  5.  Election for partnership or tiered partners to pay. 
  a.  An audited partnership, or a tiered partner of an audited partnership that receives a notification under subsection 4 of a final federal partnership adjustment arising from a partnership level audit, may make an election to pay as provided under this subsection.
  b.  An audited partnership or tiered partner shall make an election to pay under this subsection in the manner and form prescribed by the department. The audited partnership or tiered partner making an election to pay shall file a completed federal adjustments report, notify each of the direct partners of such partner’s distributive share of the adjustments, and pay on behalf of its partners an amount calculated in paragraph “c”, including any applicable penalty and interest. These requirements shall all be fulfilled within one of the following time periods:
  (1)  For the audited partnership, no later than ninety days after the final determination date of the audited partnership.

  (3)  For an indirect tiered partner, within ninety days after the time for filing and furnishing statements to a tiered partner and the partner of the tiered partner, as established by section 6226 of the Internal Revenue Code and the regulations thereunder.
  c.  The amount due under this subsection from an audited partnership or tiered partner shall be calculated as follows:
  (1)  Exclude from final federal partnership adjustments and any positive reallocation adjustments the distributive share of such adjustments reported to an exempt partner that holds an interest directly in the audited partnership if the audited partnership is making the election or that holds an interest directly in the tiered partner if the tiered partner is making the election, but only to the extent the distributive share is not unrelated business income.
  (2)  Determine the total distributive share of all final federal partnership adjustments and positive reallocation adjustments as modified by this title that are reported to corporate partners, and to exempt partners to the extent the distributive share is unrelated business income, and allocate and apportion such adjustments as provided in section 422.33 at the partnership or tiered partner level, and multiply the resulting amount by the maximum state corporate income tax rate pursuant to section 422.33 for the reviewed year. 
  (3)  Determine the total distributive share of all final federal partnership adjustments and positive reallocation adjustments as modified by this title that are reported to nonresident individual partners and nonresident fiduciary partners and allocate and apportion such adjustments as provided in section 422.33 at the partnership or tiered partner level, and multiply the resulting amount by the maximum individual income tax rate pursuant to section 422.5A for the reviewed year.
  (4)  For the total distributive share of all final federal partnership adjustments and positive reallocation adjustments as modified by this title that are reported to tiered partners:
  (a)  Determine the amount of such adjustments which are of a type that would be subject to sourcing to Iowa under section 422.8, subsection 2, paragraph “a”, as a nonresident, and then determine the portion of this amount that would be sourced to Iowa under those provisions as if the tiered partner were a nonresident.
  (b)  Determine the amount of such adjustments which are of a type that would not be subject to sourcing to Iowa under section 422.8, subsection 2, paragraph “a”, as a nonresident. 
  (c)  Determine the portion of the amount in subparagraph division (b) that can be established, as prescribed by the department by rule, to be properly allocable to indirect partners that are nonresident partners or other partners not subject to tax on the adjustments.
  (d)  Multiply the total of the amounts determined in subparagraph divisions (a) and (b), reduced by any amount determined in subparagraph division (c), by the highest individual income tax rate pursuant to section 422.5A for the reviewed year. 
  (5)  For the total distributive share of all final federal partnership adjustments and positive reallocation adjustments as modified by this title that are reported to resident individual partners and resident fiduciary partners, multiply that amount by the highest individual income tax rate pursuant to section 422.5A for the reviewed year.
  (6)  (a)  Total the amounts computed pursuant to subparagraphs (2) through (5) and calculate any interest and penalty as provided under this title. Notwithstanding any provision of law to the contrary, interest and penalties on the amount due by the audited partnership or tiered partner shall be computed from the due date of the reviewed year return without extension, and shall be imposed as if the audited partnership or tiered partner was required to pay tax or show tax due on the original return for the reviewed year, except that a specified business subject to the penalty in section 421.27, subsection 1, paragraph “b”, for the reviewed year shall not also be subject to the penalty in section 421.27, subsection 1, paragraph “a”, on the amount due for that reviewed year pursuant to the election to pay.
