(1) Introduction. This rule explains how a taxing district restores a regular property tax levy if it has not levied ((since 1985))for the last seven calendar years and it elects to restore a regular property tax levy in accordance with RCW 84.55.015.

(2) Calculation of restored regular levy.

(a) If a taxing district has not levied ((since 1985))for the last seven calendar years and it elects to restore a regular property tax levy, then the amount of the first ((regular property tax payable as a result of the restored levy cannot exceed the lesser of:

The levy rate that is proposed to be restored is determined by dividing the total dollar amount that was last levied by the district by the current year's assessed value after deducting the accumulated assessed values attributable to (A) through (D) of this subsection))restored levy must result in a tax rate that does not exceed the statutory rate limit applicable to the taxing district's regular property tax levy; or

(b) ((The maximum amount which could be lawfully levied by that district in the year the restored levy is proposed, subject to the statutory dollar rate limit contained in the taxing district's authorizing statute, without considering the calculation used in subsection (2)(a) of this rule))If a taxing district has not levied for the last six or fewer calendar years and elects to restore a regular property tax levy, then the first restored levy must not exceed the maximum levy amount allowed by the levy limit that would have been imposed had the taxing district continuously levied.

(3) Example. Taxing district "A" has not levied a regular levy ((since 1985))in over 20 years when it levied $10,000 based upon ((1985))1999 assessed values and all lawful limitations at that time. ((The total increase since the 1985 assessment year in assessed value of property in the district as a result of new construction, improvements to property, increases in the assessed value of state assessed property, and increases in assessed value due to the construction of wind turbine, solar, biomass, and geothermal facilities beginning in 1986 through the current assessment year is $3,000,000. The assessed value of taxing district "A" for the current year is $15,000,000. The calculation for subsection (2)(a) of this rule is as follows:

(4) Assessor to maintain taxing district records. Records of value increases attributable to new construction, improvements to property, increases in the assessed value of state assessed property, and increases in assessed value due to the construction of wind turbine, solar, biomass, and geothermal facilities are to be maintained each year by the county assessor for each taxing district whether or not the district imposes a regular property tax levy.))Because taxing district "A" has not levied regular property taxes in more than seven calendar years, its first restored levy may not exceed the statutory maximum dollar rate limit applicable to taxing district "A," multiplied by taxing district's "A" total assessed value.

(1) Introduction. This rule describes the process used to reduce or eliminate a levy rate when the assessor finds the statutory aggregate dollar rate limit exceeds $5.90. The aggregate of all regular levy rates of junior taxing districts and senior taxing districts, other than the state and other specifically identified districts, cannot exceed $5.90 per $1,000 of assessed value in accordance with RCW 84.52.043. When the county assessor finds that this limit has been exceeded, the assessor recalculates the levy rates and establishes a new consolidated levy rate as described in RCW 84.52.010. The $5.90 statutory aggregate dollar rate limit is reviewed before the constitutional one percent limit.

(2) Levies not subject to statutory aggregate dollar rate limit. The following levies are not subject to the statutory aggregate dollar rate limit of $5.90 per $1,000 of assessed value:

(a) Levies by the state;

(b) Levies by or for port or public utility districts;

(c) Excess property tax levies authorized in Article VII, section 2 of the state Constitution;

(d) Levies by or for county ferry districts under RCW 36.54.130;

(e) Levies for acquiring conservation futures under RCW 84.34.230;

(f) Levies for emergency medical care or emergency medical services under RCW 84.52.069;

(g) Levies for financing affordable housing under RCW 84.52.105;

(h) The portion of metropolitan park district levies protected under RCW 84.52.120;

(i) The portions of levies by fire protection districts and regional fire protection service authorities protected under RCW 84.52.125;

(j) Levies for criminal justice purposes under RCW 84.52.135;

(k) Levies for transit-related purposes by a county under RCW 84.52.140;

(l) The protected portion of the levies imposed under RCW 84.52.816 by flood control zone districts;

(m) Levies imposed by a regional transit authority under RCW 81.104.175; ((and))

(n) Levies imposed under RCW 36.69.145, by a park and recreation district located on an island and within a county with a population exceeding 2,000,000, for collection in calendar years 2022 through 2026; and

(o) The portion of any levy resulting from the correction of a levy error under RCW 84.52.085(3).

