I do not see a credit of this type specifically for Native
Americans in Oklahoma, also there are some other tax benefits affecting Native
Americans. For example, an employer in Oklahoma can get up to a $4,000 for
hiring a Native American. And I believe that Native Americans working on their
own tribal lands can get exemptions of income from state tax.
See Oklahoma Forms and
Instructions for the list of credits available on form 511CR starting on
page 8.