  (b)  The director may establish rules providing for the calculation of amounts due under this subsection for federal partnership adjustments that affect state tax owed but that do not fit within the calculation in subparagraphs (2) through (5), such as tax credit changes. The director may establish rules that include changes related to state-specific issues following a state partnership audit in the election to pay and calculation of amounts due under this subsection, including but not limited to allocation and apportionment. Interest and penalty shall be computed in the same manner as described in subparagraph division (a).
  d.  Adjustments subject to the election in this subsection do not include any adjustments arising from an administrative adjustment request.
  e.  An audited partnership or tiered partner not otherwise subject to any reporting or payment obligation to Iowa that makes an election under this subsection consents to be subject to the Iowa laws related to reporting, assessment, collection, and payment of Iowa tax, interest, and penalties calculated under the election. 
  6.  Modified reporting and payment method.  The department may adopt procedures for an audited partnership or tiered partner to enter into an agreement with the department to use an alternative reporting and payment method, including applicable time requirements or any other provision of this section. The audited partnership or tiered partner must demonstrate that the requested method will reasonably provide for the reporting and payment of taxes, penalties, and interest due under the provisions of this section. Application for approval of an alternative reporting and payment method must be made by the audited partnership or tiered partner within the time for making an election to pay under subsection 5 and in the manner prescribed by the department. Approval of such an alternative reporting and payment method shall be at the discretion of the department.
  7.  Effect of election by partnership or tiered partner and payment of amount due.
  a.  The election made under subsection 5 is irrevocable, unless in the discretion of the director, the director determines otherwise.
  b.  The amount determined in subsection 5, when properly reported and paid by the audited partnership or tiered partner, shall be treated as paid on behalf of the partners of such audited partnership or tiered partner on the same final federal partnership adjustments, provided, however, that no partner may take any deduction or credit for the amount, claim a refund of the amount, or include the amount on such partner’s Iowa return in any manner.
  c.  In the event another state offers to an audited partnership or tiered partner a similar election to pay state tax resulting from final federal partnership adjustments, nothing in this subsection shall prohibit a resident who holds an interest directly in that audited partnership or tiered partner, as the case may be, from claiming a credit for taxes paid by the resident to another state under section 422.8, subsection 1, for any amounts paid by the audited partnership or tiered partner on such resident partner’s behalf to another state, provided such payment otherwise meets the requirements of section 422.8, subsection 1.
  d.  Nothing in this section shall prohibit the department from assessing direct partners and indirect partners for taxes they owe in the event that a partnership or tiered partner fails to timely make any report or payment required by this section for any reason. 
  8.  Assessments of additional Iowa income tax, interest, and penalties, and claims for refund, arising from final federal partnership adjustments.
  a.  The department shall assess additional Iowa income tax, interest, and penalties arising from final federal partnership adjustments in the same manner as provided in this title unless a different treatment is provided by this subsection. Since final federal partnership adjustments are determined at the partnership level, any assessment issued to partners shall not be appealable by the partner. The department may assess any taxes, including on-behalf-of amounts, interest, and penalties arising from the final federal partnership adjustments if it issues a notice of assessment to the partnership, tiered partner, or other direct or indirect partner on or before the expiration of the applicable limitations period specified in section 422.25. 
  b.  In addition to the period for claiming a refund or credit provided in section 422.73, subsection 1, paragraph “a”, and notwithstanding section 422.73, subsection 1, paragraph “b”, a partnership, tiered partner, or other direct or indirect partner, as the case may be, may file a claim for refund of Iowa income tax arising directly or indirectly from a final federal partnership adjustment arising from a partnership level audit on or before the date which is one year from the date the federal adjustments report for that final federal partnership adjustment was required to be filed by such person under this section.
  9.  Rules.  The department may adopt any rules pursuant to chapter 17A to implement this section.