(3) Consolidated levy rate limitation. RCW 84.52.010 explains the order in which the regular levies of taxing districts will be reduced or eliminated by the assessor to comply with the statutory aggregate dollar rate limit of $5.90 per $1,000 of assessed value. The order in the statute lists which taxing districts are the first to either reduce or eliminate their levy rate. Taxing districts that are at the same level are grouped together in tiers. Reductions or eliminations in levy rates are made on a pro rata basis within each tier of taxing district levies until the consolidated levy rate no longer exceeds the statutory aggregate dollar rate limit of $5.90.

As opposed to the order in RCW 84.52.010, which lists the taxing districts that are the first to have their levy rates reduced or eliminated, this rule is written in reverse order; that is, it lists the taxing districts that must be first either fully or partially funded. If the statutory aggregate dollar rate is exceeded, then the levy rates for taxing districts within a particular tier must be reduced or eliminated on a pro rata basis. The proration factor, which is multiplied by each levy rate within the tier, is obtained by dividing the dollar rate remaining available to the taxing districts in that tier as a group by the sum of the levy rates originally certified by or for all of the taxing districts within the tier.

(a) Step one: Total the aggregate regular levy rates requested by all affected taxing districts in the tax code area. If this total is less than $5.90 per $1,000 of assessed value, no levy rate reduction or elimination is necessary. If this total levy rate is more than $5.90, the assessor must proceed through the following steps until the aggregate dollar rate is brought within that limit.

(b) Step two: Subtract from $5.90 the levy rates of the county, including the rate of any separate property tax levy as described in RCW 84.55.135, and the county road district if the tax code area includes an unincorporated portion of the county, or the levy rates of the county and the city or town if the tax code area includes an incorporated area, as applicable.

(c) Step three: Subtract from the remaining levy capacity the levy rates, if any, for fire protection districts under RCW 52.16.130, regional fire protection service authorities under RCW 52.26.140 (1)(a), library districts under RCW 27.12.050 and 27.12.150, the first 50 cents per $1,000 of assessed value for metropolitan park districts created before January 1, 2002, under RCW 35.61.210, and the first 50 cents per $1,000 of assessed value for public hospital districts under RCW 70.44.060(6).

(i) If the balance is zero, there is no remaining levy capacity for any other junior taxing district at a lower tier and their levies, if any, must be eliminated.

(ii) If the balance is less than zero, then the levies within this tier must be reduced on a pro rata basis until the balance is zero. After prorationing, there is no remaining levy capacity for any other junior taxing districts at a lower tier and their levies, if any, must be eliminated.

(iii) If the remaining balance is greater than zero, this amount is available to the remaining junior taxing districts at a lower tier and the assessor should proceed on to step four.

(d) Step four: Subtract from the remaining levy capacity the levy rates, if any, for fire protection districts under RCW 52.16.140 and 52.16.160, and regional fire protection service authorities under RCW 52.26.140 (1)(b) and (c). However, under RCW 84.52.125, a fire protection district or regional fire protection service authority may protect up to 25 cents per $1,000 of assessed value of the total levies made under RCW 52.16.140 and 52.16.160, or 52.26.140 (1)(b) and (c) from reduction or elimination.

(i) If the balance is zero, there is no remaining levy capacity for any other junior taxing districts at a lower tier and their levies, if any, must be eliminated.

(ii) If the balance is less than zero, then the levies within this tier must be reduced on a pro rata basis until the balance is zero. It is at this point that the provisions of RCW 84.52.125 come into play; that is, a fire protection district or regional fire protection service authority may protect up to 25 cents per $1,000 of assessed value of the total levies made under RCW 52.16.140 and 52.16.160, or 52.26.140 (1)(b) and (c) from reduction or elimination under RCW 84.52.043(2), if the total levies would otherwise be reduced or eliminated under RCW 84.52.010 (3)(a)(iii) with respect to the $5.90 per $1,000 of assessed value limit. After prorationing, there is no remaining levy capacity for any other junior taxing district at a lower tier and their levies, if any, must be eliminated.

(iii) If the remaining balance is greater than zero, this amount is available to the remaining junior taxing districts at a lower tier and the assessor should proceed on to step five.

(e) Step five: Subtract from the remaining levy capacity the levy rate, if any, for the first 50 cents per $1,000 of assessed value of metropolitan park districts created on or after January 1, 2002, under RCW 35.61.210.

(i) If the balance is zero, there is no remaining levy capacity for any other junior taxing districts at a lower tier and their levies, if any, must be eliminated.

