For any partners not included in the amended California Nonresident Group Return, the amount reported to each partner shall be an adjustment to the partner’s share of partnership items as a result of the change or correction in subdivision (a) and each partner shall report any adjustments in accordance with Section 18622.

(e) Subject to the approval of the Franchise Tax Board, an audited partnership or tiered partner may enter into an alternative agreement with the Franchise Tax Board regarding any issue resulting from a federal audit adjustment, amended federal return, or administrative adjustment that would otherwise be subject to this section, including, but not limited to, the reporting and payment of tax, applicable time requirements, or any other provision that will provide, to the satisfaction of the Franchise Tax Board, for the reporting and payment of any taxes, penalties, and interest due pursuant to this section.

(2) If a partnership’s report of the California tax changes resulting from the adjustments filed pursuant to subdivision (a) results in an overstatement of California taxable or net income, the adjustment shall be applied as follows:

(A) If the original adjustments were passed through to the partners under paragraph (2) of subdivision (c), the revised adjustment shall be passed through to the partners. The partnership shall file or amend the return as described in subdivision (a).

(3) If properly reported and paid by the partnership or tiered partner, the amount determined in subparagraph (A) of paragraph (1) of subdivision (d) or similarly under an optional election, will be treated as paid in satisfaction of taxes owed by its direct and indirect partners on the same federal adjustments.

A publicly traded partnership shall be deemed to have made a federal election for alternative payment pursuant to Section 6226 of the Internal Revenue Code unless the publicly traded partnership files a request to make an election different from their federal election pursuant to paragraph (3) of subdivision (c).

(j) In order to reduce the administrative burden on taxpayers that may be imposed by additional filings and payments that do not contribute materially to revenue, the Franchise Tax Board shall convene a meeting or meetings of interested parties for the purpose of determining appropriate de minimis partner reporting and payment requirements as the result of a partnership level audit.

(k) (1) With respect to an action required or permitted to be taken by a partnership under this section and a proceeding under this part with respect to federal adjustments arising from a partnership level audit or an administrative adjustment request, the state partnership representative for the reviewed year shall have the sole authority to act on behalf of the partnership, and its partners and indirect partners shall be bound by those actions.

(2) The state partnership representative for the reviewed year is the partnership’s federal partnership representative, unless the partnership designates in writing another person as its state partnership representative.

(l) This section shall apply to final federal determinations assessed pursuant to amendments made to Subchapter C of Chapter 63 of the Internal Revenue Code as in effect January 1, 2018.
