Article VIII: taxation and revenue
Section 1

B. The legislature shall provide by law for the valuation of residential property for property taxation purposes in a manner that limits annual increases in valuation of residential property. The limitation may be applied to classes of residential property taxpayers based on owner-occupancy, age or income. The limitations may be authorized statewide or at the option of a local jurisdiction and may include conditions under which the limitation is applied. Any valuation limitations authorized as a local jurisdiction option shall provide for applying statewide or multi-jurisdictional property tax rates to the value of the property as if the valuation increase limitation did not apply.