(ii) If the balance is less than zero, then the levies within this tier must be reduced on a pro rata basis until the balance is zero. After prorationing, there is no remaining levy capacity for any other junior taxing district at a lower tier and their levies, if any, must be eliminated.

(iii) If the remaining balance is greater than zero, this amount is available to the remaining junior taxing districts at a lower tier and the assessor should proceed on to step six.

(f) Step six: Subtract from the remaining levy capacity the 25 cent per $1,000 of assessed value levy rate for metropolitan park districts if it is not protected under RCW 84.52.120, the 25 cent per $1,000 of assessed value levy rate for public hospital districts under RCW 70.44.060(6), and the levy rates, if any, for cemetery districts under RCW 68.52.310 and all other junior taxing districts if those levies are not listed in steps three through five or seven or eight of this subsection.

(i) If the balance is zero, there is no remaining levy capacity for any other junior taxing districts at a lower tier and their levies, if any, must be eliminated.

(ii) If the balance is less than zero, then the levies within this tier must be reduced on a pro rata basis until the balance is zero. After prorationing, there is no remaining levy capacity for any other junior taxing district at a lower tier and their levies, if any, must be eliminated.

(iii) If the remaining balance is greater than zero, this amount is available to the remaining junior taxing districts at a lower tier and the assessor should proceed on to step seven.

(g) Step seven: Subtract from the remaining levy capacity the levy rate, if any, for flood control zone districts other than the portion of a levy protected under RCW 84.52.816.

(i) If the balance is zero, there is no remaining levy capacity for any other junior taxing districts at a lower tier and their levies, if any, must be eliminated.

(ii) If the balance is less than zero, then the levies within this tier must be reduced on a pro rata basis until the balance is zero. After prorationing, there is no remaining levy capacity for any other junior taxing district at a lower tier and their levies, if any, must be eliminated.

(iii) If the remaining balance is greater than zero, this amount is available to the remaining junior taxing districts at a lower tier and the assessor should proceed on to step eight.

(h) Step eight: Subtract from the remaining levy capacity the levy rates, if any, for city transportation authorities under RCW 35.95A.100, park and recreation service areas under RCW 36.68.525, park and recreation districts under RCW 36.69.145, except a park and recreation district described in subsection (2)(n) of this rule, and cultural arts, stadium, and convention districts under RCW 67.38.130.

(i) If the balance is zero, there is no remaining levy capacity for other junior taxing districts at a lower tier and their levies, if any, must be eliminated.

(ii) If the balance is less than zero, then the levies within this tier must be reduced on a pro rata basis until the balance is zero. After prorationing, there is no remaining levy capacity for any other junior taxing district at a lower tier and their levies, if any, must be eliminated.

(iii) If the remaining balance is greater than zero, this amount is available to the remaining junior taxing districts at a lower tier and the assessor should proceed on to step nine.

(i) Step nine: Subtract from the remaining levy capacity the levy imposed, if any, for cultural access programs under RCW 36.160.080 until the remaining levy capacity equals zero.

(4) Example.

(a) Beginning with the limit of $5.90, subtract the original certified levy rates for the county and county road taxing districts leaving $1.85 available for the remaining districts.

(b) Subtract the total of the levy rates for each district within the next tier: The library's $.50, the fire district's $.50 and the hospital's $.50 = $1.50, which leaves $.35 available for the remaining districts.

(c) Subtract the fire district's additional $.20 levy rate, which leaves $.15 available for the remaining districts.

(d) The remaining $.15 must be shared by the cemetery and the hospital districts within the next tier of levies. The cemetery district originally sought to levy $.1125 and the hospital district sought to levy $.25. The proration factor is arrived at by dividing the amount available ($.15) by the original levy rates ($.3625) requested within that tier resulting in a proration factor of .4138. Finally, the original levy rates in this tier of $.1125 and $.25 for the cemetery and hospital, respectively, are multiplied by the proration factor.

(1) Introduction. This rule explains how to determine if the constitutional one percent limit is being exceeded and the sequence in which levy rates will be reduced or eliminated in accordance with RCW 84.52.010 if the constitutional one percent limit is exceeded. The constitutional one percent calculation is made after the assessor ensures that the $5.90 statutory aggregate dollar rate limit is not exceeded. The total amount of all regular property tax levies that can be applied against taxable property is limited to one percent of the true and fair value of the property in money. The one percent limit is stated in Article VII, section 2 of the state Constitution and the enabling statute, RCW 84.52.050. The constitutional one percent limit is based on the amount of taxes actually levied on the true and fair value of the property, not the dollar rate used in calculating property taxes.

