      317.010 Definitions. As used in this chapter, unless the context requires otherwise:

      (1) “Centrally assessed corporation” means every corporation the property of which is assessed by the Department of Revenue under ORS 308.505 to 308.674.

      (2) “Department” means the Department of Revenue.

      (3)(a) “Consolidated federal return” means the return permitted or required to be filed by a group of affiliated corporations under section 1501 of the Internal Revenue Code.

      (b) “Consolidated state return” means the return required to be filed under ORS 317.710 (5).

      (4) “Doing business” means any transaction or transactions in the course of its activities conducted within the state by a national banking association, or any other corporation; provided, however, that a foreign corporation whose activities in this state are confined to purchases of personal property, and the storage thereof incident to shipment outside the state, shall not be deemed to be doing business unless such foreign corporation is an affiliate of another foreign or domestic corporation which is doing business in Oregon. Whether or not corporations are affiliated shall be determined as provided in section 1504 of the Internal Revenue Code.

      (5) “Excise tax” means a tax measured by or according to net income imposed upon national banking associations, all other banks, and financial, centrally assessed, mercantile, manufacturing and business corporations for the privilege of carrying on or doing business in this state.

      (6) “Financial institution” has the meaning given that term in ORS 314.610 except that it does not include a credit union as defined in ORS 723.006, an interstate credit union as defined in ORS 723.001 or a federal credit union.

      (7) “Internal Revenue Code,” except where the Legislative Assembly has provided otherwise, refers to the laws of the United States or to the Internal Revenue Code as they are amended and in effect:

      (a) On December 31, 2023; or

      (b) If related to the definition of taxable income, as applicable to the tax year of the taxpayer.

      (8) “Oregon taxable income” means taxable income, less the deduction allowed under ORS 317.476, except as otherwise provided with respect to insurers in subsection (11) of this section and ORS 317.650 to 317.665.

      (9) “Oregon net loss” means taxable loss, except as otherwise provided with respect to insurers in subsection (11) of this section and ORS 317.650 to 317.665.

      (10) “Taxable income or loss” means the taxable income or loss determined, or in the case of a corporation for which no federal taxable income or loss is determined, as would be determined, under chapter 1, Subtitle A of the Internal Revenue Code and any other laws of the United States relating to the determination of taxable income or loss of corporate taxpayers, with the additions, subtractions, adjustments and other modifications as are specifically prescribed by this chapter except that in determining taxable income or loss for any year, no deduction under ORS 317.476 or 317.478 and section 45b, chapter 293, Oregon Laws 1987, shall be allowed. If the corporation is a corporation to which ORS 314.280 or 314.605 to 314.675 (requiring or permitting apportionment of income from transactions or activities carried on both within and without the state) applies, to derive taxable income or loss, the following shall occur:

      (a) From the amount otherwise determined under this subsection, subtract nonapportionable income, or add nonapportionable loss, whichever is applicable.

      (b) Multiply the amount determined under paragraph (a) of this subsection by the Oregon apportionment percentage defined under ORS 314.280, 314.650 or 314.667, whichever is applicable. The resulting product shall be Oregon apportioned income or loss.

      (c) To the amount determined as Oregon apportioned income or loss under paragraph (b) of this subsection, add nonapportionable income allocable entirely to Oregon under ORS 314.280 or 314.625 to 314.645, or subtract nonapportionable loss allocable entirely to Oregon under ORS 314.280 or 314.625 to 314.645. The resulting figure is “taxable income or loss” for those corporations carrying on taxable transactions or activities both within and without Oregon.

      (11) As used in ORS 317.650 to 317.665, “insurer” means any domestic, foreign or alien insurer as defined in ORS 731.082 and any interinsurance and reciprocal exchange and its attorney in fact with respect to its attorney in fact net income as a corporate attorney in fact acting as attorney in compliance with ORS 731.458, 731.462, 731.466 and 731.470 for the reciprocal or interinsurance exchange. However, “insurer” does not include title insurers or health care service contractors operating pursuant to ORS 750.005 to 750.095.
