(a) Except as otherwise provided in Article 3 (commencing with Section 97), and in Article 4 (commencing with Section 98), for the 1980–81 fiscal year and each fiscal year thereafter, property tax revenues shall be apportioned to each jurisdiction pursuant to this section and Section 96.2 by the county auditor, subject to allocation and payment of funds as provided for in subdivision (b) of Section 33670 of the Health and Safety Code and subparagraph (D) of paragraph (3) of subdivision (g) of Section 53395.8 of the Government Code, to each jurisdiction in the following manner:

1. (1) For each tax rate area, each jurisdiction shall be allocated an amount of property tax revenue equal to the amount of property tax revenue allocated pursuant to this chapter to each jurisdiction in the prior fiscal year, modified by any adjustments required by Section 99 or 99.02.
2. (2) The difference between the total amount of property tax revenue and the amounts allocated pursuant to paragraph (1) shall be allocated pursuant to Section 96.5, and shall be known as the “annual tax increment.”
3. (3) For purposes of this section, the amount of property tax revenue referred to in paragraph (1) shall not include amounts generated by the increased assessments under Chapter 3.5 (commencing with Section 75).

(c)

1. (1) Guidelines for legislation implementation issued and determined necessary by the State Association of County Auditors, and when adopted as regulations by either the Controller or the Department of Finance pursuant to Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code, shall be considered an authoritative source deemed correct until some future clarification by legislation or court decision.
2. (2) If a county auditor knowingly does not follow the guidelines referred to in paragraph (1), that county auditor shall inform the Controller of the reason or reasons for not following the guidelines. If the Controller disagrees with the stated reason or reasons for not following the guidelines, the provisions of paragraph (3) do not apply.
3. (3) If, by audit begun on or after July 1, 2001, or discovery by an entity on or after July 1, 2001, it is determined that an allocation method is required to be adjusted and a reallocation is required for previous fiscal years, the cumulative reallocation or adjustment may not exceed 1 percent of the total amount levied at a 1-percent rate of the current year’s original secured tax roll. The reallocation shall be completed in equal increments within the following three fiscal years, or as negotiated with the Controller in the case of reallocation to the Educational Revenue Augmentation Fund or school entities.
4. (4) If it is determined that an allocation method is required to be adjusted as provided in paragraph (3), the county auditor shall, in the fiscal year following the fiscal year in which this determination is made, correct the allocation method in accordance with statute.