(2) Preliminary calculations. After reducing or eliminating the levy rates under RCW 84.52.043 (the $5.90 statutory aggregate dollar rate limit) has occurred, make the following calculations to determine if the constitutional one percent limit is being exceeded:

(a) First, add together all regular levy rates in the tax code area, including the rates for the state levy, but not the rates for port and public utility districts, to arrive at a combined levy rate for that tax code area. "Regular levy rates" in this context means the levy rates that remain after reduction or elimination under RCW 84.52.043 has occurred. The levy rates for port and public utility districts are not included in this calculation because they are not subject to the constitutional one percent limit.

(b) Second, divide $10 by the higher of the real or personal property ratio of the county for the assessment year in which the levy is made to determine the maximum effective levy rate. If the combined levy rate exceeds the maximum effective levy rate, then the individual levy rates must be reduced or eliminated until the combined levy rate is equal to the maximum effective levy rate.

(3) Constitutional one percent limit. RCW 84.52.010 provides the order in which levy rates are to be reduced or eliminated when the constitutional one percent limit is exceeded.

As opposed to the order in RCW 84.52.010, which lists the taxing districts that are the first to have their levy rates reduced or eliminated, this rule is written in reverse order; that is, it lists the taxing districts that must be first either fully or partially funded. If the constitutional one percent limit is exceeded, then the levy rates for taxing districts within a particular tier must be reduced or eliminated on a pro rata basis.

If the constitutional one percent limit is exceeded after performing the preliminary calculations described in subsection (2) of this rule, the following levies must be reduced or eliminated until the combined levy rate no longer exceeds the maximum effective levy rate:

(a) Step one: Subtract the aggregate levy rate calculated for the state for the support of common schools from the effective rate limit.

(b) Step two: Subtract the levy rates for the county, including the rate of any separate property tax levy as described in RCW 84.55.135, county road district, regional transit authority, and for city or town purposes.

(c) Step three: Subtract from the remaining levy capacity the levy rates for fire protection districts under RCW 52.16.130, regional fire protection service authorities under RCW 52.26.140 (1)(a), library districts under RCW 27.12.050 and 27.12.150, the first 50 cents per $1,000 of assessed value for metropolitan park districts created before January 1, 2002, under RCW 35.61.210, and the first 50 cents per $1,000 of assessed value for public hospital districts under RCW 70.44.060(6).

(i) If the balance is zero, there is no remaining levy capacity for any other junior taxing district at a lower tier and their levies, if any, must be eliminated.

(ii) If the balance is less than zero, then the levies within this tier must be reduced on a pro rata basis from the remaining balance in step two until the balance is zero. After prorationing, there is no remaining levy capacity for any other junior taxing districts at a lower tier and their levies, if any, must be eliminated.

(iii) If the remaining balance is greater than zero, this amount is available to the remaining junior taxing districts at a lower tier and the assessor should proceed on to step four.

(d) Step four: Subtract from the remaining levy capacity the levy rates for fire protection districts under RCW 52.16.140 and 52.16.160, and regional fire protection service authorities under RCW 52.26.140 (1)(b) and (c).

(i) If the balance is zero, there is no remaining levy capacity for any other junior taxing districts at a lower tier and their levies, if any, must be eliminated.

(ii) If the balance is less than zero, then the levies within this tier must be reduced on a pro rata basis from the remaining balance in step three until the balance is zero. After prorationing, there is no remaining levy capacity for any other junior taxing district at a lower tier and their levies, if any, must be eliminated.

(iii) If the remaining balance is greater than zero, this amount is available to the remaining junior taxing districts at a lower tier and the assessor should proceed on to step five.

(e) Step five: Subtract from the remaining levy capacity the levy rate for the first 50 cents per $1,000 of assessed value of metropolitan park districts created on or after January 1, 2002, under RCW 35.61.210.

(ii) If the balance is less than zero, then the levy is reduced to the remaining balance in step four. There is no remaining levy capacity for any other junior taxing district at a lower tier and their levies, if any, must be eliminated.

(iii) If the remaining balance is greater than zero, this amount is available to the remaining junior taxing districts at a lower tier and the assessor should proceed on to step six.
