  2. (B) If a trade or business has federal unrelated business taxable income of less than zero (0) for a taxable year, the taxpayer shall apply the modifications under this section for the taxable year against the net operating loss in the manner required under IC 6-3-2-2.5 and IC 6-3-2-2.6 for separately stated net operating losses. However, if the application of modifications required under IC 6-3-2-2.5 or IC 6-3-2-2.6 results in the separately stated net operating loss for the trade or business being zero (0), the modifications that increase adjusted gross income under this section and remain after the calculations to adjust the separately stated net operating loss to zero (0) that result from the trade or business must be treated as modifications to which clause (A) applies for the taxable year.
  3. (C) If a trade or business otherwise described in Section 512(a)(6) of the Internal Revenue Code incurred a net operating loss for a taxable year beginning after December 31, 2017, and before January 1, 2021, and the net operating loss was carried back for federal tax purposes:
    1. (i) if the loss was carried back to a taxable year for which the requirements under Section 512(a)(6) of the Internal Revenue Code did not apply, the portion of the loss and modifications attributable to the loss shall be treated as adjusted gross income of the taxpayer for the first taxable year of the taxpayer beginning after December 31, 2022, and shall be treated as part of the adjusted gross income attributable to clause (A), unless, and to the extent, the loss and modifications were applied to adjusted gross income for a previous taxable year, as determined under this article; and
    2. (ii) if the loss was carried back to a taxable year for which the requirements under Section 512(a)(6) of the Internal Revenue Code applied, the portion of the loss and modifications attributable to the loss shall be treated as adjusted gross income of the taxpayer for the first taxable year of the taxpayer beginning after December 31, 2022, and for purposes of this clause, the inclusion of losses and modifications shall be in the same manner as provided in clause (B), unless, and to the extent, the loss and modifications were applied to adjusted gross income for a previous taxable year, as determined under this article.
  4. (D) Notwithstanding any provision in this subdivision, if a taxpayer computed its adjusted gross income for a taxable year beginning before January 1, 2023, based on a reasonable interpretation of this article, the taxpayer shall be permitted to compute its adjusted gross income for those taxable years based on that interpretation. However, a taxpayer must continue to report any tax attributes for taxable years beginning after December 31, 2022, in a manner consistent with its previous interpretation.
2. (2) In the case of a corporation, other than a captive real estate investment trust, for which the adjusted gross income under this article is determined after a deduction for dividends paid under the Internal Revenue Code, the modifications required under this section shall be applied in ratio to the corporation's taxable income (as defined in Section 63 of the Internal Revenue Code) after deductions for dividends paid under the Internal Revenue Code compared to the corporation's taxable income (as defined in Section 63 of the Internal Revenue Code) before the deduction for dividends paid under the Internal Revenue Code.
3. (3) In the case of a trust or estate, the trust or estate is required to include only the portion of the modifications not passed through to beneficiaries.
4. (4) In the case of a taxpayer for which modifications are required to be applied against a separately stated net operating loss under IC 6-3-2-2.5 or IC 6-3-2-2.6 , the modifications required under this section must be adjusted to reflect the required application of the modifications against a separately stated net operating loss, in order to avoid the application of a particular modification multiple times.
