ORS § 285C.303
The Legislative Assembly finds that the welfare of the residents of the rural Indian reservations of this state is acutely dependent upon the growth, development and expansion of employment and business opportunities within reservation boundaries. Geographic and other obstacles have made it difficult for rural Indian reservations to attract and retain private business investment. The tax systems of this state, by subjecting businesses located within reservation boundaries to state taxation in addition to any taxation imposed by the reservations themselves, has heightened the economic isolation of this state's rural reservations and impeded the efforts of Indian tribes to develop sufficient tax bases to fund essential governmental services on their reservations. The Legislative Assembly further finds that it is in the best interests of this state to create equality that will enable rural Indian reservations to attract and retain private business investment. The Legislative Assembly declares that it is the purpose of ORS 285C. 300 to 285C. 320 to remove the tax disincentives that currently inhibit private business and industry from locating and operating enterprises within the boundaries of the rural Indian reservations of this state.
