Section 18633.5.

(a) Every limited liability company which is classified as a partnership for California tax purposes that is doing business in this state, organized in this state, or registered with the Secretary of State shall file its return on or before the fifteenth day of the fourth month following the close of its taxable year, stating specifically the items of gross income and the deductions allowed by Part 10 (commencing with Section 17001). The return shall include the names, addresses, and taxpayer identification numbers of the persons, whether residents or nonresidents, who would be entitled to share in the net income if distributed and the amount of the distributive share of each person. The return shall contain or be verified by a written declaration that it is made under penalty of perjury, signed by one of the limited liability company members. In the case of a limited liability company not doing business in this state, and subject to the tax imposed by subdivision (b) of Section 17941, the Franchise Tax Board shall, for returns required to be filed on or after January 1, 1998, prescribe the manner and extent to which the information identified in this subdivision shall be included with the return required by this subdivision.

(b) Each limited liability company required to file a return under subdivision (a) for any limited liability company taxable year shall, on or before the day on which the return for that taxable year was required to be filed, furnish to each person who holds an interest in that limited liability company at any time during that taxable year a copy of that information required to be shown on that return as may be required by forms and instructions prescribed by the Franchise Tax Board.

(c) Any person who holds an interest in a limited liability company as a nominee for another person shall do both of the following:

(1) Furnish to the limited liability company, in the manner prescribed by the Franchise Tax Board, the name, address, and taxpayer identification number of that person, and any other information for that taxable year as the Franchise Tax Board may prescribe by forms and instructions.

(2) Furnish to that other person, in the manner prescribed by the Franchise Tax Board, the information provided by that limited liability company under subdivision (b).

(d) The provisions of Section 6031(d) of the Internal Revenue Code, relating to the separate statement of items of unrelated business taxable income, shall apply.

(e) (1) A limited liability company shall file with its return required under subdivision (a), in the form required by the Franchise Tax Board, the agreement of each nonresident member to file a return pursuant to Section 18501, to make timely payment of all taxes imposed on the member by this state with respect to the income of the limited liability company, and to be subject to personal jurisdiction in this state for purposes of the collection of income taxes, together with related interest and penalties, imposed on the member by this state with respect to the income of the limited liability company. If the limited liability company fails to timely file the agreements on behalf of each of its nonresident members, then the limited liability company shall, at the time set forth in subdivision (f), pay to this state on behalf of each nonresident member of whom an agreement has not been timely filed an amount equal to the highest marginal tax rate in effect under Section 17041, in the case of members which are individuals, estates, or trusts, and Section 23151, in the case of members that are corporations, multiplied by the amount of the member's distributive share of the income source to the state reflected on the limited liability company's return for the taxable period, reduced by the amount of tax previously withheld and paid by the limited liability company pursuant to Section 18662 and the regulations thereunder with respect to each nonresident member. A limited liability company shall be entitled to recover the payment made from the member on whose behalf the payment was made.

(2) If a limited liability company fails to attach the agreement or to timely pay the payment required by paragraph (1), the payment shall be considered the tax of the limited liability company for purposes of the penalty prescribed by Section 19132 and interest prescribed by Section 19101 for failure to timely pay the tax. Payment of the penalty and interest imposed on the limited liability company for failure to timely pay the amount required by this subdivision shall extinguish the liability of a nonresident member for the penalty and interest for failure to make timely payment of all taxes imposed on that member by this state with respect to the income of the limited liability company.

(3) No penalty or interest shall be imposed on the limited liability company under paragraph (2) if the nonresident member timely files and pays all taxes imposed on the member by this state with respect to the income of the limited liability company.

(f) Any agreement of a nonresident member required to be filed pursuant to subdivision (e) shall be filed at either of the following times:

(1) The time the annual return is required to be filed pursuant to this section for the first taxable period for which the limited liability company became subject to tax pursuant to Chapter 10.6 (commencing with Section 17941).

(2) The time the annual return is required to be filed pursuant to this section for any taxable period in which the limited liability company had a nonresident member on whose behalf an agreement described in subdivision (e) has not been previously filed.

(g) Any amount paid by the limited liability company to this state pursuant to paragraph (1) of subdivision (e) shall be considered to be a payment by the member on account of the income tax imposed by this state on the member for the taxable period.

(h) Every limited liability company that is classified as a corporation for California tax purposes shall be subject to the requirement to file a tax return under the provisions of Part 10.2 (commencing with Section 18401) and the applicable taxes imposed by Part 11 (commencing with Section 23001).

(i) (1) Every limited liability company doing business in this state, organized in this state, or registered with the Secretary of State, that is disregarded pursuant to Section 23038 shall file a return that includes information necessary to verify its liability under Sections 17941 and 17942, provides its sole owner's name and taxpayer identification number, includes the consent of the owner to California tax jurisdiction, and includes other information necessary for the administration of this part, Part 10 (commencing with Section 17001), or Part 11 (commencing with Section 23001).

(2) If the owner's consent required under paragraph (1) is not included, the limited liability company shall pay on behalf of its owner an amount consistent with, and treated the same as, the amount to be paid under subdivision (e) by a limited liability company on behalf of a nonresident member for whom an agreement required by subdivision (e) is not attached to the return of the limited liability company.

(3) The return required under paragraph (1) shall be filed on or before the fifteenth day of the fourth month after the close of the taxable year of the owner subject to tax under Part 10 (commencing with Section 17001) of Division 2 or on or before the fifteenth day of the third month after the close of the taxable year of the owner subject to tax under Chapter 2 (commencing with Section 23101) of Part 11 of Division 2, whichever is applicable.

(4) For limited liability companies disregarded pursuant to Section 23038, "taxable year of the owner" shall be substituted for "taxable year" in Sections 17941 and 17942.

(j) The amendments made by the act adding this subdivision apply to taxable years beginning on or after January 1, 2005.

(Amended by Stats. 2005, Ch. 264, Sec. 15. Effective January 1, 2006.)
