Section 100.

Cal. Revenue and Taxation Code - RTC § 100.

in effect

Notwithstanding any other provision of law, commencing with the 1988–89 fiscal year, property tax assessed value attributable to unitary and operating nonunitary property, as defined in Sections 723 and 723.1, that is assessed by the State Board of Equalization shall be allocated by county as provided in Section 756, and the assessed value and revenues attributable to that allocation shall be allocated within each county as follows: (a) Each county shall establish one countywide tax rate area. The assessed value of all unitary and operating nonunitary property shall be assigned to this tax rate area. No other property shall be assigned to this tax rate area. (b) Property assigned to the tax rate area created by subdivision (a) shall be taxed at a rate equal to the sum of the following two rates: (1) A rate determined by dividing the county’s total ad valorem tax levies for the secured roll, including levies made pursuant to Section 96.8, for the prior year, exclusive of levies for debt service, by the county’s total ad valorem secured roll assessed value for the prior year. (2) A rate determined as follows: (A) By dividing the county’s total ad valorem tax levies for unitary and operating nonunitary property for the prior year debt service only by the county’s total unitary and operating nonunitary assessed value for the prior year. (B) Beginning with the 1989–90 fiscal year, adjusting the rate determined pursuant to subparagraph (A) by the percentage change between the two preceding fiscal years in the county’s ad valorem debt service levy for the secured roll, not including unitary and operating nonunitary debt service. (c) The property tax revenue derived from the assessed value assigned to the countywide tax rate area pursuant to subdivision (a) and pursuant to paragraph (2) of subdivision (a) of Section 100.1 by the use of the tax rate determined in paragraph (1) of subdivision (b) shall be allocated as follows: (1) For the 1988–89 fiscal year and each fiscal year thereafter, each taxing jurisdiction shall be allocated an amount of property tax revenue equal to 102 percent of the amount of the aggregate property tax revenue it received from all unitary and operating nonunitary property in the prior fiscal year, exclusive of revenue attributable to qualified property under Sections 100.95 and 100.96 and levies for debt service. (2) If the amount of property tax revenue available for allocation in the current fiscal year is insufficient to make the allocations required by paragraph (1), the amount of revenue to be allocated to each taxing jurisdiction shall be prorated based on a factor determined by dividing the total amount of property tax revenue available to all taxing jurisdictions from unitary and operating nonunitary property in the current year, exclusive of revenue attributable to levies for debt service, by the total amount of property tax revenue received by all taxing jurisdictions from unitary and operating nonunitary property in the prior fiscal year, exclusive of revenue attributable to levies for debt service. (3) If the amount of property tax revenue available for allocation to all taxing jurisdictions in the current fiscal year from unitary and operating nonunitary property, exclusive of revenue attributable to qualified property under Sections 100.95 and 100.96 and levies for debt service, exceeds 102 percent of the property tax revenue received by all taxing jurisdictions from all unitary and operating nonunitary property in the prior fiscal year, exclusive of revenue attributable to qualified property under Sections 100.95 and 100.96 and levies for debt service, the amount of revenue in excess of 102 percent shall be allocated to all taxing jurisdictions in the county by a ratio determined by dividing each taxing jurisdiction’s share of the county’s total ad valorem tax levies for the secured roll for the prior year, exclusive of levies for qualified property under Sections 100.95 and 100.96 and levies for debt service, by the county’s total ad valorem tax levies for the secured roll for the prior year, exclusive of levies for qualified property under Sections 100.95 and 100.96 and levies for debt service. (d) The property tax revenue derived from the assessed value assigned to the countywide tax rate area pursuant to subdivision (a) and pursuant to paragraph (2) of subdivision (a) of Section 100.1 by the use of the tax rate determined in paragraph (2) of subdivision (b) shall be allocated as follows: (1) An amount shall be computed for each taxing jurisdiction and shall be determined by multiplying the amounts required in the current year pursuant to subdivisions (a) and (c) of Section 93 by that percentage that shall be determined by dividing the amount of property tax revenue the jurisdiction received in the prior year from unitary property and operating nonunitary property by the total amount of property tax revenue the jurisdiction received in the prior year from all property. (2) The amount of property tax revenue available for allocation pursuant to this subdivision shall be allocated among taxing jurisdictions in the proportion that the amount computed for each taxing jurisdiction pursuant to paragraph (1) bears to the total amount computed pursuant to paragraph (1) for all taxing jurisdictions. (3) If a taxing jurisdiction is levying a tax rate for debt service for the first time in the current fiscal year, for purposes of determining the percentage specified in paragraph (1), that percentage shall be the percentage determined by dividing the amount of property tax revenue received by that taxing jurisdiction in the prior year pursuant to subdivision (c) from unitary and operating nonunitary property by the total amount of property tax revenue received by that taxing jurisdiction in the prior year from all property within the taxing jurisdiction. (e) For purposes of this section: (1) “The county’s total ad valorem tax levies for the secured roll” means all ad valorem tax levies for the county’s secured roll, including the general tax levy, levies for debt service (including land only and land and improvement rates), and levies for redevelopment agencies. (2) “The county’s total ad valorem secured roll” means the county’s local roll, after all exemptions except the homeowner’s exemption, and the county’s utility roll. (3) “Taxing jurisdiction” includes a redevelopment agency. (4) In a county of the second class, for the 1992–93 fiscal year and each fiscal year thereafter, “taxing jurisdiction” includes that fund that has been designated by the auditor as the “Unallocated Residual Public Utility Tax Fund.” All revenues allocated to that fund pursuant to this section shall be deposited in that fund and shall be distributed as follows: (A) For the 1992–93 fiscal year to the 1996–97 fiscal year, inclusive, at the discretion of the county board of supervisors. (B) For the 1997–98 fiscal year, 100 percent to the Orange County Fire Authority. (C) For the 1998–99 fiscal year and each fiscal year thereafter, in accordance with the following schedule: (i) Fifty-seven and forty-seven hundredths percent to the Orange County Fire Authority. (ii) Forty-one and forty-seven hundredths percent to the Orange County Library District. (iii) Forty-eight hundredths percent to the Buena Park Library District. (iv) Fifty-eight hundredths percent to the Placentia Library District. (f) The assessed value of the unitary and operating nonunitary property shall be kept separate for each state assessee throughout the allocation process. (g) Each state assessee shall be issued only one tax bill for all unitary and operating nonunitary property within the county. (h) This section applies to the unitary property of regulated railway companies only to the extent described in Section 100.1.

