(1) The goals of the Legislative Assembly are to achieve for the people of this state a tax system that recognizes:
(a) Fairness and equity as its basic values; and
(b) That the total tax system should use seven guiding principles as measures by which to evaluate tax proposals.
(2) Those guiding principles are:
(a) Ability to pay;
(b) Fairness;
(c) Efficiency;
(d) Even distribution;
(e) The tax system should be equitable where the minimum aspects of a fair system are:
(A) That it shields genuine subsistence income from taxation;
(B) That it is not regressive; and
(C) That it imposes approximately the same tax burden on all households earning the same income;
(f) Adequacy; and
(g) Flexibility.
(3) To meet those goals of Oregon’s tax system, any tax must be considered in conjunction with the effects of all other taxes on Oregonians.
