OAR 150-317-0540: Consolidated Oregon Return: Format and Information Required

(1) Generally, the consolidated Oregon return must be filed by and in the name of the common parent corporation. If the common parent corporation is not a member of the affiliated group filing the consolidated Oregon return or is not subject to Oregon taxation, the return must be filed in the name of a member of the affiliated group doing business in Oregon as defined under ORS 317.010(4). If more than one member is doing business in Oregon, the name of the member having the greatest presence in Oregon must be used. If the name under which a prior year’s consolidated Oregon return was filed is changed, a statement must be attached to the current year’s return advising the department of the name change. (2) If the affiliated group filing a consolidated federal return consists of more than one unitary group, each unitary group that includes an Oregon taxpayer must file a separate consolidated Oregon return. (3) For purposes of this section “having the greatest presence” means having the largest Oregon property value as determined under ORS 314.655. (4) The consolidated Oregon return must be prepared in columnar form reflecting separately, for each member of the affiliated group, and in total, the federal consolidated taxable income, the modifications required by ORS 317.259, the tax credits, and any other information requested by the department. If taxable income is determined under ORS 317.010(10)(a) to (c), the nonapportionable income or loss and apportionment formula must also be reflected separately for each member of the affiliated group and in total. (5) A schedule of corporations subject to Oregon’s jurisdiction to tax must be attached to the consolidated Oregon return.