(2) The county auditor shall annually allocate to a city, county, or city and county, that has adopted and transmitted a resolution pursuant to paragraph (1), the amount of property tax revenues derived with respect to the property described in paragraph (1) that would be allocated to that city, county, or city and county if that property were subject to assessment by the county assessor. In order to provide the allocations required by this paragraph, the county auditor shall make any necessary pro rata reductions in allocations to local agencies other than that city, county, or city and county adopting and transmitting a resolution pursuant to paragraph (1), of property tax revenues derived with respect to the property described in paragraph (1).

(2) If the city, county, or city and county has adopted and transmitted a resolution pursuant to paragraph (1), the county auditor shall annually allocate the property tax revenue attributable to the new construction described in the development plan or agreement, as if that new construction were subject to assessment by the county assessor, according to the following formula: (A) An amount of property tax revenue to school entities, as defined in subdivision (f) of Section 95, equivalent to the same percentage the school entities received in the prior fiscal year of the property tax revenues paid by the utility in the county in which the property described in paragraph (1) is located. (B) An amount of property tax revenue to the county in which the property is located equivalent to the same percentage the county received in the prior fiscal year of the property tax revenues paid by the utility in the county in which the property described in paragraph (1) is located. The county shall distribute those property tax revenues to the county general fund, the county library district, the county flood control district, the county sanitation districts, and the county service areas.
