total amount subcontracted to an Indian-Owned Economic Enterprise or Indian Organization [11] To qualify, the organization must be at least 51% owned by an entity (or tribal member) of a federally recognized tribe.
