OAR 150-314-0345
Apportionment and Allocation of Income Generally
(1)
If the business activity in respect to any trade or business of a taxpayer occurs both within and without this state, and if by reason of such business activity the taxpayer is taxable in another state, the portion of net income (or net loss) arising from such trade or business which is derived from sources within this state must be determined by apportionment in accordance with ORS 314.615 (When allocation and apportionment of net income from business activity required) to 314.675 (Apportionment of net loss). In such cases, the first step is to determine which portion of the taxpayer’s entire net income constitutes apportionable income and which portion constitutes nonapportionable income. The various items of nonapportionable income are then directly allocated to specific jurisdictions pursuant to the provisions of ORS 314.625 (Certain nonapportionable income to be allocated) to 314.645 (Allocation to this state of patent and copyright royalties). The apportionable income (or loss) of the taxpayer is divided between the jurisdictions in which the business is conducted pursuant to the property, payroll, and sales apportionment factors set forth in ORS 314.650 (Apportionment of income) to 314.665 (Determination of sales factor) and ORS 314.675 (Apportionment of net loss). The sum of (1) the items of nonapportionable income (or loss) directly allocated to this state, plus (2) the amount of apportionable income (or loss) attributable to this state by the apportionment formula constitutes the amount of the taxpayer’s entire net income which is subject to tax under the income tax laws of this state.
