Cal. EDC § 16081

Notwithstanding any provision of law to the contrary, whenever in any fiscal year, pursuant to Chapter 5 (commencing with Section 5096), Part 9, Division 1 of the Revenue and Taxation Code, a refund is made or a judgment rendered, as the case may be, for the return of an amount collected as school district taxes levied during a previous year upon secured or unsecured personal property, because it was determined that such property was exempt from taxation, and such property so determined to be exempt equals 1 percent, or more, of the assessed valuation in the school district upon which school district taxes for such previous year were levied, the Controller shall reduce the annual repayment of the district and the amount deducted from the State School Fund apportionment of such district for the fiscal year next succeeding that in which such refund was made or judgment rendered, by that amount by which the annual repayment and deduction of the district would have been reduced for the fiscal year next succeeding that in which such taxes were levied had the assessed valuation upon which such annual repayment was computed not included an amount of assessed valuation equal to the amount of assessed valuation of the property so determined to be exempt.

The amount of annual repayment and deduction, reduced as required by this section, shall be the amount deducted by the Controller for the purposes of Sections 16080, 16089 and 16090 for the fiscal year in which such reduction is made.
