Section 310.222 - Computation of 1997 Measure 50 reduction and supplemental statutory reduction; certification to assessor.

(a) A statewide constitutional reduction percentage for pre-reduction Measure 50 taxes so as to achieve a statewide average reduction in Measure 50 taxes of 17 percent; and
(b) A supplemental statutory reduction percentage so as to achieve a statewide average reduction of 17 percent in all of the following taxes:
(A) Pre-reduction Measure 50 taxes;
(B) Taxes used to pay qualified obligations of the taxing districts, if the qualified obligations consist of local government pension and disability plan obligations;
(C) Urban renewal taxes other than urban renewal taxes used to pay principal and interest on bonded indebtedness; and
(D) An operating tax levy approved by voters prior to December 5, 1996, and for which property taxes are first imposed for the tax year beginning July 1, 1996, or July 1, 1997, if the levy was approved by voters in an election:
(i) In which at least 50 percent of registered voters eligible to vote in the election cast a ballot; or
(ii) That was the general election in an even-numbered year.
(2) The department shall compute a constitutional reduction percentage for Measure 50 taxes by comparing the total statewide pre-reduction Measure 50 tax amount with the total statewide Measure 47 comparison tax amount and calculating the statewide percentage by which the total Measure 47 comparison tax amount is less than the total pre-reduction Measure 50 tax amount.
(3) If the statewide reduction percentage for Measure 50 taxes determined under subsection (1) of this section equals 17 percent, the constitutional reduction percentage for each district shall equal the percentage certified to the district under ORS 310.220. The department shall proceed to calculate the supplemental statutory reduction under subsection (6) of this section.
(4) If the statewide reduction percentage for Measure 50 taxes determined under subsection (1) of this section is greater than 17 percent, each taxing district’s preliminary reduction percentage shall be multiplied by a fraction, the numerator of which is the percentage point difference between the statewide reduction percentage and 17 percent, and the denominator of which is the statewide reduction percentage. The product shall then be subtracted from the preliminary reduction percentage to obtain the taxing district’s constitutional reduction percentage. The department shall then calculate the supplemental statutory reduction under subsection (6) of this section.
(5) If the statewide reduction percentage for Measure 50 taxes determined under subsection (1) of this section is less than 17 percent, each taxing district’s preliminary reduction percentage shall be multiplied by a fraction, the numerator of which is the percentage point difference between the statewide reduction percentage and 17 percent, and the denominator of which is the statewide reduction percentage. The product shall then be added to the preliminary reduction percentage to obtain the constitutional reduction percentage for the district. The department shall then calculate the supplemental statutory reduction under subsection (6) of this section.
(6)(a) Following the determination made under subsection (3), (4) or (5) of this section, the department shall compute a supplemental statutory reduction percentage so that the statewide total amount of all of the taxes described in subsection (1)(b) of this section is reduced by 17 percent, using the procedure in this subsection.
(b) The department shall compute a statewide total amount of the taxes certified under ORS 310.220 (6), (7) and (8), and shall multiply this amount by 17 percent.
(c) The supplemental reduction shall be the percentage equivalent of a fraction, the numerator of which is the amount calculated under paragraph (b) of this section and the denominator of which is the statewide total pre-reduction Measure 50 tax amount plus the total amount of taxes certified under ORS 310.220 (6), (7) and (8).
(d) For each taxing district, the department shall:
(A) Add the supplemental reduction percentage to the constitutional reduction percentage determined for the district under subsection (3), (4) or (5) of this section to determine a total reduction percentage for taxes that are subject to constitutional reduction; and
(B) Reduce the district’s other taxes that were certified by the assessor under ORS 310.220 (6), (7) and (8) by the supplemental statutory reduction percentage.
(7)(a) If the statewide constitutional reduction percentage no longer equals 17 percent after the department estimates compression of Measure 50 taxes on a code area basis, the department shall recalculate the constitutional reduction percentages as described in subsections (4) and (5) of this section until the statewide reduction percentage equals 17 percent. Constitutional reduction percentages for each district shall be finally determined prior to any determination of supplemental statutory reduction.
(b) The reduction percentages determined under this section shall be adjusted so that the appropriate pre-compression rate is the rate used under ORS 310.236.
(8) The department shall certify to the assessor:
(a) The constitutional reduction percentages and reduction amounts for each district as determined under subsections (3), (4) and (5) of this section; and
(b) The statutory reduction percentages and reduction amounts determined under subsection (6) of this section. [1997 c.541 §29]
