Cal. Gov. Code § 54902.1
In the event that any statement, map or plat required by this chapter is filed after the deadline specified in Section 54902, the provisions of Section 54903 shall apply to the territory described in such statement, map or plat and the boundary changes indicated therein shall not be effective for tax or assessment purposes for the fiscal year beginning on the following July 1.
Any city or district, or zone thereof, to which this section applies may borrow an amount of money equivalent to the anticipated tax revenue which would have been collected during such fiscal year within the territory described in the statement, map or plat, if such statement, map or plat had been filed on or before the deadline specified in Section 54902.
During succeeding fiscal years a tax or assessment may be levied by, or on behalf of, any city or district, or zone thereof, in order to repay such borrowed funds, including the cost of interest charges connected therewith. The tax shall be levied, after notice of the intent to levy the tax to the State Board of Equalization in such time and manner as prescribed by the board, only on that property described in the statement, map or plat. Such an amount of money may be raised during a single fiscal year or, at the discretion of the affected local agency, a portion of such amount may be raised in each of several fiscal years. The tax or assessment rate authorized by this section shall be in addition to any maximum property tax rate established pursuant to Chapter 3 (commencing with Section 2201) of Part 4 of Division 1 of the Revenue and Taxation Code.
