The resulting ratio shall be known as the "administrative cost apportionment factor" and shall be multiplied by the sum of the property tax administrative costs incurred in the immediately preceding fiscal year by the assessor, tax collector, county board of equalization and assessment appeals boards, and auditor to determine the fiscal year property tax administrative costs proportionately attributable to each jurisdiction, ERAF, or community redevelopment agency. For purposes of this paragraph, property tax administrative costs shall also include applicable administrative overhead costs allowed by the federal Office of Management and Budget Circular A-87 standards, but shall not include any amount reimbursed pursuant to Section 75.60 and former Section 98.6, or include any amount in excess of the amounts reimbursable pursuant to Section 75.60, unless a county meets the conditions of paragraph (2) of subdivision (b) of Section 75.60. However, no amount of funds appropriated to counties for purposes of property tax administration in Item 9100-102-001 of the Budget Act of 1994 or any subsequent Budget Act shall result in any deduction from those property tax administrative costs that are eligible for reimbursement pursuant to this subdivision.
For purposes of applying this paragraph for the 1990-91 fiscal year, each proportionate share of property tax administrative costs shall be deducted from those amounts allocated to the relevant jurisdiction or community redevelopment agency after January 1, 1991.
