(5) Failure of audited partnership or tiered partner to report or pay. Nothing in this subsection is intended to prevent the commissioner from assessing direct partners and indirect partners for taxes they owe in the event that an audited partnership or tiered partner fails to timely make any report or payment required by this subsection for any reason.

(6) Assessments of additional Georgia income tax, interest, and penalties arising from final federal adjustments. The commissioner will assess additional Georgia income tax, interest, and penalties arising from final federal adjustments as if it is a tax imposed by this chapter unless a different treatment is provided by this subsection. Since partnership adjustments are determined at the audited partnership level, any assessment issued to partners shall not be appealable by the partner. Any penalties or interest imposed on the partnership or its partners shall be as provided and at the rates in this title except that penalties and interest imposed on the audited partnership or tiered partners shall be from the day after the due date of the reviewed year return without extension. Such assessment shall be issued by the following dates:

(A) Timely reported final federal adjustments. If a partnership, tiered partner, or other partner files with the commissioner a federal adjustments report as required within the period specified in this subsection reporting all final federal adjustments, the commissioner may assess any taxes, including on-behalf taxes, interest, and penalties arising from those final federal adjustments if the commissioner issues a notice of assessment to the partnership, tiered partner, or partner, on or before the later of:

(i) The expiration of the limitations period specified in Code Section 48-7-82; or

(ii) The expiration of the one-year period following the date of filing with the commissioner of the federal adjustments report by such person.

(B) Untimely reported final federal adjustments. If the partnership, tiered partner, or other partner fails to file the federal adjustments report within the period specified in this subsection, or the federal adjustments report filed by the partnership, tiered partner, or other partner omits final federal adjustments or understates the correct amount of Georgia income tax owed, the commissioner may assess any taxes, including on-behalf taxes, interest, and penalties arising from the final federal adjustments, if it issues a notice of assessment to the partnership, tiered partner, or other partner on or before the later of:

(i) The expiration of the limitations period specified in Code Section 48-7-82;

(ii) The expiration of the one-year period following the date the federal adjustments report was filed with commissioner by such person; or

(iii) Absent fraud, the expiration of the five-year period following the date on which the Internal Revenue Service notifies the commissioner of the federal adjustments.

(7) Claims for refund of Georgia income tax arising from final federal adjustments. Notwithstanding the reporting requirement contained in this subsection and except as otherwise prohibited by this title, a partnership, tiered partner, or other partner, as the case may be, may file a claim for refund of Georgia income tax arising directly or indirectly from final federal adjustments on or before the later of:

(A) The expiration of the last day for filing a claim for refund of Georgia income tax pursuant to Code Section 48-2-35 for such person; or

(B) One year from the date the federal adjustments report was required to be filed by this subsection for such person.

(8) Scope of adjustments and extensions of time.

(A) Unless otherwise agreed in writing by the partnership, tiered partner, or other partner and the commissioner, any adjustments by the commissioner after the expiration of the time provided in Code Section 48-7-82 or by the partnership, tiered partners, or other partners made after the expiration of the time provided in Code Section 48-2-35, are limited to changes to the partnership's, tiered partner's, or other partner's Georgia income tax liability arising directly or indirectly from final federal adjustments.

(B) Where, before the expiration of the time prescribed in this subsection for the assessment of Georgia income tax, both the commissioner and the person subject to assessment have consented in writing to its assessment after such time, the tax may be assessed at any time prior to the expiration of the agreed upon period. The period so agreed upon may be extended by subsequent agreements in writing made before the expiration of the previously agreed upon period and the commissioner is authorized in any such agreement to extend similarly the period within which a claim for refund may be filed; provided, however, that the time periods provided in this subsection may be extended automatically by 60 days for an audited partnership which has 10,000 or more direct partners or a tiered partner which has 10,000 or more partners that hold an interest directly in such tiered partner, provided that such audited partnership or tiered partner attaches a statement to its federal adjustments report specifying that it has elected such automatic extension.

(9) Any income subtracted from federal taxable income for the adjustment year pursuant to Section 6225 of the Internal Revenue Code of 1986 and the regulations thereunder shall be added to the partnership's, tiered partner's, or other partner's Georgia taxable net income for the adjustment year.

(d) For taxable years beginning on or after January 1, 2017, any adjustment to a partnership's items of income, gain, loss, expense, or credit or an adjustment to such items allocated to a partner that holds an interest in a partnership for the reviewed year by the commissioner as a result of a state partnership audit shall be determined at the partnership level in the same manner as provided by subsection (a) of Section 6221 of the Internal Revenue Code of 1986 and the regulations thereunder unless a different treatment is specifically provided in this title. If the commissioner and the partnership agree, the provisions of this subsection may be applied to taxable years beginning before January 1, 2017. The provisions of Sections 6222, 6223, and 6227 of the Internal Revenue Code of 1986 and the regulations thereunder shall also apply in the same manner as provided in such sections unless a different treatment is specifically provided in this chapter. For purposes of applying such sections, due account shall be made for differences in federal and Georgia terminology such as substitution of "Secretary" with "Commissioner" and other obvious differences. The adjustment provided by subsection (a) of Section 6221 of the Internal Revenue Code of 1986 shall be determined as provided in such section but shall be based on the Georgia taxable net income or other tax attributes of the partnership as determined pursuant to this chapter for the reviewed year. The commissioner shall issue a notice of adjustment to the partnership. Such notice shall be treated as an assessment for purposes of Code Sections 48-2-59 and 48-7-82, and, as such, the notice shall be appealable pursuant to Code Section 48-2-59 and shall be issued within the time period provided by Code Section 48-7-82. Once the adjustments to partnership-related items or reallocations of income, expenses, gains, losses, credits, and other attributes among such partners for the reviewed year are finally determined, the partnership and any direct partners or indirect partners shall then be subject to the provisions of subsection (c) of this Code section in the same manner as if the state partnership audit were a partnership level audit.

(e) For purposes of this chapter, any adjustment to a pass-through entity's items of income, gain, loss, expense, or credit or an adjustment to such items allocated to a partner that holds an interest in a pass-through entity for the reviewed year by the commissioner shall be determined in the same manner as provided in subsection (d) of this Code section.

(f) An administrative adjustment request filed by the partnership with the Internal Revenue Service or the commissioner shall be treated in the reviewed year in the same manner as provided by subsection (c) of this Code section, except that:

(1) The period of limitations on claiming refunds for the partnership and partners shall be as provided by this title, notwithstanding subsection (c) of this Code section; and

(2) The period of limitations on making adjustments and assessments for the partnership and partners shall be on or before the later of:

(A) The expiration of the limitations period specified in Code Section 48-7-82; or

(B) The expiration of the one-year period following the date of the filing of the administrative adjustment request by the partnership or the amended Georgia income tax return by the partners, as the case may be.

(g) The commissioner shall be authorized to promulgate any rules and regulations necessary to implement and administer the provisions of this Code section.
